Figure 1
From: Observation and imitation of object-directed hand movements in Parkinson’s disease
Stimulus videos depicted a human hand reaching for and moving a small cube between 3 of 4 possible positions spaced 150 mm apart (example shows sequence 4-2-1), following either a direct or elevated trajectory. Participants observed and then immediately imitated the sequence but without physically manipulating an object (the object was not present in their own movement space). Note that the circles and arrows indicating the sequence are shown for illustration only and no target markers were visible during the task. Example stimulus videos are available at https://osf.io/ysbrj/.
