Summary
Forty-two Ss were run in one experimental and in two control conditions. The Ss recalled a short story immediately after reading it and again 24 hours later. All Ss were monitored on two physiological variables during reading. The experimental group was subjected to a 0.2-second delayed auditory feedback in the middle section of the story. One control group received no special treatment; the other received shock at the point in the story at which the experimental group received delayed auditory feedback. Both the experimental group and the control group that received shock showed marked changes in GSR measurements during the reading of the middle section of the story. The immediate memory of the story was significantly poorer for the experimental group as contrasted with that for each of the control groups. For accuracy of delayed memory, there were no significant differences among the three groups.
