BACKGROUND INFO

											*Purpose*
This script runs the Manikin Test to test Spatial Orientation & Spatial Transformation described by:

UNIFIED TRI-SERVICE COGNITIVE PERFORMANCE ASSESSMENT BATTERY (UTC-PAB) I. DESIGN AND SPECIFICATION OF THE BATTERY. 
ENGLUND, C.E., REEVES. D.L., SHINGLEDECKER, C.A., THORNE, D.R., WILSON, K.P., & HEGGE. F.W. (1987).
REPORT NO. 87-10, NAVAL HEALTH RESEARCH CENTER, P 0 BOX 85122, SAN DIEGO, CALIFORNIA 92138
NAVAL MEDICAL RESEARCH AND DEVELOPMENT COMMAND, BETHESDA, MARYLAND (p.29)

											  *Task*
Participants view Manikins superimposed on either a red square or green circle that hold a red square in one hand
and a green circle in the other.  Manikins can be right side up or upside down, can face towards
participant ('forward') or face away from participant ('backward').
Participants have to decide as fast as possible if the manikin holds the shape that is congruent with 
the background (e.g. the red square) in the left or right hand and press corresponding keys on the keyboard 
(default: V for left; M for right).


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

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

build:							Inquisit build
computer.platform:				the platform the script was run on
date, time, subject:			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) 
/verticalorientation:			"U(pright)" vs. "D(ownside)" (aka standing on the head)
/horizontalorientation:			"F(orward)" vs. "B(ackward)"
									Forward facing => participant sees the front of the manikin
									Backward facing => participant sees the back of the manikin
/stimshape:						"C(ircle)" vs. "S(quare)"
/congruenthand:					"R(ight)" vs. "L(eft)"
stimulusitem:					the presented stimuli in order of trial presentation
response:						the participant's response (scancode of responsekey)
correct:						the correctness of the response
latency: 						the response latency (measured from onset of stimuli to pressing response button; in ms)

(2) Summary data file: 'ManikinTest_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)
/propcorrect:					proportion correct (testblocks only)

/count_total:					counts the total number of trials
/MeanRT_total: 					mean latency of all trials (in ms)
/STD_total:						standard deviation of latencies of all trials
/medianRT_total:				calculates the median of the sorted items (in ms)
/minRT_total:					stores the minimum latency (in ms)
/maxRT_total:					stores the maximum latency (in ms)
/range_total:					stores the range of latencies
(for total, correct, incorrect, righthand responses, lefthand responses)

EXPERIMENTAL SET-UP
Practice Block: by default runs 1 block of 16 trials (all possible combinations once)
with performance (accuracy) feedback for 1s
Test Block: by default runs 4 blocks of 16 trials (no performance feedback)

STIMULI
manikins provided by Millisecond Software (can be easily be exchanged for others under Editable Stimuli;
Note: the file names should be kept as they are used to extract condition information about the stimulus)
16 manikins: 2 vertical rotation (up vs. down) x 2 lateral rotation (forward vs. backwards) x 2 shape (circle vs. square) x 2 congruent hand (left vs right)
Manikins show facial features, buttons, slit pockets, belt buckle when forward (aka facing towards the participant)
Manikins show hair on the head, back pockets, no buttons and no belt buckle when backwards (when facing away from participant)

INSTRUCTIONS
Instructions provided use the ones published by Englund et al (1987)

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:

/responsekey:							scancode of the response key
											Note: scancodes under Tools -> Keyboard Scancodes (default: 57)
/responsekey_label:						label of the response key (default: )

/number_practiceblocks:					number of practice blocks to run (default: 1)
/number_testblocks:						number of testblocks to run (default: 4)

/practicefeedbackduration:				the duration of the feedbackstimulus (default: 1000ms)
