BACKGROUND INFO 	
___________________________________________________________________________________________________________________	
This script implements the Children's Test of Nonword Repetition (CNRep) to measure phonological working memory 
as used by:

		Anderson, J.D,  Wagovich, S.A., & Hall, N.E. (2006). Nonword repetition skills in young children who do and do not
		stutter. J Fluency Disord, 31(3), 177–199.

The test was originally described in:

		Gathercole, S.E., Willis, C.S., Baddeley, A.D., & Emslie, H. (1994). The Children’s test of nonword 
		repetition: A test of phonological working memory. Memory; 2:103–127.

The described test (Anderson et al, 2006) uses a tape-recorded (randomly assembled) sequence of nonwords 
with each word being separated by a 4s time interval. If a child needed more time to respond, the tape was 
paused (Anderson et al, 2006). 

This script adapts this procedure to the computer with the following procedural differences:
- unlimited time to respond to each nonword (the response latency is measured). 
- As any utterance at the point of recording is taken as a response the experimenter has to accept the response
	by pressing the  to advance to the next nonword trial. By pressing , the experimenter has the option
	to repeat the previous trial.

TASK DESCRIPTION	
___________________________________________________________________________________________________________________
Participants hear made-up English words and have to repeat them out loud. Trials can be repeated if 
deemed necessary by experimenter.
A practice run presents made-up and real English words. 

___________________________________________________________________________________________________________________	
DURATION 
___________________________________________________________________________________________________________________	
the default set-up of the script takes appr. XXX minutes to complete
(if no task duration is provided, please contact Millisecond Software

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

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

build:							The specific Inquisit version used (the 'build') that was run
computer.platform:				the platform the script was run on (win/mac/ios/android)
date, time, 						date and time script was run 
subject, group, 					with the current subject/groupnumber
script.sessionid:					with the current session id

blockcode, blocknum:				the name and number of the current block (built-in Inquisit variable)
trialcode, trialnum: 				the name and number of the currently recorded trial (built-in Inquisit variable)
										Note: trialnum is a built-in Inquisit variable; it counts all trials run; even those
										that do not store data to the data file such as feedback trials. Thus, trialnum 
										may not reflect the number of main trials run per block. 

stimulusitem:					the presented stimuli in order of trial presentation
/stimulusindex:					helper variable that stores the index of the current stimulus

response:						the participant's response
latency: 						the response latency (in ms)
/rt:							combines reaction time (in ms) across trials that repeat a nonword

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

computer.platform:				the platform the script was run on (win/mac/ios/android)
script.startdate:					date script was run
script.starttime:					time script was started
script.subjectid:					assigned subject id number
script.groupid:					assigned group id number
script.sessionid:					assigned session id number
script.elapsedtime:				time it took to run script (in ms); measured from onset to offset of script
script.completed:					0 = script was not completed (prematurely aborted); 
								1 = script was completed (all conditions run)

EXPERIMENTAL SET-UP 
___________________________________________________________________________________________________________________	

* 1 Instruction Block
* 1 Practice Block
* 1 Experimental Block

EXPERIMENTAL BLOCK:
* 1 block a 40 trial sequences

EXPERIMENTAL TRIAL SEQUENCE:
trial.cnrep_nonwords -> trial.accept -> 	a) Spacebar: next trialsequence (new nonword)
											b) Enter: trial.repeatnonword -> trial.accept-> 	a) Spacebar: next trialsequence (new nonword)
																								b) trial.repeatnonword

*trial.cnrep_nonwords: the next nonword is chosen. Any utterance is recorded as the response
		* latency is recorded.
		* by default items are called in sequence (-> Gathercole et al., 1994), this can be changed under STIMULI-> sound.nonword
*Experimenter has control over whether to accept the current response or whether to repeat the trial

___________________________________________________________________________________________________________________
STIMULI
___________________________________________________________________________________________________________________
* 40 nonwords, 10 items each with 2, 3, 4 and 5 syllables

* sound files recorded by a male American English native speaker (NOT original); 
!!!IMPORTANT: the sound files provided with this script are only intended for DEMONSTRATION PURPOSES 
and we STRONGLY suggest using your own sound recordings.
* sound files can easily be exchanged under EDITABLE CODE -> Editable STIMULI-> item.nonwords
(as well as practice items: EDITABLE CODE -> Editable STIMULI-> item.practiceitems)

PRACTICE:
* 1 Block with 10 trial sequences
* 5 words and 5 nonwords (NOT original) make up the practice items
* practice stimuli are drawn in sequence (->fixed randomly assembled sequence)
* Practice trial sequence similar to experimental trial sequence

INSTRUCTIONS 
___________________________________________________________________________________________________________________	
* instructions are not original
* they can be easily edited under EDITABLE CODE -> 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.
