Recursion: The Concept Recursion is used in a variety of disciplines ranging from math, to computer science to linguistics. Recursion is one of the central ideas of computer science – where a function can call itself from within its own code, allowing for very powerful computation. Recursion in computer science – as in the recursive n-back – is a method of solving a problem where the solution depends on solutions to smaller instances of the same problem. What is recursion? Recursion occurs
Intelligence & IQ Defined A good cognitive science definition of general intelligence is: “. . . that facet of mind underlying our capacity to think, to solve novel problems, to reason and to have knowledge of the world.” M. Anderson This op-ed statement signed by fifty-two researchers in the field (ref) extends this idea to include learning and being ‘switched on’: “A very general mental capability that, among other things, involves the ability to reason, plan, solve problems, think
When you train with i3 Mindware software, ensure that you maximize the ‘core dual n-back training’ effect by adopting the following principles. Minimize going into ‘automatic pilot’ in the game. Ensure you are always putting in effort and the task is always challenging and absorbing. Ensure that you work at successfully ignoring distracting information – focusing on only what is needed for target ‘matches’. When interference is high, focus and keep your accuracy levels high. In the continuous stream of information, ensure that
Can brain training increase intelligence? This question has sparked off an animated debate going on among scientists, journalists, and social media pundits. I’ve been involved in an extended Quora debate on this topic myself recently. Who hasn’t been involved in this debate? I want to take the opportunity to clarify some key definitions that help us evaluate the claims, and then take a closer look at the evidence. This article is targeted at an audience who want to invest some effort into understanding
Summary A study published this month in the prestigious journal Intelligence has shown: Cognitive training combined with exercise results in gains in fluid intelligence (visuospatial reasoning) – a key measure of IQ. Fitness only training did not bolster fluid intelligence performance. Individuals varied in benefits to fluid intelligence from mindfulness training. The research team concluded: “Because fluid intelligence test scores predict real-world outcomes across the lifespan, boosting intelligence ability via multi-modal intervention that is effective even in young, healthy adults is a
There are 3 elements to i3 brain training: (1) Attention focus and chunking training; (2) Working memory training; (3) Executive function training. In this article we’re looking at the first of these. . Attention Focus & Chunking: Expert Perception Experts in any field differ from novices in their perception. More generally, smarter people have a better ability to quickly learn how to perceive a situation. Perception is an active process: we select and organise the data that bombards our senses using our

Here we’ll be reviewing Lumosity’s one and only comprehensive scientific study into the effectiveness of its brain training programs for the general population. The study was published last month in PLoS One (full paper here). The Lumosity study The study can’t be faulted for the number of participants in the study – what is referred to technically as its statistical power. There were 4,715 participants, covering all age groups. Participants were divided into a brain training group and a control group. The brain training
