Pheromonally induced sexual maturation in females: regulation by the social environment of the male.

Social subordination, which suppresses gonadal function in juvenile and adult male house mice, also suppresses the activity of an androgen-dependent urinary pheromone that accelerates the rate of sexual maturation in juvenile females. Pheromone production may also be suppressed by the presence of pregnant or lactating females. This suggests that the social environment may influence the fertility of population females by altering urinary pheromone activity in the male.

Effects of modification of the social environment on young monkey development.

Experiments and observations of the effects of modifications of the social environment on the young primate's relationship with its mother and its social-sexual development have begun to delineate the large number of variables that determine and affect the attachment relationship and that are contingent upon it. Attachment can occur to a number of mother substitutes, including a dog. Early experience has special importance but young monkeys are surprisingly responsive and adaptable to substitute maternal stimuli. The quality of developing social behavior is dependent on both the quantity and quality of an attachment. We have yet to learn what are the critical component stimuli which make up an adequate early social environment for young monkeys and apes.

A typology of family social environments.

A sample of 100 families measured on ten dimensions of their social environments was subjected to cluster analysis to develop an empirically based taxonomy of families. Six distinctive clusters of families were indentified: Expression-Oriented, Structure-Oriented, Independence-Oriented, Achievement-Oriented, Moral/Religious-Oriented and Conflict-Oriented. The clusters showed systematic differences in background characteristics such as size, ethnic minority composition, drinking patterns, and family disturbance and incongruence. Some evidence that certain clusters of families are composed of different sub-clusters was presented. An empirically derived taxonomy of the social environments of families may help to understand how different family environments are linked to different family outcomes.

Achievement

Plasma steroid tendency, social environment and Eimeria necatrix infection.

Chickens from a line selected for high levels of plasma corticosterone when housed in an environment faciliating considerable social interaction were more resistant to Eimeria necatrix infection than those from a line selected for low levels of plasma corticosterone housed in an environment that minimized social interaction. Individuals in the high steroid group had a more active phagocytic defense and fewer schizonts than those in the low steroid group.

[Social environment of the puerpera and her attitude towards the child].

The mother's attitude towards the newborn child is influenced considerably as well by the number of children, the respective mother is responsible for, as by other factors of her social environment, by the partners attitude towards mother and child, by the efforts in respect of a conscious planning of the human reproduction. Small birth orders, favourable conditions regarding family and social environment, but nevertheless conscious family planning are in high correlation with a positive attitude of the young mother towards the newborn child.

Adult

Biographical situation of scoliotic children and their relationship to the social environment(author's transl).

Studies were conducted to determine whenther or not scoliosis in childhood affects the behavior and experience of the affected children. Two groups of scoliotic and nonscoliotic children were examined with selected psychological tests. No differences could be found in regard to neuroticism, extraversion, manifest fear or the children's self-image. Differences were found in regard to the social environment which scoliotic children experienced as more demanding and supportive. As a result they were more concerned with achievement in a performance situation and more confident of success. The type and extent of the psychological effects of scoliosis is determined by the position accorded to the children by the social environment. Negative consequences can best be dealt with by educating the parents.

Adolescent

Behavioral and neurological comparisons of neonates born to mothers of differing social environments.

Sixty newborn infants, 30 born to parents of middle to upper-middle socioeconomic status and 30 born to parents of limited personal-social resources, were assessed on the Neonatal Behavioral Assessment Scale. Although no difference between groups was found in motor and neurological status, data from this study did indicate that the prenatal factors, having no obvious physiological base, associated with the parental social environment, may affect the newborn's behavioral outcome.

Child Behavior

Plasma concentrations of testosterone in the developing ram in different social environments.

Plasma testosterone profiles were determined by taking frequent blood samples at intervals from birth to 21 months of age from rams reared in isolation, in an all-male group and in a mixed-sex group. The testosterone pattern was not modified by these different social environments. The ability of the ram to copulate when first exposed to an oestrous ewe, apparently a maturational process, was also independent of social rearing. At birth plasma testosterone levels were detectable but low, they were higher at 10 and 16 weeks of age and showed a marked rise by 26 weeks, coincident with the time of puberty. Depressive effects of season on testosterone profiles occurred during the 2nd year of life but not the 1st year.

Age Factors

Salience of ethnicity in the spontaneous self-concept as a function of one's ethnic distinctiveness in the social environment.

How likely people are to think of themselves in terms of a given personal characteristic is predicted from the distinctiveness postulate that the person, when confronted by a complex stimulus (such as the self), selectively notices and encodes the stimulus in terms of what is most peculiar about it, since these peculiar characteristics are the most informative in distinguishing it from other stimuli. This partial view of the person as an information-encoding machine (one is conscious of oneself insofar as, and in the ways that, one is different) is used to derive four predictions implying that ethnic identity is salient in children's spontaneous self-concepts to the extent that their ethnic group is in the minority in their social milieu at school. Our measure of salience of ethnicity was its being spontaneously mentioned by the children in response to a nondirective "Tell us about yourself" question. All four predictions were confirmed, though for several of the findings there are plausible alternative explanations.

Adolescent

Social support and the social environment of depressed and normal women.

A brief self-report measure of social support was administered initially to a student population, and then to a sample of hospitalized depressed women. Comparison of the responses of the 32 patients with 35 student women of similar age showed no differences between the groups in number of cohabitants or of casual friends, or in faith in the value of talking over one's problems. Patients were more likely than controls to report having no or few confidants, nobody confiding in them, and little confidence in being liked by others. Training in social skills specific to fostering intimacy is suggested as a therapeutic step, and modifications to the social support measure for future use discussed.
