Subclaims¶

q2 i? Individuals with reading impairments show reduced McGurk perception, poorer audiovisual temporal acuity, less multisensory reaction-time gain, and reduced visual-cue benefit on speech-in-noise tasks. → Wallace 2020 q2 i? Sensitivity to audiovisual synchrony accounts for unique variance in reading accuracy in adults with dyslexia after controlling for working memory, processing speed, associative learning, and cognitive flexibility. → Wallace 2020 (2)

The review reports, citing multiple studies, that individuals with reading impairments show reduced McGurk influence "at least under some listening conditions", poorer audiovisual temporal acuity, and less multisensory reaction-time gain relative to controls.

q2 · i? · review · r3

The review reports, citing Francisco et al., that audiovisual synchrony sensitivity accounted for unique variance in reading accuracy in adults with dyslexia even after controlling for working memory, processing speed, associative learning, and cognitive flexibility.

"Aspects of multisensory processing (specifically sensitivity to audiovisual synchrony) have further been observed to account for unique variance in reading accuracy in adults with dyslexia, even after controlling for several previously identi- fied predictors of reading ability (including working memory,processing speed,associative learn- ing, and cognitive flexibility) (Francisco et al. 2017)"

Discussion¶

Learner Variables¶

• Auditory Processing — predictor: learners who differ on it differ in outcomes
