Spatial asymmetries in action, perception and representation
While patients with right parietal damage neglect the left side of stimuli, the intact-brain population shows a slight neglect of the right side – known as pseudoneglect. This leftward bias appears to share many features in common with neglect. For example, it can be based on object- and space-based coordinates and has vertical and horizontal dimensions. Recently, we have shown that pseudoneglect also occurs for the mental representation of lines, as revealed by mental number lines and alphabet lines. The leftward bias for these mental lines appears robust and is affected by manipulations such as prismatic adaptation. Finally, we have examined the effect pseudoneglect has on some real-life situations, such as questionnaire responses and collisions.
