Listen to part of a lecture in a psychology class.

Okay. Let's begin with a quick review. We've covered different aspects of preverbal development in infants, like when they're making random emotions and sounds or recognizing voices or or beginning to discriminate between different sounds. But with everything we've talked about so far, the babies mostly reacting to what its caregiver does. And aside from expressing expressing basic needs, baby really isn't initiating communication.

So today we'll see how babies start to become active partners with their caregivers. For the first 7 or 8 months, the baby responds to stimuli, but we don't see intentional attempts to communicate. What I mean is part from their immediate needs. Babies don't communicate anything about the world around them. Then typically, at about 9 months old, the baby enters a new an important stage in normal, communicative development, and will begin to engage with others as an active participant. And this is essential for real intentional communication. To understand what's going on here. Let's look at something called joint attention. So the ability to share a focus of attention with someone else that's joint attention. Two or more people have a connected awareness of the same thing. And in just a few minutes, we'll watch a video about babies beginning to use this vital skill. We'll see how using joint attention begins to lead towards intentional communication. But where does an infant learn this skill? Well, from its adult caregiver, the infant begins to follow the gaze of the adult, try to see what the adult is focusing attention on and to share with the adult, the experience of looking at this object.托福TPO73听力Lecture1原文余下省略！
