Gyno centrism means being centred on or dominated by females e.g. Moscovici minority influence and Ainsworth’s Strange Situation
Moscovici used all female pp's but assumed findings generalised to both genders as did Ainsworth so suffer from gynocentric,beta bias
If focusing on female perspective leads to lack of validity or reliability, it has gynocentric bias
can lead to invalid conclusions or alpha bias e.g. Bowlby's attachment on women (mothers biologically programmed to form unique bond with children, suggesting babies attachments to mothers most important)
leads to alpha bias (women more important in childcare, no evidence), governments and court cases prioritise mothers in deciding upbringing of children
much less of a difference between men and women than Bowlby suggested so criticized for gynocentric alpha bias
Attachment research has historically been gynocentric.
