This study supported by a Public Health Service Research Grant, establishes "that discrimination reversal learning and transposition can be markedly facilitated by a common training procedure which is essentially perceptual in nature. (Author)

Twenty-seven 4-month-old infants heard a repetitive auditory rhythm, then viewed silent film of puppet opening/closing its mouth, either in the familiar rhythm or a novel rhythm. Results showed infants exposed to the novel condition watched the film longer than infants shown the familiar condition, providing evidence for auditory-visual transfer…

Immediate discriminative control by spoken words was examined in a profoundly retarded, mute young man. Procedures suggested a potentially errorless, efficient teaching method for individuals without fundamental language. (Author/SB)

Clarifies the differences between two meanings of discrimination: (1) the process of differentiating between objects and (2) making choices with a bias against a particular choice. The author argues that the two meanings are often confused in education, and that unbiased discrimination to establish personal preferences is morally justifiable. (AM)

Determines whether an averaged evoked potential technique using a random-v-repetitive presentation mode could be used to study infant auditory discrimination. Results showed a main effect of presentation mode with shorter latency for random v repetitive. The shortest onset latency was for random stimulus at the fast rate. (Author/DB)

Focuses on auditory fusion (defined in terms of a listerner's ability to distinguish paired acoustic events from single acoustic events) in 3- to 12-year-old children. The subjects listened to 270 pairs of tones controlled for frequency, intensity, and duration. (CM)

One hundred and sixty subjects from five age levels ranging from 3 to 20 years compared photographs of dogs (e.g., two different Great Danes or a Great Dane and a Doberman pinscher) and judged whether they were similar or different. (Author/MP)

Responsivity to graded tactile stimuli was examined in human newborns in successive epochs of active and quiet sleep. Heart rate and behavior were both used as response indices. (Author/SS)

Three experiments examined the effect of different kinds of background features on children's orientation discrimination. A fourth experiment tested the hypothesis that errors in discrimination of obliques can be attributed mainly to confusion over the left-right direction of tilt. Subjects were 160 five-year-old and 20 seven-year-old children.…

In a recently reported study, the functional components of imagery and vocalization strategies in children's verbal discrimination learning were examined, following the combined experimental/correlational logic of Underwood. The present research extends those results to a strategy that (unlike imagery and vocalization) has a positive influence on…

It is pointed out that interpretation of learning set data will be easier and more informative if one uses a "first-order" problem, that is, one which can be solved on the first trial at the end of training. (Editor)

This study examined the relationship between syntax discrimination and other language skills with 50 children each in kindergarten, first grade and second grade. Also, the children were asked to imitate and show comprehension of normal and scrambled grammar sentences. (Author/JH)
