Object substitution masking (OSM) is said to occur when a perceptual object is hypothesized that is mismatched by subsequent sensory evidence, leading to a new hypothesized object being substituted for the first. For example, when a brief target is accompanied by a longer lasting display of nonoverlapping mask elements, reporting of target…

Attempted to replicate the pitch discrimination findings of previous research and expand them to the modality of color discrimination in a sample of 899 teenagers and adults by correlating 2 sensory discrimination measures with the general factor from a battery of 13 cognitive ability tests. Results suggest that sensory discrimination is…

Textons are elongated blobs of specific color, angular orientation, ends of lines, and crossings of line segments that are proposed to be the perceptual building blocks of the visual system. A study was conducted to explore the relative memorability of different types and arrangements of textons, exploring the time course for the discrimination…

Examined the relationship between cognitive style and reading readiness in 104 kindergarteners before and after a visual discrimination treatment designed to modify conceptual impulsivity. Correlations were also obtained between errors and latencies on the Matching Familiar Figures Test and performance on the Metropolitan Readiness Test. No…

Twenty-five older adults with age-related macular degeneration were separated into one of three groups: in-clinic training, take-home-training, or no-training. After testing, results showed that the ability to distinguish figure from ground is an improvable skill with the take-home group improving the most. (Author/DB)

Preschoolers learned colors more rapidly than sizes and forms when cup stimuli were used. They learned sizes and forms more rapidly than colors when face stimuli were used. (RL)

Investigators in this study looked for conditions that can rapidly establish continuous stimulus control of continuous response variations, or "response mapping." Unlike previous research in stimulus control, where a single stimulus comes to control a single response, 36 5-year-old children received errorless discrimination training at…

In a study of oddity performance, subjects were required to choose one distinct bimodal stimulus from a display that included other stimuli that did not differ from each other. Oddity performance was evaluated with both reversal assessments and assessments with new stimuli. The usefulness of bimodal training in oddity learning was demonstrated.…

Training programs for auditory and for visual figure-ground perception were constructed and tested with brain-damaged and mentally retarded children. Training groups showed higher gain scores than the control group on both tests, but the effect was significant only for visual training on visual figure-ground perception. (Author/SJL)

Children at the preoperational and concrete operational levels are influenced by a variety of perceptual cues other than subject matter when classifying paintings. While younger children had little difficulty in classifying paintings done in three stylistic categories, older children were able to perform this task with significantly greater…

The result of a number of experiemental studies of human auditory and visual information processing behavior and their possible relationship to the student pilot's acquisition of flying skill were explored in terms of a conceptual model developed for this study. The results were interpreted in terms of the potential interfering effects of the…

In the first experiment, the development of the ability to copy alphabet letters by black males aged 3-9 (middle and low S.E.S.) was studied, using a newly-developed scoring system. In the second experiment, kindergarteners learned to associate letter names with six lower-case printed letters by the anticipation method. The addition of an…
