“…Latency data from nine experiments show a fundamental similarity to a discrete· trials instrumental escape·conditioning model in demo onstrating replicable analogs of (1) acquisition, (2) ex· tinction, (3) partial·reinforcement effects, (4) drive effects, (5) a delay of reinforcement gradient, (6) cor· related reinforcement effects, (7) correlated delay of reinforcement effects, and (8) intermittent shock effects (Weiss, Beck, & Stich, 1972;Weiss, Boyer, Colwick, & Moran, 1971;Weiss, Lombardo, Warren, & Kelley, 1971;Weiss, Williams, & Miller, 1972).
