Authority defied: need for cognitive closure influences regulatory control when resisting authority.

The present studies examined whether differences in need for cognitive closure (NCC) were related to differences in regulatory control when confronted with authority. In two studies, levels of regulatory control were measured when participants resisted (Study 1; N = 46) or prepared to resist the influence attempt of an authority figure (Study 2; N = 50). Results showed that resisting the influence attempt from a high-authority figure was more depleting for participants higher in NCC compared to individuals lower in NCC. However, when they were given instructions and time to prepare the act of resistance, individuals high in NCC actually showed an increase in regulatory control. Authority is usually viewed as a general principle of influence; however, the present studies suggest that there are individual differences that influence how people may experience interactions with authorities.

Assessment of implicit sexual associations in non-incarcerated pedophiles.

Offences committed by pedophiles are crimes that evoke serious public concern and outrage. Although recent research using implicit measures has shown promise in detecting deviant sexual associations, the discriminatory and predictive quality of implicit tasks has not yet surpassed traditional assessment methods such as questionnaires and phallometry. The current research extended previous findings by examining whether a combination of two implicit tasks, the Implicit Association Task (IAT) and the Picture Association Task (PAT), was capable of differentiating pedophiles from non-pedophiles, and whether the PAT, which allows separate analysis for male, female, boy and girl stimulus categories, was more sensitive to specific sexual associations in pedophiles than the IAT. A total of 20 male self-reported pedophiles (10 offender and 10 non-offenders) and 20 male self-reported heterosexual controls completed the two implicit measures. Results indicated that the combination of both tasks produced the strongest results to date in detecting implicit pedophilic preferences (AUC = .97). Additionally, the PAT showed promise in decomposing the sexual associations in pedophiles. Interestingly, as there was an equal distribution of offenders and non-offenders in the pedophile group, it was possible to test for implicit association differences between these groups. This comparison showed no clear link between having these implicit sexual associations and actual offending.

Empathy is a beautiful thing: empathy predicts imitation only for attractive others.

Research shows that we spontaneously imitate people. Moreover, empathy predicts the degree of this non-conscious imitation. Little is known, however, if or how this expression of empathy is influenced by stable physical characteristics of our interaction-partners. In two studies, we tested whether attractiveness of others moderated the relation between empathy and imitation. While seeing a woman performing joystick movements, participants either imitated, or non-imitated these movements. Results showed that the higher participants empathy score, the faster they imitated an attractive person. The level of empathy did not predict the degree of imitation of unattractive targets. The findings demonstrate that the expression of empathy through imitation can be moderated by attractiveness, thereby introducing a new dimension to the conditionality of empathy.

Good morning creativity: task reactivation during sleep enhances beneficial effect of sleep on creative performance.

Both scientists and artists have suggested that sleep facilitates creativity, and this idea has received substantial empirical support. In the current study, we investigate whether one can actively enhance the beneficial effect of sleep on creativity by covertly reactivating the creativity task during sleep. Individuals' creative performance was compared after three different conditions: sleep-with-conditioned-odor; sleep-with-control-odor; or sleep-with-no-odor. In the evening prior to sleep, all participants were presented with a problem that required a creative solution. In the two odor conditions, a hidden scent-diffuser spread an odor while the problem was presented. In the sleep-with-conditioned-odor condition, task reactivation during sleep was induced by means of the odor that was also presented while participants were informed about the problem. In the sleep-with-control-odor condition, participants were exposed to a different odor during sleep than the one diffused during problem presentation. In the no odor condition, no odor was presented. After a night of sleep with the conditioned odor, participants were found to be: (i) more creative; and (ii) better able to select their most creative idea than participants who had been exposed to a control odor or no odor while sleeping. These findings suggest that we do not have to passively wait until we are hit by our creative muse while sleeping. Task reactivation during sleep can actively trigger creativity-related processes during sleep and thereby boost the beneficial effect of sleep on creativity.

