Examines the ability of six- and eight-year-old children to hide and recover 20 marbles in a large room containing 100 possible sites. Shows that children tend to concentrate activities in sections of the room and are sensitive to clusters of proximal sites. (HOD)

Reports the use of a memory load-interference paradigm and the easy-to-hard paradigm as converging operations to study capacity limitations in five- to six-year-old's reasoning. Concludes that transitive inference ability in children is capacity limited. (HOD)

Examines whether age-related differences would be observed between young children and adults for discrimination of synthesized, five-format consonant-vowel syllables that differed in voicing onset time of the initial consonants. (HOD)

Explores age differences (6 to 22 years of age) in conceptions about the nature of the skills required by verbal and nonverbal (abstract) intelligence tests. (HOD)

Observed a group of 46 children classified at 20 months as either behaviorally inhibited or uninhibited, and 18 children who were classified aa falling at neither extreme at 5.5 years of age, in contexts designed to evaluate behavior in social situations and heart rate, heart variability, and pupillary dilation to cognitive tasks. (HOD)

Contrasts a fixed-rate presentation list with one in which half the items in a single list were presented at a fast rate and half at a slow rate during paired associative learning with 24 children (aged 8 to 22 years) who were diagnosed with having an attention deficit disorder. (HOD)

Examines relations between Matthews Youth Test for Health ratings on hyperactive boys and diverse measures obtained from five sources: direct behavior observations; staff evaluations, nonparticipant observer ratings, peer nominations, and self-reports. (HOD)

Explores links between aggression in elementary school children and their perceptions of self-efficacy as well as their response-outcome expectancies. (HOD)

To explore the developmental course of racial attitudes, a study assesed racial attitudes in Black children aged four- to five-years and six- to seven-years-old, focusing on reasons for age-related changes in children's attitudes as well as the role of parents in the development of children's attitudes. (HOD)

Explores the hypothesis that parenting practices of abusive mothers are characterized by (1) greater use of power-assertive strategies, (2) less flexible behavior with respect to child compliance attempts, (3) more inconsistent use of parenting techniques, and (4) diminished affective quality. (HOD)

Using the Ainsworth Strange Situation Procedure, a study examined the interrelations between dimensions of emotion and social interactive behaviors to explore the regulatory role of each in mother-infant interaction and how these roles may change in the second year. (HOD)

Investigates whether, and under what conditions, mothers of irritable infants, in contrast to mothers of less irritable babies, become less responsive/sensitive over time. (HOD)

Examines whether vocal exchanges between preverbal infants and their mothers show characteristics similar to those found to be typical of conversational exchanges between competent adult speakers. (HOD)

Measures the degree of interdependence in timing between infants' right and left arm movements and between movements of both arms and the onsets of stressed vowels in tape-recorded infant-appropriate speech. (HOD)

Studied the sleep state organization and EEG patterns at term date in 53 preterm infants as an index of the maturity and integrity of neurophysiological organization that may have implications for their later development. (HOD)
