___________________________________________________________________________________________________________________ Vividness of Visual Imagery Questionnaire 2 (VVIQ2) Demographic Questionnaire and Opinion Survey ___________________________________________________________________________________________________________________ Script Author of original Inquisit VVIQ script: Adnan Niazi (Donders Institute for Brain, Cognition and Behaviour, Radboud University Nijmegen) last updated: 03-02-2022 by K. Borchert (email@example.com) for Millisecond Software, LLC The VVIQ2 script builds on the original Inquisit VVIQ.script. ___________________________________________________________________________________________________________________ BACKGROUND INFO ___________________________________________________________________________________________________________________ This script implements the VVIQ 2 by Marks, D.F. (1995). New Directions for Imagery Research. Journal of Mental Imagery, 19, 153-167. ___________________________________________________________________________________________________________________ OVERVIEW ___________________________________________________________________________________________________________________ participants rate with eyes closed the vividness of 32 imagined scenes on a 5-point scale (a glider is used in this script). (8 scenes with 4 questions each) Each response receives 1 (lowest vividness) to 5 (highest vividness) points. (Note: the VVIQ2 questionnaire reverses the scales compared to the VVIQ questionnaire) Max combined score = 5*32 = 160 (high vividness) Min combined score = 1*32 = 32 (low vividness) ___________________________________________________________________________________________________________________ DURATION ___________________________________________________________________________________________________________________ the default set-up of the script takes appr. 6 minutes to complete ___________________________________________________________________________________________________________________ DATA FILE INFORMATION ___________________________________________________________________________________________________________________ The default data stored in the data files are: (1) Raw data file: 'vviq2*.iqdat'(a separate file for each participant) date, time: date and time script was run with the current group/subjectnumber subject, group, session: with the current subject/groupnumber/session id build: the Inquisit build q*_response: response given (in assigned values) Scale: 1 (no image at all)- 5 (perfectly clear and vivid) q*_latency: how much time (in ms) the participant spent on the surveypage with this particular question (the last time this particular surveypage was visited) (2) Summary data file: 'vviq2_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) demographics: textbox.age.response: age response of participant radiobuttons.gender.response: gender response of participant textbox.occupation.response: occupation response of participant vviq2_total: Range 32 (low ability to imagine) -160 (high ability to imagine) Note: the higher the score, the higher the ability to imagine ___________________________________________________________________________________________________________________ INSTRUCTIONS ___________________________________________________________________________________________________________________ The htm instruction pages are provided by Millisecond Software (build on the instructions by Niazi). They were written to closely resemble the original instructions for the VVIQ (at: http://web.archive.org/web/20080615154210/http://www.staff.city.ac.uk/d.marks/vviq.htm) while adapting them to the computerized set-up used in this script. ___________________________________________________________________________________________________________________ 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.
