Some of the labs in our department investigate cognitive development in young children. This is the film of Haven from a study. It is hard to tell what is going on because you see her, not the screen in front of her. After each beep, two pictures appear on the left and right. One is a flower the other is a snake. If Haven finds one more interesting than the other, she will look at it longer. The researchers are timing how long she looks at each. There is some evidence that snake fear is a "prepared fear" in that it might be much easier to acquire than other types of fears. The researchers are testing if interest in snakes appears early in development.
I don't know what happened because I had to have my eyes closed the whole time so as not to unintentionally influence Haven's looking behavior.
