- 1What is learning?1. Change in behave via acquisition of a new response or supression of existing response
2. Its Relatively long lasting compared to other behaviours
3. Not all long-term changes in behaviour are due to learning e.g. maturation - 2Learning again?An enduring chang in the way an organism responds based on experiences
- 3Learning is the ability to:?What should be ignored and attended too
Recognise relationships between environmental events
Adapt to changes in environment
Necessary for surviival
Enduring - but can be changed with future learning
Key to association - 4Can Plants Learn?Yes seeds can learn and choose the best growth direction
Also note all organism have the capacity to learn - 5Non-Associative Learning FactsUse startle response (jump) and orienting response (turning and looking)
Learning from the result of the impact of ONE particular stimulus - 6Habituation FactsWe stop responding due to the decrease in stre of the elicited response that may occur with repeated responses
e.g. a fridge - 7HabituationResponses depletes with exposure
- 8Orientating responseThere from birth and we move towards the direction after we orient to it we get use to it and move away and we habituate
- 9Dielenbergs findings on HabituationRats over time hide less when they got use to the cats odour
- 10Sensory Adaptation difference with HabSensory is short lived
Hab isnt - 11What is Dishabituation?Is when habituation goes away due to the addition of a sensiting stimulus that reorients it . e.g u get use to a fridge noise then someone knocks on the door and u are like fuck this fridge
- 12Dishabituation factsIs the recovery to an already habituated stimulus
- 13Habituation leaton studyPresented once a day = produces long term
Presented every 3 seconds = deeper habituation but it doesnt last
Short Term presents spontaneous recovery - 14Sensitationincreases with exposure
Affects the CNS by decreasing the sensory threshold to significant external events
Its not stimulus specific - 15Davis Study60db tones rats undergo habituation
tones 80db undergo sensitation - 16Why the difference?Loud background - enhancing reactivity --) more greater startle reaction e.g. noisy restaurant eat more
Quiet background --) startle reaction is habituated e.g. quiet we don't eat - 17Sensitisation and Habituation occu occuring at the same time study?Simple stimulus --) progressive habit
Complex -- ) sensitsation --) habiutation
Indicatin they are dual processess depends on nature of stimulus - 18Habituation or sensitisation?Low intense - habit
High - sen
Inbetween starts with sensitiations then habituation
Evolution adaptive effects can often override intensity -- e.g. baby crying mother can't habituate to it - 19Sensitisation is said to be a proceess that opposes the effects of habituation all the time? True or falseFalse it happens often but not in all situations
- 20Intial increase in responsiveness to a stimulus is habituation? True or false?False its sensitisation
- 21Sensitisation may not only occur early but also when another unexpected stimulus from another modality appears? True or falseTrue
- 22Sensitisation factsArousal of CNS occurs in the state system - its stimulus general
- 23Habituation factsIs stimulus specific happens in the stimulus response system
- 24Groves and Thompsons findingHabituation is the decreased ability of the stimulus to elicit the response . The threshold is increased for irrelvant stimulus
- 25Reflexivve responses factsIncrease or decrease depends on environment
They are modifiable to avoid irrelevant stimulus and focus on important stuff