Prosocial consequences of imitation.

Research has shown that helping behavior can be primed easily. However, helping decreases significantly in the presence of inhibition cues, signaling high costs for the executor. On the other hand, multiple studies demonstrated that helping behavior increases after being mimicked. The present study investigated whether imitation still increases helping when more substantial costs are involved. Helping behavior was operationalized as the willingness to accompany the confederate on a 15-20 minute walk to the train station. Results show that even in the face of these high costs, participants who were mimicked agreed more often to help the confederate than participants who were anti-mimicked. These findings suggest that mimicry not only makes people more helpful when it comes to small favors, but also allows them to ignore the substantial costs possibly involved in helping others.

The influence of culture and close others on the effectiveness of (self)-persuasion.

Although self-persuasion was shown to be more effective than direct persuasion in changing attitudes and intentions, its effectiveness in different cultures remains unclear. Furthermore, research suggests that Eastern individuals tend to incorporate close others in the self to a larger extent than Western individuals. Combining both lines of research, the current studies examined whether thinking of a close other would influence the effectiveness of (self)-persuasion across cultures. Two parallel studies were conducted. U.S. participants (nstudy 1 = 195; nstudy 2 = 292) and Chinese participants (nstudy 1 = 187; nstudy 2 = 313) reported their initial attitudes and intentions toward five target behaviors prior to either think of a specific close other or not. Subsequently, they were randomly assigned to receive either a self-persuasion or a direct persuasion task. Specifically, the self-persuasion task led participants to generate own arguments or arguments that they think the close other would give; the direct persuasion task led participants to read given arguments or imagine that the arguments were from the close other. In the end, all participants reported their attitudes and intentions again after doing the persuasion tasks. The moderation effect of culture was only found in Study 1, such that direct persuasion worked more effectively in Chinese participants than self-persuasion, whereas the effectiveness of the two persuasive techniques did not differ in U.S. participants. In both studies, thinking of a close other was not found to influence the effectiveness of (self-)persuasion across cultures. Possible explanations and future research directions were discussed.

Perspective taking eliminates differences in co-representation of out-group members' actions.

Coordinated action relies on shared representations between interaction partners: people co-represent actions of others in order to respond appropriately. However, little is known about the social factors that influence shared representations. We investigated whether actions performed by in-group and out-group members are represented differently, and if so, what role perspective-taking plays in this process. White participants performed a joint Simon task with an animated image of a hand with either white or black skin tone. Results of study I demonstrated that actions performed by in-group members were co-represented while actions of out-group members were not. In study II, it was found that participants co-represented actions of out-group members when they had read about an out-group member and to take his perspective prior to the actual experiment. Possible explanations for these findings are discussed.

Do we act upon what we see? Direct effects of alcohol cues in movies on young adults' alcohol drinking.

AIMS: Ample survey research has shown that alcohol portrayals in movies affect the development of alcohol consumption in youth. Hence, there is preliminary evidence that alcohol portrayals in movies also directly influence viewers' drinking of alcohol while watching movies. One process that might account for these direct effects is imitation. The present study therefore examined whether young people imitate actors sipping alcohol on screen. METHODS: We observed sipping behaviours of 79 young adults (ages 18-25) watching a 60-min movie clip, 'What Happens in Vegas', in a semi-naturalistic home setting. Each of the 79 participants was exposed to 25 alcohol cues. Two-level logistic regression analyses were used to analyse whether participants in general imitated actors' sipping during this clip. In addition, we applied proportional hazard models in a survival analysis framework (Cox regression) to test whether there was a difference in imitation of the cues between male and female participants, and to test whether the timing of the actors' sipping throughout the movie played a role. RESULTS: The findings showed that participants were more likely to sip in accordance with the actors' sipping than without such a cue. Further, we found that men were more likely to imitate actors' sipping than females and that participants tended to respond to actors' sipping at the beginning of the movie rather than at the end. CONCLUSION: Exposure to actors sipping alcohol in a movie seems to have an immediate impact on the drinking behaviour of viewers, via the mechanism of imitation.

