Reports on three experiments that assessed the attentional responses of 4-month-old infants to frequency-modulated sweeps corresponding to the frequency range of adult-to-infant and adult-to-adult intonational patterns. (HOD)

This paper is concerned with the unfolding of human marks, beginning with scribbling, and their contribution to developing literacy. The paper argues that children's scribbles reveal a neural substrate destined for marks and influence that substrate significantly, cuing what is distinctly human in linguistic behavior and consciousness, or symbolic…

This study used saccadic eye movements to assess visuospatial attention in 53 normal children (ages 8-15). Saccadic latency, the ability to suppress extraneous saccades during fixation, and the ability to inhibit task-provoked anticipatory saccades all improved with age. Developmental patterns varied by task. Analyses of age-related changes may be…

Toddlers with Down's syndrome (n=42) were presented with situations in which the primary focus alternated between an object stimulus and a social stimulus. The experimental subjects monitored their environment in the same manner as did the 25 control subjects (matched for mental age) during object mastery but had a more focused attention style…

Twelve children (ages 7-8) with attention deficit hyperactive disorder were administered the Selective Auditory Attention Test twice: after the administration of methylphenidate and after the administration of a placebo. Results revealed no simple drug effect but a strong order effect. (Author/JDD)

This study, involving 40 normal-hearing 6 year olds, substantiates the form equivalence of the Selective Auditory Attention Test. Analysis shows equal mean difficulty and significant correlations between lists in quiet and between lists presented with competing speech. (Author/JDD)
