Attention in 5-7-year-old children was measured at playtime with freely chosen toys. Half of the children were required to verbalize all imaginable actions with the toy attended to least. Verbalization appeared to decrease exploration in a subsequent observation. (ST)

A total of 43 infants were subjected to increasing intensities of a tactile stimulation (air puffs) until a behavioral response occured. All infants displayed increased heart rate responses at threshold. (ST)

Attachment behavior, toy preference, style of play, and activity level were recorded in 17 sets of opposite sex twins observed in a playrrom setting with their mothers. (ST)

Four age groups of boys were given three opportunities to display altruistic behavior. Sharing and helping increased with age. Volunteering to work showed no relationship to age. (ST)

The Children's Personality Questionnaire was used to classify 10-12-year-old children into high-and-low stable groups. Factor analysis for the two groups revealed separate factor structures. (ST)

The experiment measured attention-getting and attention-holding processes independently. Results confirmed the necessity for separating these measures and indicated differences between male and female infants in their demonstration of memory. (JMB)

Second-, third- and fourth-grade children participated in two experiments involving gameplaying. Substantial persistence and generalization of effects of exposure to a peer model were found. (JMB)

Examined the effects of varying degrees of teacher support on middle-class preschoolers' success in cognitive and motor learning tasks. Support was defined in terms of physical proximity, physical contact, and facial and verbal behaviors. (JMB)

Two studies of 7-, 8- and 9-year-olds assessed the effect on cognitive development produced by varying degrees of physical isolation of family dwellings and the consequent variation in the amount of verbal communication children had with peers and adults. (JMB)

The study was designed to determine whether preschoolers' scores on a measure of outer-directedness can be used to predict changes in their Stanford-Binet Short Form IQ's over a 6-month period. (JMB)

A hemispheric specialization of function paradigm was used to test cognitive skill and cognitive style in learning disabled and "normal" boys between the ages of 7 and 12. Discussion emphasizes the need for more information on nonverbal processing skills to aid in developing verbal representational systems. (JMB)

Subjects in kindergarten through 5th grade were classified as task oriented, information seeking or cue dependent. Then an experiment was performed to investigate relationships between these predispositions and the children's performance and self-perceptions as they worked on an external-cue-relevant or cue-irrelevant concept identification task.…

The study aimed to develop techniques for objective recording of mother and infant behaviors, to describe the interactive patterns of black inner-city mothers and their newborns, and to determine the effect of selected background and examination variables on these behaviors and interactions. (JMB)

Second graders, fifth graders, and adults participated in two experiments designed to study the effects of sorting on subsequent recall of unrelated words. (Author/CW)

Examined the relationship of newborns' 1-minute Apgar scores to their 8-month Bayley mental and motor scores and to 8-month classifications of their development as normal, suspect, or abnormal. Also investigated relationships between Apgar scores and race, longevity, and birth weight. (JMB)
