Vision: A Computational Investigation into the Human Representation and Processing of Visual Information
-
David Marr's posthumously published Vision (1982) influenced a generation of brain and cognitive scientists, inspiring many to enter the field. In Vision, Marr describes a general framework for understanding visual perception and touches on broader questions about how the brain and its functions can be studied and understood. Researchers from a range of brain and cognitive sciences have long valued Marr's creativity, intellectual power, and ability to integrate insights and data from neuroscience, psychology, and computation. In Marr's framework, the process of vision constructs a set of representations, starting from a description of the input image and culminating with a description of three-dimensional objects in the surrounding environment. A central theme, and one that has had far-reaching influence in both neuroscience and cognitive science, is the notion of different levels of analysis--in Marr's framework, the computational level, the algorithmic level, and the hardware implementation level. Now, thirty years later, the main problems that occupied Marr remain fundamental open problems in the study of perception. Vision provides inspiration for the continuing efforts to integrate knowledge from cognition and computation to understand vision and the brain.

Vygotsky and the Social Formation of Mind
-
In a book of intellectual breadth, James Wertsch not only offers a synthesis and critique of all Vygotsky's major ideas, but also presents a program for using Vygotskian theory as a guide to contemporary research in the social sciences and humanities. He draws extensively on all Vygotsky's works, both in Russian and in English, as well as on his own studies in the Soviet Union with colleagues and students of Vygotsky. Vygotsky's writings are an enormously rich source of ideas for those who seek an account of the mind as it relates to the social and physical world. Wertsch explores three central themes that run through Vygotsky's work: his insistence on using genetic, or developmental, analysis; his claim that higher mental functioning in the individual has social origins; and his beliefs about the role of tools and signs in human social and psychological activity Wertsch demonstrates how the notion of semiotic mediation is essential to understanding Vygotsky's unique contribution to the study of human consciousness. In the last four chapters Wertsch extends Vygotsky's claims in light of recent research in linguistics, semiotics, and literary theory. The focus on semiotic phenomena, especially human language, enables him to integrate findings from the wide variety of disciplines with which Vygotsky was concerned Wertsch shows how Vygotsky's approach provides a principled way to link the various strands of human science that seem more isolated than ever today.

What action did student researchers take?
-
This research booklet summarised the actions taken by Ultraversity students graduating in 2006. It showed how their focus was on vital and relevant issues in their workplace, despite the high level of self-direction and freedom offered.