Unconscious-thought effects take place off-line, not on-line.

The unconscious-thought effect refers to an improvement in decision making following distraction from the decision context for a period of time. The dominant explanation for this effect is that unconscious processes continue to deal with the problem during the distraction period. Recently, however, some researchers have proposed that unconscious thinkers may be merely recalling a judgment that was formed on-line (i.e., during information acquisition). We present two experiments that rule out the latter interpretation. In the unconscious-thought condition of the first experiment, participants who reported making their decision after unconscious thought made better decisions than those who reported making their decision on-line. In the second experiment, all participants judged the choice alternatives both on-line and off-line. On-line judgments were predictive of off-line judgments only in the immediate-decision condition, but not in the conscious- and unconscious-thought conditions. These results demonstrate that a period of unconscious thought does improve judgments that were formed earlier on-line.

Exposure to movie smoking, antismoking ads and smoking intensity: an experimental study with a factorial design.

BACKGROUND: This study examines whether smoking portrayal in movies or antismoking advertisements affect smoking intensity among young adults. METHODS: We conducted an experimental study in which 84 smokers were randomly assigned using a two (no-smoking versus smoking portrayal in the movie) by three (two prosocial ads, two antismoking ads or one of each) factorial design. Participants viewed a 60-minute movie with two commercial breaks and afterwards completed a questionnaire. Smoking during the session was allowed and observed. RESULTS: Exposure to the movie with smoking had no effect on smoking intensity. Those who viewed two antismoking ads had significantly lower smoking intensity compared with those who viewed two prosocial ads. There was no interaction between movie smoking and antismoking ads. Baseline CO (carbon monoxide) level had the largest effect on smoking intensity. CONCLUSION: These findings provide further evidence to support antismoking ads placed with movies because of their possible effect on young adult smoking behaviour. However, caution is warranted, because nicotine dependence appears to be the primary predictor of smoking intensity among young adult smokers in this study.

Exposure to soda commercials affects sugar-sweetened soda consumption in young women. An observational experimental study.

The present study examines the direct effects of television commercials advertising soda on actual sugar-sweetened soda consumption among young women. An experimental-observational study design was used, in which 51 female students (ages 18-29) were exposed to a 35-min movie clip, interrupted by two commercial breaks consisting of soda or water commercials. Their actual soda consumption while watching the movie clip was examined. An analysis of variance was used to examine the effects of commercial condition on soda consumption. Thirst and first glass consumed before the first commercial break were added as covariates in the analyses. Results indicated that participants assigned to the condition with soda commercials consumed 1.3 ounces more soda than participants in the water commercial condition. Exposure to soda commercials while watching a movie can have a strong influence on increasing sugar-sweetened soda consumption in young women.

Time for Action: Verbal Action Cues Influence Temporal Binding.

Prior research has shown that our perception of time is compressed when we volitionally perform actions, a phenomenon referred to as temporal binding. In three studies, we investigated the degree to which contextual cues that signaled other agents and related to actions would influence binding, given that those cues may affect individual's feelings of independent action performance. Participants heard action verbalizations that did or did not match actions that participants had already begun performing. Participants' time estimates of the intervals between action initiations and action effects were higher on trials in which they heard verbalizations that matched their ongoing actions, and lower on trials in which the verbalizations and actions did not match. Such effects did not occur when participants passively observed actions and effects being caused by the computer. These results show that the compatibility of action cues with ongoing actions influences temporal binding effects, suggesting that they influence our feelings of having been an independent agent.

Predicting soccer matches after unconscious and conscious thought as a function of expertise.

