In Introduction Sect, we mentioned that, in the auditory domain, flexibility of cue weighting has been studied mainly in the context of speech perception and phonetic categories. One exception is the study of Holt and Lotto (2006). They investigated the effect of short-term experience on relative cue weighting in relation to the formation of non-speech categories. They trained listeners to categorize sounds as belonging to one or the other of two previously unknown categories (buttons). The sounds were frequency-modulated sinusoids that differed in center frequency (CF) and modulation frequency (MF). One category contained tones with CFs that were, on average, lower than the CFs for the other category and with MFs that were, on average, higher than that for the other category. The tones were equally spaced in terms of just-noticeable-differences in both the CF and the MF dimensions. Listeners heard one tone at a time and learned category labels through visual feedback (a light). After training (less than 2 h), listeners had to categorize novel stimuli from the same two-dimensional (CF, MF) space (without feedback). Listeners gave more weight to the CF dimension than to the MF dimension when both dimensions were equally informative with regard to category membership. Decreasing the difference between the means of the two CF ranges, leading to more overlap of the two categories on the CF dimension, but keeping other statistics characterizing the distributions constant, did not change the relative weighting of the CF and MF dimensions by the listeners. However, when the variability of the CF was increased and that of the MF decreased, listeners gave more weight to the MF than the CF dimension. Therefore, even when cues were equally informative and discriminable, they were not weighted equally; listeners had a clear “bias” towards the CF cue. However, a change in weighting strategy could be produced by changes in the distribution of the input parameters. It should be noted that the combination of higher CFs with lower MFs and lower CFs with higher MFs might be considered as somewhat unnatural, as it would rarely be encountered.
