How elevated blood alcohol concentration level and identification format affect eyewitness memory: A field study

Research shows that alcohol has a small and inconsistent effect on eyewitness recall and no effect on witnesses' lineup decisions. Much of this literature has tested participants with low‐to‐moderate blood alcohol concentration (BAC) levels, and no study has directly examined how identification procedure impacts intoxicated witnesses' decisions. In the present study, bar patrons' (N = 132) BAC levels were recorded before participating in a task. Midway through the task, they were interrupted by an intruder. Participants then recalled the incident via a staged interview and attempted to identify the intruder from a target‐present or target‐absent showup or lineup. Although elevated BAC levels (high as 0.24%) reduced the quantity and quality of information provided, BAC had no effect on witnesses' identification decisions regardless of format. Results highlight the importance of testing witness memory across a broad BAC spectrum and provide evidence that alcohol does not affect witnesses' identification ability.     

Social Anxiety Among Adolescents: Linkages with Peer Relations and Friendships

This study examined the utility of modifying the Social Anxiety Scale for Children—Revised (SASC-R) for use with adolescents, and examined associations between adolescents' social anxiety (SA) and their peer relations, friendships, and social functioning. Boys (n = 101) and girls (n = 149) in the 10th through 12th grades completed the Social Anxiety Scale for Adolescents (SAS-A) and measures of social support, perceived competence, and number and quality of their best friendships. Factor analysis of the SAS-A confirmed a three-factor structure: Fear of Negative Evaluation, Social Avoidance and Distress in General, and Social Avoidance Specific to New Situations or Unfamiliar Peers. Girls reported more SA than boys, and SA was more strongly linked to girls' social functioning than boys'. Specifically, adolescents with higher levels of SA reported poorer social functioning (less support from classmates, less social acceptance), and girls with higher levels of SA reported fewer friendships, and less intimacy, companionship, and support in their close friendships. These findings extend work on the SASC-R to adolescents, and suggest the importance of SA for understanding the social functioning and close friendships of adolescents, especially girls.     

Examining the positive effects of rapport building: When and why does rapport building benefit adult eyewitness memory?

Most investigative interviewing protocols recommend building rapport with cooperative adult witnesses to increase the accuracy of their reports. Although a few recent studies support the benefits of rapport building on adult witness recall, no study has examined whether the timing of rapport in relation to post-event misinformation affects recall accuracy, and whether these effects are related to witness anxiety levels throughout the interview. The present study provided two hundred and thirty-three undergraduates with a videotaped mock crime followed by building high or low rapport either before or after they received post-event misinformation. All witnesses were then interviewed about the mock crime. Results indicated that high rapport before misinformation increased the amount of accurate information reported in a subsequent witness interview compared to low rapport. However, these recall benefits were not due to a reduction in anxiety. Theoretical implications and practical recommendations for police interviewing practices are discussed.     

Rapport‐Building During Witness and Suspect Interviews: A Survey of Law Enforcement

Building rapport with adult witnesses and suspects is recommended by major investigative interviewing protocols (e.g., Cognitive Interview and the Army Field Manual in the USA and PEACE in the UK). Although recent research suggests that building rapport can sometimes benefit police investigations by increasing the accuracy of adult eyewitness reports and potentially enhance the diagnosticity of evidence obtained from suspects, little data exist regarding how law enforcement interviewers actually define and build rapport in real‐world investigations. To fill this void, the present study distributed a questionnaire containing open and closed‐ended questions to 123 law enforcement interviewers in police training courses to determine how they conceptualize and build rapport with adult interviewees. Results indicate that a majority of law enforcement interviewers define rapport as a positive relationship involving trust and communication, with a strong minority defining rapport as a ‘positive or negative’ relationship. Further, law enforcement interviewers reported building rapport with adult witnesses and suspects in a similar manner, often by using verbal techniques (e.g., discussing common interests via small talk) and non‐verbal techniques (e.g., displaying understanding via empathy and sympathy). Theoretical and applied implications of these results are discussed. Copyright © 2015 John Wiley & Sons, Ltd.     

The influence of cognitive emotion regulation strategies and depression severity on deliberate self-harm

Elaborating on previous studies on emotion regulation and deliberate self-harm (DSH), in the present study we distinguish between strategies of cognitive content (e.g., suicidal cognitions of perceived burdensomeness, helplessness, poor distress tolerance) and cognitive process (e.g., nonacceptance of emotional responses, lack of awareness of emotional responses). Young women who harmed themselves (n = 85) were compared with young women without a history of DSH (n = 93) across a broad range of strategies. Significant group differences were found for all measures, even when depression severity was controlled for. In addition, logistic regression analyses showed that both cognitive content strategies and cognitive process strategies made significant independent contributions to the prediction of group membership. Controlling for depression severity, suicidal cognitions, and nonacceptance of emotional responses independently predicted DSH. The strong association between suicidal cognitions and DSH seems to indicate the important role of these cognitions in recurrent and chronic DSH. The strong association between nonacceptance of emotional responses and DSH underscores the notion that DSH can be a way to avoid emotional problems. These findings are discussed in relation to recent cognitive-behavioral interventions and specific therapeutic techniques to further insight into how these interventions might work.     

