Guided self-help versus pure self-help for perfectionism: a randomised controlled trial

Perfectionism is known to be a risk factor for the development and maintenance of obsessive-compulsive (OC) and depressive symptoms. The purpose of the present study was to test the effectiveness of a cognitive-behavioural self-help therapy for perfectionism, and to examine the effect of such treatment on OC and depressive symptomatology. The study compares the effectiveness of guided self-help (GSH, n=24) with pure self-help (PSH, n=25) therapy. Both GSH and PSH were found to be effective in reducing perfectionism, and also in reducing OC and depressive symptomatology. Overall, participants in the GSH condition experienced greater symptom improvement than participants in the PSH condition, and treatment gains for both groups were largely maintained at 3-month follow-up. Twenty percent of PSH participants experienced clinically significant increases in depressive symptoms over the treatment and follow-up period (compared to 0% in the GSH condition), suggesting that PSH may be a less suitable strategy than GSH in treating this population. Overall, the findings suggest that self-help for perfectionism is effective in reducing OC and depressive symptomatology in non-clinical individuals, with GSH being superior to PSH.     

Taking Cognitive-Behavior Therapy to School: A School-Based Mental Health Approach

This paper offers an overview using cognitive-behavior therapy (CBT) within a school system. In addition to providing services to individual students, this article provides an overview of implementing CBT into a system of school-wide mental health services. Interventions are discussed at three levels—universal school-wide interventions, target interventions with at-risk students, and intensive interventions with students in need. Examples of specific programs or intervention are given for each level.     

Unconscious semantic priming in the absence of partial awareness

In a recent paper in Psychological Science, Kouider and Dupoux reported obtaining unconscious Stroop priming only when subjects had partial awareness of the masked distractor words (i.e., could consciously perceive subword features that enabled reconstruction of whole words). Kouider and Dupoux conjectured that semantic priming occurs only when such partial awareness is present. The present experiments tested this conjecture in an affective categorization priming task that differed from Kouider and Dupoux’s in using masked distractors that subjects had practiced earlier as visible words. Experiment 1 showed priming from practiced words when subjects had no partial awareness of those words. Experiment 2 showed that, in the absence of partial awareness, practiced words yielded priming but not-practiced words did not. Experiment 3 corroborated Experiment 1 and 2s results using a different test of partial awareness. These results suggest that unconscious processing (rather than partial awareness) of subword elements drives masked semantic priming by practiced words.     

Cognitive Coping Tool Kit for Psychosis: Development of a Group-Based Curriculum

This article outlines an 8-week curriculum that was created to help outpatients develop cognitive and behavioral skills for coping with delusions and hallucinations as well as to reduce patients’ comorbid subjective levels of distress (e.g., depression, anxiety). The manualized protocol consisted of psychoeducation and training in a variety of CBT skills that have shown promise in treating individuals with residual psychosis, using recovery-oriented “naturalistic” methods and culminating in the creation of an individualized “tool kit” of cognitive coping resources. A preliminary study of the effectiveness of this brief group-based CBT program for outpatients with chronic, residual symptoms of schizophrenia was conducted. Participants were 24 outpatients diagnosed with schizophrenia spectrum disorders who were stable on medications and connected to case management community follow-up. The Positive and Negative Syndrome Scale for Schizophrenia interview and the Symptom Checklist-90 self-report symptom scales were administered pre- and post-intervention. The results suggest that there were significant improvements in psychotic symptoms and self-reported distress from pre- to posttreatment.     

Early identification of mental health problems in schools: The status of instrumentation

When embedded within a continuum of mental health services including both prevention and treatment, school-based mental health identification programs can promote improved academic and mental health functioning among students. This article describes the scientific status of assessment instrumentation that may be used for early mental health identification in schools. Currently available instruments are described in terms of their ability to accurately detect youth with mental health problems. Implications for selecting mental health screening and assessment instruments and integrating them into schools are discussed. Finally, a range of approaches to early identification in schools as well as some of the broader ethical and practical issues related to the integration of these strategies into a school-wide continuum of services are presented.     

Second-order conditioning during a compound extinction treatment

Two conditioned taste aversion experiments with rats were conducted to establish if a target taste that had received a prior pairing with illness could be subject to second-order conditioning during extinction treatment in compound with a flavor that also received prior conditioning. In these experiments, the occurrence of second-order conditioning was indicated by protection from extinction of the aversion elicited by the target taste. This possibility, although intuitive, deserves attention because current associative models [e.g., Rescorla, R. A., & Wagner, A. R. (1972). A theory of Pavlovian conditioning: variations in the effectiveness of reinforcement and nonreinforcement. In A. H. Black & W. F. Prokasy (Eds.), Classical conditioning II: Current research and theory (pp. 64-99). New York: Appleton-Century-Crofts.] predict exactly the opposite outcome, namely, that compound extinction of two CSs should result in enhanced extinction.     

Adding up the effects of cultural experience on the brain

How does the brain represent number and perform mathematical calculations? According to a recent and provocative study by Tang and colleagues, it depends on which language you learn. They found that the divergent linguistic and cultural experiences of native Chinese and native English speakers are associated with distinct patterns of brain activity during mathematical processing. Their results raise important questions about the cognitive and neural specificity of cultural influences on mathematical processes and the core nature of mathematical cognition.     

Self-objectification and ideal body shape for men and women

Objectification theory posits that valuing one's body for appearance rather than performance is associated with a range of negative psychological outcomes. This theory has been tested in women, but has received less empirical attention in men. This study examined the relation between self-objectification and ideal body shape in both men and women. One hundred eighty-three college students (111 women, 72 men) completed a questionnaire containing measures of self-objectification and ideal body shape (using a figure array ranging from non-muscular to very muscular). Consistent with hypotheses, women desired a less muscular body and men desired a more muscular body. Women also self-objectified more than men. In addition, there was an interaction between sex and self-objectification on ideal body shape. For women, higher self-objectification scores were related to a desire for a less muscular body. For men, higher self-objectification scores were related to a desire for a more muscular body. Self-objectification theory is a useful framework for understanding body image issues in men. However, the relation between self-objectification and other body related variables may differ for men and women.     

Rationales in children’s causal learning from others’ actions

Shown commensurate actions and information by an adult, preschoolers’ causal learning was influenced by the pedagogical context in which these actions occurred. Four-year-olds who were provided with a reason for an experimenter’s action relevant to learning causal structure showed more accurate causal learning than children exposed to the same action and data accompanied by an inappropriate rationale or accompanied by no explanatory information. These results suggest that children’s accurate causal learning is influenced by contextual factors that specify the instructional value of others’ actions.     

Children's mappings of large number words to numerosities

Previous studies have suggested that children's learning of the relation between number words and approximate numerosities depends on their verbal counting ability, and that children exhibit no knowledge of mappings between number words and approximate numerical magnitudes for number words outside their productive verbal counting range. In the present study we used a numerical estimation task to explore children's knowledge of these mappings. We classified children as Level 1 counters (those unable to produce a verbal count list up to 35), Level 2 counters (those who were able to count to 35 but not 60) and Level 3 counters (those who counted to 60 or above) and asked children to estimate the number of items on a card. Although the accuracy of children's estimates depended on counting ability, children at all counting skill levels produced estimates that increased linearly in proportion to the target number, for numerosities both within and beyond their counting range. This result was obtained at the group level (Experiment 1) and at the level of individual children (Experiment 2). These findings provide evidence that even the least skilled counters do exhibit some knowledge of the form of the mapping between large number words and approximate numerosities.
