Endowment effect despite the odds

Can ownership status influence probability judgements under condition of uncertainty? In three experiments, we presented our participants with a recording of a real horse race. We endowed half of our sample with a wager on a single horse to win the race, and the other half with money to spend to acquire the same wager. Across three large studies (N = 750), we found the endowment effect – owners demanded significantly more for the wager than buyers were willing to pay to acquire it. However, we also found that probability estimates of each horse winning the race did not differ between owners and non-owners of the betting slip. Our results demonstrate that distorted perception of probability is unlikely to be a mechanism explaining the endowment effect.     

More than a Media Moment: The Influence of Televised Storylines on Viewers’ Attitudes toward Transgender People and Policies

Numerous studies have demonstrated the power of entertainment narratives to influence attitudes and behaviors; fewer have examined the effects of TV portrayals on attitudes toward marginalized groups. The present study is among the first to explore how entertainment narratives depicting transgender individuals influence viewers’ attitudes toward transgender people and related policies. The study examines the impact of exposure to a TV storyline on Royal Pains (USA Network) and cumulative effects of viewing other TV series featuring transgender individuals. An online survey of 488 U.S. viewers of Royal Pains was conducted (391 had seen the relevant episode). ANCOVAs revealed exposure to both the Royal Pains’ storyline and other storylines portraying transgender individuals were associated with more supportive attitudes toward transgender people and policies. Mediation models revealed that for viewers of the Royal Pains’ storyline, the relationships between political ideology and attitudes toward transgender people and policies were mediated by identification with the main characters and the emotion of hope. Disgust mediated viewers’ attitudes toward transgender people, but not policies. Post hoc analyses revealed that exposure to transgender narratives reduced the influence of viewers’ political ideology on their attitudes. The attitudes of more conservative viewers became increasingly positive as they saw more media portrayals of transgender individuals. These findings highlight the potential for entertainment narratives to influence attitudes toward marginalized groups, and they demonstrate the importance of emotion in the context of divisive topics. Social, political, and public health implications are discussed.

Does overgeneral autobiographical memory result from poor memory for task instructions?

Considerable previous research has shown that retrieval of overgeneral autobiographical memories (OGM) is elevated among individuals suffering from various emotional disorders and those with a history of trauma. Although previous theories suggest that OGM serves the function of regulating acute negative affect, it is also possible that OGM results from difficulties in keeping the instruction set for the Autobiographical Memory Test (AMT) in working memory, or what has been coined “secondary goal neglect” (Dalgleish, 2004). The present study tested whether OGM is associated with poor memory for the task's instruction set, and whether an instruction set reminder would improve memory specificity over repeated trials. Multilevel modelling data-analytic techniques demonstrated a significant relationship between poor recall of instruction set and probability of retrieving OGMs. Providing an instruction set reminder for the AMT relative to a control task's instruction set improved memory specificity immediately afterward.     

The Appropriate Use and Misuse of Social Media in MFT Training Programs: Problems and Prevention

Directors of accredited marriage and family therapy programs were surveyed to determine what problems they had experienced resulting from student, faculty, and client misuse of social media. Approximately 40 % of the programs had encountered a problem resulting from student misuse of social media. The directors were also asked what efforts were made by their program and university to promote the appropriate use of social media, with programs assuming primary responsibility for addressing this issue. The study also assessed attitudes among directors regarding how to handle potential issues that may arise in training programs regarding the use of social media. Implications for training programs are provided.     

Motivated expectations of positive feedback in social interactions

People self-enhance in a variety of ways. For example, they generally expect to perform better than others, to be in control of events, and to have a brighter future. Might they also self-enhance by expecting to receive positive feedback in social interactions? Across five studies, we found that they did. People's desire for feedback correlated with how positive they expected it to be (Study 1), and their feedback expectations were more positive for themselves than for others (Study 2). People's positive feedback expectations also covaried with trait tendencies to self-enhance (i.e., self-esteem and narcissism; Study 3) and with a direct situational manipulation of self-enhancement motivation (Study 4). Finally, people expected to receive positive feedback but did not consistently expect to receive self-verifying feedback (Study 5). These findings are consistent with social expectations being driven in part by the self-enhancement motive.
