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)

If the N1 wave (amplitude component between 80-130 msec) does not serve as an index of an initial stimulus set stage of selection, the N1 amplitudes should be differentiated between channels whether the selection is based on pitch, spatial position, intensity, or cues that lead to an efficient rejection of unwanted information. This study…

Two experiments investigated the effects of feedback on absolute judgments of loudness. (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)

A multiple regression analysis of sequential effects in magnitude estimation and absolute identification is presented as an alternative to the approach used by Lockhead and his students. The new analysis indicates that sequential effects do not extend over more than one trial. (Editor)

Names of cities were shock associated and then embedded in material presented to the nonattended channel in a dichotic listening and shadowing situation. A test for conditioning followed the dichotic listening task. Comparisons are made with other studies of galvanic skin responses to unattended words. (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)
