Cognitive Neuroscience (2) Flashcards
________ ________ - Brief period in psych where we shifted to studying the mind as a computer
Cognitive revolution
studying the mind as a computer gave rise to _________ ___________ approach
Information Processing approach
what is the information processing approach
analyses cognition as a set of steps for processing information
Information Processing approach doesnt study what happens in the brain, rather ….????
Information comes in as _____, information is _______
Information Processing approach doesnt study what happens in the brain, rather abstractly how the mind processes things
Information comes in as bits, information is abstract
Experiment: Sternberg test
Sternberg used ______ ______ to measure _____ _______
reaction time to measure memory retrieval
Experiment: Sternberg test
What makes this abstract?
All we do here is measure reaction time, making it abstract
Experiment: Sternberg test
explain how task/experimetn works
Experiment: Sternberg test
P’s given list of random set of letters to remember, once removed, single letter pops up - task is to indicate whether the single letter was in the set as quickly as possible
Experiment: Sternberg test
results?
Found a linear relationship, more digits shown, the longer it takes you
Experiment: Sternberg test
_______ ______ - Participant sees all the letters at once
________ ______ ________ - Participant sees one letter at a time
Parallel search - Participant sees all the letters at once
Serial Exhaustive Search - Participant sees one letter at a time
Experiment: Sternberg test
Indep and dep variables?
IndVar = Number of items in the memory set
DepVar = Reaction time
Informations processing is abstract:
By measuring reaction time we can infer _______ ________ we cannot _______ them
By measuring reaction time we can infer mental process we cannot observe
what is a more accurate way to explain the fallacy that we use 10% of our brain
More accurate that we are only conscious of a small proportion of the overall activity in the brain
Why do psych myths, such as the multiple intelligences thery, persist
Difficult to text/falsify
there do exist differences in intelligence, but its hard to test them
give of examples of psych terms we use differently on the day to day
“dopamine hit” as a metaphor on conceptual framework rather than facts
“Paying attention” used differently than how a neuroscientists may use the term attention
define reverse inference error
inferring involvement of a specific cognitive process from observed brain activation during a task
