BACKGROUND INFO
										
											  *Task*
Participants are asked to evaluate linguistic target sentences either on Likert scales or/and by
Magnitude Estimations (ME).

The sentences are presented visually.


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

(1) Raw data file: 'LinguisiticAcceptabilityJudgments_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 subjectnumber 
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) 
/judgmenttype:					"Likert" vs. "Magnitude Estimation"
/stimulus:						contains the current stimulus (for practice lines: the relative length of the target line)
response:						the participant's response (depends on task)
correct:						the correctness of the response (1 = correct; 0 = incorrect)
/log_MEjudgments:  				log transform of the magnitude judgment (if applicable)
latency: 						the response latency in ms


(2) Summary data file: 'LinguisiticAcceptabilityJudgments_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)


EXPERIMENTAL SET-UP
Likert Method:
* each likert trial presents a randomly selected target sentence (random selection without replacement)
with a 5 point Likert scale and the following anchors: "extremely unnatural" to "extremely natural"
	=> to change number of anchors and anchors go to TRIALS -> likert.LAJ_likert and follow further instructions
* the Likert Method runs as many trials as specified under parameters.nr_judgments (editable parameter)

Magnitude Estimation
* each magnitude estimations presents the baseline sentence and a randomly selected target sentence (random selection without replacement)
as well as a textbox to collect the judgments
* the Magnitude Estimation Method runs as many judgments as specified under parameters.nr_judgments (editable parameter)


STIMULI
* the baseline sentence for Magnitude Estimations can be set under section Editable Stimuli-> item.me_baselinesentence
* the target sentences can be set under section Editable Stimuli -> item.target_sentences
	(also set parameters.nr_judgments under Editable Parameters)


INSTRUCTIONS:
* instructions can be edited under section Editable Instructions
=> LIKERT: item.likert_instructions
=> MAGNITUDE ESTIMATIONS:
	a) item.me_instructions
	b) page.me_practice & page.me_test	


EDITABLE CODE:
check under EDITABLE CODE 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:

/LikertMethod:						true = Likert Acceptability Method is run (default)
									false = Likert Acceptability Method is NOT run

/MagnitudeEstimation:				true = Magnitude Estimation Acceptability Method is run (default)
									false = Magnitude Estimation Acceptability Method is NOT run

/nr_judgments:						specifies the number of judgments to be made (default: 4)
/fontsize_stimulus:					sets the size of the stimulus in percentage of screen height (default: 5%)
/baselinelength:					the baseline line length in screen height proportion for ME practice (default: 25%)
