N iemelá , P. Heart rate responses during anticipation of an electric shock of variable probability. Scand. J. Psychol ., 1969, 10 , 232 ‐242.—Lacey's model associating heart rate deceleration with attention and acceleration with mental activity was tested. Subject concentrated on a figure indicating probability of receiving an electric shock after 20 seconds. Deceleration was predicted when shock positively would or would not come. Acceleration followed by deceleration was predicted for subjects anticipating 0.50 probability of shock since the beginning of anticipation would demand assessment of the situation. The hypotheses were supported by the data excluding the last trials. Electrodermal reactivity was linearly related to shock probability.
