This paper describes the physiological "eye noise" effect of line contrast in maps and considers the effect of line contrast on the direct picture of terrain surface as produced by shaded relief. An attempt is made to describe map reading in its two major steps: 1) the enrichment of the brain image resulting from scanning the map sheet,…

Definitions and specific breakdowns of four (auditory reception, visual sequential memory, verbal expression, and auditory closure) of the 12 language areas of the new Illinois Test of Psycholinguistic Abilities (ITPA) are presented. Auditory reception is defined as the ability to understand the meaning of materials or stimuli that are heard and…

Ten test films were developed to measure aspects of children's visual perception which are difficult to assess through conventional paper and pencil tests. The film medium was selected because it allows the presentation of temporal, as well as spacial, aspects of the stimuli. Four areas of perceptual performance covered in the films are: (1)…

The report summarizes the aims of a 3-year program of work concerned with psychological factors in solar observing. Part I identifies several psychological factors which may affect solar observing and outlines a program of research. Part II is a report of a program of studies dealing with the application of visual perceptions in solar flare…

EFFECTS OF TONAL MEMORY OF TWO KINDS OF FACTORS WERE STUDIED. THE FACTORS WERE (1) THE CHARACTERISTICS OF STIMULI PRESENTED TO THE SUBJECT IN A PITCH IDENTIFICATION TASK, AND (2) THOSE EFFECTING THE RESPONSE THAT THE SUBJECT MAKES IN SUCH A TASK. FIVE HYPOTHESES WERE ADVANCED FOR STUDY. THE UNDERLYING ASSUMPTION WAS THAT THERE ARE IMPORTANT…

The purpose of the present work was to investigate the relation between pattern goodness and accuracy of reproduction in backward masking. It may be hypothesized that good patterns, being easier to encode as wholes, will be reproduced more easily than poorer patterns. Four experiments were performed. (Author)

Three groups of Nigerian high school and college students were tested for response to four pictorial depth cues. Students had more difficulty with cues concerning the relative size of objects and the foreshortening of straight lines than with cues involving overlap of lines and distortion of the angles between lines.

Outlines two competing hypotheses concerning the nature of inter-modal sensory development. Research on auditory-visual coordination in young human infants is reviewed. It is concluded that the data support the notion of ontogenetic development being a process of intergration between sensory systems that are initially relatively independent.…

The objective of this study was to test the cognitive identity of older male and female populations with reference to raw score, component structure, and component score measures of spatial and verbal performance. Women (N=100) and 96 men were administered three verbal and six nonverbal cognitive subtests. (Author)

Investigated with 125 children (4-14 years old) with speech, language, or emotional disorders was the assumption that the naming function can be underdeveloped because of defects in the word's gnostic base. (Author/DB)

This paper presents a model of infant visual recognition which proposes that an infant faced with a novel and a previously exposed target responds with one "look" consisting of a chain of 2 covert responses: (1) an attentional observing response to a dimension and (2) a fixation response to a cue. (Author/JMB)

A series of experiments is described whose aim was to define certain of the effective dimensions of stimulation in the newborn's visual environment. (Author/JMB)

Presents the results of investigating mature readers' focal points when viewing letters, words, and phrases. Several hypotheses from the experiments imply subconscious preprocessing for the mature reader. (JM)

Two experiments investigated children's tendencies to draw what they know rather than what they see. The first experiment looked at the way children, aged five to nine, and adults represent an object occluded by another object. Most subjects drew only what they could see. The second experiment investigated subjects' interpretation of pictures…
