Subclaims¶

q3 i? The typical reader group was faster to respond than the dyslexic group, responses were slower as presentation rates increased, and the Group X Condition interaction was not significant for reaction time. → Christodoulou JA 2014

Evidence¶

Christodoulou JA 2014¶

Christodoulou JA, Del Tufo SN, Lymberis J, Saxler PK, Ghosh SS, et al. (2014) Brain Bases of Reading Fluency in Typical Reading and Impaired Fluency in Dyslexia. PLoS ONE 9(7): e100552. https://doi.org/10.1371/journal.pone.0100552

q3 · i? · causal · r1

A 3x2 repeated measures ANOVA on in-scanner reaction time found significant main effects of Group and Condition, but the Group X Condition interaction was not significant (p = .15). Groups also did not differ on rates of response across conditions.

"The typical reader group was faster to respond than the dyslexic group as indicated by a significant main effect for Group [F(1,22) = 9.76, p,.005]. Responses were slower as presentation rates increased as shown by a significant main effect of Condition [F(2,21) = 49.06, p,.0001]. The Group X Condition interaction was not significant [F(2,21) = 2.10, p = .15]"
