Unit 3 AOS 2 - How Do People Learn And Remember? Flashcards
Neural Plasticity
Neural plasticity the ability of the brain to physically change in response to experience
Synaptic plasticity
Synaptic plasticity a type of neural plasticity that refers to the ability of synaptic connections
to form, weaken or strengthen in response to activity and experience
long-term Potentiation
Long-term potentiation
the long-lasting and experience- dependent strengthening of synaptic connections
Long term depression
Long-term depression
the long-lasting and experience- dependent weakening of postsynaptic responses
Neurotransmitters
Neurotransmitter a chemical substance that carries information between neurons
Neurohormones
Neurohormone a chemical substance sent from neurons into the bloodstream
Glutamate
Glutamate the primary excitatory neurotransmitter
Adrenaline
Adrenaline (also known as epinephrine) a neurohormone that increases physiological arousal and contributes to the consolidation of emotionally arousing memories
Classical Conditioning
Classical conditioning a model of learning in which organisms learn through the involuntary association of two or more stimuli
Neutral stimulus
Neutral stimulus (NS) a stimulus that does not initially elicit a response
Unconditioned stimulus
Unconditioned stimulus (UCS) a stimulus that elicits a reflexive response
Unconditioned stimulus
Unconditioned response (UCR) a natural (unlearned) behavior to a given stimulus
Conditioned stimulus
Conditioned stimulus (CS) a stimulus that elicits a response due to its being paired with an unconditioned stimulus
Conditioned response
Conditioned response (CR) a response caused by the conditioned stimulus
Aquisition
Acquisition the period of initial learning in classical conditioning in which the learner begins to associate a neutral stimulus with an unconditioned stimulus so that the neutral stimulus will begin to elicit the conditioned response
Extinction
Extinction when the conditioned response no longer occurs for an extended period of time
Spontaneous recovery
Spontaneous recovery the return of a previously extinguished conditioned response
Stimulus discrimination
Stimulus discrimination the process in which an organism only demonstrates the conditioned response to the conditioned stimulus and not to stimuli similar to it
Stimulus generalisation
Stimulus generalisation a process in which the learner demonstrates the conditioned response to stimuli that are similar to the conditioned stimulus
Conditioned emotional responses
Conditioned emotional responses an emotional response to a stimulus that doesn’t naturally produce that response, learned through the process of classical conditioning
Operant conditioning
Operant conditioning learning through the association of a behaviour and the consequence it receives
Antecedent
Antecedent a stimulus that causes a voluntary behaviour to occur
Behaviour
Behaviour a voluntary action in response to an antecedent
Consequence
Consequence an event following an action that makes it either more or less likely to occur again
Reinforcement
Reinforcement a type of consequence that makes the behaviour more likely to occur again
Positive reinforcement
Positive reinforcement when a stimulus is added in order to encourage a behaviour to occur again
Negative reinforcement
Negative reinforcement when a stimulus is removed in order to encourage a behaviour to occur again
Punishment
Punishment a type of consequence that makes the behaviour less likely to occur again
Positive punishment
Positive punishment when a stimulus is added in order to discourage a behaviour from occurring again
Response cost
Response cost (also known as negative punishment) when a stimulus is removed in order to discourage a behaviour occurring again
Extinction
Extinction when the conditioned behaviour no longer occurs in response to an antecedent, for an extended period of time
Spontaneous recovery
Spontaneous recovery when the behaviour occurs in response to the antecedent again, following a period of extinction
Stimulus discrimination
Stimulus discrimination when the behaviour occurs in response to a specific antecedent only
Stimulus generalisition
Stimulus generalisation when the behaviour occurs in response to a similar, but different, antecedent
