Phonological-Lexical Processing and Word Learning in Preschool Children Differing in Phonological AwarenessLanguage skills influencing the emergence of phonological awareness are not well understood. Two theories present opposing views on the area of breakdown if phonological awareness is delayed. One focuses on the influence of phonological representations/processing (individual sounds), whereas another posits a link between lexical representations/processing (whole words) and phonological awareness acquisition. This study investigated both claims using a word-learning paradigm to observe phonological and lexical processing of the same (non)words before, during, and after they enter the lexicon. Results indicate that children with low phonological awareness evidence phonological processing deficits that, in turn, influence their subsequent word learning and lexical processing. Dr. Hogan is an Assistant Professor in the Department of Speech, Language, and Hearing Sciences at the University of Arizona, Tucson. Supported by the NIH Learnability Project and the American Speech-Language-Hearing Association Advancing Academic Research Careers Program Post-Laryngectomy Voice RestorationDr. Blom is an innovative and highly esteemed researcher and clinician who has made outstanding contributions to the fields of speech-language pathology and otolaryngology. Dr. Blom is the co-inventor of the Blom-Singer voice prosthesis, a device that has enabled thousands of people who undergone total laryngectomy to regain functional speech. As a speech-language pathologist, Dr. Blom has dedicated his professional life to the development of voice prostheses and to techniques of prosthesis insertion. Please come hear Dr. Blom discuss clinical issues related to the restoration of voice function following total laryngectomy. Spectral Weighting Strategies for Sentences Using a Correlational MethodSpeech recognition scores provide information on how well listeners perceive speech, but do not provide information about ‘how’ listeners perform the recognition task. For example, two listeners with the same hearing loss and same speech recognition score can use very different strategies to perform the task [Doherty and Lutfi, J. Acoust. Soc. Am. 105, 1831-1840 (1999)]. The correlational method [Lutfi, J. Acoust. Soc. Am. 97, 1333- 1334 (1995)] is one way to quantify how listeners use or weight spectral information in speech. The relative weight a listener places on specific frequency bands of a speech signal is referred to as a listener’s spectral weighting strategy. Spectral weighting strategies for sentences for listeners with normal hearing and listeners with hearing loss will be presented. In addition, data on the effects of presentation level on listeners’ spectral weighting strategies for sentences will be reported.
