This script runs the Yoni-Test to assess cognitive and affective ToM (Theory of Mind) based on:
Shamay-Tsoory, S.G. & Aharon-Peretz, J. (2007). Dissociable prefrontal networks for cognitive and affective theory of mind: A lesion study. Neuropsychologia, 45, 3054–3067.

10 minutes
Participants view slides with a Yoni face in the middle and 4 objects (and occasionally faces) in each of the 4 screen quadrants. Participants are encouraged to click the object that makes the most sense in relation to provided statements such "Yoni thinks of ___________" as well as Yoni gazes (or the gazes of faces next to the 4 objects).
3 judgment conditions:
1) Cognitive Judgments:
A) first order: Yoni is thinking of___________________; directed Yoni gaze towards target
B1) second order: Yoni is thinking of the fruit that ____________ wants; directed Yoni gaze towards target
B2) second order: Yoni is thinking of the fruit that ____________ wants; non-directed gaze (Yoni looks straight ahead)
2) Affective Judgments: (all possible combination of love/does not love)
A) first order: Yoni loves___________________; directed Yoni gaze towards target
B1) second order: Yoni loves the fruit that ____________ loves ; directed Yoni gaze towards target
B2) second order: Yoni loves the fruit that ____________ loves; non-directed gaze (Yoni looks straight ahead)
3) control condition: Physical Judgments: !gaze information not relevant for this condition
A1) first order: Yoni is next to__________; directed gaze but misleading
A2) first order: Yoni is next to__________; non-directed gaze (Yoni looks straight ahead)
B1) second order: Yoni is next to the fruit that ___________ is next to; directed gaze but misleading
B2) second order: Yoni is next to the fruit that ___________ is next to; non-directed gaze (Yoni looks straight ahead)
Script runs 3 phases:
Phase A: runs first order trials of condition "cognitive", "affective", and "physical"
in a mixed design (8 trials each).
Phase B: runs a mixture of first order "cognitive" and "affective" (4 trials each) trials and
second order affective trials (24) in a mixed design. Object categories differ from Phase A/C.
Phase C: runs second order trials of condition "cognitive" (24 trials), "affective" (12 trials), and "physical"
(6 trials) in a mixed design.
!!! The phases are coded independently of each other in this script.
This allows for increased flexibility in selecting the phases of interest.
By default, this script runs phaseA-phaseC in order. Changes can be made under
section EDITABLE PARAMETERS.
!!! By default, the order of the slides is predetermined (run in the same order as the original Yoni test)
and the same for each participant.
In this script, the order of the slides in each phase can be randomized under EDITABLE LISTS.
