Neuropsychological Functioning and Recall of Research Consent Information Among Drug Court Clients

Evidence suggests that research participants often fail to recall much of the information provided during the informed consent process. This study was conducted to determine the proportion of consent information recalled by drug court participants following a structured informed consent procedure and the neuropsychological factors that were related to recall. Eighty-five participants completed a standard informed consent procedure to participate in an ongoing research study, followed by a 17-item consent quiz and a brief neuropsychological battery 2 weeks later. Participants performed within the normal range on most of the neuropsychological measures, although roughly one third showed deficits on measures of executive functioning. Participants failed to recall over 65% of the consent information within 2 weeks of entering the study, and their recall was significantly correlated with verbal IQ, drug problem severity, reading ability, memory, and attention. These factors may be useful in determining whether research participants require enhanced consent procedures.     

The Lessons of the Development of the First APA Ethics Code: Blending Science,Practice, and Politics

The Ethics Code of the American Psychological Association (APA) is a bedrock of the profession. The contextual factors of society affect the Ethics Code of the APA, resulting in an ever-changing document. The context of the reorganization of the APA after World War II created an initial impetus toward a formalized code. A key contextual feature of the Code's development was the use of the Critical Incident Technique, which was based in the empirical aspirations of the psychological field. This article explores the historical context around the APA's decision to draft an ethics code, reviews its development, and discusses its role for psychologists today.     

Working memory dynamics bias the generation of beliefs: The influence of data presentation rate on hypothesis generation

Although temporal dynamics are inherent aspects of diagnostic tasks, few studies have investigated how various aspects of time course influence hypothesis generation. An experiment is reported that demonstrates that working memory dynamics operating during serial data acquisition bias hypothesis generation. The presentation rate (and order) of a sequence of serially presented symptoms was manipulated to be either fast (180 ms per symptom) or slow (1,500 ms per symptom) in a simulated medical diagnosis task. When the presentation rate was slow, participants chose the disease hypothesis consistent with the symptoms appearing later in the sequence. When the presentation rate was fast, however, participants chose the disease hypothesis consistent with the symptoms appearing earlier in the sequence, therefore representing a novel primacy effect. We predicted and account for this effect through competitive working memory dynamics governing information acquisition and the contribution of maintained information to the retrieval of hypotheses from long-term memory.     

Early Predictors of Urban Adolescents’ Community Violence Exposure

This study examined the extent to which individual, peer, and family factors predicted the onset of community violence exposure in middle and high school, as well as the indirect effects of early factors. We were particularly interested in the timing of exposure to community violence during adolescence, and thus conducted survival analyses on data from 632 urban youth, followed from first grade through high school. Early aggressive behavior and poor academic readiness were associated with an earlier onset of community violence exposure in adolescence. The effects of early aggression on community violence exposure and victimization were accounted for, in part, by peer rejection and deviant peer affiliation; there was no evidence of moderation by gender or parental monitoring. Findings highlight potential targets for preventive interventions with youth at risk of community violence exposure.     

Divided attention: An undesirable difficulty in memory retention

How can we improve memory retention? A large body of research has suggested that difficulty encountered during learning, such as when practice sessions are distributed rather than massed, can enhance later memory performance (see R. A. Bjork & E. L. Bjork, 1992). Here, we investigated whether divided attention during retrieval practice can also constitute a desirable difficulty. Following two initial study phases and one test phase with Swahili–English word pairs (e.g., vuvi–snake), we manipulated whether items were tested again under full or divided attention. Two days later, participants were brought back for a final cued-recall test (e.g., vuvi–?). Across three experiments (combined N = 122), we found no evidence that dividing attention while practicing retrieval enhances memory retention. This finding raises the question of why many types of difficulty during practice do improve long-term retention, but dividing attention does not.     

Sailing between Scylla and Charybdis1: Incorporating qualitative approaches into child psychotherapy research

Starting from the acknowledged gap between research and practice in child psychotherapy, this paper offers an historical perspective on the relation between these two activities, and suggests that qualitative approaches to research may offer new ways of bringing them together. After introducing the fundamental concepts of qualitative analysis, three areas where qualitative forms of research may be useful to child psychotherapists are explored: relevant but non-psychotherapy research; accounts of therapy research; and therapy process research. Examples of all of these types of research are presented, and some of the challenges to incorporating qualitative approaches into child psychotherapy research are discussed.     

Simulated Visual Field Loss Does Not Alter Turning Coordination in Healthy Young Adults

Turning, while walking, is an important component of adaptive locomotion. Current hypotheses regarding the motor control of body segment coordination during turning suggest heavy influence of visual information. The authors aimed to examine whether visual field impairment (central loss or peripheral loss) affects body segment coordination during walking turns in healthy young adults. No significant differences in the onset time of segments or intersegment coordination were observed because of visual field occlusion. These results suggest that healthy young adults can use visual information obtained from central and peripheral visual fields interchangeably, pointing to flexibility of visuomotor control in healthy young adults. Further study in populations with chronic visual impairment and those with turning difficulties are warranted.     

Young adult e-cigarette users’ reasons for liking and not liking e-cigarettes: A qualitative study

Objective: To gain an in-depth understanding of what young adult electronic- or e-cigarette users like or dislike about e-cigarettes. We aimed to determine the reasons that may encourage young adults to use e-cigarettes or discourage them from using e-cigarettes.

Design: Twelve focus group discussions were conducted with 62 current daily e-cigarette users (63% men) of mean age = 25.1 years (standard deviation = 5.5). Data were analysed following principles of inductive content analysis.

Results: Results indicated 12 categories of reasons for liking e-cigarettes (e.g. recreation, smoking cessation) and 6 categories of reasons for not liking e-cigarettes (e.g. poor product quality, poor smoking experience).

Conclusions: Young adults’ motives for using or not using e-cigarettes appear to be varied and their relative importance in terms of predicting e-cigarette use initiation, dependence, and cigarette/e-cigarette dual use needs to be carefully studied in population-based, empirical studies. The current findings suggest that e-cigarettes may serve social, recreational, and sensory expectancies that are unique relative to cigarettes and not dependent on nicotine. Further, successful use of e-cigarettes in smoking cessation will likely need higher standards of product quality control, better nicotine delivery efficiency and a counselling component that would teach smokers how to manage e-cigarette devices while trying to quit smoking cigarettes.     

Memory for Faces in Children with Autism

Previous research has established that children with Autistic Disorder have deficits in aspects of social cognition and in verbal memory, but research on social memory is limited. Twenty-four autistic boys aged 7 to 12 years and normal controls matched for verbal mental age were administered parallel social and nonsocial matching and memory tasks. Results showed that the children with autism were impaired relative to the normal children on the social (face) memory task only. Furthermore, of the four experimental tasks, the social memory task had the highest and most consistent correlations with measures of social development and adaptive skills. Whereas the normal children used the special status of faces to recall them more easily than objects, the children with autism showed equal recall of objects and faces.
