This session will provide an in-depth look at human perception and cognition, and its implications for interactive and visual design. The human brain is purely treated as an information processing machine, and we will teach the audience its attributes, its advantages, its limitations, and generally how to hack it. While the content will provide a deep review of recent cognitive science research, everything presented will also be grounded in example design work taken from a range of Google applications and platforms. Specific topics will include: edge detection, gestalt laws of grouping, peripheral vision, geons and object recognition, facial recognition, color deficiencies, change blindness, flow, attention, cognitive load balancing, and the perception of time.

via Cognitive Science and Design — Google I/O 2013.

From this year's Google I/O conference. Well worth the 35 minutes.
