Abstract

This study examined a conjugate approach for evaluating auditory stimulus preference for 81 participants using force as a continuous response dimension. First, the researchers used a verbal preference assessment to evaluate each participant's preference for listening to five genres of music. This process identified high-preference and low-preference music for each participant. Thereafter, the researchers exposed each participant to the five music genres in a randomized order while using a hand dynamometer to measure their response force to increase the auditory clarity of the music. The results indicate (a) 63% of the participants' high-preference music genres corresponded to the genre for which they exerted the highest mean force and (b) most participants' low-preference music genres corresponded to the genre for which they exerted the lowest mean force. These findings are consistent with those from Davis et al. (2021) and further support using conjugate preparations for measuring the relative value of some stimulus events.
