Feedback and Skill Learning

Abstract

This study was an investigation of the course of learning a specified arm movement pattern under conditions that varied as to the type and frequency of feedback information. After several days of practice, subjects performed a criterion test which was the same as the learning movement pattern, but explicit visual feedback was withdrawn.

Forty undergraduate students were divided into five groups. Each group was randomly assigned a method of learning the task. The methods of receiving information about performance were as follows: (a) concurrent visual feedback, (b) concurrent proprioceptive feedback and terminal knowledge of graphs, (c) a combination of (a) and (b), (d) concurrent visual feedback interspersed with passive watching, and (e) concurrent visual feedback at two different speeds.

The results indicated the following: (a) the most effective variable for learning the pattern was concurrent visual feedback, (b) performing the movement at a slower than normal rate was detrimental to performance on the criterion test, (c) sitting and watching was as effective a learning method as performing at two speeds, and (d) subjects in the slow-standard speed group were significantly poorer than subjects in other groups during performance of the criterion test. The other methods did not differ significantly from each other.

Social-emotional adaptation and infant-mother attachment in siblings: role of the mother in cross-sibling consistency

We investigated concordance in social-emotional behavior and attachment of first- and secondborn siblings from 65 families. Both children were seen at 24 months in a problem-solving procedure and at 12 months in the Strange Situation. Maternal behavior at 24 months also was examined. Child behaviors at 24 months showed trends toward concordance across siblings. Maternal behavior was significantly stable across siblings and correlated significantly with child competence. In post-hoc analyses, the sample was split into 2 groups: maternal behavior stable (N = 36) and maternal behavior unstable. In the first group, cross-sibling correlations were significant and larger than for the whole sample; in the second group, cross-sibling correlations were low and nonsignificant. There also was significant concordance across siblings in attachment classification. These data suggest that it is essential to consider the care received by different children in investigating similarities in siblings' behavior.
