Sporting Achievement: What Is the Contribution of Digit Ratio?

Second-to-fourth digit ratio, a marker for prenatal testosterone levels, has been shown to be associated with sporting achievement in men. It is unclear, however, whether digit ratio makes a contribution over and above salient personality variables. The present study, which included female participants, measured four personality traits and one cognitive ability (mental rotation) that have been linked to both sports achievement and sex. The significant relationship between digit ratio and sporting achievement was nearly identical in women and men. A multiple regression showed that when significant correlates of sporting ability (weight, height, years playing, hours per week training, social potency, and mental rotation) were entered first, the contribution of digit ratio remained highly significant. We suggest that physiological as well as psychological factors may be an important avenue for future study.     

The Individual or the Group: A Multilevel Analysis of Cyberbullying in School Classes

In this study, we focus on the relevance of social influence to explain cyberbullying experiences among German high school students. Social influence is discussed in the context of computer‐mediated communication. To obtain individual and sociostructural data, we conducted a survey study among German high school students (N = 4,282). Using multilevel modeling, we found that the attributes of the school class only contributed to the risk of being involved in cyberbullying to a small extent. Still, procyberbullying norms in class did enhance the risk of perpetration and victimization for students, even more so than their individual beliefs. Previous experiences with bullying and intensive, unrestricted use of the Internet were the strongest individual predictors of cyberbullying involvement.     

AUTOMATIC RELATIONSHIP–HARM ASSOCIATIONS AND INTERPERSONAL TRAUMA INVOLVING CLOSE OTHERS

Women exposed to violence early in life are at risk of revictimization. The interpersonal schema hypothesis of revictimization proposes that revictimized women will be more likely to hold negative expectations about intimate relationships, including expectations that relationships involve harm, relative to singly or nonvictimized women. To test the interpersonal schema hypothesis, we used the implicit lexical decision task to examine automatic associations between relationship and harm concepts among college women who reported histories of no, single, or multiple types of interpersonal trauma involving close others (e.g., family member, partner). Women exposed to multiple types of interpersonal trauma involving close others showed stronger relationship–harm associations than singly or nonexposed women. Relationship–harm associations predicted the number of interpersonal trauma types (e.g., sexual, physical trauma) involving close others reported by participants, but were unrelated to posttraumatic stress disorder (PTSD) symptoms. Findings suggest that relational schemata held by women exposed to multiple types of interpersonal trauma involving close others include concepts of harm, which may have implications for how multiply victimized women behave in and think about intimate relationships.     

Conceptual priming with pictures and environmental sounds

A series of experiments was conducted to examine conceptual priming within and across modalities with pictures and environmental sounds. In Experiment 1, we developed a new multimodal stimulus set consisting of two picture and sound exemplars that represented 80 object items. In Experiments 2, we investigated whether categorization of the stimulus items would be facilitated by picture and environmental sound primes that were derived from different exemplars of the target items; and in Experiments 3 and 4, we tested the additional influence on priming when trials were consolidated within a target modality and the inter stimulus interval was lengthened. The results demonstrated that target categorization was facilitated by the advanced presentation of conceptually related exemplars, but there were differences in effectiveness when pictures and sounds appeared as primes.     

Confidence–accuracy resolution in the misinformation paradigm is influenced by the availability of source cues

After witnessing an event, people often report having seen details that were merely suggested to them. Evidence is mixed regarding how well participants can use confidence judgments to discriminate between their correct and misled memory reports. We tested the prediction that the confidence–accuracy relationship for misled details depends upon the availability of source cues at retrieval. In Experiment 1, participants (N = 77) viewed a videotaped staged crime before reading a misleading narrative. After seven minutes or one week, the participants completed a cued recall test for the details of the original event. Prior to completing the test, all participants were warned that the narrative contained misleading details to encourage source monitoring. The results showed that the strength of the confidence–accuracy relationship declined significantly over the delay. We interpret our results in the source monitoring framework. After an extended delay, fewer diagnostic source details were available to participants, increasing reliance on retrieval fluency as a basis for memory and metamemory decisions. We tested this interpretation in a second experiment, in which participants (N = 42) completed a source monitoring test instead of a cued recall test. We observed a large effect of retention interval on source monitoring, and no significant effect on item memory. This research emphasizes the importance of securing eyewitness statements as soon as possible after an event, when witnesses are most able to discriminate between information that was personally seen and information obtained from secondary sources.
