Relative Contributions of the Male and the Female to Sexual Behavior and Reproductive Success in the Japanese Quail (Coturnix japonica).

Two contrasting investigative techniques provided evidence consistent with the interpretation that female quail (Coturnix japonica) regulate male copulatory behavior by the duration of their immobility and through this behavioral mechanism they also control the rate of fertilization of their eggs. In Experiment 1, copulation tests with males and females from different genetic lines showed that the type of female that participated in a copulatory test significantly influenced the latency of the male's grab, mount, and cloacal contact responses and also determined the efficiency of the male's copulatory behavior. These measures of male performance were correlated with female immobility in Experiment 2, which used a more homogeneous population of quail. Furthermore, 2 of these measures (copulatory efficiency and the latency to make cloacal contact) were correlated with fertilization rate.

Insult, aggression, and the southern culture of honor: An "experimental ethnography."

Three experiments examined how norms characteristic of a "culture of honor" manifest themselves in the cognitions, emotions, behaviors, and physiological reactions of southern White males. Participants were University of Michigan students who grew up in the North or South. In 3 experiments, they were insulted by a confederate who bumped into the participant and called him an "asshole." Compared with northerners (who were relatively unaffected by the insult) southerners were more likely to think their masculine reputation was threatened, more upset (as shown by a rise in cortisol levels), more physiologically primed for aggression (as shown by a rise in testosterone levels), more cognitively primed for aggression, and more likely to engage in aggressive and dominant behavior. Findings highlight the insult–aggression cycle in cultures of honor, in which insults diminish a man's reputation and he tries to restore his status by aggressive or violent behavior.

Mental Health of Lesbian, Gay, Bisexual, and Heterosexual Siblings: Effects of Gender, Sexual Orientation, and Family.

Self-identified lesbian, gay male, and bisexual (LGB) individuals were recruited via convenience sampling, and they in turn recruited their siblings (79% heterosexual, 19% LGB). The resulting sample of 533 heterosexual, 558 lesbian or gay male, and 163 bisexual participants was compared on mental health variables and their use of mental health services. Multilevel modeling analyses revealed that sexual orientation predicted suicidal ideation, suicide attempts, self-injurious behavior, use of psychotherapy, and use of psychiatric medications over and above the effects of family adjustment. Sexual orientation was unrelated to current psychological distress, psychiatric hospitalizations, and self-esteem. This is the 1st study to model family effects on the mental health of LGB participants and their siblings. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Early development in males with Fragile X syndrome: a review of the literature

This article reviews the current bibliographic knowledge on early neurobehavioral development and milestones in Fragile X syndrome (FraX), with emphasis on males affected by the condition. Three broad areas of early development were examined: (1) gross and fine motor, (2) speech and language, and (3) social. The result of the current review indicates very limited information on the developmental milestones in all three areas. The scarce literature on motor development shows that in FraX there is an early developmental delay. Research on speech and language demonstrates pervasive deficits in conversational skills and severe developmental delay, with increasing discrepancy between language level and chronological age in young males with FraX. Finally, deficits in social development in FraX include abnormal gaze, approach and avoidance conflict, and high incidence of autistic spectrum disorders.     

Gender differences in personality traits across cultures: Robust and surprising findings.

Secondary analyses of Revised NEO Personality inventory data from 26 cultures (N =23,031) suggest that gender differences are small relative to individual variation within genders; differences are replicated across cultures for both college-age and adult samples, and differences are broadly consistent with gender stereotypes: Women reported themselves to be higher in Neuroticism, Agreeableness, Warmth, and Openness to Feelings, whereas men were higher in Assertiveness and Openness to Ideas. Contrary to predictions from evolutionary theory, the magnitude of gender differences varied across cultures. Contrary to predictions from the social role model, gender differences were most pronounced in European and American cultures in which traditional sex roles are minimized. Possible explanations for this surprising finding are discussed, including the attribution of masculine and feminine behaviors to roles rather than traits in traditional cultures.

Medial preoptic lesions disrupt parental behavior in both male and female California mice (Peromyscus californicus).