In two experiments, we investigated the effects of expertise and mode of thought on the accuracy of people's predictions. Both experts and nonexperts predicted the results of soccer matches after conscious thought, after unconscious thought, or immediately. In Experiment 1, experts who thought unconsciously outperformed participants in all other conditions. Whereas unconscious thinkers showed a correlation between expertise and accuracy of prediction, no such relation was observed for conscious thinkers or for immediate decision makers. In Experiment 2, this general pattern was replicated. In addition, experts who thought unconsciously were better at applying diagnostic information than experts who thought consciously or who decided immediately. The results are consistent with unconscious-thought theory.

Finding comfort in a joke: consolatory effects of humor through cognitive distraction.

This study aimed to demonstrate that the cognitive demands involved in humor processing can attenuate negative emotions. A primary aspect of humor is that it poses cognitive demands needed for incongruency resolution. On the basis of findings that cognitive distraction prevents mood-congruent processing, the authors hypothesized that humorous stimuli attenuate negative emotions to a greater extent than do equally positive nonhumorous stimuli. To test this idea, the authors used a modified version of the picture-viewing paradigm of L. F. Van Dillen and S. L. Koole (2007). Participants viewed neutral, mildly negative, and strongly negative pictures, followed by either a humorous or an equally positive nonhumorous stimulus, and then rated their feelings. Participants reported less negative feelings in both mildly and strongly negative trials with humorous positive stimuli than with nonhumorous positive stimuli. Humor did not differentially affect emotions in the neutral trials. Stimuli that posed greater cognitive demands were more effective in regulating negative emotions than less demanding stimuli. These findings fully support Van Dillen and Koole's working memory model of distraction from negative mood and suggest that humor may attenuate negative emotions as a result of cognitive distraction.

Alcohol portrayal on television affects actual drinking behaviour.

AIMS: Alcohol portrayal in movies and commercials is generally positive and might stimulate young people to drink. We tested experimentally whether portrayal of alcohol images in movies and commercials on television promotes actual drinking. METHODS: In a naturalistic setting (a bar lab), young adult male pairs watched a movie clip for 1 h with two commercial breaks and were allowed to drink non-alcohol and alcoholic beverages. These participants were randomly assigned to one of four conditions varying on the type of movie (many versus few alcohol portrayals) and commercials (alcohol commercials present or not). RESULTS: Participants assigned to the conditions with substantial alcohol exposure in either movies or commercials consume more alcohol than other participants. Those in the condition with alcohol portrayal in movie and commercials drank on average 1.5 glasses more than those in the condition with no alcohol portrayal, within a period of 1 h. CONCLUSIONS: This study-for the first time-shows a causal link between exposure to drinking models and alcohol commercials on acute alcohol consumption.

Humor in advertisements enhances product liking by mere association.

Humor in advertising is known to enhance product liking, but this attitude change is often considered nonpredictive of product choice. Previous research relied exclusively on explicit self-report measures to assess attitudes and purchase intentions. The present research shows that unobtrusive association of a product with humor can affect persuasion through implicit attitude change. Participants viewed humorous and nonhumorous cartoons in a mock-up magazine. One of two products was consistently presented in the vicinity of the humorous cartoons, whereas the other product was consistently presented in the vicinity of the nonhumorous cartoons. The results of an evaluative priming task showed enhanced evaluations of products paired with humor (Experiment 1, 2, and 3). Furthermore, these enhanced evaluations mediated the relation between association with humor and product choice (Experiment 2 and 3). Paradoxically, products paired with humor were also less recognized than the control products (Experiments 2 and 3). In summary, the present research demonstrates that mere association with humor enhances product evaluations and product choice in a way that is dissociated from the accessibility of the product in memory.

Quick question or intensive inquiry: The role of message elaboration in the effectiveness of self-persuasive anti-alcohol posters.

