Factors that affect memory in delayed-matching-to-sample - ANS ✓Nature of
sample stimulus
- some stimuli are easier to remember than others
Duration of exposure to sample stimulus
- longer exposure = better recall
Retention interval between sample and choice task
- longer interval = poorer recall
What is learned in Delayed-Matching-To-Sample? - ANS ✓One rule: choose
same as sample
Multiples rules: if x, then choose x; if y, then choose y; if z, then choose z, etc
Premack (using baby chimps) - ANS ✓Training: delayed-matching-to-sample
with set stimuli
Testing: Used new stimuli (chimp had not seen these presented before)
Predictions:
-If using "same as" rule, then should get answer correct during testing
-if using specific rules, then should not get answer correct during testing
Results: Answered correctly to new stimuli

Radial Arm Maze
- Rats search radial arms in random pattern
- Rats search the radial arm maze in a different pattern every time (no set
strategy)
- Rats do not typically revisit arms that they have already searched (make very
few errors)
Question: How are they searching/solving the maze without making errors?
Phase I: allow rats to only search 4 arms of 8-arm radial maze.
Four-hour delay (rotate maze 90 degrees) - changes spatial location of arms
Phase II: allow rat access to all arms
Predictions:
-If rat is using scent cues to solve the radial arm maze, then it will visit the arms
that it did not visit yet, even though the spatial location of those arms has been
moved
-if rat is using spatial location (cues on the walls) to solve the maze, then it will go
to the arms that are in the spatial location that it has not yet visited (causing it to
revisit arms that were moved to a new spatial location).
Results: Rats go to the spatial location that they had not yet visited.
Memory: Encoding Information (Stimulus Coding) - ANS ✓Definition: The
process of taking information in through your senses and translating it into a
form that your brain can "write down" and store for later use.
Factors that Influence encoding: - ANS ✓Selective Attention - Focusing on a
specific aspect of experience while ignoring others.

Stimuli compete for our attention.
We can only fully attend to one thing at a time
Items compete for our attention (cocktail party effect)
Inattention leads to encoding failure
Levels of Processing - ANS ✓A continuum of memory processing ranging from
shallow processing to deep processing.
Shallow - physical features are analysed
Intermediate - recognition and labeling
Deep - meaningful characteristics; Deep processing leads to better memory.
Elaboration - ANS ✓The "web" of connections, associations, and relevant
meanings given to a stimulus.
Mental Imagery - ANS ✓Creating a mental "story" or scene around stimuli that
we would like to remember.
Dual-code Hypothesis - ANS ✓Memory is stored in two ways: verbal code and
picture code. Mental images are remembered better because it contains both
picture and verbal codes
Imagery in Non-human animals (Gill) - ANS ✓Study by Grill: bitter tastes yuck
face
Conditioned Taste Aversion: Taste-> illness
Taste->yuck face
Imagery in Non-human animals (P. Holland #1) - ANS ✓Phase I:
Tone -> Flavor 1
Noise -> Flavor 2
