    Study Notes

    Consciousness

    • Consciousness refers to our immediate awareness of internal and external states.
    • Early psychologists defined psychology as the study of consciousness.

    States of Consciousness

    • Altered states of consciousness involve changes in awareness of surroundings and internal states.
    • Examples include sleep, dreaming, hypnosis, meditation, anesthesia, and psychoactive drug use.
    • Conscious awareness is divided into states of consciousness and contents of consciousness.
    • States of consciousness refer to our level of awareness of our surroundings and internal states.
    • Contents of consciousness are the specific thoughts we are aware of about our internal states or external surroundings.

    Core Cognitive Processes

    • Attention, memory, reasoning, and problem-solving are core cognitive processes that contribute to consciousness.
    • Attention Blindness occurs when we fail to notice details of a scene or video due to focusing on a specific aspect.
    • Blindsight is a condition where individuals have intact retinas but brain damage prevents vision. They can still respond to visual stimuli without conscious awareness.

    Brain Regions and Consciousness

    • The reticular formation controls wakefulness and alertness.
    • The thalamus and hypothalamus act as signal relays in the brain, filtering and directing information. Damage to the hypothalamus can lead to narcolepsy.
    • The Cerebral Cortex plays a crucial role in visual awareness. Damage to the cortex results in blindness but not loss of consciousness.
    • The synchronized activity of the temporal, parietal, and visual cortex is essential for awareness of objects.
    • The Frontal Lobe is crucial for decision-making and directing attention.

    Development and Consciousness

    • Children develop a sense of self around 18 months, recognizing their distinctness from others.

    Preconscious and Unconscious States

    • Preconsciousness refers to information that is not readily accessible to consciousness but can become available if needed.
    • The Unconscious State involves information beyond easy conscious access. Memories can emerge later unexpectedly.

    Cognitive Views of the Unconscious

    • Cognitive theorists propose two types of memory:
      • Explicit Memory: Conscious and intentional memory retrieval.
      • Implicit Memory: Unconscious knowledge that influences skills, facts, and behavior.

    Freud's Views of the Unconscious

    • Freud believed the unconscious mind contained repressed memories that were too painful to consciously access.
    • These repressed memories could contribute to psychological disorders.

    Why We Sleep

    • Sleep is not simply for brain rest.
    • Adaptive Theory of Sleep: Sleep evolved to protect organisms from predators who are more active at night.
    • Restorative Theory of Sleep: Sleep allows the brain and body to replenish resources and eliminate waste products accumulated during wakefulness.

    Rhythms of Sleep

    • Circadian Rhythm: A natural 24-hour sleep-wake cycle, affected by daylight and darkness. This biological clock can be disrupted by time zone changes and irregular sleep patterns.
    • Circadian Rhythm Sleep Disorder: Disruptions in this cycle can lead to depression and health issues.

    GABA and Sleep

    • GABA is a neurotransmitter released by the hypothalamus that promotes sleep.

    Neuron Activity During Sleep

    • The reticular formation, pons, hypothalamus, and forebrain show changes in neuron activity during sleep.

    Consciousness

    • Turing Test: Evaluates if an AI exhibits human-like consciousness by engaging in a conversation with a person. If the AI convinces over 30% of participants it's human, it passes the test.
    • Consciousness: Immediate awareness of internal and external states.
    • Altered States of Consciousness: Changes in awareness of surroundings and internal states; examples include sleep, dreams, hypnosis, meditation, anesthesia, and drug-induced states.

    Conscious Awareness

    • States of consciousness: Level of awareness of external and internal states.
    • Contents of consciousness: Specific thoughts about internal and external states.
    • Core cognitive processes: Attention, memory, reasoning, problem-solving.
    • Attention Blindness: Inability to detect details in a scene when focused on a specific aspect, demonstrated through the "gorilla" experiment.
    • Blindsight: Intact retinas with brain damage, resulting in blindness but the ability to point towards light shone in the eyes.

    Brain Regions and Consciousness

    • Reticular Formation: Controls wakefulness and alertness.
    • Thalamus & Hypothalamus: "Subway lines" of the brain, processing information and directing focus. Damage to the hypothalamus can lead to narcolepsy.
    • Cerebral Cortex: Responsible for visual awareness. Damage results in blindness, but the person remains awake.
    • Frontal Lobe: Critical in deciding what to focus on.

    Development and Consciousness

    • Self Awareness: Develops around 18 months in children.

    Preconscious and Unconscious States

    • Preconsciousness: Information readily available to conscious awareness.
    • Unconscious State: Information not easily accessible to conscious awareness.

    Cognitive Views of the Unconscious

    • Implicit Memory: Unconscious processing of knowledge used in skills and factual information, like playing an instrument or riding a bike.
    • Explicit Memory: Consciously recalling information like specific dates.

    Freud's Views of the Unconscious

    • The unconscious is a repository of repressed memories, potentially leading to psychological disorders if excessive repression occurs.
