A model was proposed as an alternative to current models for categorical perception, which refers to the apparent responding to stimuli only in absolute terms. The model proposed that a single (common) factor causes both a peak in the discrimination function and a categorical dichotomy and thus the correlation between the two. (Editor/RK)

Research by Posner and Mitchell (1967) was used to investigate levels of noise processing in testing subjects' ability to "gate out" the processing of irrelevant and unwanted material. Three experiments are reported in which subjects had to judge whether two letters were the "same" or "different". Noise elements were included to test attention…

Three experiments investigated the relationship in speech perception between the mechanisms that determine the source of speech sounds and those that analyze their actual acoustic contents and extract from them the acoustic cues to a sound's phonetic description. (Author/RK)

Three experiments were performed using a recognition probe procedure to test the subject's recognition of the order of two items from a dichotically presented list. (Editor)

A phonetic confusion model and some procedural artifacts were eliminated as sources for individual differences in fusion rate. Results of these two experiments were consistent with the hypothesis that individual differences in fusion rate are due to differences in perceptual dependence on linguistic rules. (Editor/RK)

In 1974 Wood proposed a hybrid serial-parallel model to account for the within-stimulus interactions between the acoustic cue of "pitch" and the phonetic cue of "place". These experiments found Wood's research independent of his subjects' experience, the order of cue presentation, and whether the cues are presented simultaneously or sequentially.…

Considers listener expectancies based on timing redundancy in continuous speech and the interaction between the effects of segmental and suprasegmental cues during ongoing perception. (Editor/RK)
