Dissociations between Imagery and Language Processing.

Abstract

Previous research has demonstrated that mental imagery is not a unitary, undifferentiated ability, but rather is composed of a set of sub-abilities. A computerized task battery was constructed to assess performance on four imagery abilities, namely: image generation, inspection, maintenance, and transformation. Two patients who suffered left-hemisphere brain damage were tested on this battery and their performance on it was compared to their performance on standard speech/language tests. In addition, their performance was compared to that of a control group. The most striking result was the relatively intact imagery abilities, which in some cases were equivalent to those of young, healthy college students. There was also a suggestion that posterior left hemisphere damage may adversely affect some imagery abilities, which is consistent with previous findings. (Author)
