The reasoned action approach is a behavioral theory that has been developed since the 1960s in a sequence of reformulations. It comprises the theory of reasoned action; the theory of planned behavior; the integrative model of behavioral prediction; and its current formulation, the reasoned action approach to explaining and changing behavior. Applied to health messages, reasoned action theory proposes a behavioral process that can be described in terms of four parts. First, together with a multitude of other potential sources, health messages are a source of beliefs about outcomes of a particular health behavior, about the extent of social support for performing that behavior from specific other people, and about factors that may hamper or facilitate engaging in the behavior. Second, these beliefs inform attitude toward performing the behavior, perceptions of normative influence, and perceptions of control with respect to performing the behavior. Third, attitude, perceived norms, and perceived control inform the intention to perform the behavior. Fourth, people will act on their intention if they have the required skills to do so and if there are no environmental obstacles that impede behavioral performance. The theory’s conceptual perspective on beliefs as the foundation of behavior offers a theoretical understanding of the role of health messages in behavior change. The theory also can be used as a practical tool for identifying those beliefs that may be most promising to address in health messages, which makes the theory useful for those designing health message interventions. Reasoned action theory is one of the most widely used theories in health behavior research and health intervention design, yet is not without its critics. Some critiques appear to be misconceptions, such as the incorrect contention that reasoned action theory is a theory of rational, deliberative decision making. Others are justified, such as the concern that the theory does not generate testable hypotheses about when which variable is most likely to predict a particular behavior.

Racial stereotypes flood today’s mass media. Researchers investigate these stereotypes’ prevalence, from news to entertainment. Black and Latino stereotypes draw particular concern, especially because they misrepresent these racial groups. From both psychological and sociological perspectives, these misrepresentations can influence how people view their racial group as well as other groups. Furthermore, a racial group’s lack of representation can also reduce the group’s visibility to the general public. Such is the case for Native Americans and Asian Americans. Given mass media’s widespread distribution of black and Latino stereotypes, most research on mediated racial portrayals focuses on these two groups. For instance, while black actors and actresses appear often in prime-time televisions shows, black women appear more often in situational comedies than any other genre. Also, when compared to white actors and actresses, television casts blacks in villainous or despicable roles at a higher rate. In advertising, black women often display Eurocentric features, like straight hair. On the other hand, black men are cast as unemployed, athletic, or entertainers. In sports entertainment, journalists emphasize white athletes’ intelligence and black athletes’ athleticism. In music videos, black men appear threatening and sport dark skin tones. These music videos also sexualize black women and tend to emphasize those with light skin tones. News media overrepresent black criminality and exaggerate the notion that blacks belong to the undeserving poor class. Video games tend to portray black characters as either violent outlaws or athletic. While mass media misrepresent the black population, it tends to both misrepresent and underrepresent the Latino population. When represented in entertainment media, Latinos assume hypersexualized roles and low-occupation jobs. Both news and entertainment media overrepresent Latino criminality. News outlets also overly associate Latino immigration with crime and relate Latino immigration to economic threat. Video games rarely portray Latino characters. Creators may create stereotypic content or fail to fairly represent racial and ethnic groups for a few reasons. First, the ethnic blame discourse in the United States may influence creators’ conscious and unconscious decision-making processes. This discourse contends that the ethnic and racial minorities are responsible for their own problems. Second, since stereotypes appeal to and are easily processed by large general audiences, the misrepresentation of racial and ethnic groups facilitates revenue generation. This article largely discusses media representations of blacks and Latinos and explains the implications of such portrayals.

People use the news media to learn about the world beyond their family, neighborhood, and workplace. As news consumers, we depend on what television, social media, websites, radio stations, and newspapers decide to inform us about. This is because all news media, whether through journalists or digital algorithms, select, process, and filter information to their users. Over time, the aspects that are prominent in the news media usually become prominent in public opinion. The ability of journalists to influence which issues, aspects of these issues, and persons related to these issues, are perceived as the most salient has come to be called the agenda-setting effect of journalism. First described by Maxwell McCombs and Donald Shaw in a seminal study conducted during the 1968 elections in the United States, agenda-setting theory has expanded to include several other aspects beyond the transfer of salience of issues from the media agenda to the public agenda. These aspects include: the influence of journalism on the attributes of issues and people that make news; the networks between the different elements in the media and public agendas; the determinants of the news media agenda; the psychological mechanisms that regulate agenda-setting effects; and the consequences of agenda setting on both citizens’ and policymakers’ attitudes and behaviors. As one of the most comprehensive and international theories of journalism studies available, agenda setting continues to evolve in the expanding digital media landscape.
