|
Unconditioned Stimulus (US) |
Stimulus that elicits the reflex bx ex. Food (US) elicits salvation. |
|
|
Unconditioned Response (UR)
|
Response to the US or reflex bx ex. Salvation (UR) occurs when you see food (US) |
|
|
Conditioned Stimulus (CS) |
Neutral stimulus; doesn't elicit any bx ex. Bell doesn't elicit salvation, but may be learned |
|
|
Conditioned Response (CR) |
Response to CS |
|
|
Fear Conditioning |
Conditioned Emotional Response (CER) ex. Tone----->Shock So, Tone----->Fear FEAR CONDITIONING IS EXCITATORY! |
|
|
Measuring fear (2 ways) |
-Directly measure -Suppression of behavior |
|
|
Suppression Ratio |
(CS responding) (CS responding) + (pre CS responding) -suppression rate is on a range from 0-0.5 -if suppression rate is near 0.5, not much suppression occurred aka no learning of fear(crappy learning) -if suppression rate is near 0, a lot of suppression occurred aka complete conditioning of fear(great learning) |
|
|
Excitatory |
-will increase your CR over time -presenting CS will be paired with US
ex. tone---->food |
|
|
Inhibitatory |
-will decrease your CR over time -CS followed by no US ex. Tone---->no food |
|
|
Examples of Excitatory (4) |
-Eye blinking conditioning -Fear conditioning -Taste aversion -Autoshaping/sign tracking |
|
|
Eye Blinking Conditioning |
|
|
|
Autoshaping/Sign Tracking |
Animals approach & touch cues that signal availability of something they want (ex food) -animal feels sense of belongingness |
|
|
Taste Aversion |
Learned if ingestion of a novel flavor is followed by an aversive consequence such as food poisoning or indigetion 2 special features: -one-trial learning (only takes 1 time to learn) -long-delay learning (may take a couple hours etc to feel sick) |
