Perceptions of Younger Single Adults as a Function of Their Gender and Number of Children

ABSTRACT. Research suggests that children may interfere with single parents’ romantic experiences. Although both male and female single parents face these challenges, they have stronger associations with the romantic satisfaction of single mothers as compared to single fathers. The two current studies examined aspects of attractiveness and dating across various dimensions for both younger single women and men, with and without children. Results of Study 1 indicated interactive effects of target gender and parental status on perceptions of both attractiveness and dating potential. Results of Study 2 indicated differential ratings on multiple dimensions (i.e., attractiveness, stress, motivation for dating, and positive qualities) of younger single adults on the basis of gender, parental status, and the number of children single parents were reported as having. Implications for importance of social support and difficulty of repartnering are discussed.

Reading between the minds: the use of stereotypes in empathic accuracy

An ideal empathizer may attend to another person's behavior in order to understand that person, but it is also possible that accurately understanding other people involves top-down strategies. We hypothesized that perceivers draw on stereotypes to infer other people's thoughts and that stereotype use increases perceivers' accuracy. In this study, perceivers (N = 161) inferred the thoughts of multiple targets. Inferences consistent with stereotypes for the targets' group (new mothers) more accurately captured targets' thoughts, particularly when actual thought content was also stereotypic. We also decomposed variance in empathic accuracy into thought, target, and perceiver variance. Although past research has frequently focused on variance between perceivers or targets (which assumes individual differences in the ability to understand other people or be understood, respectively), the current study showed that the most substantial variance was found within targets because of differences among thoughts.     

An Analysis of Expressions Used by Adolescents at Varying Economic Levels to Describe Accepted and Rejected Peers

Conservation has been found to be positively and moderately correlated with reading readiness, and only slightly less correlated with reading readiness than intelligence as measured by the Primary Mental Abilities Test. A moderate correlation also existed between conservation and intelligence. It was suggested that conservation would be worthy of attention by primary teachers as a predictor of the child's readiness for learning to read.     

The effects of acute 17beta-estradiol treatment on gene expression in the young female mouse hippocampus

Previous studies have demonstrated that treatment with 17beta-estradiol (E(2)) improves both spatial and nonspatial memory in young female mice. Still unclear, however, are the molecular mechanisms underlying the beneficial effects of E(2) on memory. We have previously demonstrated that a single post-training intraperitoneal (i.p.) injection of 0.2 mg/kg E(2) can enhance hippocampal-dependent spatial and object memory consolidation (e.g., Gresack & Frick, 2006b). Therefore, in the present study, we performed a microarray analysis on the dorsal hippocampi of 4-month-old female mice injected i.p. with vehicle or 0.2 mg/kg E(2). Genes were considered differentially expressed following E(2) treatment if they showed a greater than 2-fold change in RNA expression levels compared to controls. Overall, out of a total of approximately 25,000 genes represented on the array, 204 genes showed altered mRNA expression levels upon E(2) treatment, with 111 up-regulated and 93 down-regulated. Of these, 17 of the up-regulated and 6 of the down-regulated genes are known to be involved in learning and memory. mRNA expression changes in 5 of the genes were confirmed by real-time quantitative PCR analysis, and protein changes in these same genes were confirmed by Western blot analysis: Hsp70, a heat shock protein known to be estrogen responsive; Igfbp2, an IGF-I binding protein; Actn4, an actin binding protein involved in protein trafficking; Tubb2a, the major component of microtubules; and Snap25, a synaptosome-specific protein required for neurotransmitter release. The types of genes altered indicate that E(2) may induce changes in the structural mechanics of cells within the dorsal hippocampus that could be conducive to promoting memory consolidation.     

Mother and father adjustment during early parenthood: the roles of infant temperament and coparenting relationship quality

We explored how parent gender, infant temperament, and coparenting dynamics worked together to shape mothers’ and fathers’ depressive symptoms, stress, and parental efficacy during early parenthood. We were interested in the coparenting relationship as a context that shapes how parents respond to their infant's temperamental qualities. Participants were 139 couples who had recently given birth to their first child. Parent reports of temperament were collected when the infant was 4–8 months old and reports of coparenting and parent adjustment were collected at 13 months. Two-level random intercept models revealed interactions between temperament and coparenting, highlighting the family system as a context for how men and women adapt to their parenting role. There was little evidence for mother–father differences in these associations.     

Sources of avoidance motivation: Valence effects from physical effort and mental rotation

When reaching goals, organisms must simultaneously meet the overarching goal of conserving energy. According to the law of least effort, organisms will select the means associated with the least effort. The mechanisms underlying this bias remain unknown. One hypothesis is that organisms come to avoid situations associated with unnecessary effort by generating a negative valence toward the stimuli associated with such situations. Accordingly, merely using a dysfunctional, ‘slow’ computer mouse causes participants to dislike ambient neutral images (Study 1). In Study 2, nonsense shapes were liked less when associated with effortful processing (135° of mental rotation) versus easier processing (45° of rotation). Complementing ‘fluency’ effects found in perceptuo-semantic research, valence emerged from action-related processing in a principled fashion. The findings imply that negative valence associations may underlie avoidance motivations, and have practical implications for educational/workplace contexts in which effort and positive affect are conducive to success.     

Achievement of Children in Orphan Homes as Revealed by the Stanford Achievement Test

Regression surface analysis was used to examine relationships between teacher perceptions of school related behavior and children's academic achievement at different levels of intelligence, social status, and family environment. Data were collected as part of a national survey of 11-, 12-, and 15-year-old English schoolchildren (N = approximately 3000). The regression surfaces were constructed from models which examined possible linear, curvilinear, and interaction relations between the variables. In the analysis the Jackknife technique was used to adjust the significance levels. Two propositions are suggested by the results that (a) at each level of intelligence and social environment, changes in the teacher perceptions of student behavior are associated with modest changes in academic achievement, and (b) at each level of teacher perceptions, increases in intelligence and social environment scores are related to sizable increments in academic achievement.
