For reading, start with Thinking, Fast and Slow by Daniel Kahneman, The Man Who Mistook His Wife for a Hat by Oliver Sacks, Phantoms in the Brain by V. S. Ramachandran and Sandra Blakeslee.
Then broaden into How the Mind Works by Steven Pinker, The Psychology Book by DK Publishing so you can compare cognitive, clinical, neuroscience and overview approaches.
For lecture-style video, use YaleCourses, MIT OpenCourseWare, CrashCourse, Stanford, The Royal Institution; the aim is to build concepts before reducing them to personal-statement claims.
For podcasts, Speaking of Psychology, Brain Science, The Psychology Podcast, Nature Podcast can help you hear how psychologists and scientists talk about evidence, uncertainty and application.
For structured study, Introduction to Psychology, 9.00SC Introduction to Psychology, Starting with psychology, Introduction to Psychology give a route through the subject that is more disciplined than isolated videos.
Keep a short evidence log: claim, method, sample, result, limitation and one open question the evidence does not yet answer.
