The relationship between reflection-impulsivity as assessed by Kagan's Matching Familiar Figures test, and ratings of four personality variables (impulsivity, academic achievement motivation, test anxiety, and extra-version was examined in 68 fifth-grade children. (BRT)

Examines 24 mother/impaired infant dyads to study the quality of interaction using the Ainsworth-Wittig attachment paradigm. Measures of general development and degree of child impairment significantly differentiated "classifiability" of attachment in the Ainsworth scheme. Infants rated higher on a social responsiveness measure were more…

Tested infants in their second year with a box task to determine whether they would show a hand preference in solutions involving complete differentiation of roles for the two hands. (HOD)

Emphasizes the role that motor development may play in determining developmental sequences in other domains, such as haptic or tactile perception and depth perception. Maintains that there is a high degree of fit between the developmental sequence in which certain perceptual sensitivities unfold and the ages at which the corresponding motor…

Examined longitudinally the effects of infants' age, body dimensions, and experience on the development of crawling. Although most infants displayed multiple crawling postures en route to walking, development did not adhere to a strict progression of obligatory, discrete stages. Duration of experience with earlier forms of crawling predicted the…

Infant reaction to adult speech was studied through frame-by-frame analysis of sound films. Infants' actions were found to be synchronized with the organized speech behavior of the adults in his environment. (ST)

Advances in the neurosciences, biomechanics, and behavior sciences, along with attempts to integrate theories and findings across these disciplines, have led to a renewed interest in the study of motor development. Considers the contributions that have led to the reinvigoration of this field of study and its new interdisciplinary outlook. (MDM)

Used National Maternal and Infant Health Survey data to examine effects of poverty and maternal depression on child development. Found that maternal depression and poverty jeopardized development of very young children. Affluence somewhat buffered the deleterious consequences of depression. Chronic maternal depression had severe implications for…

The relation between cognitive and motor performance was studied in a sample of 378 children aged 5-6. Half of these children had no behavior problems; the others were selected for externalizing (38%) or internalizing problems (12%). Quantitative and qualitative aspects of motor performance were related to several aspects of cognition, after…

Concern exists that a constellation of negative maternal emotions during pregnancy generates persistent negative consequences for child development. Maternal reports of anxiety, pregnancy-specific and nonspecific stress, and depressive symptoms were collected during mid-pregnancy and at 6 weeks and 24 months after birth in a sample of healthy…

Studied across a 16-month period, young children of deaf parents showed accelerated early language development, on the average producing their first recognizable sign at 8.5 months, their tenth sign at 13.2 months, and their first sign combination at 17.0 months. Findings are inconsistent with previously reported patterns of synchrony between…

These data appear to support the conception that the speech motor system can act as a mediator of other motor systems when speech'' is experimentally manipulated. (Author)

After reviewing recent contributions to the field of motor development, suggests a pattern formation or dynamics approach to child development as an alternative to the conventional approaches emphasizing maturation (nativist), specific learning experiences (empiricist), cognitive stages (Piagetian), and strategies of encoding and retrieval…

Suggests that studies of the development of children with disorders of motor function afford opportunities, as yet unexploited, to understand the importance of motor function to overall child development. Maintains that Pellegrini and Smith's (1998) review provides a challenge to developmentalists from many disciplines to use their natural model…

Three experiments examined vision's role in infants' grasping of horizontally and vertically oriented rods. Found that infants differentially oriented their hand regardless of lighting and similar to control conditions where they could see rod and hand throughout reach. Findings suggest that infants may use current sight of object's orientation or…
