Reduction of the misinformation effect by arousal induced after learning

Misinformation introduced after events have already occurred causes errors in later retrieval. Based on literature showing that arousal induced after learning enhances delayed retrieval, we investigated whether post-learning arousal can reduce the misinformation effect. 251 participants viewed four short film clips, each followed by a retention test, which for some participants included misinformation. Afterward, participants viewed another film clip that was either arousing or neutral. One week later, the arousal group recognized significantly more veridical details and endorsed significantly fewer misinformation items than the neutral group. The findings suggest that arousal induced after learning reduced source confusion, allowing participants to better retrieve accurate details and to better reject misinformation.     

Comparative analysis of integrative self-knowledge, mindfulness, and private self-consciousness in predicting responses to stress in Iran

Previous research has established that awareness of self-experience is a stress resistance resource. The present study conducted an analysis of measures that record different aspects of self-awareness (private self-consciousness, mindfulness, and integrative self-knowledge) to explain this stress-resistance effect in a sample of Iranian university students (N = 186). These students responded to Mindfulness Attention Awareness, Private Self-Consciousness, Integrative Self-Knowledge, and Perceived Stress Scales just before the stress of a 20-day final examination period, and they then responded to Symptom Checklist and Vitality measures at four-day intervals during the final examinations. Prior to final examinations, the three self-awareness variables correlated positively with each other and negatively with perceived stress. Regression analyses of the data obtained during final examinations identified mindfulness to be a better operationalization of this stress-resistance resource than private self-consciousness. Specifically, mindfulness but not private self-consciousness was a positive predictor of vitality and a negative predictor of symptoms. Hierarchical regression analyses also demonstrated that mindfulness and integrative self-knowledge both explained resistance to physical symptoms, while integrative self-knowledge functioned as a protective factor toward one's vitality. These data confirm the positive impact that self-awareness has during stress and highlight the importance of considering both mindfulness and integrative self-knowledge in understanding stress-resistance processes.     

Elements Influencing Peer Evaluation: An Examination of Individual Characteristics,Academic Performance,and Collaborative Processes

Collaborative learning has existed for some time, and instructional methods have been developed, such as cooperative learning, team learning, and problem‐based learning. The purpose of this study is to observe students in learning teams and how their observations of their team and team members are reflected in peer evaluations. We examine pre‐ and post‐team history elements, such as basic demographics, personality factors, exam scores, and observations of team process and team goal attainment. Pre‐ and post‐team history factors correlate with peer evaluations and are discussed. In our analyses, we take into account intraclass correlations and individual and group effects. Suggestions are given for future research.     

Sport-Type Differences in Alcohol Use Among Intercollegiate Athletes

Prior research has found that (a) intercollegiate athletes are especially “at-risk” for excessive alcohol consumption (e.g., Nelson & Wechsler, 2001 Nelson, T. F. and Wechsler, H. 2001. Alcohol and college athletes. Medicine and Science in Sports and Exercise, 33: 43–47. [INFOTRIEVE][CSA][CROSSREF][Crossref], [PubMed], [Web of Science ®] , [Google Scholar]), and (b) sport-type differences exist among college athletes in terms of yearly drinking prevalence rates (National Collegiate Athletic Association, 2001 National Collegiate Athletic Association. 2001. NCAA study of substance use habits of college student-athletes, Indianapolis, IN: Author.  [Google Scholar]). No studies, however, have examined sport-type differences on more specific measures of alcohol consumption (e.g., drinks per week), or examined potential mediators of the relationship between sport type and alcohol consumption. In the present study, data were analyzed on 298 intercollegiate athletes from two different universities. Resuls indicated significant sport type differences on alcohol consumption variables, with athletes from the sports of swimming and diving reporting the highest levels of alcohol consumption. Results provided partial support for the role of positively reinforcing drinking motives in mediating the sport type–alcohol consumption relationship. Findings are discussed in light of prior research in the area of college student–athlete alcohol consumption.     

Are Past Normative Behaviors Predictive of Future Behavioral Intentions?

