Effects of delayed reward on simultaneous and successive discrimination learning in children.

Abstract
Groups of 4th-grade children were given 54 trials with either a simultaneous presentation of 3 different colored lights or the presentation on each trial of 3 lights of the same color, and with either a 0-, 3-, or 6-sec. delay of reinforcement. Correct response consisted of pushing the button beneath the "correct" light in the simultaneous situation, or pushing the button in a position determined by the color of the lights in the successive situation. The effect of delay was not significant. The interaction between trials and type of discrimination was significant, suggesting that the simultaneous group had a greater learning rate in accordance with Spence's discrimination learning theory.
