Psych 375 Cognition Midterm Exam
Questions With Correct Answers
Sternberg Memory Search - CORRECT ANSWER✔✔-The time needed to
| | | | | | | | |
recognize a digit increases with the
| | | | |
number of items in the memory set.
| | | | | |
The straight line is the linear function that fits the data best
| | | | | | | | | | |
TMS: Transcranial Magnetic Stimulation - CORRECT ANSWER✔✔-Virtual
| | | | | | |
lesions
Magnetic pulse induces electric field in cortex
| | | | | |
fMRI: Functional Magnetic Resonance Imaging - CORRECT ANSWER✔✔-
| | | | | | |
Blood Oxygenation Level Dependent (BOLD)
| | | |
signal
- Ratio of oxygenated to deoxygenated hemoglobin
| | | | | |
- Indirect measure neural activity
| | | |
EEG: Electroencephalogram, ERP - CORRECT ANSWER✔✔-Localization
| | | | | |
poor, but possible
| |
With enough trials can see precise timing
| | | | | |
,Advantage: temporal precision | |
Single Cell Recording - CORRECT ANSWER✔✔-Measuring response of
| | | | | | | |
single neurons to visual stimulus
| | | |
COGNITIVE PSYCHOLOGY - CORRECT ANSWER✔✔-The science of how
| | | | | | | |
the mind is organized to
| | | |
produce intelligent thought and how it is
| | | | | |
realized in the brain. | | |
The study of mental processes including
| | | | |
how people think, perceive, remember,
| | | |
and learn.|
Scientific method - CORRECT ANSWER✔✔-Systematic steps applied to
| | | | | | | |
scientific problem |
Often a single experiment cannot answer our question
| | | | | | |
definitively, so we rely on the convergence of evidence
| | | | | | | |
Experimental research terminology - CORRECT ANSWER✔✔-1. Pick (at
| | | | | | | |
least) two variables: one to manipulate
| | | | |
and the other to observe (measure)
| | | | |
A. Manipulated variable = Independent variable (IV) or
| | | | | | |
,"cause"; must have at least 2 levels/ groups
| | | | | | |
B. Measured variable = Dependent variable (DV)
| | | | | |
2. Use large enough sample size (ideally,
| | | | | |
randomly selected) & random group assignment
| | | | |
(IV); measure outcome (DV)
| | |
3. Unlike correlation, true experiments provide
| | | | |
evidence for causality | |
Common behavioral methods - CORRECT ANSWER✔✔-Response time:
| | | | | | |
How quickly respond to stimulus
| | | |
or complete task (aka speed)
| | | |
Accuracy
- Ex. Percentage correct on memory test
| | | | | |
Face Identification (Example of a Behavioral Method) - CORRECT
| | | | | | | | |
ANSWER✔✔-Combinations of same/different upside down/rightside | | | |
up faces|
Average reaction time for each type of face
| | | | | | |
Compare (statistics) -difference in response time
| | | | |
for correct match when 2nd is right-side up vs.
| | | | | | | |
upside down? Yes. People slower to decide if faces are same when face
| | | | | | | | | | | | |
inverted vs. upright | |
, Accuracy vs. Response Time | | |
| Measure accuracy of responses rather than (or in
| | | | | | |
addition to) response speed
| | |
|People more accurate in deciding faces are same when faces upright
| | | | | | | | | | |
compared to inverted | |
Cognitive Subtraction Method - CORRECT ANSWER✔✔-Stimulus->Mind-
| | | | |
>Response
Neuropsychology - CORRECT ANSWER✔✔-Neuropsychology studies the | | | | | |
structure and function of the brain as they relate to specific
| | | | | | | | | | |
psychological processes and behaviors. It's an experimental field of
| | | | | | | | |
psychology that aims to understand how behavior and cognition are
| | | | | | | | | |
influenced by brain functioning and is concerned with the diagnosis and
| | | | | | | | | | |
treatment of behavioral and cognitive effects of neurological disorders.
| | | | | | | | |
Neuropsychology seeks to discover how the brain correlates with the | | | | | | | | | |
mind.
Lesion Study|
Phineas Gage |
Phineas Gage - CORRECT ANSWER✔✔-A large iron rod was driven
| | | | | | | | | |
completely through his head, destroying much of his brain's left frontal
| | | | | | | | | | |
lobe, and for that injury's reported effects on his personality and
| | | | | | | | | | |
behavior over the remaining twelve years of his life—effects sufficiently
| | | | | | | | | |
profound (for a time at least) that friends saw him as "no longer Gage".
