The present study was concerned with investigating children's generalized locus of control of reinforcement and its possible relationship to the demographic variables of birth order and family size. The sample consisted of 93 school children in Grades 6, 7, and 8. The analysis of data was by a 2 x 3 factorial design. Results indicated no significant differences in the generalized locus of control orientations of first-born, intermediate-born, and youngest children. Results also indicated that children of these different birth order positions from small families and from large families did not differ significantly in their generalized locus of control orientation. A correlational study of the data showed that the children's locus of control orientations were unrelated to sex differences.

This study investigates (1) whether infants in a day-care setting exhibit sexual preferences in the choice of a playmate, and (2) whether males exhibit more overt acts in play than do females. Eight male and eight female infants, attending a day-care center, paired by age (ages twelve to twenty-four months), were selected as subjects. Each of the sixteen children was observed for a ten-minute period on four separate days, over a two-week period, a total of forty minutes' observation time per child. No significant differences were found between male and female infants involving the preference of the sex of a playmate, or between male and female overt behaviors.

This study investigates (1) whether infants cared for by a single caregiver exhibit more attachment behaviors than do infants cared for by multiple caregivers and (2) whether sex differences are found in these behaviors. Twenty-six Black infants, nine to twenty-three months of age, in a day-care center, were observed during one brief low-stress separation from a caregiver. Data were taken using six indices of attachment: maintaining proximity, visual regard, touching, protesting, seeking proximity, and greeting. Where subjected to a two-way analysis of variance, the obtained results showed no significant differences in the effects of the two types of care. However, visual regard and greeting behaviors were observed significantly more frequently in females than in males.

It is hypothesized in this study that children reared with "concerned" mothers (N) will display significantly superior intellectual performance and less neurological impairment as compared with children reared with neglectful mothers (MN) and children diagnosed as failure to thrive (FTT, falling below the third percentile in height and weight). The FTT children will show significantly more deficits than both N and MN groups. The participants in this study were forty-five children rigidly matched on all possible variables. F-tests and Newman-Keuls' analyses reveal severe intellectual deficits in both MN and FTT groups. The FTT group displayed significantly more neurological deficits lending support for a nutritional basis of this syndrome as opposed to the traditional psychogenic explanation.

The present study evaluated two hypotheses concerning the comparability of scores of the WISC and WISC-R through correlation of obtained scores on both scales. Forty subjects, representing 10 age levels, constituted the experimental sample. Each subject was administered the WISC, followed in 28 days by the WISC-R. Data analysis revealed significant (.05) correlations between scores on comparable WISC and WISC-R subtests except Arithmetic and Coding. The Verbal, Performance, and Full Scale IQ scores correlated .5468, .5773, and .6240 respectively (p < .01). Conclusions were drawn that caution should be taken in comparison and interpretation of scores on the two scales due to several low correlation coefficients obtained as well as numerous changes between the scales. Further study is recommended.
