پژوهش جدیدی چنین القا می کند که اسکن های مغزی می تواند فرد را به سوی بهترین شغل برایش راهنمایی کند. نتایج این پژوهش همچنین نشان می دهد که نقاط قوت و ضعف شناختی هر فرد به تفاوت هایی در حجم ماده خاکستری در قسمت هایی از مغز ارتباط دارد.
ریچارد هایر از دانشکده پزشکی دانشگاه کالیفرنیا در اروین به لایوساینس گفت که در حال حاضر یافته ها "این امکان را بیان می کند که اسکن های مغزی در آینده ممکن است برای ایجاد نمودار خصوصیات/پروفایلی از ماده خاکستری در مناطق گوناگون مغز یک فرد استفاده شود، و این نمودار خصوصیات می تواند همانند نتایج آزمون های [موجود کنونی] برای کمک به افراد در تصمیم گیری آنها برای انتحاب نوع شغلی که آنها ممکن است در آن کارآمد باشند به کار گرفته شود."
هایر و همکارانش داده ها از 40 نفر بین سنین 35 تا 18 را که آزمون های استعدادیابی بنیاد پژوهشی جانسون اوکانر برای راهنمایی حرفه [یابی] را تحلیل کردند. آنها همچنین اسکن های ساختاری از مغز [آنها] را در اختیار داشتند که حجم ماده خاکستری را در میلیون ها واحد های سه بعدی که وکسل نامیده می شود در این تصاویر مغزی نشان می داد.
این آزمون ها برای دو نوع از حافظه (گفتاری و شمارشی)، دو گونه از قابلیت های شمارشی، سرعت استدلال، و دو گونه استعداد فضایی را شامل می شد.
نتیجه آزمون ها نشان داد که اگر کسی [فقط] به آزمون گونه های حافظه نگاه می کرد بخشی از تصویر کلی را از دست می داد. برای نمونه، اگر کسی در حافظه گفتاری خوب بود و در شمارشی چندان خوب نبود، الگوهای ماده خاکستری او از کسی که درمجموع حافظه نتایج خوبی به دست آورد اما نتیجه پایینی در گونه گفتاری داشت فرق می کرد. ...
Brain Scans Could Guide Career Choices

Brain scans may guide a person toward the optimal career, new research suggests.
The results show people's cognitive strengths and weaknesses are linked to differences in the volume of gray matter in certain parts of the brain.
As such the findings offer "the possibility that brain scans could be used in the future to develop a profile of a person's gray matter in different areas of the brain," Richard Haier of the University of California, School of Medicine (Emeritus), Irvine, told LiveScience. "And this profile could be used to help people decide what kinds of vocations they might be good at just like test scores are used."
Brain voxels
Haier and his colleagues analyzed data from 40 people, ages 18 to 35, who took eight aptitude tests used by the Johnson O'Connor Research Foundation (JOCRF) for career guidance. They also had structural brain scans, which showed the volume of gray matter for each of millions of 3-dimensional units, called voxels, in the brain images.
The tests included those for two kinds of memory (verbal and number), two types of numerical ability, speed of reasoning, and two types of spatial aptitude.
Results showed if one were to look at a general memory test score you'd be missing part of the picture. If a person was good at, say, verbal memory and not so much in numerical, their patterns of gray matter would differ from someone with high overall memory but low verbal type.
Future career counselors?
Brain scans could be used to complement the aptitude tests to give a more reliable idea of a person's ideal career.
"Nobody is suggesting brain scans would predict this so well you wouldn't need to talk to anybody, although this is a science-fiction possibility - but whether society would accept this is dubious," Haier said.
The link between brains and jobs makes sense, in the Earthly realm. "It's not a giant leap to believe the brain has something to do with mental strengths and weaknesses," which have to do with a person's vocation.
For instance, while most of us can learn to drive, not everyone can become a professional racecar driver. Whether it's relatively slow reaction time or a weakness in the spatial reasoning department, there are some special kinds of cognition involved in driving at extremely high speeds, Haier said.
"Theoretically there might be something about their brains that allows them to excel in this profession," Haier said.
