Mobile devices have been increasingly utilized in informal learning because of their high degree of portability; mobile guide systems (or electronic guidebooks) have also been adopted in museum learning, including those that combine learning strategies and the general audio-visual guide systems. To gain a deeper understanding of the features and…

The variability of stereotypic body-rocking motions of eight adults with severe/profound mental retardation was examined through kinematic analysis and compared to a matched nonretarded group of adults. Inter- and intra-individual variability was, on average, higher for the individuals with mental retardation. Results suggest that low variability…

Determines the time course of circulating cortisol following circumcision in 80 healthy newborns and investigates whether changes in behavioral state following circumcision in anyway paralleled the adrenocortical time course. Adrenocortical and behavioral data indicated that subjects were able to cope with circumcision trauma. Cortisol levels…

Quantifies behavioral periodicities or cycles during face-to-face interaction between three- and five-month-old term and preterm infants and their mothers. Compares the temporal organization of social interaction between term and preterm infants. Spectral and cross-spectral techniques showed the existence of periodicities. Differences were found…

Eight German and eight Italian children were observed during their first year in preschool. Cultural differences and similarities in play and behavior and sex differences are reported. Findings suggest that strategies that children use to enter kindergarten or a new group exist universally. (Author/RH)

Examines the social behavior of 34 preschool children, observed both at home and in preschool, to determine patterning interactions among siblings and consistency in children's interactions with siblings and peers. Concludes that children's behavior at home is most affected by relative age of their siblings. (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)

Compares the separation distress of 26 19-month-old Downs Syndrome infants in the Strange Situation with that of 43 normal infants who were observed at 12 1/2 and 19 1/2 months to assess whether Downs Syndrome infants responded more similarly to cognitively comparable normals than to age-comparable normals. (HOD)

Examines the functioning of toddlers with physical anomalies (but without central nervous system damage) in comparison to premature toddlers (with similar deviant early experience but no deviant physical appearance) and to normal toddlers. Premature and disabled toddlers performed more poorly than normal toddlers in measures of social initiative,…

Social competence of 239 students with and without learning disabilities (LD) was followed from kindergarten through fifth grade. Students with LD demonstrated the same trends in social competence as non-LD students. Students with LD differed significantly from average-high-achieving non-LD students on social skills and behavior problems, but not…

Studies the frequency with which preschool children used 11 play centers, engaged in social and nonsocial activities in each play center, and interacted positively and negatively with each other. (HOD)

Eighteen cases of disintegrative psychosis (DP) were compared with 52 cases of infantile autism (IA) with speech loss and 145 IA cases without speech loss. DP cases showed clearer regression after more satisfactory development than the IA cases with speech loss, and by age seven were more severely retarded but similar in autistic symptomatology to…

Aware of some educators' concerns that computers isolate children and are too abstract for chilren under the age of eight, two studies investigated young children's use of LOGO and their interactions with the computer. Data were collected on kindergartners working in a public school computer lab and on preschoolers using computers in a…

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)

Research has shown that drug use tends to increase during the college years, implying that college students have a more favorable view of drug use than high school students. To compare the attitudes of high school (N=367) and college students (N=260) toward nine recreationally used drugs, a semantic differential technique was used. Statistically…
