BACKGROUND INFO 	
___________________________________________________________________________________________________________________	
This script runs a version of the Northwestern University Famous Faces (NUFFACE) Test published by:

Gefen, T., Wieneke, C., Martersteck, A, Whitney, K., Weintraub, S., Mesulam, M.M., & Emily Rogalski, E. (2013).  
Naming vs knowing faces in primary progressive aphasia. Neurology, 81, 658-664.

The Famous Faces Test tests recall and recognition memory for famous faces.

Note: this script assumes that a test administrator is present during testing.
The test administrator needs to score each response by a simple keyboard press (1,2, or 0).
The computer keeps track of the scores.
At the end of the test, the test administrator can enter all responses for checking and analyses purposes
(provided test administrator took notes throughout testing).

TASK DESCRIPTION	
___________________________________________________________________________________________________________________	
Participants are shown 20 faces of well-known people from the 20th century.
They are asked to do a recall test (name) and (if no recall happens) a recognition test of
what they remember about the person.
For each picture (recall and/or recognition), test administrator has to score the 
response by pressing 1, 2, or 0 on the keyboard. The key-press automatically advances to the next
task.

Scoring:

For Recall: Test Administrator has to decide whether the answer is worth
2 points: participant correctly names first and last name (an automatic recognition score of 2 is added) -> experimenter presses '2'
1 point: particant correctly names only first or last name (an automatic recognition score of 2 is added) -> experimenter presses '1'
0 points: participant does not correctly name first nor last name (recognition trial is started) -> experimenter presses '0'

For Recognition: Test Administrator has to decide whether the answer is worth
2 points: participant correctly names 2 or more facts  -> experimenter presses '2'
1 point:  participant correctly names 1 fact  -> experimenter presses '1'
0 points: participant does not correctly name any fact -> experimenter presses '0'

After participant is done, experimenter has option to enter the recall/recognition answers for later analysis.

DURATION 
___________________________________________________________________________________________________________________	
the default set-up of the script takes appr. 5 minutes to complete

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

(1) Raw data file: 'famousfacestest_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.
										
picturecount:						counts all the pictures presented
stimulusitem:						the presented stimuli in order of trial presentation

response:							the response scancode
										2/79 => key '1'  
										3/80 => key '2'
										11/82 => key '0'
										
latency: 							the trial latency (in ms)
picturescore:						the score for the current picture
totalscore:							the sum of all picturescores

(2) Summary data file: 'famousfacestest_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)
								
totalscore:							the sum of all picture scores


___________________________________________________________________________________________________________________	
EXPERIMENTAL SET-UP 
___________________________________________________________________________________________________________________
The 20 faces are drawn randomly without replacement.
trial.ff_recall: participants are asked to recall the name(s) of the person depicted in the picture
Depending on answer, test administrator presses 1, 2, or 0 on keyboard

trial.ff_recognition: if participant couldn't recall either first nor last name of the famous person,
participant is asked what she/he remembers about this person.
Depending on answer, test administrator presses 1, 2, or 0 on keyboard

STIMULI
___________________________________________________________________________________________________________________
black and white photographs ("downloaded freely from the internet", Gefen et al, 2013) of the 
20 famous people published in supplemental material by Gefen et al (2013).
The photographs are not the originals used by Gefen et al (2013). 
They are provided by Millisecond Software and can be edited/replaced under Editable Stimuli.

Note: the stimuli are culturally and cohort sensitive

___________________________________________________________________________________________________________________	
INSTRUCTIONS 
___________________________________________________________________________________________________________________	
instructions are not original to Gefen et al (2013). They are provided by Millisecond Software
and can be changed 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.

The parameters you can change are:

/responsestoring:				true: at the end of the test, experimenter can enter all recall/recognition responses given (for later analysis)-default
								false: experimenter is given the opportunity to enter all recall/recognition responses
