This book provides an introduction to motivational research on the basis of everyday phenomena and self-awareness. The discussion leads from explanations based on instinct and drive theory through the analysis of situational stimuli towards classic motivational psychology. Aspects drawn from current research that are discussed include volitional research, risk motivation and pleasurable absorption in activity (flow experience). The concept of motivational competence is then drawn out. The final chapter deals with ways of measuring motivation (motivational diagnosis). Using selected examples, the authors succeed in making typical forms of behaviour and model conceptions comprehensible. For this ninth edition, the content has been updated and educational aspects have been revised.
