Intelligence
the capacity to understand the world, think rationally, and use resources effectively when faced with challenges
g-factor
a way intellegence is emboided, the single general factor that produced intellegence
fluid intelligence
the ability to think logically, reason abstractly, solve problems, and find patterns
used when solving a personal problem or grappling with a political issue
crystallized intelligence
accumulation of information, knowledge, and skills that people have learned through experience and education.
reflects facts we have learned and the information that resides in our long-term memory
theory of mulitple intelligences
Gardner argues that we have a minimum of eight different forms of intelligence: musical, bodily kinesthetic, logical-mathematical, linguistic, spatial, interpersonal, intrapersonal, and naturalist
the lateral prefrontal cortex
activation shows here when people are completing intelligence test questions in both verbal and spatial domains.
thickness of the cerebral cortex
linked to high intelligence
metabolisms
rats show that there may be a link from metabolism and intelligence
practical intelligence
intelligence related to overall success in living
career success
traditional intelligence
academic success
emotional intelligence
set of skills that underlie the accurate assessment, evaluation, expression, and regulation of emotions
emotional skills
intelligence tests
quantify a person's level of intelligence
brain size
NOT head size does show some link with intelligence, comes from Galton
mental age
the age for which a given level of performance is average or typical
intelligence quotient (IQ)
a measure of intelligence that takes into account an individual's mental and chronological age.
IQ= (MA/CA)100
should fit a bell-shaped distribution
IQ tests used in the US
Wechsler Adult Intelligence Scale IV and the same for children
reliability
the consistency of a test in measuring what it is trying to measure
validity
when it actually measures what it is supposed to measure
norms
standards of test performance that permit the comparison of one person's score on a test to the scores of others who have taken the same test
adaptive testing
every person doesn't get the same questions, they get harder and easier as time goes on
intellectual disabilities
occur in 1 to 3 percent of the population
formally defined as a disability characterized by significant limitations in both intellectual functioning and adaptive behavior, which covers many everyday social and practical skills, and originates before the age of 22
mild intellectual disability
have IQ scores ranging from 55 to 69, constitute some 90 percent of all people with intellectual disabilities
moderate intellectual disabilities
IQs of 40 to 54, deficits are obvious early, language and motor skills are lagging behind
severe intellectual disability and profound intellectual disability
IQs of 25 to 39 and under 25 unable to function independently and typically requre care for entire lives

practice of educating students with intellectual deficits and other special needs in regular classes during specific time periods.
full inclusion
total integration of all students into regular classes (even those with intellectual disabilities)
intellectually gifted
2 to 4 perfect of the population
IQ scores greater than 130
do well across almost every domain
bias IQ
members of certain racial and cultural groups consistently score lower on average on traditional intelligence tests than do members of other groups
culture fair IQ test
one that does not discriminate against the members of any minority group, psychologists have tried to devise test items that assess experiences common to all cultures or emphasize questions that do not require language usage
heritability
the degree to which a characteristic is related to inherited genetic factors.
a trait with high heritability is strongly related to genetic factors
flynn effect
named for Flynn researcher, the change in IQ scores amounts to roughly 3-point increase every decade
intelligence is it more nature or nurture
more nature but nurture does play a role
sleep brain activity
measures of electrial activity show that the brain is active during sleep
stage 1 sleep
relatively rapid, low amplitude brain waves. images sometimes appear (hallicinations, jerking) as if we were viewing still photos, although this is not true dreaming
lasts around 5 minutes
stage 2 sleep
makes up half of the total sleep in early 20s, characterized by an even slower, more regular wave pattern. momentary interruptions of sharly pointed, spiky waves called sleep spindles.
difficult to wake someone in stage 2
lasts around 20 minutes
stage 3 sleep
the deepest stage, the brain waves become slower with higher peaks and lower valleys in the wave pattern
people are the least responsive to outside stimulation
lasts 30 minutes
REM sleep
quick back and forth eye movement, occupies 20% of adults total sleeping time
when dreams are most likely to occur in the REM period
stages of sleep
90-100 minute cycles
rebound effect
REM deprived sleepers spend significantly more time in REM sleep then normal
ideas for why we sleep
sleep conserves energy for the daytime, sleep restores and replensishes, sleep helps forgetting, sleep promotes physical growth and development
average sleep
around 7 to 8 hours a night, which is 3 hours less than people would sleep 100 years ago
excessive sleep
linked to health problems like depression, diabetes, and heart disease
women vs men sleeping
women fall asleep more quickly, they sleep for longer, and sleep more deeply
lack of sleep
temporarily is not particularly harmful but makes us feel edgy, slows our reaction times, and lower our preformance on academic and physical tasks
nightmares
unusually frightening dreams that occur fairly often
associated with negative experiences throughout the day like worry and anxiety.
unconscious wish fulfillment theory
Sigmund Freud viewed dreams as a guide to the unconscious, proposed that dreams represent unconscious wishes that dreamers desire to be fulfilled.
symbols represent latent content (example: stairway represents sex)
dreams for survival theory
based in the evolutionary perspective, dreams permit us to reconsider and process during sleep information that is critical for our daily survival
this process is evident in rats
activation-synthesis theory
random electrical energy that the brain produces during REM sleep, possibly a result of changes in the production of particular neurotransmitters. this stimulates memories stored in the brain
dream incubation
external stimuli such as specific visual or audio cues at just the right time can trigger specific dream content - a process called dream incubation.
insomnia
a problem that afflicts as many as 1/3 of all people. difficulty sleeping
sleep apnea
a condition in which a person has difficulty breathing while sleeping
SIDS
Sudden infant death syndrome when normal infants die while sleeping
night terrors

