Three experiments were conducted to examine the effects of trial-to-trial variations in speaking style, fundamental frequency, and speaking rate on identification of spoken words. In addition, the experiments investigated whether any effects of stimulus variability would be modulated by phonetic confusability (i.e., lexical difficulty). In Experiment 1,(More)
Recent studies have raised questions about the extent to which working memory (WM) is dissociable from secondary or long-term memory (LTM). Although many similarities may exist between immediate retrieval on WM span tasks and delayed retrieval on LTM tests, important differences exist as well. To illustrate this point, Craik and Tulving " s classic(More)
OBJECTIVE Our long-term objective is to develop an auditory training program that will enhance speech recognition in those situations where patients most want improvement. As a first step, the current investigation trained participants using either a single talker or multiple talkers to determine if auditory training leads to transfer-appropriate gains. (More)

BACKGROUND The human endometrium efficiently repairs each month after menstruation. The mechanisms involved in this repair process remain undefined. Aberrations in endometrial repair may lead to the common disorder of heavy menstrual bleeding. We hypothesized that connective tissue growth factor (CTGF) is increased at the time of endometrial repair(More)
BACKGROUND Patients seeking treatment for hearing-related communication difficulties are often disappointed with the eventual outcomes, even after they receive a hearing aid or a cochlear implant. One approach that audiologists have used to improve communication outcomes is to provide auditory training (AT), but compliance rates for completing AT programs(More)
PURPOSE Individuals with hearing loss engage in auditory training to improve their speech recognition. They typically practice listening to utterances spoken by unfamiliar talkers but never to utterances spoken by their most frequent communication partner (FCP)-speech they most likely desire to recognize-under the assumption that familiarity with the FCP's(More)
PURPOSE This investigation focused on generalization of outcomes for auditory training by examining the effects of task and/or talker overlap between training and at test. METHOD Adults with hearing loss completed 12 hr of meaning-oriented auditory training and were placed in a group that trained on either multiple talkers or a single talker. A control(More)
There has been considerable interest in measuring the perceptual effort required to understand speech, as well as to identify factors that might reduce such effort. In the current study, we investigated whether, in addition to improving speech intelligibility, auditory training also could reduce perceptual or listening effort. Perceptual effort was assessed(More)
Course Description This course examines theoretical and instructional implications of research on grammar and vocabulary acquisition. Topics include form-meaning connections during language learning; the roles of input and input processing; explicit and implicit grammar instruction; pertinent factors in vocabulary acquisition, such as learning context and(More)
