In neuropsychology the left brain interpreter refers to the construction of explanations by the left brain in order to make sense of the world by reconciling new information with what was known before.〔''Neurosociology: The Nexus Between Neuroscience and Social Psychology'' by David D. Franks 2010 ISBN 1-4419-5530-5 page 34〕 The left brain interpreter attempts to rationalize, reason and generalize new information it receives in order to relate the past to the present.〔''The Seven Sins of Memory: How the Mind Forgets and Remembers'' by Daniel L. Schacter 2002 ISBN 0-618-21919-6 page 159 ()〕 Left brain interpretation is a case of the lateralization of brain function that applies to "explanation generation" rather than other lateralized activities.〔''The cognitive neuroscience of mind: a tribute to Michael S. Gazzaniga'' edited by Patricia A. Reuter-Lorenz, Kathleen Baynes, George R. Mangun, and Elizabeth A. Phelps; The MIT Press; 2010; ISBN 0-262-01401-7; pages 34-35〕 Although the concept of the left brain interpreter was initially based on experiments on patients with split-brains, it has since been shown to apply to the everyday behavior of people at large.〔 ==The discovery== The concept was first introduced by Michael Gazzaniga while he performed research on split-brain patients during the early 1970s with Roger Sperry at the California Institute of Technology.〔〔''Handbook of the Sociology of Emotions'' by Jan E. Stets, Jonathan H. Turner 2007 ISBN 0-387-73991-2 page 44〕〔''Handbook of Neuropsychology: Introduction (Section 1) and Attention'' by François Boller, Jordan Grafman 2000 ISBN 0-444-50367-6 pages 113-114〕 Sperry eventually received the 1981 Nobel Prize in Medicine for his contributions to split-brain research.〔Trevarthen, C. (1994). "Roger W. Sperry (1913–1994)". Trends in Neurosciences 17 (10): 402–404.〕 In performing the initial experiments, Gazzaniga and his colleagues observed what happened when the left and right hemispheres in the split brains of patients were unable to communicate with each other. In these experiments when patients were shown an image within the right visual field (which maps to the left brain hemisphere), an explanation of what was seen could be provided. However, when the image was only presented to the left visual field (which maps to the right brain hemisphere) the patients stated that they didn’t see anything.〔〔''Understanding psychology'' by Charles G. Morris and Albert A. Maisto 2009 ISBN 0-205-76906-3 pages 56-58〕〔Michael Gazzaniga, ''The split brain revisited''. Scientific American 297 (1998), pp. 51–55. 37 ()〕 However, when asked to point to objects similar to the image, the patients succeeded. Gazzaniga interpreted this by postulating that although the right brain could see the image it could not generate a verbal response to describe it.〔〔〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「left brain interpreter」の詳細全文を読む スポンサード リンク
