This book provides a complete introduction into basic theoretical problems in understanding the planning and control of human goal-directed actions and it covers important milestones in the empirical investigation of these issues. The book is presenting this topic in an attractive way: by focusing on major theoretical themes and their empirical implications, the authors are really "telling a story" that connects the different chapters and issues to a coherent whole. The book targets advanced undergraduates, graduates, but also PhD students in cognitive psychology and related areas, such as the cognitive neurosciences, developmental and social psychology.
