  1. Cross-sectional study of differences in speech understanding between users and nonusers of estrogen replacement therapy.

    Experimental Aging Research 30(2):195 (2004) PMID 15204632

    The purpose of this study was to examine whether women who use estrogen replacement therapy (ERT) differ from women not using ERT on several measures of speech understanding. Participants (n = 38, 60 to 74 years) completed a battery of tests including pure-tone audiometry, the Dichotic Sentence Iden...
  2. [Analysis of acoustic and vocal processes in children with Gilles de la Tourette's disease using dichotic listening tests].

    Zhurnal nevropatologii i psikhiatrii imeni S.S.... 90(8):72 (1990) PMID 2175128

    A study was made of the specificity of interhemispheric interaction in realization of acoustic and vocal processes in children with Gilles de la Tourette's syndrome. 27 patients aged 8 to 12 years were selected for the studies. The research method used was dichotic listening. There were material dif...
  3. Null hypothesis disrespect in neuropsychology: dangers of alpha and beta errors.

    Neuropsychology, Development and Cognition. Sec... 10(2):255 (1988) PMID 3350924

    These results are also discussed in the broader context of the necessity for investigators in neuropsychology to differentiate between the statistical and clinical significance of research findings; and to develop a more positive attitude toward the design, execution, and publication of replication...
  4. Release from first-formant masking in presbyacusis.

    Audiology (Switzerland) 23(2):165 (1984) PMID 6721788

    Using synthetic vowels, the effects of first-formant masking on discrimination of the presence of a transition in the second formant were measured under conditions of first-formant attenuation and dichotic presentation. The subjects were 26 listeners between the ages of 61 and 91 with borderline to...
  5. Assessment and remediation of an auditory processing disorder associated with head trauma.

    Journal of the American Academy of Audiology 15(2):117 (2004) PMID 15112839

    This case study involves a 41-year-old female who had sustained a mild traumatic brain injury during a horseback riding accident. The patient was seen for medical and neuropsychological testing following this incident and was referred to a speech-language pathologist for rehabilitative services. At...
  6. [Specificity of hemispheric asymmetry in prosody perception in schizophrenia and in the norm].

    Fiziologiia cheloveka 30(4):32 (2004) PMID 15495521

  7. ERP indicators of disturbed attention in mild closed head injury: a frontal lobe syndrome?

    Psychophysiology 36(6):802 (1999) PMID 10554593

    The purpose of the study was to examine the hypothesis that distractibility is a fundamental characteristic of mild closed head injury (MHI). The claim that cognitive symptoms in MHI are due to a mild type of frontotemporal injury was also investigated. Cognitive event-related potentials (ERPs), acc...
  8. Speech enhancement based on physiological and psychoacoustical models of modulation perception and binaural interaction.

    Journal of the Acoustical Society of America 95(3):1593 (1994) PMID 8176062

    A novel approach for analyzing and filtering speech is described and evaluated which utilizes the "modulation spectrogram," i.e., the two-dimensional representation of modulation frequencies versus center frequency as a function of time. This approach is based on physiological findings of a tonotopi...
  9. Enhancing and unmasking the harmonics of a complex tone.

    Journal of the Acoustical Society of America 120(4):2142 (2006) PMID 17069312

    We provide the first experimental evidence for unmasking. Harmonics of 200 Hz, with harmonic numbers between about 5 and 16, are readily unmasked. Their pitches are usually matched by sine tones with frequencies that are not exactly those of the unmasked harmonics but are shifted in a direction away...
  10. Asymmetry of masking between complex tones and noise: partial loudness.

    Journal of the Acoustical Society of America 114(1):349 (2003) PMID 12880046

    This experiment examined the partial masking of periodic complex tones by a background of noise, and vice versa. The tones had a fundamental frequency (F0) of 62.5 or 250 Hz, and components were added in either cosine phase (CPH) or random phase (RPH). The tones and the noise were bandpass filtered...
