Cognitive neuroscience: the interdisciplinary study of the brain activity linked with cognition
(including perception thinking, memory, and language). Looked at by psychologists,
sociologists, biologists, etc.
Consciousness:
Alertness; being awake vs. being unconscious
Self-awareness; the ability to think about self
Having free will; being able to make a “conscious” decision
A person’s mental content, thoughts, and imaginings.

Dual-track mind
Conscious “high” track:

oExample: Hitting a ball, learning how to ride a bike
Unconscious “low” track
oOur minds perform automatic actions, often without being aware of them.
oExamples – breathing, walking, developing fears, memories, riding a bike after
you have already learned, reading.
