Cognitive Ability: Brain Games or Drugs?
A recent scientific study is being welcomed as a landmark that shows how fluid intelligence can be improved through training. I interviewed one of the researchers recently (Can Intelligence Be Trained? Martin Buschkuehl shows how), and contributor Dr. Pascale Michelon adds her own take with the great article that follows. Enjoy!

What is intelligence?
Intelligence is a concept difficult to define as it seems to cover many different types of abilities.
One definition dissociates between crystallized intelligence or abilities and fluid intelligence. Crystallized intelligence refers to the knowledge acquired throughout life such as vocabulary. Fluid intelligence is the ability that allows us to adapt to new situations or problems.

Thanks to new neuroimaging techniques, regarded “as important for neuroscience as telescopes were for astronomy”, neuroscientists and cognitive psychologists have been finding that the brain has a number of "core capacities" and "mental muscles" that can be exercised through novelty, variety and practice, and that exercising our brain can influence the generation of new neurons and their connections. Brain exercise is being recognized, therefore, as a critical pillar of brain health, together with nutrition, physical exercise and stress management.

"Today, thanks to fMRI and other neuroimaging techniques, we are starting to understand the impact our actions can have on specific parts of the brain."- Dr. Judith S. Beck, Director of the Beck Institute for Cognitive Therapy and Research, and author of The Beck Diet Solution: Train Your Brain to Think Like a Thin Person. 
“Learning is physical. Learning means the modification, growth, and pruning of our neurons, connections–called synapses– and neuronal networks, through experience...When we do so, we are cultivating our own neuronal networks. We become our own gardeners”- Dr. James Zull, Professor of Biology and Biochemistry at Case Western University. 
“Exercising our brains systematically is as important as exercising our bodies. In my experience, “Use it or lose it” should really be “Use it and get more of it”.- Dr. Elkhonon Goldberg, neuropsychologist, clinical professor of neurology at New York University School of Medicine, and disciple of the great neuropsychologist Alexander Luria. 
“What research has shown is that cognition, or what we call thinking and performance, is really a set of skills that we can train systematically. And that computer-based cognitive trainers or “cognitive simulations” are the most effective and efficient way to do so.” - Dr. Daniel Gopher, Director of the Research Center for Work Safety and Human Engineering at Technion Institute of Science. 
“Individuals who lead mentally stimulating lives, through education, occupation and leisure activities, have reduced risk of developing Alzheimer’s symptoms. Studies suggest that they have 35-40% less risk of manifesting the disease”- Dr. Yaakov Stern, Division Leader of the Cognitive Neuroscience Division of the Sergievsky Center at the College of Physicians and Surgeons of Columbia University, New York. 
"It is hardly deniable that brains enchant Japanese people. We love brain training. Dentsu, the biggest advertising agency, announced the No.1 Consumer-chosen 2006 Product was game software and books for brain training."- Go Hirano, Japanese executive, founder of NeuWell. 
“Elite performers are distinguished by the structuring of their learning process… It is important to understand the role of emotions: they are not “bad”. They are very useful signals. It is important to become aware of them to avoid being engulfed by them, and learn how to manage them.” - Dr. Brett Steenbarger, Associate Professor of Psychiatry and Behavioral Sciences, SUNY Medical University, and author of Enhancing Trader Performance. 
“We have shown that working memory can be improved by training...I think that we are seeing the beginning of a new era of computerized training for a wide range of applications” – Dr. Torkel Klingberg, Director of the Developmental Cognitive Neuroscience Lab at Karolinska Institute. 
“Training is very important: attentional control is one of the last cognitive abilities to develop in normal brain development...I can easily see the relevance in 2 fields. One, professional sports. Two, military training.” Professor Bradley Gibson is the Director of the Perception and Attention Lab at University of Notre Dame. 
“I don't see that schools are applying the best knowledge of how minds work. Schools should be the best place for applied neuroscience, taking the latest advances in cognitive research and applying it to the job of educating minds.” - Dr. Arthur Lavin, Associate Clinical Professor of Pediatrics at Case Western School of Medicine, pediatrician in private practice. 
“Cognitive training rests on solid premises, and some programs already have very promising research results. Some of the most are promising areas are: neurofeedback, which as a whole is starting to present good research results, and working memory training.” - Professor David Rabiner, Senior Research Scientist and the Director of Psychology and Neuroscience Undergraduate Studies at Duke University:
