One-Trial Learning and Biphasic Time Course of Performance in the Goldfish

One-Trial Learning and Biphasic Time Course of Performance in the Goldfish

Goldfish (N = 408) spontaneously swam against flowing water into a calm-water well. After a single trial punished by brief electric shock, the fish avoided the well, as indexed by increased latencies of reentry. Avoidance declined during the first minute after shock, then rose to a peak 1 hour later...

Zusammenfassung:Goldfish (N = 408) spontaneously swam against flowing water into a calm-water well. After a single trial punished by brief electric shock, the fish avoided the well, as indexed by increased latencies of reentry. Avoidance declined during the first minute after shock, then rose to a peak 1 hour later. The biphasic time course is compatible with the two-store theory of memory formation.
