Introduction to Psychology — Unit 1: Introduction

Unit 1: Introduction

Scintillating grid: a white grid pattern on a black background, with the illusion of dark dots appearing at the intersections of the white lines.
The Hermann-grid illusion shown on the original unit page — one of the lecture’s visual demonstrations. The original page carried this image with a good caption and alt text; the remediated slide deck adds a long description (slides.html).

This session is an introduction to the subject of psychology: the scientific study of how we think, feel and act. The lecture features some fascinating examples and fun demonstrations on topics like optical illusions, limits of visual attention, the power of suggestion in memories, and the relationship between how we feel and how we act.

Keywords: perception, optical illusion, visual memory, visual attention, listening, automaticity, prediction, thinking, feeling, acting.
