(2) Cognitive Psychology Flashcards
What is modern cognitive psychology?
Science of the mind, attention/perception/memory/ decision making
Opt-in vs Opt-out systems (results)
Opt-in countries have low rates, opt-out countries have high participation rates
Object memory - rate these categories from easiest to hardest to remember
Novel, exemplar, state
What is easier to remember, images or words (and why)
images, less brain power, recognition > recall
What is easier to recognize, novel or familiar items?
Familiar
Novel detection
Recognizing that the image/stimulus is unfamiliar
Bartlett: War of Ghosts findings
Accurate recalls rare, participants “create own story” unconsciously
Thinking and Memory are
- Product of experience
- Dynamic neural activation
- Not always perfect
- Context matters
3 Factors impacting decision making
Extent to which individual is
- Informed
- Sensitive
- Rational
Psychological perspective on decision-making
Typically choices are not independent
Computer analogy
Information input -> central processing -> behavioural output
(repeat until optimal output achieved)
Quality of input =
Quality of output
Use it or lose it phenomenon
- Consistent use -> improvement/ expertise
- Reinforces neural networks
Bayes Theorum
probability of event occurring depends on prior knowledge of conditions related to the event
Bayesian inference formula
Belief = (likelihood x prior knowledge)/evidence)