uncontrollable sleeping that occurs for short periods while a person is awake. go straight into rem sleep.
sleeptalking and sleepwalking
occur during sleep 3 sleep, more common in children than adults
circadian rhythms
biological processes that occur regularly on approximately a 24-hour cycle
explains mid-afternoon tiredness and naps (siestas)
suprachiasmatic nucleas (SCN)
controls our circadian rhythms
seasonal affective disorder
form of severe depression which increases during the winter and lift during the rest of the year.
daydreams
fantasies people construct while awake, content is usually related to immediate events in the environment
link between daydreaming and creativity
hypnosis
people under hypnosis are in a trancelike state of heightened susceptibility to the suggestions of others
cannot happen against their will
susceptibility to hypnosis varies, 5-20% cannot be and 15% are easily
divided consciousness
Ernest Hilgard states there are two components of hypnosis, the commands, adn the "hidden observers" being aware of what is going on.
could feel pain but think you feel no pain
hypnosis to solve human problems
controlling pain, reducing smoking, treating psychological disorders, assisting law enforement , improving athletic performance

pyschoative drugs
influence a person's emotions, perceptions and behavior (coffee, beer, etc.)
addictive drugs
produce a biological or psychological dependence (or both) on a drug
biological drug dependence

psychological drug dependence
people believe they need the drug to respond to the stresses of daily living
caffeine
one of many stimulants, used to stay awake
stimulants
drugs whose effect on the central nervous system causes a rise in heart rate, blood pressure, and muscular tension
amphetamines (adderall and meth which are known as speed), cocaine (is rapidly absorbed into the body and takes affect immediately), caffeine, nicotine
nicotine
found In cigarettes, is another stimulant

people with alcohol abuse problems, come to rely on alcohol and continue to drunk even though it causes serious difficulties
morphine and heroin
both are narcotics that increase relaxation and relieve pain and anxiety and are derived from the poppy seed pod
opiates vs opioids
opiates are derived from natural substances, include morphine and heroin, and codeine
opioids are synthetic narcotics such as Vicodin, Percocet, fentanyl and OxyContin (all are created in labs and are prescribed to alleviate pain)
methodne

