Contact-promoting behavior, social development, and relationship with parents in sibling juvenile degus (Octodon degus).

This study describes infant socialization in captive parent-young units of the caviomorph rodent Octodon degus. Types of parent-young contact (huddling or squatting) and social interaction (body nosing and accompanying behaviors) are described and their ontogenetic trends examined between postnatal Days 1 and 46. Fathers spent less time than mothers in contact with the young. Mother-young contact decreased postnatally, whereas the amounts of mother-young and father-young social interaction, measured in terms of body-nosing exchanges, showed a continuous increase postnatally; sibling interactions also showed a continuous increase. Father-young interactions tended to be dominated by the father. Young reared with the father cohabiting huddled less with their mother, and engaged in less body-nosing, than young reared in the father's absence. Observations suggested that paternal control of the young may curb juvenile interactions. Young observed without their parents in an unfamiliar enclosure did not groom or "play" as in their home cage with parents present, but engaged in relatively more vocalizing, neck-nosing and forepaw-clasping.

The Pupil Evaluation Inventory. A sociometric technique for assessing children's social behavior.

The Pupil Evaluation Inventory was developed to assess peer ratings of the behavior of male and female children in grades one through nine. Three homogeneous and stable factors emerged from a factor analyss: Aggression, Withdrawal and Likeability. High interrater agreement between male and female raters, stability of factorial structure, high internal consistency, and moderate concurrent validity were found across sex and grade levels. Test-retest reliability was high for a separate sample of third and sixth graders. There was a tendency for higher internal consistency and teacher-peer correlations for the Aggression factor.

The social behavior of myxobacteria.

Myxobacteria are social microorganisms that undergo a spectacular cell cycle. Under starvation conditions, cells aggregate to certain points originating macroscopic fruiting bodies, inside which cells differentiate into myxospores. To accomplish this developmental cycle, cells must communicate. The signals that cells exchange during development as well as the signal transduction systems used by myxobacteria have been intensively studied during the last years. A family of eukaryotic-like protein serine/threonine kinases has been identified in Myxococcus xanthus, indicating that signal transduction systems similar to those used by eukaryotic cells may also function in myxobacteria.

Role-taking ability and social behavior in deaf school children.

This study assessed the relationship between role-taking skill and social-emotional adjustment in deaf children. Twenty-three prelingually deafened boys and girls between 7 and 14 years of age were administered a role-taking task, surreptitious behavioral measures of helping and altruism, and a measure of nonverbal intelligence. In addition, two professionals experienced in working with deaf children rated the social and emotional adjustment, language/communication skills and role-taking ability of the participants. Performance on the role-taking task correlated positively with ratings of emotional adjustment, self-image, communicative effectiveness and role-taking skill. Role-taking performance, however, was not reliably related to any of the measures of social behavior. The study also considered several factors which may account for the apparent independence of role-taking and social behavior.

[Giessen test of the aging dynamics of social behavior].

The Giessen-test was applied during gerontological complex investigations to study the biological ages of predominantly professionally engaged Leipzig citizens. Four dimensions of this psycho-diagnostical procedure showed a clear age-characteristic confirming the tendencially known features of psycho-social ageing. The achieved results point again to the fact that the deficit-model of ageing processes is not justified in psycho-social relations, in particular. The experiences of this experimental series claim further that the Giessen Test should be applied with old-age people reserve only because of the methodical problems implied.

[Social structure and social behavior of elderly ambulatory surgical patients].

Geriatric surgery is getting more and more important. Rising expectation of life, improved pre- and postoperative therapy deferred the age limit for elective operations for about 20 years above the former average. In a chance control we examined the social structure and the social behaviour of older ambulant patients suffering from surgical complaints. The arrangement of those patients according to their age, their homing conditions, their working time after their age limit and the general possibilities of communication were analysed. The importance of the social anamnesis for the therapeutic effect was proved. The regular increase of appropriate dwellings for older persons has to be secured. The possibilities contacts between old-age pensioners and social organisations have to be developed furthermore in order to integrate more and more older persons into social life.

Global social skill ratings: measures of social behavior or physical attractiveness?

