rightScore: the sum of all "+" for the right hand
Note:
-a score of "2" adds 2 to the number of "+" for the right hand
-a score of "1" adds 1 to the number of "+" for the right hand
-a score of "0" adds 1 to the number of "+" for the right hand

QUESTIONNAIRE SET-UP & SCORING
___________________________________________________________________________________________________________________
10 5-point Likert choice questions that ask about handedness.
The response scale is selected to mimic "++" for indicating a 'strong' hand preference
and "+" for a simple hand preference .
No preference (0) leads to adding a "+" to either handscore. (see Oldsfield, 1971, p.99/112)

BACKGROUND INFO
___________________________________________________________________________________________________________________
This script implements the Headphone Check Procedure by Woods et al (2017).
The Headphone Check Procedure is intended to be easy over headphones but difficult over loudspeakers
due to phase-cancellation. This procedure can thus be used online for screening purposes for procedures that
require headphone usage.

- participants are asked to play the soundfiles are are asked to select a button that
corresponds to the soundfile that was the 'quietest'

EXPERIMENTAL SET-UP
___________________________________________________________________________________________________________________
(1) Intro*
(2) Practice: 8 trials
- 8 different images using 'surprise' and 'fear' as the emotions
- order of images randomly determined
(3) Test: 4 test blocks (see Editable Parameters)
- 16 images (4 per emotion: angerleft, disgustleft, happyleft, sadleft) are run twice per block = 32 trials
- order of images randomly determined (Note: the same image can be run consecutively)
Trial Sequence:
-Fixation Cross for 1000ms (editable parameter)
-image for 500ms (editable parameters)
-max response time: 10000ms (editable parameters)
*Note: the Inquisit script does NOT run a sizing procedure for the stimuli as done by Parker et al (2020)
The images are presented with a 7cm height (as based on the height the images roughly appeared
in the Parker et al, 2020, Chimeric Demo task after completion of the resizing procedure).
If the current screen is NOT big enough to present the image with these default dimensions,
the largest possible size for the current screen is created (the image size used is noted in the data files).

EXPERIMENTAL SET-UP
___________________________________________________________________________________________________________________
This script runs 4 rounds of alternating RH-LH (LH-RH) blocks.
The order depends on selected groupnumbers:
odd groupnumbers: start with RH
even groupnumbers: start with LH
Participants hear a 'start' sound and see a timer appear on the screen. They then have 30s to type as many
TUMB-sequences as they can with their right hand or type as many WRVX-sequences with their left hand
(depends on block). Incorrect Responses* get recorded, but script 'waits' for a correct response to
move ahead in the sequence.
Example: T U U M B (counts as a completed sequence)
*Incorrect Responses: by default => one of the three currently incorrected response keys was pressed
Should all keys be potentially valid responses, go to trial.drumming and follow instructions for
