“…For example, several related metrics are used to define stimulus strength (Grantham and Yost, 1982;Green, 1993). The description and derivation of these metrics have been thoroughly dealt with by Hartmann (1995Hartmann ( , 1998; we will briefly discuss two classes that relate to intensity discrimination in insects.…”

Psychophysics has much to offer the study of insect hearing. Not only is there a rich set of experimental methods to apply, there is a large body of experimental work on vertebrate hearing that can suggest topics for investigation and provide material for cross-species comparisons. We present an overview of the methods of psychophysics, followed by specific examples of their use in insects. Topics covered include intensity discrimination, frequency analysis and discrimination, temporal integration and acuity, and localization. We conclude by pointing out additional areas of research suggested by the reviewed work and areas in which a psychophysical approach would be useful.

“…where the exponent, p, is 0.3 (Hellman and Hellman, 1990;Green, 1993;Plack and Carlyon, 1995) and the constant k is 1/15.849 (for a sone scale (Hartmann, 1997)). For sensation levels lower than 30 dB SL, no consensus exists on the form of the loudness function, but generally it is steeper than at moderate level (Buus et al, 1998).…”

“…When the increments are as small as those commonly used in level discrimination procedures, it is possible to choose between ⌬I / I, ⌬A / A, or ⌬L with immunity because of the proportional relationship these measures have to one another. The correct measure cannot be determined from data collected using this typical range of levels (Green, 1993;Moore et al, 1999).…”

Psychometric functions collected from difference discrimination tasks typically have slopes near 1, whereas those from increment detection tasks have slopes near 2. Experiments exploring the effect of stimulus configuration on the psychometric function were undertaken. Some stimuli were configured to conform to difference discrimination and increment detection tasks, while other “hybrid” stimulus configurations had physical properties associated with both tasks. The results suggest that these hybrid configurations may have psychophysical properties that fall in between those found for difference discrimination and increment detection tasks.
