Stuart Hall was a Jamaican-born, British-based theorist, critic, and activist, who flourished between the late 1950s and his death in 2014. Known both for his theoretical and empirical work on culture and communication and for his role as a public intellectual, Hall produced scholarly writings and charismatic teaching that were matched by his columns and interviews in magazines and newspapers and appearances on television and radio.
Substance Abuse Prevention Message Generation: Engaging Adolescents in Health Message Planning and/or Production of Health Promotion Messages
Smita C. Banerjee and Kathryn Greene
Adolescent substance use remains a significant public health challenge, with recent approaches to address these problems including actively engaging adolescents in message planning and/or production as a prevention strategy. There are two benefits of this active involvement strategy. First, engaging adolescents in message planning or producing substance prevention messages is a form of participatory research that results in participant-generated messages for use in future intervention efforts. This participatory form of research is increasingly common in a wide range of topics and populations, particularly disenfranchised or stigmatized groups. It is important to focus on the second benefit of engaging adolescents in message planning and prevention: the effect of engaging in planning or producing substance prevention messages on the adolescents themselves. If done properly, the process of engaging adolescents in planning (or producing) anti-substance messages can provide longer-term benefits of delaying onset of substance use (strengthening resistance) as well as changing patterns for those already using. Some examples of this strategy exist with media literacy, although applied with a great deal of variability. The increased popularity of these planning/production approaches requires greater explication of how, when, and why they produce effects for participants. Two different theoretical perspectives address this active involvement intervention approach: narrative engagement theory and the theory of active involvement. Beyond these theories, sensation seeking is positioned as a moderator to explore for active involvement intervention effects.

Social support in the context of chronic illness management is important, as individuals diagnosed with these conditions and their loved ones often experience increased distress, reduced relational quality, and diminished physical health as a result of coping with these long-term symptoms. Therefore, diagnosed individuals and their close relational partners rely on others to provide support in their time of need. The communication of social support is characterized by “verbal and nonverbal behavior produced with the intention of providing assistance to others perceived of needing that aid” (MacGeorge, Feng, & Burleson, 2011, p. 317). Individuals living with these chronic illnesses and their loved ones often turn to a variety of interpersonal others, including friends, family, health care providers, and support groups to manage the difficulties that accompany their physical symptoms. Although some researchers suggest that diagnosed individuals seek support most frequently from close relational partners, other scholars assert that chronic care support groups (whether meeting face to face or via computer-mediated channels) offer support recipients an opportunity to discuss their challenges and receive help from experientially similar others.
On the one hand, regardless of the support provider, individuals who have been diagnosed with chronic conditions generally perceive effective supportive communication to be messages in which their support providers enact competent tangible assistance in managing the illness, provide an opportunity for them to vent their feelings, and express messages of empathy and affection, among others. Ineffective messages, on the other hand, are those in which diagnosed individuals feel their partners are overly involved in helping them make decisions about their care or portraying negative attitudes or discomfort around them. Overall, research in this area suggests that support recipients and their relational partners have improved emotional, relational, and physical outcomes when they perceive support to be available or receive effective support from these resources.
Current communications research takes up the political and ethical problems posed by new surveillance technologies in public space, ranging from biometric technologies adopted by state security apparatuses to self- and peer-monitoring applications for the consumer market. In addition to studies that examine new surveillance technologies, scholars are tracking intensive and extensive expansions of surveillance in the name of risk management. Much of the scholarship produced in the last 15 years looks at how the establishment and expansion of the Department of Homeland Security within the United States and its international counterparts have dramatically altered security, military, and legal practices and cultures. Within this context what were once science fiction dystopias have become funded research and development projects and institutionalized practices aimed at remote data collection and processing, including facial recognition technology and a variety of remote sensing devices. Private-public partnerships between companies like Google and Homeland Security fusion centers have made it possible to use GPS technology to network data that promises to help manage a variety of natural and man-made disasters.

