Timing of the stimulus for Operant Conditioning?

[julie9300]

My textbook says that the stimulus comes before the response, so it's referring to the discriminative stimulus. But some notes that I got from a lecture said that the stimulus comes after the response, so I'm assuming the stimulus in this case is the reinforcement.

I'm kinda confused, does timing of the stimulus refer to the reinforcement or the discriminative stimulus?

Oh and my textbook is the Oxford one, and I'm wondering what the Grivas book says

"Stimulus" should refer only to the discriminative stimulus, and it always comes before the response. Reinforcement or punishment is the consequence, not the stimulus 

"Timing of the stimulus and response" is a bit confusing

In classical conditioning, they're essentially saying that presentation of a conditioned stimulus produces a conditioned response, and that during acquisition, the neutral and unconditioned stimuli must be paired very closely (eg. about half a second apart).

In operant conditioning, they're saying that a particular behaviour acts on the environment and is followed by some sort of consequence, whether that be reinforcement or punishment. Also, although the time period between pairing of a response and its consequence is important, especially in lower-order mammals, it is less important than in classical conditioning

Btw, Grivas doesn't really mention anything about discriminative stimuli, but VCAA do expect you to know about it

Thank you!
