what did IVan Petrovich Pavlov’s experiment
demonstrates the effect of conditioning on dog salivation
How did Pavlov investigate and why
investigated the digestive system of dogs by presenting them with meat powder and measuring the amount of saliva produced
What was the conclusion of Pavlovs experiment
the dog began to salivate even before the meat powder was presented as they associated the feeder with the meat powder. This led Pavlov to conclude that the dogs were conditioned to respond to the feeder through the process of classical conditioning.
Classical Conditioning
a type of learning involving the association from one object to another object that does not have relation to it only by conditioned response
What was an unethical experiment
Scientists Watson and Raynor made a baby fear white fluffy things by doing a loud noise and showing a rat.
Neutral Stimulus NS
stimulus prior to conditioning that does not produce a response this is the one that turns into a conditioned stimulus
Unconditioned Stimulus UCS
A stimulus that innately produce a response or reflex
what is an example of neutral stimulus
pavlovs bell in his experiment
what is an example of unconditioned stimulus
the meat in Pavlov’s experiment
unconditioned response UCR
an unlearned response by an unconditioned stimulus
ASSOCIATION
a connection between two events which results in learning
What is an example of association
the dog associated the bell with food and would salivate
Conditioned Stimulus (CS)
after neutral stimulus is paired with unconditioned stimulus many times the neutral stimulus becomes the conditioned stimulus
what is an exampled of conditioned stimulus
the bell it now elicits a learned response
conditioned response
a learned response to a conditioned stimulus
what is an example of conditioned response
the dog learned to salivate at the bell
what is another word for conditioning
learning
what does unconditioned mean
unlearned or before the learning process takes place
What are the main elements of classical conditioning
extinction
Stimulus Generalization
stimulus discrimination
spontaneous recovery
what does extinction mean?
a conditioned response that is no longer reinforced but unconditioned stimulus the condition response no longer occurs
What does stimulus generalization mean
when an organism has been conditioned to respond to a stimulus, it will often respond to similar stimuli.
what is stimulus discrimination
when an organism has been conditioned to respond to a stimulus, it will often respond to similar stimuli.
spontaneous recovery
The reappearance of a conditioned response after extinction and a rest period
operant response
A response or behavior of an organism that is voluntary and not associated with a particular stimulus.
what does the response of operant response act on or modfies?
the enviroment
whats an example of operant response
person picking up a book to read
what is reinforcer
The reward given for the response in order to strengthen it and increase the likelihood of the response occurring again
f
what is positive reinforcer
A reward which strengthens a response by providing a pleasurable consequence such as praise or chocolate bar
what is negative reinforcer
A reward which strengthens a response by removing or reducing an unpleasant stimulus such as takin away a chore or homework
what is schedule of reinforcment?
The frequency in which a response is reinforced in operant conditioning.
what is continuous reinforcement
when a satisfying response is reinforced every time.
what is partial reinforcement
reinforcement which does not occur continuously. The reinforcement may be administered in the following ways:
what is fixed ration schedule
a satisfying response is reinforced after a set number of responses have been made, e.g. every fifth response.
what is fixed nterval schedule
a satisfying response is reinforced at regular time intervals e.g. every five minutes.
what is variable ratio schedule
a satisfying response is reinforced at random intervals within a fixed length of time e.g. catching four fish within a two-hour period
