Participants took part in two speech tests. In both tests, a model speaker produced vowel-consonant-vowels (VCVs) in which the initial vowel varied unpredictably in duration. In the simple response task, participants shadowed the initial vowel; when the model shifted to production of any of three CVs (/pa/, /ta/ or /ka/), participants produced a CV that(More)
BACKGROUND A common complaint of patients with (central) auditory processing disorder is difficulty understanding speech in noise. Because binaural hearing improves speech understanding in compromised listening situations, quantifying this ability in different levels of noise may yield a measure with high clinical utility. PURPOSE To examine binaural(More)
Although the theoretical importance of perspective taking has long been recognized, surprisingly little work has documented the cognitions associated with attempts to imagine another's point of view. To explore this issue and to determine whether perspective taking increases the likelihood of self-related thoughts, two experiments were carried out. In the(More)
The present review characterizes dual sensory impairment (DSI) as co-existing auditory and visual deficits in TBI that can be peripherally or centrally based. Current research investigating DSI in the military population, along with applicable research which focuses on unimodal deficits, is considered. Due to the heterogenous nature of TBI lesions, an(More)
The present review summarizes historic and recent research which has investigated the role of the corpus callosum in dichotic processing within the context of audiology. Examination of performance by certain clinical groups, including split brain patients, multiple sclerosis cases, and other types of neurological lesions is included. Maturational, age(More)
We tested the hypothesis that rapid shadowers imitate the articulatory gestures that structure acoustic speech signals-not just acoustic patterns in the signals themselves-overcoming highly practiced motor routines and phonological conditioning in the process. In a first experiment, acoustic evidence indicated that participants reproduced allophonic(More)
The Gaps-In-Noise (GIN) test is a new procedure used in the diagnosis of central auditory processing disorders. Performance on the GIN is recorded as approximate gap detection threshold and percent correct. In order to utilize the GIN test clinically, it is important to know how presentation level influences performance on the GIN. To this end, ten(More)
PURPOSE To provide a commentary on "Auditory Processing Disorder and Auditory/Language Interventions: An Evidence-Based Systematic Review" by Fey et al. (2011). METHOD Examination of the conclusions drawn by Fey et al. (2011) in the context of the American Academy of Audiology (2010a, 2010b) and American Speech-Language-Hearing Association (2005a, 2005b,(More)
BACKGROUND Use of a competition stimuli (e.g., video) in clinical settings is a widespread practice, yet the effects of these stimuli on evoked potentials are not well understood. PURPOSE The present investigation acquired the click evoked auditory N1-P2 in quiet and in two types of competition: during presentation of an unrelated visual stimulus or(More)
Psychophysical and P300 (P3) thresholds and suprathreshold measures were obtained in 16 normal-hearing subjects. Subjects followed a classic oddball paradigm using 1000 (frequent) and 2000 Hz (rare) tones as stimuli. The P3 was obtained for all 16 subjects at or 5 dB above their behavioral threshold. The P3 was obtained more often at behavioral threshold(More)
