Clear-cut attachment phase and age range
Babies become solidly attached to their caregivers, and separation anxiety emerges. They also exhibit stranger anxiety in the presence of unfamiliar people. They can now crawl and walk, so they are able to actively seek proximity to chosen caregivers. They use caregivers as a secure base from which to explore their environment. 6-8 months to 18-24 months.

Three (important) principles of attachment
Alarm of some kind stemming from an internal source (such as pain) or an external source (such as a loss of contact with a caregiver), activates the "attachment behavioral system"; once the system is activated the infant is motivated to seek out soothing physical contact with the "attachment figure"; if the infant's attempt succeeds the system deactivates, infant is soothed, and play exploration can resume big if no attachment figure is found the infant experiences extreme arousal and anxiety

Humans have a specialized for understanding emotional states. The development of information processing capacities (cognitive flexibility, working memory, etc.) helps children with logical reasoning.
4 Rules babies look like (Haith)
If awake and light isn't too bright open eyes. Search for contrasting edges. If you find edges, star near them and cross back and forth over them, as the clustering of edges increases, scan the edges more and more narrowly. Following these rules → maximal stimulation of visual cortex.
A-not-B task
In the A-not-B task, a researcher hides a toy in one position (position A), and the baby retrieves it. After several repetitions, the researcher takes the toy from the baby and places it in a different position (position B) as the baby watches. But the baby once again searches for the toy in position A. This behavior is taken as evidence that the baby cannot predict what happens to an object when it disappears.

Preattachment phase and age range
Infants' behaviors, such as crying, sucking, rooting, and eye-gaze, are beautifully designed to promote proximity and contact with a protective, caregiving adult. However, babies are not yet attached to