Calvert reviewed the literature on social skills and physical attractiveness and concluded that many ratings of social skill may be confounded by the physical attractiveness of the target individual, possibly due to a general perception that physical attractiveness and social competence are positively correlated. In order to examine the influence of physical attractiveness on social skill ratings, Ss made global ratings of social skill and attractiveness for a confederate whose appearance and behavior had been altered to appear attractive or unattractive and socially skilled or unskilled in an assertiveness and heterosocial vignette. The results indicated that the same skilled behavior was viewed as more competent when performed by an attractive person compared to an unattractive person. Attractiveness had no influence on ratings of generally incompetent behavior. Thus, it appears that physical attractiveness does not compensate for poor interpersonal skills, but a skilled, attractive individual may be judged to have particularly good skills. Implications for the assessment of social skills are discussed.

Subgroups of autistic children based on social behavior display distinct patterns of brain activity.

Two questions were addressed in the present study: (1) Do autistic and normally developing children exhibit regionally specific differences in electroencephalographic (EEG) activity? (2) Do subgroups of autistic children classified according to Wing and Gould's (1979) system which emphasizes degree of social impairment exhibit distinct patterns of EEG activity? Twenty-eight children with autism (5 to 18 years of age) and two groups of normally developing children (one matched on chronological age and the other on receptive language level) participated. EEG was recorded from left and right frontal, temporal, and parietal regions during an alert baseline condition. Compared to normally developing children, autistic children exhibited reduced EEG power in the frontal and temporal regions, but not in the parietal region. Differences were more prominent in the left than the right hemisphere. Furthermore, subgroups of autistic children based on Wing and Gould's system displayed distinct patterns of brain activity. Compared to autistic children classified as "active-but-odd," "passive" autistic children displayed reduced alpha EEG power in the frontal region.

Effects of opioid receptor blockade on the social behavior of rhesus monkeys living in large family groups.

Rhesus monkeys of 9 weeks, 48 weeks, 100 weeks, 150 weeks of age (young subjects), or mature parous females that were not lactating were given acute single doses of the opioid antagonist naloxone (0.5 mg/kg) and vehicle on different days and observed in their familial social groups. Naloxone increased the occurrence of affiliative behaviours. Young subjects spent more time in contact with their mothers but showed no changes in social grooming. Maternal contact was actively sought through contact vocalizations, decreasing proximity, and, for the youngest infants, increased attempts to suckle. Mature females made more solicitations for grooming and received more grooming from their companions. These results are interpreted in terms of naloxone blocking the positive effect arising from social contact and thus causing subjects to seek further affiliative comfort.

Effects of methaqualone on social behavior in monkeys (Macaca mulatta).

In an established social group of rhesus monkeys (macaca mulatta) consisting of 1 adult male, 6 adult females, 1 adolescent male and 2 infants, 3 subjects were selected to study the effects of intramuscular methaqualone (10 mg/kg) on behavioral changes in the treated animals, as well as the rest of the colony. Three drug trials alternating with saline controls given to the dominant male, a mid-ranking female and the adolescent male. 20 h of observations were made prior to treatment to serve as a baseline, using 40 discrete behaviors. For each drug and saline period, 2 h of continuous observation was directed towards each target animal (total 36 h), and 12-min behavioral samplings were carried out on each untreated subject in the colony (36 h). Dependent upon the sex and social rank of the subject, different behavioral changes occurred during drug treatment, which were consistent from trial to trial. New behaviors were observed, such as active grooming, autofellatio and masturbation in both males, while some previous behaviors disappeared or decreased. The mid-ranking female showed an increase in aggressive behavior. A biphasic action of the drug was also observed in all subjects. During the first 80--100 min, the males were mainly passive or engaged in grooming, but after this primary phase, they started either to masturbate or autofellate. After approximately 2 h, the social status and behavior of the animals returned to predrug levels. During the drug treatment, marked changes occurred in the behavior of other colony members, e.g. when the dominant male's vigilance was lowered, the highest ranking female replaced him in rank. In general, affiliative activities were increased under the influence of methaqualone, manifesting themselves mainly in grooming, hudding or sitting together: phenomena somewhat parallel to those described among humans taking the drug in group settings.
