Finger gnosia and fine motor skills (FMS) are assumed to play a key role in the development of arithmetic abilities, but their contribution to early numerical skills (i.e., enumeration skills and cardinality) has received little attention so far. The purpose of this study was to investigate the predictive value of finger gnosia and FMS to…

Students often perform arithmetic using rigid problem-solving strategies that involve left-to-right-calculations. However, as students progress from arithmetic to algebra, entrenchment in rigid problem-solving strategies can negatively impact performance as students experience varied problem representations that sometimes conflict with the order…

The purposes of this study were to identify if correlations exist between the eight sub-components of visual perception including eye hand coordination, position in space, copying, figure ground discrimination, spatial relations, visual closure, visual motor speed and form constancy, and handwriting ability. The studies also further determined…

Previous studies have indicated that visual-auditory temporal acuity is reduced in children with autism spectrum conditions (ASC) in comparison to neurotypicals. In the present study we investigated temporal acuity for all possible bimodal pairings of visual, tactile and auditory information in adults with ASC (n = 18) and a matched control group…

Purpose: The study addressed three research questions: Does lipreading improve between the ages of 7 and 14 years? Does hearing loss affect the development of lipreading? How do individual differences in lipreading relate to other abilities? Method: Forty children with normal hearing (NH) and 24 with hearing loss (HL) were tested using 4…

The aim of the study was to prospectively assess the differences in participation and sensory modulation between late preterm infants (LPI) and term babies, and to predict it by LPI characteristics. The study population includes 124 late preterm infants at gestational age between 34 and 35 6/7 weeks who were born at the same medical center. The…

Used a multivariate approach and longitudinal design to examine the relationship of early perceptual and cognitive development in first grade, to school achievement in fourth grade. Results indicated variables used to predict achievement differed between the sexes, and sex as a predictor variable depended upon area of achievement studying.…

Two processes have been hypothesized to underlie improvement in perception: attunement and calibration. These processes were examined in a dynamic touch paradigm in which participants were asked to report the lengths of unseen, wielded rods differing in length, diameter, and material. Two experiments addressed whether feedback informs about the…

This report presents a methodology for examining perceptual development in the arts and describes a study based on this methodology. The purpose of the study was to chart the developmental course of perceptual skills used in the arts and to investigate whether these skills generalize across art forms and aesthetic properties or whether they are…

Two groups of disabled readers, ages 8 and 11, were tested. Perceptual abilities related more strongly for younger students, while intelligence related more strongly for older students. Questions are raised about the validity of using expectancy formulae with younger disabled readers and the "learning disabilities" approach with older disabled…

Early intervention approaches for facilitating motor development in infants and children with Down syndrome have traditionally emphasised the acquisition of motor milestones. As increasing evidence suggests that motor milestones have limited predictive power for long-term motor outcomes, researchers have shifted their focus to understanding the…

The battery of perceptual and perceptual-motor tests (including one fine and two gross perceptual-motor tasks, and one visual and two auditory perceptual tasks) were useful for prediction of cognitive performance one year later at kindergarten age. However, cognitive achievement in first grade, and even more so in second grade, was best predicted…

Since adolescent depression has become more frequently recognized, its manifestations need to be identified. To explore cognitive-perceptual distortions in depression as a function of generational (adolescent vs. adult) differences, 25 adult and 25 adolescent female inpatients diagnosed as depressed were administered the Beck Depression Inventory…

A study of 30 sign language interpreters (N=30) attempted to isolate cognitive, perceptual, psychomotor, and affective factors predictive of effective interpretive skills. Analysis revealed that family background (hearing or deaf family members) significantly affected certain personality traits and interpretive skills. (Author/CB)

Five and seven year olds were able to correctly distinguish between factual and fictional television programs and test clips, based upon genre of program, production features, content. Age and vocabulary scores predicted accuracy of factuality judgments, but television viewing history did not. Older children understood better than younger ones…
