It is not yet known whether with aphantasia show deficits in cognitive and neuropsychological tasks thought to relate aspects imagery, including Spatial Span, One Touch Stocking Cambridge, Pattern Recognition Memory, Verbal Memory Mental Rotation. Twenty congenital (VVIQ < 25) were identified matched on measures age IQ twenty typical imagery > 35). The only group differences found within visuo-spatial working memory tests slower performance Cambridge task during trials that had greater load. These results suggest profile people without does greatly differ from those when examined by group. However, observed apparent increased This raises questions about or represents function conscious experience.