Observing, describing, and analyzing journalism as part of society requires theories on a macro level. Unlike normative theories, which criticize journalism with respect to its achievements and failures within society, systems theory operates with the concept of function in a non-normative sense. Based on the groundwork of Talcott Parsons’ theory of social systems, Niklas Luhmann developed systems theory further and radicalized it by strictly avoiding any kind of structural conservatism. His approach is built on the assumption that social systems operate autonomously on the basis of the functional differentiation to their environment. Macro-level systems, i.e., societal systems, fulfill unique functions for and within society. Functional autonomy and singularity make a modern society highly efficient but force each system to rely on the functional performances of all other societal systems. Hence, societal systems are structurally coupled and interdependent. Epistemologically, systems do not exist as ontological units but are strictly observer-related, be the observer the system itself or an external observer, such as the scientific community is.
In journalism research, Luhmann’s systems theory has been applied to journalism as a societal system. Several competing approaches with different perspectives on the system observed (journalism, the mass media, or the public sphere) have been developed with respect to identifying the basic characteristics on which the system operates. Despite their differences they have this in common: journalism is not considered the sum of individual journalists and their (individual) way of working, instead, the systems-theoretical perspective is holistic. However, compared to theories of professionalism, which is also a holistic concept, systems theory neither identifies journalism with the profession of journalism, nor commits it to professional journalism. Instead, the structure of journalism is flexible, i.e., functionally equivalent, as long as its function is fulfilled. This function can be specified: journalism provides society periodically with current, independent, factual, and relevant information.
Empirically, systems theory helps defining the population of journalists by deducing it from its function. Unlike mere empirical approaches, which arbitrarily draw samples from an unknown population, it is possible to clearly draw distinctions between journalism and other forms of public communication, such as public relations, advertising, propaganda, or lay communication. Still, it is challenging to operationalize such an abstract theory, as it is not specially made for hypothesis-driven research.
As the use of online technologies has grown in recent years, so has the study of computer-mediated communication.
Online communication began in universities through the use of e-mail. Soon, spaces such as multi-user dungeons (MUDs), Listserv, and bulletin boards were developed, which not only allowed people who knew each other offline to interact but also enabled individuals who were not previously acquainted to communicate via the Internet. The development of Web 2.0, which allowed for more user-generated content, led to new and innovative ways of interacting online, most notably thorough social media sites. Social media sites, such as Facebook and Twitter, allow not only for text-based interaction to occur but also for image- and video-based interaction.
Through all these developments, interactional norms and practices have developed. A key factor in these norms is what the medium enables, or affords, participants to do. Features such as whether an interactional platform is synchronous or asynchronous can impact the nature of the interaction. Similarly, the lack of visual or verbal contact when interacting may impact upon the interaction, through the potential for misunderstandings. Participants do, though, develop practices to suit the medium. If we examine these practices in detail, it is possible to also analyze the role which technology plays in the interaction. One method that has been used to do this is conversation analysis, which was developed for and using spoken interaction. Conversation analysis examines conversation in forensic detail to illuminate the norms and practices through which we conduct our everyday lives. In using this method for analyzing online interaction, we can not only understand the practices but also examine the affordances of particular interactional platforms.
Various interactional features of computer-mediated communication (CMC) have been examined from a conversation analytic perspective, including sequential organization, openings, turn-taking, and repair. A common focus of these studies it to explore the interactional patterns but also to understand how these might be impacted by the technology itself. The development of norms for a variety of forms of technologized interaction demonstrates how individuals are capable of adapting their interactional practices for new contexts.

Terrorism employs violence or the threat of violence to diffuse and amplify messages to an audience beyond the immediate target or victim of an attack. Violent acts initiate media coverage, as well as word-of-mouth transmission, functioning as a gateway that draws attention to the terror group and its messages in a manner that increases the salience of the communication; then media provides additional information contextualizing the original act. Media coverage may make the group initiating the communication look more dangerous or powerful than is warranted.
Terrorist communication strategy involves a noteworthy violent act, or threat thereof, that secondarily communicates with multiple audience groups. One audience may be supporters of the terror group who construct identity from the violent act as well as from grievances that the group seeks to advertise. Another may be outgroups sympathetic with the substance of communicated messages. Still another may be foreign countries, which may provide a sense of legitimacy to the actions of the group.
A violent group successfully portrayed as victimized will solidify ingroup cohesion and outgroup hostility while justifying the use of violence as a moral consequence of circumstances. Terrorists often dehumanize the outgroup by stereotyping them in ways they argue will justify violence. People sympathetic with the dehumanization of the outgroup may provide support without actually joining in the perpetration of terror. Some may be radicalized by communication produced by terrorists, such as on social media, to become actors themselves. Counter-terror tactics may disrupt intergroup communication, thus interfering with recruitment or operational capabilities of those supporting or engaging in terrorism.

