Learning and Memory Flashcards
What is learning?
The prices of quiring new and relatively permanent information or behaviours
What are the three types of learning?
Nonassociative; associative; and observational
What is nonassociative learning?
A change in response to a stimulus due to repeated exposure to that stimulus
What is a stimulus?
Any event or situation that evokes a response
What are the two types of non-associative learning?
Habituation and sensitisation
What is habituation?
A process in which the magnitude of response to a specific stimulus decreases with repeated exposure to the stimulus
What for key properties characterise habituation?
1) frequency of stimulus presentation
2) strength of stimulus
3) dishabituation
4) habituation of dishabituation
What properties of habituation define the magnitude of response?
Frequency and strength
What is dishabituation?
Following habituation, a single presentation of a different stimulus restores the response to the original stimulus
What is habituation of dishabituation?
The more the response to return the response of the original stimulus, the less effect the new stimulus presents
What is sensory adaptation?
A physiological phenomenon that occurs when an animal can no longer detect a repeated stimulus
What is fatigue?
It reveals a progressive decrease in response due to incapacitated muscles
What is sensitisation?
The process in which the magnitude of response to a stimulus increases with repeated exposure to that stimulus
What is the dual process theory of habituation and sensitisation?
It states that both neural processes occur at the same time and the resulting behavioural responses is a net effect of the two processes
What system does habituation stimulate? When is this system activated?
S-R system; is stimulated every time a stimulus elicits a response
What system does sensitisation stimulate? When is this system activated?
State system; only activated with particularly arousing events
What is associative learning?
Learn that one event occurs with another
What are the two types of associative learning?
Classical conditioning and operant conditioning
What is conditioning?
The process in which a particular behaviour becomes dependent upon the presence of a stimulus
What is a stimulus?
Any event or situation that evokes a response
What are three types of stimuli?
Neutral, conditioned, and unconditioned
What is a neutral stimulus?
A stimulus then usually produces no specific response other than focusing attention
What is an unconditioned stimulus?
A stimulus that naturally and automatically triggers a response
What is a conditioned stimulus?
A stimulus that was previously neutral, but after becoming associated with the unconditioned stimulus it eventually elicits a conditioned response
What is an unconditioned response?
A response that is unlearned and occurs naturally with presentation of an unconditioned stimulus
What is a conditioned response?
A learned response to previously neutral but now conditioned stimulus
When does classical conditioning occur?
Occurs when a condition stimulus is paired with an unconditioned stimuli us, causing an association to form between the two
Who started classical conditioning?
Ivan Pavlov
What is acquisition?
The initial learning of the stimulus response relationship
In what order are the condition stimulus and the unconditioned stimulus presented in forward conditioning?
The condition stimulus precedes the presentation of the unconditioned stimulus
In what order are the condition stimulus and the unconditioned stimuli us presented in simultaneous conditioning?
The condition stimulus and the unconditioned stimulus are presented and terminated simultaneously
What is another name for higher-order conditioning?
Second order conditioning
What is higher-order conditioning?
And existing condition stimulus is paired with the neutral stimulus creating a second and often weaker condition stimulus
When are the unconditioned stimulus and conditioned stimulus presented in backward conditioning?
The unconditioned stimulus is presented before the condition stimulus
What happens in trace conditioning?
The condition stimulus is presented and then the unconditioned stimulus is presented; there is no overlap
What happens in delay conditioning?
The conditioned stimulus is presented before the unconditioned stimulus and continues throughout the presentation of the unconditioned stimulus
What are the two types of forward conditioning?
Trace conditioning and delay conditioning
What is extinction in relation to classical conditioning?
The diminishing of a conditioned response due to repeated exposure of the conditioned stimulus in the absence of the unconditioned stimulus
What is spontaneous recovery?
The reappearance of a weekend conditioned response after a rest period
When the stimulus generalisation occur?
It occurs when a conditioned response to a specific stimulus transfer to the other stimuli to the conditioned stimulus
What is stimulus discrimination in classical conditioning?
The learned ability to distinguish between a condition stimulus and other stimuli that have not been associated with an unconditioned stimulus
What is operant conditioning?
Learning that occurs by associating in action with the consequence
What is another term for operant conditioning?
Instrumental conditioning
What are two names for behaviour that is a result of operant conditioning?
Instrumental behaviour or goal directed behaviour
What does the Law of Effect contend?
Favourable consequences strengthen behaviour and unfavourable consequences weaken behaviour
What is the procedure by which operant conditioning behaviour is learned?
Shaping
What does shaping look like in operant conditioning?
Reinforcement of successive approximations toward a desired response
What is instinctive behaviour in operant conditioning?
Species specific unlearned behaviour that is often a response to particular environmental stimuli
What is extinction within operant conditioning?
The reduction of an instrumental behaviour when it is no longer reinforced
In operant conditioning what does a discriminative stimulus project?
The presence of reinforcement
In operant conditioning what does a extinction stimulus project?
The absence of reinforcement
What is acquisition in classical conditioning?
