Cognitive science normally takes the individual agent as its unit of analysis. In many human endeavors, however, the outcomes of interest are not determined entirely by the information processing properties of individuals. Nor can they be inferred from the properties of the individual agents, alone, no matter how detailed the knowledge of the properties of(More)
We are quickly passing through the historical moment when people work in front of a single computer, dominated by a small CRT and focused on tasks involving only local information. Networked computers are becoming ubiquitous and are playing increasingly significant roles in our lives and in the basic infrastructures of science, business, and social(More)

Reasoning processes require stable representations of constraints. There are two principal ways to achieve stability in conceptual models. First, the conceptual models that anthropologists call cultural models achieve representational stability via a combination of intrapersonal and interpersonal processes. Second, the association of conceptual structure(More)
This paper reports a set of computer simulations that demonstrate a form of adaptation that we believe to be characteristic of human intelligence. One of the central problems faced by biological and artificial systems is the development and maintenance of coordination between structure inside the system and structure outside the system. That is, the(More)
Cognitive ecology is the study of cognitive phenomena in context. In particular, it points to the web of mutual dependence among the elements of a cognitive ecosystem. At least three fields were taking a deeply ecological approach to cognition 30 years ago: Gibson's ecological psychology, Bateson's ecology of mind, and Soviet cultural-historical activity(More)
Like all other branches of cognitive science, distributed cognition seeks to understand the organization of cognitive systems. Like most of cognitive science, it takes cognitive processes to be those that are involved in memory, decision making, inference, reasoning, learning, and so on. Also following mainstream cognitive science, it characterizes(More)
We present ChronoViz, a system to aid annotation, visualization, navigation, and analysis of multimodal time-coded data. Exploiting interactive paper technology, ChronoViz also integrates researcher's paper notes into the composite data set. Researchers can navigate data in multiple ways, taking advantage of synchronized visualizations and annotations. The(More)
