All You Can ET is a game designed to train cognitive flexibility, a subskill of executive functions. Cognitive flexibility involves inhibiting a prior perspective and considering a new perspective (Diamond, 2013). Players need to apply frequently changing rules to give differently colored aliens the right food or drink they need to survive. How does this support learning? Executive functions refer to a set of top-down, goal-oriented cognitive processes that enable people to control, monitor and plan behaviors and emotions. Miyake and Friedman’s model supports a unity-and-diversity view of EF in that it incorporates the three distinct but related components of EF: inhibitory control, task-switching and updating (Miyake et al., 2000). What is the research evidence? Our research suggests that All you Can ET is an effective way to train Cognitive flexibility.

Activating Adolescents’ “Hot” Executive Functions in a Digital Game to Train Cognitive Skills: The Effects of Age and Prior Abilities. Cognitive Development, 49, 20-32. Research has found that EF is related to performance in literacy and math along with long-term gains in school performance and academic readiness (Blair & Razza, 2007; Brock, Rimm-Kaufman, Nathanson, & Grimm, 2009; St Clair-Thompson & Gathercole, 2006; Welsh, Nix, Blair, Bierman, & Nelson, 2010) and that disparities in EF among preschool children from low-income versus high-income homes may contribute to the achievement gap (Blair & Razza, 2007; Noble, McCandliss, & Farah, 2007). This game is part of the Smart Suite, created by New York University’s CREATE lab in collaboration with the University of California, Santa Barbara, and The Graduate Center, CUNY. The research reported here was supported by the Institute of Education Sciences, U.S. Department of Education, through Grant R305A150417 to the University of California, Santa Barbara.

So far I’m finding this app legitimately challenging but just enough so it doesn’t make me wanna give up, it genuinely feels like a brain exercise, especially when I reached the second page of levels. I’ve become super interested in Central Executive Training (CET) and I’ve been searching for ways to implement this training into my day-to-day, but most of what I find is research articles and just a couple of games such as this one. Before I continue playing I was wondering if there was a way to reach out to the development/research team to give feedback, and to also ask questions, such as - is it better to play this game with or without my medication? Thanks for taking the time to read my review, and thank you for all that you do :) ### 5/5 — Thought drift sinks you *2022-12-29* I am enjoying this game. It is a fun little diversion. What I find interesting about it is, if I focus I get easily get 100% of the targets. But as soon as my thoughts drift, I start missing almost all of them. If you want a high score, play when you can give this game total attention. ### 3/5 — Level Select Screen is Glitched *2020-08-13* Hello, I’m writing this to inform the developers that the level select screen is bugged. It does not allow me to choose levels I have already completed, with locks still over the icons despite three golden stars being under the lock. I accidentally reset to level 1, and would not like to restart all the way to where I was before. ## Frequently asked questions about All You Can ET ### What is All You Can ET?