A majority of the extant literature in health and risk message processing focuses—for obvious reasons—on social influence and compliance-gaining. Interpersonal and relational issues with doctors and patients are a secondary focus. In contrast, research that specifically addresses comprehension of health and risk messaging is somewhat scant. However, other domains (e.g., cognitive psychology, reading studies) offer models and studies of comprehension that address message processing more generally. This material can usefully inform research in a health and risk context.
An important aspect of any communicative event is the degree to which that event allows interactivity. This can be described in terms of a continuum from static messaging to dynamic messaging. Message features may affect simple comprehension (in the former case) and active understanding (in the latter case) of messaging along this continuum. For static messaging, text features are the dominant focus; for dynamic messaging, how communicators cooperate, collaborate, and adjust their behavior relative to each other’s knowledge states is the focus. Moderators of these effects, which include sources’ dual goals informing and influencing targets, are also important to consider. Examples of this include direct-to-consumer-advertising (DTCA) of pharmaceutical medicines and pharmaceutical companies, which must meet the demands of the government regulatory bodies (e.g., fair and balanced presentation of benefits and risks) while simultaneously influencing the message processing experience of the target to minimize negative perceptions of their products. Impediments to creating understanding can arise in both the highly interactive setting of the face-to-face doctor-patient context as well as more static messaging situations such as PSAs, pamphlets, and pharmaceutical package inserts.
Making sense of message comprehension in health and risk communication is complex, and it is complex because it is broad in scope. Health and risk communication runs the gamut of static to dynamic messaging, employing everything from widely distributed patient information leaflets and public service announcements, to interactive web pages and massively connected social networking sites, to the highly interactive and personalized face-to-face meeting between doctor and patient. An equally comprehensive theoretical and methodological tool box must be employed to develop a thorough understanding of health and risk communication.
The ACT2 Program and Eliminating Racial and Ethnic Disparities in HIV and AIDS Clinical Trials: A Case Study in Health and Risk Messaging
Marya Gwadz and Amanda S. Ritchie
It is well documented that African American/Black and Hispanic individuals are underrepresented in biomedical research in the United States (U.S.), and leaders in the field have called for the proportional representation of varied populations in biomedical studies as a matter of social justice, economics, and science. Yet achieving appropriate representation is particularly challenging for health conditions that are highly stigmatized such as HIV/AIDS. African American/Black, and Hispanic individuals, referred to here as “people of color,” are greatly overrepresented among the 1.2 million persons living with HIV/AIDS in the United States. Despite this, people of color are substantially underrepresented in AIDS clinical trials. AIDS clinical trials are research studies to evaluate the safety and effectiveness of promising new treatments for HIV and AIDS and for the complications of HIV/AIDS, among human volunteers. As such, AIDS clinical trials are critical to the development of new medications and treatment regimens. The underrepresentation of people of color in AIDS clinical trials has been criticized on a number of levels. Of primary concern, underrepresentation may limit the generalizability of research findings to the populations most affected by HIV/AIDS. This has led to serious concerns about the precision of estimates of clinical efficacy and adverse effects of many treatments for HIV/AIDS among these populations. The reasons for the underrepresentation of people of color are complex and multifaceted. First, people of color experience serious emotional and attitudinal barriers to AIDS clinical trials such as fear and distrust of medical research. These experiences of fear and distrust are grounded largely in the well-known history of abuse of individuals of color by medical research institutions, and are complicated by current experiences of exclusion and discrimination in health care settings and the larger society, often referred to as structural racism or structural violence. In addition, people of color experience barriers to AIDS clinical trials at the level of social networks, such as social norms that do not support engagement in medical research and preferences for alternative therapies. People of color living with HIV/AIDS experience a number of structural barriers to clinical trials, such as difficulty accessing and navigating the trials system, which is often unfamiliar and daunting. Further, most health care providers are not well positioned to help people of color overcome these serious barriers to AIDS clinical trials in the context of a short medical appointment, and therefore are less likely to refer them to trials compared to their White peers. Last, some studies suggest that the trials’ inclusion and exclusion criteria exclude a greater proportion of people of color than White participants. Social/behavioral interventions that directly address the historical and contextual factors underlying the underrepresentation of people of color in AIDS clinical trials, build motivation and capability to access trials, and offer repeated access to screening for trials, hold promise for eliminating this racial/ethnic disparity. Further, modifications to study inclusion criteria will be needed to increase the proportion of people of color who enroll in AIDS clinical trials.

