CHESS AND THE BRAIN:

As our knowledge of the brain improves, so does our understanding of what chess can do for its development.

Below, is an article that may be extremely beneficial, as it provides insights from a neurological standpoint about how the brain works during chess play.

The benefits of chess are not all highlighted in this article, but, it should shed some light on a subject that still remains obscure to many.

Chess has long been recognized as a builder of strong intellects, it promotes logical thinking, self-confidence, improves communication and pattern recognition skills, and teaches the values of hard work, concentration, objectivity and commitment, to name a few.

Surprisingly, today there are still people in education that do not completely comprehend the role chess can play in the school curriculum.  It is my hope that this article can help on the road to understanding.

Chess Playing Helps Reveal How Brain Works
For release: Wednesday, May 18, 1994 / Date Last Modified: Tuesday, March 08, 2005

Tournament-level chess players are helping scientists at the National Institute of Neurological Disorders and Stroke (NINDS) identify parts of the brain used in complex problem solving. These studies have revealed a processing network that is distributed throughout the brain, according to Dr. Jordan Grafman and his coworkers. Grafman, who heads the Institute’s Cognitive Neuroscience Section, said that chess playing is an ideal model to help scientists better understand the coordinated work of the brain. The study will be published in the May 19 issue of Nature .*

“Imagine yourself as a chess player about to checkmate your opponent,” Grafman said in describing the work of the brain. “All your knowledge and experience are being retrieved for your next move. First, you perceive the pieces on the board and mentally separate the color-coded pieces. Then you analyze their positions on the board, identify the value of the different pieces, and retrieve the rules of the game for any move. If you are a skilled player like the 10 subjects in this study, you also recognize specific patterns that signify when you have an advantage over your opponent. Finally you have to analyze the consequences of your potential moves and the countermoves of your opponent.”

A brain imaging technique called positron emission tomography (PET) allowed Grafman and his coworkers to separate these steps and identify the parts of the brain used during each stage. A PET brain scan records the increased use of a radioactive tracer when a part of the brain is activated for a particular task.

For chess players, color separation and spatial discrimination activate parts on both sides of the brain toward the back of the head known to be associated with visual processing. Rule retrieval activates two parts on the left side of the brain, a small structure deep within the brain associated with indexing memories and a structure in an area near the left ear associated with memory storage. Checkmate judgment activates areas on both sides near the front of the brain crucial for planning and in the back of the brain important for generating images.

Grafman said experiments like the chess problem are helping improve our understanding of how humans make judgments. According to Grafman, the areas in the front of the brain activated in the checkmate judgment stage may be “managerial knowledge units.” These units are similar to other types of storage in the brain but coordinate a large amount of information in a specific sequence. Grafman said the findings in this study will ultimately be useful in helping people recovering from brain injuries or diseases that affect problem solving and judgment.

The NINDS is the nation’s principal supporter of research on the brain and nervous system and a lead agency for the Congressionally mandated Decade of the Brain. The Institute supports and conducts a broad program of basic and clinical neurological investigations. The NINDS is part of the National Institutes of Health, located in Bethesda, MD.

  1. I’d like to see a commercial that says: “This is your brain.” Followd by: “This is your brain on chess!”

    Hi Jim,

    This is your brain.” Followd by: “This is your brain on chess!” I agree. This was a better title for the blog.. But we can save it for future blogs..
