Abstract
Ss predicted whether a red light or a white light would flash after a ready signal. Under neutral conditions Ss approximated the actual percentage of red lights in 100 trials. “Red” predictions were suppressed significantly when onset of the red light was accompanied by electric shock. Continuous and intermittent shock-light pairing were equally effective in lowering prediction rate.
