A theory of attending and reinforcement in conditional discriminations (Nevin, Davison, & Shahan, 2005) is extended to working memory in delayed matching to sample by adding terms for disruption of attending during the retention interval. Like its predecessor, the theory assumes that reinforcers and disruptors affect the independent probabilities…
