Abstract

When a cue is established as a reliable predictor of an outcome (A–O1), this cue will typically blocklearning between an additional cue and the same outcome if both cues are subsequently trained together(AB–O1). Three experiments sought to explore whether this effect extends to outcomes and wasinves...
