The PNFA group performed significantly less well than the semantic dementia group on non-verbal design fluency, while the semantic dementia group performed significantly less well than the PNFA group on the concrete words component of the synonyms test.
Each model included age and gender as covariates, with the exception of the models for non-verbal design fluency and trail making since these are internally corrected for age and gender.
In neither the PNFA nor the semantic dementia group was performance on any experimental auditory task significantly associated with a contemporaneous measure of executive function (non-verbal design fluency).
We discuss verbal interaction design for increasing people's acceptance of robots.
Various aspects of executive function were assessed with five neuropsychological tests : Tower of London, Trail Making Test, Verbal Fluency, Design Fluency and Association Fluency.
After a 15 min digestive period, participants completed a variety of computer-based neuropsychological tests assessing word discrimination, verbal memory, design memory, attention span, reaction time, problem solving, and response variability.
Measures of change in verbal and design learning following surgery were calculated as postoperative − preoperative scores.
Verbal and design learning were assessed before and 4 months after surgery.
Although this corresponded to an improvement in performance on the Verbal and Design Fluency Tests, it also corresponded to a decline in performance on the Color-Word Interference test (CWIT).
