communication between certain areas of the brain. After conducting various experiments, scientists revealed that unlike normal people, autistics have a very low brain activity when they are involved in social situations. A recent experiment has proved the theory that autistic peoples poor social interaction skills are generated by weak connections between brain areas. The experiment brought together 16 people diagnosed with autism and 16 people who didnt suffer from the disorder. Scientists measured the brain activity levels and responsiveness of both normal and autistic people when they were shown a sequence of images. The subjects were asked to identify certain differences between a series of images that represented objects and human faces. Normal people revealed higher levels of brain activity when they were shown the images that represented human faces and lower levels of brain activity when they were shown representations of objects. By contrast, all autistic people who participated to the experiment revealed low levels of brain activity regardless of what the images represented. The results of the experiment can be interpreted in many different ways. For many people, the experiment might suggest that there are abnormalities in some areas of the brain that prevent autistics from processing human features. However, medical scientists explain that autistic peoples actual problem is their inability to focus properly on human features rather than their inabil 上一页 [1] [2] [3] 下一页 |
