Consciousness in psychology refers to our awareness of internal and external stimuli. It includes our ability to feel pain, hunger, thirst, sleepiness, and be aware of our thoughts and emotions. It also includes our experiences of seeing, feeling, and hearing external stimuli. Consciousness is a continuum that ranges from full awareness to a deep sleep. Wakefulness is characterized by high levels of sensory awareness, thought, and behavior, while sleep is marked by relatively low levels of physical activity and reduced sensory awareness.

Consciousness is a complex and vast subject that draws on the latest advances in multidisciplinary research. It is not found lying in physics equations or peering at us from the periodic table. Instead, it materializes out of the nervous system and endows us with the ability to be aware, have self-knowledge, and hold a set of emotions and beliefs about both the environment and ourselves.

There are many different states of consciousness that people experience, including daydreaming, intoxication, and unconsciousness due to anesthesia. Consciousness is dependent on many unconscious, specialized processes that operate in parallel, such as motion, depth perception, and color.

In summary, consciousness in psychology refers to our awareness of internal and external stimuli, and it is a complex and vast subject that draws on the latest advances in multidisciplinary research.
