The proposition was investigated that concept learning is a twofold process: acquisition of a prototype and development of generalization and discrimination skills. The assumption that formative evaluation procedures are necessary when attempting to prepare better instructional treatments for improved student performance was tested. (Author/GK)

If the classroom English teacher is to be given any assistance in determining the most appropriate literary experiences for developing students' literature appreciation, it is imperative that research create a clearer understanding of the factors involved in developing discrimination in literature.

Subjects were trained against their initial dimensional preference in a two-dimensional simultaneous discrimination learning task. (RH)

A study investigating the discrimination abilities of two crib-bound, cerebral palsied, profoundly retarded females demonstrates the importance of individual differences among such children and suggests that discriminative responding may be demonstrated by at least some profoundly retarded children, particularly if distributed practice is employed…

Reports three experiments to investigate differences in the semantic classification of pictures and words. The data suggest that visual short-term memory and semantic memory operate in semantic-decision tasks though these sources of information differ in characteristics, potential for activation, and level of abstraction.

A total of 540 college students were run in two verbal discrimination learning studies (the second, a replication of the first) with one of three verbal reward conditions. In both studies, equal numbers of male and female subjects were run in each reward condition by each male and female experimenter. (MS)

Investigates the prediction that the usual superiority of pictures over words for repetitions of the same items would disappear for items that were different instances of repeated categories. (Author/RK)

Four experiments investigated newborns' ability to discriminate, recognize, and learn visual information embedded in the schematic face-like patterns preferred at birth. Results indicated that newborns discriminated face-like stimuli relying on their internal features and recognized a perceptual invariance between face-like configurations in…
