PSYC2800 treats gender and sexuality as legitimate, well-researched areas of psychological science, distinguishing evidence-based findings from both outdated assumptions and popular misconceptions in either direction.
Gender identity and development
PSYC2800 covers gender identity development research, distinguishing gender identity (one's internal sense of gender) from gender expression (how that identity is outwardly presented) and biological sex, and examines research on how gender identity typically develops and the psychological research on gender-diverse and transgender experiences.
Sexual orientation and human sexuality across the lifespan
The course covers research on sexual orientation development and the current scientific consensus on its likely biological and environmental contributing factors, alongside human sexuality's development across the lifespan — examining sexuality as a normal, healthy aspect of human development rather than a taboo topic to be avoided in psychological education.

Worked example: distinguishing gender identity, expression, and biological sex
- Biological sex: Physical/anatomical characteristics typically categorized as male, female, or intersex
- Gender identity: A person's internal, deeply felt sense of their own gender, which may or may not align with their biological sex
- Gender expression: How a person outwardly presents their gender through clothing, behavior, and other social cues
- Why the distinction matters: These three dimensions can vary independently — understanding them as separate constructs, rather than a single collapsed category, is foundational to accurate psychological research and clinical practice in this area

Frequently asked questions
Historically, these three dimensions were often collapsed into a single assumed category, but psychological and biological research has established that they can vary independently of one another — biological sex refers to physical and anatomical characteristics, gender identity refers to a person's internal, deeply felt sense of their own gender, and gender expression refers to how that identity is outwardly presented through behavior, clothing, and other social cues. PSYC2800 teaches this distinction because treating them as inseparable prevents accurate understanding of gender-diverse and transgender experiences, where gender identity doesn't align with the sex assigned at birth, and prevents accurate research and clinical practice around gender more broadly — recognizing these as distinct, independently-varying dimensions is now considered standard, evidence-based practice within psychological science, reflecting research findings rather than a purely political or ideological stance.
Current scientific research suggests that sexual orientation likely results from a complex interplay of genetic, hormonal, and environmental factors during development, rather than being a simple, single-cause phenomenon or, as was once incorrectly assumed, a straightforward choice or a result of a specific parenting style or life experience — twin studies show a genetic contribution, though not a simple single-gene determination, and research has not supported now-discredited theories attributing sexual orientation to particular family dynamics or a purely willful choice. PSYC2800 teaches this research because understanding sexual orientation as arising from this complex, multifactorial developmental process, rather than from now-discredited theories, is both scientifically accurate and has significant implications for reducing stigma and informing evidence-based, affirming approaches in psychological research, education, and clinical practice, replacing outdated assumptions that have not held up under rigorous scientific scrutiny.
