Relationship of Maudsley Obsessional-Compulsive Inventory Subscales with Negative Priming

The relationship between the 4 subscales (Checking, Cleaning, Doubting, Slowness) and total score of the Maudsley Obsessional-Compulsive Inventory (MOCI) and performance in a negative-priming task and a response-speed task in 102 undergraduates was examined. Only Cleaning subscale performance correlated with magnitude of negative priming. Performance on the Checking, Slowing, and Doubting subscales was not significantly related to the magnitude of negative priming. The not significant correlation between Checking score and negative priming magnitude supports the findings of Maki, O'Neill, and O'Neill (1994), who observed that compulsive checking (of, e.g., whether the stove is turned off) appeared to be unrelated to deficiencies in inhibitory control. The present results are not, however, consistent with the view that obsessive-compulsive characteristics (as measured by the MOCI) result in a disruption in and a reduction of inhibitory control (Enright & Beech, 1993).     

Shifts in Women’s Mate Preferences Across the Ovulatory Cycle: A Critique of Harris (2011) and Harris (2012)

Many studies have documented systematic shifts in women’s mate preferences and sexual motivations across the ovulatory cycle. Harris (2012) presents a nonreplication of one particular finding in this literature—namely, that women’s preference for masculinity in men’s faces shifts across the cycle. Harris critiques the empirical and theoretical literature on cycle shifts and concludes that the cycle shift hypothesis should be abandoned. Here, we situate Harris’s findings within the broader empirical literature and respond to several of the points in her critique. We conclude that the evidence for cycle shifts in women‘s mate preferences and sexual motivations is much stronger than Harris portrays and that she mischaracterizes the theoretical basis of this work.     

Why Teach Literature and Medicine? Answers from Three Decades

In this essay, I look back at some of the earliest attempts by the first generation of literature-and-medicine scholars to answer the question: Why teach literature and medicine? Reviewing the development of the field in its early years, I examine statements by practitioners to see whether their answers have held up over time and to consider how the rationales they articulated have expanded or changed in the following years and why. Greater emphasis on literary criticism, narrative ethics, narrative theory, and reflective writing has influenced current work in the field in ways that could not have been foreseen in the 1970s. The extraordinary growth of interest and work in the field nationally and, especially since 1996, internationally has included practitioners in many additional areas such as disability studies, film studies, therapeutic writing, and trauma studies. Along with the emergence of narrative medicine, this diverse community of scholars and practitioners—affiliated more through their use of narrative methodologies than the teaching of literature—makes the perennial challenge of evaluation and assessment even more complicated.     

Evaluating the random representation assumption of lexical semantics in cognitive models

A common assumption implicit in cognitive models is that lexical semantics can be approximated by using randomly generated representations to stand in for word meaning. However, the use of random representations contains the hidden assumption that semantic similarity is symmetrically distributed across randomly selected words or between instances within a semantic category. We evaluated this assumption by computing similarity distributions for randomly selected words from a number of well-known semantic measures and comparing them with the distributions from random representations commonly used in cognitive models. The similarity distributions from all semantic measures were positively skewed compared with the symmetric normal distributions assumed by random representations. We discuss potential consequences that this false assumption may have for conclusions drawn from process models that use random representations.     

Relax and try this instead: abbreviated habit reversal for maladaptive self-biting.

We evaluated the effectiveness of an abbreviated habit reversal procedure to reduce mal-adaptive oral self-biting in an adolescent boy in residential care. Treatment involved a combination of relaxation and two competing responses. Results of a withdrawal design and two posttreatment medical evaluations indicated that the intervention eliminated the biting and the tissue damage it caused.     

A PRELIMINARY ANALYSIS OF INTERACTIVE EFFECTS BETWEEN COMMON CLASSROOM CONTINGENCIES AND METHYLPHENIDATE

To assess the drug—behavior interaction effects with an 8-year-old boy with attention deficit hyperactivity disorder, common classroom antecedent (e.g., seating arrangement) and consequent (e.g., peer prompts) stimuli were alternated within a school day while drug conditions (methylphenidate vs. placebo) were alternated across days. The results suggested that peer attention maintained disruptive behavior when methylphenidate was absent but not when it was present.     

Improving psychological adjustment following a first episode of psychosis: A randomised controlled trial of cognitive therapy to reduce post psychotic trauma symptoms

There are few evaluated psychological interventions or theoretical approaches which are specifically aimed at reducing problems related to adjustment and adaptation following a first episode of psychosis. The present study tests the efficacy of a form of CBT (Cognitive Recovery Intervention; CRI) in reducing trauma, depression and low self esteem following a first episode of psychosis, in a single-blind randomised controlled trial. A total of 66 patients who had recently experienced a first episode of psychosis were randomly assigned to CRI or treatment as usual (TAU) and followed up at 6 and 12 months. People receiving CRI tended to have lower levels of post-intervention trauma symptoms and demonstrated greater improvement than those receiving TAU alone. This was especially the case at 6 months for those with high pre-treatment levels of trauma. There was, however, no advantage for the CRI group with regards to reduced depression or improved self esteem. In conclusion, CRI appears to be an effective intervention to help young people adapt to the traumatic aspects of a first episode of psychosis although further evaluation in a larger study is warranted.     

Concurrent and longitudinal effects of ethnic identity and experiences of discrimination on psychosocial adjustment of Navajo adolescents

In this study, we examined concurrent and longitudinal relations among Navajo adolescents' ethnic identity, experiences of discrimination, and psychosocial outcomes (i.e., self-esteem, substance use, and social functioning). At Time 1, 137 Navajo adolescents (67 male, 70 female), primarily in Grades 9 and 10, completed a written survey assessing ethnic identity, discrimination experiences, and a range of internalizing and externalizing behaviors. Two years later, 92 participants completed the same survey again. Ethnic and cultural identification was assessed via the Multiethnic Ethnic Identity Measure (MEIM; Phinney, 1992) and the Orthogonal Cultural Identification Scale (OCIS; Oetting & Beauvais, 1990). At Time 1, MEIM Affirmation and Belonging, MEIM Exploration, and OCIS White American identification all demonstrated strong, positive associations with adaptive functioning for male and female adolescents, whereas discrimination experiences were linked to lower self-esteem and social functioning for male adolescents. By Time 2, fewer significant concurrent associations between ethnic identity and psychosocial functioning scores remained, and discrimination experiences emerged as the most consistent correlate of poorer psychosocial functioning for male adolescents. Controlling for Time 1 psychosocial functioning, relatively few direct effects of ethnic and cultural identification variables predicted psychosocial functioning longitudinally, but discrimination experiences demonstrated strong and consistent longitudinal links with boys' substance use. Finally, interaction effects assessing the moderating influence of ethnic and cultural identification on negative links between discrimination and psychosocial functioning suggested that embeddedness in and connection to Navajo culture and, in some cases, connection to White American culture, served as a buffer to the negative effects of discrimination experiences.
