Mathematics learning disability in girls with Turner syndrome or fragile X syndrome

Two studies were carried out to examine the persistence (Study 1) and characteristics (Study 2) of mathematics learning disability (MLD) in girls with Turner syndrome or fragile X during the primary school years (ages 5-9 years). In Study 1, the rate of MLD for each syndrome group exceeded the rate observed in a grade-matched comparison group, although the likelihood of MLD persisting through the primary school years was comparable for all three groups. In Study 2, formal and informal math skills were compared across the syndrome groups, a normative group, and children from the normative group who had MLD. Few differences were observed between the Turner syndrome and normative groups. Despite having rote counting and number representation skills comparable to those in the normative group, girls with fragile X had difficulty with counting rules (e.g., cardinality, number constancy). However, this difficulty did not distingush them from the MLD group. Overall, counting skills appear to distinguish the Turner syndrome and fragile X groups, suggesting that the specificity of math deficits emerges earlier for fragile X than Turner syndrome.     

Social Acceptability of Hypothetical Married Couples and Their Relationships

The present experiment tested whether the physical attractiveness attributed to members of married couples would vary according to the social acceptability associated with their interconnected leader-follower roles. American college students rated female and male hypothetical stimulus persons who were described as married to each other. As predicted, both partners who were described as being in a traditional relationship with the husband as leader were stereotyped as being highly attractive. Partners in relationships that deviated from this pattern were stereotyped as being less attractive: Those enacting equal leadership roles were intermediate in attractiveness, and those with the wife as leader were least attractive. Gender identity also varied according to the social acceptability of the couple's roles, with the wife and husband in the traditional relationship being stereotyped as most highly sex typed. The personal attributes of self-esteem and social status were not affected by the social acceptability of the couple's relationship. Regardless of sex, these attributes varied according to the strength of the individual's leadership role. As a consequence, the husband's characteristics were either consistently positive or negative for the different leadership conditions; the wife's attributes were inconsistent.     

Self-presentation and belonging on Facebook: How personality influences social media use and motivations

The present study examined the relationship between the Big Five and the use of Facebook to fulfill belonging and self-presentational needs. One hundred and eighty four undergraduates completed a survey assessing personality and Facebook behaviors and motivations. High agreeableness and neuroticism were the best predictors of belongingness-related behaviors and motivations. Extraversion was associated with more frequent use of Facebook to communicate with others. Self-presentational behaviors and motivations were best predicted by low conscientiousness and high neuroticism. Results suggest that conscientious individuals are cautious in their online self-presentation. Neuroticism, agreeableness, and extraversion were positively associated with the tendency to express one’s actual self. Neuroticism was positively associated with the expression of ideal and hidden self-aspects. The motivation to express these self-aspects mediated the relationship between neuroticism and self-disclosure.     

Racial Socialization Experiences and Symptoms of Depression among Black Youth

Ecological barriers like racism and discrimination can weigh heavily on the shifting emotions of adolescents. We investigated the relationship of racial socialization experiences to the depression symptoms of 160 Black adolescents, including lethargy, low self-esteem, cognitive difficulties, social introversion, irritability, guilt, pessimism, sad mood, instrumental helplessness, and overall depression. Cultural pride socialization was inversely related to adolescent reports of lethargy and low self-esteem while alertness to discrimination socialization was positively related to instrumental helplessness and gender differences were found. Multiple regression findings showed that racial socialization experiences add significantly more predictability of depression symptoms over and above gender, neighborhood risk and resources. Recommendations for the family, mental health professionals and for the development of culturally relevant social interventions are provided.     

Leadership roles and the gender stereotype traits

Men generally occupy the role of leader and women the role of follower in marital relationships. This research tested the hypothesis that these implicit leader-follower roles determine the way in which the gender stereotype traits are typically assigned to women and men. In one condition, the man was described as the leader in the marriage, and in another condition, the traditional power relationship was reversed and the woman was described as the leader. Regardless of sex, the leader was perceived as strong in agency and weak in communion; the follower was perceived as strong in communion and weak in agency. A man and woman, who were described as equal leaders, did not differ in the strength of their agentic and communal traits. A relationship approach was used to formulate the connection between leader-follower roles and the gender stereotype traits.     

Sex differences in self-concept and self-esteem of late adolescents: A time-lag analysis

The presence of historical change in the self-concept and self-esteem of male and female late adolescents was studied using a time-lag design. Five cohorts of students enrolled in the same university and course, consecutively from 1973 to 1977 (total N=1,141), gave self-ratings to 16 evaluative items relating to traits traditionally associated with sex differences. Mean score across items was the self-esteem index, and the vector of ratings for item content was the self-concept index. Historical continuity in self-esteem was found. Males and females did not differ in mean self-esteem, within or between cohorts, and cohort differences accounted for less than 2% of the variance. Cross-cohort similarity in within-cohort sex differences in self-concept was found also. These differences were minimal, accounting for small proportions of the variance and involving no more than 5 items in any cohort. Late adolescents from recent historical eras thus rated themselves in ways inconsistent with societal stereotypes, and showed minimal differences in their self-appraisals. Results are discussed in relation to (1) theoretical positions with which they are inconsistent and (2) an emerging interactionist view, which they appear to support.A shortened version of this paper was presented at the annual meeting of the American Association for the Advancement of Science, Houston, January 1978.

Modeling support provision in intimate relationships

Whereas supportive interactions are usually studied from the perspective of recipients alone, the authors used a dyadic design to incorporate the perspectives of both provider and recipient. In 2 daily diary studies, the authors modeled provider reports of support provision in intimate dyads over several weeks. The 1st involved couples experiencing daily stressors (n = 79); the 2nd involved couples experiencing a major professional stressor (n = 196). The authors hypothesized that factors relating to (a) recipients (their requests for support, moods, and stressful events), (b) providers (their moods and stressful events), (c) the relationship (relationship emotions and history of support exchanges), and (d) the stressor (daily vs. major stressors) would each predict daily support provision. Across both studies, characteristics of providers, recipients, and their relationship emerged as key predictors. Implications for theoretical models of dyadic support processes are discussed.
