L1: Classical Conditioning Flashcards
What is habituation in classical conditioning?
- when a novel stimulus initially produces a strong response from an organism,
- but this response lessens over time with repeated exposure to the stimulus
Why does habituation occur?
- because an organism tends to attend to novel stimuli as they may signal danger or reward (orienting reflex)
- but if stimulus turns out not to signal imminent danger/ reward, intensity of response declines as organism learns that the stimulus does not warrant its attention
What is sensitization in classical conditioning?
- involves an increase in the behavioral response to a stimulus
- occurs when an organism becomes more responsive to certain aspects of the environment, often in response to noxious/fearful stimuli
When does sensitization typically occur?
- when noxious or fearful stimuli are presented to an organism
provide an example of sensitization
- when individual feels “touchy” or hypersensitive after experiencing an unpleasant/fearful event
- in this case, the individual becomes more responsive to potential threats in their environment.
provide an example of sensitization
What are reflexes in the context of behaviour?
- unlearned/innate automatic responses to specific stimuli.
Define species-specific behaviours (instincts)
- Complex, unlearned behaviors genetically determined in certain animals
- exhibited under specific circumstances - not subject to significant modification through learning
Provide examples of species-specific behaviours (instincts).
- hibernation, nest building, mating behavior, and nut burying behaviours (squirrels)
What is imprinting, according to Konrad Lorenz?
- combination of learned & instinctive behaviour, involving the formation of attachment between an organism and an environmental object.
- occurs during a specific period of heightened sensitivity- known as the critical period.
Explain single-trial learning in the context of imprinting
- refers to the process where an animal learns to fixate its attention on the first object
- learning to follow the first object/stimulus encountered persistently
- example: young ducklings, which imprint on the first moving object they see after hatching, usually their mother/another moving stimulus
Define learning.
- relatively permanent behaviour change from experience, distinct from temporary factors. (fatigue, illness, maturation, intoxication)
- translation of learning to behaviour may not occur immediately
What is associative learning?
process of learning by associating stimuli or behaviors with specific outcomes.
What are the two types of associative learning ?
Classical conditioning and instrumental (operant) conditioning
What is instrumental conditioning?
Learning how to obtain desirable outcomes and avoid undesirable ones
What is classical conditioning?
- form of associative learning
- an organism learns to associate two different stimuli
- leading to a change in behaviour/response to one of the stimuli based on its association with the other
Give examples of classical conditioning in daily life.
Associating the perfume of a favorite teacher with favorable memories of school
OR
having difficult subjects in the morning leading to a mild dislike for mornings.
What experiment did Pavlov conduct to study classical conditioning?
- Pavlov conducted an experiment on dogs
- he fitted them with an oesophageal and gastric fistula.
- The dogs could be fed, but the food did not reach their stomachs.
- observed that stimulation of one part of the body (mouth) could cause a reflexive response in another (gastric fluids)
What did Pavlov notice during his experiment?
- noticed that mere sight of food could cause the release of gastric fluids in the dogs,
- which is known as a conditioned reflex.
- an example of classical conditioning
What is the process of “Acquisition” in classical conditioning?
- For the conditioned response (CR) to be produced, the conditioned stimulus (CS) and the unconditioned stimulus (US) must be paired a number of times.
- CS must be presented before the US
