dual process theory 1
System 1: Intuitive (Heuristic mental shortcut)
* Fast & Intuitive
* Unconscious, generates impressions, intuitions, and feelings
* First resort of cognitive processing
* Effortless
* Automatic
* Prone to error
dual process 2
analytical
* Slow & Rational
* Deliberate, conscious, effortful, and logical, and calculated
* Can override System 1 when needed.
* Cognitive load
Anchoring Bias
rely heavily on the first piece of information (anchor) presented –> individual’s decisions and judgments.
process
study name
Tversky and Kahneman Study
aim
investigate how people make decisions and judgments in uncertain situations
Procedure
High school students of 16-18 years were randomly assigned a group. Each group was shown an arithmetic multiplication problem and instructed to estimate the answer in 5 seconds. The groups were each given one condition, in ascending order (1x2x3x4x5x6x7x8) or descending (8x7x6x5x4x3x2x1).
Findings
The median answer for ascending groups was 512, and the median for descending groups was 2250. The actual answer is 40320.
confirmation bias
process information in ways that support existing beliefs, while ignoring information that contradicts.
3 reasons why we use anchor bias
Why we use confirmation bias
schema theory assimilation
taking new info + fitting it into existing schema
accomodation
modifying existing/creating new schemas
schema
mental structure reprenting what something is
schema theory
people constantly adjust/maintain schemas while interacting with the environment –> learning & cognitive development
schema study
zachary hendricks (2021)
IV: story, time (familiarity)
DV: memory
cognitive load theory
extraneous: extraneous factors to task –> difficulty to process info
germane: effort needed to process info
intrinsic: complexity of content
chunking
chunking study
Miller
* IV: no. chunks
* DV: recall
Cognitive approach
Schema theory & cognitive load theory: processing info through schemas, limited by working‑memory capacity
social strength
schema theory, hendricks: familiarity with culture (emic) –> accurate/better memory
Cognitive/reductionist limits
biological/reductionist limits
social/rdeuctionist limits
