This study explores the development of visual self-recgonition by examining the effect of rouge application on the subsequent mirror behavior of 96 infants, ages 9-24 months. Each infant was observed in front of a mirror in four consecutive conditions: (1) with no rouge applied to infant's nose (baseline), (2) with a dot of rouge on infant's nose,…

This report is based on a longitudinal analysis of physical-contact interaction of mother-infant pairs throughout the first year of life. The sample consisted of 26 middle-class mother-infant pairs who were observed in their homes for four hours once every three weeks. During each visit, the observer made a running record of everything that…

Studies of the infant's distribution of attention to stimuli of varying complexity, and of his differential attention to familiar versus novel stimuli (discrepancy), have attempted to shed light on the development of cognitive structures in the non-verbal infant. The subjects have typically been normal infants ages 4 to 6 months. For testing, the…

This manual describes the Caregiver Language Observation Instrument, a device useful for observing the language behavior of caregivers in infant day care settings. Eleven categories of language behavior are recorded: approval, disapproval, cautioning, soothing, talking to, questioning, labeling, elaborating, singing, directing, and imitating. The…

The following are sketched in outline form: (1) functional antecedents and their implications for language--assimilation, accommodation, circular reactions/ feedback processes, classification, discrimination, functional equivalence, representation, transformation, communications; (2) semantic antecedents and their implications for language--human…

This report is concerned with systems useful for observing parent-child behavior. Part I. discusses observations in contrived situations, unstructured situations; in neighborhoods, laboratory, home and classroom. The paper details the point-time sampling approach, intersession rating procedure, anecdotal records, diary descriptions, (topical and…

A study was conducted in which the infants' behavior was allowed to control stimulus duration. A group of five infants were tested once a week from 3 through 14 weeks of age. A second group of five infants were tested once a week from 8 through 14 weeks of age. A third group of 18 infants were tested once at 3, 8, or 14 weeks of age. Once a…

Vocalizations of two female infants, recorded over a five-week period after the first emergence of cooing were studied. It was found that the features of the more primitive sound types regrouped themselves in comfort sounds. The implications for theories of prespeech development are discussed. (EJS)

Provides an update of information on infant nurturance and early learning of special interest to providers of services to parents and infants. (BR)

The cry sounds of 12 well-nourished and 12 malnourished male infants were compared using behavioral and acoustic measures. (BRT)

Videotapes were made of the prehensile activity and looking behavior of 2- and 5-month-old infants in the presence of objects placed within and beyond possible contact distance. (BRT)

The effect of four social learning conditions on early language acquisition was explored, along with comparisons between learning whole words and learning the component sounds of the words. Subjects were 20 infants aged 9 to 15 months. (MS)

Vocalizations of infants were classified and analyzed in a longitudinal sample of infants ranging in age from 2 to 14 weeks. Results suggest that infants performed different types of vocalizations that can be interpreted as affective states from 2 weeks of age on. Parents responded with a highly diversified pattern of reactions to different infant…

Investigated the relationship between maternal alcohol consumption and infant attachment behavior at one year of age. Infants were classified as secure, insecure-avoidant, insecure-ambivalent/resistant, or insecure-disorganized/disoriented. More infants of mothers who had consumed more alcohol were insecure in comparison with infants whose mothers…
