The leading tonal marker was always a 20-ms, 250-Hz complex tone with energy at 250, 500, 750, and 1000\u2009Hz. The lagging marker, also tonal, could differ from the leading marker with respect to fundamental frequency (f0), the presence versus absence of energy at f0, and the degree to which it overlapped spectrally with the leading marker. All stimuli were presented with steeper (1\u2009ms) and less steep (4\u2009ms) envelope rise and fall times. F0 differences, decreases in the degree of spectral overlap between the markers, and shallower envelope shape all contributed to increases in gap-detection thresholds. Age differences for gap detection of complex sounds were generally small and constant when gap-detection thresholds were measured on a log scale. When comparing the results for complex sounds to thresholds obtained for pure-tones in a previous study by Heinrich and Schneider [(2006). J. Acoust. Soc. Am. 119, 2316\u20132326], thresholds increased in an orderly fashion from markers with identical (within-channel) pure tones to different (between-channel) pure tones to complex sounds. This pattern of results was true for listeners of both ages although younger listeners had smaller thresholds overall.<\/jats:p>","DOI":"10.1121\/1.4894788","type":"journal-article","created":{"date-parts":[[2014,10,8]],"date-time":"2014-10-08T00:31:21Z","timestamp":1412728281000},"page":"1797-1807","update-policy":"http:\/\/dx.doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":9,"title":["The role of stimulus complexity, spectral overlap, and pitch for gap-detection thresholds in young and old listeners"],"prefix":"10.1121","volume":"136","author":[{"given":"A.","family":"Heinrich","sequence":"first","affiliation":[{"name":"University of Toronto Mississauga Human Communication Laboratory, Department of Psychology, , 3359 Mississauga Road North, Mississauga, Ontario L5L 1C6, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"de la Rosa","sequence":"additional","affiliation":[{"name":"University of Toronto Mississauga Human Communication Laboratory, Department of Psychology, , 3359 Mississauga Road North, Mississauga, Ontario L5L 1C6, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B.
