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.
