The Equation of the Galvanic Skin Reflex Curve: I. The Dynamics of Reaction in Relation to Excitation-Background

Previous studies of double alternation learning have failed to demonstrate learning of extended double alternation sequences by nonprimate Ss. The present study investigates whether such learning can be induced by manipulations of the training procedure. Pigeons (N = 6) were trained on a double alternation procedure with continuous trial presentations. A new double alternation sequence began after each error so that the length of a sequence was a function of the accuracy of performance. All Ss learned the double alternation pattern for the first four positions of the sequence, but none learned consistently to emit longer sequences. The degree of learning was a function of several procedural variables, particularly the use of an appropriate correction procedure.
