Table 1. Goodness-of-fit Estimates from Computational Models on Cognitive Effort Levels.

	Linear	Exponential	Parabolic	Hyperbolic
AIC	1223.32	1245.43	1170.66	1293.65

Note. Separate models were fit for each mathematical function on participants’ data; AIC = Akaike Information Criterion (Akaike, 1974).
