Response
Latency Change as a Measure of Blocking in Children
R.A. Lyczak |
Blocking
of stimulus control was studied in a simultaneous discrimination
task. During Phase I of the experiment, stimulus Dimension A was
relevant to solution for Experimentals and stimulus Dimension C for
Controls; during Phase II, Dimensions A and B were redundant and
relevant for both Groups; during Phase III, both Groups received
unreinforced test trials on Dimension B. In Experiment 1, Experimental
subjects demonstrated significantly greater increases in response
latency during Phase III than Controls. In Experiment 2, Experimental
subjects demonstrated greater increases when testing on B followed
immediately after Phase II, but not when test trials on A preceded
testing on B.
