Discusses the relationship between insecurity and attachment to soft, inanimate objects. Because attachments to nonsocial objects are common, there is agreement that they do not presage maladjustment. An investigation with 20- to 41-month-olds indicated that attachment to blankets was not associated with general fearfulness, however, certain…

Results indicated that the more frequently the children studied expressed emotion, the older the age of language achievements; and the more time spent in neutral affect, the younger the age of language achievements. (PCB)

A large sample of adults rated a videotape of the activities of an infant whose gender was labeled differently with different subject groups. Labeling the infant "male" resulted in significantly more activities being rated masculine than feminine, whereas the converse was true when the infant was labeled "female." (KH)

Infants, aged one to four months, were tested for developmental shifts in their ability to discriminate internal pattern elements in compound geometric figures. Significant recovery was seen at all ages when any pattern element was altered. No developmental differences in responsiveness to changes in internal versus external figures were observed.…

Investigates whether tactual habituation without the assistance of vision occurs in four- to six-month-old infants. Additionally tests the relevance of a habituation/reaction to novelty procedure in the tactual modality. Results show clearly that tactual habituation occurs in such infants, just as visual habituation does. (Author/RH)

In three experiments, the effect of additional "contextual" elements on the discrimination of the orientation of linear and curvilinear segments was investigated with four-month-old infants. Results suggest that, regarding certain stimuli and techniques of measurement, surrounding contextual segments can aid the discrimination of linear…

Relationship between maternal ratings of temperament and operant learning was examined in 18 2- to 3-month-old infants. Subjects participated in a conjugate reinforcement experiment; mothers of subjects completed the Carey and McDevitt Revised Infant Temperament Questionnaire 2 to 3 days before the learning study. Two temperament dimensions,…

Classified fetuses as accelerators or decelerators based on intrapartum fetal heart rate (FHR). Explored the relationship of the classification with gestational age and neonatal behavior in clinically healthy neonates to provide an empirical basis for using FHR in the study of infant behavior. Subjects were 48 "healthy term" or…

Two studies were conducted to (1) develop measure of infants' executive capacity, defined as difference between infants' most sophisticated level of functioning displayed first in free and then in elicited play and (2) to test several hypotheses regarding relationship between these performance and competence measures of child functioning and home…

Three experiments investigated the dynamics of human infant visual fixation. Results showed that, over a series of trials, four-month-olds fixate longer on a complex than on a simple stimulus. Findings challenge prevailing cognitive-schema theories as a complete account of the dynamics of infant visual fixation. A two-process theory that accounts…

A laboratory procedure was developed for assessing imitation in the second year of life. Results demonstrate that 14- and 24-month-olds can imitate a simple action with an unfamiliar object, both immediately and after a 24-hour delay. Implications for research design and theory of infant memory are discussed. (RH)

An exploratory study was made of the emotional and social functioning of young children having one manic-depressive parent. Semi-naturalistic observations and experimental manipulations of the affective environment were used to assess two-year-olds' regulation of emotion, as well as their aggression, altruism, and affiliative interactions.…

Under equivalent task conditions, assessed object and person concept attainment in securely and insecurely attached infants. Subjects were 16 male and 23 female infants from middle class families. (Author/RH)

Low-birth-weight infants, who received extra stimulation showed improved development through six months of age. (ST)
