BACKGROUND INFO

											*Purpose*
This script implements the Spatial Relations Task as used in

Salthouse, T.A. (2006). Mental Exercise and Mental Aging. Evaluating the Validity of the ‘‘Use It or Lose It’’ Hypothesis.
PERSPECTIVES ON PSYCHOLOGICAL SCIENCE, 1, 68-87.

											  *Task*
Participant gets one figure in a 2-D representation and has to choose amongst 4 possible 3-D figures the one that 
corresponds to the 2-D representation.


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

(1) Raw data file: 'SpatialRelations_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 subject/groupnumber 
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; by default data is collected unless /recorddata = false is set for a particular trial/block) 
/timelimit:						time allotted for the main task in ms (default: 10min, in ms)
/target:						contains the current target									
/choice1 - choice4:				contains the current stimulus for choice1-choice4									
/correctchoice:					stores the current correct choice
response:						the participant's response
correct:						the correctness of the response (1 = correct; 0 = incorrect)
latency: 						the response latency (in ms)
/sum_correct:					sums up the correct choices

(2) Summary data file: 'SpatialRelations_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)
/timelimit:						time allotted for the main task in ms(default: 10min, in ms)
/timereminder:					a reminder that only (default) 1 min are left (in ms)
/timeshowselection:				time the selection is briefly highlighted with blue stimulus (default: 50ms)
									!Note: that time 'takes away' from the allotted 10min
/sum_correct:					sums up the correct choices								


EXPERIMENTAL SET-UP

1 Testblock with 20 trials (trial.spatialrelations):
trial.spatialrelations present 1 target 2-D picture and 4 possible 3-D answer choices and a clock in the upper left hand 
corner. The clock counts down the allotted time (default: 10min). Once the selection is made a blue circle briefly highlights 
the selection. If the time is running out (default: 1 min or less) a red oval appears around the clock to
highlight the remaining time.

1 instruction block presents 2 demonstration examples.

STIMULI
To change the selection of Stimuli go to section Editable Stimuli
Note: list.correctanswers contains the corresponding correct answers

INSTRUCTIONS
To edit instructions go to section 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:

/timelimit:						time allotted for the main task (default: 10min, in ms)
/timereminder:					a reminder that only (default) 1 min are left (in ms)
/timeshowselection:				time in ms the selection is briefly highlighted with blue stimulus (default: 50ms)
								!Note: that time 'takes away' from the allotted 10min
