Sensitivity to gender, person, and tense inflection by persons with Alzheimer's disease.
This paper investigates sensitivity to gender, person, and tense inflection in individuals with Alzheimer's disease (AD) in on-line and off-line tasks. Fourteen persons with AD and 14 matched controls participated in two studies: sensitivity to gender incongruity was tested in an on-line reading task and sensitivity to violation of tense and person was tested with an off-line grammaticality judgement test. Group performance was comparable on both tasks. It is argued that patients' preserved sensitivity to these features is primarily a function of the simplicity of the required operations. The notion of simplicity in this context is discussed and various parameters are offered for future investigation.
