Sequences of clicks comprising a dominant regular interval were investigated psychophysically. The first sequence pattern consisted of one regular interclick interval followed by two random intervals. The second sequence pattern consisted of one regular interval with a randomly interspersed click, followed by a single random interval. These stimuli had a single normalized autocorrelation peak of identical height at the regular interval. They were also equated in average rate. In a pitch…

Physiological correlates of the perceptual pitch shift for sounds with similar waveform autocorrelation

A perceptual experiment shows that random click trains with a uniform interclick distribution can be reliably pitch-matched to pseudo-periodic click trains and similar cues are found in either first-order or all-order interspike interval statistics.

Pitch strength of regular-interval click trains with different length "runs" of regular intervals.

The results indicate that fine-structure regularity plays a more important role in pitch perception than randomness, and that the long-term autocorrelation function or spectra of these click trains are not good predictors of pitch strength.

A cascade autocorrelation model of pitch perception.

This study addresses the issue of whether in the light of these challenges the predictive power of autocorrelation can be preserved by changes to the peripheral model and the computational algorithm.

Discrimination of first- and second-order regular intervals from random intervals as a function of high-pass filter cutoff frequency.

While RIS click trains with first-order intervals are more easily discriminated from random-interval stimuli than second-order interval RIS click train, discrimination based on second- order intervals is possible except when the stimuli are high-pass filtered above 8 kHz, i.e., above the spectral region of phase locking.

The case of the missing delay lines: synthetic delays obtained by cross-channel phase interaction.

A mechanism by which delays may be synthesized from cross-channel phase interaction is proposed by which Phases of adjacent cochlear filter channels are shifted by an amount proportional to frequency and then combined as a weighted sum to approximate a delay.

Understanding Pitch Perception as a Hierarchical Process with Top-Down Modulation

This study presents an idealized neurocomputational model, which provides a unified account of the multiple time scales observed in pitch perception and suggests a key role for efferent connections from central to sub-cortical areas in controlling the temporal dynamics of pitch processing.

Behavioral and physiological correlates of temporal pitch perception in electric and acoustic hearing.

The results are compared to the predictions of a simple model incorporating auditory-nerve (AN) refractoriness, and where pitch is estimated from first-order intervals in the AN response, resulting in a modulated pattern that was independent of overall level.

An autocorrelation model with place dependence to account for the effect of harmonic number on fundamental frequency discrimination.

A modified unitary pitch model was able to account for the dependence of f0 DLs on harmonic number, although this correct behavior was not based on peripheral harmonic resolvability.

Pitch perception and harmonic resolvability in normal-hearing and hearing-impaired listeners

Listeners with sensorineural hearing loss are often impaired in their ability to perceive the pitch associated with the fundamental frequency (FO) of complex harmonic sounds. Four studies

Neural correlates of the pitch of complex tones. I. Pitch and pitch salience.

The temporal discharge patterns of auditory nerve fibers in Dial-anesthetized cats were studied in response to periodic complex acoustic waveforms that evoke pitches at their fundamental frequencies, suggesting that existence of a central processor capable of analyzing these interval patterns could provide a unified explanation for many different aspects of pitch perception.

Psychophysical evidence against the autocorrelation theory of auditory temporal processing.

It is suggested that the extraction of temporal information from a group of closely spaced spectral components makes no use of time intervals between nonconsecutive peaks of the amplitude envelope, which does not tally with the current autocorrelation models of temporal processing.

The results suggest that the strength of the pitch of IRN stimuli is based on temporal processing as might be revealed by autocorrelation.

Pitch identification and discrimination for complex tones with many harmonics

Four experiments are reported that deal with pitch perception of harmonic complex tones containing up to 11 successive harmonics. In particular, the question is raised whether the pitch percept of

A theory was formulated for the central formation of the pitch of complex tones, i.e., periodicity pitch. This theory is a logical deduction from statistical estimation theory of the optimal estimate

A unitary model of pitch perception.

It is shown that the model can simulate new experimental results that show how the quality of the pitch percept is influenced by the resolvability of the harmonic components of the stimulus complex and it is not necessary to postulate two separate mechanisms to explain different pitch percepts associated with resolved and unresolved harmonics.

The lower limit of melodic pitch.

A computational auditory model that extracts pitch information with autocorrelation can reproduce all of the observed effects, provided the contribution of longer time intervals is progressively reduced by a linear weighting function that limits the mechanism to time intervals of less than about 33 ms.

An adaptive procedure for subjective judgments

An adaptive psychophysical procedure is one in which the stimuli presented on a given trial are determined by the observer's responses on previous trials. In recent years, considerable progress has
