PSYB30H3 Chapter Notes - Chapter 11: American Majority, Meta-Analysis, Mental Rotation
Document Summary
Men are better than women when it comes to spatial ability: spatial reasoning where participants have to mentally rotate an object. In one experiment, women who trained on an action game (not a puzzle game) caught up to the spatial ability level of the average man without the special training (in the action or puzzle game) Beliefs about personality similarities and differences between men and. Women are believed to be more concerned with nurturing whereas men are more concerned with actions and accomplishments. Effect size tells us the size of that difference: e. g. The amount of tomatoes or lime juice a salsa has will affect its overall taste. In a meta-analysis, researchers combine the individual results of different experiments to calculate an estimate of how large an effect is across many different participants, samples, experimenters, methods & measures. Effect size is estimated using the formula d: d=mm-mf / s. Close to 0 d= not much of a difference.