The Breast Cancer and Environment Research Program (BCERP) is a transdisciplinary program of research created to investigate environmental exposures and their relationship to breast cancer with a particular focus on puberty as a potential window of increased susceptibility to environmental exposures. A transdisciplinary approach has a strong focus on translating scientific findings into usable health practices as well as health prevention messages so that current research informs practice as well as communication to the lay public. BCERP engaged in communication science to develop health messages for lay audiences, health professionals, and outreach organizations. The precautionary principle, used as a primary guide in regards to message translation and dissemination, yields a useful discussion of the BCERP organizational structure. An exploration of formative communication science efforts in BCERP, areas of sensitivity for creating BCERP messages, and resources created for BCERP toolkits serves to illustrate and describe this one approach to designing health and risk messages.

Depending on how you approach it, economic justice is either an extremely old intellectual tradition or a relatively new one. From the first perspective, economic justice is part and parcel of classical political philosophy—Plato’s The Republic and Aristotle’s The Politics, for instance, both discuss property distribution in an ideal society, emphasizing the philosophy of justice over economic precepts. From the second perspective, the one we embrace, economic justice is a uniquely modern inquiry that emerged with the writings of Karl Marx and his revolutionary critique of the capitalist political economy. For Marx, economic justice can be understood as a critical enterprise that attempts to locate contradictions between universal and particular conceptions of human freedom and intervene politically into these contradictions with the aim of creating a more just, equitable, and egalitarian society. So conceived, economic justice liberates the collective potential of humanity from its exploitation and degradation by capitalism as well as the various legal institutions it develops to control human behavior for the purpose of extracting of surplus-value. It is this Marxist perspective and the various historical reformulations that it has authorized that influence the way rhetoricians and scholars of cultural studies conceptualize economic justice in the discipline of communication. While not all of these scholars endorse an explicitly Marxist line of thought, they all attempt to conceptualize economic justice as a normative political category that influences various models of rhetorical agency and social change.

Journalism seeks to observe and communicate what it learns of social importance, something called news, and in doing so is always in the process of creating a public by bringing it into synchronized conversation with itself. Theories of journalism provide explanatory frameworks for understanding a complex combination of social practice, product, and institutional arrangement. Journalism’s late 20th-century professionalized, high modern version, which is still recognizable today, has continued to change, particularly with the disruptive effect of the Internet, as it has evolved to absorb other forms. The boundaries of profession and news organization have been destabilized within this rapidly shifting media terrain, but still there remain productive approaches for systematically organizing knowledge around the concept of journalism.
The early 20th-century perspectives on journalism—before becoming linked to the communication field and a more narrow media effects focus—were at home in the University of Chicago school of sociology, which emphasized community-based, multi-method participant observation. A sociology of news perspective resurfaced with more ethnographic research in newsrooms in the 1950s, and theories of journalism have continued to highlight the ethnographic method, especially in understanding the impact of technology on a more digitally-oriented journalism practice. A hierarchy of influences perspective, developed by Shoemaker and Reese, incorporates other perspectives beyond the ethnographic by considering factors at multiple levels of analysis that shape media content, the journalistic message system, from the micro to the macro: individual characteristics of specific newsworkers, their routines of work, organizational-level concerns, institutional issues, and the larger social system. At each level, one can identify the main factors that shape the symbolic reality constituted and produced by journalism, as well as how these factors interact across levels and compare across different contexts (e.g., national, technological).
A hierarchy of influences model worked well to disentangle the relationships among professionals and their routines, and the news organizations that housed them, which cohered into institutions. But journalism has been newly problematized, destabilizing and restructuring both the units and levels of analysis in journalism theorizing. The networked public sphere is constituted with new assemblages: of newswork, institutional arrangements, and global connections, which give rise to new emerging deliberative spaces. Journalism theories now have as much interest in process as product, in assemblage as outcome, but still need to be concerned with the nature of quality of these spaces. What shape do they take on and with what implications for healthy democratic discourse?

