Replication Data for: The influence of hand depiction types on behavioural patterns in laterality judgments.

According to the Motor Simulation Theory, cognitive states such as kinesthetic motor imagery activate the motor system in a similar way to overt motor execution. Action simulation involved in motor imagery can be implicitly triggered when individuals unconsciously simulate an action, as is the case in Hand Laterality Judgement Task (HLJT). Studies employing the HLJT often use various depictions of hands, which may potentially influence behavioural measures such as response times. The present study recruited 70 younger adults who mentally simulated both realistic and line drawing representations of hands using the HLJT. The results indicated that (1) mental transformations were quicker with line drawing depictions than with realistic hands, (2) faster response times were observed for the back of the hand compared to the palm, and (3) when comparing line drawings to real hands, quicker response times were noted for 0° and 90°L orientations. The results suggest that when compared to line drawings, realistic hands have slower response times for both simple (0°) and challenging (90°L) mental transformations. Overall, behavioural measures may vary between realistic hands and line drawings, underscoring the importance of considering this distinction when utilizing the HLJT.
