BACKGROUND INFO
___________________________________________________________________________________________________________________
This script implements Millisecond Software's computerized version of the Money Road Map Test,
a test of directional sense in a 2D environment.
Researchers can select to run the task with an absolute screen size to ensure that distances
stay the same across devices. The default settings default to proportional sizing
See section Defaults for more info.

TASK DESCRIPTION
___________________________________________________________________________________________________________________
Participants are instructed to drive a little blue car on a fixed route through a town.
The car automatically stops at each intersection and participants are instructed to choose the
appropriate turn signal for the turn the car is about to make.
The test provides a short practice with 3 intersections and a test with 32 intersections.

DURATION
___________________________________________________________________________________________________________________
the default set-up of the script takes appr. 5 minutes to complete
___________________________________________________________________________________________________________________
DATA OUTPUT DICTIONARY
___________________________________________________________________________________________________________________
The fields in the data files are:
(1) Raw data file: 'roadmaptest_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: with the current subject id
group: with the current group id
session: 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.
phase: 1 = practice
2 = test
numberPracticeBlocks: stores the number of practice blocks run
intersection: stores the current intersection
response: stores the response made (leftSignal vs. rightSignal)
corrResp: stores the correct response (left vs. right)
correct: 1 = the response was correct; 0 = otherwise
latency: the response latency (in ms); measured from onset of response buttons
list.acc.mean: the proportion correct responses in the current block
(2) Summary data file: 'roadmaptest_summary*.iqdat' (a separate file for each participant)
inquisit.version: Inquisit version run
computer.platform: the platform the script was run on (win/mac/ios/android)
startDate: date script was run
startTime: time script was started
subjectId: assigned subject id number
groupId: assigned group id number
sessionId: assigned session id number
elapsedTime: time it took to run script (in ms); measured from onset to offset of script
completed: 0 = script was not completed (prematurely aborted);
1 = script was completed (all conditions run)
///practice:
numberPracticeBlocks: the final number of practice blocks run
practiceAcc: the final proportion correct practice performance (three intersections), before moving on to the test
numberIntersections: the number of intersections travelled (for completed test that should be 32)
numberCorrectResponses: the number of correct responses made
propCorrectResponses: proportion Correct responses
meanRT: mean response time (in ms) (regardless of accuracy)
meanCorrRT: mean correct response time (in ms)
sdCorrRT: standard deviation of correct response times (in ms)
___________________________________________________________________________________________________________________
EXPERIMENTAL SET-UP
___________________________________________________________________________________________________________________
1. Intro: by default the instructions are given visually and aurally (optional)
2. Practice: the practice block is run max. 2 times (editable parameters) before the test is started
It's repeated, if participants are below parameters.minPracticeAcc (default: 1.0)
The practice provides visual and auditory feedback and requires participants to correct
wrong choices. Practice also provides response reminders if no response is detected within a certain time
frame (default: 3000ms)
3. Test:
- 32 intersections
- car stops automatically at each intersection and participants have to choose from a left or right
turn signal (located left and right of the map)
- once selected, the selected turn signal blinks for a couple of times before the car starts moving again
- no feedback is provided
4. OPTIONAL performance feedback (see parameters.performanceFeedbackSetting)
The default feedback gives participants the choice whether to get performance feedback or not.
If they choose to see it, the little blue car drives once more through the city and leaves
the letter R and L at each intersection to reflect the response made by the participant.
Red letters indicate that the response was incorrect.
Green letters indicate that the response was correct.
Participants have as much time as they want to check the performance map.

Note: the script could be adapted to run customized maps as well

INSTRUCTIONS
___________________________________________________________________________________________________________________
provided by Millisecond Software - can be edited under section 'Editable Instructions'
The instructions are not original.
Audio instructions are optional and can be turned off. They were created with the help of the
Google Translate fairy and Audacity.

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:
//color parameter
/ canvasColor = black //Display color of the actively used portion of the screen (the 'canvas')
//Note: if set to a color other than the screenColor, the active canvas
//appears 'anchored' on the screen regardless of monitor size
/ screenColor = black //Color of the screen not used by the canvas ('inactive screen')
/ defaultTextColor = white //Default color of text items presented on active canvas
/ skipDirectionLabels = false //true = only the turn signal buttons are presented
//false = prints "LEFT" and "RIGHT" above the turn signal buttons
/ skipAudioInstructions = false //true: the instructions are only presented visually
//false: the instructions are presented visually as well as aurally
/ performanceFeedbackSetting = 1 //0: participants will get performance feedback
//1: participants get the choice to get performance feedback
//2: participants will not get performance feedback
//practice parameters
/ minPracticeAcc = 1.0 //the minimum practice performance
/ maxPracticeBlocks = 2 //the maximum number of times the practice block is run before
//the test drive begins (regardless of practice performance)
//timing parameters
/ reminderOnsetTime = 3000 //onset time (in ms) of a response reminder (if no response has been made in the meantime)
//practice only
