Category III: Model construction: (1) Worthy et al. compare predictability between win-stay/lose-shift and Value-Plus-Preservation (VPP) models in the IGT; (2) Steingroever et al. validate the predictive power of the Prospect Valence Learning–Delta model; (3) Dai et al. provide an improved cognitive model for predicting IGT choice behavior; (4) Lin et al. refine a simplified model for estimating IGT performance; and (5) Ahn et al. compare three advanced IGT-related computational models.
