Does methodology matter in eyewitness identification research? The effect of live versus video exposure on eyewitness identification accuracy

The present study examined the effect of mode of target exposure (live versus video) on eyewitness identification accuracy. Adult participants (N=104) were exposed to a staged crime that they witnessed either live or on videotape. Participants were then asked to rate their stress and arousal levels prior to being presented with either a target-present or -absent simultaneous lineup. Across target-present and -absent lineups, mode of target exposure did not have a significant effect on identification accuracy. However, mode of target exposure was found to have a significant effect on stress and arousal levels. Participants who witnessed the crime live had higher levels of stress and arousal than those who were exposed to the videotaped crime. A higher level of arousal was significantly related to poorer identification accuracy for those in the video condition. For participants in the live condition however, stress and arousal had no effect on eyewitness identification accuracy. Implications of these findings in regards to the generalizability of laboratory-based research on eyewitness testimony to real-life crime are discussed.

The welfare cost of terrorism

Data from 117 countries over the period 2006 to 2011 are used to estimate a macroeconomic cross-country system of equations that examines the association between terrorism, self-reported life satisfaction, and national income. Results indicate that terrorism is negatively associated with life satisfaction, whereas no such association is found between terrorism and real GDP per worker. Stark contrasts are found, however, between OECD and non-OECD members. In all, our results suggest that the social costs of terrorism are potentially much higher than the economic costs, and measuring only the conventional economic costs of terrorism significantly underestimates the true costs.     

The Role of Friends in Early Adolescents’ Academic Self-competence and Intrinsic Value for Math and English

In a sample of 207 eighth grade students, we examined similarities between students and their friends in achievement motivation and whether friendship support moderated these associations. Academic self-competence and intrinsic value for math and English were assessed using both perceptions of friends and actual friend reports collected through friend nominations. For both sources of information, there was a stronger positive association between students’ and friends’ academic self-competence when friendships were rated as more supportive. Analyses predicting intrinsic value for math and English provided weaker evidence of an interaction. Comparisons of the students’ perceptions and their friends’ actual reports suggested that students overestimated the degree to which their friends had attitudes similar to their own. Students also perceived that their friends valued academics significantly less than the friends actually reported. Results suggest that both friend and friendship characteristics are important for understanding student achievement motivation.

Adolescent Sexual Activity: Links Between Relational Context and Depressive Symptoms

Little is known about the impact of the relational context of adolescent sexual activity on depressive symptoms. The present study examined trajectories of depressive symptoms among 6,602 adolescents (44% male, 60% White) taken from a nationally representative study (Add Health). Sexually active youth in romantic and casual relationships were first compared to virgins and then to each other by relational context. Longitudinal, multilevel models examined differences in the course of depressive symptoms based on sexual activity separately by gender and age group (ages 12–14 and 15–18). Results indicated that when compared to virgins, any differences in depressive symptoms by relational context of sex were present prior to youth’s sexual debut. The few significant differences found between youth who had sex in romantic relationships verses those who had casual sex were present before sexual initiation and not maintained over time, suggesting that casual sex in adolescence is not associated with long-term risks for depressive symptoms.
