Consciousness

Different ways of orienting to internal and external events, such as awake states and sleep states

The subjective awareness of mental events

The process of focusing consciousness on a limited range of experience

The process by which important information is ignored

The process by which attention is split between two or more sets of stimuli

A procedure in which different information is presented to the left and right ears simultaneously

Turning attention away from external stimuli to internal thoughts and imagined scenarios

A research technique whereby participants report on the contents of consciousness at specified times

An experience-sampling technique that has provided a more natural window to the flow of consciousness in everyday life

Processes that involve a subjective awareness to stimuli, feelings or ideas

Thoughts that are not conscious but could become conscious at any point, much like information stored in long-term semantic memory

In Freud’s theory, mental processes that are inaccessible to consciousness, many of which are repressed

Perception of stimuli below the threshold of consciousness

Information processing mechanisms that operate outside of awareness, such as procedural memory and implicit associative processes, as opposed to the psychodynamic unconscious, which includes information the person is motivated to keep from awareness

The inability to sleep

Biological rhythm that evolved around the daily cycles of light and dark

The period of sleep in which darting eye movements occur, autonomic activity increases, and patterns of brain activity resemble those observed in waking state

States of sleep in which rapid eye movement (REM) is not present
