The cross-modal matching of brightness to loudness by children

According to Stevens' explanation of cross-modal matching, the recruitment-like effects of masking seen in intramodal loudness judgements should be reflected in a brightness-to-loudness matching task. In an experiment with child observers, this failed to occur. The results are explicable in terms of category mediation of the cross-modal, but not the intramodal, task. In support of this account, it is shown that cross-modal judgements are unaffected by explicit category mediation. However, intramodal judgements, explicitly mediated in the same way, produce a pattern of results similar to those obtained in the cross-modal task. The experiments suggest that cross-modal matching does not provide a useful test of loudness recruitment in the bilaterally hearing impaired.
