This study examined the relation between self-representation and brain development in infants and young children. Self-representation was assessed by mirror recognition, personal pronoun use, and pretend play. Structural brain images were obtained from magnetic resonance imaging (MRI). Brain development was assessed by a quantitative measure of…

Paper presented at the Merrill-Palmer Institute on Research and Training of Infant Development (Detroit, Mich., Feb. 15-17, 1968).

Examined whether early differences in stress reactivity were related to self-recognition at 18 months. Found that self-recognition was related to greater cortisol response and less rapid quieting at 6 to 18 months, whereas cortisol and quieting responses of 2- to 4-month-olds did not differentiate self-recognizers and non-self-recognizers,…

Investigates the relationship between self-recognition and self-evaluative emotions in two studies on 27 children aged 9-24 months and 44 children aged 22 months. The results of both studies indicate that embarrassment but not wariness was related to self-recognition. (RJC)

Article describes results of a longitudinal study on measuring intelligence of infants. Results cast serious doubt on the notion of measuring general intelligence in the period of infancy. (PS)

This study was designed to test two alternate hypotheses regarding the meaning of increased lateral head movements in infants during experiments in which the mothers' voices were displaced from their faces. One interpretation is that the lateral looking responses of the infants are attributable to maturational effects on the infants' physiological…

Suggests that the central focus of the article by Raver and Leadbeter (PS 521 712) in this issue is the ways individuals know. Examines two ways of knowing, verbal responses to questions and action without verbal response; and outlines a four-level developmental sequence of knowing that develops from one's own knowing to having a perspective on…

The most impressive class difference in one-year-old infants revealed by this study was that lower-class infants vocalized considerably less in the playroom than did middle-class infants. (Authors)

This study examined the social labels which are first used by infants, social differentiation on the basis of labeling behavior, and overgeneralization of social labels. Subjects were 81 infants from 9 to 36 months of age. The 9- to 24-month-olds were shown slides of themselves, their mothers, their fathers, and unfamiliar children, babies, and…

Data from a variety of infant intelligence scores make clear that it is not possible to consider (1) that infant intelligence is a measurable, stable and unitary construct, (2) that there is a general g factor easily discernible in infancy, (3) that there is stability of scores both within and across scales, or (4) that there is predictability…

In Western societies, the study of emotional development has been retarded by the view that it is less important than cognitive development, but a review of relevant literature indicates emotional well-being may be as important as cognitive growth in determining life outcomes. Cognitive skills, physical health, and emotional well-being are all…

Three related experiments were conducted to investigate the effects of novel and familiar stimuli on infant attention. The procedure in each of the experiments was to place an infant before a matrix panel composed of six rows of six lights. Two patterns of lights were used to obtain the infants' fixation time: (1) a point pattern, a single…

This longitudinal study examined the interrelationship between sex of the child and sex of the parent on the expression of attachment behaviors during the child's first 2 years. Special consideration was given developmental changes in the attachment structure and the relationship of attachment to cognitive development. Ten boys and 10 girls were…

This study explored the relationship between the mother-infant interaction and the concurrent perceptual-cognitive and intellectual status of the infant. One hundred and eight-nine 12-week-old infants were given a battery of perceptual-cognitive tasks, including the Mental Developmental Index (MDI) of the Bayley Scales, the Corman-Escalona Scales…
