Q

Response to the observed action ‘___’ the response of what happens when the monkey ___ ____ ___, diminished/little response if object grasped ____ ____ like by pliers

A

Response to the observed action ‘mirrors’ the response of what happens when the monkey grasps something themselves, diminished/little response if object grasped less directly like by pliers

Q

motion is also a cue that we rely on for distinguishing between __ __

A

motion is also a cue that we rely on for distinguishing between event boundaries

17
Q

akinetopsia

A

an inability to perceive motion

18
Q

real motion

A

occurs when an object is physically moving

19
Q

Illusory motion aka apparent motion, phi phenomenon

A

stationary stimuli are presented in slightly different locations, perceive motion but there is no motion

20
Q

induced motion

A

movement of one object (usually a larger object e.g. clouds) results in the perception of movement in another object (usually a smaller object e.g. the moon)

21
Q

Motion aftereffect

A

observer looks at movement of object for 30-60 seconds, then a stationary object, and movement appears to occur in opposite direction from original movement

22
Q

Motion aftereffect relates to ___ (adapting) neurons tuned to motion in one direction, which become ___ sensitive compared to neurons tuned to motion in other directions ( a relative difference that your system interprets as ____)

A

Motion aftereffect relates to fatiguing (adapting) neurons tuned to motion in one direction, which become less sensitive compared to neurons tuned to motion in other directions ( a relative difference that your system interprets as motion)

23
Q

Larsen et al. scanned participants using fMRI while viewing 1 of 3 displays.. which were ..

A

control condition, real motion condition, apparent motion condition

24
Q

Control condition

A

2 squares in slightly different positions are briefly presented simultaneously, each square activated a separate area of the visual cortex

25
Q

Real motion condition

A

a small square is moved back and forth

26
Q

Apparent motion condition

A

2 squares are quickly alternated on alternate sides of the display so as to create illusory motion

27
Q

Perception of motion in both cases (apparent and real) involve ___ ___ mechanisms

A

Perception of motion in both cases (apparent and real) involve similar neural mechanisms
