How are social behaviors initiated, sustained, disrupted, and resumed? What are the cognitive bases of goals, and how are goals and actions affected by emotions? Putting an end to the traditional, and unproductive, juxtaposition of motivation and cognition, this book relates these domains to shed new light on the control of goal-directed action. Bringing together renowned social and motivational psychologists, it presents concise formulations of complete research programs that effectively map the territory, provide new findings, and suggest innovative ideas for future research.
