An experiment was carried out for the purpose of investigating the transfer effects to a motor task resulting from training on one of two types of discrimination required in the learning of that task. The whole motor task required four different manual responses to be made to four light stimuli which could be discriminated on the basis of color red or green and on the basis of position top or bottom. One group of 28 Navy enlisted men undertook 60 learning trials of the motor task without any previous training. Another group, composed of two sub-groups each matched with the control group, learned the task over 60 trials, following 30 trials of practice on two of the responses made to lights differing in color only color discrimination training. A third group, also composed of two sub-groups matched to the control, practiced for 30 trials the responses to two lights differing in position only position discrimination training before learning the whole task. Learning was measured in terms of time required to make a correct response and in terms of numbers of errors. In addition, a record was kept of the number of occurrences of each of the three possible types of incorrect responses. Author
