## What is EYT Go/NoGo?

Early Years Toolbox (EYT) Go/No-Go is an  iPad-based assessment of children's inhibition (i.e., ability to control behavioural impulses). In this game, fish and sharks swim across the screen and children are instructed to tap the screen whenever they see a Fish (‘catch the fish’) and refrain from tapping when a Shark appears (‘avoid the sharks’). This game takes approximately 5 minutes to complete.

Scores are presented on the final assessment screen. For more precise research applications, there are options to have the item by item data sent to a user-specified e-mail address or database. For more information, training videos and analysis resources, please visit http://www.eytoolbox.com.au

About the Early Years Toolbox:

The 'Early Years Toolbox' (EYT, for short) is comprised of brief, engaging game-like assessments of  children’s self-regulation, executive functioning and vocabulary. These assessments are based on well-established and widely used measures, yet have been adapted and optimised on the basis of 20+ years of research experience working with young children.

### 5/5 — Another nice app from EYT

*2014-11-24*

I downloaded Go/NoGo and other apps from this developer, and each one was friendly but low-key and progressed at a reasonable pace. Data is available, and it was interesting to observe the children attempting the activities. In Go/NoGo, the child is asked to tap the screen when a clown fish swims past -- but the child is not to tap when a shark swims by. This required considerable impulse control from the children!
