Ghost Puzzle

Participants have to pick which one of two puzzle pieces would fit into a hole on a board. Pieces depict ghost – one is identical to the outline of the hole and one is a mirror versions thereof. Stimulus orientation varies in 30deg steps (Frick et al. 2013). A paper-pencil version for group testing (Frick & Pichellmann, 2023) shows rows of rotated ghost that have to be compared to a standard; in a computerized version (GNU Octave 4.0.0), participants pick one of two holes on a tablet computer, in which a depicted ghost would fit.
