The stroop effect
An incongruous stimuli dont match we experience a conflict between two levels
Who first observed the Stroop Effect and when?
John Ridley Stroop in 1935.
What happens during congruent stimuli?
Both levels of processing match (e.g., the word “orange” written in orange ink), so there is no conflict.
What happens during incongruent stimuli?
There is a conflict between two levels of processing:
Word-reading (orthographic)
Color-naming
Why are responses slower in the Stroop task?
Because we must inhibit automatic word-reading to correctly name the ink color — this causes interference.
What kind of interference does the Stroop Effect demonstrate?
Cognitive interference — when automatic processing (reading words) conflicts with controlled processing (naming colors).
Represtation
A symbol or thing which represents something else
Categories functions
Classification
Communicate
Conserve
Classification
Allows us to treat different things as the same
Communication
We communicate using words that refer to more abstract ideas/concepts
Conserve
Mental space
Why would categories be useful
Let’s you infer rather than direct observation
Superordinate levsl
A general category
— like furniture
Preffered level (basic level)
What is Mainly used naturally
Like chair
Subprdinate levrl
Specific category, like a brand
Analogous problems
problems that have a similar structure or relationship to another problem, even if the content is different
Controlled processing system
Concious explicit
Effortful, requires motivation
Slower
Often more accurate
Automatic processing system
Often unconscious, implicit
Requires little effort
Faster
Can be error prone
Heuristic
Process of inference by intelligebt guess work, relying on general knowledge gained bu experience
Availability
We tend to make estimates/judgements based on what comes yo mind easily
The availability heuristic
We tend to make inferencez and estimates based on what comes to mind easy
The representativenezz heuristic
People think something is more likely if it reflects their beliefs about a situation
Dual processing
Controlled processing system
Automatic processing system
Framing effevr
a cognitive bias where people’s decisions are influenced by how information is presented, rather than its conten
