Can philosophical theories of perception defer to perceptual science when fixing their ontological commitments regarding the objects of perception? Or in other words, can perceptual science inform us about the nature of perception? Many contemporary mainstream philosophers of perception answer affirmatively. However, in this essay I provide two arguments against this idea. On the one hand, I will argue that perceptual science is not committed to certain assumptions, relevant for determining perceptual ontology, which however are generally relied upon by philosophers (...) when interpreting such science. On the other hand, I will show how perceptual science often relies on another assumption, which I call the ‘Measuring instrument conception’ of sensory systems, which philosophers of perception should clearly reject. Given these two symmetric lines of argument, I will finally suggest that we ought to think differently about the relationship between perceptual science and the philosophy of perception. (shrink)

Listeners can attend to and track instruments or singing voices in complex musical mixtures, even though the acoustical energy of sounds from individual instruments may overlap in time and frequency. In popular music, lead vocals are often accompanied by sound mixtures from a variety of instruments, such as drums, bass, keyboards, and guitars. However, little is known about how the perceptual organization of such musical scenes is affected by selective attention, and which acoustic features play the most important role. To (...) investigate these questions, we explored the role of auditory attention in a realistic musical scenario. We conducted three online experiments in which participants detected single cued instruments or voices in multi-track musical mixtures. Stimuli consisted of 2-s multi-track excerpts of popular music. In one condition, the target cue preceded the mixture, allowing listeners to selectively attend to the target. In another condition, the target was presented after the mixture, requiring a more “global” mode of listening. Performance differences between these two conditions were interpreted as effects of selective attention. In Experiment 1, results showed that detection performance was generally dependent on the target’s instrument category, but listeners were more accurate when the target was presented prior to the mixture rather than the opposite. Lead vocals appeared to be nearly unaffected by this change in presentation order and achieved the highest accuracy compared with the other instruments, which suggested a particular salience of vocal signals in musical mixtures. In Experiment 2, filtering was used to avoid potential spectral masking of target sounds. Although detection accuracy increased for all instruments, a similar pattern of results was observed regarding the instrument-specific differences between presentation orders. In Experiment 3, adjusting the sound level differences between the targets reduced the effect of presentation order, but did not affect the differences between instruments. While both acoustic manipulations facilitated the detection of targets, vocal signals remained particularly salient, which suggest that the manipulated features did not contribute to vocal salience. These findings demonstrate that lead vocals serve as robust attractor points of auditory attention regardless of the manipulation of low-level acoustical cues. (shrink)

This thesis explores the concept of timbre through the lens of analytic philosophical aesthetics and philosophy of music. I argue that timbre should be thought of as providing the grounds for artistic and aesthetic values in music. To this end and firstly, I critique the physical sense of timbre in favour of two anti-realist senses of timbre. These two are the qualitative and the semantic senses which are developed from two of Siedenburg and McAdams’ four senses of timbre. I argue (...) that the qualitative sense of timbre is the experience of the unique qualities of sounds. The semantic sense is that which associates timbres to objects and concepts. Within the semantic sense, I argue for what I call a genealogical sense of timbre which relates timbres to sources and concepts through a history of built up associations. Secondly, these two senses are situated within the artform of music by demonstrating the functions they may fulfil there and how these ground artistic and aesthetic values. Regarding these values, I employ Robert Stecker’s definitions of artistic and aesthetic value. Finally, I summarise the two arguments for why we should think that timbre can provide grounds for aesthetic and artistic value in music. (shrink)
