Chapter 12 endnote 9, from Lisa Feldman Barrett.
Some context is:
...caregivers also guide the infant’s attention to things of interest in the world. He follows their gaze to an object (say, a lamp), then they look at him, then at the lamp again, and talk about what he is looking at. They say the word “lamp” to him with intent, alerting and orienting him with a “baby talk” tone of voice. [...] The infant and her caregiver are sharing attention.
Shared attention and joint attention both involve two people (e.g., an infant and an adult) coordinating attention on an object or event in the world, plus an understanding that they are both interested in the same thing. These abilities develop rapidly, beginning around three months of age. This sort of social attention is more than just looking at the same object (shared gaze) — it is more like a conversation between two people, often without words, using gaze and sometimes pointing. There are many other ways to share attention as well, such as by touch.
Shared and joint attention are critical for developing concepts and regulating the infant’s body budget. As caregivers use words to name the things of interest, the infant brain more easily learns concepts that later become predictions. Connectivity between the amygdala and body-budgeting regions in the ventromedial prefrontal cortex (along the uncinate fasciculus, which is a bundle of axons) in six-month-old infants predicts the ability to engage in joint attention at nine-months of age. These dynamics not only contribute to the development of the default mode and control networks, but also to the sensory networks themselves. For example, expanding an infant’s affective niche with attentional cuing helps the visual system to develop.
