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.
q1 i? The authors propose that blind individuals apply working memory resources to compute number-space congruency, whereas sighted congruency effects arise at the sensory level. → Salillas E 2009
Evidence¶
Salillas E 2009¶
Salillas E, Grana´ A, El-Yagoubi R, Semenza C (2009) Numbers in the Blind's ''Eye''. PLoS ONE 4(7): e6357. https://doi.org/10.1371/journal.pone.0006357
q1 · i? · causal · r1
Authors' interpretation in the Discussion, not a separately tested result: the P300 is described as reflecting attention allocation and maintenance of a representation in working memory, and the absence of N100 modulation in the blind as indicating number representation activation does not influence sensory target processing. No effect size is printed.
"Accordingly, blind individuals may have restricted processing of congruency to a cognitive level (P300), applying working memory resources to the computation of congruency."
Discussion¶
Learner Variables¶
- Sensory Integration — predictor: learners who differ on it differ in outcomes
Related Claims¶
- Number-size/location congruency modulates the cognitive P300 only in blind participants — a narrower finding that bears on this claim
- Number-size/location congruency modulates the early sensory N100 only in sighted participants — a narrower finding that bears on this claim
- In an auditory number-cue detection task, both blind and sighted adults detect targets faster on number-size/location congruent trials, with no group difference — related
- In catch trials, large numbers elicit greater right-hemisphere P300 positivity than small numbers — related
