Question 4
Which of the following statements does correctly describe the role of the LIP neurons in perceptual decisions?
Your Answer Score Explanation
The LIP neurons are motion sensitive neurons that send information to the brain
area MT
The LIP neurons are motion sensitive neurons. The likelihood that the monkey
would make a rightward saccade is a lawful function of the firing rate of the rightward
motion–preferring neurons in area LIP
The LIP neurons accumulate (motion-related) information over time till a decision
threshold. Importantly, electrical stimulation of the LIP neurons affects decisions

Question 9
Which of the following is the Iowa Gambling Task?
Your Answer Score Explanation
Participants are presented with 4 decks of cards. Every card drawn will earn the
participant a reward. Occasionally, a card will also have a penalty. Thus, some decks
are "bad decks", and other decks are "good decks", because some will lead to losses
over the long run, and others will lead to gains
Initially, a number of stimulus cards are presented to the participant. The
participant is told to match the cards, but not how to match; however, he or she is told
whether a particular match is right or wrong.

The first player proposes how to divide the sum between the two players, and the
second player can either accept or reject this proposal. If the second player rejects,
neither player receives anything. If the second player accepts, the money is split
according to the proposal. The game is played only once so that reciprocation is not
an issue
