Abstract In each of the two experiments, nine rats were trained for 64 trials (eight trials per day) to determine if they could acquire a two‐choice discrimination based on a specified discriminative stimulus (S D ). In one experiment, the S D was a change in ambient illumination, while in the second experiment the S D was a change in the combination of sinusoidal 60 Hz and static magnetic field (MF) and any cues attendant to energizing the coils that produced the MF exposure. The rats that had a change in illuminance as the S D learned the two‐choice task easily, P < .001, whereas the rats having a change in MFs as the S D did not.
