Cognitive Neuroscience
The study of the interaction between social life and neurological processes.
Memory
The study of which parts of the brain are active when trying to remember past events.
Dual Processing
Daniel Kahneman’s theory that describes two systems of thinking.
System 1
Quick, automatic, instinctive thinking that requires little or no effort.
System 2
Slower, effortful, and complex thinking.
Controlled Processing
Mental processes that require attention and effort.
Serial Processing
A type of processing that is slower and involves processing items one by one.
Parallel Processing
A type of processing that is faster and involves handling multiple items at once.
Waking Consciousness
The state of being aware and active.
Preconsciousness
Mental processes that are not in conscious awareness but can be retrieved.
Unconsciousness
Mental processes that are inaccessible but influence feelings, behavior, and thoughts.
Altered State of Consciousness
A state of consciousness that differs from normal waking consciousness, often induced by substances like alcohol or drugs.
Circadian Rhythms
Biological processes that follow a daily cycle, primarily responding to light and dark.
Suprachiasmatic Nucleus (SCN)
A part of the brain that regulates circadian rhythms and prevents melatonin production in response to light.
Melatonin
A hormone produced by the pineal gland that regulates sleep-wake cycles.
REM Sleep
A sleep stage characterized by rapid eye movement, increased brain activity, and vivid dreams.
Eugene Aserinsky
The researcher who discovered REM sleep using an EEG on his son in 1952.
Polysomnography
A comprehensive sleep study used to diagnose sleep disorders and monitor sleep cycles.
Gamma Waves
Brain waves associated with intense mental activity and problem-solving.
Delta Waves
Slow brain waves present in deep sleep, particularly in stages N3/N4.
Theta Waves
Brain waves that dominate during light sleep, often accompanied by sleep spindles.
Hypnagogic Transition
The transition phase between wakefulness and sleep, often marked by falling asleep.
Sleep Spindles
Sudden bursts of increased frequency in theta brain waves that occur during sleep.
Parasomnia
Disorders characterized by abnormal behaviors during sleep, such as sleepwalking.
Freud's Latent Content
The underlying meaning of a dream according to Freud's dream interpretation.
Manifest Content
The remembered storyline of a dream.
Wish Fulfillment
Freud's theory that dreams represent subconscious desires and thoughts.
Memory Enhancement
The idea that dreaming can improve performance on tasks and assist in memory processing.
Cognitive Filtering
The process by which dreaming helps the brain discard unnecessary neural connections.
Emotional Healing
The notion that dreams facilitate healing by allowing individuals to process trauma.
Rehearsing Fight-and-Flight Responses
The evolutionary theory that dreams prepare individuals for emergency situations.
Sleep Deprivation
Insufficient sleep that negatively affects concentration and safety.
Insomnia
A sleep disorder characterized by problems falling or staying asleep.
Narcolepsy
A disorder marked by sudden, uncontrolled sleep attacks, often entering REM sleep.
Sleep Apnea
A disorder where breathing stops intermittently during sleep.
Night Terrors
Episodes of intense fear while sleeping, often waking the person from nightmares.
Dyssomnia
A broader term for sleep disorders that prevent falling or staying asleep.
Episodic Memory
The memory system that involves recalling specific events.
Procedural Memory
The type of memory related to skills and tasks, often referred to as muscle memory.
Informational Memory
The memory resulting from learning and retaining information.
Continuous Activation Theory
The theory suggesting sleep helps separate valuable memories from unimportant ones.
