| Abstract |
|
Evidence is presented that the semiaquatic turtle Trachemys scripta and the terrestial turtle Terrapene carolina major can detect the direction of a tone within their sensitive area of hearing. The stimulus was a 5% modulated 500-Hz tone generated in a Y maze with speakers at a 45° angle. The SPL at the discrimination area of the maze was 82 dB. Only one turtle of each species met the criteria of either ten consectuve correct responses or an overall 75% correct response level. However, all other animals responded above chance. Lastly, evidence is presented suggesting that the turtle can use its limited hearing in a problem solving situation.
