abstract = {Most neuroeconomic research seeks to understand how value
influences decision-making. The influence of reward type is
less well understood. We used functional magnetic resonance
imaging (fMRI) to investigate delay discounting of primary
(i.e., food) and secondary rewards (i.e., money) in 28
healthy, normal-weighted participants (mean age = 26.77; 18
females). To decipher differences in discounting behavior
between reward types, we compared how well-different
option-based statistical models (exponential, hyperbolic
discounting) and attribute-wise heuristic choice models
(intertemporal choice heuristic, dual reasoning and implicit
framework theory, trade-off model) captured the
reward-specific discounting behavior. Contrary to our
hypothesis of different strategies for different rewards, we
observed comparable discounting behavior for money and food
(i.e., exponential discounting). Higher k values for food
discounting suggest that individuals decide more impulsive
if confronted with food. The fMRI revealed that money
discounting was associated with enhanced activity in the
right dorsolateral prefrontal cortex, involved in executive
control; the right dorsal striatum, associated with reward
processing; and the left hippocampus, involved in memory
encoding/retrieval. Food discounting, instead, was
associated with higher activity in the left temporoparietal
junction suggesting social reinforcement of food decisions.
Although our findings do not confirm our hypothesis of
different discounting strategies for different reward types,
they are in line with the notion that reward types have a
significant influence on impulsivity with primary rewards
leading to more impulsive choices.},
