Eighty-four nine year old children, twelve in each of seven experimental groups, learned a two-choice successive discrimination problem. The parameters that were systematically manipulated included: (1) immediate versus delayed reinforcement; and (2) forced preresponse stimulus exposure versus stimulus exposure during the delay interval,…

Investigates the ability of secondary school students to discriminate causal explanations from teleological and anthropomorphic explanations (TAE), and explains that a significant improvement in this ability can be achieved by appropriate teaching procedures in a relatively short time. (Author/GA)

The attention hypothesis of Zeaman and House is examined through a systematic, computer-simulation analysis of the parameter interactions found in One-Look model. (Author/SB)

Describes an experimental study which investigated the relative efficacy of two types of concept nonexamples in preventing overgeneralization errors among first grade students (n=67). Results indicated that the group which received both coordinate and ordinary concept nonexamples scored significantly higher than the group which received only…

The study found that providing feedback and goals in an accelerating standards condition had a positive effect on the learning of eight retarded children (mean age 9 years) on a five-choice discrimination task requiring vocabulary and perceptual competence. (Author/DB)

This study tested the hypothesis that the reported increase in children's use of prepositional phrases when exposed to novel (inverted) prepositional phrases could be eliminated by discrimination training in two prepositional forms. (Author/MS)

The present paper reports the results of four experiments on verbal discrimination learning. These experiments manipulated the associative properties and the language frequency of stimuli, as well as the pairings of "right' and "wrong' items within a list. (Author)

Forty-three severly or profoundly retarded children and adolescents who were presented with a series of three-and 10-trial form discrimination problems learned faster on the first three trials if each problem lasted for ten trials. (Author/MC)

Liniar functions fitted to the proportion of optional reversal shifts as a function of log CA were used to assess the effect of stimulus and training variables on the development of reversal-shift. (ST)

Reports that participants in a perceptual training program at the kindergarten level performed at a higher level than non-participants according to reading, arithmetic, and composite achievement scores obtained in grade three. (TO)

The present study operationally defines selective attention in terms of tactile observing responses measured by percentage contact time per trial to the relevant stimulus dimension, and investigates the changes of these responses in a discrimination shift paradigm under the effect of overlearning.
