Consciousness

awareness of events around us and our internal world

Introspection

observing one's own conscious expereince and describing

Synesthesia

people experience infortmation from one sensory as if were coming through multiple senses, Varies amoungst individuals

key awareness

arousal (wakefulness or alterness), awareness

Sekective attention

prioritizing awareness of relavant information

Inattentional blindness

Occurs prioritizing awareness of relavant information

Inattentional blindness

occurs when people fail to see things outside their focus of attention

Automaticity

The ability to perform complex activities with minimal conscious awareness

Mind Wandering

help organize and structure plans

unconscious mind

monitor, understand, and respond to experiences without awareness

Conscious awareness

focuses on current awareness

Preconscious

consciously accessible thoughts, feelings, and memories

Dynamic Unconscious

inaccesible memories, instincts, and desires

congnitive unconscious

perception, memory, and thinking without conscious awareness

Thalamus

reticular activating system, controls alertness

Frontal and Parietal lobes

involved in focused and slective attention

default mode network

more active during mind wandering

Hippocampus

active during thinking and mind wandering

Global workspace hypothesis

suggest conscious awareness arises from synchronized brain activity

circadian rhythm

synchronizes arousal levels to 24 hour cycle

Suprachiasmatic nucleus

adjusts arousal patterns to fit the current schedule

Stage 1

hallucinations, floating sensations, and falling

Stage 2

rapid rhythmic brain

Stage 3

deeper sleep and delta waves

REM (rapid eye movement )

sleep occurs about an hour after faling asleep and is considered paradoxical

Sleep

helps animals stay safe, conserve resources, learn, and remember

Animals

adjust their sleep patterns based on survival risks

Dreams are often ongoing life events and may contain negative emotions

REM Rebound

leads to increase REM sleep and deprivation

Manifest Content

Uncensored, symbolic version of latent content representing unconscious drive and wishes

Activation

Synthesis

Psychoactive drugs

influence consciousness by altering brain chemical messages

Drug Tolerance

leads to higher doses for the same effect

drug addiction

Physical Dependence and Withdraw

Depressants

Lower nervous system activity, potentially leading to withdrawal symptoms, decrease nervous system activity, such as alcohol

Stimulants

increase neural activity, caffeine and cocaine

Psychedelics

causes dramatic changes in consciousnees, disorting perception and triggering sensory expericnes LDS

Hyposis

highly relaxes state of mind for therapeutic purposes
