Front 24

What is Capgras delusion? Describe the symptoms of Capgras and ramachandran's thoery of why it occurs. How did he test this theory? What was the outcome?

Back 24

he thinks his own parents are imposters. the theory is that the pathway wasn't connected to the amygdala

Front 25

two types of long-term memory?

Back 25

explicit, implicit

Front 26

episodic memory

Back 26

for events

Front 27

semantic memory

Back 27

Front 28

explicit is?

Back 28

things we're aware of

Front 29

implicit is?

Back 29

things we're less aware of

Front 30

what is korsakoff's syndrome? describe some of the symptoms seen in the case study 'the lost mariner'

Back 30

when you drink too much alcohol for a long period of time you become amnesiac. You lose insight, have confabulation and temporal memory problems (inability to form memories).

Front 31

in the video on the capgras delusion, ramachandran hypothesized that the temporal lobe was cut off from the ____?

Back 31

amygdala

Front 32

in order to test the hypothesis in the capgras case, ramachandran showed the patient david pictures of his mother and monitored his:

Back 32

skin conductance response

Front 33

in the video in class, the woman who could not see the motion of the train coming toward her had damage to which visual area?

Back 33

MT

Front 34

briefly describe one type of synesthesia:

Back 34

being able to see music as colors

Front 35

Billy told you that he has synesthesia because he associates the number 2 with the color green on some days and the color purple on other days. You told him that he probalby doesn't have synesthesia because:

Back 35

the colors stay consisten and don't really vary

Front 36

true or false: the visual system works in such a way that one area in the brain processes all of the visual information

Back 36

false

Front 37

Basic memory processes?

Back 37

encoding, storage, and retrieval

Front 38

Endoding is

Back 38

information coded into memory

Front 39

storage memory process is

Back 39

when you retain information over time

Front 40

retrieval memory process is

Back 40

getting information back

Front 41

short-term memory:

Back 41

memory for information currently 'in mind'; limited capacity

Front 42

working memory

Back 42

working memory

Front 43

long term memory

Back 43

stored information that needs not be presently accessed or even consciously accessible; has virtually unlimited capacity

Front 44

Plasticity is:

Back 44

the brain's ability to change as a result of experience

what is related in The Lost Mariner stroy?

Back 46

Sensation is when sensory receptors receive stimulus energies from our environment

perception is the process of integrating, organizing and interpeting sensory information

Front 47

What is the role of the retina in vision?

Back 47

Lght passes through the pupil & lens and is focused on the retina, then receptors in the retina (rods, cones) convert that light into neural signal
