“…According to this 1-dB criterion, for the stimuli used here ͑including the pink noise background͒, harmonics of the 200-Hz nominal-F0 complex were resolved up the seventh; the eighth and higher harmonics were unresolved. This is broadly consistent with the conclusions of several psychoacoustic studies in which direct measures of the ability to hear out harmonics were obtained ͑Plomp, 1964; Moore and Ohgushi, 1993;Moore et al, 2006͒, and one harmonic below that at which Bernstein and Oxenham ͑2006͒ estimated that the transition region between good and poor DLF0s occurred for F0s of around 175 Hz at moderate levels. 2 We also tested other values for the criteria.…”

This study measured difference limens for fundamental frequency ͑DLF0s͒ for a target harmonic complex in the presence of a simultaneous spectrally overlapping harmonic masker. The resolvability of the target harmonics was manipulated by bandpass filtering the stimuli into a low ͑800-2400 Hz͒ or high ͑1600-3200 Hz͒ spectral region, using different nominal F0s for the targets ͑100, 200, and 400 Hz͒, and different masker F0s ͑0, +9, or −9 semitones͒ relative to the target. Three different modes of masker presentation, relative to the target, were tested: ipsilateral, contralateral, and dichotic, with a higher masker level in the contralateral ear. Ipsilateral and dichotic maskers generally caused marked elevations in DLF0s compared to both the unmasked and contralateral masker conditions. Analyses based on excitation patterns revealed that ipsilaterally masked F0 difference limens were small ͑Ͻ2%͒ only when the excitation patterns evoked by the target-plus-masker mixture contained several salient ͑Ͼ1 dB͒ peaks at or close to target harmonic frequencies, even though these peaks were rarely produced by the target alone. The findings are discussed in terms of place-or place-time mechanisms of pitch perception.

“…He demonstrated that subjects were able to hear out only the first five to eight harmonics. More recent data confirm these results [5][6][7]. Pattern-recognition theories therefore predict that the lower resolved harmonics (up to the eighth) should be dominant in determining the pitch of complex tones.…”

When a complex tone contains many harmonics, its pitch is usually determined by harmonics in a restricted frequency region, called the ''dominant region,'' which for fundamental frequencies (F0s) ! 100 Hz corresponds to low, resolved harmonics. We estimated the dominant region for tones with low F0, by measuring thresholds, F0DLs, for detecting a change in F0 of a group of harmonics embedded within harmonics with fixed F0. The spectral position of the shifted group was systematically varied. Components were added in either cosine or random phase. For F0s of 35 and 50 Hz, the position of the dominant region depended strongly on the relative phases of the components. When the envelope had a low peak factor, with multiple peaks per period (random phase), the dominant region fell at low harmonic numbers (for F0 ¼ 50 Hz), or was not well defined (for F0 ¼ 35 Hz). When the envelope had a high peak factor, with one peak per period (cosine phase), the dominant region fell at high harmonic numbers, where harmonics were unresolved. Generally, performance was better for cosine than for random phase. The results indicate that harmonics in the dominant region are not always resolved.

“…Two complex tones comprising four components served as the standard and comparison tones. Two of the components within these tones were incremented by 7 dB to Decay uncovered in nonverbal short-term memory 11 create a change to the spectral profile, and the frequencies of the components were adapted from those used by Moore, Glasberg, Low, Cope, and Cope (2006). See Table 1 All individuals began the study with a number of training sessions, contrasting the standard and comparison tones over a silent 2 s interval until they could reliably perform the discrimination.…”

Decay theory posits that memory traces gradually fade away over the passage of time unless actively rehearsed. Much recent work exploring verbal short-term memory has challenged this theory, but there does appear to be evidence for trace decay in nonverbal auditory shortterm memory. Numerous discrimination studies have reported a performance decline as the interval separating two tones is increased, consistent with a decay process. However, most of the tone comparison research can be explained in other ways, without reference to decay, and these alternative accounts were tested in the present study. In Experiment 1 signals were employed towards the end of extended retention intervals to ensure that listeners were alert to the presence and frequency content of the memoranda. In Experiment 2 a mask stimulus was employed in an attempt to distinguish between a highly detailed sensory trace and a longerlasting short-term memory, and the distinctiveness of the stimuli was varied. Despite these precautions, slow-acting trace decay was observed. It therefore appears that the mere passage of time can lead to forgetting in some forms of short-term memory.