Self-persuasion (i.e., generating your own arguments) is often more persuasive than direct persuasion (i.e., being provided with arguments), even when the technique is applied in media messages by framing the message as a question. It is unclear, however, if these messages are more persuasive when viewed for a long period to allow more elaboration about the message, or for a short period to reduce elaboration. In the current experiment, this is addressed by examining whether anti-alcohol posters framed as a statement (direct persuasion) or an open-ended question (self-persuasion) are more effective to reduce alcohol consumption under conditions of short- or long message exposure, compared to a control condition (no poster). Additionally, the potentially moderating roles of self-perceived alcohol identity and self-esteem on both types of persuasion are examined. Participants (N = 149) were exposed to a self-persuasion or direct persuasion anti-alcohol poster, either briefly before or continuously during a bogus beer taste task. The amount of alcohol consumed was the covert dependent variable. Contrary to expectations, both posters failed to affect alcohol consumption, regardless of exposure length. No moderation effects for self-perceived alcohol identity and self-esteem of the participants were found. Possible explanations are discussed.

Self-persuasion in media messages: Reducing alcohol consumption among students with open-ended questions.

Self-persuasion (self-generation of arguments) is often a more effective influence technique than direct persuasion (providing arguments). However, the application of this technique in health media communications has received limited attention. In two experiments, it was examined whether self-persuasion can be successfully applied to antialcohol media communications by framing the message as an open-ended question. In Experiment 1 (N = 131) cognitive reactions to antialcohol posters framed either as open-ended questions or statements were examined. In Experiment 2 (N = 122) the effectiveness of this framing to reduce actual alcohol consumption was tested. Experiment 1 demonstrated that exposure to an antialcohol poster framed as an open-ended question resulted in more self-generated arguments for drinking less alcohol and more favorable message evaluations than framing the same message as a statement. Experiment 2 showed that the self-persuasion poster did not affect the choice to consume alcohol but did reduce alcohol consumption for individuals who chose to drink any alcohol, compared with a direct persuasion poster or no intervention. Together, the results demonstrated the potential of self-persuasion in persuasive media messages for interventions aimed at alcohol consumption reduction specifically and for health communication in general.

Self-Persuasion on Facebook Increases Alcohol Risk Perception.

In this experiment, we examined if participating in a Facebook group by generating antialcohol arguments (self-persuasion) is more effective than reading antialcohol posts of others (direct persuasion) in changing alcohol consumption, risk perception, and attitudes. In addition, it was examined if submitting posts moderated these effects. Participants logged into their Facebook account and joined a group that contained posts with antialcohol arguments. They either generated their own arguments with or without posting them, or read those present in the group with or without posting that they had read them. Next, participants rated movie clips in a 30-minute ad libitum drinking session in dyads, and their alcohol consumption was measured. Finally, measures of alcohol risk perception and attitudes were completed. Results show that generating antialcohol arguments-regardless of whether they are posted online-is effective in increasing alcohol risk perception but does not affect immediate alcohol consumption.

Imitation of cigarette smoking: an experimental study on smoking in a naturalistic setting.

AIMS: Examine whether smokers imitate smoking behaviour of strangers and to what extent this is moderated by the nature of social interactions. DESIGN AND PARTICIPANTS: An experiment with a three (heavy smoking, light smoking, or no smoking condition) by two (warm versus cold social interaction condition) factorial design. Daily smoking young adults were exposed to same-gender confederates and were observed in a bar laboratory. MEASUREMENTS: Smoking and social behaviour were observed and coded during a 30-min break between two tasks, consisting of rating television advertisements. FINDINGS: Participants imitated the smoking behaviour of confederates. After controlling for young people's craving, confederate's smoking explains 35% of the variance in the number of cigarettes smoked. Participants are more likely to smoke and to continue smoking in the warm social interaction condition. Lighting up the first cigarette was affected by confederate's smoking and participant's urges to smoke. Lighting up a second was affected by the heavy smoking condition and warm social interaction condition. Lighting up a third cigarette was affected only by the heavy smoking condition. CONCLUSION: Imitation largely explains why individuals light up a cigarette and continue to smoke.
