Final Flashcards
(30 cards)
Information theory
The information provided by a particular event is inversely related to the probability of its occurrence
Hick- Hyman law
Increasing the # of choices a person has will increase the decision time logarithmically
Broadbent filter modelling
Filters
Semantic richness
The amount of meaning associated with a concept
Interactionism
- mind & brain are desperate entities that interact and influence each other
Epiphenomanelism
Mind by- product of brian processes, uniderictional- the only way to study the mind is to study the brain
Isomorphism
Mental events share same structure as neural events (not 1-1)
Parallelism
- mind &a brain are two aspects of same reality
1-1 correspondence
Feature detection
- recognize pattern on basis of feature or property
Hen rule
Wire together fire together
3 basic elements of connection isn’t models:
1) info can be broken down into elementary units
2) there are connections between these units
3) connections can operate in parallel
Word superiority effect
- easier to identify letters that were briefly presented in words )compared to letters presented alone)
The grand illusion
The illusion that what we see in our visual field is a clear and detailed picture of the world
Change blindness
Inability to detect changes in an object or scene
Amount of information
Stimuli that occur less frequently carry more information which leads to slower processing
Richness of information
- information with more associated features will have richer representations
- richer representations will be processed more quickly
Visual “pop out” effect
Targets perceived almost instantaneously, even when there are many fist actors
Feature search
When the target differed from distractions along 1 feature dimension (speed does not vary with set size)
Conjunction search
The target & distractors differ on a conjunction of features
- slower than feature search
- slower with larger set size
Prosopagnosia
Patients lose ability to recognize faces
Selective attention
- when exposed to two events simultaneously, but only attend to one of them
- consistent with early selection theory of attention
Stroop interference effect
- in a task in which a person is instructed to respond to one aspect of a stimulus while ignoring another aspect responding is difficult if the two aspects are inconsistent (or colour list)
- more consistent with late selection models (both relevants and irrelevant stimuli are initially perceived but irrelevant stimuli is later ignored)
2 fundamental elements of a stroop task:
- Conflicting responses
2. Competing response is prepotent or automatic
Strip effect brain mechanisms:
Prefrontal cortex & anterior cingulate
