Conducted a series of experiments with object-discrimination learning-set (ODLS) experienced blue jays. Exp. I demonstrated long-term retention of the ability to solve new ODLS problems, short-term retention loss of intraproblem information concerning specific problems after 2 acquisition trials, and a higher percentage correct following a reinforced Trial 1 response than following a nonreinforced Trial 1 response. Exp. II demonstrated that this Trial 1 outcome effect could be reversed with single-object Trial 1 procedures. Exp. III showed that when intraproblem retention testing was carried out later in each problem, after 5 acquisition trials, with a single-object Trial 1 procedure, the differential effect of Trial 1 outcome was eliminated. Exp. IV demonstrated that replacement of the stimulus chosen on Trial 1 disrupted Trial 2 performance, while replacement of the nonchosen object had no effect. Results are interpreted as consistent with a response-strategy view of the ODLS behavior of the blue jay similar to that based on research with macaque monkeys. (20 ref.)
