Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Findings with the low-level sound-induced flash illusion are inconsistent: half of four studies found reduced integration in autistic individuals and half found no between-group differences. → Wallace 2020
Evidence¶
Wallace 2020¶
Wallace, M. T., Woynaroski, T. G., & Stevenson, R. A. (2020). Multisensory Integration as a Window into Orderly and Disrupted Cognition and Communication. Annual Review of Psychology. https://doi.org/10.1146/annurev-psych-010419-051112
q2 · i? · review · r3
The review reports mixed findings for the sound-induced flash illusion in autism: the two studies testing children found significant reductions while the two testing adults failed to find differences, suggesting possible developmental trajectory differences.
"Across four studies utilizing this low-level illusion to date, half have found significantly reduced multisensory integration for autistic individuals relative to controls (Foss-Feig et al.2010,Stevenson et al.2014b),and half have failed to detect between-group differences (Keane et al.2010,van der Smagt et al.2007)"
Discussion¶
Learner Variables¶
- Learning Disabilities and Developmental Differences — predictor: learners who differ on it differ in outcomes
