Document Summary

Few significant differences: even these differences are very small. Factors that can influence the size of gender differences (confounds) Gender differences are largest when behavior is measured in terms of self-report. Gender differences are largest when other people are present. Gender differences are largest when gender is prominent and other shared roles are minimized. Gender differences are largest when the behavior requires specific gender-related skills. Longitudinal studies: a study preformed over a period of time with the same subjects, weaknesses include sometimes subjects drop out (mortality), expensive, time. It is strong because it you are using the same subjects consuming. General helpfulness = helping someone overcome some difficulty: stereotype : females are more helpful than males. However there is only a 0. 13 effect size in a meta analysis of 182 studies. Men more likely to help if helping would be dangerous (ie. picking up a hitchhiker) When specific skills/knowledge is needed (ie. changing a tire)
