Message sensation value (MSV) is defined as the degree to which a message’s format and content features elicit sensory, affective, and arousal responses. MSV research has received considerable scholarly and professional attention for more than two decades. The seminal work, to date, has been conducted by the Kentucky School. MSV was initially operationalized as perceived message sensation value (PMSV). The activation model of information exposure (AMIE) provides the basis for explaining the functional mechanism of MSV and PMSV. The AMIE proposes that exposure is a function of the interaction between an individual’s sensation-seeking tendency and sensation-enhancing attributes of the message itself. There are three primary types of message features that contribute to MSV: (a) the formal video dimension, (b) the formal audio dimension, and (c) the content dimension. There is an important distinction between subjective reactions to the message (PMSV) and the format and content features contributing to these reactions (MSV). In general, messages of high relative to low in sensation value have elicited greater message processing and more favorable evaluations across a range of outcome variables in health communication. Some health communication campaigns have employed high sensation value messages to target high sensation seekers. This sensation-seeking targeting approach, SENTAR, however, has received mixed and limited support. The influence of MSV on message effectiveness might be very similar for the two groups. Recently, some scholars have attempted to situate AMIE in a broader context of persuasion. First, AMIE and the elaboration likelihood model (ELM) offer competing predictions in terms of the role of MSV in persuasion, such that AMIE stresses a straightforward attention-getting effect, whereas ELM predicts a distracting effect of MSV interfering with message’s content. The very few studies conducted thus far reveal limited and mixed findings. Second, in the integration of MSV research with the appraisal theory and excitation-transfer theory, MSV may function as an arousal generator to amplify the influence of discrete emotions on perceived message effectiveness. Third, according to the psychological reactance theory, there are challenges with implementing high sensation value (HSV) messages, in that they potentially could backfire among the target audiences. Messages with HSV may garner better-perceived effectiveness when they tone down the controlling language. Future studies should investigate the relationships between specific MSV-enhancing features and message processing. They can expand the literature by studying the impact of MSV in a variety of media message contexts (e.g., broadcast journalism). Future experiments might also incorporate psychophysiological measures (e.g., skin response and heart-rate deceleration) to complement self-reported measures. Future studies should continue to explore other features (e.g., visual-verbal redundancy) that might affect attention and message processing jointly with MSV, and other individual difference variables, such as need for cognition, trait reactance, locus of control, and etc.

Sensation seeking is a biologically based personality trait that is characterized by the need to seek a variety of sensations and experiences and the willingness to take risks to achieve them. There is a large volume of literature on sensation seeking that delineates important conceptual and operational distinctions, including several prominent measures of sensation seeking. Issues related to research design and data analysis include whether researchers treat sensation seeking as an independent or dependent variable, use total scale versus subscale scores in analyses, treat scores as continuous or grouped variables, and consider demographic variables in their analyses. Research may relate sensation seeking to a range of behaviors, from maladaptive behaviors such as substance use and risky sex to more neutral or even adaptive behaviors such as preferences for music and art or preferences for certain careers. Research may establish a genetic basis for sensation seeking and/or associate sensation seeking with neurological and physiological responsiveness. Research also explores the associations of sensation seeking to perceptions of risk, as well as the sex and age of individuals and groups in an international context.

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.

Affect has historically been conceptualized in one of two dominant ways. The first perspective, which has its roots in psychology and neuroscience, tends to view affect as an elemental state. This tradition is reflected in Silvan S. Tomkins’s theory of primary affects and Antonio Damasio’s theory of basic emotions. Recent extensions of this tradition include the work of Eve Kosofsky Sedgwick, Lisa Cartwright, and Teresa Brennan. The second perspective, which is typically associated with developments in philosophy and the humanities, treats affect as an intensive force. This tradition, whose most famous proponent is Gilles Deleuze, is evident in Brian Massumi’s theory of autonomous affect and Nigel Thrift’s non-representational theory. Recent extensions of this tradition tend to emphasize the importance of materiality, or what Jane Bennett has called “thing-power.” A number of scholars working in communication and cultural studies have created a third, hybrid tradition that attempts to bridge or mediate the two dominant historical accounts. This third perspective includes Lawrence Grossberg’s notion of affective investments, Christian Lundberg’s Lacanian-inspired view of affect, Sara Ahmed’s work on the sociality of emotion, and Gernot Böhme’s theory of atmospheres.
