This study examined the effects of aid from mother and older sibling on the problem-solving behaviors of 120 first graders. Children with older sisters showed more advanced problem solving after aid, while those with older brothers did not. Interpretations in terms of family interaction patterns are offered. (JMB)

Interactions were observed as 80 mothers helped their first-grade children on an object-sorting task in the presence and absence of a third-grade sibling. (JMB)

This study investigated the feelings and concerns of 64 elderly persons, as revealed by a projective instrument, in relation to number and sex of siblings. The number and proportion of female siblings were found to have a greater influence than male siblings on the elderly's feelings and concerns. (Author)

Presents a study of the effects of interaction between a child and his mother or an older sibling on the child's object sorting behavior. Other factors studied included sex of sibling and family size. Subjects were 120 first grade children. (BD)

One hundred sixty sibling pairs from two child families were sampled for sibling interaction behaviors as they relate to measures of categorization style. The study provides additional evidence of the importance of a child's siblings to his cognitive development. (Editor/RK)

Subjects were eight first-graders with older siblings, half from 2-child families and half from larger families. The four sex combinations of sibling pairs were equally represented. Half the children were aided on the task by their mother; half were aided by their sibling. Comparisons were made by sex and family size. nAuthor/JH)

This study investigated the effects of an older sibling's aid in an object sorting task on the younger sibling's conceptual style. Children aided by siblings used descriptive style less than children who worked alone; children aided by siblings four years older used inferential style more than children aided by siblings two years older. Children…

The relationship of family variables to locus of control, under the hypothesis that a larger and more cohesive family provides greater reinforcement for the elderly person's actions was investigated. Elderly persons (N=200) aged 60-90 were interviewed at home and given Rotter's I-E scale. In a regression analysis, after removing effects of age and…

Results are interpreted in terms of role theory and sibling rivalry, and have application for school practice. (Author)
