A study explored the relationship between the second language (L2) production of the Spanish stop consonants /p/ and /b/. Subjects were native English-speaking students enrolled in an undergraduate Spanish phonetics course. Data were collected on their production of Spanish /p,b/ in sentence context, and on their perceptual boundary between the…

This study presents an empirical investigation of basic processes in the perception of speech sounds. The experimental methods applied have their roots in two different psycholinguistic research paradigms; i.e., "categorical perception" and "dichotic listening." In the categorical perception paradigm, listeners' categorization…

A study employed computational and experimental methods to address a number of issues related to the representation and structural organization of spoken words in the mental lexicon. Using a computerized lexicon consisting of phonetic transcriptions of 20,000 words, "similarity neighborhoods" for each of the transcriptions were computed.…

Summarizing research activities from October 1978 to August 1979, this is the fifth annual report of research on speech processing conducted in the Department of Psychology at Indiana University. The report includes extended manuscripts, short reports, progress reports, and information on instrumentation developments and software support. The…

Using standard classical conditioning and concept-formation paradigms, research showed that all phones of a phoneme were considered "the same" by linguistically naive speakers. Results also supported the notion of the phoneme as a unit that functions in speech perception. (RL)

Twenty college students participated in an examination of the role of auditory feedback in the encoding of paralinguistic affect by adults. A dependent measure indicating the accuracy of paralinguistic communication of affect was obtained by comparing the level of affect that encoders intended to produce with ratings of vocal intonations from…
