On the Diagnosticity of Multiple-Witness Identifications

It is not uncommon for there to be multiple eyewitnesses to a crime, each of whom is later shown a lineup. How is the probative value, or diagnosticity, of such multiple-witness identifications to be evaluated? Previous treatments have focused on the diagnosticity of a single eyewitness’s response to a lineup (Wells and Lindsay, Psychol. Bull. 3 (1980) 776); however, the results of eyewitness identification experiments indicate that the responses of multiple independent witnesses may often be inconsistent. The present paper calculates response diagnosticity for multiple witnesses and shows how diagnostic probabilities change across various combinations of consistent and inconsistent witness responses. Multiple-witness diagnosticity is examined across variation in the conditions of observation, lineup composition, and lineup presentation. In general, the diagnostic probabilities of guilt were shown to increase with the addition of suspect identifications and decrease with the addition of nonidentifications. Foil identification results were more complicated-diagnostic of innocence in many cases, but nondiagnostic or diagnostic of innocence in biased lineups. These analyses illustrate the importance of securing clear records of all witness responses, rather than myopically focusing on the witness who identified the suspect while ignoring those witnesses who did not.     

The Effects of Pre-admonition Suggestions on Eyewitnesses’ Choosing Rates and Retrospective Identification Judgments

Pre-admonition suggestion is an identification-relevant comment made to an eyewitness by a lineup administrator before the lineup admonition. Quinlivan et al. (2012) found that their suggestion inflated mistaken identification rates and retrospective identification. However, the suggestion used was a compound statement, making it unclear which component influenced choosing rates. The current experiment was conducted to parse out the effects. Participants (N = 211) viewed a crime video and received either one component of the compound suggestion (a suggestion to pick or that the witness had paid substantial attention), both components, or no suggestion. All participants received an admonition, made an identification choice, and answered questions about their witnessing experience. The results demonstrated that the pick suggestion increased mistaken identifications from a perpetrator-absent lineup whereas the effects of the attention suggestion were restricted to the retrospective judgments. These results show support for the role of secondary (non-memorial) processes in eyewitness identification.     

You All Made Dank Memes: Using Internet Memes to Promote Critical Thinking

In the time following the 2016 presidential election, much has been written about the spread of false information on social media websites. Given the potential influence false information has had on American politics, it is more important than ever for people to critically evaluate the content they view and share on social media. This article describes an activity that encourages students to develop evidence based arguments and think critically about content shared on social media. In the activity, students are asked to generate an internet meme related to U.S. politics and write a short essay defending the position they have taken in the meme. This article explains how the activity can promote critical thinking and includes suggestions for future implementation.     

Following the Party in Time of War? The Implications of Elite Consensus

Prominent perspectives in the study of conflict point to two factors that exert substantial influence on public opinion about foreign intervention: (1) news about casualties and (2) signals from partisan elites. Past work is limited, however, in what it can say about how these two factors interact. We present an experiment designed to understand the surprisingly common scenario where elites send competing messages about whether the public should support war or oppose it—and these messages do not coincide with party divisions. We find that partisans are generally insensitive to news about casualties, but they become noticeably more sensitive when they perceive within-party disputes over support for the war. Independents, however, respond to news of casualties irrespective of what messages elites send. These findings shed light on when and how the public responds to competing and unclear cues and speak to the role of public opinion in determining conflict outcomes and democratic foreign policy-making more broadly.     

Intergenerational Continuity in Depression: The Importance of Time-Varying Effects,Maternal Co-morbid Health Risk Behaviors and Child’s Gender

Intergenerational continuity in depressive symptoms is well established between mother and child, but there are still important facets of this relationship that are underexplored. We examine intergenerational continuity in depressive symptoms between mother–child dyads as a flexible function of child age and account for the potential moderating role of maternal co-morbid health risk behaviors. Using prospective, self-report data collected yearly from 413 mother–child dyads (210 mother–son dyads and 203 mother–daughter dyads) between child ages 12–17, the results indicate that the effect of maternal depressive symptoms on daughters’ depressive symptoms steadily increases throughout adolescence whereas the effect of maternal depressive symptoms on sons’ depressive symptoms is relatively small, stable, and non-significant during mid-adolescence before increasing in effect in later adolescence. A positive interactive effect between maternal depressive symptoms and intimate partner violence is observed for sons and maternal depressive symptoms and substance use for daughters. A negative interactive effect of maternal depressive symptoms and substance use is observed among sons. Overall, this study identifies particular subgroups for whom intervention programming is most beneficial and suggests targeting health risk behaviors of mothers to lessen the impact of maternal depressive symptoms on offspring.     

Maternal Depressive Symptoms and Adolescent Health Risk Problems: The Role of School Engagement

Maternal depressive symptoms disrupt positive youth development, though the pervasiveness of this disruption is understudied. Additionally, it remains unknown whether prosocial factors such as adolescent school engagement may buffer against this risk factor. Using multigenerational, longitudinal data spanning ten years from an ethnically diverse sample of mother-child dyads (66% Black, 17% Hispanic, and 17% White), this study examines the effect of maternal depressive symptoms in late childhood (ages 8–13) on the development and progression of offspring depressive symptoms, substance use, and delinquent behavior during adolescence (ages 14–17). Further, the study examines whether school engagement moderates the ill effects of maternal depressive symptoms. Mother-son (n?=?212) and mother-daughter (n?=?215) dyads are compared to assess for similarities and differences between male and female offspring. The results indicate that offspring of mothers with greater maternal depressive symptoms are more likely to display higher levels of depressive symptoms, substance use, and delinquency throughout adolescence, although important nuances emerge across outcome and child sex. Additionally, while school engagement itself is associated with reduced depressive symptoms, substance use and delinquency among adolescents, it is not profound enough to offset the risk posed by maternal depressive symptoms. The findings of this study reinforce the pervasive, negative, intergenerational impact of maternal depressive symptoms and has implications for prevention and intervention efforts for adolescent health risk problems.

     

The validity of criminal justice contacts reported by inmates: A comparison of self-reported data with official prison records

Purpose

Existing research on criminal justice contact data has not adequately examined the quality of self-reported timing data, has produced discrepant findings on validity as it relates to demographics, and is limited in its assessment of data quality using a life event calendar method. The study described in this article assessed the validity of self-reported contacts with the criminal justice system gathered using a life event calendar with a sample of incarcerated men.

Methods

Self-reports of criminal justice contacts (i.e., arrests, jail terms, prison terms) were obtained from over 700 incarcerated men using a structured life-event calendar method. Similarly, data were collected from the inmate's official records for the same events. These reports served as an external criterion for the self-reports.

Results

Results indicated a significant degree of reporting errors for arrests using the life event calendar approach with better reporting for jail and prison terms. Additionally, individuals with the highest number of previous arrests had the greatest recall difficulties.

Conclusions

Recall of arrest presents a difficult recall task. The life event calendar method should either be modified to improve recall of specific events for criminological samples or used instead to capture information on more general and extended events.
