Choosing Your Words and Pictures Wisely: When Do Individuation Instructions Reduce the Cross‐Race Effect?

Recognition accuracy for faces of an individual's own race typically exceeds recognition accuracy for other‐race faces. The categorization–individuation model (Hugenberg, Young, Bernstein, & Sacco, 2010) attributes this cross‐race effect to motivation to encode distinctive features of own‐race faces but category defining features for other‐race faces. Two experiments using different stimuli tested hypotheses generated from this model with both Black and White participants. For White participants, instructions to individuate reduced the cross‐race effect in both studies but did not eliminate it in Study 1. Black participants did not exhibit the cross‐race effect in either study, but individuation instructions improved both their same‐race and other‐race sensitivity. The present quality of interracial contact moderated the relationship between instructions and other‐race sensitivity for both Black and White participants in Study 1 but not in Study 2. Overall, results provide mixed support for this social categorization model. Copyright © 2015 John Wiley & Sons, Ltd.     

Naturalistic evaluation of suicidal ideation: variability and relation to attempt status

Suicidal ideation has been thought to have a relatively stable course across weeks and months. However, daily changes in levels of ideation have not been adequately examined despite the importance of potential variability clinically and conceptually. For example, it has been suggested that variability in suicidal ideation may become less closely tied to variability in other mood symptoms (e.g., depression, hopelessness) among individuals with multiple suicide attempts. The present report had two related goals: (1) to prospectively evaluate suicidal ideation and related mood symptoms, and (2) to determine whether suicide attempt status predicted a decreased association between ideation and other mood symptoms. Non-clinical participants (N=108) with varying levels of suicidal ideation and number of previous suicide attempts completed the beck hopelessness scale (BHS), beck depression inventory (BDI), and suicide probability scale (SPS) every day for 4 weeks. Findings suggested considerable variability in suicidal ideation, especially for multiple attempters. Multiple attempt status predicted a decreased association between suicidal ideation and depression, although the results were only marginally significant. These findings have implications for conceptual models of suicide risk as well as assessment and treatment of suicidal individuals.     

A novel view of between-categories contrast and within-category assimilation

This research manipulated the portion of a category distribution that is misclassified by the optimal classifier and investigated the impact on assessments of category attributes. Three separate studies manipulated the direction of overlap, the extent of overlap, and the relative base rate of the comparison category. All 3 studies produced large between-categories contrast and within-category assimilation. As expected, these effects were enhanced in conditions in which the optimal classifier misclassified a larger portion of the target category. Study 4 demonstrated that intercategory overlap in the absence of overt classification does not produce contrast and assimilation. Ironically, optimizing categorization accuracy can produce highly inaccurate beliefs about category attributes.     

Domain specific effects of central traits in impression formation

In a procedure similar to that used in Asch's classic studies in 1946, 125 college students (54 men and 71 women, Mage=20.9 yr., SD=4.8) rated their impression of a hypothetical man or woman who was described by seven stimulus traits. This list included one of four central traits which appeared in the middle of the list: warm, cold, serious, or foolish. The dependent measures were factor scores derived from participants' ratings of 20 traits on social desirability and intellectual desirability. As hypothesized, warm and cold, prototypes of social desirability and undesirability, were associated with judgments of social but not intellectual desirability, and serious and foolish, prototypes of intellectual desirability and undesirability, were associated with judgments of intellectual but not social desirability. In addition, there was evidence of a subtle sex bias: ratings of "foolish" women were higher on social desirability than ratings of "foolish" men.     

Comparing the constructs of antisocial personality disorder and psychopathy in a sample of incarcerated women

Our study examines the relationship between Antisocial Personality Disorder (APD) and psychopathy among a sample of 137 female offenders. Drawing from a historical review of the evolution of these two concepts, we explore their differential relationship to patterns of criminal behavior, psychological adjustment, co-morbidity with other personality disorders, victimization, and institutional adjustment. Findings suggest that the two disorders share a common foundation of social norm violations and deception; however, APD is associated with impulsive, aggressive, and irresponsible behavior, higher rates of childhood abuse, and greater co-morbidity with Cluster A PDs, while psychopathy is better characterized by higher rates of property crimes, previous incarceration, and the manifestation of remorselessness. Results contribute to a further understanding of the etiology and phenomenology of these two disorders and suggest different types of treatment and intervention.     

Mourning and the symbolic process

Abstract: This paper describes the analysis of a patient whose difficulty symbolizing absence had prevented her from being able to mourn the loss of her father in her adolescence. Through a series of symbolic enactments and synchronistic events, she was eventually able to carry out a mourning ritual that enabled her to lay her father to rest. Some implications for symbolization are discussed, developing Segal's view of symbol formation as reparation: symbols are embedded in a context of communication and can only develop in the context of a relationship; they represent relationships as well as objects; and they are emergent in the sense that they exist within a complex web of interactive, multiple meaning and cannot be reduced back to any one object that they represent.     

Elements Influencing Peer Evaluation: An Examination of Individual Characteristics,Academic Performance,and Collaborative Processes

Collaborative learning has existed for some time, and instructional methods have been developed, such as cooperative learning, team learning, and problem‐based learning. The purpose of this study is to observe students in learning teams and how their observations of their team and team members are reflected in peer evaluations. We examine pre‐ and post‐team history elements, such as basic demographics, personality factors, exam scores, and observations of team process and team goal attainment. Pre‐ and post‐team history factors correlate with peer evaluations and are discussed. In our analyses, we take into account intraclass correlations and individual and group effects. Suggestions are given for future research.     

Learning fine-grained and category information in navigable real-world space

Spatial judgments are affected by both fine-grained and categorical knowledge. We investigated whether, and how, the two forms of knowledge are learned in real-world, navigable space, as well as the time course of learning each type of knowledge. Participants were Northwestern University undergraduates who estimated the locations of buildings and other landmarks on campus. The Northwestern campus is roughly divided into three regions whose borders are not easy to discern, either from a map or by navigation. Nevertheless, students often refer to these regions linguistically and use them when making housing decisions, choosing classes, and so forth. We found that knowledge of both the fine-grained configuration of locations and the regional distinctions increased with time. However, regional influences on judgments occurred later in students’ time on campus. Consequently, computed distances across the nonexistent border between north and south campus locations became more biased with time. The results have implications for understanding how spatial representations develop in navigable environments.
