The present experiment examined the choice behavior of humans during the learning of a reversal (R) shift as an empirical test of attentional explanations of the overtraining reversal effect. (Author/RK)

Second-grade children were trained on an optional shift task in order to assess the relation between the amount of overtraining and (a) the type of shift executed by Ss, and (b) the breadth of learning. (Editor)

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.

This paper presents further data on the Moss-Harlow Effect, together with some new theory, supporting the conclusion that younger subjects prefer novelty more than do older children. (Author)

Results revealed that (1) relevant verbal experience facilitated learning only for preschoolers, (2) irrelevant verbal experience did not interfere with learning, and (3) visual highlighting exerted no significant effects. (Author/MB)

This experimental study has three aims: (1) to give a detailed description of imitative behavior as it develops during the first six months of life; (2) to compare imitative responses perceived through visual, kinesthetic and auditory modalities; and (3) to describe and explain the regulating mechanisms and processes present in the early…
