## Input
Keyboard-Single Keys

The “Keyboard-Single Keys” input device is for use when a single key (discrete) response is needed from participants. For USB keyboards, the timing resolution is generally about 10-14 milliseconds. On Windows, if using a PS2 keyboard, the timing resolution is about 16-36 milliseconds.

You can create as many responses as needed:

A response can consist of a key press or a key release. If you need a response that consists of a key release, make sure that the Ignore the key release checkbox is turned off. It is a good idea to give the response a descriptive name, e.g. “target” or “same”.

### Available Options

The following options are available for the “Keyboard-Single Response” input device:

- Ignore key release: If your experiment needs a response that consists of a key release, this option should be turned off. Otherwise it is a good idea to keep this option turned on.

- Wait until the key is released: When this option is turned on, SuperLab will not advance to the next event or the next trial (depending on which sub-option is selected) until the participant has released the keyboard key.

- Look for Single Key Responses From Participants: This option is generally useful when using more than one input device in the same experiment, and is particularly needed when that other input happens to be “Keyboard-String Input”. If you select the “For all events” setting, SuperLab will always look for a single key response from participants. This will cause a conflict if you also want the participant to be able to type words or sentences.
