A paradoxical dissociation in the effects of midazolam on recollection and automatic processes in the process dissociation procedure

This study used midazolam-induced amnesia to explore the plausibility of the estimates provided by the process dissociation procedure (PDP), which is designed to estimate the contributions of recollection (R) and automatic (A) processes to implicit memory performance. In a double-blind, placebo-controlled, within-subject design with 24 participants, single midazolam doses were administered intravenously, and word stem completion performance was used to calculate PDP estimates. A dissociation was observed such that midazolam decreased R but increased A estimates relative to placebo. Given that a manipulation that induces amnesia would not be expected to facilitate a memory process, these results add to the accumulating body of evidence suggesting that PDP estimates are not always theoretically plausible. Such evidence raises important questions about the use of the PDP.     

THE IMPACT OF THE FEMINIST CRITIQUE ON TESTS, ASSESSMENT, AND ETHODOLOGY

In this article we discuss the implications of the feminist critique for methodologies related to tests and assessment. Several specific examples of the impact (or lack of impact) of feminist thinking on psychological, vocational, and educational tests are provided. From the point of view of a feminist critique, while the revision of the Strong–Campbell Interest Inventory appears to be a success, the 1990 revision of the Minnesota Multiphasic Personality Inventory (MMPI–2) is not. Feminists have inspired methodological improvements such as the use of meta–analysis to evaluate sex difference data and the ability to estimate sampling error to challenge the research on free-response and multiple-choice tests. Recognition of the need to involve women in the development of normative data, introduction of sensitivity reviews, and implementation of differential item functioning analyses have improved tests. However, although testing has improved from the feminist perspective, additional changes can be expected as feminists (female and male) become more involved as scholars and scientists.     

Hand preferences and hand ability in congenitally blind children

Congenitally blind and sighted blindfolded children between the ages of 6 and 14 years were tested for hand preference with performance tasks. There were no differences between the groups in direction or degree of hand preference. The degree of handedness increased with age and was essentially linear though the blind seemed to be somewhat less lateralized at the younger ages.

When the same groups were required to match three-dimensional bricks for height, depth, breadth, and volume, no hand advantages were found for either group. Both groups of children improved in their accuracy of spatial discriminations with age.

Further, the degree of lateralization on the handedness task did not relate to ability on the tactile task or to differences between the right and left hands on the tactile task. Thus, there is no effect of blindness on tactile matching ability nor is there an effect of the hand used in the task.     

An Evaluation of Postvention Following Adolescent Suicide

This study sought to evaluate postvention provided to two schools following student suicides. A risk index for suicidal behavior among exposed adolescents was devised. The index clearly differentiated high (n = 272) and low (n = 534) scorers on a range of outcome variables. While two-thirds of students attending postvention counselling had two or more putative risk factors for suicidal behavior, a further 231 uncounselled students had similar risk scores. Counselled students (n = 63) did not differ from matched controls (n = 63) at 8-month follow-up on a range of outcome variables. Measures to improve future postvention are discussed.     

Self‐concept clarity and relationship satisfaction at the dyadic level

Self‐concept clarity is an individual resource that is associated with couple relationship well‐being. In two dyadic studies, the authors investigated whether and how self‐concept clarity has implications for both partners' relationship satisfaction. Study 1 tested and supported the hypothesis that self‐concept clarity concurrently predicts own and partner's relationship satisfaction through couple identity in a sample of 202 dating couples. Study 2 tested and supported the hypothesis that self‐concept clarity predicts longitudinal change in own and partner's relationship satisfaction through positive (i.e., supportive and common) dyadic coping behaviors in a sample of 97 married couples. The findings clarify and expand the benefits of self‐concept clarity for partners' relational well‐being.     

Testing a dual process model of prejudice: Assessment of group threat perceptions and emotions

Using American college student samples, two studies were conducted to establish the connection between perceptions of threat posed by people of the Muslim world and intergroup emotions toward this group. Study 1, a correlational study, situated these relationships within Duckitt??s (2001) dual process model. Path analyses revealed that perceptions of economic threat from Muslims were predicted by a motivation for hierarchical group relations, as manifested by social dominance orientation. Perceptions of value threat from Muslims were predicted by a motivation for social stability and security, as manifested by right-wing authoritarianism. These economic and value threat perceptions subsequently predicted the intergroup emotions of anger and disgust, respectively. Study 2, an experimental study, involved a manipulation of value threat from Muslims. Results showed that perceiving Muslims to pose a greater threat to Westerners?? values heightened feelings of disgust, which subsequently predicted behavioral inclinations to maintain traditional Western values.     

Does d-Cycloserine Augmentation of CBT Improve Therapeutic Homework Compliance for Pediatric Obsessive–Compulsive Disorder?

Clinical studies in adults and children with obsessive–compulsive disorder (OCD) have shown that d-cycloserine (DCS) can improve treatment response by enhancing fear extinction learning during exposure-based psychotherapy. Some have hypothesized that improved treatment response is a function of increased compliance and engagement in therapeutic homework tasks, a core component of behavioral treatment. The present study examined the relationship between DCS augmented cognitive-behavioral therapy (CBT) and homework compliance in a double-blind, placebo controlled trial with 30 youth with OCD. All children received 10 CBT sessions, the last seven of which included exposure and response prevention paired with DCS or placebo dosed 1 h before the session started. Results suggested that DCS augmented CBT did not predict improved homework compliance over the course of treatment, relative to the placebo augmented CBT group. However, when groups were collapsed, homework compliance was directly associated with treatment outcome. These findings suggest that while DCS may not increase homework compliance over time, more generally, homework compliance is an integral part of pediatric OCD treatment outcome.