Humans live not only in a physical world but also in a mental world. Theory of mind reflects the understanding that the mind is comprised of different mental states, such as intentions, desires, and beliefs. This conception of the mind is a critical achievement in human development because it directly impacts effective communication and social interaction. It allows for the understanding of others’ behaviors by inferring their mental states. The formation of a theory of mind has been a central topic in psychology, neuroscience, cognitive science, and philosophy. It impacts related processes, such as communication skills, perspective-taking ability, and social cognition.
Across the life span, the understanding of the mind becomes increasingly complex. Early in development, infants and toddlers can discern the intentions of others. Later, more sophisticated reasoning about the mental states of others becomes possible. For instance, the ability to follow and understand the recursive thought that “Sam believes, that Mary said, that Jose wanted . . .” develops. Additionally, within distinctive developmental time periods, people differ in their ability to take into account mental states. Once people’s beliefs, including their misconceptions, are identified, it is possible to generate effective communication strategies designed to teach, learn, and even reduce risk-taking behaviors.

Social psychological research on thinking has generally focused on the attitudes, emotions, motivations, and biases that affect thinking and consequent behavior. What has received less attention is the speed of thinking: how quickly thinking occurs and whether thoughts accelerate or slow down. Communication design and processing may take for granted that the structure and reception of messages occur at a certain speed. Recent findings from the psychological study of thought speed shed light on ways that this research may be applied to health communication. Fast and slow rates of thinking are correlated with distinct patterns of affective, cognitive, physiological, and behavioral events. Fast thinking is associated with positive mood, energy, approach motivation, arousal, creativity, and risk-taking. Slow thinking is associated with negative mood and depression, low energy, and cognitive impairment. Potential theories exist for why psychological and physiological experiences are associated with thought speed.
Recent experimental research demonstrates that thought speed can be successfully manipulated to elicit psychological effects, and it can be manipulated independent of thought content. Researchers, healthcare practitioners, and communicators should be aware of the psychological correlates and consequences of thought speed and consider harnessing the effects of thought speed to augment communication. Thought acceleration and deceleration can be integrated into the design and processing of health communication.

Tourism connects people across geographical, chronological, and cultural borders. In Henri Tajfel’s terms, it is a prime example of intergroup process where collective and interpersonal factors play major roles. People become tourists to fulfill their self-derived motivations, including sensation-, novelty-, and pleasure-seeking, or even good will. Their motivations to travel are influenced by group-related factors, such as media portrayals of the destination and the sense of connectedness to the place of visit. Moreover, contextual variables, such as the presence of diplomatic relations or the level of peace and security, should indicate whether the borders are permeable and open to the tourists, and if the destination is accessible as a viable option for them to visit. Needless to say, simply wanting to be different from one’s everyday selves or desiring to be in a different environment are legitimate reasons for one to be a tourist.
Tourists have contact with other people at various phases of their travel to and from their destinations. Through contact, tourists as guests communicate with their hosts, who are local residents of the destination and tourism-related service providers. Guest-host contact often takes place in limited contexts, and tends to be fleeting, non-intimate, and power-structured, often cast in a “they-us” frame. However, such contact can ultimately bring important social consequences to the tourists and to the destination.
Communication accommodation holds an important key to some of the major outcomes of host-guest contact. Accommodation involves adjustment of one’s linguistic and non-linguistic behaviors during communication for smooth interaction and social approval from others. Successful contact through accommodation can bring positive outcomes to the communicators such as an increase in positive attitudes toward the other and advances in intercultural communication competence, while exploitation, deception, and maintenance of power-differentiated relations are also likely associated with communication accommodation. Likewise, contact between tourists and local residents has potential to contribute to long-term changes in the macro cultural milieu of the destination, including the resurgence or erosion of the traditional culture and languages, increased presence of foreign languages, and building of peaceful relationships between societies, all of which in turn become precursors to the further development of tourism.

