Abstract
In the present study the capacity of Macrobrachium rosenbergii (de man) to respond to a food reinforced visual stimulus was tested. Four female Macrobrachia showed a significant reduction in approach latency, over 12 successive days with four trials each, to a stimulus consisting of a disc with horizontal stripes placed to the outside wall of the aquarium. No reinforcement of this newly acquired response led to extinction of the response after three days with four trials each day.
