Learning is a vital cognitive based process that supports memory retention at short- and long- term intervals. This process is highly volatile and can get affected by different states such as emotion, attention, motivation and perception resulting in impaired memory formation. Learning capabilities in simple organisms such as snails has always been a challenge when compared to complex organisms. This paper reports results from a set of pre- and post- learning cognitive based T-maze studies on snail, Achatina fulica. Preference, learning and short– and long- term memory retention based cognitive abilities of snails were studied using a modified T-maze. A significant difference in preference and memory gain of snails within the same group and species was observed under same conditions. Induced learning as change in arm preference was recognized by some snails, which retained this memory throughout the study. Some snails displayed learning traits during the learning period but reverted back to their original preference post learning. A rapid shift in preference post learning was verified as spontaneous alternation behaviour. Gradual reduction observed in runtime evaluated within a few hours post learning suggested a significant short term memory retention for these snails which was similar in case of long term memory, that was evaluated for a period of 20 days. Snails that showed restrictive learning patterns did not change their arm preference throughout the study and their behaviour was more resolute but eventually goal oriented. The results of this study demonstrates significant learning capability in this species with the ability to retain short and long term memory, confirming cognitive capabilities of a simple brain.
