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 i3 Both groups exhibited a significant time-order effect in the TOE blocks of Experiments II and III, revealing implicit prior learning in ASD as in NT. → Sapey-Triomphe 2023

q3 · i3 · causal · r1
In Exp. II's TOE blocks, "Both groups exhibited a TOE" with ITOE strongly above zero in NT (30 ± 15) and ASD (47 ± 16), both p < 0.0001; a parallel result held in Exp. III, indicating both groups learned and used the stimulus-range prior.
"Both groups exhibited a TOE (Fig. 4a, b), with an ITOE significantly different from zero in NT (ITOE = 30 ± 15, t(16) = 8.5, p < 0.0001, d = 2.1, BF = 5.98 × 104) and ASD ( ITOE = 47 ± 16, t(15) = 12.1, p < 0.0001, d = 3.0"
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
- Prior influence on perception is stronger in autistic than neurotypical adults in a stable context, but not after a frequency-range change — related
- Autistic adults adjust their prior expectation more slowly than neurotypical adults after a change in stimulus frequency range — related
- Computational modeling shows a lower sensory/prior precision ratio in autistic adults in Exp. II and an opposite response bias across groups — related
- Autistic adults show more consistent (less variable) tactile detection thresholds than neurotypical adults — related
- Sensory adaptation occurs in neurotypical but not autistic adults in tactile detection — related
