Consciousness Influence of William James Pioneering Psychologist: William James, known as the father of American psychology, began his journey by delivering a foundational psychology lecture, shaping early psychological thought (Hothersall, 1995). Continuity of Consciousness Dynamic View: James rejected the idea of consciousness as static and fragmented. He compared it to a river, highlighting its fluid and interconnected nature (James, 1890/1970). This perspective emphasizes how our cognitive experiences continuously flow and interact with the world. Key States of Consciousness 1. Focused Awareness ○ Selective Attention: Consciousness involves a selective focus on specific stimuli while filtering out others. ○ Heightened Alertness: In this state, individuals are fully engaged and immersed in tasks, enhancing performance and productivity. 2. Drifting Consciousness ○ Daydreaming: This state is characterized by wandering thoughts, fantasies, and distractions occurring even when awake. 3. Divided Consciousness ○ Simultaneous Activities: Occurs when performing two activities that each demands attention (e.g., multitasking). ○ Inattentional Blindness: A phenomenon where significant events go unnoticed due to focused attention elsewhere. ○ Altered States: Changes in awareness can result from daydreaming, meditation, hypnosis, or the use of substances. Sleeping and Dreaming 1. Circadian Rhythms: These biological systems govern sleep and wakefulness, impacting bodily functions and exhibiting daily fluctuations. The suprachiasmatic nucleus (SCN) in the hypothalamus serves as an internal clock regulating sleep-wake rhythms. 2. Stages of Sleep: Sleep consists of several stages, ranging from light to deep sleep, crucial for restorative processes. 3. REM Sleep: ○ Characterized by rapid eye movement, this stage is associated with vivid dreaming, while dreams in non-REM (NREM) sleep tend to be shorter and less intense. Functions of Sleep Protective Function: Keeps organisms safe during vulnerable periods. Energy Conservation: Allows the body to conserve energy during rest. Restorative Function: Essential for bodily repair and maintenance. Memory Consolidation: Crucial for integrating daily experiences into long-term memory. Dreams and Their Nature 1. Nature of Dreams: Dreams facilitate problem-solving and emotional processing (Hartmann). 2. Activation-Synthesis Hypothesis: Proposes that dreams arise from the brain's effort to make sense of spontaneous neural activity during REM sleep. Freud's Perspective on Dreams Royal Road to the Unconscious: Freud viewed dreams as having hidden meanings expressed through symbols, distinguishing between: ○ Manifest Content: The actual storyline of the dream. ○ Latent Content: The underlying, often concealed meaning. Lucid Dreams Definition: A phenomenon where individuals are aware they are dreaming, potentially indicating greater self-reflection. Sleep Deprivation Adults typically need 7 to 9 hours of sleep, but many college students report getting only 6 to 6.9 hours. Sleep needs vary across the lifespan, with newborns requiring much more REM sleep than adults. Sleep-Wake Disorders 1. Insomnia: Chronic difficulty in falling or staying asleep. 2. Narcolepsy: Sudden, involuntary sleep episodes during the day. 3. Sleep Apnea: Interruption of breathing during sleep. 4. Nightmare and Sleep Terror Disorders: Involves frequent disturbing dreams and episodes of terror. 5. Sleepwalking Disorder: Involves walking or performing complex behaviors while asleep. Altering Consciousness through Meditation and Hypnosis 1. Hypnosis: An altered state characterized by focused attention, deep relaxation, and heightened susceptibility to suggestion. 2. Hypnotic Experiences: These can include posthypnotic amnesia and suggestions that affect behavior after the session. 3. Theories of Hypnosis: ○ Role-Playing Model: Suggests that hypnosis involves social interaction where the subject complies with the hypnotist's commands. ○ Neodissociation Theory: Proposes a split in consciousness, where one part responds to suggestions while another remains aware of external stimuli. Altering Consciousness through Drugs 1. Psychoactive Drugs: Substances that influence brain functioning, altering emotions, thoughts, and behaviors. 2. Drug Abuse and Dependence: Repeated drug use resulting in personal or health issues may lead to dependence. Factors in Drug Use and Abuse 1. Social Factors: Alienation, lack of employment, and cultural influences. 2. Biological Factors: Genetic predispositions affecting neurotransmitter systems. 3. Psychological Factors: Feelings of hopelessness and a desire for escape contribute to substance abuse.
