DISCRIMINATION LEARNING AND DISCRIMINATION LEARNING SETS IN SUBNORMAL CHILDREN*

British Journal of Educational Psychology, 1967
Summary. The aim of the enquiry was to establish whether subnormal children have more difficulty than normals of comparable mental age in learning a visual discrimination and in forming a discrimination set. Twenty‐eight older sub‐normal children and twenty‐four normal pre‐school children were required to solve six visual discrimination problems ...

Discriminant Learning Analysis

IEEE Transactions on Systems, Man, and Cybernetics, Part B (Cybernetics), 2008
Linear discriminant analysis (LDA) as a dimension reduction method is widely used in classification such as face recognition. However, it suffers from the small sample size (SSS) problem when data dimensionality is greater than the sample size, as in images where features are high dimensional and correlated. In this paper, we propose to address the SSS

Discrimination Learning

Science, 1959
Eight rats were run through discrimination training sessions in which responses in the dark were not reinforced whereas the first response after the onset of a light was reinforced. The procedure generated orderly learning and latency data for the individual animal. The latency distributions are adequately described by a simple mathematical formulation.

Discrimination Learning and Inhibition

Science, 1966
Pigeons learned to discriminate between a white vertical line on a dark background (S+) and a monochromatic circle of light (S—) either with or without responses to S— (errors). Gradients of inhibition, which were centered around S—, and which had greater than zero slopes, were obtained only from those subjects who learned to discriminate with errors ...

Transfer in Discrimination Learning

Child Development, 1965
Two types of pretraining preceded testing on the oddity problem for 4- and 6-year-old children and on the conditional-oddity problem for 9- and 12-year-old children. It was found that age factors were important determiners of transfer in both situations.

Frequency discrimination learning in children

The Journal of the Acoustical Society of America, 2008
Psychoacoustic thresholds of pure tone frequency discrimination (FD) in children are elevated relative to those of adults. It has been shown that it is possible to improve FD thresholds in adults, following a single (subhour) training session. To determine whether FD thresholds in children may be improved by training and, consequently, reduced to adult

Discrimination Pretraining and Sound Learning

Perceptual and Motor Skills, 1965
Sound production learning as a function of sound discrimination learning was investigated. First grade Ss who were observed to utter /skrə'b/ for /srə'b/ were assigned to two discrimination pretraining groups ( N = 15 in each group): Group A, discrimination training on /skrə'b/-/srə'b/ and Group B, discrimination training on /sliyp/-/∫liyp/.

Discrimination reversal learning in the crayfish

Animal Behaviour, 1967
Summary Nine crayfish failed to show progressive improvement in learning over nine reversals in a two-choice spatial discrimination problem involving a non-correction procedure of training. The results are discussed in their relationship to the habit reversal data on other species.

Discrimination Learning Set in Children

1964
Publisher Summary This chapter reviews part of the literature on discrimination learning set. It is limited to one general topic-the nature of learning set-and one research topic— “response shift”—which is theoretically important and has received considerable attention in the research literature.