California mice (Peromyscus californicus) are monogamous and naturally biparental, making them an ideal species in which to study the neural basis of paternal behavior. A male or female from each male-female pair was given an electrolytic or sham lesion in the medial preoptic area (MPOA), an area known to be critical for the expression of maternal behavior in rats, and retested for parental responsiveness. MPOA-lesioned males and females showed significantly longer latencies to show parental behavior and spent significantly less time near pups, sniffing pups, and licking pups than sham-lesioned mice. However, MPOA lesions did not reduce time spent hovering over pups. The results suggest that the neural mechanisms mediating paternal behavior are similar to those mediating maternal behavior in this species.

Agonistic Onset Marks Emotional Changes and Dispersal Propensity in Wild House Mouse Males (Mus domesticus).

The authors investigated implications of agonistic onset for anxiety and dispersive motivation in maturing wild house mouse males (Mus domesticus). Laboratory-kept fraternal pairs either developed agonistic dominance or stayed amicable during their first 2 months of life, when the authors assessed open-field behavior and dispersal propensity. State anxiety was lower in amicable than agonistic males and higher in subordinate than dominant ones. During subsequent dispersal trials, 1 dominant and 1 amicable male from 2 fraternal pairs were concomitantly introduced into seminatural enclosures containing 3 females. One male invariably became territorial. The defeated males, if previously dominant, dispersed at significantly higher rates than if previously amicable. The authors conclude that agonistic onset during development represents an adaptive behavioral switch from a submissive-philopatric to agonistic-dispersive coping strategy.

"Gender characteristics and adjustment: A longitudinal study": Addendum.

Reports an error in "Gender characteristics and adjustment: A longitudinal study" by Jennifer Aubé and Richard Koestner (Journal of Personality and Social Psychology, 1992[Sep], Vol 63[3], 485-493). The authors would like to acknowledge that the age 41 longitudinal data used in their study were collected by David McClelland, Carol Franz, Joel Weinberger, Richard Koestner, and Joseph Healy. This data collection was supported by a grant from the Seaver Institute. The data are currently being archived at the Henry Murray Research Center of Radcliffe College, Cambridge, Massachusetts. (The following abstract of the original article appeared in record 1993-01033-001.) Used a prospective longitudinal design to investigate the long-term developmental implications of gender-related interests and traits. Archival data were available for Ss in the R. R. Sears et al (1957) study. Men, who at age 12 yrs endorsed interests and undesirable traits more typically associated with women, had poorer social–personal adjustment at ages 31 and 41 yrs. No effects were found for women. Feminine expressive traits at age 31 yrs did not impact on 41-yr-old adjustment for either men or women, whereas masculine instrumental traits were positively related for both. These findings support a multidimensional view of gender and indicate that harsher consequences follow when adolescent boys endorse nontraditional gender-related interests and undesirable traits than when girls do so.

"Rorschach and TAT indices of homosexuality in overt homosexuals, neurotics, and normal males": Erratum.

Reports an error in the original article by Anthony Davids, Mark Joelson, and Charles McArthur (Journal of Abnormal & Social Psychology, 1956[Sept], 53, 161-172). In the section on TAT results, under the heading of Signs suggested for further confirmation (p. 168), it states incorrectly (line 15) that the sign of a strong unresolved attachment to a father or father figure was scored in stories composed for Card 8. The sign was in fact scored in stories composed for TAT Card 7. (The following abstract of this article originally appeared in record 1958-02891-001). Rorschach and TAT protocols of 20 male overt homosexuals, 20 male neurotics, and 20 normal male students were compared in order to determine whether proposed homosexual signs were discriminative. The homosexual group gave a significantly greater mean number of the Rorschach and TAT signs than did either nonhomosexual group. "Within the homosexual group, correlation between the number of Rorschach signs and number of TAT signs produced by each S proved significant, serving as a check on the validity of both schemes and indicating the consistency of these 2 diverse measures of homosexuality."

Comparison of the D 48, Cattell Culture Fair, and Army Beta Tests in a sample of college males.

The D 48 test, the Cattell Culture Fair, and the Revised Beta Examination were administered to lower-division college males (N = 94 to 33). Additional verbal and nonverbal measures, as well as the grade point average (GPA) were also available. None of the 3 tests correlated very highly with the GPA, but of the 3 only the D 48 correlated significantly (.22 significant at the .05 level). Analysis of the results indicates that the D 48 has slightly more predictive validity than the Culture Fair or Army Beta and that it is essentially similar to these tests in its pattern of relationships to other measures of ability.
