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 i? ANCOVA showed no significant effect of visual status on spatial imagery performance between blind and sighted groups. → Occelli Valeria 2017
q3 i? ANCOVA showed no significant difference between blind and sighted groups on the haptic spatial memory task. → Occelli Valeria 2017 (2)
Evidence¶
Occelli Valeria 2017¶
Occelli Valeria, Lacey Simon, Stephens Careese, Merabet Lotfi B., Sathian K. (2017). Enhanced Verbal Abilities in The Congenitally Blind. Experimental Brain Research. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5436932/
q3 · i? · associational · r2
ANCOVA of spatial imagery (shape construction from four-digit strings in a 5 × 5 matrix) in 23 participants; one blind and one sighted participant were excluded for task difficulty. Blind "87.5 ± 3.6%" vs sighted "79.2 ± 3.2%", not significant.
"ANCOVA showed no significant effect of visual status on spatial imagery performance after filtering out the covariates (blind: 87.5 ± 3.6%; sighted: 79.2 ± 3.2%; F1,18 = 2.4, p = .14; Figure 4A)"

q3 · i? · associational · r2
ANCOVA of haptic spatial memory (Corsi-style 5 × 5 matrix with sandpapered cubes, tested behind a curtain) in the same 25 participants. Blind "70.6 ± 8.2%" vs sighted "68.3 ± 7.0%", not significant.
"There was similarly no significant difference on ANCOVA between the blind and the sighted on the spatial memory task after factoring out the covariates (blind: 70.6 ± 8.2%; sighted: 68.3 ± 7.0%; F1,20 = .1, p = .7; Figure 4B)"
