BACKGROUND INFO

											*Purpose*
This script implements the Implicit Positive and Negative Affect Test (IPANAT) as described in:

Quirin, M., Miguel Kaze´n, M., & Kuhl, J. (2009). When Nonsense Sounds Happy or Helpless: The Implicit Positive 
and Negative Affect Test (IPANAT). Journal of Personality and Social Psychology, 97, 500–516.


											  *Task*
Participants are presented 6 surveypages for 6 nonsense words. Each surveypage
contains 6 Likert Scales: 3 scales to rate how well positive adjectives
describe the current nonsense word and 3 scales to rate how well negative adjectives
desribe the current nonsense word.



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

(1) Raw data file: 'IPANAT.iqdat'

date, time, group, subject:		date and time script was run with the current group/subjectnumber 
build:							the Inquisit build 

q*_response:					response given (in assigned values)									
q*_latency:						how much time the participant spent on the surveypage with this particular question
								(the last time this particular surveypage was visited)

								
(2) Summary data file: 'IPANAT_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)
/meanPA1-
/meanNA3:						Mean rating for each of the 6 adjectives	(P = positive, N = negative)
									=> the higher the mean ratings the more participant judged the particular positive/negative adjectives 
								to 'describe' the nonsense words.

/meanPA:						Mean rating for the Positive adjectives
									=> the higher the mean rating the more participant judged positive adjectives to 'describe' the nonsense words.
/meanNA: 						Mean rating for the Negative adjectives						
									=> the higher the mean rating the more participant judged negative adjectives to 'describe' the nonsense words.


EXPERIMENTAL SET-UP
(a) 6 surveypages shown in the following order
1. SAFME
2. VIKES
3. TUNBA
4. TALEB
5. BELNI
6. SUKOV

* To randomize the order of the surveypages, go to section SURVEY and follow instructions.

(b) the order of the adjectives is the same for all nonsense words:
pos1 -> neg1 -> pos2 -> neg2 -> pos3 -> neg3

To randomize the order of the adjectives, go to section SURVEYPAGES and follow instructions.

STIMULI
The adjectives can be edited under section EDITABLE STIMULI

INSTRUCTIONS
Instructions are original and are presented via an html page

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.
