Synaptic pruning (prefrontal cortex)
Myelination (important)
Processing speed
Attention
Memory
Emotional/social networks more sensitive
Self-regulation
HEALTH
Changes in sleep patterns: Due to brain changes
Eating disorders
Increasingly emerging as early as sixth grade

Hypothetico-Deductive Reasoning: Can do both
Late: After age 15
Abstraction
Non verbal problem solving
INFORMATION PROCESSING MODEL
Improved attention
Better able to use problem solving strategies
Meta cognition
Increases speed of processing
Increased memory
SOCIAL COGNITION
Social “Understanding”
Perspective Taking / Being “thoughtful”
Thinking about relationships
Idealism
Egocentric Thought
Personal Fable
Imaginary Audience
