topic 3 (midterm 2) Flashcards
latency of conditioned response
the interval of time between presentation of the Conditioned stimulus and occurrence of the Conditioned response
intensity of the conditioned response
conditioned responses tend to get stronger as conditioning proceeds
test or probe trials
present the conditioned stimulus alone ( without unconditioned stimulus). Whether or not repones still occurs, serves as evidence for learning.
higher order conditioning
where a previously established conditioned stimulus, is used to condition a new neutral stimulus.
factors influencing conditioning
-nature of NS and US (intensity and belongingness)
-contingency between NS and US
-Previous exposure to NS
-Temporal relationship of NS and US
-number of pairings
stimulus features
physical characteristics effect the pace of conditioning
overshadowing
when a compound stimuli is used as a CS, but only a particular element of that compound is able to elicit a CR
short delay conditioning
Conditioned stimulus is presented alone, but unconditioned stimulus overlaps shortly after onset. Usually most effective conditioning procedure
long delay conditioning
conditioned stimulus and unconditioned stimulus overlap, but conditioned stimulus is on for longer time.
trace conditioning
no overlap between conditioned stimulus and unconditioned stimulus. Conditioned stimulus is presented first.
simultaneous conditioning
conditioned stimulus and unconditioned stimulus onset is at the same time.
backward conditioning
unconditioned stimulus occurs before the conditioned stimulus
intertrial interval
interval between 1 CS-US exposure (trial) NS and another CS-US exposure (another trial)
contingency between NS and US
this means that the NS and US co-occur reliably (i.e. one does not occur without the other)
contiguity
events are close together in time and in space
latent inhibition
pre-exposure of a stimulus in the absence of a US interferes with the ability of that stimulus to become a CS
blocking
failure of a stimulus to become a CS when it is part of a compound stimulus that includes an already effective CS
sensory preconditioning
- two neutral stimuli (A & B occur together)
- one of those stimuli (B) becomes a CS
- When A is presented alone , it elicits same response as B
