Food is a primary biological motivator and elicits automatic approach and consumption responses. How directly food is portrayed may alter these responses and, as a result, influence how food ads, brands and products are evaluated. This paper presents two experiments that examine how the portrayal of food in food advertisements can alter its motivational appeal, and as such, alter dynamic appetitive responses and later evaluations. The ads in this study differed in how they were produced. Some ads initially portrayed food as very appetizing and ready-to-eat while others initially portrayed foods in their packaging and not ready-to-eat. In general, results support that unpackaged food is more directly appetitive, showing better physiological appetitive responses and better attitudinal evaluations overall.

Extensive research demonstrates that exposure to threatening anti-tobacco messages can lead to defensive message processing which reduces message effectiveness. However, research investigating whether this effect is moderated by the smoking status of the message viewer is lacking. In this study, participants (N = 48 smokers and N = 51 non-smokers) viewed and rated secondhand smoke anti-tobacco messages depicting both smoking cues and threat content, or messages depicting neither while heart rate, skin conductance, and facial EMG were recorded. Post viewing, self-reported emotional experience, level of counterarguing, and recognition memory were measured. In support of the LC4MP, there were no differences between smokers and non-smokers’ responses for non-threatening messages absent in smoking cues. However, messages that contained both smoking cues and threat content were defensively processed by smokers – but not non-smokers – as indicated by significantly faster heart rate, lower recognition memory and higher self-reported negativity, arousal, and counterarguments. The theoretical and practical implications are discussed.

From an ecological perception perspective (Gibson, 1977), the availability of perceptual information alters what behaviors are more and less likely at different times. This study examines how perceptual information delivered in food advertisements and packaging alters the time course of information processing and decision making. Participants categorized images of food that varied in information delivered in terms of color, glossiness, and texture (e.g., food cues) before and after being exposed to a set of advertisements that also varied in this way. In general, items with more direct cues enhanced appetitive motivational processes, especially if they were also advertised with direct food cues. Individuals also chose to eat products that were packaged with more available direct food cues compared to opaque packaging.

This study examined individuals’ physiological and cognitive responses to different types of emotionally experienced content located in obesity prevention fear appeals. Results suggested that experienced valence impacted individuals’ attention and memory as a function of experienced arousal level. Local content that created coactive highly arousing experiences received the most attention, though visual recognition suggested these messages were more difficult to encode. Local content that created negative moderately arousing experiences was best encoded. Global message evaluation data suggest that moderately arousing messages with a change in experienced valence may prove to be most effective, as they ensure attention and good memory while keeping high self-reported interest, and a high level of perceived severity of obesity. Implications and suggestions for future research are discussed.

The implementation of body-worn cameras (BWC) by policing agencies has received widespread support from many individuals, including citizens and police officers. Despite their increasing prevalence, little is known about how the point-of-view (POV) of these cameras affects perceptions of viewers. In this research, we investigate how POV interacts with skin color of citizens in police use of force videos to affect perceptions of procedural justice. In an experimental study, participants watched eight police use of force videos—half recorded from BWC and half from an onlooker’s perspective—in which skin tone of the citizen varied. Results indicate that POV interacts with citizen skin tone such that, compared to the onlooker perspective, the BWC exacerbated viewer racial bias against dark skin tone citizens. Furthermore, identification with the police officer fully mediated this relationship. Results are discussed in relation to media theory and practical implications.
