Conditioned Inhibition in the spatial domain in humans and rats
Conditioned Inhibition in the spatial domain in humans and rats
Spatial learning has been shown to follow associative rules by demonstrations of blocking and overshadowing in both watermazes with rats and virtual watermazes with humans. To examine whether Conditioned Inhibition (CI) can also be demonstrated in a real and virtual watermaze task, two studies were run, one with rats and one with humans. In separate training trials Beacons A and B marked the position of a platform in quadrant X of circular watermaze (AX +/BX+). In subsequent inhibitory training trials, Beacon A was placed in quadrant Y with no platform present (AY-). To test for any CI of Y, in 2 probe trials B was suspended above either quadrant Y (BY) or novel quadrant Z (BZ). Time spent under B was recorded in both trials. In both animal and human studies, during no platform probe trials, latencies to reach Beacon B were longer and less time was spent under the beacon when it was suspended in quadrant Y, where inhibitory training had previously taken place (AY- trials), than when it was hung in the novel quadrant Z. Results suggest that quadrant Y had become a conditioned inhibitor strengthening claims that learning in the spatial domain follows the rules of associative models.

Abstract
Spatial learning has been shown to follow associative rules by demonstrations of blocking and overshadowing in both watermazes with rats and virtual watermazes with humans. To examine whether Conditioned Inhibition (CI) can also be demonstrated in a real and virtual watermaze task, two studies were run, one with rats and one with humans. In separate training trials Beacons A and B marked the position of a platform in quadrant X of circular watermaze (AX +/BX+). In subsequent inhibitory training trials, Beacon A was placed in quadrant Y with no platform present (AY-). To test for any CI of Y, in 2 probe trials B was suspended above either quadrant Y (BY) or novel quadrant Z (BZ). Time spent under B was recorded in both trials. In both animal and human studies, during no platform probe trials, latencies to reach Beacon B were longer and less time was spent under the beacon when it was suspended in quadrant Y, where inhibitory training had previously taken place (AY- trials), than when it was hung in the novel quadrant Z. Results suggest that quadrant Y had become a conditioned inhibitor strengthening claims that learning in the spatial domain follows the rules of associative models.
