Predicting Individual Listener Confusions in the Classification of Complex. Steady-State Sounds.

Abstract

The classification model proposed by Howard, Ballas and Burgy (1978) estimates attentional capacity and how it is allocated to the relevant dimensions. It was hypothesized that capacity will vary as a function of individuals but that the allocation of capacity is a function of dimensional relevance. A classification experiment was conducted using amplitude-modulated noise with modulation frequency (Tempo) and waveform attack (Quality) as relevant dimensions. Subjects were required to classify sixteen sounds into eight categories emphasizing one of the dimensions for eight blocks (1536 trials) and then the other dimension for eight blocks. Capacity was estimated by the model and was equivalent for both classification tasks for individual subjects. Allocation of capacity reflected dimensional relevance. (Author)
