The influence of an older brother on the physical activity or passivity of younger brothers and sisters was examined through teacher observations of children in kindergarten through sixth grade and through self reports of college students. Study included whites and Mexican Americans. (CW)

Although relationships between siblings potentially have the longest duration of any human relationship, research has not yet established the salient, relevant features of the sibling role in adulthood. An investigation was conducted to identify and examine the influences on the frequency of, and motivation for, contact with adult siblings.…

Scores on a mental development scale were correlated for 8-month-old twins and other sibling pairs. Greater correlations were found between twins than sibling pairs. (ST)

The data indicate that the influence of a brother or sister is considerably greater upon the second born than upon the first born. The magnitude of the sex of sibling effect is probably dependent upon whether a sibling is present during the first few years of life, a period during which many enduring response patterns are being acquired.

This study of 115 foster home placements was conducted to determine the effect of placing siblings in the same foster home. (BRT)

Results for the 30 families as seen as "teaching-demonstration" families suggest that Adler's contention that more "first and youngest" children reveal problems and concerns (as defined by their parents) is correct. (Author)

Studied factors contributing to consensus, or the level of agreement about life, between older adults (N=275) and the sibling with whom they had most contact. Found greater consensus when there were fewer expectations of the sibling, similarity of educational backgrounds, and when the respondent was a male and his sibling was female. (Author/NB)

Tests whether an increase in number of sons in the family decreases the sex-typing of traditionally female tasks and whether an increase in the number of daughters increases sex-typing of traditionally female chores. Examines the reverse pattern for male chores. Results support the hypotheses for the female-specific tasks. (BH)

The case study traces the early education of an exceptionally intellectually talented sister and brother identified by the Study of Mathematically Precocious Youth (SMPY) at the Johns Hopkins University. The experience of the parents with education, both their own and their children's are examined. (Author/CL)

Investigates three hypotheses derived from previous research, that different ordinal position groups manifest differential personal preference patterns, as measured by the Kuder Preference Record. (Author)

Identifies three styles of sibling rivalry and three parent leadership styles, discussing parental mediation of sibling disputes through contracting and providing examples of group discipline techniques that facilitate development of less negative forms of rivalry and that support positive sibling bonding.

Using National Longitudinal Survey of Youth data (n=8,400) to replicate an earlier study, research revealed that sibling sex composition had no effect on educational attainment of whites. Blacks who had one or more sisters had higher attainment than those who had none. (SK)
