Abstract : Six rhesus monkeys, two males and four females weighing 4.8 to 5.3 kg. were trained to perform four operant tasks (Continuous Avoidance, Response Time Following an Auditory Cue, Response Time Following a Visual Cue and a Fixed Ratio Task). Baseline performance was obtained in the laboratory during a 30-day simulated exposure situation. The exposure phase involved a 10-day pre-exposure baseline, 10 days of continuous exposure to 2r per hour gamma radiation, and a 10-day post-exposure follow-up assessment of performance. A 30-day follow-up was also conducted 60 days following the exposure phase. No performance diminutions were discovered on the aversively motivated tasks, but a performance diminution in the food rewarded fixed ratio task occurred during the radiation exposure. All the animals recovered shortly after the exposure and still appeared normal 8 months later. (Author)
