Visuospatial Memory Flashcards
Shepard picture experiment
subjects were shown 612 images, for 6 sec each - 100 sampled in a recognition test
results of Shepard picture experiment
subjects had 100% accuracy immediately and 2 hrs after the test, ~90% accuracy after 3 days, 87.5% after 1 week, and ~55% after 4 months
what is visual memory poor for?
unimportant/unattended details
stimuli that lack meaning
items that have similar foils
what is involved in good visual recognition?
attention to details
meaning/relevance of details
distinctive alternatives
Richer code hypothesis
memory is better for visual codes since they contain more information
proven to be incorrect
dual code hypothesis
visual materials produce a dual code, verbal and nonverbal
the dual code is why visual information is remembered better than other types of information
support for dual code hypothesis
concrete words (like apple) are remembered better than more abstract words (like peace)
what is a weakness with using cognitive maps?
the use of heuristics
types of heuristics
right angle bias symmetry heuristic rotation heuristic alignment heuristic relative-position heuristic subjective clusters observation perspective
right angle bias
we tend to represent angles as 90-degree angles
symmetry heuristic
we tend to remember shapes as more symmetrical than they actually are
rotation heuristic
tilted figures tend to be remembered as more vertical or horizontal than they are
alignment heuristic
we tend to represent things more in alignment than they really are
relative-positive heuristic
people use conceptual knowledge affects relative positions
subjective clusters
one’s semantic knowledge affects one’s representations of distances
