Psychological impact of benign breast biopsy: a longitudinal, comparative study.

The impact of benign breast biopsy (BBB) on distress and perceptions of risk for breast cancer (BC) was examined. Interviews were conducted with 100 women shortly after notification of biopsy results and 4 and 8 months post-BBB. Compared with matched healthy comparison (HC) women without BBB, the BBB group evidenced greater BC-specific distress at baseline. BC-specific distress declined after BBB, remaining elevated relative to the HC group at the 8-month follow-up. Dispositional (optimism, informational coping style), demographic (education), clinical (family history of BC), and cognitive (BC risk perception) variables were associated with baseline levels of BC-specific distress or persistence of distress. Results support the monitoring process model (S. M. Miller, 1995) and the cognitive social health information processing model (S. M. Miller, Y. Shoda, & K. Hurley, 1996).     

There are many ways to be rich: Effects of three measures of semantic richness on visual word recognition

Previous studies have reported that semantic richness facilitates visual word recognition (see, e.g., Buchanan, Westbury, & Burgess, 2001; Pexman, Holyk, & Monfils, 2003). We compared three semantic richness measures--number of semantic neighbors (NSN), the number of words appearing in similar lexical contexts; number of features (NF), the number of features listed for a word's referent; and contextual dispersion (CD), the distribution of a word's occurrences across content areas-to determine their abilities to account for response time and error variance in lexical decision and semantic categorization tasks. NF and CD accounted for unique variance in both tasks, whereas NSN accounted for unique variance only in the lexical decision task. Moreover, each measure showed a different pattern of relative contribution across the tasks. Our results provide new clues about how words are represented and suggest that word recognition models need to accommodate each of these influences.     

Group Intensive Family Training (GIFT) for preschoolers with autism spectrum disorders

Early, intensive behavioral intervention is effective in treating children with autism spectrum disorders (ASDs), but can be cost prohibitive. Expenses may be defrayed if children can benefit from parents acting as therapists. This quantitative case series examines the efficacy of the Group Intensive Family Training (GIFT) program, a 12‐week (180 h, delivered 3 h each weekday) parent‐training for preschoolers with ASDs. Parents were individually mentored in the hands‐on application of behavior analytic techniques, implementing these skills in vivo within a group of six parent–child dyads. Seventy‐two parents and children (ages 25–68 months) with ASDs participated in this study. Children's cognitive and adaptive functioning was assessed before and after the intervention program. Analyses revealed average gains of eight standard score points on the Mullen Early Learning Composite and five standard score points on the Vineland Adaptive Behavior Composite after 12 weeks of treatment. Additionally, 14% and 11% of the children moved from the ‘impaired’ to ‘non‐impaired’ range on Mullen and Vineland composite scores, respectively. This preliminary investigation suggests that GIFT's behavioral, group parent‐training can lead to significant, yet cost‐ and time‐efficient gains for children with ASDs. Results must be interpreted with caution because of the absence of a control group. Copyright © 2008 John Wiley & Sons, Ltd.     

The thrust of the problem: bodily inhibitions and guilt as a function of mortality salience and neuroticism

We argue that existential concerns underlie discomfort with the physicality of the body and that activities likely to make individuals aware of their physical body (e.g., sex, dancing) may be inhibited and cause guilt. Further, individuals high in neuroticism may be especially vulnerable to such difficulties. To test this, individuals high and low in neuroticism were primed with thoughts about their mortality or a control topic and then engaged in an exercise designed to promote body awareness before self-reporting guilt. A comparison group engaged in non-body-oriented behavior. The results revealed that high neuroticism participants inhibited their body-oriented behavior when mortality was salient and that they experienced a marginal increase in guilt after performing the behavior in conjunction with mortality salience. Discussion focuses on the relationship between neuroticism, mortality salience, inhibition surrounding the body, and guilt.     

