Cognitive resources in audiovisual speech perception
… senses with correlated information, and audiovisual speech perception is a familiar instance of multisensory integration. Several approaches will be used to further examine the role of cognitive factors on audiovisual speech perception. The main focuses of this thesis will be to examine …

Sources and Correlates of Performance Enhancement in Audiovisual Speech Perception
In a noisy environment, speech intelligibility is greatly enhanced by seeing the speaker’s face. This enhancement results from the integration of auditory and visual signals, but the underlying mechanisms remain largely unknown. This thesis describes the results from four studies investigating the …

Neural Correlates of Audiovisual Speech Perception In Aphasia and Healthy Aging
<p>Understanding speech in face-to-face conversation utilizes the integration of multiple pieces of information, most importantly the auditory vocal sounds and visual lip movements. Prior studies of the neural underpinnings of audiovisual integration in the brain have provided converging evidence …

The Effect of Age-related Declines in Inhibitory Control on Audiovisual Speech Intelligibility
Audiovisual: AV) speech perception is perception in which both auditory and visual information is available in order to understand a talker, compared to an auditory signal alone, during face-to-face communication. This form of communication yields significantly higher word recognition performance …

Investigating The Neural Basis of Audiovisual Speech Perception With Intracranial Recordings In Humans
<p>Speech is inherently multisensory, containing auditory information from the voice and visual information from the mouth movements of the talker. Hearing the voice is usually sufficient to understand speech, however in noisy environments or when audition is impaired due to aging or disabilities, …

Audiovisual perception of Mandarin lexical tones.
… and lip movements plays an important role in speech perception of spoken languages. Visual information facilitates speech perception in audiovisual congruent condition and even alters speech perception in audiovisual incongruent condition. Audiovisual speech perception has been greatly …

The Neural Substrates of Multisensory Speech Perception
<p>Comprehending speech is one of the most important human behaviors, but we are only beginning to understand how the brain accomplishes this difficult task. One key to speech perception seems to be that the brain integrates the independent sources of information available in the auditory and …

Deficits in inhibitory function mediate age-related multisensory and postural function decline
… information and difficulty in comprehending speech in a crowded, noisy room. Indeed, impaired multisensory processing has been consistently reported in older adults. Specifically, reduced sensitivity to temporal delays between bimodal cues, can affect the reliability of perceptual …
