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.

Autistic adolescents need direct, systematic training of social skills since major difficulties in communication, lack of empathy, and various changes during adolescence present major roadblocks to the acquisition of normal peer relationships and increasing independence. A case study approach was utilized to examine treatment effects of a social skills training program implemented with four autistic adolescent boys in a naturalistic setting. Findings based on objective measures and subjective reports indicated that each subject made gains in targeted social skills over the course of treatment. Treatment strategies such as modeling, coaching, roleplaying, one to one instruction, and in vivo procedures were found to be effective teaching techniques. Major benefits and limitations of the study were discussed.
