What is the difference between alpha and beta bias?
Alpha - exaggerates differences
Beta - Minimizes or ignores differences
Explain an example of alpha bias
Freud's Research:
psychoanalysis - viewed femininity as failed masculinity
argued women were jealous of men who experience the Odipeous complex
Women = morally inferior because they have weaker identification with their mothers + since superego develops with odipeousconflict.
Explain an example of beta bias
Biological research :
Research into fight or flight response
used male animals because of too much variation in hormone levels in females (difficulties)
assumed all male results would apply to females too
Shelley Taylor et al challenged universal assumption - evidence females = tend-and-befriend response to stress - adaptive to ensure survival of offspring
ignored possible difference - didn't fully understand stress responses
What is universality? Give an example
theories that apply to all people, regardless of gender or culture
Example : attachment - assumed to be same for all regardless of culture - secure attachment universal/common attachment type
What is androcentrism? Give an example.
male-centred
'normal' behaviour judged by male standards
Example : females often judged as inferior
Kohlberg's study of moral development - females judged as inferior and less moral
What study provides an example of both alpha and beta bias? Explain how.
Kohlberg's theory of moral development:
suggested that moral decisions we make are based on an ethic of justice.
Theory based on research with boys and men
asked to describe what behaviour would be right in a given situation (related to fairness)
Beta bias : assumed it would be thesame for all people.
Kohlberg then tested women - found they were lessmorallydeveloped than men
Alpha bias : exaggerated the differences between men and women.
How is Milgram's study an example of gender bias?
Beta bias : Ignores possible differences between men and women since all participants were men, it is possible that women will respond differently to the situation and may be more or less obedient.Generalizes results to all individuals and assumes women would show thesame results.
What are the main evaluation points using gender bias?
Beta biases may be a strength but also a limitation of research
2. androcentrism can be avoided by taking a feminist perspective
3. Psychological theories are based on gender-bias research using biased methods
Evaluation of gender bias : Androcentrism can be avoided
feminist psychology agrees there are real biologically basedsex differences BUT socially determined stereotypes -> perceived differences
before social change, must revise 'facts' about gender that perpetuate beliefs about women.
one way to redress the balance = use evidence that women may be inferior to provide women with support.
example : Eagly (1978) women may = less effective leaders BUT should be used to develop more suitable training programmes.
Evaluation of gender bias : beta biases may be a strength, but also a limitation.
Hare-Mustin + Marecek = arguing for equality between men + women draws attention away from women's differences in power.
seemingly neutral actions = benefit the more powerful group
e.g equal parental leave ignores biological demands of pregnancy, childbirth, and breastfeeding -> disadvantaging women
suggests we should avoid beta biases to ensure significant differences are taken account of
Evaluation of gender bias : Psychological theories + studies are gender biased because methods are biased.
example : Rosenthal (1966) found maleexperimenters = more pleasant, friendly + encouraging to femaleparticipants.
male participants therefore seemed to perform less well on tasks
furthermore, feminists argue lab experiments = disadvantage women because findings in controlled environment won't replicate experiences of women outside these settings
e.g Eagly + Johnson (1990) noted studies in real settings found men + women = judged more similar in styles of leadership than in labs.
