Abstract : This supplemental grant supported a graduate student, Ward Drennan. During the grant period, Mr Drennan collaborated on two major research projects. The first project involved frequency discrimination of a single central tone in a sequential sequence of 9 tones under minimal uncertainty conditions. The second project involved intensity discrimination of a single central tone in a complex of 11 tones presented simultaneously or profile analysis. The primary results of the first project were presented at the 125th meeting of the Acoustical Society of America (ASA) (Watson, et al. 1993a, 1993b). The results of the second project were presented at the 129th, 131st and 132nd meetings of ASA (Watson and Drennan, 1995; Drennan and Watson, 1996a, 1996b).
