The primary objectives of this research program were the development of a battery of tests to investigate the effects of brain impairment on sensory and perceptual functioning. The Sensory-Perceptual Exam (SPE) contains measures intended to evaluate both relatively "pure" sensory functions, as well as those which involve more integrated…

The results of this study showed no significant differences in the size estimation levels of acute and chronic schizophrenic and nonschizophrenic psychiatric patients. Also, there were no significant differences when these groups were subdivided on the basis of both premorbid adjustment and paranoid status. (Author/CG)

Results of this study suggest that Negro mentally retarded children are more proficient on sensory motor tasks than are their white counterparts. (Author/MG)

Humans and pigeons were trained to discriminate between 2 views of actual 3-D objects or their photographs. They were tested on novel views that were either within the closest rotational distance between the training views (interpolated) or outside of that range (extrapolated). When training views were 60? apart, pigeons, but not humans,…

Two hypotheses were tested in this study: (1) that the elaborateness of children's descriptions would increase with grade level, and (2) that there would be a decrease in peripheral descriptions and an increase in central descriptions with grade level. A total of 211 kindergarten through eighth-grade students were instructed to describe an adult…

A study sought to ascertain the effect, if any, exposure to different temperatures would have on an individual's ability to discriminate between different tactile stimuli. Ten young adult males were repeatedly subjected to emersion of their dominant hand in water ranging in temperature from ice, to 105 degrees Fahrenheit (F), in increments of 15…

Butler (1980) compared errors representing intrusions and mislocalizations on 3x3 letter displays under pattern-mask versus no-mask conditions and found that pattern masking increased character mislocalization errors (naming a character in the display but not in the target position as being the target) over intrusion errors (naming a character not…

A scheme, using features in a cartoon-like human face to represent variables, is tested as to its ability to graphically depict multivariate data. A factor analysis of Harman's "24 Psychological Tests" was performed and yielded four orthogonal factors. Nose width represented the loading on Factor 1; eye size on Factor 2; curve of mouth…

THE ASSUMPTION THAT READING DISABILITY CAN RESULT FROM A GAP BETWEEN THE DEVELOPMENTAL MATURITY OF CHILDREN AND THE DEMANDS OF A BEGINNING READING PROGRAM CARRIES WITH IT THE PROBLEM OF ASSESSING DEVELOPMENTAL STATUS. A LONGITUDINAL STUDY CONDUCTED TO DERIVE A METHOD FOR IDENTIFYING SIGNS OF IMMATURITY RELATED TO LATER READING DIFFICULTIES USED…

The extent to which sex differences on a mental rotation test were related to ocular dominance, handedness, and familial handedness was explored. The Vandenberg revision of the Shepard-Metzlar mental rotation test was administered to 206 college students. The test consisted of 20 criterion figures, each followed by two correct and two incorrect…

The first step in learning to read is to recognize the visual language code as equivalent to the auditory code. The next step is the translation between auditory and visual information as well as between temporal and spatial organizations. The factors contributing to such translations are divided into six subprocesses: auditory sequence…

A test for sensitivity to binocular disparity and a shape perception test were administered to four-month-olds. Results indicated that disparity-sensitive infants could perceive three-dimensional-object shape from kinetic and binocular depth information. (PCB)

A factorial design was utilized to investigate the effects of race on expressers and perceivers on the perception of seven emotions. Overall results indicated significant effects. (DM)
