Table 1.

AICc (Akaike Information Criterion with small sample correction) for exponential and hyperbolic functions in delay and probability discounting, and SP (subjective probability of obtaining delayed rewards)

Exponential Hyperbolic
Delay discounting 92.33 86.49
Probability discounting 90.59 82.33
SP (subjective probability) -6.7 - 14.37

Hyperbolic functions better fit behavioral data in delay and probability discounting and SP. Note that smaller AICc indicates better fitting.
