Image size, viewing angle, and contrast affect performance of a visual discrimination task. Further, the three factors interaction in their effect on performance. (Author)

For each work assignment, photojournalists must decide whether to use black-and-white or color film and how to frame the picture. These decisions are considered crucial, yet little is known about how the presence of color and design complexity affect how people process the information in photographs. A study tested whether color and design…

This study examines the effect of an entering behavior, i.e., the level of general knowledge of the subject matter, on the instructional effectiveness of illustrations which integrate abstract and realistic visualization. Subjects were 414 public school students who were divided into three groups according to their general level of knowledge of…

Presents a study designed to investigate the interaction between the cognitive style of field dependence/field independence and ability to recognize ground color change of a visual. A significant difference in recognition scores based on ground color change collapsing across cognitive style is reported. Implications for instructional design are…

The semantic differential ratings of ten typefaces given by a group of 24 subjects were factor analyzed to discover what connotative meanings laypeople applied to typefaces and how these meanings compared with those of professional typographers. The typefaces, five from general categories and five from novelty categories of display typefaces, were…

This experimental study was conducted in an attempt to determine how children--four, seven, and 11 years old--perceive implied motion cues in combination with a variety of objects. Ninety children, 30 in each age group, were shown 24 pictures. There were three kinds of objects, each with an inherent active and static dimension. Each of these six…

This study examined the question of whether the integration of abstract and realistic visualization can improve the effectiveness of visualized instruction. Two methods of integrating visualizations were investigated. The first method used hybrid illustrations, i.e., a real color photograph into which a line drawing segment has been inserted. This…

Discusses the theory and research underlying the use of realistic and compressed images or representational images developed from 1950-80 using print, slides, and film media. Topics include the theories of visual realism, visual realism and instruction, and the foundations of visual compression. (20 references) (KRN)

Since visual discrimination is one of the factors involved in learning from instructional media, the present study was designed (1) to investigate the effects of hue contrast, illuminant intensity, brightness contrast, and viewing distance on the discrimination accuracy of those who see color normally and those who do not, and (2) to investigate…

PRELIMINARY ANALYSES WERE UNDERTAKEN TO DETERMINE THE POTENTIAL CONTRIBUTION OF MOTION PICTURE FILMS TO FACTOR ANALYTIC STUDIES OF HUMAN INTELLECT. OF PRIMARY CONCERN WERE THE OPERATIONS OF COGNITION AND MEMORY, FORMING TWO OF THE FIVE OPERATION COLUMNS OF GUILFORD'S "STRUCTURE OF INTELLECT." THE CORE REFERENCE FOR THE STUDY WAS DEFINED…

The relationship between the perceptual type of adult learners--i.e., visual or haptic--and their performance upon a visual discrimination task was studied to determine if the use of multi-image representations could improve the performance of adults of different perceptual types upon selected visual tasks. Subjects were 135 volunteers from…
