Question 7

______________ tuning is determined by whether a delay is built into the transmission of signals from Neuron 1 and Neuron 2,while tuning is determined by the length of the delay.

Accepted Answer

A) Direction;speed 
B) Speed;direction 
C) Linear;curvilinear

Question 8

The neural circuit to explain motion aftereffects would require that the ML neuron______________ while the MR neuron .

Accepted Answer

A) responds strongly;fires at its baseline rate 
B) responds weakly;fires at its baseline rate 
C) receive no stimulation;receives some stimulation

Question 9

Recent films such as Avatar and The Hobbit have blended human acting with computer ani- mation.Using the "motion-capture" technique,actors perform while wearing suits that have strategically placed spots (i.e,at the joints).The recorded performance is later translated into animation by maintaining the key spatial and temporal relationships from the original to the animation.How is this technique related to the study of perception from biological motion?

Accepted Answer

The answer of Recent films such as Avatar and The...

Question 10

Beckers and Zeki (1995)used transcranial stimulation to temporarily deactivate area MT during the presentation of a moving-dot stimulus and found that the perception of

Accepted Answer

A) motion was impaired. 
B) motion was unaffected. 
C) color was enhanced.

Question 11

The parietal lobe is divided into the parietal lobe and the parietal lobe by the sulcus.

Accepted Answer

A) anterior;posterior;postcentral 
B) anterior;posterior;central 
C) superior;inferior;intraparietal

Question 12

A rising fastball

Accepted Answer

A) occurs only when a pitch actually exceeds 100 mph. 
B) is an illusion caused by the lack of spin with a knuckleball. 
C) is an illusion caused by the batters incorrect underestimation of the speed of the pitch.

Question 13

The eye movements that you use when you read are called eye movements.

Accepted Answer

A) saccadic 
B) smooth pursuit 
C) vergence

Question 14

Lakshmi is standing,facing forward,on a crowded train that has come to a station and stopped.There is also a stopped train on an adjacent track.Suddenly,the train on the adjacent track begins to move backward (relative to Lakshmi's train).When Lakshmi sees the adjacent train,what is she likely to perceive,and how will she physically respond to what she perceives?

Accepted Answer

The answer of Lakshmi is standing,facing forward,on a crowded train...

Question 15

Newsome et al.(1989)used the coherence of motion technique to study monkeys' perception of motion.When comparing the results of single-cell recordings from area MT with the monkeys' judgments they found that

Accepted Answer

A) the judgments were about what one would expect if the judgments were based on the re- sponses of the population of MT neurons. 
B) the judgments were about what one would expect if the judgments were based on the re- sponses of the population of V1 neurons. 
C) the judgments were inconsistent with what one would expect if the judgments were based on the responses of the population of MT neurons.

Question 16

Place your index finger on the far outside edge of one of your eyelids.Now apply gentle pres- sure to your eye (through the lid;do not touch your eye directly).As you apply pressure,you should see your environment tilt in correspondence with your eye's movement.(A)How would you explain the perception of movement as your eye moves? (B)Does this demonstration sup- port the corollary discharge signal as the stabilizing mechanism during eye movement?

Accepted Answer

The answer of Place your index finger on the far...

Question 17

Sommer and Wurz (2006)trained monkeys to make a saccade from an initial fixation point (FP1)to a later fixation point (FP2).They recorded from single cells in the frontal eye field of monkeys,and their findings offered support for the importance of the corollary discharge signal (CDS),since a flash of light to the

B) future field (FF)led to a strong response after the saccade. 
C) future field (FF)led to a strong response just before the saccade.
