These essays by leading theorists and researchers in sociocultural, cognitive, developmental, and educational psychology honor the memory of Sylvia Scribner, whose work is recognized by each of the authors as seminal to their own thinking. The themes include the relationship between history and culture, the importance of context to thinking, the place of literacy in human activity and thought, and cognition in school and in the workplace. The volume presents applications of activity theory to fundamental issues in human behavior at work, in school, and in problem solving situations, and it analyzes historical-societal processes in science and culture. Scribner's conviction that science holds a responsibility to human welfare and understanding is carried on in these chapters. Sociocultural Psychology is crucial reading for researchers and graduate students in sociocultural, cognitive, developmental, and educational psychology.
