Am running an experiment with a series of trials, where in each trial I present participants with text describing hypothetical scenarios and ask them to create a written response in a text box at the end of trial.
So each trial is made up of 3 events: (1) scenario is presented, after reading it participant presses spacebar to progress to (2) a question prompts them to provide a response, and (3) would be the written response the participant provides, before pressing return key to end trial.
Problem is, the RT I really want to measure is the time between when (2) the question asked of them appears on screen, and when they strike the first key in their written response.
How can I ensure that the moment when they strike the first letter in their written response serves both as the mechanism that ends event (2)/begins event (3) but also ensure that this character they strike appears in the text box rather than just acting as a trigger for the text box to appear?
Or otherwise how can I ensure that the timer is reset upon the participant striking the first key of their response with the character being preserved as part of the written response.
