strength based selection system
identify a group of most effective people and compare their strengths with those of a group of least effective people - matching people's strengths with work enables them to flourish = prosperity & profit

just world phenomenon
the tendency for people to believe the world is just and that people therefore get what they deserve and deserve what they get - good is rewarded & evil is punished - leads to blaming the victim - feeds on hindsight bias
foot-in-door phenomenon

ATKINSON - SHIFFRIN
- birth of cognitive psychology Atkinson Shiffrin Model (1968) - stimuli is recorded and held in our sensory memory (what we hear, see, smell, taste, touch) - some information is processed into short term memory (lasts a couple of min/hours/days = working memory) & encoded through rehearsal (information is repeated over and over as a possible way of learning and remembering it - information then moves into long term memory (information that can be retrieved later)
hypothalamus
- blood vessels connect the hypothalamus to the rest of the body so it can respond to our current blood chemistry & other incoming information - one of its tasks is to monitor levels of appetite hormones
why we forget
- brain damage --> anterograde & retrograde amnesia - encoding failure --> did not pay attention of sensory memory to hold in working memory/ didn't rehearse it and encode it into long term memory - storage decay --> material in long-term memory will decay if memory is never used, recalled, or restored (LTP in reverse --> unused connections & networks decay) - retrieval failure --> the associations and links that help us find our way to the stored memory decay ("tip of the tongue") - interference --> proactive (old memory interferes) & retroactive (new memory interferes) interference - motivated forgetting --> choosing to forget or change our memories
correlations with "genius"

culture-bound syndromes
- disorders which only seem to exist within certain cultures; they demonstrate how culture can play a role in both causing and defining a disorder - genetic influence are lower in culture-bound disorders
social networking (POSITIVE)
- diversifies our social networks - strengthens bonds with people we already know - electronic communication eliminates shyness - sharing feelings is easier
maternal virus
- during the second trimester, if the mother has had the flu then the baby has a chance of developing schizophrenia in the womb. - maternal virus during mid-pregnancy impairs brain development - schizophrenia is more likely to develop after and during flu epidemics
separating the brain hemispheres
- each hemisphere controls the opposite side of the body AND is aware of the visual field on that opposite side - without the corpus callosum --> halves of the body and the halves of the visual field don't work together - only the left half of the brain has enough verbal ability to express its thoughts out loud
HENRY MOLAISON
- endured experimentally drastic surgery --> removed hippocampus to get rid of his seizures effect: - couldn't make new explicit memories - experienced anterograde amnesia - ended seizures - retained memories from before the surgery

- homosexuality is not associated with mental disorders or emotional/social problems - homosexuals are not aware of same-sex attraction until around the time of puberty - women's sexual drive & interests are more flexible and varying than men
twin & adoption studies
- identical twins raised together = highest similarity - fraternal twins raised together is higher similarity than siblings raised together - adopted kids raised together = lowest similarity (nature plays a bigger role in adoption studies) - intelligence scores of adoptees looks more and more like their biological parents

Why do we need memory?
- retain useful skills, knowledge & expertise - recognize familiar people & places - build capacity to use language - enjoy, share, and sustain culture - learn from experience
Individualism values
- self = independent(identity from individual traits) - life task = discover and express one's uniqueness - what matters = me- personal achievement and fulfillment; rights and liberties; self-esteem - coping method = change reality - morality = defined by individuals (self-based) - relationships = many, often temporary or casual; confrontation acceptable - attributing behavior = behavior reflects one's personality and attitudes
collectivism values
- self = interdependent (identity from belonging) - life task = maintain connections, fit in, preform role - what matters = us- group goals and solidarity; social responsibilities and relationships; family duty - coping method = accommodate to reality - morality = defined by social networks (duty based) - relationships = few, close and enduring; harmony valued - attributing behavior = behavior reflects social norms and roles
physiology behind weight
- set point & metabolism - genetics - sleep loss (leptin levels fall & ghrelin levels rises) - social influence - less activity (more sedentary jobs) & more food (bigger portions)