The period of time where the condition stimulus comes to elicit the conditioned response
What is extinction in classical conditioning?
Diminishing of a conditioned response through repeated exposure of the conditioned stimulus in the absence of the unconditioned stimulus
What is spontaneous recovery in classical conditioning?
Reappearance of a weekend conditioned response after a rest period
What is generalisation in classical conditioning?
The tendency to respond to other stimuli similar to the conditioned stimulus
What is discrimination in classical conditioning?
The learned ability to distinguish between a condition stimulus and other stimuli that have not been associated with an unconditioned stimulus
What is acquisition in operant conditioning?
The period in time where behaviour becomes associated with a consequence
What is extinction in operant conditioning?
Reduction of an instrumental behaviour when it is no longer reinforced
What is spontaneous recovery in operant conditioning?
Reappearance of a goal directed behaviour after a rest period
What is generalisation in operant conditioning?
The tendency to respond to stimuli similar to the reward paired stimuli
What is discrimination in operant conditioning?
The learned ability to distinguish between responses that are reinforced and responses that are not reinforced
What is reinforcement?
Any event that strengthens or increases the behaviour it follows
What are the four types of reinforcement?
Positive, negative, primary, and conditional
What is positive reinforcement?
Reinforcement strengthens a response by presenting a pleasurable event or outcome after the response
What is negative reinforcement?
Reinforcement strengthens our response by removing or reducing an unfavourable event or outcome
How does negative reinforcement differ from punishment?
Negative reinforcement increases a response by ending an aversive event
What is primary reinforcement?
It strengthens our response by presenting in unlearned reinforcing stimulus of innate biological values (food)
What is conditioned reinforcement? What is another term for this?
Secondary reinforcement; it strengthens our response by presenting a learned stimulus that game is reinforcing power to repairing with the primary reinforcer (grades and money)
What are two types of behaviours that describe negative reinforcement?
Escape and avoidance
What is escape in negative reinforcement?
Behavioural response that terminates and unpleasant stimulus that is already present
What is avoidance in negative reinforcement?
Behaviour that prevents an unpleasant stimulus
In operant conditioning what is a reinforcement schedule?
A pattern of the timing and reliability of the presentation
What are the two types of reinforcement schedules?
Continuous and partial (intermittent)
When is the response reinforced with continuous reinforcement?
A response is reinforced every time it occurs
When is the response reinforced with partial reinforcement?
A response is only sometimes reinforced
What are the four schedules of partial reinforcement
Fixed ratio, variable ratio, fixed interval, and variable interval
What are fixed ratio schedules?
A set number of responses is required for a reward
Where are variable ratio schedules?
A random number of responses required to earn a reward
What is a fixed interval schedule?
A set amount of time required before a response is rewarded
What is a variable interval schedule?
A very able or random amount of time is required before a response is rewarded
In operant conditioning what is punishment?
Any event that weekends or decreases the behaviour it follows
What are the two types of punishments?
Positive and negative punishments
What is positive punishment?
Weakens a response after presenting an aversive stimulus after the response
What is negative punishment?
It weakens a response by removing a desirable stimulus following the response
What is expectancy in classical conditioning?
A belief that something will happen
What is a surprise in classical conditioning?
A discrepancy between what you expect and what you get
What is the incentive in operant conditioning?
The value of award, or the expectation in anticipation of its pleasure
What do operant conditionists use to control the environment?
Produce deliver actions
What do you behaviourists attribute changes in instrumental behaviour to?
Various consequences
What do cognitive theorists attribute learning to?
The incentive of a reward rather than the reward itself
How do behaviourists and cognitive theorists argue that learning relates to a reward?
Behaviourists argue that the presence of a reward was sufficient for learning
Cognitive theorists believe that a mental representation of the reward might also play a role
What is latent learning?
Learning that is not shown in performance until rewards are given for performance
What is a cognitive map?
A mental representation of an animals environment environment
What is biological predisposition?
The increased chance of developing a pattern of behaviour based on a genetic make up
What is instinctive drift?
The tendency of an animal to revert to instinctive, species typical behaviours that interfere with the conditioned response
What is another name for autoshaping? What does this term mean?
Sign tracking; and instinctive response to certain stimuli that has not been reinforced by reward or punishment
What is observational learning?
Type of learning by watching and imitating others
What is modelling?
The process of observing and learning specific behaviour
Observational learning is a form of what type of learning?
Social learning
What is social learning?
Learning that introduces the influential effects of a model
What is the model in social learning?
Someone of authority whose own behaviour changes the behaviour of another
Who performed the bobo doll experiment? What did this experiment demonstrate?
Albert Bandura; demonstrated that violence and aggressive actions by adults are learned and later performed by children
Who is the father of operant conditioning
B. F. Skinner
What was the BF Skinner’s main experiment?
Skinner Box; A box that contained a lever, speaker, light, a food dispenser, and advice that recorded responses. This design allowed Skinner to observe and animals control over its responses based upon their associated consequences
