“…It has also been suggested that the body of the caudate may be involved in classification learning independently of the role of the head of the caudate in feedback processing (Seger & Cincotta, 2005). In visual classification research, the role of the tail and sometimes body of the caudate is often emphasized (e.g., Seger & Cincotta, 2005;Ashby & Ell, 2002;Maddox, Molis, & Diehl, 2002). Similarly, Ashby and Ell (2002) posit that auditory stimulus-category associations should activate the body of the caudate.…”

“…This approach is similar to evaluations of model performance described by Maddox et al ͑2002͒ andNearey andKiefte ͑2003͒ and some of the data modeled here also served as the basis for a comparison of visual and auditory models of categorization by Maddox and colleagues ͑2002͒. Through logistic regression analysis, any number of categorical or continuous independent variables can be used to model the categorical outcome of a dependent variable ͑Hosmer and Lemeshow, 1989͒.…”

“…In previous investigations, Nearey and Kiefte ͑2003͒ found that adding nonlinear ͑quadratic͒ formant terms improved the fit of the multinomial logistic regression analysis of a large F1-F2-F3 vowel space relative to the linear terms alone. Maddox et al ͑2002͒ investigated decision processes in the categorization of vowels using both linear and nonlinear formant models and also found improved fits when nonlinear boundaries were allowed. Hillenbrand and Gayvert ͑1993͒ evaluated a nonlinear classification method for spoken vowels, and compared their results with earlier studies that used linear analyses.…”

“…The concept of multiple learning systems mediating categorization has been recently applied in the auditory domain, in studying vowel processing (Maddox, Molis, & Diehl, 2002), as well as learning tonal categories in adulthood . These studies have shown that successful learning of speech categories activates the neural circuitry involved in implicit, procedural-learning .…”
