Document Summary
What makes effective conditioned and unconditioned stimuli: novelty. The more novel stimuli are, the more likely conditioning is to happen, and the quicker it will happen: due to habituation. Latent inhibition effect: repeated presentation of the cs by itself, same cs is presented with us using classical conditioning, the pairing is slower, overinclusiveness. Have a lot more in their perception; not incredibly focused. Tend to do better on latent inhibition tasks. Quicker to figure out that the previously ignored stimuli is helping them; less likely to habituate in the first place.

A bell is paired with food: pairing is slower. Because the ringing of the bell had been ignored due to habituation: intensity. The more intense the stimulus, the more vigorous the response.
