Visuo-Spatial research

Complex Figure drawings from Solms, Turnbull, Kaplan-Solms & Miller (1998)

Rey Figures from Turnbull,Beschin & Della Sala (1997)



Before my work on emotion, I worked in the domain of visuo-spatial cognition and object recognition.The most prominent of the findings was the disorder often described as 'orientation agnosia': in whichneurological patients have a sound knowledge of the relative internal spatial properties of an object, butlack knowledge of object orientatiion. It is closely associated with the clinical sign of rotated drawing(see Solms et al., 1998). This section has only some of the papers on visuo-spatial topics -mainly themore recent ones, which are on pdf.
