Some young children presented with unidimensional and nonverbal conservation tasks were able to give a conservation response if they could answer with a picture instead of orally. (Editor)

Construct validity of the Personal Orientation Inventory was investigated. A sample of graduate students were administered the inventory immediately after a stressful experience and again two weeks later after the stressful experience had been resolved. Two of the twelve inventory subscales, Self Regard and Self Acceptance showed significant…

Investigates perceptions of the universe of (n=232) first-year physics students from two South African universities. Compared results with Aristotelian and Newtonian views as well as with those of children as revealed in a literature survey. Results also showed that a statistically significant larger number of African than European students have…

Content analysis of the Columbia Mental Maturity Scale and the Test of Nonverbal Intelligence (TONI) revealed differences in the nature of perceptual and conceptual items. Both language-impaired and normal-language children performed significantly better on perceptual-type than conceptual-type items. The predominance of perceptual items was…

Research findings were reviewed on the Auditory Visual Combined Discrimination Test, which can be used with severely and profoundly mentally retarded persons to assess basic position, visual, and auditory discriminations. The test was found to be reliable and predictive of client performance in classroom learning, language, and vocational tasks.…

The scores of 15 children (ages 5-10) with learning disabilities on the Test of Visual Perceptual Skills and the Developmental Test of Visual Motor Integration revealed that visual perception and visual motor skills are separate, though related, functions and that visual motor scores were significantly lower than visual perception scores. (JDD)

A study examined how well children could discriminate matches from nonmatches of multicomponent stimuli within the prototypic mental rotation task and how long it would take them to make such discriminations. The goal was to determine whether children are differentially sensitive to the various spatial features of visual stimuli and whether…

Highlights the importance of a combined approach to the assessment of dysarthria with reference to two case studies of individuals with dysarthric speech: a 32-year-old adult who suffered a severe closed head injury and a 9-year-old child who experienced a cerebrovascular accident involving the basilar artery.

People presume that the light source in pictures comes from above, and there is some evidence that this phenomenon also demonstrates lateral biases. When investigators present multiple ambiguous stimuli or visually complex objects, people assume that the source of light is from above, and to the left. However, when single relatively simple stimuli…

We investigated how different psychophysical procedures affect frequency discrimination performance in children. Four studies used a design in which listeners heard two tone pairs and had to identify whether the first or second pair contained a higher frequency target tone. Thresholds for 6-and 7-year-olds were higher than those for 8- and…

During self-motion, the world normally appears stationary. In part, this may be due to reductions in visual motion signals during self-motion. In 8 experiments, the authors used magnitude estimation to characterize changes in visual speed perception as a result of biomechanical self-motion alone (treadmill walking), physical translation alone…

In 3 studies, participants viewed sequences of multiattribute objects (e.g., colored shapes) appearing with varying frequencies and judged the likelihood of the attributes of those objects. Judged probabilities reflected a compromise between (a) the frequency with which each attribute appeared and (b) the ignorance prior probability cued by the…

Meanings given to the term "perception" are discussed in this paper and two categories of perception theories having implications for instructional media research are identified. One category is described as extroverted because it includes theories primarily concerned with characteristics of external stimuli and the influence that the…

Lowenfeld (1945) developed a series of six instruments which could be used to identify perceptual abilities. For this study, the visually oriented person was defined as the objective viewer of the environment, while the haptic person was defined as a person who uses the eyes only when forced to do so and relates to his environment subjectively. He…
