中国人获“搞笑诺贝尔奖”

   据美联社报道，2014年“搞笑诺贝尔奖”颁奖典礼当地时间19日在哈佛大学举行。获奖名单中，我们看到了中国人的身影。类别属于神经学奖，研究课题为“当人们在烤面包里看到耶稣基督的脸的时候，大脑内会有何种反应”。这是2010年广东昆虫研究所张礼标获得生物学奖后，华人科学家再次“斩获”此奖项。

究竟是什么机制让人们在一些平常的物品中看到人脸的形状？这并非发疯，而是有着科学的名称，那就是所谓“人脸空想性错视”(Face pareidolia)。这种现象让人们在月球上看到了人的身影，在火星上看到了神秘的人脸，在一片土豆片上看到猫王。但这种现象的原因则仍然未知。

加拿大多伦多大学的李康教授和他的中国同事们因为在此方面的研究工作而赢得了2014年度搞笑诺贝尔神经科学奖。他们向一组志愿者展示一系列完全随机的图像，但告诉他们这其中有一半的图像中隐藏有人脸图形。这样的结果是这些志愿者认为向他们展示的图像中有37%的确含有人脸。随后进行的大脑扫描显示他们大脑中的梭状回面孔区(FFA)区域出现了活动，这是负责面部识别的大脑区域。研究组随后以《在烤面包中看到耶稣基督：人脸空想性错视的神经与行为学研究》为题发表了研究论文。

论文摘要：Face pareidolia is the illusory perception of non-existent faces. The present study, for the first time, contrasted behavioral and neural responses of face pareidolia with those of letter pareidolia to explore face-specific behavioral and neural responses during illusory face processing. Participants were shown pure-noise images but were led to believe that 50% of them contained either faces or letters; they reported seeing faces or letters illusorily 34% and 38% of the time, respectively. The right fusiform face area (rFFA) showed a specific response when participants “saw” faces as opposed to letters in the pure-noise images. Behavioral responses during face pareidolia produced a classification image (CI) that resembled a face, whereas those during letter pareidolia produced a CI that was letter-like. Further, the extent to which such behavioral CIs resembled faces was directly related to the level of face-specific activations in the rFFA. This finding suggests that the rFFA plays a specific role not only in processing of real faces but also in illusory face perception, perhaps serving to facilitate the interaction between bottom-up information from the primary visual cortex and top-down signals from the prefrontal cortex (PFC). Whole brain analyses revealed a network specialized in face pareidolia, including both the frontal and occipitotemporal regions. Our findings suggest that human face processing has a strong top-down component whereby sensory input with even the slightest suggestion of a face can result in the interpretation of a face.
