Table 1. Debriefing ratings.

Question	Rating (1-5 Likert scale)	Task	Mean ± SD
To what degree did you feel your mind was wandering, that you were thinking of things other than the task?	1 = no mind wandering…	Scene	1.20 ± 0.41
	5= always mind wandering	Array	1.35 ± 0.49
How difficult was it to imagine the objects on the grid?	1 = easy…5 = very difficult	Scene	1.75 ± 0.64
How difficult was it to imagine the objects on the grid?	1 = easy…5 = very difficult	Array	1.75 ± 0.72
How difficult was it to follow the cue’s instruction of where to imagine the objects on the grid?	1 = easy…5 = very difficult	Scene	1.2 ± 0.41
	1 = easy…5 = very difficult	Array	1.15 ± 0.37
Did you have any sense of 3D space during array trials? Please rate the extent to which you felt the image had a sense of depth.	1 = completely 2D…	Scene	4.3 ± 0.44
	5 = completely 3D	Array	1.55 ± 0.51
For the array trials, did you feel that you imagined the objects in a scene at all and tried to repress this?	1 = always repressed…	Array	4.55 ± 0.60
	5 = never had to repress	Array	4.55 ± 0.60

SD = Standard Deviation.
