Infants were classified as high or low in differential vocal responsiveness (DVR), and tested for degree of response to stimulation by a stranger and to stimulation by their mothers. The infants' DVR classification was related to scores on the Stanford-Binet and the Illinois Test of Psycholinguistic Abilities. (Author/SS)

Investigates the magnitude of the over- and under-estimated portions of the Ebbinghaus (Titchner's circles) illusion in 688 subjects ranging in age from 5 to 70 years. (Author/SS)

Suggests an alternate, and optimistic, interpretation of developmental data that has been interpreted as indicating cumulative deficit in IQ among socioeconomically deprived Black children. (Author/SS)

In two experiments using a large scale space and a third using a model of that space, the ability of 3-, 4-, and 5-year-old children to coordinate two perspectives of a large scale space was examined. (Author/SB)

This study assessed the ability of fourth, fifth, and sixth graders and college students to logically include and exclude variables when making inferences about a multivariate "natural experiment" situation. (Author/SB)

This experiment investigated age differences in memory performance and the extent to which rehearsal techniques contribute to these differences. Second and sixth grade children were trained in a variety of rehearsal techniques in an overt-rehearsal free recall task. (Author/SB)

The effects of the presence of an attachment object upon preschoolers' emotionality and discrimination performance in a novel learning situation were evaluated. Blanket-attached and blanket-nonattached children were assigned to one of three task conditions: (1) mother present, (2) blanket present, (3) no familiar object present. (Author/SB)

The central thesis of this study was that maturational rate, or its physiological correlates, influences the development of the organization of higher cortical functions and is therefore an important determinant of sex differences in verbal and spatial abilities. (Author/SB)

Five-year-olds, 9-year-olds, and adults were compared in a successive tachistoscopic recognition task in which size of the first array and the interval between the first array and the second single recognition-test stimulus were varied. (Author/SB)

This study examined (1) whether subjects of different ages tend to rely on different kinds of visual information when given a choice; and (2) whether the ability to use spatial and identity information accurately in a recognition task changes developmentally. (Author/SB)

Studied the utility of cardiac habituation/response recovery as a measure for assessing infant cerebral asymmetries in auditory perception on a dichotic listening test. (Author/SB)

In this study, third and sixth graders were tested in a recognition memory task with short lists of items from either one or two categories to investigate the influence of categorical information on retrieval processes. (Author/SB)

Fifteen mothers were trained to administer tactile-kinesthetic stimulation to their premature infants for 15 minutes four times a day for 1 month. At 4 months of age, experimental infants were compared to 14 controls for neurophysiological development. (Author/SB)

It is hypothesized that adding neutral items to the IT Scale for Children will demasculinize boys' scores by allowing them reasonable alternatives to sterotypically masculine items. (Author/SB)
