Compares 27 children with early onset diabetes (EOD) with 24 children with late onset diabetes (LOD) and 30 sibling controls in performance on tests of intellectual functioning and school achievement. Results revealed that duration of illness, age of onset, and hypoglycemic convulsions significantly predicted spatial ability. (Author/RWB)

Observed the decision-reaching and leadership behavior of children in same- amd mixed-age triads by coding their verbalizations in arriving at a consensus for their preference ranking of eight pictures. (HOD)

First- and fifth-grade kibbutz and city children (320 in two studies) individually were requested to distribute rewards between themselves and a partner who had produced either more or less than the subject had. Fifth graders were also asked about the level of effort and merit displayed by themselves and their partners. (Author/RH).

Causal interpretations of story characters' helpful behavior were examined in first, fourth, and sixth graders, and in college-age students.

Type B individuals exhibit the relative absence…

Assessed effects of sleep restriction and extension on 9- to 12-year-olds' neurobehavioral functioning.

Examined parental correlates of child attachment in preschool-aged, economically disadvantaged, urban, African-American sample.
