False
Sensory memory can be prolonged by active rehearsal.
True or False
False
Which of the following is characteristic of sensory memory?

What is the main issue with oculomotor delayed response task?
a) It conflates short term memory with motor preparation
b) It conflates short term memory with attention
c) It conflates short term memory with visuo-spatial processing

a) It conflates short term memory with motor preparation.
Slot models of working memory encode contents in all or nothing fashion.
True or False
True
Contents of episodic memory are stored in the hippocampus even after memory consolidation.
False
What of the following was observed in patient HM?
a) He did not have any anterograde amnesia
b) He couldn’t form procedural memory
c) His working memory was functioning
c) His working memory was functioning
Contents of working memory are believed to be stored in a…
distributed manner in the neocortex
In Sperlings iconic memory test, theoretical availability of recall is lower than whole report accuracy.
True or False
False
12) Which of the example is an example of non-declarative memory?
a) Semantic memory
b) Episodic memory
c) Procedural memory
d) Working memory
c) Procedural memory
Perceptual priming is an example of declarative memory:
True or False
False
Declarative memory is hippocampus dependent – in contrast with non-declarative memory.
True or False
True
Memory traces in long term storage cannot decay.
True or False
False
Memory is consolidated in long term storage though the process of
a) Long term potentiation
b) Neurogenesis
c) Network structuring
d) Short term potentiation
a) Long term potentiation
Patients with hippocampal lesions will remember more recent events better than very distant ones.
True or False
False
Procedural memory is basely dependent on
a) Neocortex
b) Reflex pathways
c) Hippocampus
d) Basal ganglia
d) Basal ganglia
Mesolimbic and mesocortical pathways originate in Substantia Nigra.
True or False
False
Medial orbitofrontal cortex shows increasing activity with increasing reward.
True
Which of the following is not true of orbitofrontal cortex?
a) It is a projection zone of dopaminergic neurons
b) It is a point of multimodal convergence
c) It synthesizes dopamine
d) It represents value of reward
c) It synthesizes dopamine
In reward prediction error approach, dopaminergic neurons do not burst at:
predicted reward
Temporal discounting is a preference to select small but immediate reward over a larger but delayed one.
True or False
True
What is a correct definition of PFC?
The part of frontal cortex that does not elicit movement when stimulated
Which structure is relevant for error detection and resolution of conflicts?
Anterior Cingulate Cortex (ACC)
In incentive salience approach of dopaminergic system, dopamine mediates only the liking component of reward
False
Premotor Cortex (BA 6) is a part of prefrontal cortex.
True or False
False
The premotor cortex, also known as Brodmann area 6, is not considered to be a part of the prefrontal cortex (PFC).
The premotor cortex is located in the frontal lobes of the brain, just anterior to the primary motor cortex. It is involved in the planning and execution of movement, as well as in the control of attention and perception during movement.
The relative size of PFC is highest in humans across all animals
True or False
False
Great apes such as chimpanzees and orangutans have a PFC that is larger relative to the rest of the brain than in humans.
Which of the following is not a consequence of PFC lesions?
a) perseveration errors
b) deterioration of IQ
c) deficiency in foresight and planning
d) loss of spontaneity
b) deterioration of IQ
What is a neuropsychological test for perseveration?
Wisconsin Card Task
In Stroop task, people are fast at reading words, but slow at naming colours.
True or False
True
Anterior cingulate cortex is a part of neocortex.
True or False
False
A stimulus whose removal encourages (reinforces) certain behavior is called:
negative reinforcer
Dopamine mediates only liking component of reward
True or False
False
Dopamin is involved in both the liking and wanting components of reward.
