# Feedback, responses and validations

Feedback means the correct or incorrect response displayed when a participant presses a key on their keyboard or clicks a mouse button. When the participant presses a key, the element will move onto the next one, regardless of the element's duration. <br>

Response options include:

* Any keypress means that the experiment will move onto the next element when the participant presses any key on their keyboard.&#x20;
* Nominated keypress means the experiment will move onto the next element when the participant presses the specified key(s) on their keyboard.&#x20;

Feedback options include:

* Sound and visual feedback for correct responses. When a participant selects a correct answer, a green tick is shown and/or a 'correct' sound will play. &#x20;
* Sound and visual feedback for incorrect responses. When a participant selects an incorrect answer, a red cross is shown and/or an 'error' sound will play.&#x20;

Key validations include:

* Define whether a subject's response is given a tick or cross.&#x20;
* Can be set for an element tag, name, text, or color.&#x20;

The name used for a validation must use the file name for that element. Do not give the validation a different name. \