Anticipatory and control processes in the interaction with secondary tasks while driving

The paper describes an experiment where anticipatory processes in the interaction with secondary tasks while driving could be explicitly identified and contrasted to control processes during the engagement in the secondary task. A special experimental set-up in a driving simulator environment was created that allows drivers to deliberately decide whether they want to be distracted or not depending on the driving situation and the expected development of that situation. As indicators for a situation-adaptive interaction with secondary tasks parameters from driving behaviour, secondary task performance and visual behaviour were analyzed. A study with 24 test drivers revealed that drivers are, in general, able to interact with a secondary task in a situation-aware manner. For example, drivers rejected more secondary tasks in already highly demanding situations or tried to delay the beginning of the task. During secondary task performance drivers observed the situational development with short control glances back to the road and adapted their speed. The analysis of driving errors revealed that rejecting a task in an already highly demanding driving situation is an effective strategy to maintain an adequate level of driving safety. However, some critical factors were identified that might hinder the driver from executing such strategies. Several recommendations for supporting the driver on this issue are given.     

A comfortable witness is a good witness: rapport‐building and susceptibility to misinformation in an investigative mock‐crime interview

Major investigative interviewing protocols such as the Cognitive Interview recommend that investigators build rapport with cooperative adult witnesses at the beginning of a police interview. Although research substantiates the benefits of rapport‐building on the accuracy of child witness reports, few studies have examined whether similar benefits apply to adult witnesses. The present study investigated whether verbal rapport‐building techniques increase adult witness report accuracy and decrease their susceptibility to post‐event misinformation. One‐hundred eleven college adults viewed a videotaped mock‐crime, received post‐event misinformation (or correct information) about the crime, and were subsequently interviewed by a research assistant who built rapport (or did not build rapport) before recalling the mock‐crime. Results indicated that rapport‐building increased the quality of witness recall by decreasing the percentage of inaccurate and misinformation reported, particularly in response to open‐ended questions. We discuss implications and recommendations for law enforcement. Copyright © 2011 John Wiley & Sons, Ltd.     

Inexpensive video cameras used by parents to record social communication in epidemiological investigations in early childhood-A feasibility study

We tested the feasibility of parents recording social interactions with their infants using inexpensive camcorders, as a potential method of effective, convenient, and economical large scale data gathering on social communication. Participants were asked to record two short video clips during either play or a mealtime, and return the data. Sixty-five video clips (32 pairs) were returned by 33 families, comprising 8.5% of families contacted, 44.6% of respondents and 51.6% of those sent a camcorder, and the general visual and sound quality of the data was assessed.Audio and video quality were adequate for analysis in 85% of clips and several social behaviours, including social engagement and contingent responsiveness, could be assessed in 97% of clips. We examined two quantifiable social behaviours quantitatively in both adults and infants: gaze direction and duration, and vocalization occurrence and duration. It proved difficult for most observers to obtain a simultaneous clear view of the parents and infant's face.Video clips obtained by parents are informative and usable for analysis. Further work is required to establish the acceptability of this technique in longitudinal studies of child development and to maximize the return of usable data.     

Does alcohol loosen the tongue? Intoxicated individuals' willingness to report transgressions or criminal behavior carried out by themselves or others

Police commonly interview intoxicated suspects. This is concerning when suspects are innocent because intoxication often leads to a higher risk for impulsive decision making and reduces inhibition. However, the manner in which intoxication affects people's reporting of unethical or criminal actions carried out by themselves or others is unknown and was thus addressed in the current study. Participants (N = 116) were randomly assigned to one of six conditions based on a 2 (transgression: self, other) × 3 (alcohol condition: low‐to‐moderate intoxication, placebo, sober‐control) between‐participants design. After drinking their assigned beverages, participants were asked to disclose a transgression. No main effect of alcohol emerged. However, the odds that participants would report a transgression were significantly higher if they were asked to report a personal, rather than someone else's, transgression. Overall, low‐to‐moderate intoxication did not increase the likelihood of sensitive information disclosure in this initial study, but additional research is needed.     

The melody of surprise: maternal surprise vocalizations during play with her infant

Two groups of mothers and their infants (24 infants, mean age=3.5 months and 24 infants, mean age=5.5 months) were video‐ and audio‐taped in their homes while playing with a Jack‐in‐the‐box. The mean fundamental frequency of spontaneous surprise exclamations of mothers when opening the toy were analysed, and infant and maternal facial expressions of surprise were coded in three regions of the face. A t‐test established that significantly more of the older children in comparison with younger children showed surprise (t=?2.96, df=46, p<0.005, 2‐tailed). Twenty‐nine per cent of the younger infants, in comparison with 67% of the older children showed facial expressions of surprise. A t‐test of maternal pitch height (Hz) indicated that mothers exclaimed in surprise with a higher pitch when the child did not show a surprise facial expression (mean=415.61 Hz) in comparison with the child showing surprise (mean=358.97 Hz; t=2.9, df=46, p=0.006, 2‐tailed). A multiple regression established that infant's expression was a stronger predictor of maternal vocal pitch than was the age of the infant. These results are discussed in terms of maternal use of emotional expressions as ‘social signals’. Copyright © 2002 John Wiley & Sons, Ltd.
