“…Briefly, the chamber was an approximately 2.3m square room with two back projection screens, 2 response devices (Elsberry, 1972), and a retractable food hopper (Sandler et al, 1971) on the front wall ( Figure 3). Rein forcements throughout the training and testing period consisted of the food hopper in the test chamber swinging up to make a small portion of cracked corn available to the animal being tested, A constant level of white noise was maintained in the chamber through a loudspeaker on the ceiling.…”

Seven squirrel monkeys were systematically exposed to dieldrin (C12H10DC16) at two oral doses: 0.10 and 0.01 mg/kg-day. Two zero-dose controls were included. After 55 days of exposure dose assignments were shifted and continued for an additional 54 days. The higher dose group was shifted to zero exposure and lower dose group was shifted to high-dose exposure. Controls continued at zero exposure. The monkeys were presented with a visual nonspatial successive discrimination reversal task. During the first 55 days (preshift), control and low-dose monkeys learned the task; high-dose monkeys did not (p less than 0.001). During the subsequent 54 days (postshift), all groups performances remained at the approximate level achieved at the end of the preshift period. It was concluded that the high dose disrupted learning acquisition. This effect is speculated to be attributed to disruption of hippocampal activity. The low dose had no effect on task acquisition or maintenance.
