於是就去睇一大堆嘢，好很攰，but seems promising!呢個list應該會繼續expand落去~
Types of Attention
Sustained attention is the ability to focus on one specific task for a continuous amount of time without being distracted.
Selective attention is the ability to select from many factors or stimuli and to focus on only the one that you want while filtering out other distractions.
Alternating attention is the ability to switch your focus back and forth between tasks that require different cognitive demands.
Divided attention is the ability to process two or more responses or react to two or more different demands simultaneously. Divided attention is often referred to as multi-tasking.
關於 brain / cognitive training 嘅研究時間好短，甚至比還元水仲短。PowerbrainRX套方法係由美國LearningRX為亞洲人，尤其香港學童修改而嚟（因為要寫中文字，難過英文字母好多咁話，背後理據如何，邊個改，點樣改唔知，反正你又搵唔到原本嚟對比架喇。）

LearningRX Insider Secrets: How to Negotiate a Better Price from LearningRX
According to one LearningRX insider (who’s contributing under the name Former LRX), despite the company’s claims that its programs benefit nearly every student, the LearningRX program “helps some a lot, some a little, and some not at all…”
“LRX gets good results for those students who work hard and stay focused on training, who have fun through the process,” writes Former LRX.
“Signing up is the right answer as long as you do so with your eyes wide open. That’s why I am here, because I don’t think most parents have their eyes wide open.”
A Consensus on the Brain Training Industry from the Scientific Community
針對美國o既brain training industry，實有業者吹到天花龍鳯，所以有堆科學家出嚟插話呢啲嘢冇用架。

The OPEN LETTER
Media Guide on LearningRx Settlement with the Federal Trade Commission
重點：FTC曾經告過一堆BRAIN TRAINING SERVICE PROVIDER，而LearningRX搵返位去反駁，講成件事點settle，照計間嘢目前仍然未執笠，即係有理由相係可能work嘅。
D. Expert Validation of LearningRx’s Substantiation
LearningRx’s substantiation has been reviewed by Dr. Howard Wainer, Distinguished Research Scientist with the National Board of Medical Examiners, retired Professor of Statistics at the Wharton School of the University of Pennsylvania, former Principal Research Scientist with the Educational Testing Service, and author of numerous articles and books on statistics. See Dr. Wainer’s analysis and findings, along with his curriculum vitae. He concludes that:
(1) Research other than RCTs, including powerful observational studies, can and commonly do provide “evidence to estimate causal effect”;
(2) LearningRx’s observational and randomized controlled studies “all support the credibility of the claims made that those trained using the LearningRx approach markedly increased scores on IQ tests and, more particularly, on sub-scores of those tests”;
(3) Randomization was not feasible for the small subgroups, such as TBI, autism, and dyslexia, but “with effects as consistently large as was being observed, the decision to go forward, as was done, was both ethically and scientifically preferable. Within the constraints that exist, therefore, there is convincing evidence supporting the claims of efficacy made.”
In sum, LearningRx’s efficacy claims are well-supported by the pre-post data from the many thousands of students who have completed the program, RCTs, the expert opinion of an eminent statistician, and the scientific literature with regard to the claims of correlation between cognitive ability and academic, financial, and athletic achievement.
佢哋自己做嘅更多independent support (冇人知係咪真係independent)
但brain training只有幾十年，其實佢哋啲研究結果已經比還元水吸引少少，雞髀6歲，等debate到佢7、8十歲？大量testimonial話work，但即使2015年亦繼續有研究話冇乜明顯效果，但依然改善咗working memory:

6 Brain Training Exercises for Children and Teens
3. The Concentration Game. Activities to improve memory and concentration are important for all of us! For younger children, you can take a few of their toys and line them up. Then cover them and take one away. See if they can tell you which one is missing. You can also have them try to remember short lists of familiar objects in the home. Try remembering them forward and backward. For older children and teens, try putting random objects in front of them for 15 seconds, then remove the objects and see how many they can remember. Start out with five and keep increasing the number as they master the task. You can also help auditory memory by giving them a random list of numbers or words orally and having them repeat them. Start with only 2 or 3 and work up from there.
對雞髀咁差嘅visual short-term memory好似幾有用，可以試吓。