The transcription system for Conversation Analysis (CA) was originally developed by Gail Jefferson, one of the founders of CA, in the 1960s. Jefferson’s transcription conventions aim to represent on paper what had been captured in field audio recordings in ways that would preserve and bring to light the interactionally relevant elements of the recorded talk. Conversation analytic research has demonstrated that various features of the delivery of talk and other bodily conduct are basic to how interlocutors carry out social actions in interaction with others. Without the CA transcription system it is impossible to identify these features, as it represents talk and other conduct in ways that capture the rich subtlety of their delivery. Jefferson’s system of conventions evolved side by side with, and was informed by the results of, interaction analysis, which has shown there are many significant aspects of talk that interactants treat as relevant but that are entirely missed in simple orthographic representation.
Conversation analysts’ insistence on capturing not only what is said but also details of how something is said, including interactants’ visible behaviors, is based on the assumption that “no order of detail in interaction can be dismissed a priori as disorderly, accidental, or irrelevant” (according to John Heritage in 1984). Conversation analytic transcripts need to be detailed enough to facilitate the analyst’s quest to discover and describe orderly practices of social action in interaction.

Transportation Theory: Narrative transportation theory focuses on the causes and consequences of an individual being immersed in a story, or transported into a narrative world. Transportation refers to the feeling of being so absorbed in a story that connection to the real world is lost for some time; it includes cognitive engagement, emotional experience, and the presence of mental imagery. This experience is a key mechanism underlying narrative influence on recipients’ attitudes and beliefs, particularly in combination with enjoyment and character identification. Narrative persuasion through transportation has been demonstrated with a wide variety of topics, including health, social issues, and consumer products. Transportation can occur across media (through written, audio, or video narratives) and for both factual and fictional stories. It is typically measured with a self-report scale, which has been well-validated (Green & Brock, 2000). Transportation is conceptually similar to flow (Csikszentmihalyi, 1990) and presence (Klimmt & Vorderer, 2003), although both flow and presence pertain more to being immersed in an experience, rather than specifically in a narrative. While individuals are transported, their mental systems and capacities become concentrated on events occurring in the story, causing them to lose track of time, lack awareness of the surrounding environment, and experience powerful emotions as a result of their immersion in the narrative. Transported recipients may also lose some access to real-world knowledge, making them more likely to adapt their real-world beliefs and behaviors to be more consistent with the story to which they are exposed. Transportation theory suggests several mechanisms to explain this phenomenon, including reduced counterarguing, connections with characters, heightened perceptions of realism, the formation of vivid mental imagery, and emotional engagement. Personality factors can also affect the extent of transportation: narrative recipients vary in transportability, or their dispositional tendency to become transported; and they may be influenced differently by narratives due to a difference in their need for affect (individuals high in need for affect are more likely to be transported into narratives). Additional factors such as story quality and points of similarity between the reader and the story can also influence transportation.

