Early Years Toolbox (EYT) Mr. Ant is an iPad-based assessment of children's working memory (i.e., the amount of visual information that they can concurrently coordinate in mind). In this game, children encounter a cartoon character – Mr. Ant – who has placed a number of coloured stickers on different parts of his body. After a short time Mr. Ant disappears and, once he reappears without any stickers, the child is asked to recall the locations of the stickers by tapping where the stickers used to be. Trials are presented in order of difficulty, with a stop rule after a prescribed number of incorrect responses to prevent frustration associated with overly difficult items. This game takes approximately 5-8 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.

Gr8 find!

I downloaded Mr. Ant 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. I noticed some subtle strengths and weaknesses I hadn't spotted in the mayhem of the usual day.

In Mr. Ant, the student is presented with the Mr. Ant character with a spot of color placed on its body. The ant disappears, followed by a brief interval, reappears, and then the child is asked to tap the ant where the spot was previously located. Gradually, a second dot is placed on its body, then a third, etc. Nicely done!
