The reading comprehension and visual word recognition in 50 deaf children and adolescents with at least 3 years of cochlear implant (CI) use were evaluated. Their skills were contrasted with reference data of 500 deaf children without CIs. The reading comprehension level in children with CIs was expected to surpass that in deaf children without…

This study identified new methodological variables which might affect the responses of second and third grade children to Piagetian conservation tasks. (GO)

Four experiments investigated three- and four-year-old children's knowledge of projective size-distance and projective shape-orientation relationships. Results indicated that preschool children's understanding of these relationships seems at least partly cognitive rather than wholly perceptive, providing further evidence for the acquisition of…

Two experiments tested infants' sensitivity to properties of point-light displays of a walker and a runner that were equivalent regarding the phasing of limb movements. Found that 3-, but not 5-month-olds, discriminated these displays. When the symmetrical phase-patterning of the runner display was perturbed by advancing two of its limbs by 25…

Preferences for moving versus static bars were assessed in 8-, 16-, and 20-week-old infants. Findings revealed that at both 16 and 20 weeks, preferences were affected only by the velocity of the bar's movement. This effect persisted at 20 weeks even when static reference features were added to the display. (RH)

Two studies examined three- and five-year-old children's and adults' explicit and implicit memory for pictures, using measures of recognition memory and perceptual facilitation. Found that recognition memory and perceptual facilitation were related for adults but not for children at either age. (MDM)

Tested 7 and 10 month olds for perception of correlations among facial features. After habituation to faces displaying a pattern of correlation, 10 month olds generalized to a novel face that preserved the pattern of correlation but showed increased attention to a novel face that violated the pattern. (BC)

The aim of the two present experiments was to examine the ontogenetic development of the dissociation between perception and action in children using the Duncker illusion. In this illusion, a moving background alters the perceived direction of target motion. Targets were held stationary while appearing to move in an induced displacement. In…

Children's speed and fluency of writing has elsewhere been shown to correlate with the quality of their composition. Here, we compared speed and fluency of text production when children aged between 6 and 11 used either a pen or a computer keyboard. Younger children were reliably slower and less fluent when writing at a keyboard. All children were…

Young preschool children aged 2 and 3 years were exposed to a novel paradigm designed to train visual perception skills. The results indicate that children of this age can be trained to perform a percept deprivation task that requires a sophisticated understanding of attention not normally mastered until 3.5-4 years. Results are discussed with…

Studied the effects of the relative and absolute salience of three dimensions (form, color and position) on the ability of four- and six-year-olds to employ multiplicative classification. (CW)

Four experiments were conducted to investigate the extent to which infants of different ages respond to facelike drawings on the basis of stimulus complexity and/or resemblance to the human face. Infants' responses to stimulus patterns were assessed using the corneal reflection technique developed by Robert Trantz. In the first two experiments,…

A sharp improvement in children's understanding of the role of visual perception and linguistic communication in knowledge functions was found between the ages of three and five years. (PCB)

Infants, aged one to four months, were tested for developmental shifts in their ability to discriminate internal pattern elements in compound geometric figures. Significant recovery was seen at all ages when any pattern element was altered. No developmental differences in responsiveness to changes in internal versus external figures were observed.…

One- and two-month-old infants were shown schematic drawings of a human face with features arranged (1) naturally, (2) symmetrically but scrambled, and (3) asymmetrically and scrambled. Two-month-olds discriminated among all arangements and preferred the natural arrangement; one-month-olds showed no discrimination or preference. (Author/DB)
