changes associated with it (not the case) ­ Supporting evidence: facial and behavioral feedback phenomena (when changes in facial/behavioral expression produce a corresponding change in emotion) ­ Application: lie detection ­ Polygraph ­ Measures autonomic activity ­ Assumption: if polygraph shows physiological arousal, subject is lying ­ Problem: measures arousal, not lying ­ Validity: cannot distinguish between different types of arousal ­ Individual variations ­ Error rate: 33% ­ More likely to label innocent people as guilty than guilty people as innocent ­ Excluded/restricted in court ­ Cannon­Bard theory ­ Event ­­> nonspecific physiological/behavioral changes and emotion (neither one causes the other) ­ Schacter and Singer's Two­Factor theory ­ Event ­­> nonspecific

(correlation): social relationships, resources, religion, and health ­ Factors unrelated: age, gender, and physical attractiveness ­ Money buys happiness if you have no money ­ Diminishing returns ­ Spending on experiences increases happiness more than spending on things, and people are happier after spending money on someone else rather than spending money on themselves ­ Social comparisons: comparing self with someone who has less leads to satisfaction, but comparing self with someone who has more leads to self­deprivation ­ Also observed in animals ­ How much impact an event has on our happiness depends on our experiences/what we're used to ­ Adaptation­level phenomenon: tendency to judge new stimuli/events in relation to what we have recently experienced ­ We adjust to new circumstances until they become neutral ­ We always want more than what we have ­ Major events often don't have as much of an impact on or happiness as we think they will (ex. winning the lottery or

period ­ 2­7 years ­ Egocentrism: not knowing that other people don't know what you know/see what you see ­ Lack of theory of mind: the ability to take another person's perspective (other people have different thoughts) ­ Develops around 4 months ­ Continued difficulty for autistic kids ­ Difficulty with mental operations ­ Lack of conservation: understanding that quantity stays the same even if appearance changes ­ Concrete operational period ­ 7 years ­ adolescence ­ Understand conservation ­ Can perform simple mental operations ­ Limited to concrete objects ­ Formal operational period ­ Adolescence ­ Abstract, hypothetical thinking ­ Systematic, logical reasoning ­ Piaget's theory today ­ Sequence is correct, but he underestimated the timing (kids know more sooner than what Piaget's stages indicated) ­ More gradual change than stages imply ­ Some people suggest stages should be added (teens vs. adults) ­ Social and emotional development in childhood ­ Temperament: behavioral and

negative emotion, irregular, irritable ­ Slow­to­warm­up babies: in between easy and difficult ­ Attachment: a close emotional bond ­ Causes: food used to be believed to be the cause, but Harlow's studies implied contact comfort had to do with attachment ­ Harlow's monkeys raised in isolation from their mother ­ Cloth vs. wire mother ­ Monkeys spent time clinging to cloth mother even if wire mother provided food ­ Contact comfort vs. nourishment ­ Less distressed when taken away from mothers if monkeys can still touch the mother ­ Harlow's monkeys didn't make good mothers which suggests there isn't a maternal instinct ­ Premature babies can leave hospital faster if they are massaged
