Unit Exam 2 Flashcards
Consciousness
An organisms awareness of its own self and surroundings
Alternate states of consciousness (ASC)
Mental states found during sleep, dreaming, psychoactive drug use, hypnosis, etc
Low Level of Awareness
Sleeping, dreaming, anesthesia, coma
Middle Awareness
Automatic processing for activities that require minimal attention
IE walking while talking on the phone
High Awareness
Controlled processing for activities that require focus, like learning to drive
Circadian Rhythms
Fluctuation of things such as alertness or body temperature in fairly regular 24 hour cycles
Can be easily disrupted
Sleep Deprivation
Not getting enough sleep
Leads to significant mood alterations, decreased self esteem, reduced concentration, motivation, and motor skills, increased irritability and cortisol, lapses in attention
Sleep cycle
5 Steps
4 steps of NREM and 1 REM
Repeats about 4-5 times per night
REM Sleep
Stage of sleep marked by rapid eye movement, high frequency brain waves, paralysis of large muscles, dreaming
Important for learning and consolidation of memories
NREM
Stages 1-4 of sleep with stage 1 as the lightest level and stage 4 as the deepest level
Need for NREM is satisfied before REM
Adaption/Protection Theory
Sleep evolved to conserve energy and as a protection from predators; also served as part of the circadian cycle
Repair/Restoration Theory
Sleep serves a recuperative function, allowing organisms to repair or replenish key factors
Growth/Development Theory
Sleep coincides with the release of growth hormones from the pituitary gland, and we need less sleep as we age because we grow less
Learning/Memory Theory
Sleep is important for learning and the consolidation, storage, and maintenance of memories
Wish Fulfullment Theory
Our dreams are our unconscious desires and thoughts coming to the surface (manifest, latent content)
Activation-Synthesis Hypothesis
Dreams are random brain activity. Your personality, motivations, memories, and experiences guide the construction of dreams
Information Processing Idea
Dreams allow us to process, assimilate, and update information in our brain
Insomnia
Persistent difficulty falling or staying asleep
Narcolepsy
Sudden, irresistible onset of sleep during waking hours
Sleep Apnea
Repeated interruption of breathing while asleep
Nightmares
Bad dreams during REM sleep
Night terrors
Abrupt awakenings with feelings of panic during NREM
Psychoactive drugs
Chemicals that change conscious awareness, mood, or perception
Drug Abuse
Drug use that causes emotional or physical harm to the user or others
Addiction
Broad term describing a compulsion to use the specific drug or engage in a certain activity
Psychological Dependence
Mental desire or craving to achieve a drugs affect
Physical dependence
Changes and bodily processes that make the drug necessary for minimum daily functioning
Tolerance
Bodily adjustment to higher and higher levels of a drug which leads to decreased sensitivity
Cross Tolerence
When using one drug increases tolerance for another drug
Withdrawal
Discomfort and distress, including physical pain and intense cravings, experienced after stopping the use of addictive drugs
Agonist Drugs
Drugs which enhance the synaptic transmission they increase the neuron’s ability to synthesize more transmitter molecules, bind to the receptor to send more signals, and block reuptake
Antagonist Drugs
Inhibit synaptic transmission
Block the receptor site and decrease the neurons ability to synthesize, store, and release neurotransmitters
Depressants
Drugs that act on the CNS to suppress or slow bodily processes and reduce overall responsiveness
Ex alcohol
Stimulants
Drugs that act on the brain and NS to increase overall activity and general responsiveness
Ex caffeine
Opiates
Drugs derived from opium that mimic the brains natural endorphins, which numb pain and elevate mood. Aka narcotics. Over time they decrease our ability to create our own endorphins
Ex heroin
Hallucinogens
Drugs that produce sensory or perceptual distortions called hallucinations
Aka psychedelics
Ex LSD
Club Drugs
Psychoactive drugs commonly used at parties or clubs
Meditation
Group of techniques designed of refocus attention, block out distractions, and produce an altered state of consciousness
Flow
Being in the zone; when you enter an activity where you lose track of time because you are zoned in
Hypnosis
Trance like state of heightened suggestibility, deep relaxation, and intense focus
Learning
Relatively permanent change in behaviour or mental processes caused by experience
Conditioning
Process of learning associations between stimuli and behavioural responses
Classical conditioning
Involuntary
Learning through involuntary paired associations
Occurs when a NS is paired with an US to elicit a CR
Unconditioned stimulus
An unlearned stimulus that naturally and automatically elicits a UR without previous conditioning
Unconditioned response
Unlearned reaction to a US without previous conditioning
Neutral stimulus
Stimulus that prior to conditioning does not naturally bring around the response of interest
Conditioned stimulus
Previously NS that through repeated pairing with an US now elicits a CR
Conditioned response
Learned reaction to a CS that occurs because of repeated pairings with an US
Conditioned Emotional Response
Classically conditioned emotional response to a previously neutral stimulus
Watson and Classical Conditioning
Proposed that likes, dislikes, phobias, prejudices, and love are a result of conditioning
6 Principle of Classical Conditioning
Acquisition Stimulus Generalization Stimulus Discrimination Extinction Spontaneous Recovery Higher Order Conditioning
Acquisition
NS and US are paired, and the NS become the CS, eliciting a CR
Stimulus Generalization
CR is elicited not only by the CS, but also by stimuli similar to the CS
Stimulus Discrimination
Certain stimuli similar to the CS do not elicit the CR
Extinction
CS is presented alone without the US; eventually the CS no longer elicits the CR
Spontaneous Recovery
Sudden reappearance of a previously extinguished CR
Higher Order Conditioning
NS becomes CS through repeated pairing with a previous CR
Operant Conditioning
Voluntary
Learning through voluntary responses and their consequences
Reinforcement increases behavioural tendencies whereas punishment decreases them
Reinforcement
A consequence that strengthens a response and makes it more likely to occur
Punishment
A consequence that weakens a response and makes it less likely to occur
Primary Reinforcers
Inherently valuable reinforcers; we don’t need to learn that these things are good
Secondary reinforcers
It doesn’t have value until we are taught what they mean/are worth
Positive reinforcement
Adding something to increase behaviour
Negative reinforcement
Take away something to increase behaviour
