adequate stimulus

the type of stimulus for which a given sensory organ is particularly adapted. Thus, the adequate stimulus for the eye is photic (light) energy. Although mechanical pressure on the eye or an electrical shock can stimulate the retina and produce sensations of light, these are not adequate stimuli for the eye.
