Localization of body parts in brain injured subjects.

The issues which were dealt with in this study were whether the determinants of failure in body part identification differed as a function of modality of stimulus presentation or as a function of response conditions, and whether such differences could be attributed to neurologically determined variables, or to a generalized disorder of awareness of body topology. No evidence was found to support any of these latter factors as an explanation for impaired body part identification. Rather it can be concluded that a common factor underlies success in identifying body parts under all conditions and that this factor is the strength and precision of the conceptual representation of individual body parts.
