Systematic Comparison of Brain Imaging Meta-Analyses of ToM with vPT

Table 2

Examples of typical tasks entering the vPT meta-analysis by Schurz et al. [10].

Author	Img.	Experimental task	Control task
		Level 1 visual perspective taking
Vogeley [47]	fMRI	You see a scene including an avatar and a number of objects. Indicate how many objects the avatar can see.	You see a scene including an avatar and a number of objects. Indicate how many objects you see.
		Level 2 visual perspective taking
Aichhorn [9]	fMRI	You see a scene including an avatar and two objects. Indicate their relative spatial arrangement, for example, “block is in front of the pole” from the viewpoint of an avatar.	You see a scene including an avatar and two objects. Indicate their relative spatial arrangement, for example, “block is in front of the pole” from your own viewpoint.
		Level 2 imagined viewer rotation
Zacks [48]	fMRI	You see an array of four objects. Imagine viewing the array from a different angle (i.e., imagine a self-rotation around the array). Indicate if a particular object is now on the left or right side of the array.	You see an array of four objects. Imagine that the array rotates along its vertical axis, while your own position remains the same. Indicate if a particular object is now on the left or right side of the array.
