CONSCIOUSNESS osms.it/consciousness WHAT IS CONSCIOUSNESS? ▪ Awake, responsive state; simultaneous cerebral cortex electrical activity ▪ Associated with stimuli perception, voluntary movement control, high mental processing levels ▪ Superimposed by different neuron activities ▫ E.g. same neurons involved in cognition, motor control ▪ Holistic, interconnected (e.g. memories can be triggered by smells, locations, people, etc.) ▪ Clinically, consciousness used to assess response (range: conscious → coma) ▪ Commonly assessed based on response to stimuli (movements, sounds, touch, etc.) CONSCIOUSNESS STAGES ▪ Alertness: information processing, physical arousal ▪ Sleep: partially unconscious state (reduced sensory activity) ▪ Dreaming: mental experiences during sleep ▪ Altered: hypnosis, meditation, druginduced, brain diseases, age → brain wave activity changes LEARNING osms.it/learning WHAT IS LEARNING? ▪ Respond to stimulus → acquire new/adjust existing knowledge/skills/information/ behaviors ▪ Influenced by single/repeated events ▪ Active process ▫ Absorb knowledge by experiencing, exploring, interacting with world ▪ Begins at birth, ends at death ▪ Can occur in different forms ▪ Affected by internal, external factors ▫ External: genetics, environment ▫ Internal: attention, attitude, goals, values, behavior, emotions ATTENTION osms.it/attention WHAT IS ATTENTION? ▪ Behavioral, cognitive process ▫ Selective concentration on information ▪ Attention placed on subset of all perceived stimuli (e.g. one person in a crowd) 460 OSMOSIS.ORG ▪ Limited by capacity, duration ▪ Involves allocating processing resources (e.g. while multitasking) ▪ Integral component of cognitive system for environmental responses
