Infants with visual impairment often require additional interaction from adults to reinforce behaviors that lead to competency at mealtimes, but parental and professional confidence in teaching these skills is often limited. In the following collective case study, the authors, a speech/language pathologist (S/LP), occupational therapist (OT), and…

This commentary endorses J. Kagan's (2008) conclusion that many of the most dramatic findings on early perceptual, cognitive, and social competencies are ambiguous. It supports his call for converging research operations to disambiguate findings from single paradigms and single response indices. The commentary also argues that early competencies…

This study examined changes in rhythmic arm shaking and laterality biases in infants observed longitudinally at three points: just prior to, at, and just following reduplicated babble onset. Infants (ranging in age from 4 to 9 months at babble onset) were videotaped at home as they played with two visually identical audible and silent rattles…

Comparisons of age and test score correlations, comparisons of cross-sequential means, and trends of means for diagnostic subgroups and normal controls suggest developmental delay for all measured skills at all ages for autistic and schizophrenic children. Findings also suggest a trend for steady prepubertal cognitive skill development, followed…

Serial habituation of visual fixations was investigated through a design permitting cross-sectional, within-subject longitudinal, cohort longitudinal, and time-lag analyses. Results suggested that for all ages habituation was under way to the parts of the stimulus in order of the realitive saliencies. No one methodology appeared to significantly…

Infants were tested at 5, 8, and 13 months of age for numerosity perception. Subjects observed displayed figures on a screen moving at constant speed with irregular trajectories and occasional occlusions. Results demonstrated that discrimination of units, and not of characteristic patterns, underlies numerosity perception. (BC)

Evaluates models of infant visual preferences with predictions based on the physical attributes of visual patterns using pairs of schematic faces and abstract patterns identical except for contrast reversals. Results suggest that a fundamental change in the determinants of visual preference occurs postnatally between 6 and 12 weeks. (Author/RWB)

This paper describes a series of longitudinal experiments which dealt with the development of object awareness in infants, ages 6-18 months. The experiments were designed to document and evaluate Piaget's account of this development. The studies focused on two types of phenomena: (1) when infants first find an object hidden in one place, they will…

Over half the world's population speaks a tone language, yet infant speech perception research has typically focused on consonants and vowels. Very young infants can discriminate a wide range of native and nonnative consonants and vowels, and then in a process of "perceptual reorganization" over the 1st year, discrimination of most…

Examined, over a 10-year span, continuity in individual differences in cross-modal transfer to visually recognized shapes that had previously been felt but not seen. Found that cross-modal performance showed a left-hand advantage at 11 years. Cross-age correlations were significant when tactual exploration at 11 years was done with the left hand.…

The development of and relationship between early language, symbolic play, sensorimotor skills, and social development were examined in a longitudinal study conducted in Japan with two young autistic males who were observed from the approximate ages of 2 to 4 years in clinic, day care, and home settings. One child acquired speech; the other did…

Noting that the last 30 years have seen enormous increases in the understanding of infancy, this book examines the current state of knowledge regarding infant development. The book's contents stem from meetings of the British Infancy Research Group. Although the book was intended for advanced undergraduates, it would also be useful for advanced…

This paper describes the purposes and procedures of a longitudinal study designed to: (1) relate mother-infant interaction patterns to infant age, sex, and social class; (2) relate mother-infant interaction patterns to infant sensory-motor development; and (3) to examine the relationship between infant sensory-motor development and infant sex and…

This is a partial report of a longitudinal investigation designed to assess the psychological effects of an experimentally conducted day care program on children during the first 30 months of life. The experimental subjects were Chinese and Caucasian children from working and middle class families who were cared for at a special group care center…

The third Fenno-Hungarian Conference on Developmental Psychology covered four main concepts: the historical roots and development of social competence through three generations, parent-child interaction, parenthood, and the development of socio-cognitive competence through childhood and adolescence. A series of papers was presented addressing the…
