Module 3 - Learning Flashcards
reflexive behaviour
a response to stimuli that are involuntary and free from conscious control
e.g. eye blinking, sucking and grasping (babies reflexive behaviour)
Homing
an ability of an organism to find it’s way back home
Imprinting
an instinctual behaviour where an offspring when they are born will imprint on the first moving objects that they see and they will then follow that object
Learning
a relatively permanent change in behaviour or knowledge as a result of experience
Habituation
is the decline in the tendency to respond to stimuli that have become familiar due to repeated exposure
Classical conditioning
a neutral stimulus is repeatedly paired with a stimulus that automatically elicits a particular response
the previously neutral stimulus becomes a conditioned stimulus that also elicits a similar response
Ivan Pavlovs
developed the theory about classical conditioning
What are the two types of behavior selected evolution?
Reflexive and instinctual
Instinctual Behaviour
an adaptive response to a stimulus in one’s environment
e.g. homing, imprinting and migratory behaviours
4 behaviours that are selected by experience
1) Habituation
2) classical conditioning
3) instrumental conditioning
4) observational learning
What happens during Habituation if stimulus presented is harmless?
Habituation is a behavior where it causes a first response to the stimulus introduced, but our system will learn to ignore it of proven that it is benign
meaning that if the same behavior is explicit and is proven to be benign, we will no longer react to the stimulus presented
-this occurs because repetition of response to the stimulus is very expensive and disruptive in terms of energy
- not time efficient for distraction of current task being performed
Unconditioned response
this is an animals natural response to stimulus (food) presented (salivation)
Conditioned response
this occurs when the addition of a neutral stimulus and unconditioned stimulus results in a conditioned stimulus which produces a conditioned response
Why do we still get an unconditioned response when NS + US occurs?
this is due to the presence of the unconditioned stimulus
Conditioned Emotional responses
Neutral stimulus associated with emotional events can elicit emotional responses
Stimulus substitution
this is the conditioned stimulus came to elicit a conditioned response via process whereby the conditioned stimulus comes equivalent to the unconditioned stimulus
- CS = US
Classical conditioning
this is a preparatory response
- conditioned stimulus act as a predictive stimulus
Compensatory-Reaction Hypothesis
this is when the unconditioned response and the conditioned response are opposite to each other
Acquisition
the process by which the conditioned stimulus comes to a conditioned response
i.e. process of how the neutral stimulus becomes a conditioned stimulus
Relationship between the number of NS and US pairings & US intensity
The more intense the US, the stronger the CR, and the quicker the rate of conditioning
Forward conditioning
where the conditioned stimulus occurs before the unconditioned stimulus
CS - US
Backward conditioning
where the conditioned stimulus occurs after the unconditioned stimulus
US - CS
Simultaneous conditioning
occurs when the conditioned stimulus and unconditioned stimulus are occurring at the same time
What is the best condition to produce a classical conditioned response?
the simultaneous conditioning because it does not give organisms time to prepare for the upcoming stimulus
Contingency
the assumption that classical conditioning depends on a contingent relation between the conditioned stimulus and the unconditioned stimulus
- the strength of conditioned response depends on how often the conditioned stimulus accompanies the unconditioned stimulus, and how often the conditioned stimulus accompanies no unconditioned stimulus
Extinction
If the conditioned stimulus presented without the unconditioned stimulus, then the conditioned response will gradually decrease
- the rate of decrease depends on factors such as initial response strength
Stimulus generalisation
a condition response formed from a conditioned stimulus will also give the same response to other stimuli which are similarly associated with feature of the conditioned stimulus
e.g. little albert was conditioned to have a fear response to a white rabbit, his fear response to other objects which had associated similar feature, in general from a rabbit was the same
stimulus discrimination
occurs when an organism learns to differentiate between the conditioned stimulus and other similar stimuli
e.g. Pavlov’s dogs discriminated between the basic tone sounded before they were fed and other tones (e.g. doorbell, because the other sound did not predict the arrival of the food
Generalisation Gradient
the more similar the stimulus to the training stimulus, the bigger the effect
Systematic Desensitization
combines ideas from extinction, stimulus generalisation and counter conditioning
- treatment for phobias and anxiety problems
Blocking
Classical conditioning does not occur if a good predictor of the unconditioned stimulus already exist
- classical conditioning is restricted
High-order conditioning
once a stimulus has become an effective conditioned stimulus for a certain conditioned response, then that stimulus can be used to conditioned other stimuli
