Fathers' participation in the care of their preschool children

Correlates of fathers' participation in the care of their preschool children were investigated, using two indices of participation: (a) child-care tasks performed by the father independently; and (b) child-care tasks performed jointly with the mother. Subjects were 79 fathers and mothers of Caucasian middle-class 4-year-old girls and the girls themselves, and 36 fathers and mothers of a matched sample of preschool boys. Major factors examined as possible influences on participation included (a) maternal work-role pattern; (b) fathers' and mothers' sex-role ideology; and (c) family work load, i.e., family size and number of children under 6. Indices of variables conceptualized as possible consequences of participation included (a) girls' sex-role stereotyping; (b) fathers' self-perceptions of masculinity and femininity; and (c) wives' role-pattern satisfaction. Results indicated that fathers' independent (but not joint) performance of child-care tasks was significantly and positively related to maternal work-role variables and to nontraditional sex-role ideology of fathers and wives, but not to family work load. Independent (but not joint) participation was significantly and negatively related to daughters' stereotyping and to fathers' perceptions of themselves as stereotypically masculine. Wives' role-pattern satisfaction was unexpectedly found to be negatively related to both joint and independent participation.Data reported here were gathered as part of a research project supported by NIMH Grant #25215.

Gustatory,salivary, and oral thermal responses to solutions of sodium chloride at four temperatures

Using eight highly trained Ss, sensitivity to near threshold levels of NaCl was significantly greater at solution temperatures of 22° and 37°C than at 0° or 55°C. Perceived intensity increased linearly with concentration (0.04%–0.64% NaCl) at all four solution temperatures, with the two lower considered slightly more intense than the two higher temperatures. Biomodal distributions were obtained for hedonic judgments at all temperatures, with three Ss showing greater liking and five Ss showing greater disliking of increasing concentrations. Parotid salivary flow was inversely related to the taste sensitivity, i.e., significantly lower flow rates were obtained for the intermediate than for the hot or cold solutions, independent of salt content. When solution temperature was O°C, the minimum temperature of the oral cavity was 9°–20°C; when solution temperature was 55°C, the maximum temperature of the oral cavity was46°–49°C.     

Intelligence and semen quality are positively correlated

Human cognitive abilities inter-correlate to form a positive matrix, from which a large first factor, called ‘Spearman's g’ or general intelligence, can be extracted. General intelligence itself is correlated with many important health outcomes including cardio-vascular function and longevity. However, the important evolutionary question of whether intelligence is a fitness-related trait has not been tested directly, let alone answered. If the correlations among cognitive abilities are part of a larger matrix of positive associations among fitness-related traits, then intelligence ought to correlate with seemingly unrelated traits that affect fitness—such as semen quality. We found significant positive correlations between intelligence and 3 key indices of semen quality: log sperm concentration (r = .15, p = .002), log sperm count (r = .19, p < .001), and sperm motility (r = .14, p = .002) in a large sample of US Army Veterans. None was mediated by age, body mass index, days of sexual abstinence, service in Vietnam, or use of alcohol, tobacco, marijuana, or hard drugs. These results suggest that a phenotype-wide fitness factor may contribute to the association between intelligence and health. Clarifying whether a fitness factor exists is important theoretically for understanding the genomic architecture of fitness-related traits, and practically for understanding patterns of human physical and psychological health.

The two faces of dominance: The differential effect of ingroup superiority and outgroup inferiority on dominant-group identity and group esteem

The present paper provides evidence that dominant-group members distinguish dominance framed as ingroup superiority from dominance framed as outgroup inferiority, and that ingroup superiority enhances esteem for, and thus identification with, the group more than outgroup inferiority. In Experiment 1, Democrats report higher levels of party identification after being told that Democrats won an election than after being told that Republicans lost the election. These effects are attenuated among dominant group members whose values are in conflict with how dominance was achieved. In Experiments 2a and 2b, unearned dominance framed as ingroup superiority resulted in higher levels of White identification than unearned dominance framed as outgroup inferiority among Whites who did not value meritocracy. In contrast, Whites who valued meritocracy did not increase their levels of identification with the group. In Experiment 2b, this interactive effect on racial identification was mediated by esteem for the group.     

Does harboring hostility hurt? Associations between hostility and pulmonary function in the Coronary Artery Risk Development in (Young) Adults (CARDIA) study.

OBJECTIVE: To examine the cross-sectional association between hostility and pulmonary function (PF) and its consistency across race/ethnicity-gender groups. DESIGN: Data were from the Coronary Artery Risk Development in (Young) Adults (CARDIA) cohort study (N=4,629). Participants were recruited from 4 metropolitan areas in the United States, ages 18-30 years at baseline in 1985-1986, approximately balanced across race/ethnicity (Black, White) and gender. MAIN OUTCOME MEASURES: Main outcome measures were percent predicted values for forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC). RESULTS: In full-sample multiple linear regression analyses, each 1 standard deviation (SD) increase in hostility was associated with a 0.66% decrease in FEV-sub-1 (p=.0002) and a 0.60% decrease in FVC (p=.0006). This inverse association of hostility with PF remained after controlling for age, height, current socioeconomic status (SES), participant smoking status, and asthma and is more consistent than that of smoking and PF. In stratified analyses, each 1 SD increase in hostility predicted statistically significant reductions in PF for Black women, White women, and Black men. For White men, hostility showed no statistically significant relation with PF, although the pattern relating hostility to PF was similar to the pattern in the other three groups. Further, both of the post hoc three-way interaction terms for hostility, race/ethnicity, and gender predicting FEV-sub-1 and FVC were nonsignificant. CONCLUSION: PF was inversely associated with hostility across race/ethnicity and gender, independent of age, height, current SES, smoking, and asthma. On the basis of these cross-sectional findings, the authors hypothesize that higher hostility will predict a more rapid decline in PF.     

A Preliminary Study Investigating the Effectiveness of the Caring for Body and Mind in Pregnancy (CBMP) in Reducing Perinatal Depression,Anxiety and Stress

Prenatal mental illness is a significant public health issue with intergenerational consequences. Caring for Body and Mind in Pregnancy (CBMP) is an Australian, 8-week mindful parenting program. The primary aim of this study was to investigate the effectiveness of CBMP in reducing pregnant women’s levels of depression, anxiety, perinatal depression, perinatal anxiety and stress. The sample consisted of 109 pregnant women at-risk for perinatal depression and anxiety. The mean age of the sample was 33.52 years (SD?=?4.90), ranging from 21 to 45 years. A within group, pre-post research design was used to examine whether CBMP improves participants’ scores on outcome measures. Wilcoxon Signed Rank test results indicated that CBMP significantly reduced depression, anxiety, perinatal depression, perinatal anxiety and general stress scores, while significantly increasing self-compassion and mindfulness with moderate to strong effect sizes. The double mediation hypothesis was supported with self-compassion t (71)?=??2.23, p?<?03, b2?=??1.96, SE?=?88, 95% CI?=??3.71, ?.20, having a stronger influence in reducing perinatal depression than mindfulness t (71)?=??2.68, p?<?.01, b3?=??.07, SE?=?.03, 95% CI?=??.13, ?.02. Further research, using a randomized controlled design with appropriate control conditions, is needed to establish the effectiveness of CBMP in reducing psychological distress amongst pregnant women at risk of developing depression, anxiety or stress.