We acknowledge the limitations in measures of moral reasoning and pursue an alternative technique by investigating past behaviors as they relate to present behavioral intentions. Our purpose is to evaluate the merits of patterned normative behavior for predicting present and future, morally relevant outcomes. Participants (N = 177) completed a policy capturing experimental design responding to questions that orthogonally varied the situational nature of the decision context. Results indicate that past normative behaviors are significantly and directly related to ethical behavioral intentions. Moreover, they moderate the relationships between situational factors and intended outcomes as well as moral reasoning and intended outcomes.     

Selfless giving

In four studies, we show that people who anticipate more personal change over time give more to others. We measure and manipulate participants’ beliefs in the persistence of the defining psychological features of a person (e.g., his or her beliefs, values, and life goals) and measure generosity, finding support for the hypothesis in three studies using incentive-compatible charitable donation decisions and one involving hypothetical choices about sharing with loved ones.     

Gender Differences in Adolescent Self-Esteem: An Exploration of Domains

The relationship between gender and global self-esteem in adolescence, while modest, has been well established, with boys consistently scoring higher than girls. In the present study, we sought to understand gender differences in adolescent self-esteem in terms of its component parts. With a relatively large (n = 545) sample of adolescents, drawn from Grades 8, 10. and 12, we specified 8 domains of adolescent self-esteem (personal security, home/parents, peer popularity, academic competence, attractiveness, personal mastery, psychological permeability, and athletic competence) across a number of different instruments and brought them together into a common assessment superstructure. Gender differences as well as the relative contributions of the different domains to overall self-esteem scores were measured. As predicted, boys attained slightly higher global self-esteem scores than girls did, by a difference of .22 standard deviation units. Contrary to our expectation of more balanced domain effects, boys significantly outperformed girls in 6 of 8 domains, whereas the 2 remaining domains exhibited no significant gender differences. There were no main or interaction effects for grade level. In terms of relative contribution of these domains to global self-esteem for the 2 genders, global self-esteem in boys and girls is predicted in very similar strengths and in the same order of magnitude by identical domains of self-esteem: home/parents, personal security, academic competence, attractiveness, and personal mastery—yielding multiple R ²s from .88 to .91.     

Assessing Measurement and Predictive Invariance of the Toronto Alexithymia Scale–20 in U.S. Anglo and U.S. Hispanic Student Samples

We collected data from a predominately Anglo American student sample in the Southeastern United States and a predominately Hispanic student sample in the Southwestern United States. Along with an assessment of internal consistency reliability, we examined measurement invariance of the Toronto Alexithymia Scale–20 (TAS–20) using confirmatory factor analysis. We also assessed the predictive invariance of the TAS–20. Results indicate that 2 of the 3 TAS–20 subscales demonstrated satisfactory internal consistency reliability across samples. Items from the TAS–20 subscales demonstrated measurement invariance of the latent means. The relationship between 2 measures of emotional dysfunction and the TAS–20 also demonstrated slope and intercept invariance, indicating equivalent validity.     

Personality and social attitudes: Evidence for positive-approach motivation

Extensive research has linked general personality factors to social attitudes, but there has been comparatively little work on the roles played by specific approach-avoidance personality factors, especially positive-approach ones. Here we relate such factors to the two main clusters of social attitudes (Right-Wing Authoritarianism, RWA; and Social Dominance Orientation, SDO), and related cognitive constructs (Need for Cognition and Need for Closure). Results revealed: (a) positive-approach motivation is consistently related to both RWA and SDO, with little contribution from negative-avoidance motivation; and (b) negative-avoidance motivation played a part in Need for Cognition (negatively related) and Need for Closure (positively related). These data challenge previous theorizing concerning the role of fear/anxiety in social attitude formation and prejudice more generally. We conclude that, to a larger extent than previously thought, approach-related personality factors underpin the positive reinforcement of social attitudes and prejudice. Our results may help to account for the failure of programmes designed to reduce prejudice which have been based on the reduction of negative emotion and motivation.
