Discrimination was examined using reference sequences consisting of five 50-ms tones separated by silent intervals; tone frequencies were either fixed at 4 kHz or varied within a 2\u20134-kHz range to produce spectrally complex patterns. The tonal IOIs within the reference sequences were either equal (200 or 600 ms) or varied individually with an average value of 200 or 600 ms to produce temporally complex patterns. The difference limen (DL) for increments of IOI was measured. Comparison sequences featured either equal increments in all tonal IOIs or increments in a single target IOI, with the sequential location of the target changing randomly across trials. Four groups of younger and older adults with and without sensorineural hearing loss participated. Results indicated that DLs for uniform changes of sequence rate were smaller than DLs for single target intervals, with the largest DLs observed for single targets embedded within temporally complex sequences. Older listeners performed more poorly than younger listeners in all conditions, but the largest age-related differences were observed for temporally complex stimulus conditions. No systematic effects of hearing loss were observed.<\/jats:p>","DOI":"10.1121\/1.1765192","type":"journal-article","created":{"date-parts":[[2004,8,2]],"date-time":"2004-08-02T22:35:34Z","timestamp":1091486134000},"page":"1126-1134","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":38,"title":["Age effects on discrimination of timing in auditory sequences"],"prefix":"10.1121","volume":"116","author":[{"given":"Peter J.","family":"Fitzgibbons","sequence":"first","affiliation":[{"name":"Department of Hearing, Speech, and Language Sciences, Gallaudet University, Washington, DC\u200920002"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sandra","family":"Gordon-Salant","sequence":"additional","affiliation":[{"name":"Department of Hearing and Speech Sciences, University of Maryland, College Park, Maryland\u200920742"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"231","published-online":{"date-parts":[[2004,8,2]]},"reference":[{"key":"2023071404524667200_abe72a","doi-asserted-by":"crossref","first-page":"1219","DOI":"10.1121\/1.1912963","article-title":"Duration discrimination of noise and tone bursts","volume":"51","year":"1972","journal-title":"J.
