This section covers my coursework for PSY225, focusing on how psychological principles directly govern user experience. From understanding pre-attentive attention and dopamine-driven habit loops to unpacking intrinsic and extrinsic motivators, these projects audit the boundaries of human working memory and perception. Grounded in both theory and practical UX application, these briefs investigate how behavioural models and neuropsychology inform usability, helping designers respect human attention rather than overwhelm it.
