Two groups of kindergarten children received stimulus differentiation training either with feedback (experimental Ss) or without (controls), prior to presentation of a series of discrimination-learning problems using blank-trial probes. Findings are discussed in relation to theoretical perspectives derived from Piagetian theory and developmental…

A schema is best understood as a statistically defined concept. Schematic concept formation consists of abstracting the common elements or properties of a defined class in a schema. Thereafter, both discrimination and retention are facilitated, since only deviations from the schema need be processed for any particular class exemplar. In the…

Infants ranging in age from six months to eight months were shown repeated instances of real object movement-disappearance-reappearance. Results suggest that the key changes in early cognitive development rest primarily upon the infant's gradual adaptation of old responses through encounters with new events--rather than upon the acquisition of…

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 paper describes further research on a learning procedure for layered networks of deterministic, neuron-like units, described by Rumelhart et al. The units, the way they are connected, the learning procedure, and the extension to iterative networks are presented. In one experiment, a network learns a set of filters, enabling it to discriminate…

The greater part of this progress report embraces a series of research reports which represent empirical findings during the 1967 academic year. They range from results derived from the first field testing of the college physics, multi-media CAI course, through a series of specific experimental studies focusing on learning and adaptive variables…
