When a study reports a sex difference in mental rotation, what else do you need before you treat that difference as biology?
The operational definition, the effect size, and whether culture and training were measured. Sex in the intro texts is biological status. Gender is the social and personal organization of roles and identities around sex (Myers & DeWall, 2021; Spielman et al., 2020). A mean difference between groups named male and female does not, by itself, tell you which of those you measured.
If a social role changes what people practice, what happens to a skill that looks “natural”?
The skill can move. Figure 7.1 separates sex, gender, and culture as different things a paper might be about, each with a different operational path. Later social-psychology and development courses will argue the mechanisms. This survey only has to stop a reader from treating a group mean as a finished biological story.
| Term | What the paper is about | Example operational path |
|---|---|---|
| sex | Biological status | Chromosomes, gonads, or anatomy as recorded |
| gender | Roles, identity, social meaning | Self-report of identity; ratings of role norms |
| culture | Shared practices and institutions | Nation, language community, or measured practices |
