- Firstly you will be asked for a linguistic descriptor of the relative length. We have consider five descriptors (Very Small; Small; Medium; Large; Very Large). The aim is to select one of these descriptors at first sign (avoiding too much effort - later you could change it).
- Later you will be asked for your own estimate (without measuring it) of the relative length (in percentage) by means of a Fuzzy Set (the detailled information about the design and interpretation of the Fuzzy Set will be shown to you at this time).
- Finally, in case your initial perception had been changed during the process you can readjust again the linguistic descriptor of its relative length.
PERCEPTIONS
This program has been register in Safe Creative . Download the program Perceptions
This experiment regards your perception about the relative length of different lines. On the top of the screen, we have plotted in fuchsia the longest line that we could show to you. This line will remain visible in the current position during all the experiment, so that you can have a reference of the maximum allowed length at any moment.
At each trial of the experiment we will show you a black line and you will be asked about its relative length (in comparison with the length of the reference fuchsia line):
Note: It should be interesting to obtain at least 30 trials of the experiment for each person. The trials can be made in different times/dates. You can close the program at any time, and the next time you open it the experiment will continue from the situation before you closed it.
Check SMIRE web page Perceptions - Data Base for a complete description of the fields of the whole Data Set (plain text file) as well as how to refer to it from your research works/manuscripts.
