Asymmetries in cue competition in forward and backward blocking designs : Further evidence for causal model theory

摘要: A hallmark feature of elemental associative learning theories is that multiple cues compete for strength when presented with an outcome. Cue competition effects have been observed in humans, both forward and backward blocking procedures (e.g., Shanks, 1985) are often interpreted as evidence account human causal Shanks & Dickinson, 1987). Waldmann Holyoak (1992), however, demonstrated cue only occurs predictive, not diagnostic, paradigms. While unexplainable from perspective, this asymmetry readily follows structural considerations model theory. In paper, we show models determine the extent but also designs. Implications inferential accounts discussed.
