1. Dopaminergic firing is correlated _________ to the magnitude of the reward.

a) positively; as the size of the reward increases, so does the firing rate

b) negatively; as the size of the reward increases, the firing rate decreases

c) positively and negatively; depending on the type of reward, the firing rate may increase or decrease with an increase in the reward size

d) none of the above; there is no correlation between reward magnitude and dopaminergic firing

Please explain

2. What is the formula of the prediction error (PE)?

a) PE = learning rate * reward occurred

b) PE = reward occurred – reward (at t-1)

c) PE = reward occurred – reward expected

d) PE = reward occurred – reward of unchosen option
