title: Revisiting Psychoacoustic Methods for the Assessment of Fish Hearing.
abstract: Behavioral methods have been critical in the study of auditory perception and discrimination in fishes. In this chapter, we review some of the common methods used in fish psychoacoustics. We discuss associative methods, such as operant, avoidance, and classical conditioning, and their use in constructing audiograms, measuring frequency selectivity, and auditory stream segregation. We also discuss the measurement of innate behavioral responses, such as the acoustic startle response (ASR), prepulse inhibition (PPI), and phonotaxis, and their use in the assessment of fish hearing to determine auditory thresholds and in the testing of mechanisms for sound source localization. For each psychoacoustic method, we provide examples of their use and discuss the parameters and situations where such methods can be best utilized. In the case of the ASR, we show how this method can be used to construct and compare audiograms between two species of larval fishes, the three-spined stickleback (Gasterosteus aculeatus) and the zebrafish (Danio rerio). We also discuss considerations for experimental design with respect to stimulus presentation and threshold criteria and how these techniques can be used in future studies to investigate auditory perception in fishes.
