Observation and shaping learning: A comparison using Long Evans rats

Abstract

The acquisition of a lever-press response was compared between groups of hooded rats who learned through observation or shaping. The trials-to-criterion data revealed that the observation and shaping techniques did not differ from each other, but that they were superior to the control procedures. Analysis of total number of lever presses demonstrated that the observation technique was superior to the shaping technique and that the shaping technique was superior to the controls. These results are contrary to recent reports, presumably because the present investigation employed a series of procedures to optimize the visual process. © 1969, Psychonomic Journals, Inc..
