Subclaims¶

q3 i3 The intra-individual standard deviation of detection threshold measures was much higher in NT than in ASD participants, indicating higher sensory precision in ASD on this second-order measure. → Sapey-Triomphe 2023

q3 · i3 · causal · r2

In Experiment I, each participant's detection threshold was measured four times; the ASD group's "intra-individual standard deviation" was far lower (0.01 ± 0.01 vs 0.06 ± 0.04), t(61) = 5.8, p < 0.0001, d = 1.46, with extreme Bayesian evidence for the difference.

"The intra-individual standard deviation of the four detection threshold measures was much higher in the NT group (0.06 ± 0.04) than in the ASD group (0.01 ± 0.01) ( t(61) = 5.8, p < 0.0001, d = 1.46"

Discussion¶

Learner Variables¶

• Learning Disabilities and Developmental Differences — predictor: learners who differ on it differ in outcomes
