Chapter 2 Flashcards
Evolutionary Perspectives
use principles from evolutionary biology to explain why certain patterns of social behaviour na psychological mechanisms have evolved in animals/humans
-sociobiology: some social behaviours are a result of evolution that benefited our ancestors
evolution (producing viable healthy offspring) occurs via natural selection (best adapted individuals survive and pass on thier genes)
how do humans choose mates
physical attractiveness and physique and complexion may provide hints to the health of the individual in order to have maximum reproductive health
if this is true then it should be even more important in mate selection in societies where more people are unhealthy which is true
in this way showing off at the pool or getting engaged are similar to animal courtship rituals
ie. men pay for dinner and spend money to show they can support a family
Several obstacles before reproductive success
ie. infant vulnerability and maternal death and father protects from harm
two mechanisms that facilitate these conditions are a pair-bond between mother and father and attachment between infant and parent
therefore offsprings chance of survival can depend on how strong these attachments are
canadian fathers invest more in own children or stepchildren or firends children equally
more willing for own children which makes sense with the high rates of divorce and remarriage
stimuli and preferred sex
men show physiological sexual arousal to their preferred sexual partner
female show physiological sexual arousal to both preferred and unpreferred sex partners, and even stimuli of animals
maybe the automatic lubrication has been naturally selected for to reduce risk of injury during sex with a range of stimuli
Darwin also proposed sexual selection
definition: selection that results from differences in traits affecting access to mates.
two processes: competition among members of one gender (usually males) for mating access to members of the other gender AND preferential choice by members of one gender (usually females) for certain members of the other gender
therefore men show off in various ways more often than females
criticisms of sociobiology:
outdated basis, individual struggles rather than species survival, and that the central function of sex is reproduction
ie. playboy models hips are getting skinnier which doesnt present an evolutionary advantage
evolutionary psychology
how natural selection has shaped psychological mechanisms and processes aka the mind over how it has shaped it directly
women compete with other women so those who are sexually available for males short-term goals negatively affects women pursuing long term strategy
those with short term goals would choose sexier clothing three or more days before or sevevn days after ovulation
criticism of evolutionary psychology
research leads to suggest male and females are very similar in their stated mating preference, both prefer long term
characteristics that seem to have adaptive significance may just be design flaws
most data testing comes from WEIRD societies and undergraduate students = hard to test universality
Gender-Neutral evolutionary theory
no fixed gender differences
more adaptive to be flexible in behaviours
some males are masculine dominant in certain situations then feminine dominant, therefore fixed mating strategies are not beneficial across these situations
= does lead to higher reproductive success
too new
also accounts for transgendered persons
Psychoanalytic theory
sex as one of key forces in human life
sex energy = libido death energy = thanatos = two major forces of motivation
Id, Ego, Superego
Id: basic part of the personality, present at birth, the reservoir of physic energy, operates on the pleasure principle, irrational
ego: develops a few years later, reality principle, tries to keep Id in line, realistic, rational interactions with others
superego: develops last as a child learns moral values, the consciousness, the values and ideals of society that we learn, operates on idealism, to inhibit the impulses of the id and to persuade the ego to strive for moral goals rather than just realistic ones
erogenous zones
an area sensitive to stimulation where libido energy is focused
Stages of psychosexual development
birth-1: oral stage, pleasure from sucking or stimulation of mouth and lips, put anything in thier mouth
2: anal stage, elimination of feces
3-5/6: phallic stage, pleasure from genitals, development of the oedipus complex
adolescence: latency stage, sexual urges are repressed, resolution of oedipus complex
puberty: genital stage, all oral, anal, and genital urges come together for biological reproduction
Oedipus complex
hostility towards father as a competing male for the mother, fear the father will castrate son in retaliation, this anxiety becomes so great he instead identifies with his father - key factor of personality development
female oedipus complex: (electra complex) girls love for her mother, realizes she does not have a penis and suffers from penis envy, resolved when she identifies with her mother and switches zones from clitoris to vagina to have kids
