Q

what is the difference between direct modelling and vicarious conditioning?

A

direct modelling involves mimicking other’s actions/responses, whereas vicarious learning involves you to see the consequences of such actions and you do the actions depending on whether or not the consequences were good (more likely to do it too) or bad (less likely to do it)

Q

What leads to better recall? Verbal sounds, written words, or pictures? why?

A

Pictures because they utilize more than one mode of encoding the memory/mental representation.
They elicit both, visual modes of representation and verbal, words, “semantic” representations too (The “story of the picture”), which gives us more memory “hooks”/neural pathways/inroads/cues for later retrieval

Q

what does long term potentiation refer to?

A

the idea that firing neurons together while studying or teaching others the material, over and over makes them wire together, and thus more likely to fire together when you try to recall the information later on

137
Q

what might be the cause of run of the mill forgetting?

A

Forgetting clears out redundant, unimportant items, unused neural pathways get taken over for other purposes, before these memories even have a chance to become consolidated
Or
Sometimes we “forget things” due to absent-mindedness, we just don’t pay attention, get distracted, and fail to encode the info in the first place

A

when previously learned information interferes with newer memories
ex: speaking a second language, remembering old passwords but not new ones, relearning how to play an instrument that you taught yourself to play

143
Q

what is retroactive interference? examples?

A

the material we learned later (newer) muddles up our memory for what we learned earlier (older)
ex: only remembering unreal lyrics and not the actual lyrics

161
Q

what does the psychometric approach look at in terms of IQ?

A

Looks at the items on the IQ tests and tries to figure out what the related components of intelligence are based on the products of these tests, the actual answers people give, and their “scores”; uses a sophisticated statistical tool called “factor analysis” to ferret out the different components of the IQ tasks and see how they correlate to one another to form “clusters”

162

what are the 2 theories proposed to explain deja vu?

A

the delayed perception theory, and the cognitive theories

209
Q

what is delayed perception theory?

A

visual information comes in through 2 pathways; the conscious “what” pathway, and the unconscious “where” pathway. Any glitch can cause us to perceive the scene as already having happened

210
Q

what part of the brain is key to the delayed perception theory? what is that part of the brain responsible for?

A

parahippocampal gyrus: which distinguishes between familiar & unfamiliar stimuli without having to access explicit LTM

211
Q

what is the cognitive theories for deja vu?

A

Long-forgotten implicit memories trigger déjà vu, or perhaps even aspects of the old forgotten memory can trigger déjà vu
OR
2) Attention & working memory
Perhaps we have just taken in the scene via sensory memory but it has not become conscious, and then a second later we “notice” an element of it & déjà vu ensues

212
Q

what is chronobiology?

A

The study of how time of day (month, year) impacts our physical functions and responses to treatments. We study this so we can find best ways to synchronize medications, and other treatments (including surgery) to work better with the body’s natural rhythms

Q

what types of sleepers and are likely to be drowsy drivers?

A

226
Q

what do we know sleep ISNT for?

A

Sleep isn’t needed to re energize the body because the body can get as much of a recharge from meditation or a quiet rest
Sleep isn’t for letting our bran rest because the brain can be just as active during sleep as when we’re awake

227
Q

what do we THINK sleep is for?

A

Consolidation of memories, organization and processing of the day’s events,
Making new associations, new neural connections, new pathways between old info and new

228
Q

what is synaptic homeostasis?

A

while awake, we reactivate neuronal circuits to reinforce memory links. But the same spontaneous firing during sleep may weaken the synapses, between neurons in many roused circuits, which returns the synapses to a baseline level of strength in order to conserve energy in, and reduce stress on nerve cells.

This might be because the brain is primed to make all kinds of connections in REM sleep because it is a highly “associative” state,
