 note = {The present study examined the effects of arm properties involving arm width and obstruc- tive objects on radial maze performance in gold sh (Carassius auratus). Three groups of gold sh were trained to perform a typical win-shift free choice task in one of the three conditions of an eight-arm radial water maze. Arm width of the maze was 5 cm for Group 5 cm (n=3) and 3 cm for Group 3 cm (n=3). For Group curtain (n=4), arm width was 5 cm but a curtain made of 0.5 mm thick silicon was set in each arm. To enhance arm identity, some arms of the mazes were differentially colored and different objects were placed on the oor of the arms. Group 3 cm made signi cantly greater correct responses than Group 5 cm and Group curtain within the initial eight choices of a trial. Performance of Group 5 cm and Group curtain was almost chance level during the ve training blocks of eight trials. Group 5 cm showed signi cantly greater re-entry errors to complete trials than Group 3 cm. Arm width proved to affect the gold sh ’s performance, but the introduction of curtain did not. Several causes for the results were discussed.},
