Concreteness and item-to-list context associations in the free recall of items differing in context variability

Context variability can be defined as the number of preexperimental contexts in which a given concept appears. Following M. Steyvers and K. J. Malmberg's (2003) work, the authors have shown that concepts that are experienced in fewer preexperimental contexts generally are better remembered in episodic memory tasks than concepts that are experienced in a greater number of preexperimental contexts. The purpose of this article is to demonstrate that low context variability confers its memorial advantage because of stronger item-to-list context associations as compared with high context variability. Three experiments that use environmental context changes from study to test demonstrate that the low context variability advantage is eliminated when item-to-list context associations are not available because of environmental changes at test. In addition, the low context variability advantage is eliminated when inward processing at study prevents the formation of item-to-list context associations.     

Task-set inertia and memory-consolidation bottleneck in dual tasks

Three dual-task experiments examined the influence of processing a briefly presented visual object for deferred verbal report on performance in an unrelated auditory-manual reaction time (RT) task. RT was increased at short stimulus-onset asynchronies (SOAs) relative to long SOAs, showing that memory consolidation processes can produce a functional processing bottleneck in dual-task performance. In addition, the experiments manipulated the spatial compatibility of the orientation of the visual object and the side of the speeded manual response. This cross-task compatibility produced relative RT benefits only when the instruction for the visual task emphasized overlap at the level of response codes across the task sets (Experiment 1). However, once the effective task set was in place, it continued to produce cross-task compatibility effects even in single-task situations (“ignore” trials in Experiment 2) and when instructions for the visual task did not explicitly require spatial coding of object orientation (Experiment 3). Taken together, the data suggest a considerable degree of task-set inertia in dual-task performance, which is also reinforced by finding costs of switching task sequences (e.g., AC → BC vs. BC → BC) in Experiment 3.     

Minority students of color and the psychology graduate pipeline: disquieting and encouraging trends, 1989-2003

Trends since 1989 in the minority graduate pipeline in psychology are examined, with special focus on trends in recent years. Encouraging trends generally outweigh troubling ones at lower levels of the pipeline. However, in recent years disquieting trends dominate at the higher pipeline levels. Promising trends include a rise in the percentage (to nearly 25%) of minority psychology students receiving the bachelor's degree and a rise to more than 20% receiving the master's degree. Troubling trends include the stalling of growth in minority PhD degree receipt since 1999 and the lack of growth in the percentage of African American and Hispanic/Latino(a) students entering PhD departments. Given the mixed findings, one of the highest priorities for psychology must be continued and persistent efforts to develop practices and policies that enhance recruitment, high levels of achievement, and degree receipt for students of color.     

The effect of contingent reinforcement on target variables in outpatient psychotherapy for depression: a successful and unsuccessful case using functional analytic psychotherapy

The current study investigated a behavior-analytic treatment, functional analytic psychotherapy (FAP), for outpatient depression utilizing two single-subject A/A+B designs. The baseline condition was cognitive behavioral therapy. Results demonstrated treatment success in 1 client after the addition of FAP and treatment failure in the 2nd. This study highlights the challenges in measuring treatment progress and outcome idiographically in this population.     

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.     

Parents' and teachers' concordance with children's self-ratings of suicidality: findings from a high-risk sample

This study examined concordance between adult and child reports of child suicidality using a sample of 1,046 8-year-old children at risk for, or having experienced, maltreatment. Concordance was low with both caregivers and teachers. For children reporting no suicidality, caregiver-child agreement was associated with few transitions in caregiver and low social withdrawal and aggression, and teacher-child agreement was associated with non-White ethnicity, good academic performance, and low thought problems. For children reporting suicidality, care-giver-child agreement was associated with perceptions of child mental health needs, aggression, and somatic complaints, and teacher-child agreement was associated with thought problems.     

Warning signs for suicide: theory, research, and clinical applications

The current article addresses the issue of warning signs for suicide, attempting to differentiate the construct from risk factors. In accordance with the characteristic features discussed, a consensus set of warning signs identified by the American Association of Suicidology working group are presented, along with a discussion of relevant clinical and research applications.     

Outcome of patients rehabilitated through a New Zealand forensic psychiatry service: A 7.5 year retrospective study

This paper describes a 7.5 year retrospective study of all patients discharged from inpatient forensic services to forensic community team (FCT) follow-up from the Auckland Regional Forensic Psychiatry Service. Patients' files were studied for clinical, criminal, and risk data, type of service delivered, and final level of function achieved in the community. Rearrest, re-hospitalization, and reimprisonment data were obtained from clinical, court, and prison records.105 patients were included. The most common diagnosis was a psychotic disorder, and index offending behaviour was typically violent. The median period of inpatient stay was 36 months and mean subsequent FCT follow-up 21.7 months (SD 17.8). The majority of patients were from Maori and Pacific Island ethnic groups. At the end of the study, half were in independent living, half were in some form of employment, and 19% were readmitted to a forensic hospital.One patient was rearrested but not reimprisoned whilst under forensic community team care. However, 9 of the 48 who were discharged to general mental health services were rearrested and 5 reimprisoned. Only two offences were as serious as the original index offence.Broad based assertive, mandated, and committed forensic rehabilitation can achieve high quality outcomes. These levels of function may not be sustained under less assertive care.     

The prepared mind: neural activity prior to problem presentation predicts subsequent solution by sudden insight

Insight occurs when problem solutions arise suddenly and seem obviously correct, and is associated with an "Aha!" experience. Prior theorizing concerning preparation that facilitates insight focused on solvers' problem-specific knowledge. We hypothesized that a distinct type of mental preparation, manifested in a distinct brain state, would facilitate insight problem solving independently of problem-specific knowledge. Consistent with this hypothesis, neural activity during a preparatory interval before subjects saw verbal problems predicted which problems they would subsequently solve with, versus without, self-reported insight. Specifically, electroencephalographic topography and frequency (Experiment 1) and functional magnetic resonance imaging signal (Experiment 2) both suggest that mental preparation leading to insight involves heightened activity in medial frontal areas associated with cognitive control and in temporal areas associated with semantic processing. The results for electroencephalographic topography suggest that noninsight preparation, in contrast, involves increased occipital activity consistent with an increase in externally directed visual attention. Thus, general preparatory mechanisms modulate problem-solving strategy.     

Personality, biographical characteristics, and job interview success: a longitudinal study of the mediating effects of interviewing self-efficacy and the moderating effects of internal locus of causality

In this study, the authors developed and tested a model of performance in job interviews that examines the mediating role of interviewing self-efficacy (I-SE; job applicants' beliefs about their interviewing capabilities) in linking personality and biographical background with interview success and the moderating role of locus of causality attributions in influencing the relationship between interview success and subsequent I-SE. The authors tested their model (over 5 months' duration) with matched data from 229 graduating seniors, firms, and university records. Hierarchical regression analyses demonstrated I-SE mediated the effects of Extraversion, Conscientiousness, and leadership experience on interview success. Locus of causality attributions for interview outcomes moderated the relationship between interview success and subsequent I-SE. Theoretical and practical implications are discussed.
