Lecture 1 Flashcards
What is cognitive psych?
Doing a series of things at the same time e.g. Understanding (language skills), learning (memory encoding)…
What does congesco mean?
I know
At what time did they show an interest in mind/language?
1950-1980
When did cognitive psychology become a dominant approach?
1970
What is the mind-computer metaphor?
Looking at the way humans process information. Looks at internal processes like perception, attention, language, thinking…
Input in environment- mediational process- output behavior
What is mediational behavior?
It occurs between stimulus and response: a mental event
What are the styles in information processing approach?
Serial: only one process at a time, next one starts after that one finishes
Bottom up: processing is determined by environmental stimuli rather than prior knowledge/expectations
What is the order off events processing from perception?
Stimulus, attention, perception, thought processes, decision, response/action
Settings for research
Experimental/physical science(cognitive psychology): established cause and effect by testing predictions. Firm grounds for falsification, low ecological validity
Naturalistic: (anthropology) no strong basis for hypothesis needed, string ecological validity, systematic bias? No causation
Quasi-experimental: (forensic) can establish causation via statistical analysis or correlation. Can be applied to the real world, useful to help create hypothesizes, nusiance variables
What is experimental cognitive psych?
Experiments in healthy individuals, sheds light on our cognitive processes
What is cognitive neuroscience?
Evidence from the brain to understand cognition
What is cognitive neuropsychology?
Experiments on brain damaged patients
What is computational cognitive science?
Developing computational models (experimental findings to explain cognition)
What are the two forms of behavior measured?
Reaction. Time between onset of stimulus and motor response
Accchracy (clues about content/capacity)
What is donders subtraction method?
Contains 3 tasks:
1) Stimulus discrimination: GO/NGO and look at reaction times. Press orange if stimulus presented, pink if nothing-accuracy
2) response selection
3) response execution
Choice rt takes 800ms, GO/NGO TAKES 500ms and simple rt takes 200ms
