اول از همه حرف شما که میگی من فقط این بخش رو خوندم قابل قبول نیست!!! میشه کار غیر دقیق و غیر علمی!!! بعد شما فکر کردی ویکی پیدیا از خودش حرف میزنه یا لینک رفرنس میده برای حرف هاش!! این امید شما هم در کل واهی هست چون شیوه بررسی علمی این شکلی نیست..شما خواستی تو بخث های فلسفی رفرنس علمی بدی که اشتباه کردی حالا دوست داری قبول نکن...الان برات رفرنس میذارم خوب دقت کن...نوشته اصلی از سوی مهربد
It has been claimed that the human corpus callosum shows sex differences, and in particular that the splenium (the posterior portion) is larger in women than in men. Data collected before 1910 from cadavers indicate that, on average, males have larger brains than females and that the average size of their corpus callosum is larger. A meta-analysis of 49 studies published since 1980 reveals no significant sex difference in the size or shape of the splenium of the corpus callosum, whether or not an appropriate adjustment is made for brain size using analysis of covariance or linear regression. It is argued that a simple ratio of corpus callosum size to whole brain size is not an appropriate way to analyse the data and can create a false impression of a sex difference in the corpus callosum. The recent studies, most of which used magnetic resonance imaging (MRI), confirm the earlier findings of larger average brain size and overall corpus callosum size for males. The widespread belief that women have a larger splenium than men and consequently think differently is untenable. Causes of and means to avoid such a false impression in future research are discussed. © 1997 Elsevier Science Ltd.Sex Differences in the Human Corpus Callosum: Myth or Reality?
ولی باز من میبینم ناقص نقل قول میکنی که مبادا به ضرر نتیجه گیریت بشه!!!
این لینک که فکر میکنی خیلی معتبر هم هست و دیگه امید داشتی بحث رو برای همیشه ببنده موضوعش اصلا در مورد multitasking هست نه تفاوت اندازه جسم پینه ای در زن و مرد!!! این نکته اول ...
بعد ببین کامل چی نوشته شده...بحث اصلی نوروساینس نیست اصلا و بحث روان شناسی هست..
Additionally, there is a biological difference. According to MRIs performed, women have a larger corpus callossum (Halpern, 2000). The corpus collossum is the area of the brain that handles communication between the two hemispheres. It is responsible for synthesizing the information from the left and right side of the brain. In women, the corpus callosum is wider than that of men’s brains, which might enable the two sides to communicate better with each other. This is a theory as to why women might multitask more efficiently.
There are people (e.g., Meyers, 2003) opposed to the idea of women being better multitaskers. However, they do not make a case for men being superior with multitasking abilities. Instead, they claim that there is no significant difference between the genders with multitasking. According to Dr. David Meyer (2003) the genders are fairly even in their multitasking abilities. He says that, “The two sexes typically come out about the same, on average” (Shellenbarger).
Dr. Marcel Just, Director of the Center for Cognitive Brain Imaging at Carnegie Mellon University agrees with Meyer. His studies on brain mapping, with participants between the ages of 18 and 32, show that women only score higher when asked to listen to two things at the same time (Just, 2001). In every other cognitive tasks pairing, there are no statistical differences. His conclusion is that men and women are equally productive with multitasking (Mahany, 2005).
My hypothesis is that women will score higher on the assessment of multitasking skills. This is based on the new evidence that is emerging about the corpus callosum
