Go/no-go variant

Hello, we are trying to set up a version of go/no-go and we are running into a problem.

The version we are using has two response types, either a single tap of the space bar or a double tap of the space bar. Only one response is correct depending on the stimulus.

We have tried a “keyboard-single keys” strategy and a “keyboard-string input” strategy.

The problem with the “single keys” strategy is that two hits of the spacebar will register as two single taps (instead of a double tap). This is almost workable except it makes the data output file difficult to read since there is no easy way to see whether there was incorrect response.

The problem with the “string input” strategy is that response time is not recorded (we need it to be recorded from the initial tap for the double tap response).

I’m sorry if this is confusing, hopefully it makes sense. Any help would be greatly appreciated. Let me know if any specific clarification would help.

I can’t think of an easier way to do it than the one that you found.
