q2 i3 A positive correlation between digit span and phonemic fluency was present in the congenitally blind group but absent in the sighted group. → Occelli Valeria 2017

q2 · i3 · associational · r2

Group-specific correlational analyses (Table 2A/2B). The congenitally blind showed a digit span–phonemic fluency correlation of "r = .58, p = .048"; the sighted group showed no such correlation.

"There was a positive correlation between digit span and phonemic fluency in the congenitally blind group (r = .58, p = .048) that was absent in the sighted group."
