Table 2 Key features of fitted theoretical models

From: Biased expectations about future choice options predict sequential economic decisions

Model name

Free parameters

Strategy

Cut Off heuristic

Cut off, Softmax beta

Chooses no option until after a “cut off” number of samples, then chooses next option with highest relative rank.

Cost to Sample

Cost to sample, Softmax beta

Ideal Observer, but sampling can be perceived as costly.

Biased Values

Option value threshold, Softmax beta

Ideal Observer, but only option values above a threshold can be considered.

Biased Prior

Constant added to prior mean, Softmax beta

Ideal Observer, but expected value (mean) of prior option value distribution can be reduced by a constant.
