The ability of 2-year-olds to carry out a forward search strategy was examined in a study of performance on platform rotation problems. One group of children was tested successively on two analogous versions of a task. The two versions shared the same underlying principle but had different surface characteristics. A control group was given an…

The experiences of a home counselor for a blind infant intervention program are summarized. Discussed is the role of four areas in successful programming: (1) exposure, or the need for hands-on experience with the world to understand cause/effect and promote imagination; (2) experience of things in such a way as to provide realistic associations…

This study was designed to determine whether infants actually play with crib toys, and whether the toys affect the duration or onset of sleep. (CS)

Reported is the case of identical twin girls whose neonatal anemia (fatal in one case) was found to be due to Kell (a minor blood group) incompatibility. (DB)

This paper discusses recent studies of the adult visual evoked potential (VEP) which have indicated that specific components of the complex waveform obtained are related to the three basic color processes, and that these components interact in ways that seem to agree with opponent-colors phenomena. The components identified as being related to the…

This study addressed three major questions pertaining to habituation of visual attention in infants: (1) does habituation occur gradually? (2) how do fast and slow habituators compare in their response to discrepancy? and (3) does intervening stimulation produce interference with infants' visual recognition memory? The subjects were 36 17-week-old…

Product-moment correlations between Stanford-Binet IQs of 151 women and the Gesell Developmental Quotients of their illegitimate children were significant when the children were approximately 2 months old and residing in institutions. After the children were adopted, the correlations dropped at first but then increased in the final tests given at…

Two experiments are reported in which cardiac habituation of the orienting response to pure tone stimuli was studied in well-nourished and malnourished male Guatemalan infants. Results indicated a fundamental attentional deficit in the malnourished group. (GO)

Recommends criteria for determining adequate sample size for the use of Mean Length of Utterance (MLU) as an indicator of early language development. (BD)

Reports four experiments in which infants' recognition memory (defined by novelty preferences) was found to be improved by providing five- to seven-month-old infants with discriminable but related targets during the familiarization period. Facilitation of recognition was found for both photographs of faces and abstract patterns. (JMB)

Asserting that play encourages development of the cognitive map, this article describes the development of a cognitive map and explores the function of play in that development. (JC)
