BACKGROUND INFO 

											*Purpose*
This script implements the a task of unsolvable anagrams based on 
Feather, NT & Simon, JG (1971). Attribution of responsibility and valence of outcome in relation 
to initial confidence and success and failure of self and other. Journal of Personality
and Social Psychology, 18, 173-188.


											  *Task*
Participants are asked to solve anagrams. The difficulty of the practice as well as test items
is manipulated.											  


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

(1) Raw data file: 'UnsolvableAnagrams_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 
/practiceDifficulty:			1 = easy practice; 2 = difficult practice
/testDifficulty:				1 = easy test; 2 = difficult test
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) 
stimulusitem:					the presented stimuli in order of trial presentation
/correctAnswer:					stores the correct answer to the anagram
response:						the participant's response (as recorded)
/response:						stores the response (as used for analysis of accuracy)
correct:						the correctness of the response (1 = correct; 0 = incorrect)
latency: 						the response latency (in ms)
/countAttempted:				counts the number of attempted anagrams during the test


(2) Summary data file: 'UnsolvableAnagrams_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)
/practiceDifficulty:			1 = easy practice; 2 = difficult practice
/testDifficulty:				1 = easy test; 2 = difficult test
/countAttempted:				counts the number of attempted anagrams during the test
/propCorrect_practice:			proportion correct solved anagrams during practice
/propCorrect_test:				proportion correct solved anagrams during test
/meanRT_test:					mean lateny of correctly solved anagrams during the test phase
/passORfail:					if more than 7 anagrams were solved correctly during the test phase, the test is passed (otherwise fail)


EXPERIMENTAL SET-UP

4 experimental conditions (assignment by groupnumber):
group1 = easy practice, easy test
group2 = easy practice, difficult test
group3 = difficult practice, easy test
group4 = difficult practice, difficult test

Practice Block:
* 5 anagrams (order is randomly determined)
* timeout for each anagram: 
* feedback after each anagram for 500ms	

Test Block:
* 25 anagrams (order is randomly determined)
* timeout for each anagram:
* feedback after each anagram for 500ms

STIMULI
see section Editable Stimuli
* Practice Items are taken from Feather & Simon (1971)
* 25 test items each for difficult and easy test condition were generated by Millisecond Software.
Note: these test anagrams are untested. You can easily substitute your own.
Note: 1/5 (=5) anagrams for the difficult condition are unsolvable English anagrams

INSTRUCTIONS
see section Editable Instructions
Instructions are not original and can be easily edited.

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:

/anagram_fontsize:					the size of the anagrams in canvas height percentage (default: 5%)
/practiceTimeout:					the timeout for practice items in ms (default: 30000)
/testTimeout:						the timeout for test items in ms (default: 30000)
