States of consciousness differing from normal waking state, achieved through various means.

A natural 24-hour cycle in biological processes, regulating sleep and wakefulness.

Method of tracking thoughts through notifications, assessing focus on tasks.

Failure to notice significant changes in a visual scene due to attention constraints.

Stimuli below conscious awareness that can influence thoughts or behaviors.

A person's subjective experience of the world and mind.

Basic sensory awareness and responsiveness, driven by unconscious processes.

Mental processes that influence thoughts and behaviors without one’s awareness.

Awareness of mental state and thoughts, including meta-cognition (thinking about thinking).

Subjective experiences of sensations, how something feels to an individual.

Inability to perceive one side of the visual field due to brain damage.

Failure to shift attention from a target in one visual field when another is present.

Consciousness involves intentionality, unity, selectivity, and transience.

A task measuring the ability to focus attention and filter out competing stimuli using different sounds in each ear.

A task to study attention where participants respond to targets in different locations, influenced by pre-cues that may or may not predict the target's location.

The effectiveness of a cue in predicting a target's location, affecting reaction times based on whether cues are valid, invalid, or neutral.

The tendency for people to have thoughts unrelated to their tasks about 20-50% of the time while awake.

The inability to completely suppress thoughts; trying to do so can lead to stronger thoughts due to the rebound effect.

The awareness of oneself as an object, developing through life, often tested by recognition in mirrors.

A phenomenon where a person feels like a rubber hand is part of their body due to visual and tactile experiences being synchronized.

Different phases of sleep characterized by distinct brain wave patterns, from awake to REM sleep.

Electroencephalography measures electrical brain activity.

A sleep stage characterized by rapid eye movement and dreaming.

The process of strengthening newly formed memories during sleep.

Suggests dreams reveal hidden wishes and desires.

Hobson and McCarley's theory that dreams are the brain's attempt to interpret random neural activity.

Dreams often present a reality that differs wildly from waking life.

Increased activity in the motor cortex while dreaming, despite physical immobility.
