Hand dexterity impairments in patients with stroke reduce activities of daily living (ADL) and quality of life. Visuospatial ability is associated with motor learning, but this has not previously been reported in patients with subacute stroke. We aimed to investigate whether visual terminal feedback (FB) affected motor learning of hand dexterity and the relationship among visuospatial ability. Overall, 17 subacute stroke patients (age: 66.1 ± 13.8 years) with mild upper limb motor impairment were included. The experimental task was the grasping force control task. The visuospatial task was the Rey–Osterrieth Complex Figure Test (ROCFT). The experimental protocol was conducted in 2 consecutive days: day 1 consisted of a pre-test (PRE), practice, and short-term retention test (SRT), and day 2 consisted of a long-term retention test (LRT) and the ROCFT. Grasping errors were significantly decreased in the SRT and LRT than in the PRE. Furthermore, ROCFT scores (copy and recall) and LRT grasping errors were moderately negatively correlated (ρ = -0.51 and − 0.53). In conclusion, visuospatial ability is an important factor associated with motor learning in subacute stroke patients. Future studies should use visual terminal FB, and training programs for visuospatial ability should be considered in stroke rehabilitation. [ABSTRACT FROM AUTHOR]

AbstractMany individual difference variables predict Bayesian reasoning performance, including cognitive reflection (thoughtful engagement with a problem rather than intuitive responding). The cognitive reflection test (CRT), though, is interdependent with numerical literacy. Two non-mathematics versions of this test (CRTverbal) are integrated and evaluated here, concurrent with other individual difference measures, as predictors of Bayesian reasoning performance. Two studies found CRTverbal appears to measure a fairly unitary underlying construct that is correlated with Bayesian reasoning performance. However, all other measures were also correlated with Bayesian reasoning, as well as generally with each other (including numerical literacy correlating with CRTverbal). Stepwise regressions found that Bayesian reasoning was best predicted by visuospatial ability and sets reasoning ability, excluding numeracy, working memory (Experiment 1), and pattern extrapolation abilities (Experiment 2). Although cognitive reflection remains a predictor of some utility, these positive manifold patterns of results suggest a broader cognitive ability may be generating these results.

Objective: Visuo-spatial ability (VSA) plays a role in preoperative planning, anatomical navigation and decision-making during surgery. This study aimed to test hypothesis that a correlation link existed between VSA and the speed of execution of a complex surgical task., Method: The study was carried out on 49 students just before starting their surgical internship, at Lille Medical Faculty in October 2023. They answered a biographical questionnaire including confounding factors on VSA, then completed the Mental Rotation Test - A (MRT-A). They were timed on two separate tasks: conforming a titanium plate to mandibular angles on a 3D printed model, and excising a lesion from the helix of a silicone cast ear model, followed by a reconstruction using a "small ear" flap., Results: A weak correlation between the MRT-A score and the time required to complete the right and left plates conformation (r = -0.377, p = 0.007; r = -0.349, p = 0.014 respectively). There was a moderate correlation between the MRT-A score and the time required to complete the entire plate conformation workshop (r = -0.457, p = 0.001). There was no significant correlation between the MRT-A score and the time required to complete the ear workshop (r = -0.127; p = 0.375). A significant regression equation was found [F(2,48) = 104.960; p < 0.0001)], with a R 2 of 0.814., Conclusion: A correlation was found between VSA and the speed of a conformation of titanium plate on mandibular angle, but no link was established between speed and performance of a complex surgical task on flapless excision suture workshop., Competing Interests: Declaration of competing interest The authors declare that they have no conflicts of interest., (Copyright © 2025 Royal College of Surgeons of Edinburgh (Scottish charity number SC005317) and Royal College of Surgeons in Ireland.
