<p>The enhanced processing account posits a close connection between visual perceptual ability and memory. This account finds support in studies involving special populations with conditions based on neural changes in the ventral visual pathway, such as grapheme-color synesthetes and color experts. Research has shown that these groups possess a distinct profile of enhanced perception and memory where they demonstrate better performance in perceiving colors and spatial contrasts, as well as recalling the color of objects (i.e., features that bias the ventral visual pathway), compared to the general population. However, complementary predictions of the enhanced processing account regarding special populations with conditions based on neural changes in the dorsal visual pathway, such as sequence-space synesthetes and spatial experts, remain to be explored. This study aims to comprehensively assess the enhanced processing account by testing grapheme-color synesthetes, sequence-space synesthetes, color experts, and spatial experts, categorizing participants as either synesthetes or experts. Moreover, they will be further classified as belonging to either the color domain (encompassing grapheme-color synesthetes and color experts) or the spatial domain (encompassing sequence-space synesthetes and spatial experts). Participants will complete three tasks involving visual perception and memory, using stimulus features to differentiate between the ventral and dorsal pathways: one biasing processing toward the ventral visual pathway (color feature) and the other toward the dorsal visual pathway (spatial feature). This approach will allow us to examine a double dissociation between domain and stimulus feature, where according to the enhanced processing account, we hypothesize that grapheme-color synesthetes and color experts will show better performance for the color feature while sequence-space synesthetes and spatial experts will show better performance for the spatial feature. Additionally, the results of this study will contribute empirical evidence towards theoretical accounts of perception and memory, such as the representational model which suggests a close connection between perception and memory processes.<br>&nbsp;<br>&nbsp;</p>

D. Samuel Schwarzkopf suggested: My working hours are currently very limited due to some personal circumstances so I'm not able to accept any editing or reviewing for the time being. While I realise this is scheduled for several weeks from now I cannot easily predict right now what my workload will look like then. It sounds like a potentially interesting study. , D.
