Self-esteem and memory

This article describes two potential bases for memory bias associated with global self-esteem. According to the mood-congruence model, activation of either dimension of self-esteem (self-competence or self-liking) produces an affective state that facilitates retrieval of traces that are consistent with that state while hindering retrieval of traces that are inconsistent. According to the relevance model, activation of either dimension results in superior encoding of matching negative content by individuals who are low on the dimension. Three studies were conducted to determine which model best accounts for the pattern of bias across distinct content categories. Results were generally consistent with the relevance model.     

Unwanted and unfollowed: Defining ghosting and the role of social media unfollowing

Ghosting involves terminating communication, including through technological mediums, as a means of ending a relationship. Despite attention from popular media, empirical examinations of this breakup strategy are sparse. Using a correlational design, we examined the defining features of ghosting including its associations with other breakup tactics, whether it is an exclusively unilateral strategy, and the role of social media unfollowing in its implementation. A convenience sample of primarily undergraduate students (n = 260) completed an online survey describing recent breakups, indicating the disengagement tactics used, social media unfollowing, and the extent to which the breakups involved ghosting. Findings indicated that ghosting is extremely common, it was used to terminate more than half of participants' recent relationships. Most participants had experienced a breakup involving ghosting as either the disengager and/or the recipient. Ghosting was found to involve less open confrontation, more avoidance/withdrawal and de-escalation tactics. Contrary to previous research, ghosting can occur bilaterally, with partners ghosting each other. Social media unfollowing is an important aspect of ghosting. Relationships ended via ghosting have fewer post-breakup connections than those ended through other strategies. Typically, ghosters initiate social media unfollowing. Findings provide insight into how ghosting should be conceptualized and measured in future explorations.     

Genetic Knowledge Among Participants in the Coriell Personalized Medicine Collaborative

Genetic literacy is essential for the effective integration of genomic information into healthcare; yet few recent studies have been conducted to assess the current state of this knowledge base. Participants in the Coriell Personalized Medicine Collaborative (CPMC), a prospective study assessing the impact of personalized genetic risk reports for complex diseases and drug response on behavior and health outcomes, completed genetic knowledge questionnaires and other surveys through an online portal. To assess the association between genetic knowledge and genetic education background, multivariate linear regression was performed. 4 062 participants completed a genetic knowledge and genetic education background questionnaire. Most were older (mean age: 50), Caucasian (90 %), female (59 %), highly educated (69 % bachelor’s or higher), with annual household income over $100 000 (49 %). Mean percent correct was 76 %. Controlling for demographics revealed that health care providers, participants previously exposed to genetics, and participants with ‘better than most’ self-rated knowledge were significantly more likely to have a higher knowledge score (p?<?0.001). Overall, genetic knowledge was high with previous genetic education experience predictive of higher genetic knowledge score. Education is likely to improve genetic literacy, an important component to expanded use of genomics in personalized medicine.     

Token-mediated tool-use by a tufted capuchin monkey (Cebus apella)

This research examined token-mediated tool-use in a tufted capuchin monkey (Cebus apella). We conducted five experiments. In experiment 1 we examined the use of plastic color-coded chips to request food, and in experiments 2–5 we examined the use of color-coded chips to request tools. Our subject learned to use chips to request tools following the same general pattern seen in great apes performing analogous tasks, that is, initial discrimination followed by an understanding of the relationship among tokens, tools, and their functions. Our findings are consistent with the view that parallel representational processes underlie the tool-related behavior of capuchins and great apes.

Psychometric properties of the children's atypical development scale

The Children's Atypical Development Scale (CADS) is a 53-item rating scale designed to measure unusual behaviors in children. Principal-factor analysis on a clinic-referred and pediatric sample of 474 children resulted in a four-factor solution: Communication Deficits, Lability, Social Relatedness Deficits, and Preoccupation. The CADS is internally consistent and has adequate temporal stability. CADS factor scores were differentially associated with parent and teacher rating scales, IQ, and Continuous Performance Test errors. The scale shows promise as a clinical and research tool for assessing atypical behaviors associated with pervasive developmental disorder and other neurobehavioral disorders.This research was supported in part by a grant from the Smart Family Foundation. The authors are grateful to James P. O'Donnell, Catherine Lord, and Frank A. Zelko for their comments on an earlier draft.     

Recruitment modeling applied to longitudinal studies of group differences in intelligence

In longitudinal studies data is collected in a series of waves. Each wave after the first suffers from attrition. Therefore it can be difficult to discriminate between changes in sample parameters due to a longitudinal process (e.g. ageing) and changes due to attrition. The problem is particularly vexing if one of the purposes is to compare differences between two or more groups over time, because there may be differential attrition across groups. We refer to this as a recruitment problem, because the sample studied in any wave after the first can be thought of as having been recruited from a preceding wave. We present a mathematical model of the recruitment process. We then apply it to two large longitudinal studies, the British Cohort Survey 1970 and the National Child Development Study (1958), to demonstrate how we can identify effects expected from recruitment alone. As an illustration we show that differential recruitment would predict increasing differences between estimates of men's and women's intelligence as the studied sample ages.     

Patient–Provider Communication About Sexual Health: The Relationship with Gender, Age, Gender-Stereotypical Beliefs, and Perceptions of Communication Inappropriateness

This investigation examined patient–provider communication about sexual health related to gender and age. Data were collected from 277 individuals, aged 18–60, via convenience and snowball sampling at a large university in southwestern United States. Results indicate women are more proactive about their sexual health than men and tested for STDs more frequently. Women, more than men, initiate discussions with their healthcare provider about sexual health matters and healthcare providers are more likely to initiate communication about such matters with women than men. Men hold stronger gender-stereotypical beliefs than women, are less likely to initiate conversations about sexual issues with their provider, and believe sexual discussions with their partner are inappropriate. Age relates to sexual activity initiation and perceived STD risk.     

Exploring Predictors of Outcome in the Psychosis Prodrome: Implications for Early Identification and Intervention

Functional disability is a key component of many psychiatric illnesses, particularly schizophrenia. Impairments in social and role functioning are linked to cognitive deficits, a core feature of psychosis. Retrospective analyses demonstrate that substantial functional decline precedes the onset of psychosis. Recent investigations reveal that individuals at clinical-high-risk (CHR) for psychosis show impairments in social relationships, work/school functioning and daily living skills. CHR youth also demonstrate a pattern of impairment across a range of cognitive domains, including social cognition, which is qualitatively similar to that of individuals with schizophrenia. While many studies have sought to elucidate predictors of clinical deterioration, specifically the development of schizophrenia, in such CHR samples, few have investigated factors relevant to psychosocial outcome. This review integrates recent findings regarding cognitive and social-cognitive predictors of outcome in CHR individuals, and proposes potential directions for future research that will contribute to targeted interventions and improved outcome for at-risk youth.
