Bottlenecks: Aligning UX Design with User Psychology, written by David C. Evans and technically reviewed by Dr. Peter Meyers, informs entrepreneurs, designers, developers, publishers, and advertisers of the relationship between user psychology and UX design, stating that innovations must survive the psychological bottlenecks of attention, perception, memory, disposition, motivation and social-influence if they are to proliferate (p. xiii). Bottlenecks aims for readers to understand the psychological considerations that one must make when instituting digital memes, which are digital ideas, inventions, or particles of culture whose diffusion through a population can be observed (p. xiv). Overall, Bottlenecks is an excellent resource for anyone in a marketing, research and development, or design role at a company that produces digital memes.
