Corpus Callosum
24
Q
A
Corpus Callosum
25
Q
- phenomenon that results from the corpus callosum being severed
A
Split-Brain
26
Q
- phenomenon that occurs if patients have their left and right cerebral hemispheres separated
A
Split-Brain
27
Q
- phenomenon that would cause a patient, who had a test object flashed in the left visual field, to say that nothing appeared on the screen and to be able to identify the correct object with the left hand but not with the right hand
A
Split-Brain
28
Q
- phenomenon that would cause a patient, who had two different test objects flashed in the left vs. the right visual fields, to be able to simultaneously reach into two bags and grasp both of the correct objects, with one object in each hand
A
Split-Brain
29
Q
- phenomenon that would allow each cerebral hemisphere to be able to maintain an independent focus of attention
A
Split-Brain
30
Q
- phenomenon that would cause a patient to search and identify a visual target item in an array of similar items more quickly than a healthy control could
A
Split-Brain
31
Q
- is nonneural communication between cerebral hemispheres that have been separated by commissurotomy
A
Cross-Cuing
32
Q
- is the phenomenon in which a subject, who had a test object visually flashed to just the right cerebral hemisphere, could have the left cerebral hemisphere identify the correct object due to the right hemisphere initiating a frown or shaking the head, no, each time the left hemisphere made an incorrect guess
A
Cross-Cuing
33
Q
- is the redirection of one hand of a split-brain patient by the other hand
A
Helping-Hand
34
Q
- is the phenomenon in which a subject, who had a test object flashed in the left visual field, could have the right hand identify the correct object due to the left hand grabbing the right hand away from incorrect objects and redirecting it to the correct object
A
Helping-Hand
35
Q
- is a hypothetical mechanism that is assumed to reside in the left cerebral hemisphere and that continuously assesses patterns of events and tries to make sense of them
A
Interpreter
36
Q
- is the phenomenon in which a subject, who has been asked to predict whether a light will appear on the top or the bottom of a computer screen on a series of trials, attempts to find deeper meaning and so distributes responses between the two alternatives according to the probability that each will occur, despite the fact that the optimal strategy would simply be to consistently choose the more probable alternative (e.g., always selecting the top light)
A
Interpreter
37
Q
- is an area of temporal cortex that lies posterior to the primary auditory cortex and, in the left hemisphere, roughly corresponds to Wernicke’s area
A
Planum Temporale
38
Q
- forebrain structure that tends to show greater leftward asymmetry in musicians with perfect pitch (the ability to identify the pitch of individual musical notes) than in nonmusicians or in musicians without perfect pitch
A
Planum Temporale
39
Q
A
Broca’s Area
40
Q
- forebrain structure that is located in the inferior portion of the left prefrontal cortex and has a speech production function
A
Broca’s Area
41
Q
- according to the Wernicke-Geschwind model, selective damage to this brain structure produces an aphasia disorder characterized by speech that retains its meaningfulness despite being slow, labored, disjointed, and poorly articulated
A
Broca’s Area
42
Q
A
Wernicke’s Area
43
Q
- according to the Wernicke-Geschwind model, selective damage to this brain structure produces an aphasia disorder characterized by poor comprehension of language and speech that is meaningless but still retains normal structure
A
Wernicke’s Area
44
Q
- forebrain structure that is located in the posterior region of the lateral fissure in the left temporal lobe and has a language comprehension function
A
Wernicke’s Area
45
Q
- forebrain structure that is the major neural pathway between Broca’s area and Wernicke’s area
A
Arcuate Fasciculus
46
Q
- according to the Wernicke-Geschwind model, selective damage to this forebrain structure produces an aphasia disorder characterized by largely intact comprehension of language and spontaneous speech but difficulty repeating words just heard
A
Arcuate Fasciculus
47
Q
- forebrain structure that is located in the posterior cortex at the boundary between the temporal and parietal lobes, which in the left cerebral hemisphere is thought to play a role in reading
A
Angular Gyrus
48
Q
- according to the Wernicke-Geschwind model, selective damage to this forebrain structure produces the inability to read (alexia) and the inability to write (agraphia)
A
Angular Gyrus
