Description
The PEBL Manikin test. A test of 3-D spatial reoreientation.
About This Test
Participants view a manikin figure shown in various orientations (forward/backward, upright/upside-down) holding targets in each hand. The task is to identify which hand holds a specific target (red square or green circle) while mentally rotating the spatial perspective. Responses are made using left and right shift keys corresponding to the manikin's hands.

Data Output
Creates manikin-<subnum>.csv with trial-by-trial data containing columns: subnum (participant code), block (block number or 'PRACTICE' for practice trials), trial (trial number), target (target type: 1=red square, -1=green circle), targetname (target description: 'redsquare' or 'greencircle'), forback (manikin orientation: 1=facing forward, -1=facing backward), updown (manikin rotation: 1=upright, -1=upside-down), hand (correct hand: 1=left, -1=right), handname (hand description: 'left' or 'right'), resp (participant response: '<lshift>' or '<rshift>'), time1 (trial start time in ms), rt (response time in ms), corr (trial accuracy: 1=correct, 0=incorrect).
