25
Q

visual pathway in which most neurons respond most robustly to the characteristics of objects, such as color and shape

A

ventral stream

26
Q

visual pathway in which there are clusters of neurons which each respond specifically to a particular class of objects, such as faces, bodies, letters, animals, or tools

A

ventral stream

27

A

ventral stream

31
Q

phenomenon that is displayed by patients with areas of blindness (scotomas) resulting from damage to the primary visual cortex

A

blindsight

32
Q

is the ability to respond to a visual stimulus in an area of blindness (scotoma) despite having no conscious awareness of the stimulus

A

blindsight

33
Q

is the phenomenon in which a subject might reach out and grab a moving object in her area of blindness, all the while claiming not to see it

A

blindsight

34
Q

with what disorder would a patient deny seeing objects in his right visual field

A

blindsight

35
Q

is a failure to recognize faces that is not attributable to a sensory deficit or to verbal or intellectual impairment

A

prosopagnosia

36
Q

phenomenon that causes patients to recognize a face as a face but have problems recognizing whose face it is

A

37
Q

phenomenon that causes patients to see a face as a jumble of individual facial parts (e.g., eyes, nose, chin, cheeks) that are never fused into an easy-to-recognize whole

A

propsopagnosia

phenomenon that results from damage to the ventral stream in the area of the boundary between the occipital and temporal lobes known as the fusiform face area

Q

is the phenomenon in which a subject can see a visual stimulus but not know what it is

visual agnosia

41
Q

phenomenon that can be restricted to recognition of a particular aspect of visual input (e.g., movement or color) as a result of damage to an area of secondary visual cortex that mediates the recognition of that particular attribute

Q

phenomenon that affects only the left side of the environment and results from extensive damage to the right posterior parietal lobe

contralateral neglect

52
Q

is the phenomenon in which we consciously perceive only a small subset of the many stimuli that excite our sensory organs at any one time and largely ignore the rest

A

selective attention

53
Q

phenomenon that has 2 characteristics: it improves the perception of the stimuli that are its focus, and it interferes with the perception of the stimuli that are not its focus

A

selective attention

54
Q

phenomenon that occurs if by focusing your awareness on an announcement in a noisy airport your chances of understanding it increase but decrease for that of a simultaneous comment

A

selective attention

55
Q

phenomenon that is thought to work by strengthening the neural responses to attended-to aspects and by weakening the responses to others

A

selective attention

56
Q

phenomenon that is occurring if a subject fails to notice that a picture hanging on the wall is only present in one of two otherwise identical photographs

A

change blindness

57
Q
  • is a difficulty perceiving major changes to unattended-to parts of a visual image when the changes are introduced during brief interruptions in the presentation of the image

change blindness
