Q

Action for Vision

A
  • Viewer actively searches for only part of the target object and attends selectively to it
  • Tend to scan more of the left visual field when looking at faces

Q

Associative Agnosia

A

inability to recognize object despite its apparent perception

21
Q

Prospagnosia

A

cannot recognize previously known faces, including their own as seen in a mirror or photograph

22
Q

Alexia

A

an inability to read has often been regarded a symptom complementary to facial-recognition deficits. Alexia is most likely to result from damage to the left fusiform and lingual areas

23
Q

Visuospatial Agnosia

A

The inability to find one’s way around familiar environments such as one’s neighborhood

24
Q

Postcentral gyrus (Brodmann’s area 1,2,3)

A

close to the motor cortex around the superior boundary of the Parietal and Frontal Lobe

25
Q

Superior parietal lobule (area 5 and 7)

A

The parietal lobe (superior position)

26
Q

Parietal operculum (area 43)

A

around the high point of the Sylvian Fissure

27
Q

Supramarginal gyrus (area 40) and angular gyrus (39)

A

Follows the dorsal pathway

28
Q

Regions of intraparietal sulcus

A

tribute to control of saccadic eye movements (area LIP) and visual control of object-directed grasping (AIP

29
Q

Theory of Parietal-Lobe Function

A

Anterior zone processes somatic sensations and perceptions
Posterior Zone is specialized primarily for integrating sensory input from somatic and visual regions and, to a lesser extent, from other sensory regions, are mostly for the control of movement

30
Q

topographical knowledge

A

Representations of space vary from simple ones, which are applicable to the control of simple movements to abstract ones (topographical knowledge)

31
Q

Frontal Lobe

A
  • Frontal association area
  • Speech
  • Motor cortex
32
Q

Parietal Lobe

A
  • Somatosensory cortex
  • Taste • Speech
  • Reading
  • Somatosensory association area
33
Q

Temporal Lobe

A

• Smell • Hearing

Auditory Association area

34
Q

Occipital Lobe

A

• Visual association area

Vision

35
Q

Spatial Information

A
  • Direct Actions at Objects
36
Q

Object Recognition

A
  • Objected-centered system must be concerned with size, shape, color, and relative location
  • Being able to recognize objects when in diff. vantage points (rely on memory)
37
Q

sensorimotor transformation

A

Intergrating the movements of diff. body parts with the sensory feedback of what movements are actually being made and the plans to make movement

38
Q

Sensorimotor Integration

A

Experiencing the world through our body map

39
Q

Posterior parietal lobe

A

controls visuomotor guidance of movements in egocentric space

40
Q

Premotor Cortex

A

Whereas motor cortex provides mechanism for executive individual movements ; premotor selects movements to be executed

41
Q

Prefrontal Cortex

A

Motor cortex makes movement, premotor selects, and prefrontal controls cognitive processes

42
Q

Internal cues

A

temporal memory guides selection

•Related to movements that are derived from object-recognition (motor streams) of sensory processing

43
Q

External cues

A

associative learning (orbitofrontal cortex) ….

44
Q

Context cues

A

behavior that is appropriate at one movement might not be if context changes

45
Q

Autonoetic Awareness

A

Autobiographic knowledge

46
Q

Voluntary Gaze

A

problems with directing gaze. Tend to gaze over picture at random

47
Q

Self-regulation

A

deficits in regulation own behavior ( loss of autonoetic awareness)

48
Q

Response Inhibition

A

Perseverate on responses in variety of test situations, particularly those with changing demands
