Psych-Consciousness and Sleep Vocab

Define consciousness

• A condition in which a person can respond to a visual stimulus without consciously experiencing it.

• The principle that information is often simultaneously processed on separate conscious and unconscious tracks.

• The interdisciplinary study of the brain activity linked with cognition

• Our subjective awareness of ourselves and our environment

Define cognitive neuroscience

• Our biological clock; regular bodily rhythms that occur on a 24-hour cycle.

• A condition in which a person can respond to a visual stimulus without consciously experiencing it.

• The interdisciplinary study of the brain activity linked with cognition

• Our subjective awareness of ourselves and our environment

Define dual processing

• Our subjective awareness of ourselves and our environment

• The principle that information is often simultaneously processed on separate conscious and unconscious tracks.

• The interdisciplinary study of the brain activity linked with cognition

• Processing multiple aspects of a stimulus or problem simultaneously 

Define blindsight

• The interdisciplinary study of the brain activity linked with cognition

• Processing one aspect of a stimulus or problem at a time; generally used to process new information or to solve difficult problems 

• A condition in which a person can respond to a visual stimulus without consciously 

  experiencing it.

• Processing multiple aspects of a stimulus or problem simultaneously 

Define parallel processing

• A condition in which a person can respond to a visual stimulus without consciously experiencing it.

• Processing multiple aspects of a stimulus or problem simultaneously 

• Processing one aspect of a stimulus or problem at a time; generally used to process new information or to solve difficult problems 

• Our subjective awareness of ourselves and our environment

Define sequential processing

• Processing one aspect of a stimulus or problem at a time; generally used to process new information or to solve difficult problems 

• Processing multiple aspects of a stimulus or problem simultaneously 

• The principle that information is often simultaneously processed on separate conscious and unconscious tracks.

• The interdisciplinary study of the brain activity linked with cognition

Define sleep

• Our biological clock; regular bodily rhythms that occur on a 24-hour cycle.

• A periodic, natural loss of consciousness

• Rapid eye movement sleep; occurring sleep stage during which vivid dream commonly occur

• The relatively slow brain waves of a relaxed, awake state.

Define circadian rhythm

• Our biological clock; regular bodily rhythms that occur on a 24-hour cycle.

• Rapid eye movement sleep; occurring sleep stage during which vivid dream commonly occur

• The relatively slow brain waves of a relaxed, awake state.

• Non-rapid eye movement sleep; encompasses all sleep stages except for REM sleep.

Define REM sleep

• A periodic, natural loss of consciousness

• The relatively slow brain waves of a relaxed, awake state.

• Rapid eye movement sleep; occurring sleep stage during which vivid dream commonly occur

• False sensory experiences, such as seeing something in the absence of an external visual stimulus.

Define alpha waves

• The relatively slow brain waves of a relaxed, awake state.

• The large, slow brain waves associated with deep sleep.

• The tendency for REM sleep to increase following REM sleep deprivation.

• Bizarre experiences, such as jerking or a feeling of falling or floating weightlessly, while transitioning to sleep.
