[原创]顺时针？逆时针？左右脑测试？OR  视觉欺骗！

蓝白黑

网上流传甚广的测试：

你看到那位舞蹈者是朝哪个方向旋转呢？我们大多数人都会看到是“逆时针”旋转，你可以试试看是否能让她改变方向。


这是一个在网上广为流传的关于“左脑型”和“右脑型”的心理测试游戏，由于传播中的信息损失和变异，有人把它当作了智商测试。这个问题曾在网络上引起了热烈讨论，有些人说看到舞蹈者反复变转方向，有些人就是看不出来，难道仅仅凭一张旋转的舞蹈图，就能测出人类的智商吗？Psytopic认为这个测试和智商无关，但不能确定是否和“思维类型”有关。
答案分析：
看到不同的旋转方向，代表着不同的思维类型，如果看到舞蹈者逆时针旋转的时候更多，代表您是“左脑型”占优势；如果看到舞蹈者顺时针旋转的时候更多，代表您是“右脑型”占优势。很少人会是纯粹的“左脑人”或“右脑人”，基本上您都能看到两种方向的旋转，只是他们的时间比例各有差异。
左脑型 VS 右脑型
德国科学家赫尔曼.哈肯（Hermann Haken）在《大脑工作原理》一书中指出：“在对大脑的研究过程中发现，特定的功能可能源于大脑的某一区域。大脑的损伤和撞击是判明这种功能区域的第一个指示器。例如，撞击大脑的左半球会引起身体右侧瘫痪，比如右腿、右手臂和右手的瘫痪。与此类似，撞击大脑的右半球会引起身体左侧部位的瘫痪。”这是左右脑思维模型划分的一些生理依据。

我只找到这么早的东西了，但是我记得我第一次看到这个图要比这个早，懒得找了……

这个图还很有趣很强大的，以前看这种东西看得比较多，所以看到后第一反应就是视觉欺骗。

此图总共有34帧，随便哪一帧在视觉上都是有歧义的——有兴趣的可以截图看看。

近日心血来潮，想查查他的源头，百了国内的网站，基本上一个调调，还有说耶鲁大学耗时5年的研究成果……不知道哪个中国牛人想出来的……很油菜……
于是耐着性子去看了下英文……累ing……权当练习阅读了

So what does the spinning dancer tell us? The whole test is more of an optical illusion（视错觉） than anything else, according to Steven Novella, an academic clinical neurologist at Yale University School of Medicine who blogs on NeuroLogica（持反驳意见的就是耶鲁大学相关学科的专家）. When our brains process visual images to make some order or sense of the world, they have to make assumptions.
The dancer is just a two dimensional image switching back and forth, but our brains process it as a three dimensional spinning object. 图片只是二维的，而我们的大脑把它作为三维物体来处理！
Depending on the assumptions made and visual cues picked up, your brain can make the dancer spin either way. When my friend first sent the test to me, I saw it go clockwise…then switch to counterclockwise as I was staring at the screen. What this tells me about my personality and mental abilities is hardly a no-brainer – the brain test connection to our mental strengths and weaknesses is nonexistent.
一开始是某个方向，然后一转身，反了，哈哈，也有怎么都变不了，可能是思维定势比较强吧。

What can you see? Clockwise rotation? Anti-clockwise rotation? Both?
This is an interesting test posted on the Daily Telegraph website, and it is purported to test whether you are a left-brained or right-brained person. But from my one semester of neuroscience,（这位是学神经系统科学的）， I would say that the left-brain / right-brain dichotomy thing is mostly bullshit. While there are indeed dominant spheres for language processing (most people are left-sided, some people are right-sided, even less are both-sided) as well as spatial perception (which is usually on the right side);
the left-side = rational, right-side = emotional / linguistic / artistic theory is a hypothesis and has not been substantiated scientifically.
左右脑分工都只是一个猜想而已……大多数认同的情况是左右脑都具有上述功能！
It is often exaggerated in popular psychology and often is used to sell \"boost your left brain\" or \"train to use both your brains\" kind of pseudoscience stuff.（伪科学），卖脑健品的＆开发大脑潜能*#￥%@ 做广告时常用的夸张手法

One of the current external links on the site:
Left Brain/Right Brain Visual Aptitude Test
links to an adult site. From my brief check, the site only has this one page on lateralization as it pertains to this article. While it's an interesting graphic, and it has something to do with left and right as concepts, I don't see any reason for its inclusion in this article.  Its claim to be a diagnostic tool for determining left/right dominance (\"If [you see the image turning] clockwise, then you use more of the right side of the brain and vice versa.\"), is unsupported AFAIK. I will remove it if there are no objections. Aaron.michels (talk) 19:00, 16 April 2008 (UTC)
This is a pretty clear case of an inappropriate external link. Feel free to remove this and any other clear violations. --Gimme danger (talk) 23:31, 16 April 2008 (UTC)
