Alpha Bias = Are differences
Beta Bias = Bull****** there are no differences
Thats how I remember them,
I Thought Eriksons theory was Alpha because he suggested males achieve identity by their job whereas females achieve it by the type of man they marry.
Having no females and only males in the sample is Androcentric, not beta bias
The ones that I've learnt are:
Alpha:
Freuds Theory - Women have inferior morals due to underdeveloped superego
Socio-Biological Theory - Males look for youth and attractiveness in a partner whereas females look for wealth and status
Erikson - (as above)
Beta:
Stress Response - Selye suggested both men and women have a flight or fight response but later research suggests females "tend and befriend"
Hope tht helps
Good luck
