1. ABOUT THE DATASET
------------

Title: START project: data from two tablet-PC based tasks measuring social reward responsivity in a UK sample

Creator(s): Dubey, I.(1,2),and Chakrabarti, B.(1), on behalf of the START consortium.

Organisation(s): 1. University of Reading 2. University of Nottingham 
Rights-holder(s): University of Reading

Publication Year: 2022

Description: This dataset was collected in a public event for children in 2017. Children between ages 3-9 years were invited to take part in the study. Both tasks were presented on a tablet PC (Samsung 10.1 tablet SM P600) running the START app. Details of the app and the START project are available at the https://startproject.bhismalab.org

1)	Excel spreadsheet titled “ButtonTask2017”. This spreadsheet shows 
a.	Each row presented data from one participant with an unlinked ID 
b.	Each column presents a variable labelled on top 
c.	Column descriptions and codes are given on the same sheet 

2)	Excel spreadsheet titled “PrefLook2017”. This datasheet shows 
a.	Each row presented data from one participant with their unique ids 
b.	Each column presents a variable labelled on top 
c.	Column descriptions and codes are given on the same sheet.

3)	Excel spreadsheet titled “MatchedData2017”. This datasheet shows data for children for whom there is complete data on both the preferential looking and the button task.
a.	Each row presented data from one participant with their unique ids 
b.	Each column presents a variable labelled on top 
c.	Column descriptions and codes are given on the same sheet. 

4)	Zip folder titled “Preferential_looking_2017”
a.	The face of the participant was video recorded using the front camera of the tablet. This video feed was then processed using an adapted version of a gaze estimation algorithm (Bishain R. An Open-Source, Computing Platform-Agnostic, Calibration-Free Preferential Gaze Detection Approach for Social Preference Assessment. In: INSAR 2019 Annual Meeting [Internet]. IMFAR; 2019 [cited 2020 May 15] https://insar.confex.com/insar/2019/webprogram/Paper31575.html). Each file here is the csv file generated from the algorithm for each participant. 
b.	Column A in each file shows number of frames
c.	Column B in each file is empty 
d.	Column C in each file shows gaze location on X axis
e.	Column D in each file shows gaze location on Y axis
f.	Column E in each file shows gaze location as left, right, outside, or on the tablet. Row 1 gives the descriptors for this
g.	Column F in each file shows the timestamp for each frame. Please note each trial was 5 seconds long. First 4 trials had social stimuli appearing on the right side and the next 4 had social stimuli appearing on the left side. 

5)	Zip folder titled “Button_task_2017”
a.	This data was generated from participants playing the “choice task” on the tablet. Their touch responses were recorded through the task. The total number of touches to the green (social) stimuli and red (non-social/object) stimuli are presented in the rows 07 and 09 respectively. 
b.	Column A row 1 is empty
c.	Column A row 2 is the survey ID
d.	Column A row 3 is the name of the task
e.	Column A row 4 is the number of attempts made
f.	Column A row 5 is the name of file type as saved by the START app 
g.	Column A row 6 is the end time of data collection
h.	Column A row 7 is the total number of touches to the green (social) stimuli
i.	Column A row 4 is the information if the task was interrupted (False = not interrupted, True = interrupted)
j.	Column A row 9 is the total number of touches to the red (non-social) stimuli
k.	Column A row 10 is the height of the screen
l.	Column A row 11 is the width of the screen
m.	Column A row 4 is the start time of data collection
n.	Column A after row 13 is the colour of button touched
o.	Column B after row 13 is the accelerometer recording along the x-axis
p.	Column C after row 13 is the accelerometer reading along the y-axis
q.	Column D after row 13 is the accelerometer reading along the z-axis
r.	Column E after row 13 is the timestamp for each touch
s.	Column F after row 13 is the X coordinate of each touch
t.	Column G after row 13 is the Y coordinate of each touch
u.	Column H after row 13 is the Z coordinate of each touch (random number, and should be ignored)
