“…Stimulus features, such as spectral power distributions (that translate into colour perception) or sound pressure level (that contributes to loudness perception) have been discovered and are well defined, yet it would be ignorant to assume that we already have a comprehensive understanding of all stimulus features that are relevant to human perception. For example, research has only recently established the perceptual relevance of quasi-stationary sinusoidal components in acoustic object identification [36].…”

There is an uncountable number of different ways of characterizing almost any given realworld stimulus. This necessitates finding stimulus features that are perceptually relevant -that is, they have distinct and independent effects on the perception and cognition of the stimulus. Here, we provide a theoretical framework for empirically testing the perceptual relevance of stimulus features through their association with recognition, memory bias, and aesthetic evaluation. We deploy this framework in the auditory domain to explore the perceptual relevance of three recently developed mathematical characterizations of periodic temporal patterns: balance, evenness, and interonset interval entropy. By modelling recognition responses and liking ratings from 177 participants listening to a total of 1,252 different musical rhythms, we obtain very strong evidence that all three features have distinct effects on the memory for, and the liking of, musical rhythms. Interonset interval entropy is a measure of the unpredictability of a rhythm derived from the distribution of its durations. Balance and evenness are both obtained from the discrete Fourier transform (DFT) of periodic patterns represented as points on the unit circle, and we introduce a teleological explanation for their perceptual relevance: the DFT coefficients representing balance and evenness are relatively robust to small random temporal perturbations and hence are coherent in noisy environments. This theory suggests further research to explore the meaning and relevance of robust coefficients such as these to the perception of patterns that are periodic in time and, possibly, space.

“…It has yet remained unclear whether this onset advantage is due to enhanced perceptual encoding or the richness of acoustical information during onsets. Here this issue was approached by modeling a recent study on instrument identification from tone excerpts [Siedenburg 2019, JASA, 145(2), 1078-1087. A simple Hidden Markov Model classifier with separable Gabor filterbank features simulated human performance and replicated the onset advantage observed previously for human listeners.…”

“…Therefore, transients should not be confused with the onset as a whole: all sounds have onsets but not necessarily pronounced transients (e.g., the smooth onset of a clarinet sound). Siedenburg (2019) then quantified the individual contribution of transient components to instrument identifi-cation. Stationary and transient components were extracted from the audio signal and instrument identification was tested for gated excerpts containing stationary plus transient components, or stationary components alone.…”

Sound onsets provide particularly valuable cues for musical instrument identification by human listeners. It has remained unclear whether this onset advantage is due to enhanced perceptual encoding or the richness of acoustical information during onsets. Here this issue was approached by modeling a recent study on instrument identification from tone excerpts [Siedenburg. (2019). J. Acoust. Soc. Am. 145(2), 1078–1087]. A simple Hidden Markov Model classifier with separable Gabor filterbank features simulated human performance and replicated the onset advantage observed previously for human listeners. These results provide evidence that the onset advantage may be driven by the distinct acoustic qualities of onsets.
