At 3 months Jack is able to focus his eyes on me and spends a lot of time studying my face and other faces of anyone around him. This increase in visual skills is because of a growth spurt with Jack's synapses and myelinization in his brain. (pg. 116 & 201) -

Jacks height has grown to 25 inches long and his weight has doubled to a whopping 15 pounds! (pg. 114) -

Jack's multimodal approach to perception leads his curiosity. He will place almost any object in his mouth to learn about it with his senses. How an object looks, sounds, feels, and tastes are combined to produce his reaction to the object. (pg. 136) -
8 Months
At 8 months Jack demonstrated object permanence by playing a game where he finds a hidden object. If I were to hide the object in the same place more than once and then relocate it to a new hiding spot, Jack showed a tendency to look in the old hiding place and feel confused when he didn't find the object there or he would forget about the object.
Object permanence is important because it shows that Jack can think about an object and know it exists without him knowing it's available. (pg. 145) -

At 12 months old Jack tries the object permanence test again. This time he is able to find the object after longer time periods and still shows great interest in the game! This time he is more prepared to check uncommon hiding places for the object and is hard to trick. He thinks this game is fun and wants to play over and over. (pg. 145) -
12 Months
Jack's capacity for mental representation or symbolic thought has grown tremendously. He is able to imagine where objects he can't see might be. He performs actions such as pretending to drive a car or cook dinner after witnessing scenes being done before. (pg. 144 & 147)
