Introduction to Psychology (Saylor Academy PSYCH101)

Saylor Academy's course suits anyone who wants something to show for the effort without paying for it: it comes with a free certificate. It introduces the fundamental principles of psychology and the major subjects of inquiry, with units arranged around broad areas of research such as emotion, development, memory and psychopathology. Saylor estimates about 46 hours of study, more than twice the Coursera courses. That makes it a sensible second step once a short taster has convinced you to keep going, and a good alternative for readers who would rather work through units at their own speed than follow a lecturer.
