From: Chronic stroke survivors underestimate their upper limb motor ability in a simple 2D motor task
No evidence that actual and estimated upper limb motor ability correlate in the more affected arm only
a) CR1 ratings were significantly lower in the more affected limb despite similar SR levels. Left panel: CR1 ratings and Right panel: SR for each difficulty level for both limbs. Averages and standard errors of the mean (SEM) were plotted as a line plot of the median values for each participant at each difficulty level (T100-T5) for both the more (pink) and less (blue) affected limb. * indicates significant differences between limbs.
b) Correlation between confidence about task success (median CR1 across all trial) and success rate (% of successful trials across all trials, SR). Left panel: CR1 and SR were not correlated in the more affected limb. Right panel: But were significantly related in the less affected limb.
c-d) A correlation analysis between Left panel: CR1 and FMA scores and Right panel: SR and FMA scores of the more affected revealed that neither are a function of motor ability in clinical assessments.
d) Correlating CR1 and CR2 revealed a non-significant result, highlighting that participants did not change their rating after reaching for the target (i.e., did not use end position to update their confidence about task success).
