MOTIVATION AND EMOTION
What’s the difference? Confusing because they usually occur together Emotion the subjective experience of a physiological reaction to a stimulus e.g. anxiety, excitement, disgust, love Motivation: activates a goal-directed behavior hunger, thirst, sex, escape, money, power not necessarily conscious
Q: Function of motivation ? A: For survival: Organisms need to initiate adaptive behaviors Forces to push them in right direction cars & computers can’t do it
VARIETIES OF MOTIVATION How many and what is their origin? Freud – just two Learning theory – reward & punishment Humanistic theory not clear – except Maslow Instincts – too many with no organization
DARWIN’S EVOLUTIONARY THEORY Organizes and explains motivation Motivations maximize reproduction of the species
Mechanism of evolution Sexual reproduction variation Environmental pressures and mate-competition Some survive Namely, those who suit new circumstances Floods Famine War
Creates Diverse Species Many niches in ecosystem Each niche selects for different traits Yields great diversity between species It all happens automatically
Evolutionary Psychology Not just physical differences are selected Also behavior and thinking Our species shows specific psychological tendencies E.g., specific fears and desires
Who survived? The fittest ? –not strength or speed but intelligence The best reproducers ? Must show cross-sex attraction Effective reproducers Must also enjoy nurturance Adaptive qualities depend on gender
Individual Differences Not emphasized in evolutionary theory 3 possibilities 1. Natural variation around ideal mean ? 2. Mutations ? 3. Polymorphisms ?
Gender differences Predictable from evolutionary theory because males and females have different reproductive agendas
Most sex differences are small Except with regard to: physical aggression reproductive preferences Those show large differences Different species? Different planets?
Clark & Hatfield (1989) Students approached by opposite-sex stranger 1. Date ? yes = 50% of males 50% of females 2. Have sex ? yes = 75% of males 0% of females
Let me count the ways Casual sex vs. commitment Sex vs. relationship focus Entertainment choice Interest in nurturance
Which theory ? EP predicts all these differences should occur in every human society Other theories do not
