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.
q3 i2 After the stimulus mean frequency shifted, the intercept of the ASD group's accuracy curves remained closer to the previous context's mean in the first TOE block, indicating slower prior updating. → Sapey-Triomphe 2023

Exp. III compared the accuracy-curve intercepts to the previous (30 Hz) versus current (26 Hz) context means. The intercept was "higher (i.e., closer to the mean stimulus frequency of the context-setting blocks)" in ASD in the first TOE block (d = 0.71), but not in the second, indicating both groups adjusted flexibly yet ASD more slowly.
"This intercept was higher (i.e., closer to the mean stimulus frequency of the context-setting blocks) in the ASD group than in the NT group in the first TOE block ( t(35) = 2.1, p = 0.045, d = 0.71, BF = 1.68)"
Discussion¶
Learner Variables¶
- Learning Disabilities and Developmental Differences — predictor: learners who differ on it differ in outcomes
Related Claims¶
- Neurotypical and autistic adults show similar average tactile detection thresholds and discrimination accuracy — related
- Both neurotypical and autistic adults implicitly learn a prior that biases tactile perception (time-order effect) — related
- Computational modeling shows a lower sensory/prior precision ratio in autistic adults in Exp. II and an opposite response bias across groups — related
- Massed exposure to a single frequency produces lasting suppression of detection at distant frequencies — related
- Sensory adaptation occurs in neurotypical but not autistic adults in tactile detection — related
- Prior influence on perception is stronger in autistic than neurotypical adults in a stable context, but not after a frequency-range change — related
