9 Is Always on Top: Assessing the Automaticity of Synaesthetic Number-Forms

For number-form synaesthetes, digits occupy idiosyncratic spatial locations. Atypical to the mental number line that extends horizontally, the synaesthete (L) experiences the numbers 1-10 vertically. We used a spatial cueing task to demonstrate that L's attention could be automatically directed to locations within her number-space--being faster to detect targets appearing in synaesthetically cued locations. We sought to eliminate any influence of strategy on L's performance by: (a) shortening the cue-target onset to 150 ms, (b) making the cues counterpredictive, and (c) instructing L to use an opposing strategy. If L's performance was attributable to intentionally using the cue to predict target location, these manipulations should eliminate any cuing effects consistent with her synaesthesia. However, L showed an attentional bias compatible with her number-form, except when explicitly instructed of the opposing strategy and given enough time (800 ms). Therefore, we attribute L's resilient cueing effects to the "automaticity" of her number-form. (Contains 3 figures and 4 tables.)
