What was the finding of the study published in Psychological Science in 2008?
Babies took more interest in snakes than the other animals in the videos regardless of which human voices they heard.
The longer babies looked at snakes in the video, the less scared they were.
The fearful voices babies heard when watching snake videos doubled their fear of snakes.
Babies' responses to the snake in the videos were greatly affected by the types of voices they heard.
