I'm working on my Psychology thesis and need help programming the study. I need a simple program that would record respondents' answers in an online experiment (looks like a questionnaire with different questions and pictures) and measure reaction times (in milliseconds). I've been advised to use Javascript.
A detailed description of the project is attached, including the structure of the needed program (on page 2).
It's quite urgent as the program should be ready in less than a week (August 23).
Thanks a million for your help!
