Distinctive Phonetic Features as Relevant and Irrelevant Stimulus Dimensions in Speech-Sound Discrimination Learning
Stuart I. Ritterman, Nancy C. Freeman · Journal of Speech and Hearing Research · 1974
Thirty-two college students were required to learn the relevant dimension in each of two randomized lists of auditorily presented stimuli. The stimuli consisted of seven pairs of CV nonsense syllables differing by two relevant dimension units and from zero to seven irrelevant dimension units. Stimulus dimensions were determined according to Saporta’s units of difference. No significant differences in performance as a function of number of the irrelevant dimensions nor characteristics of the relevant dimension were observed.
