Articulatory rehearsal loop (not on study guide) *(Ch.1)*
Correct Answers The articulatory rehearsal loop has two
elements:
*subvocalization*—silently pronouncing words
*a phonological buffer*—memory store of sound of words, last
1-2 seconds
Be able to differentiate between the "what" and the "where"
visual pathways/systems. *(Ch. 3 & 4)* Correct Answers o
*Signals from the occipital lobe go to one of two places*:
1. *the temporal lobe*, where object recognition (and face
recognition) appears to happen,
2. *the parietal lobe*, where location seems to be computed.
- *The "WHAT" visual pathway refers to the path the signals
take towards the temporal lobe, and the "where" visual pathway
if for the path towards the parietal lobe.*
--Identification of objects
--Involves an Occipital-temporal pathway
--Damage could produce visual agnosia
- *The "WHERE" system is also called the "HOW" system,
because it's important for acting on things in space, such as
picking up pencil.*
--Is concerned with determining the locations of objects and
guiding our actions in response
--Involves an occipital-parietal pathway
,--Damage to this system can result in problems with reaching for
seen objects
Be able to explain *how multiple areas of brain contribute to
cognitive processing*, even in what appears to be single task.
*(Ch.2)* Correct Answers Lesions result from brain damage
and have specific effects. Damage to the left side of the frontal
lobe, for example, is likely to produce a disruption of language
use; damage to the right side of the frontal lobe does not have
this effect.
Be able to explain the new neural network model introduced,
where activation can flow from bottom to higher levels, and vice
versa (from higher levels to lower levels). *(Ch. 3 & 4)*
Correct Answers -A much more complex feature net
-More like a brain
-Links between nodes can be excitatory or inhibitory
-Activation goes both directions bottom-up and top-down
only seeing the bottom part of an O
Bottom-up processing *(Ch. 3 & 4)* Correct Answers
Stimulus-driven effects
Codes about spatial positions *(Ch. 3 & 4)* ?? Correct Answers
- *Spatial position*—the visual areas processing features like
shape, color, and motion each know the spatial position of the
object.
, Do specialized cognitive resources exist for certain tasks? &
provide an example and what that sample suggests *(Ch. 5)*
Correct Answers - Some combinations of tasks more difficult to
do, EVEN if there are enough general cognitive resources to
cover them. *This suggests that specialized cognitive resources
exist for certain tasks.*
*EXAMPLE*
*A study by Allport, Antonis, and Reynolds (1972)
demonstrated the following:*
People suck at shadowing (repeating back) a list auditory words
while simultaneously hearing a second list of different auditory
words
They shadow auditory words a little better when they saw the
words from a different list instead
They shadow auditory words even better when they looked at
pictures instead of words.
This *SUGGESTS that there are specific resources being used*:
resources for LISTENING and resources for LOOKING AND
VIEWING. There also appear to be resources for *dealing with
words and for dealing with pictures.*
Explain excitatory versus inhibitory connections between nodes.
How can this account for word superiority effect? *(Ch. 3 & 4)*

Explain Posner's three attentional networks: Alerting, Orienting,
and Executive Control. *(Ch. 5)* Correct Answers *Alertness*
