It closes on one question: if our wiring is set before we can choose our environment, how much of you is actually you? #Psychology #DevelopmentalPsychology #ChildDevelopment #Trauma #AttachmentTheory #Neuroscience #PrenatalStress #CharacterArmor #Freud #Vygotsky #MaryAinsworth #CulturalPsychology #Adolescence #TransgenderIdentity #MentalHealth #PsychologyPodcast #PsychStudents

On this late-night study session of The Psychology Undergrad, we work through lifespan development from before conception to adulthood. We start with epigenetics and transgenerational trauma: how the Dutch Hunger Winter, colonization and the "haunted womb" leave biological marks that pass down through generations. Then we put the classic theories to the test: Erikson's psychosocial stages, Piaget's cognitive stages (mnemonic: Smart People Cook Food), Levinson's life structures (adulthood as levelling up in a video game), Bandura's triadic causation, and Gilligan's ethics of care as a response to Kohlberg. We look at where each one's "ruler" was marked wrong for women and marginalized groups. We also walk through two case studies, Carla and Ariana, rebuild Bronfenbrenner's ecological model as a smartphone (app, operating system, Wi-Fi), and cover Hays' ADDRESSING model and Hardy's privileged and subjugated tasks. Our closing question: if farming changed human development 11,000 years ago, what will digital life do seven generations from now?
