Lab 5 Flashcards
Classical conditioning
is a type of learning where a neutral stimulus becomes associated with an unconditioned stimulus (US) to produce a conditioned response (CR) and a conditioned stimulus. This concept was famously demonstrated by Ivan Pavlov with dogs, but it can be applied in many other contexts.
Stimulus and response in sniffy
Neutral stimulus: Sound
Unconditioned stimulus: Food
Unconditioned response: Sniffy’s behaviour
Conditioned response: Continuity of the behaviour to get more food
Conditioned stimulus: Sound + food
Magazine training
Magazine training is a technique used in animal behavior training, particularly in operant conditioning, where the animal is trained to associate a sound (usually a click or a “magazine” sound) with a reward, typically food.
What is a secondary reinforcer
a stimulus or object that acquires its reinforcing power through association with a primary reinforcer. In other words, a secondary reinforcer does not inherently satisfy a biological need (like food or water), but it becomes reinforcing because it has been linked with something that does.
Shaping bar pressing
involves reinforcing successive approximations of the rat’s behavior, gradually guiding it toward the desired action (pressing the lever). Through this process, the rat learns the behavior step by step, with each action becoming closer to the final behavior.
Cumulative record
Tracking sniffy’s bar pressing on a printer like apparatus
Extinction of bar pressing
When the behaviour no longer produces any reward
Spontaneous recovery
Reappearance of the behaviour after extinction
IV, DV, CV
IV: Before vs after training procedures ( A pre test - post test design)
DV: Rate of bar pressing behaviour (bar presses per minute)
CV: Animal is motivated to find food (always hungry)
Every bar press gets rewarded (continuous reinforcement)
Experimental design
What is the effect of shaping procedures on sniffy’s bar pressing rate
