Cumulative part of the Final Flashcards
Nature vs nurture
What is the product of environment and what is the product of genetics?
Current Perspectives of Psychology
Neuroscience, Evolutionary, Behavior Genetics (nature v nurture), Psychodynamic (Freud), Behavioral, Cognitive, and Social-cultural
Psychologist
Treats, assesses, and treats people, researches
Psychiatrist
medical emphasis
Hindsight Bias
Tendency to believe we would have seen the outcome
Critical Thinking
Examine, discern, evaluate, and assess info
Scientific method
Theory> hypothesis> testing> replication
Theory
Explanation that predicts behavior
Hypothesis
Testable prediction
Operational definition
Procedures used to define research variables
Replication
Repeating the study
Random sample
Everyone has an equal chance of being selected
Representative sample
Representative of the population
Case study
Study few individuals in great detail
Survey
More people with less detail
Wording effects
Need clear, unbiased wording
Naturalistic observation
Observing and recording info in a natural setting
Positive correlation
Both variables increase
Negative correlation
One variable increases while the other decreases
Illusory correlations
Believe there’s a relationship when there’s not
Experiment
Manipulate one variable and control for all others
Random assignment
Randomly assign people to groups
Independent variable
Variable that is manipulated
Dependent variable
Variable that is measured
Neuron
Nerve cell
Dendrite
Receive incoming info
Axon
Passes info on
Action potential
Electrical charge starting at dendrites and leaving through axon
Treshold
All or none
Synapse
Space between neurons
Vesicles
Release neurotransmitters
Neurotransmitters
Chemical that cross synapses
Acetycholene
Go from motor neurons to muscle
Endorphins
Natural Pain killer
Epinephrine
Adrenaline
Norepinephrine
Noradrenaline
Nervous System
Brain and nerves
CNS
Brain and spinal cord
PNS
Rest of nervous system
Somatic Nervous System
Transmits sensory input and directs voluntary motor output
Autonomic Nervous System
Automatic things
Sympathetic Nervous System
Arouses body
Parasympathetic Nervous System
Calms body down
Sensory neurons
Bring in sensory info
Interneurons
In CNS, communicate internally
Motor Neurons
Relay instructions, cause reactions
Brainstem
Reticular formation, medulla, cerebellum, and thalamus
Medulla
Controls heart and breathing
Thalamus
Passes info from the brainstem to the cerebral cortex
Reticular Formation
Connects the spinal cord to the thalamus and controls arousal and sleep
Cerebellum
Base of the brain which controls voluntary motor movement and balance
Corpus Callosum
Connects hemispheres
Limbic System
Hippocampus, amygdala, and hypothalamus
Amygdala
Controls agression and fear
Hypothalamus
Below thalamus, Regulates pituitary gland temperature, thirst, and pleasure
Cerebral Cortex
All lobes
Frontal Lobe
Front of brain, Planning, decision making, personality
Occipital Lobe
Base of brain, visual info
Temporal Lobe
Auditory info
Parietal Lobe
Association areas
Motor Cortex
Sends outgoing messages for motor movement
Sensory Cortex
Receives sensory input from body
Association Areas
Routes info to the correct parts of the brain
Brain Plasticity
Ability of brain to modify itself after damage
Split Brain
Cut corpus callosum
Behavior Genetics
Genetics and environment on behavior
Twin Studies
Study identical twins separated at birth
Evolutionary Psychology
Study evolution on psychology
Natural Selection
Superior traits passed on
Consciousness
Awareness of self and environment
Selective Attention
Attention focused on small part of incoming stimuli
Circadian Rhythm
Internal biologica clock
Sleep Stages
Awake, stage 1, stage 2, stage 3, REM
Sleep cycles
10/90 minutes of sleep is REM
Insomnia
Recurring problems falling and staying asleep
Narcolepsy
Bizarre periodic lapses directly into REM
Sleep apnea
Stop breathing while sleeping momentarily
Night terrors
Immense terror during sleep, no plot, no memory
Manifest content
Story line
Latent content
Underlying meaning
Hypnosis
Induced temporary state of heightened suggestibility
Dissociation
Split consciousness
Drug Tolerance
Takes more of drug to get desired effect
Physical Dependence
Physiological need for the drug; pain and cravings
Psychological Dependence
Need the drug to feel a certain way
Addiction
When someone physically needs the drug
Withdrawal
Discomfort and distress experienced when someone stops taking a drug
Psychoactive Drugs
Drugs that affect the Nervous System
Depressants
Slow system down; Alcohol, barbiturates, Opiates
Stimulants
Excite system; meth, caffeine, nicotine, cocaine, ecstacy
Hallucinogens
Perception without stimulation; Marijuana and LSD
Alcohol
Slows reactions, lowers inhibitions, makes sleepy
Barbiturates
Tranquilizer, impairs memory
Opiates
Opium, morphine, heroin, painkillers, OD stop breathing, addictive
Meth
Triggers dopamine release
Caffeine
Increases energy, widely used, tolerance and withdrawal
Nicotine
Addictive, tolerance, releases epinephrine, endorphins, and norepinephrine, energy boost, makes alert and calm
Cocaine
Blocks re-uptake of dopamine, norepinephrine, and serotonin, euphoric rush, crash, aggression, crack is more intense
Ecstacy (MDMA)
Hallucinogen and stimulant, blocks re-uptake of serotonin, 3-4 hr high, increase in feelings of intimacy, permanently damages serotonin production, permanent memory damage
Marijuana
Amplifies sensations, not physically addictive, but psychologically, interferes with memory formation, stays in system for a week
LSD
Blocks serotonin, expectations influence experience, shapes to out of body experience, low oxygen intake
Stage 1 Sleep
Drowsing off
Stage 2 Sleep
Small bursts of brain activity; spindles
Stage 3 Sleep
Deep sleep; sleep walking, bed wetting
REM
Actively dreaming, body paralyzed
Developmental Psychology
Studies change through the lifespan
Prenatal Development
Vulnerable to teratogens, embryo to fetus etc
Maturation
Orderly sequence of biological growth
Critical period
Optimal period when exposure produces normal development
Cognition
Thinking, knowing and remembering
