Musicianship confers enhancements to hearing at nearly all levels of the auditory system from periphery to percept. Musicians' superior psychophysical abilities are particularly evident in spectral discrimination and noise-degraded listening tasks, achieving higher perceptual sensitivity than their nonmusician peers. Greater spectral acuity implies that musicianship may increase auditory filter selectivity. ...

The present work investigated consumers' hedonic response to flavor stimuli in light of Berlyne's (1967) collative-motivational model of aesthetic preferences. According to this paradigm, sensory preferences are a function of a stimulus' arousal potential, which is determined by its collative properties. The relationship between overall arousal potential and hedonic response ...

By attenuating neural and perceptual responses to sustained stimulation, adaptation enhances the detection of new, transient stimuli. Disadaptation serves a similarly important role as a temporal filter for chemoreceptor cells, producing rapid recovery of sensitivity upon termination of the adapting odorant. Previous research from our laboratory indicated that a rapid ...
