Self-Other Discrepancies in Waiting Time Decisions

Both anecdotal evidence and recently reported research suggest that people are risk-averse when faced with waiting time decisions. Four studies investigate whether there is a self-other discrepancy in how people make waiting time decisions themselves and how they predict others will make similar decisions. People are found to believe that others have valuations of time similar to their own. However, when faced with alternatives that involve risk in the duration of the wait, the results point to a self-other discrepancy, in that people report greater risk-aversion themselves than they think others would. Further, when faced with waiting time gains, people are themselves more risk-averse than they think others would be. Conversely, when faced with waiting time losses, people are themselves more risk-seeking than they think others would be. Overall, the results are consistent with the recently proposed risk-as-feelings hypothesis.     

Crones, Dirty Old Men, Sexy Seniors: Representations of the Sexuality of Older Persons

The representations of the sexuality of older persons in American society are neither flattering nor accurate. Often what is presented is filled with confusion, uncertainty, and contradictions. Sexuality of old people, like sexuality of adolescents, frightens most adults in between. Evidence suggests hope that in popular culture, conventional representations of sexless older people are finally undergoing a change. The popular literature aimed at elderly or midlife audiences increasingly portrays older persons as healthy, vigorous, and not unattractive. Since in the popular mind attractiveness and sexuality are believed to be closely linked, this change signals an increased willingness to credit old people who are aging well (i.e., who look and act young) with being sexually interested and probably active.     

Effects of short‐term cosmetic versus long‐term health fear appeals in anti‐smoking advertisements on the smoking behaviour of adolescents

A field study exposed 235 high school students to anti‐smoking advertisements over a five‐month period to test the effectiveness of short‐term cosmetic versus long‐term health fear appeals in preventing or reducing smoking. The study was a longitudinal experiment with two experimental groups and a control group. Smoking behaviour was measured prior to message exposure on television, in magazines and on the internet, and at the end of the study period. The primary results were that average smoking declined for subjects exposed to either type of anti‐smoking fear appeal but not for the control group and short‐term cosmetic fear appeals were more effective for males but long‐term health fear appeals were more effective for females.

学习支持对儿童在多媒体语境中学习英语词汇的影响

该研究旨在考察中文翻译与主题提示两种学习支持对儿童在多媒体语境中学习英语词汇的作用,为此设计了三种学习条件：无支持条件、中文翻译条件和中文翻译 主题提示条件。对学龄初期儿童在上述三种学习条件下学习英语词汇的过程和结果进行的考察和分析表明：儿童在无支持条件下的学习效果较差;中文翻译可以明显促进儿童对语句的理解,但无法提高儿童对目标词的掌握;中文翻译 主题提示条件下儿童对单词语义的掌握最好,他们表现出了较多的跟读行为,并更倾向于认为学习任务较为容易。     

Recognition and Reform in Nordic Fiction: Jonas Gardell and Jussi Valtonen

While contemporary Scandinavian literature continues to discuss the problems of welfare state and social justice, it increasingly turns its attention to minority issues, multiculturalism, and the impact of digitalization. Jonas Gardell's HIV/AIDS trilogy Torka aldrig tårar utan handskar (Never wipe tears without gloves) highlights the family relations in the Swedish gay community. Jussi Valtonen's He eivät tiedä mitä tekevät (They do not know what they do) deals with the dystopias of social media and the power of global software companies. Religion and theology play a significant role in the works of both Gardell and Valtonen.     

Limits to preference and the sensitivity of choice to rate and amount of food

Studies of choice holding food‐amount ratio constant while varying food‐rate ratio within sessions showed that local changes in preference depend on relative amount of food. The present study investigated whether sensitivity of choice to food‐rate ratio and sensitivity to food‐amount ratio are independent of one another when food‐rate ratios are varied across sessions and food‐amount ratios are varied within sessions. Food deliveries for rats’ presses on the left and right levers were scheduled according to three different food‐rate ratios of 1:1, 9:1, and 1:9; each food‐rate ratio lasted for 106 sessions and was arranged independently of seven food‐amount ratios (7:1, 6:2, 5:3, 4:4, 3:5, 2:6, and 1:7 food pellets) occurring within sessions in random sequence. Each amount ratio lasted for 10 food deliveries and was separated from another by a 60‐s blackout. Sensitivity to rate ratio was high (1.0) across food deliveries. Sensitivity to amount ratio was low when food rates were equal across alternatives, but was high when rate ratio and amount ratio opposed one another. When rate ratio and amount ratio went in the same direction, choice ratio reached an elevenfold limit which reduced sensitivity to approximately zero. We conclude that three factors affect sensitivity to amount: (1) the limit to preference, (2) the equal effect on preference of amounts greater than four pellets, and (3) the absence of differential effects of switches in amount in the equal‐rates (1:1) condition. Taken together, these findings indicate that rate and amount only sometimes combine independently as additive variables to determine preference when amount ratios vary frequently within sessions.     

Examination of efficacious,efficient, and socially valid error‐correction procedures to teach sight words and prepositions to children with autism spectrum disorder

Prior research shows that learners have idiosyncratic responses to error‐correction procedures during instruction. Thus, assessments that identify error‐correction strategies to include in instruction can aid practitioners in selecting individualized, efficacious, and efficient interventions. The current investigation conducted an assessment to compare 5 error‐correction procedures that have been evaluated in the extant literature and are common in instructional practice for children with autism spectrum disorder (ASD). Results showed that the assessment identified efficacious and efficient error‐correction procedures for all participants, and 1 procedure was efficient for 4 of the 5 participants. To examine the social validity of error‐correction procedures, participants selected among efficacious and efficient interventions in a concurrent‐chains assessment. We discuss the results in relation to prior research on error‐correction procedures and current instructional practices for learners with ASD.     

Stability of daily preference across multiple individuals

Preference stability provides clues about the extent to which a clinician might be able to deliver a particular stimulus contingent on behavior as a reinforcer. Previous research has been somewhat mixed in terms of evidence for preference stability. Results of the current study are consistent with studies that have reported correlations between preference assessments, suggesting that preferences are relatively stable across time.     

Assessing the Impact of a Media‐based Intervention to Prevent Intergroup Violence and Promote Positive Intergroup Relations in Burundi

The present study (N = 1074) examined the impact of a theory‐driven media intervention aimed at violence prevention and intergroup reconciliation in Burundi. We used a novel methodology utilizing audio‐based surveys to assess attitudes related to intergroup conflict and reconciliation among community members. We conducted a propensity score analysis to estimate the causal effects of the intervention by examining differences between listeners and non‐listeners of the radio dramas. The results indicated a positive effect of the intervention on several social psychological outcomes (tolerance, in‐group superiority, social distance, intergroup trust, responsibility attributions, trauma disclosure and competitive victimhood). However, listeners and non‐listeners did not differ in obedience toward leaders or historical perspective taking; and the results for active bystandership, one of the main foci of the intervention, were mixed. Furthermore, the results show that the impact of the intervention sometimes depends on listeners' personal experiences of victimization. Copyright © 2015 John Wiley & Sons, Ltd.
