Twenty-three participants met the inclusion criteria for the study with an average MoCA score of 24.70 (median = 25; Table 2). It has been suggested that a score below 26 is considered having cognitive impairment (Nasreddine et al., 2005). In the current study, fifteen participants' MoCA scores were lower than 26. The MoCA score was treated as a continuous variable for the following analyses. For the adaptation schedules, a modified “hot deck” imputation technique (Andridge & Little, 2010) was

摘要:
The current study examined the augmentation of error feedback on visuomotor adaptability in older adults with varying degrees of cognitive decline (assessed by the Montreal Cognitive Assessment; MoCA). Twenty-three participants performed a center-out computerized visuomotor adaptation task when the visual feedback of their hand movement error was presented in a regular (ratio = 1:1) or enhanced (ratio = 1:2) error feedback schedule. Results showed that older adults with lower scores on the MoCA had less adaptability than those with higher MoCA scores during the regular feedback schedule. Howev...
