Are there “neglect plus” syndromes to be identified?

Abstract

Spatial exploration requires multiple simultaneous processes and it seems hardly surprising that damage to many of them may give rise to asymmetric spatial behaviour. A distinction has been suggested between directional hypokinesia of arm movements and “perceptual” neglect (Tegnér & Levander, 1991a), and we should probably also distinguish directional hypokinesia of eye movements. Although the experimental evidence in favour of these distinctions at present seems relatively good, it is still uncertain whether what we observe is the result of fractures along natural cleavage lines or if they are “stress” fractures that are consequently less relevant for the understanding of normal spatial cognition.
