Topic 4 (Learning) Flashcards
What theory is the foundation of the behaviourist perspective?
Learning theory
What is prediction?
Predicting the future from past experience, and using these predictions to guide behaviour.
What is a reflex?
A reflex is a behaviour that is elicited automatically by an environmental stimulus.
What is habituation?
Refers to the decreasing strength of a reflex response after repeated presentations of the stimulus.
What three assumptions do theories of learning share?
- Experience shapes behaviour.
- Learning is adaptive
- Careful experimentation can uncover laws of learning
What are the laws of association?
Law of contiguity, law of similarity, and law of contrast.
What does associationism believe?
That complex thoughts are nothing but elementary perceptions that become associated and then recombined in the mind.
What is the law of contiguity?
Two events will become connected in the mind if they are experienced close together in time (such as thunder and lightning).
What is the law of similarity?
The law of similarity states that objects that resemble each other (such as two people with similar faces) are likely to become associated.
What is classical conditioning?
Occurs when we learn to identify a relationship between two different stimuli.
Learning where an environmental stimulus produces a response.
What is an unconditioned reflex?
A reflex that occurs naturally, without any prior learning.
What kind of stimulus produces an unconditioned reflex?
Unconditioned stimulus.
What is a UCR?
An unconditioned response (UCR) is a response that does not have to be learned.
What is a CR?
A conditioned response (CR) is a response that has been learned.
What is a CS?
A conditioned stimulus (CS) is a stimulus that, through learning, has come to evoke a conditioned response CR.
What is the initial stage of learning in which the CR becomes associated with the CS?
Acquisition
What is a conditioned emotional response?
Neutral stimulus is paired with a stimulus that evokes an emotional response (Little Albert).
What is one explanation for phobias?
Classical conditioning. Fears are acquired through subcortical pathways (activated before cortex even gets the message).
What is psychoneuroimmunology?
The study of the interaction between psychological processes and the nervous and immune systems of the body.
What is a conditioned immune response?
CS is paired with a stimulus that evokes a change in the functioning of the immune system.
What is stimulus generalisation?
Responding similarly to stimuli that resemble the CS.
What is stimulus discrimination?
Learned tendency to respond to a restricted range of stimuli used during training.
What is extinction?
Weakening of CR by presenting CS without UCS.
What is a conditioning trial?
Each pairing of the CS and UCS is known as a conditioning trial.
What is spontaneous recovery?
The re-emergence of a previously extinguished CR.
What factors influence classical conditioning?
Interstimulus interval (time between), individual’s learning history, prepared learning.
What is the optimal interval?
The optimal interval between the CS and UCS is very brief, usually a few seconds or less.
What is maximal conditioning?
Maximal conditioning occurs when the CS precedes the UCS.
What is forward conditioning?
- delayed conditioning (forward) - the CS is presented before the US and it (CS) stays on until the US is presented. This is generally the best, especially when the delay is short. example - a bell begins to ring and continues to ring until food is presented.
What is simultaneous conditioning?
The CS is presented at the SAME TIME as the UCS.
What is backward conditioning?
The CS is presented AFTER the onset of the UCS.
Why is an extinguished response easier to learn the second time around?
Later learning can build on old ‘tracks’ that have been covered up but not obliterated. Neuronal connections established through learning may diminish in strength when the environment no longer supports them, but they do not entirely disappear.
What is blocking?
The failure of a stimulus to elicit a CR when it is combined with another stimulus that already elicits the response.
What is latent inhibition?
A familiar stimulus takes longer to acquire meaning.
What is prepared learning?
The biologically wired readiness to learn some associations more easily than others.
