- 1Behaviours selected for via evolution are either:Reflexive (i.e. sucking, blinking)
Instinctual (i.e. imprinting) - 2Behaviours selected for via experience:Learning: a reasonably permanent change in behaviour or knowledge
- 34 types of Learning:Habituation
Classical Conditioning
Instrumental Conditioning
Observational Learning - 4HabituationGetting used to something over time
e.g. becoming desensitised to violence - 5Classical ConditioningWhen two stimuli are repeatedly paired: a response which is at first elicited by the second stimulus is eventually elicited by the first stimulus alone.
- 6Evidence of Classical ConditioningPavlovs Dog Experiment
- 7Exam example for Classical Conditioning1. US -> UR
NS -> No Response
2. NS+US -> UR
3. CS -> CR - 8Who was little Albert?Demonstrated fear conditioning
Became frightened of anything that resembled a white rat (stimulus generalisation) - 9Compensatory Reaction HypothesisBody preparing for whats coming by doing opposite
The conditioned stimulus begins to elicit a compensatory after effect
E.g. Insulin Injections
Drug Tolerance
Drug Overdose (Siegal, 1989) - 10Important Factors when aiming (NS becoming CS)Number of times the NS and US have been paired
Timing (forward conditioning is better than backward conditioning)
The CS must PREDICT the US. The CS should be both contingent and contiguous with US - 11ExtinctionThe CR will slowly decrease if the CS is presented without the US repeatedly
- 12Spontaneous RecoveryWhen the CS elicits the CR again after a period of extinction
- 13Stimulus GeneralisationWhen a CR occurs in response to stimulus similar to the CS (e.g. Little Albert)
- 14Stimulus DiscriminationWhen a stimulation similar to the CS do not elicit the CR
- 15Generalisation GradientsAs stimuli gets closer to resembling the CS they produce more CR
- 16Discrimination Training:When the CR only occurs in response to the CS
- 17FloodingTreatment for phobias - patient is placed straight into a highly feared situation
- 18Systematic DesensitisationTreatment of phobias and anxiety - patient is gradually introduced to stimuli that are more and more fear inducing
- 19BlockingWhen a good predictor of the US already exists so conditioning does not occur
- 20Higher Order conditioningWhen a once neutral stimulus has been so well conditioned, it starts to act as the US to condition another neutral stimulus
- 21Sensory PreconditioningWhen an association already exists between two stimuli and one of those stimuli is conditioned in the absence of the other stimuli, but the other stimuli elicits the same CR even though it was never explicitly paired with the US
- 22Biological Constraints to ConditioningIt is easier to condition the US and CS if they appear to belong with each other
External pain; external cause
Internal pain; internal cause - 23Taste Aversion StudiesThe Hungry Coyotes
Chemotherapy - 24Instrumental ConditioningBehaviour is modified by the reinforcing or inhibiting effect of its consequence.
- 25Thorndike's Law of EffectPositive consequences will increase the likelihood of a response, while negative consequences will decrease the likelihood
- 26Skinner's Law of EffectPositive = adding something
Negative = taking something away - 27ReinforcementIncreases the likelihood of the behaviour
Negative - removing a stimulus to increase the behaviour
Positive - adding a stimulus to increase the behaviour - 28PunishmentDecreases the likelihood of the behaviour
Negative - removing a stimulus to decrease the behaviour
Positive - adding a stimulus to decrease the behaviour - 29Primary Reinforcers/Punishers are...Inherent/Obvious
- 30Conditioned Reinforcers/Punishers are...After becoming associated with primary reinforcers/punishers
- 31Token ReinforcersCan be exchanged for a primary reinforcer (e.g. money)
- 32Succesive ApproximationWhen shaping behaviour, you start rewarding a broad range of close responses, then progressively narrow the range of rewarded responses
- 33Schedules of ReinforcementPresenting reinforces in a particular pattern over time
- 34Continuous ReinforcementGood for learning new behaviour or changing behaviour quickly
- 35Partial/Intermittent ReinforcementGood for maintaining behaviours
- 364 Schedules of Partial ReinforcementVariable Interval Schedule (VI)
Variable Ratio Schedule (VR)
Fixed Interval Schedule (FI)
Fixed Ratio Schedule (FR) - 37IntervalPassage of time
- 38RatioNumber of responses
- 39VariableVaries around an average
- 40FixedReinforcement is given after fix period of time/number
- 41Partial Reinforcement Extinction EffectIt is harder to extinguish behaviour that has been rewarded on a partial reinforcement schedule - resistant to extinction (e.g. gambling)
- 42Premack's PrincipleHigh probability behaviours can be used to reinforce and increase the likelihood of low probability behaviours i.e. you can watch an episode after you watch a lecture
- 43Biological Constraints of Instrumental ConditioningTrained animals via instrumental conditioning for advertising
Behaviours eventually drifted towards more instinctive behaviours
i.e. raccoons rub coins together because that resembles their food gathering behaviour - 44Latent LearningLearning that happens when there appears to be no reinforcements or punishment. Often unapparent until reward or punishment is offered
- 45Tolman & HoznikLatent Learning: showed rats a maze without food incentive. Once food was introduced they learnt the maze much quicker than control rats who hadn't seen the maze before
- 46Observational LearningLearning by observation
- 47Evolutionary RationaleGood way to learn adaptive behaviours compared to other learning styles
- 48Cook and Mineka (1967)Taught monkeys to fear snakes by showing them a video of a monkey reacting with fear to a toy snake
- 49Bandura et al (Two experiments)Kids who watched an adult beat up a bobo doll also bet up the doll
Kids who were scared of dogs were less scared after watching a video of a child playing fearlessly with dogs - 504 Key Processes of Observational LearningAttention
Retention
Production
Motivation - 51Is the model similar or different to the desired behaviour?Similar
- 52The model is competent. True or false?True
(Good Past Experiences with Observer) - 53Does the model have higher or lower prestige?Higher
- 54Can you involve multiple models?Multiple is better
- 55Poche et al Stranger Danger Education studyKids learnt to verbally say no and physically run away
- 56The KelloggsGua the chimp learned to understand some instruction, never made any English words
- 57The HayesVicki was able to say "papa, mama, and cup" Only after extensive training
- 58Why was it so hard for chimpanzees to speak?Not anatomically suited for human speech
- 59Sign Language EvidenceThe Gardners: Washoe, knew 160 signs but could understand many more
Terrace: Nim Chimpsky, pointed out lots of deficits in chimp language - 60Symbol Based LanguageKanzi - eventually could produce 200 lexigram symbols and understand approx 500 spoken words
= 2/2.5 year old human
