Dissociative tendencies and memory performance on directed-forgetting tasks

The current article presents two studies that aimed to replicate DePrince and Freyd's (2001, 2004) studies demonstrating that high and low dissociators differentially recall neutral and trauma words under conditions of varying cognitive load. We did not find this effect. This lack of replication was apparent for both free recall and word recognition memory and in both studies. In effect, we found little evidence to support betrayal trauma theory, yet observed increased memory fallibility, as demonstrated by lower general recall and (in one study) commission errors, in high dissociators.     

Neurocognitive Effects of Methamphetamine: A Critical Review and Meta-analysis

This review provides a critical analysis of the central nervous system effects of acute and chronic methamphetamine (MA) use, which is linked to numerous adverse psychosocial, neuropsychiatric, and medical problems. A meta-analysis of the neuropsychological effects of MA abuse/dependence revealed broadly medium effect sizes, showing deficits in episodic memory, executive functions, information processing speed, motor skills, language, and visuoconstructional abilities. The neuropsychological deficits associated with MA abuse/dependence are interpreted with regard to their possible neural mechanisms, most notably MA-associated frontostriatal neurotoxicity. In addition, potential explanatory factors are considered, including demographics (e.g., gender), MA use characteristics (e.g., duration of abstinence), and the influence of common psychiatric (e.g., other substance-related disorders) and neuromedical (e.g., HIV infection) comorbidities. Finally, these findings are discussed with respect to their potential contribution to the clinical management of persons with MA abuse/dependence.     

Triangulation mobility of auto‐theft offenders

This research paper presents an examination of the journey to and from crime for auto‐theft offenders in the UK. For 852 offences, ‘wheel’ distances are calculated for triangles formed by offenders' home location, theft location, and vehicle disposal location. The study demonstrates typical isosceles mobility triangles; distances travelled to and from home locations are roughly equal, whereas distances between theft and disposal points were shorter. Distances travelled by offenders under 17 years old and offences involving drug and drink were shown to be shorter than comparison groups. Prolific offenders tend to travel further, although there is significant variation in this subgroup. Explanations and implications are discussed. Copyright © 2008 John Wiley & Sons, Ltd.     

Self-analysis and post-termination improvement after psychoanalysis and long-term psychotherapy

Long-term follow-up studies of long-term psychoanalytically oriented psychotherapy or psychoanalysis are extremely rare, and few have focused on the post-treatment process itself. In the Stockholm Outcome of Psychoanalysis and Psychotherapy project, one of the results was that patients in psychoanalysis continued to improve after termination to a higher degree than patients in long-term psychotherapy. In this study 20 patients selected from the project were interviewed on two occasions, one and two years after termination, in order to explore how they described their post-treatment processes. The interviews were studied qualitatively using a multiple case study design, and categories of different types of post-treatment development were created from these case studies. Results indicate that the variation within treatment groups is large, and that development may continue in several ways after termination. The most striking difference between psychoanalysis and psychotherapy was not, as hypothesized, in the self-analytic function, but in various self-supporting strategies described by former analysands but not by former psychotherapy patients. However, only self-analysis was significantly correlated with post-termination improvement across both treatments. Three patients improving after termination and three deteriorating are described in detail as illustrations. Some methodological constraints of the design limit the generalizeability of results.     

Is the delay discounting paradigm useful in understanding social anxiety?

The delay discounting paradigm was used to examine its utility in understanding motivational factors among socially anxious individuals. Participants (n=88) who reported high and low levels of social anxiety were randomly assigned to either a social threat or non-threat condition and their subsequent rates of discounting were examined. A significant difference in rates of discounting was found between the high and low social anxiety groups within the non-threat condition, with high social anxiety participants showing increased discounting. This study suggests that a modified version of the delay discounting paradigm may be useful in understanding motivational factors in social anxiety.     

The effectiveness of sentence cues in measuring the Big Three motives

Despite the popularity of free response measures in the motivation literature, research geared toward the development of a standard battery of cues for measuring the Big Three motives (achievement, affiliation, power) has been lacking. The current research examined the effectiveness of sentence cues in eliciting motive imagery in two studies (students, entrepreneurs) comprising 242 men and women. Results indicated that sentence cues were effective in eliciting achievement and affiliation imagery, but not power imagery. In addition, an examination of the subcategories underlying each motive scoring system indicated that there were several infrequently scored subcategories in the achievement and power motive scoring systems that could be considered for removal.     

Depression and distress predict time to cardiovascular disease in dementia caregivers.

OBJECTIVE: This study assessed the impact of depressive symptoms and distress from patient problem behaviors on time to developing a diagnosis of cardiovascular disease (CVD) in a sample of 643 dementia family caregivers. DESIGN: A longitudinal, prospective design was used. Over an 18-month period, caregivers free from a CVD diagnosis at baseline were assessed at 6, 12, and 18-month follow-ups for the onset of CVD. MAIN OUTCOME MEASURES: Days to the onset of CVD was the primary outcome. RESULTS: Over the length of the study, 32 participants (5%) reported a diagnosis of CVD. After adjusting for sociodemographic and health factors (e.g., high blood pressure, age, smoking history), greater depressive symptoms (p = .040) and distress from patient problem behaviors (p = .034) were significant predictors of time to CVD diagnosis. CONCLUSION: This study suggests that increased depressive symptoms and reaction to patient problem behaviors (i.e., distress) may increase caregivers' risk for experiencing negative health outcomes, specifically CVD.     

Children's explanations of the intentions underlying others' behaviour

This study investigated developmental differences in children's explanations of the intentions underlying the behaviours of others, including behaviours that conflicted with their expectations. Children aged 6–13 and adults explained the intentions underlying their predictions of behaviour following stories with ambiguous, positive, and negative cues. Children were then presented with experimenter–provided conflicting behaviour and explained again. Results indicated that with no clear cues, children and adults had optimistic expectations. When cues were provided, participants across development provided explanations consistent with positive cues, but children under age 10 were reluctant to provide explanations consistent with negative cues, despite good recall. When explaining conflicting behaviour, people may hesitate to overlook suspicions of negative intent sometimes even in the face of good behaviour, and this reluctance may increase with age. Findings suggest we may all overcome an optimistic bias, but children under age 10 may struggle more to do so.
