BACKGROUND INFO

											*Purpose*
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.

											  *Task*
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).


DATA FILE INFORMATION: 
The default data stored in the data files are:

(1) Raw data file: '_raw*.iqdat' (a separate file for each participant)

build:							Inquisit build
computer.platform:				the platform the script was run on
date, time, subject, group:		date and time script was run with the current subject/groupnumber 
blockcode, blocknum:			the name and number of the current block
trialcode, trialnum: 			the name and number of the currently recorded trial
									(Note: not all trials that are run might record data; by default data is collected unless /recorddata = false is set for a particular trial/block) 
/index:							contains the itemnumber of the current slide
/condition:						contains the condition tied to the current slide (e.g. cognitive, affective, physical)
/FaceExpression:				contains the facial expression of Yoni tied to the current slide (e.g. happy, neutral, sad)
/eyes:							contains Yoni's eye gaze in relation to the correct answer for the current slide (e.g. 'misleading', 'leading', 'non')									
/order:							1 = first order; 2 = second order
/Verbs:							contains the verbs used for the current slide
/correctanswer:					contains the correct answers tied to the current slide
/image:							contains the current image presented
response:						the participant's response
correct:						the correctness of the response
latency: 						the response latency (in ms)

(2) Summary data file: '_summary*.iqdat' (a separate file for each participant)

script.startdate:				date script was run
script.starttime:				time script was started
script.subjectid:				subject id number
script.groupid:					group id number
script.elapsedtime:				time it took to run script (in ms)
computer.platform:				the platform the script was run on
/completed:						0 = script was not completed (prematurely aborted); 1 = script was completed (all conditions run)
/propcorrect:					overall proportion correct
/meanRT:						overall mean correct latency (in ms)
/SD_RT:							overall standard deviation of correct mean latencies
/propcorrect_C: 				proportion correct in condition 'cognitive' (across orders and phases)
/meanRT_C:						mean correct latency (in ms) in condition 'cognitive' (across orders and phases)
/SD_RT_C:						standard deviation of correct mean latencies in condition 'cognitive' (across orders and phases)
/propcorrect_A: 				proportion correct in condition 'affective' (across orders and phases)
/meanRT_A:						mean correct latency (in ms) in condition 'affective' (across orders and phases)
/SD_RT_A:						standard deviation of correct mean latencies in condition 'affective' (across orders and phases)
/propcorrect_P: 				proportion correct in condition 'physical' (across orders and phases)
/meanRT_P:						mean correct latency (in ms) in condition 'physical' (across orders and phases)
/SD_RT_P:						standard deviation of correct mean latencies in condition 'physical' (across orders and phases)

EXPERIMENTAL SET-UP
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.

!!!Note: 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.

!!!Note: 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.

STIMULI/INSTRUCTIONS:
original Yoni-test with slides and instructions can be found at:

see section Editable Stimuli

EDITABLE CODE:
check below for (relatively) easily editable parameters, stimuli, instructions etc. 
Keep in mind that you can use this script as a template and therefore always "mess" with the entire code to further customize your experiment.
