Question 1

Kelly and Brockmole found, when participants judged whether two arrays of lines were the same or different, that:

Accepted Answer

A)  Performance was better when the stimuli were near the hands 
B)  Orientation differences were more easily detected for stimuli near the hands 
C)  Colour differences were more easily detected for stimuli near the hands 
D)  None of these

Question 2

Tau, as an estimate of Time-To-Collision, has been criticised because:

Accepted Answer

A)  There is an error in the mathematics 
B)  It is difficult to apply when an approaching object change shape 
C)  It only works for long distances 
D)  It relies on an accurate estimate of one's own speed

Question 3

Woodworth suggested that the initial stage of a reaching to grasp movement is ballistic. What evidence contradicts this view?

Accepted Answer

A)  Movement slows near the target 
B)  If the target is moved during the reach, the direction of movement is changed appropriately 
C)  A movement can still be made if the target is hidden after the movement has begun 
D)  Appropriate movements can be very fast

Question 4

Prinz's view of actions is that they are controlled by:

Accepted Answer

A)  Perceptual hypotheses 
B)  The recent history of behaviour 
C)  A neural code shared with perception 
D)  Direct pickup of sensory information

Question 5

Patients with optical ataxia cannot:

Accepted Answer

A)  Correct a reaching movement if the target is moved during it 
B)  Judge object size correctly 
C)  Pick up small objects 
D)  Make lateral eye movements

Question 6

In the Material-Weight Illusion:

Accepted Answer

A)  More expensive cloth feels heavier 
B)  Objects with smoother surfaces feel lighter 
C)  When two objects have the same size and mass, which apparently made of a less dense material will feel heavier 
D)  Objects made of lead feel lighter than they really are

Question 7

In Buckingham and Goodale's study, participants lifted a cube which they could not see. Before each lift, they saw either a large or a small cube, whose size biased the apparent weight of the medium cube. This effect shows that:

Accepted Answer

A)  A bottom-up explanation for the Size-Weight Illusion is plausible 
B)  Vision does not influence processing of proprioception 
C)  Proprioception is unreliable 
D)  Participants' expectations play a role in the Size-Weight Illusion.

Question 8

Jeannerod (1981) distinguished two stages in reaching to grasp an object, the 'transport' and the 'grip' components. He suggested that:

Accepted Answer

A)  The transport component is ballistic 
B)  The grip component is governed by the size and shape of the object 
C)  The transport component is modulated by the occipital lobes 
D)  The grip component is programmed before the reach begins

Question 9

Participants of Rushton et al. walked in a curved path towards a target when fitted with prisms which moved the visual scene sideways. The authors suggested that this was because:

Accepted Answer

A)  Optic flow was distorted by the prisms 
B)  Visual direction, but not optic flow, was changed by the prisms 
C)  Walking correctly was harder when the visual field was constricted 
D)  The prisms impaired stereoscopic vision

Question 10

Do perception and motor control use a common code?

Accepted Answer

The answer of Do perception and motor control use a...

Question 11

How does a batter manage to hit a ball?

Accepted Answer

The answer of How does a batter manage to hit...

Question 12

Participants of Brenner et al. hit moving tennis balls with a bat. The experimenters found that:

Accepted Answer

A)  Performance was worse when vision was blurred 
B)  Participants learned to swing the bat a fixed time after the ball first appeared 
C)  Performance was better if the balls were made larger 
D)  Performance depended on the length of time available to view the ball's trajectory

Question 13

Job et al. found, when participants had to judge whether a square target was present in the display, that:

Accepted Answer

A)  Responses were faster to a local target with a power grip 
B)  Responses slower to a local target with a precision grip 
C)  Responses were faster to a global target with a power grip 
D)  Responses were slower to a global target with a power grip

Question 14

How does adjacency to the hand affect visual perception?

Accepted Answer

The answer of How does adjacency to the hand affect...

Question 15

Warren and Hannon showed, using optic flow displays, that:

Accepted Answer

A)  Optic flow governs visual fixation 
B)  Optic flow can be used to judge heading direction 
C)  Optic flow does not change when the fixation point changes 
D)  Optic flow is only useful when driving
