PSYC 450 EXAM 2 QUESTIONS WITH CORRECT
WELL DETAILED ANSWERS
Overt vs covert attention - ✔✔Overt Attention is attention with the direct use of a sense organ.
- It's turning your head or moving your eyes.
Covert Attention is attention without looking
- seeing something with your peripheral
Ponser's Pre-cueing Experiment - ✔✔An experiment that proved that attention can enhance the
processing of a stimulus.
- person had to stare at the center and respond to pointing arrows. when attention was to the right and
the arrow pointed to the right, they responded quicker.
Feature Integration Theory - ✔✔Broke down objects into features, then recombined them to create
perception of the object
Illusory Conjunction - ✔✔incorrect combination of features from different objects. (caused incorrect
answer)
divided attention tasks - ✔✔second-long pictures of shapes and black numbers. participants would have
to name the shapes they saw by the numbers
- evidence of feature integration theory
Balint's syndrome - ✔✔Inability to focus attention on individual objects
- parietal lobe damage
fixation - ✔✔when the eye pauses to look at something
saccades - ✔✔the movement of eye in between fixations
, Corollary Discharge Theory - ✔✔explains why we don't perceive the world as moving when we move our
eyes.
-corollary discharge signal (copy of motor signal of eyes moving that gets sent to the brain)
-image displacement signal (signal sent to brain when image on retina changes)
-Comparator (receiving area of brain. Helps decipher whether world is moving or eyes are moving based
on what signals it receives)
-- IDS alone: movement perceived
--CDS alone: no movement perceived
bottom up affects of attention - ✔✔involuntary
salience - ✔✔any physical characteristics of an object that makes it stand out
(red pepper in green bush)
- bottom-up
attentional capture - ✔✔involuntary shift in attention because of a highly salient stimulus (police lights
in mirror)
- bottom-up
top-down affects on attention - ✔✔is voluntary
-schemas
-task demands
conjunction search - ✔✔patient looks for an object based on a combination of features
feature search - ✔✔patient looks for an object based on which one stands out
