A Simple RT Task Interface

This form supplies you with a very simple experimental design interface. It is deliberately simple so that you can focus on the design of your task, the instructions, and the data. This is a "microscopic" version of how you would setup an RT task in a real lab, but it will also show you how to wrangle some simple data to get us started with real human behavioral data.

Below you can enter the stimuli that will be presented (randomly), the range of random inter-stimulus intervals, and the number of trials that will be run. When you click "Run Experiment...", the participant (or, you, while testing your experiment) will click the "respond" button when the appropriate stimulus appears in the window (according to the definition of your experiment). This setup is called a go/no-go task -- some stimuli demand a response, others do not. As noted in lecture, think creatively about some comparison of two groups of stimuli you are interested in. It can be words, but anything representable in keyboard characters can be entered in the boxes below. (Obviously you are limited to 10 stimuli here, but that should be enough to do something basic, but interesting to you...)

After the experiment is run, a data set will be presented to you for entry into Microsoft Excel (preferable), or some other program. Open your data in Excel (or, if you like R or some other program, go ahead), calculate two averages (i.e., two conditions). Write one sentence that describes (very tentatively, obviously) what you've got so far. Just show your work by handing in your analysis.
