Language And Cognition

The interdependence of psychological functions such as motor skills, perception, language, and cognition has been well documented by many (Hebb, Piaget, Kephart, Johnson and Myklebust, Frostig, Ayres, and de Quiros, to name a few). It is also quite well established that disorders of perception are concomitants of early academic problems. It is reported by Crosby and Liston (1976) that at least 10 per cent and perhaps as many as 15 per cent of children entering first grade may have neurologically based problems which will inhibit their academic progress. The process of learning is highly dependent upon adequate perceptual functioning (ability to interpret stimuli from the sense organs) as well as sensory integration (ability to filter, organize and integrate sensory information).

Instruments intended to measure perceptual functioning present a major thrust in the learning disability field for differentiating learning disabled from normal peers. This investigation is an attempt to improve on some of the limitations noted in other research efforts in this area. First, only instruments which are generally accepted as measures of perceptual and perceptual-motor functioning were used. Second, in order to avoid ceiling effects, all subjects were within the age range for which normative data on the selected instruments were available. Third, IQ scores and chronological age were partialled out in order to remove the effects of these variables.

Method Of Constant Stimuli

Research relating brain stem stimulation and cortical selectivity by Lindsley (1957) led Venables (1963) to utilize a score from a perceptual discrimination task (two-flash fusion threshold, T.F.T.) to examine hypotheses relating arousal level to perceptual dysfunction and schizophrenic symptoms. Other work failed to confirm the results (Hume and Claridge, 1965), possibly due to the unsuitable method of determining T.F.T., a method of constant stimuli. The following experiments were based on the proposition that perceptual functioning is related to arousal level, and also attempted to resolve confusions arising from earlier studies by control of possible sources of error in the experimental situation.

Children with spina bifida manifesta have been described as having a higher than average probability of visual-perceptual impairment. However, documentation with standardized test instruments of visual-perceptual functioning observed for this group has been meagre. In the present study, approximately 60% of Ss examined failed to show age-appropriate performance on the Frostig Developmental Test of Visual Perception. Performance on the Frostig test was analyzed for these Ss in relation to level of spinal cord lesion, presence or absence of hydrocephalus, age, IQ. Possible causal bases for visual-perceptual impairment in these children and implication for training are discussed.
