Quizplus · Accepted Answer

The stage in which the flatworm's contraction response to light is first established and gradually strengthened is called acquisition. This occurs as the light is repeatedly paired with electric shock, causing the flatworm to learn to associate the light with the shock and therefore learn to contract its body in response to the light. Discrimination refers to the ability to distinguish between different stimuli, generalization refers to the extension of a learned response to similar stimuli, and spontaneous recovery refers to the reappearance of a previously extinguished response after a period of time.
