Subclaims¶

q2 i3 In uncued conditions the AwD showed significant effects of set size, difficulty and a difficulty by set size interaction, while controls showed no main effect of difficulty or interaction. → Moores 2011

Evidence¶

Moores 2011¶

Moores, E., Cassim, R. and Talcott, J.B. (2011). Adults with dyslexia exhibit large effects of crowding, increased dependence on cues, and detrimental effects of distractors in visual search tasks. Frontiers in Psychology. doi:10.1016/j.neuropsychologia.2011.10.005

q2 · i3 · causal · r1

Two-factor ANOVAs on set size eight crowded vs sixteen displays in uncued conditions. Both groups showed significant set size effects (η2p =.37 controls; η2p =.44 AwD), but only AwD showed significant difficulty (η2p =.44) and difficulty by set size interaction (η2p =.50) effects.

"In uncued conditions, both the controls (F 1,15 =8.93, p<.01, η2p =.37) and the AwD (F 1,14 =10.89, p<.005, η2p =.44) showed significant effects of set size. The AwD also showed a significant effect of difficulty (F 1,14 =11.15, p<.005, η2p =.44) and a difficulty by set size interaction (F 1,14 =13.81, p<.005, η2p =.50)."

Discussion¶

Related Claims¶

• Adults with dyslexia show disproportionately reduced discrimination accuracy in crowded displays compared to controls — related
• AwD required significantly longer calibrated display durations than controls despite attempts to equate overall accuracy — related
• Adults with dyslexia use pre-cues to enhance discrimination accuracy, with pre-cued performance exceeding both post-cued and uncued conditions — related
• The four-way interaction between cue, group, display type and difficulty was significant, with group differences largest for uncued crowded stimuli — related
• Pre-cues and post-cues eliminate set size effects for controls but not for adults with dyslexia — related
