Twelve children were observed monthly between the ages of 1 and 2 1/2 to determine whether the situational features expressed by their single words were combined later in their two-word utterances. (JMB)

Third and fourth graders from middle and low income schools participated in a study of the relationship between social skills, social interaction and popularity. (JMB)

Naturalistic observations were made of the interactions between 4- to 8-year-old boys and their parents after the parents had been given a socially desirable or undesirable response set. (JMB)

Physiological responses of sixteen hyperactive children between the ages of 6 and 12 were measured in order to assess characteristic attentional deficits and responses to methylphenidate. (JMB)

Examines the manipulative strategies of 2- to 6-year-olds in terms of three structural principles--hierarchical complexity, interruption and role change--which are formally parallel to dimensions of language structure. Paper includes an extensive discussion of related studies. (JMB)

Investigates the extent to which the parents of adequately functioning children, as opposed to the parents of "disturbed" children, support their statements of approval or disapproval with matched affect and with conviction in their tone of voice. (Author/CW)

Investigates the effects of father absence and perceived maternal behaviors on the moral behavior, judgment, and affect of preadolescent boys. Also tests for differences between sons of divorcees and widows and between boys who were at different ages at the onset of father absence. (CW)

Studied the effects of the relative and absolute salience of three dimensions (form, color and position) on the ability of four- and six-year-olds to employ multiplicative classification. (CW)

Tested two hypotheses to account for results of an earlier study in which preschoolers failed to display differential behavior when instructed to memorize itmes or merely to examine them perceptually. Subjects included second and fifth graders as well as preschoolers. (CW)

The influence of an older brother on the physical activity or passivity of younger brothers and sisters was examined through teacher observations of children in kindergarten through sixth grade and through self reports of college students. Study included whites and Mexican Americans. (CW)

Compares the performances of "impulsive" and "reflective" urban middle class children on a picture completion task designed to measure creativity. (CW)

Eighty nursery school and upper elementary school children selected picture cards from varying stimulus arrays in order to indicate their preference for unorganized mixed collections, groups of identical cards, or sets of different cards that together formed a whole figure. (CW)

Evaluates the use of 5-year-olds' scores on a picture reading task to predict the children's later reading performance. Suggests that the picture reading task measures differences in children's understanding of the nature and purpose of reading. (CW)

Kindergarten and second grade children participated in a replication and extension of Hartup's earlier study concerning the effects of continuous nurturance and nurturance withdrawal on children's behavior. The author suggests that future research be focused on less complex contrasts between adult interaction patterns. (CW)
