Chapter 4 - Basic Phenomena Flashcards
Extinction
CS becomes less strong bc it occurs without US
Acquisition
Strengthening a classically conditioned response
Spontaneous recovery
Reappearance of CR to CS of following rest period after extinction
Disinhibition
Sudden recovery of response during extinction when a novel stimulus is introduced
Higher order conditioning
A stimulus is associated with a CS an becomes a CS but is weaker than original.
Higher order conditioning wasp example
Get stung by a wasp. See wasps around your neighborhood trash can, the trash cans elicit a form of discomfort now as well.
Sensory preconditioning
A stimulus has been conditioned and a perviously presented stimulus is now conditioned even if it wasn’t directly paired
Sensory preconditioning wasp example
You have a acquired a fear of wasps due to being stung. You remember that a wasp nests was in a toolshed once and are now scared of the wasps.
Overshadowing
Most salient member of compound stimulus is more readily conditioned
Overshadowing basketball example
You and someone else are the best of the best of basketball. He is more likely to overshadow you Bc he looks more salient or more fit to be a basketball player
Blocking
Presence of an established CS interferes with the conditioning of anew CS
Blocking dog/light example
Light paired with food = salivation
Light + tone with food = salivation
Tone with food = no salivation
Light blocks tone, no conditioning happening
Latent inhibition
Conditioning of an unfamiliar stimuli is more easily than a familiar one
Latent inhibition dog/tone example
Dog heard tone 40 times.
Tone is paired with food once.
Dog doesn’t salivate to only tone
Temporal conditioning
CS is a passage of time (dog give food every 10 minutes, begins to salivate towards the end of 10 minute interval)
Temporal conditioning bomb example
City is bombed for several nights in a row at 2 am, people will begin to feel anxious as 2 am approaches
External inhibition
Opposite of disinhibition. Decrease in CR due to presentation of novel stimulus at the same time as CS
External inhibition wasp example
Wasps are buzzing around, you feel anxious but a violinist begins to play and distracts you which decreases your anxiety
US revaluation
Post conditioning presentation of US at a diff level of intensity thereby altering the strength of response
US revaluation dog example
Bell paired with small amount of food = small salivation. Then given a large amount later = large salivation. Bell = large salivation (revalues amount, expects more)
Pseudoconditioning
Response occurs due to sensitization rather than conditioning
Pseudo conditioning war example
Shots fired scares a soldier. Now any sudden change scares him such as door slamming or tap on shoulder
