Simultaneous Lineups,Sequential Lineups,and Showups: Eyewitness Identification Decisions of Adults and Children

Two experiments were conducted comparing the identification accuracy of children aged 3–15 years (N = 307) and undergraduates (N = 384) using target-present and target-absent simultaneous and sequential lineups and showups. Correct identification rates tended not to vary across either age of subject or identification procedure. However, children show a significant tendency to guess as indicated by their lower rate of correct rejection when the target is absent. The tendency for children to make false positive choices was particularly evident with showups.     

The Forgotten Summer: Does the Offer of College Counseling After High School Mitigate Summer Melt Among College‐Intending,Low‐Income High School Graduates?

Despite decades of policy intervention to increase college entry and success among low‐income students, considerable gaps by socioeconomic status remain. To date, policymakers have overlooked the summer after high school as an important time period in students’ transition to college, yet recent research documents high rates of summer attrition from the college pipeline among college‐intending high school graduates, a phenomenon we refer to as “summer melt.” We report on two randomized trials investigating efforts to mitigate summer melt. Offering college‐intending graduates two to three hours of summer support increased enrollment by 3 percentage points overall, and by 8 to 12 percentage points among low‐income students, at a cost of $100 to $200 per student. Further, summer support has lasting impacts on persistence several semesters into college.     

Examining the Light and Dark Sides of Emerging Adults�� Identity: A Study of Identity Status Differences in Positive and Negative Psychosocial Functioning

Identity is a critical developmental task during the transition to adulthood in Western societies. The purpose of the present study was to evaluate an empirically based, cluster-analytic identity status model, to examine whether all four of Marcia's identity statuses (diffusion, foreclosure, moratorium, and achievement) would emerge empirically, and to identify different patterns of identity formation among American college-attending emerging adults. An ethnically diverse sample of 9,034 emerging-adult students (73% female; mean age 19.73?years) from 30 U.S. universities completed measures of identity exploration (ruminative, in breadth, and in depth) and commitment (commitment making and identification with commitment), identity synthesis and confusion, positive and negative psychosocial functioning, and health-compromising behaviors. The identity status cluster solution that emerged provided an adequate fit to the data and included all four of Marcia's original identity statuses, along with Carefree Diffusion and Undifferentiated statuses. Results provided evidence for concurrent validity, construct validity, and practical applicability of these statuses. Implications for identity research are discussed.
