Human behaviour—both complex and simple—is such a fascinating subject for study and research, and therefore, psychology as a subject is of tremendous importance to the students and the researchers. This accessible and student-friendly text in its second edition, shows the ‘what,’ ‘why’ and ‘how’ of human behaviour patterns. The text emphasizes controlled and systematic studies to explain such behavioural aspects as sensing, perceiving, modifications of human behaviour, memorizing, the recollection of past events, and affecting processes. The text is interspersed with many examples to illustrate the concepts discussed. The concepts are well-supported with experimental as well as observational facts. What’s more, the book acquaints the reader with the recent advances in the field of psychology.
