Subjects conditioned concurrently to two different conditioned stimuli, light and tone, exhibited a significantly higher level of conditioning to the stimulus paired with a strong unconditioned stimulus than to the stimulus paired with a weak one. The findings suggest that habit strength in aversive conditioning varies with the intensity of the unconditioned stimulus.