Terror management and adults' attachment to their parents: the safe haven remains

Six studies examined the role of young adults' parental attachment in terror management. Studies 1-3 revealed that activating thoughts of one's parent in response to mortality salience (MS) reduced death-thought accessibility and worldview defense and increased feelings of self-worth. Studies 4-5 demonstrated that MS led to greater ease of recalling positive maternal interactions and greater difficulty recalling negative interactions, and increased attraction to a stranger who was described as being similar to one's parent. If reliance on parents for terror management purposes reflects the operation of attachment mechanisms, then such effects should vary on the basis of an individual's attachment style. Study 6 demonstrated that, after MS, insecure individuals were more likely to rely on relationships with their parents, whereas secure individuals were more likely to rely on relationships with romantic partners.     

Forms of Aggression and Peer Victimization During Early Childhood: A Short-term Longitudinal Study

A multi-informant and multi-measure short-term longitudinal study of the association between subtypes of aggression and peer victimization was conducted in an early childhood sample (M = 44.36 months; SD = 11.07; N = 120). Observational and teacher report measures demonstrated appropriate reliability and validity as well as stability across an academic year. Concurrent associations revealed that observed relational aggression was uniquely associated with teacher reported relational victimization and observed physical aggression was uniquely associated with teacher reported physical victimization. Prospective findings indicated that observed relational aggression predicted increases in teacher reported relational victimization for girls only, controlling for the variance associated with physical aggression, prosocial behavior, physical victimization, and gender. Peer rejection partially mediated the association between observed relational aggression at time 1 and teacher reported relational victimization at time 2. Ways in which these and other prospective findings extend the extant literature are discussed.     

The life and death of creativity: The effects of mortality salience on self versus social-directed creative expression

Research in terror management theory suggests that our connections to others function, in part, to provide protection from the anxiety associated with the awareness of inevitable death. The individuating nature of creative expression can potentially undermine these connections, making creativity particularly problematic when one is dealing with mortality concerns. Consistent with this, a number of findings have elucidated emotional consequences associated with creativity when mortality concerns are active. However, to date, research has not focused on how mortality awareness may impact levels of creativity. The present study assessed the hypothesis that mortality concerns will inhibit creative behavior that threatens social connections but will not undermine and may even facilitate creative behavior that bolsters social connections. The results showed that amplified concerns about mortality decreased creativity when the act was self-directed but not when it was community-directed. Theoretical implications and future directions are discussed.     

Measuring incremental changes in word knowledge: Experimental validation and implications for learning and assessment

The goal of this study was to test a new technique for assessing vocabulary development. This technique is based on an algorithm for scoring the accuracy of word definitions using a continuous scale (Collins-Thompson & Callan, 2007). In an experiment with adult learners, target words were presented in six different sentence contexts, and the number of informative versus misleading contexts was systematically manipulated. Participants generated a target definition after each sentence, and the definition-scoring algorithm was used to assess the degree of accuracy on each trial. We observed incremental improvements in definition accuracy across trials. Moreover, learning curves were sensitive to the proportion of misleading contexts, the use of spaced versus massed practice, and individual differences, demonstrating the utility of this procedure for capturing specific experimental effects on the trajectory of word learning. We discuss the implications of these results for measurement of meaning, vocabulary assessment, and instructional design.     

The pathophysiology of body dysmorphic disorder

Body dysmorphic disorder (BDD) is an often severe and disabling condition, affecting up to 2% of the population. Despite its prevalence and clinical significance, very little is known about the pathophysiology of BDD. However, clues to its possible neurobiological substrates and abnormalities in information processing are starting to emerge. This article reviews findings from genetic, brain lesion, neuroimaging, neuropsychological, and psychopharmacological studies that have allowed us to develop a tentative model of the functional neuroanatomy of BDD. There is likely a complex interplay of dysfunctions in several brain networks underlying the pathophysiology of BDD. A combination of dysfunctions in frontal-subcortical circuits, temporal, parietal, and limbic structures, and possibly involving hemispheric imbalances in information processing, may produce both the characteristic symptoms and neurocognitive deficits seen in BDD. An improved understanding of the pathophysiology of BDD will be crucial to guide the development of better treatments.
