"Excellent book! It covers the field to some of its remotest corners ... In my opinion the chapters are well organized, very well written, very accessible, and very informative. Key concepts are very well explained. There are detailed discussions of research designs, and the effects these can have on research outcomes, statistical methods, and the meaning of the outcomes. This is the perfect textbook for undergraduate and graduate students across the world. The book offers a wide overview of the field, but it is clearly geared towards students of psychology." - Jean-Marc Dewaele, Birkbeck, University of London, School of Languages, Linguistics, & Culture, UK
