Stimulus Control
Prior conditioning: US is the only one that doesn’t require prior
conditioning. Even a stimulus that you barely notice can gain stimulus
control if there has been enough conditioning. All other stimuli would
need prior conditioning to affect behavior. Prior conditioning can make
even small stimuli gain stimuli control and they can reliably affect
behavior. i.e. whispering “sit” and dog heard it from other side of the
house and runs over in excitement. i.e.2.opening the cheese door in the
fridge. So saying sit, if the dog sits, it sets the occasion for the dog to do
the behavior of sitting. Is a CS and S^d for sitting. Because she became
excited it will stick to the cue the word sit. So with prior conditioning
you’ve created stimulus control in these says: CS or S^d.
Salience of the stimulus: with a lot of conditioning even non salient
stimulus can gain stimulus control the salient stimuli are most likely to
gain stimulus control (bigger, brighter, louder, closer stimuli).
Other stimuli can facilitate or compete: presence of other stimuli in the
environment which can stimulate or compete with the stimuli you are
trying to get to gain control. i.e. if squirrel runs by they might not listen if
you call her to come back, or if you only got your dog at age 3 they might
not listen as well as if you had from birthday.
You don’t need to be consciously aware of a stimulus for it to gain
stimulus control. i.e. advertising, smell of fresh baked cookies in an open
house then not knowing why you loved that house so much.
So in stimulus control stimuli can facilitate or compete.
Generalization (OC)
In OC and CC you can get generalization and discrimination in both. In
generation you get conditioned to one particular cue, you have OC, stimulus
becomes SD which sets the behavior for a behavior to happen. The cue
becomes the S^d but you can a lot respond to similar cues. Sit becomes
cue/S^d but dog can also respond to words that sound similar to the word sit
(“psych”). Depends on how similar your similar is to the original S^D, or non
how similar the environment is in which the behavior was learned originally.
i.e. dog failing to generalize where do to the behavior. Only knows to sit if
told in kitchen. So in generalization you get stimuli which are similar yet
different than the original S^D which set he occasion for the original
behavior. Similarity to the original environment in which the behavior was
learned/similarity to original SD. (The probability of responding: increases
with similarity of environment, and decreases the more the environment
differs from the original one?) Original context/SD is where you learned the
behavior. This is called the generalization gradient: the further away you are
from the original environment, the less likely you are to respond. i.e.
practicing prosocial behaviors in class room versus in public.
Undergeneralized: if prosocial behavior was only in original place, and once
