This script implements the VVIQ 2 by
Marks, D.F. (1995). New Directions for Imagery Research. Journal of Mental Imagery, 19, 153-167.
6 minutes
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.
( 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)
The htm instruction pages are provided by Millisecond (build on the instructions by Niazi).
They were written to closely resemble the original instructions for the VVIQ

while adapting them to the computerized set-up used in this script.
