In order to investigate the relative effectiveness of specific media attributes on student performance on criterion tests, a comparison was made of the effectiveness of two levels of stimulus explicitness in visuals in facilitating student achievement on criterion tests of knowledge, comprehension, and total understanding. Subjects were 171…

One week later, a recognition test was given in which ability to remember elaborated and unelaborated pictures…

Human neonates selectively fixated patterns with curved rather than straight contours when the outermost contours differed in this form variable and when quantitative variables were controlled. Data indicated the presence from birth of a discrimination ability basic to later form perception. (Author/ED)
