Listening Effort: Separating The Subjective From The Objective, Joseph E. Rovetti
Listening Effort: Separating The Subjective From The Objective, Joseph E. Rovetti
Electronic Thesis and Dissertation Repository
Challenges such as background noise may increase “listening effort.” This construct has been operationalized as the recruitment of cognitive resources during listening (objective effort) or as the self-reported feeling of effort (subjective effort). In the current study, I compared these two dimensions of listening effort directly. Normal-hearing adults listened to highly intelligible passages across several signal-to-noise ratios (SNRs), with reaction time on a secondary task (objective effort) and effort ratings (subjective effort) measured in separate blocks. As the SNR became less favourable, subjective effort appeared to increase continuously, while objective effort only began to increase at a much less favourable …
The Relationship Between Schizotypal Traits And The Perceptual Processes Of Multisensory Integration, Temporal Processing, And Speech Perception, Anne-Marie Muller
The Relationship Between Schizotypal Traits And The Perceptual Processes Of Multisensory Integration, Temporal Processing, And Speech Perception, Anne-Marie Muller
Electronic Thesis and Dissertation Repository
Multisensory integration, the binding of sensory information from different sensory modalities, may contribute to perceptual symptomatology in schizophrenia, including hallucilllnations and aberrant speech perception. Differences in multisensory integration and temporal processing, an important component of multisensory integration, are consistently found in schizophrenia. Evidence is emerging that these differences extend across the schizophrenia spectrum, including individuals in the general population with higher schizotypal traits. In two studies, the relationship between schizotypal traits and perceptual functioning is investigated. We hypothesized associations between higher schizotypal traits and decreased multisensory integration, increased auditory speech distractibility, and less precise temporal processing. In Study 1, higher …
Characterizing The Familiar-Voice Benefit To Intelligibility, Beatriz Ysabel Domingo
Characterizing The Familiar-Voice Benefit To Intelligibility, Beatriz Ysabel Domingo
Electronic Thesis and Dissertation Repository
Everyday listening often occurs in the presence of background noise. Listeners with normal hearing can often successfully segregate competing sounds from the signal of interest. To do this, listeners exploit a variety of cues to facilitate the separation of simultaneous sounds into separate sources, and group sequential sounds into intelligible speech streams. One of the cues that has been shown to be an effective facilitator of speech intelligibility is familiarity with a talker’s voice. A recent study by Johnsrude et al. (2013) measured speech intelligibility of a naturally familiar voice (i.e., that of a long-term spouse) and showed a …
