Piaget's concept of "internalization" is analyzed and related to Bruner's representational theories of cognitive development. Cognitive structures are shown to be real exclusively in an actual representation. (Author/SDH)

Describes procedures for identifying stimuli in the natural environment whose presence was associated with altered probabilities for both the initiation and persistence of noxious responses. (Author/SDH)

Nineteen socially isolated preschool children were exposed either to four videotapes in which social skills were modeled (treatment) or to four sequences of a nature film (control). Observations indicated that treatment produced increases in the frequency with which subjects dispensed and received social reinforcement and the frequency of social…

Investigated the degree to which an individual disregards information about himself and his environment, as a function of his locus of control patterns, and hence is less responsive to or influenced by a given segment of information. Subjects were 341 fourth- and fifth-grade children. (SDH)

A study of the relationship between pain-relieving drugs given to mothers during labor and delivery and neonatal behavior as assessed by the Brazelton Scales. Tested 44 infants on eight different days during their first month of life. (SDH)

Presents a description of a neonatal monitoring system and the studies used in its validation. (SDH)

Thirty-one normal neonates were monitored for 24 hours on a newly developed movement monitor which provided measures of noncrying activity and counts of various movement amplitudes. (Author/SDH)

A study of recorded and analyzed inspection times in a picture recognition memory task involving three different delays between inspection and test. Subjects were 108 4-, 6-, and 8-year-old children. (Author/SDH)

This study attempts to follow the development of an "awareness" of the importance of consistency in a logical system with three elements and one operation. Subjects were 127 male and female students, 9-, 11-, 14-, and 16-years-old. (Author/SDH)

A set of tasks theoretically presumed to require equivalent logical competence (multiplication of classes, multiplication of relations, seriation, and transitivity) was administered to 64 first and second graders. Response measures emphasizing the operative and figurative aspects were compared within each task. (Author/SDH)

An evaluation of selective generalization of habituation on the basis of meaningful categories of stimuli. Also explored are the sex differences in conceptual generalization of habituation. Subjects were 36 toddlers with a mean age of 40 months. (SDH)
