BACKGROUND INFO

											*Purpose*
This script offers an adaptation of the Finger Tapping Test (aka Finger Tapping Oscillation Test) - FTT- for the computer. The FTT is a 
test of self-directed motor-speed.

											  *Task*
Participants are instructed to tap the SPACEBAR with either the index finger of their dominant or non-dominant hand 
as often as they can within a 10s time period (=default). The 10s time period starts with the first tap. Valid taps are those
that occur within that 10s time period.

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

(1) Raw data file: 'FingerTapping_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 															
values.dominanthand:			whether the dominant (1) or the non-dominant hand (0) is tested
values.blockcount:				keeps track of the number of blocks run for each hand
values.tapcount:				counts the valid taps in each round (=score)
values.rank1-values.rank10		the ranking of the scores
values.FinalScore				the final score for the current hand
values.score_dominant:			the final score for the dominant hand
values.score_nondominant:		the final score for the non-dominant hand

values.restperiod:				the duration of the restperiod after a round
parameters.maxdifference:			the max difference in scores of the five scores used to calculate final score
parameters.blocklength:				the duration of a block ("round") - after the first tap


(2) Summary data file: 'FingerTapping_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 (script was aborted prematurely); 1 = script was completed (all conditions run)
values.score_dominant:			the final score for the dominant hand
values.score_nondominant:		the final score for the non-dominant hand



EXPERIMENTAL SET-UP
Scoring: 							Participants run through a mandatory number of 5 rounds (=blocks). The scores (=number of taps) get ranked from lowest to highest
									If the scores of these 5 rounds are within 5 (=default) taps of each other, the final score is the mean tapping score.
									If the score of these 5 rounds are not within 5 taps of each other, an additional block is run, until 5 scores can
									be found that are within a 5-point range (checking starts from the 5 highest ranked scores to the lowest ranked scores).
									The final score is the mean of these 5 scores. 
									The maximum number of rounds is 10. If no 5 scores can be found that are within a 5 point range from each other,
									the final score is the mean of all 10 tapping scores. A separate score for the dominant and the non-dominant hand is kept.

Order:								Testing starts with a practice round, followed by 5-10 testing rounds with the dominant hand and ends
									after 5-10 rounds of testing with the non-dominant hand.
									After each round of testing, participants receive feedback and get at least a 10s (=default) rest period. 
									After every 3 (=default) testing rounds, this resting period is increased to 60s (=default).		

INSTRUCTIONS
see section Editable Instructions

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.

The parameters you can change are:

maxdifference:						the maximal difference between 5 consecutive scores (default is 5)
blocklength:						determines the length of the block (default: 10s)
longrestperiod:						determines how long the restperiod is after block3 (and block6)
regularrestperiod:					determines the regular restperiod after a block
longrestperiodblock:				determines after how many blocks there should be a longer restperiod (default: after every 3 testing blocks)