psychodynamic approaches to personality
based on the idea that personality is primarily unconscious and motivated by inner forces and conflicts about which people have little awareness.
started by Sigmund Freud
psychoanalytic theory
assumes much of our behavior is driven by unconscious determinants.
unconscious
a part of the personality that contains the memories, knowledge, beliefs, urges, drives, and instincts of which the individual is not aware.
much of behavior is controlled by this according to Freud
observing the unconscious
done through clues like slips of tongue (often called a Freudian slip), fantasies, dreams, etc.
preconscious
apart of the unconscious which contains material that is not threatening and is easily brought to mind (like 2+2=4)
instinctual drives
deep in the unconscious
the wishes, desires, demands, and needs that are hidden because of the conflicts and pain they would cause if they were apart of our everyday lives
Freud's personality model
the id (completely unconscious), superego, and ego (both half and half conscious and unconscious)
id
the primitive, instinctual craving and longings
unorganized
from birth relates to hunger, sex, aggression, and irrational impulses
opperates on pleasure principle
ego
rational and logical part of the personality
attempts to balance the id and the realities of the objective/outside world
develops soon after birth
the reality principle
superego
part of the personality that harshly judges the morality of our behavior
includes the conscience - prevents wrong doing
psychosexual stages
Freud's personality development through 5 stages that relate to sexual urges: oral, anal, phallic, latency, genital
fixation
conflicts or concerns that persist beyond Freud's developmental period in which they first occur
oral psychosexual stage
birth to 12-18 months, interest in oral gratification
main conflict is weaning, could result in interest in oral activities (talking, eating, smoking)
anal psychosexual stage
12-18 months to 3 years
learning to potty train so gratification comes from using the bathroom
fixation would be if this was a difficult stage, could result in being very type A or type B
phallic psychosexual stage
age3 to 5-6
interest focuses on the genitals and the pleasure from fondling them
this is where the Oedipal conflict is
latency psychosexual stage
after resolution of Oedipal conflict (around 5-6) until puberty.
sexual interests lay dorminant, even in the unconscious
genital psychosexual stage
puberty to death
focus on sexual feelings and mainly sexual intercourse
oedipal conflict
childs intense, sexual interest in their opposite-sex parent. Stems from the Greek story/myth.
Sons want to get rid of the father (but they are too strong) but end up resonating with them
Daughters resent the mother for castration (missing a penis) but rather end up resonating with them
identification
the process of wanting to be like another person as much as possible, imitating a person's behavior and adopting similar beliefs, attitudes and values (what kids end up doing after Oedipal conflict)
anxiety
an intense emotional experience that Freud considers to be a danger signal to the ego
defense mechanisms
unconsious strategies that people use to reduce anxiey
repression
main defense mechanism
push unpleasant memories to the conscious
regression
defense mechanism
people behave as if they were at an earlier stage of development
temper tantrums
displacement
defense mechanism
expression of unwanted feeling or throught is redirected from a more threatening and powerful person to a weaker one
taking out agression on teacher to brother
rationalization
defense mechanism
people self-justifying explanations in place of the actual, but threatening, reason for their behavior
drinking to avoid homework (make up an excuse for why you are drinking)
denial
defense mechanism
people refuse to accept an anxiety-producing piece of information
ignore a bad grade
projection
defense mechanism
attribute unwanted impulses and feelings to someone else
when someone who is cheating accuses their spouse of cheating
sublimation
defense mechanism
divert unwanted impulses into socially approved thoughts, feelings, or behaviors
a violent person becomes a soldier
reaction formation
defense mechanism
unconscious impluses are expressed as their opposite in consciousness
neglagant parent acts overly loving
neurosis
Freuds term for using too many defense mechanisms that it becomes difficult
neo-Freudian psychoanalysts
originally studied Freuds theories but changed them a little
- rejected sexual urges
- women envy men for their independent, success, and freedom
- motivation for superiority not sex
collective unconsious
Jung's theory that we inherit a set of ideas, feelings, images, and symbols because of humans shared ancestral past

traits
consistent, habitual personality characteristics and behaviors that are displayed across different situations
trait theory
the personality approach that seeks to identify the basic traits necessary to describe personality
trait-theory categories of traits
cardinal, central, and secondary
cardinal traits
a cardinal trait is a single, overriding characterisitic that motivates most of a persons behavior (selfless, power-hungry)
central traits
usually 5-10 but can be less traits that make up a core personality (warmth, friendly)
secondary traits
characterisitics that affect behavior in fewer situations (reluctance to eat meat, love of modern art)
factor analysis
statistical method of identifying patterns among a large number of variables and combining them into more fundamental groupings
example is the 16 factor questionaire by Cattell
factors
fundamental patterns of traits that cluster together in the same person
Eysenck's 3 major dimensions
extraversion: sociability
neuroticism: emotional stability
psychoticism: degree to which reality is distorted (aggression, cold, egocentric, impulsive)

Openness to experience
Conscientiousness
Extraversion
Agreeableness
