Scientists tested 17 young people aged eight to 16 with autism. They gave them either oxytocin or a placebo through a nose spray. Then, the scientists scanned their brains while they looked at images of cars or the eyes of people expressing different emotions. The scans showed that some parts of the children’s brains behaved more normally after oxytocin: they were more active when the person was looking at faces and less active when the person was looking at the cars.
What were the two different groups in the experiment?
One group was given oxytocin; the other was given placebo One received oxytocin through injections; the other through a nose spray One group looked at images of cars; the other looked at images of facial expressions One group was given behavioral therapy; the other was given cognitive therapy
