Abstract
In this paper, both eye tracking data & connectionist simulations are used to investigate the temporal properties of phoneme categorization. It is hypothesized that there are three possibilities for the time course of categorical voicing identification: linear, linear-to-sigmoid, & expanding sigmoid. These possibilities are tested in an eye tracking experiment in which subjects (N = 16) are asked to use a mouse to click on either the label ba or pa on a computer screen in response to auditory stimuli. Results show that for ambiguous tokens, subjects look equally at either label before making a decision. The more accurate the stimuli are, the more likely subjects are to look at the correct label. This is claimed to be evidence in favor of the expanding sigmoid pattern. A connectionist simulation demonstrates that only a network combining competitive Hebbian learning & a "settling" algorithm can accurately model the categorical perception data. 10 Figures, 19 References.
