I'm doing a research experiment where I'm trying to measure the time it takes for participants to answer certain questions in an online questionnaire/survey. More specifically, I will be asking participants to examine a graphic image and answer a question about it. An important part of this research is recording how long it takes participants to respond. Any suggestions are welcome, thanks!
Here are a couple of suggestions:
Inquisit records the timing of each response and can be run online. If you care about timing a lot and you need to run the study online, then this is quite a good option.
Qualtrics can record various features of survey delivery time. In particular, you can record time spent on each survey page. If you have one question per page, this can approximate time to respond to the item. This can be useful if you want to identify participants who are not reading items. However, I wouldn't use Qualtrics for cognitive reaction time based experiments. Note also that in order to record item response times you need to manually set this for each survey page.
There are specific metrics that test latency of response, e.g., the Stroop Test. The basic idea behind this test is to expose subject to a colored square, e.g., a red patch, and then measure how long it takes them to associate the word "red" with the stimulus.
The Stroop effect is one of the most widely replicated findings in cog sci.
