You don't know me, but I know you: the illusion of asymmetric insight

People, it is hypothesized, show an asymmetry in assessing their own interpersonal and intrapersonal knowledge relative to that of their peers. Six studies suggested that people perceive their knowledge of their peers to surpass their peers' knowledge of them. Several of the studies explored sources of this perceived asymmetry, especially the conviction that while observable behaviors (e.g., interpersonal revelations or idiosyncratic word completions) are more revealing of others than self, private thoughts and feelings are more revealing of self than others. Study 2 also found that college roommates believe they know themselves better than their peers know themselves. Study 6 showed that group members display a similar bias-they believe their groups know and understand relevant out-groups better than vice versa. The relevance of such illusions of asymmetric insight for interpersonal interaction and our understanding of "naive realism" is discussed.     

New Zealand Maori and European mothers and their 3-year-old children: Interactive behaviors in pre-school settings

The interactive behaviors used by 34 indigenous Polynesian and 41 European mothers were observed during spontaneous play sessions at New Zealand pre-schools. Mothers from higher and lower education-level backgrounds were included in each of the two ethnic groups and the mothers were videotaped with their 3-year-old sons or daughters. Maternal interactive behaviors were subsequently coded using Zegiob and Forehand's (1975) measure. Overall, the incidence of maternal interactions in command form was high. Marked individual differences within groups, and some important between-group differences, were evident on several behaviors, but child gender was not associated with major variations in maternal interactive behavior. The results affirmed, in the New Zealand context, the association between mothers' education levels and their interactive behavior, and here, the control of maternal education level and type of pre-school attended worked against “deficit” interpretations.     

Psychopathy and the Five Factor Model in a Noninstitutionalized Sample: A Domain and Facet Level Analysis

The relationship of primary and secondary psychopathic dispositions as measured by the Levenson Self-Report Psychopathy (LSRP) Scales to NEO-PI-R domain and facet scales of the Five Factor Model (FFM) was examined in a sample (N = 463) of young adults. Previous investigations were extended by (1) addressing the relationship of higher- (i.e., domain) and lower-order (i.e., facet) FFM traits to primary and secondary psychopathy in noninstitutionalized persons, in an attempt to validate hypotheses by T. A. Widiger and D. R. Lynam (1998); (2) examining sex differences in FFM traits in relation to these two psychopathic dispositions; and (3) lending further evidence for the validity of the LSRP. LSRP primary psychopathy was marked by low Agreeableness whereas LSRP secondary psychopathy was characterized by high Neuroticism, low Agreeableness, and low Conscientiousness. Although few sex differences were found between primary and secondary psychopathy, findings support the use of NEO-PI-R domain and facet scales in the identification of personality disorder.     

Plasticity for recovery, plasticity for development: cognitive outcome in twins discordant for mid-childhood ischemic stroke.

Cognitive and language profiles in a set of likely monozygotic 13-year-old twins raised together and discordant for an extensive left hemisphere stroke are described 6 years post-stroke. Recovery differed across four skill profiles, created based on a model of plasticity. Full recovery of lost skills and full or partial development of new skills typically involved either semantic memory or right hemisphere lateralized functions such as visual perception skills. Limited development of new skills and full or partial recovery of lost skills took place in either active verbal memory or oral language skills that are left hemisphere lateralized. Language skills concerned with real-time lexical retrieval, or the use and understanding of morphology and grammar, phonological processing skills, and auditory working memory were least likely to recover and continue to develop.     

Body Dysmorphic Disorder among Diverse Racial/Ethnic and Sexual Orientation Groups: Prevalence Estimates and Associated Factors

Body Dysmorphic Disorder (BDD) is a psychological disorder characterized by excessive appearance concerns. This cross-sectional study assessed an undergraduate sample of 1,041 participants from a southeastern American university to estimate an overall prevalence of BDD; investigate differences by gender, race/ethnicity, and sexual orientation; and also examine the contributions of other related constructs including appearance comparison, obligatory exercise, body image disturbance, and self-esteem. Results indicated an overall prevalence of 4.9%. Women endorsed more symptoms of BDD than men, among women Caucasians and Latinas endorsed more symptoms than African Americans, and sexual minorities endorsed more symptoms than heterosexuals. Overall, BDD symptomatology was negatively correlated with body satisfaction and self-esteem and positively correlated with appearance comparison and obligatory exercise.     

A receiver operator characteristics analysis of treatment outcome in binge eating disorder to identify patterns of rapid response

The purpose of this study was to perform a receiver operator characteristics (ROC) analysis on a treatment sample from a randomized controlled treatment trial of participants with binge eating disorder (BED). An ROC analysis was completed with 179 adults in a 20-week treatment trial for BED to predict abstinence from binge eating at end of treatment. Percent reductions in binge eating episodes were examined following weeks 1 through 10 of treatment. The rate of percent decrease in binge eating episodes during treatment for BED was a significant predictor of clinical outcome at end of treatment. Participants who demonstrated a 15% reduction in binge eating episodes at week one were more likely to respond positively to treatment and achieve clinical remission. Findings from the current study suggest that a significant reduction in binge eating during the first week of treatment may be predictive of end of treatment remission in those with BED.     

Personality prototypes in individuals with compulsive buying based on the Big Five Model

Personality prototypes based on the Big Five factor model were investigated in a treatment-seeking sample of 68 individuals with compulsive buying (CB). Cluster analysis of the NEO Five-Factor Inventory (NEO-FFI) scales yielded two distinct personality clusters. Participants in cluster II scored significantly higher than those in cluster I on neuroticism and lower on the other four personality traits. Subjects in cluster II showed higher severity of CB, lower degree of control over CB symptoms, and were more anxious, interpersonally sensitive and impulsive. Furthermore, cluster II was characterized by higher rates of comorbid anxiety disorders, and cluster B personality disorders. The two personality prototypes did not differ with respect to obsessive-compulsive features. Finally and of considerable clinical significance, participants in cluster II reported lower remission rates after undergoing cognitive-behavioral therapy. Implications of the results for treatment are discussed.     

Why best cannot last: Cultural differences in predicting regression toward the mean

Four studies were conducted to investigate cultural differences in predicting and understanding regression toward the mean. We demonstrated, with tasks in such domains as athletic competition, health and weather, that Chinese are more likely than Canadians to make predictions that are consistent with regression toward the mean. In addition, Chinese are more likely than Canadians to choose a regression‐consistent explanation to account for regression toward the mean. The findings are consistent with cultural differences in lay theories about how people, objects and events develop over time.
