Basic concepts Flashcards
3 Issues with introspection
- Some mental processes being unconscious
- Scientific data needs to be reliable and objective
- Cant describe the pictures in our minds all the time
Introspection
a psychological process that involves looking inward to examine one’s own thoughts, emotions, judgments, and perceptions.
Pavlov’s work
Classical conditioning, salivation of dogs, some dogs would salivate at the sight of the experimenter. CR decreased after 20 trials (extinction) he presented the stimulus after extinction and found spontaneous recovery of the CR.
Behaviourism
Observable facts, much more scientific than introspection, stimuli and response are measurable effects, e.g., ‘little albert study
Thorndike study (1898)
Studied operant conditioning see how cats would escape from the box, they learned gradually, from this he proposed the law of effect
Thorndike law of effect 1911
The development of a relationship between a stimulus and a response. link between lever and being trapped so will push lever every time trapped in the box.
B.F. Skinner
More radical behaviourism rejected unobserved variables as ‘explanatory fictions’ (not based on scientific knowledge or directly observable events
Problems with behaviourism
One experiment showed rats swimming to food in a flooded maze when it was drained went straight to the food. In another experiment they had 10 days to explore goal box baited on the 11th day and the 12th day ran straight to the goal. Tolman argued the rats behaved as if they had a purpose, they seemed to expect food responding to cognitions not responses
The transcendental method to studying cognition
effects may have causes, we can infer unobservable causes from observable evidence
Cognitive revolution of 1960s
Measurements of more observable things: accuracy, speed and eye movement
Models of cognition
we build models of our mental processes to help is made predictions that can be tested which helps us understand how we think
Reinforcement
Positive: food presented upon pressing the lever
Negative: a lour noise that is terminated by pressing the lever
Punishment: a shock associated with a certain area