The Transtheoretical Model (TTM) is an integrative health behavior change theory that describes the process of how people change their behavior. The central organizing construct in the theory is stages of change, which are five distinct stages of readiness to change behavior, ranging from not ready to change (precontemplation), thinking about change (contemplation), preparing to change (preparation), changing (action), and maintaining the change (maintenance). Movement through the stages may be nonlinear, and cycling and recycling through the stages is viewed as a natural part of the change process. Other model constructs explain what drives individuals forward through the stages of change. Decisional balance involves a weighing of pros and cons of changing behavior, while self-efficacy involves situation-specific confidence that one can change. Increases in pros, deceases in cons, and increases in self-efficacy propel people forward through the stages of change. The processes of change are experiential and behavioral strategies that people use to change their behavior. In early stages of change, people use experiential strategies while they use behaviorally oriented strategies in later stages of change. The TTM holds significant implications for message design. Most notably, messages should be targeted and tailored to stages of change, and where possible, to other model variables as well. Studies indicate that the TTM has been successfully applied to health communication campaigns, and to a larger extent, to computer-tailored interventions to change health behavior. Meta-analyses indicate that scores of computer-tailored interventions have been efficacious, including many based upon the TTM and stages of change. New applications of the model include a focus on novel health behaviors, multiple behavior change, and advancing an understanding of message design in the context of the TTM in combination with other theoretical approaches.

Explanations designed to teach, rather than to support scientific claims in scholarly works, are essential in health and risk communication. Patients explain why they think their symptoms warrant medical attention. Clinicians elicit information from patients and explain diagnoses and treatments. Families and friends explain health and risk concerns to one another. In addition, there are websites, brochures, fact sheets, museum exhibits, health fairs, and news stories explaining health and risk to lay audiences. Unfortunately, research on this important discursive goal is less extensive than is research on persuasion, that is, efforts to gain agreement. One problem is that explanation-as-teaching has not been carefully conceptualized. Some confuse this communication goal and discursive type with its frequent verbal and visual features, such as simple wording or diagrams. Others believe explanation-as-teaching does not exist as a distinctive communication goal, maintaining that all communication is solely persuasive: that is, designed to gain agreement.
Explanation-as-teaching is a distinct and important health communication goal. Patient involvement in decision making requires that both clinicians and patients understand options underlying health-care choices. To explore types of explanation-as-teaching, research provides (a) several ways of categorizing health and risk explanations for lay audiences; (b) evidence that certain textual and graphic features overcome predictable confusions, and (c) illustrations of each explanation type. Additionally, explanation types succeed or fail in part because of the social or emotional conditions in which they are presented so it is important to note research on conditions that support patients, families, and clinicians in benefiting from explanations of health and risk complexities and curricula designed to enhance clinicians’ explanatory skill.
Uncertainty regarding the self—about who we are, our place in the world, and our future is typically an unsettling and aversive state. It is a state that we are motivated to reduce in order to gain predictability over events in the world around us. One of the most effective ways of managing uncertainty regarding the self is by seeking group memberships and belonging to groups. Thus, uncertainty reduction can be construed as a drive, such that we join and identify with groups in order to manage uncertainty about and related to the self; this is the core tenet of uncertainty-identity theory, which discusses uncertainty reduction as one of the motives for seeking group memberships.
Previous work in uncertainty-identity theory has shown that when uncertain about the self, individuals seek highly entitative groups to identify with. Such groups are characterized by clear, distinct boundaries—a clear sense of what the group stands for while spelling out who we are versus who we are not. Highly entitative groups have interdependent members and a clear sense of identity that is distinct from those of other groups. According to uncertainty-identity theory, identifying with such groups can reduce self-uncertainty, as individuals can define the self in terms of a clear, distinct prototype and manage uncertainty regarding who they are. Research in uncertainty-identity theory shows that when uncertain, group members perceptually polarize their group away from the outgroup in order to enhance the perceived entitativity and distinctiveness of their group prototype relative to other groups. Thus, the group moves to an extreme and polarized position that is far removed from that of an outgroup with the need to fashion a distinctive identity. The preference for a clearly defined and highly entitative social identity that helps delineate who we are versus who we are not when group members are self-uncertain should increase group members’ vulnerability to ingroup rhetoric that emphasizes the distinctiveness of group boundaries and an us versus them thinking. This is a dangerous trend, especially in the context of intergroup conflict, as influential group members, such as leaders, might seek to mobilize group members by demonizing outgroup members while attributing suffering and unpredictability experienced by ingroup members to the actions of outgroup members. Thus, gaining an understanding of the processes through which the uncertainty of group members is exploited to mobilize support for extreme ideologies might be one way to explain extremism and radical behavior by groups.
