Early Years Toolbox (EYT) Not This is an iPad-based assessment of children's working memory (i.e., the amount of auditory information that concurrently can be coordinated in mind). In this game, children are presented with an array of characters (i.e. shapes that have cartoon expressions on their faces) that vary in shape, size and colour (e.g., a large blue circle). Before the characters are shown, children hear an auditory instruction to point to a card that does not fulfill a certain descriptive quality (e.g. “Find a shape that is not red” or “Find a shape that is not a triangle and is not large”). For each level, the number of descriptive qualities that must be held in mind increases. Trials are presented in order of difficulty, with a stop rule after a series of incorrect responses to prevent frustration associated with overly difficult items. This game takes around 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.

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.

I downloaded Not This, Mr. Ant, and other apps from this developer, and each one was friendly but low-key and progressed at a reasonable pace. This one has the child choose a shape that does not have the characteristic that is named, such as, "Can you find the one that is not red?" There are numerous choices, and the questions gradually increase in complexity. "Can you find one that is not green and not a square?" etc.

Need more error feedback

This would be great for working memory. But if the student makes an ERROR he needs to know it immediately. There's no obvious way to know. Can't improve without feedback. (FYI, speech therapists and teachers love data collection, if you are ever able to pay for that feature.)

If you are able to have the app signal about errors this will be a great app!
