Overview

Behavioral experiment demonstrates operant conditioning and reversal learning in corn snakes, suggesting advanced behavioral flexibility and long-term memory comparable to other vertebrates.

Key Points

To assess operant conditioning, behavioral flexibility through serial reversal learning, and long-term memory retention in corn snakes using olfactory and visual cues.
Trained 15 corn snakes (Pantherophis guttatus) across two cohorts to discriminate between paired olfactory and visual stimuli using food reinforcement.
Evaluated learning using an acquisition criterion of at least seven consecutive correct choices, followed by serial reversal trials and memory tests at three and six months.
Cohort 1 showed significant reductions in error rates and choice latencies, requiring progressively fewer trials to reach criterion during successive reversals.
Cohort 1 retained memory of reinforced visual cues with a 95% accuracy rate six months post-experiment, whereas cohort 2 exhibited random choice performance at three months.
