We are doing basic research on software agents that can live in virtual
environments and which can help users find resource materials from
large libraries, such as the UC system library or the Library of Congress.
We videotape and analyze the interactions between research librarians
and students searching for materials, and explore different resources
which will facilitate better interviews and more effective use of
electronic catalogs. More |

For the past several years we have been constructing computational
models of how people improve as they play Tetris. Recently we have
extended this study to a more age distributed population. We are particularly
interested in determining if the learning trajectory of elderly subjects
parallels younger subjects or if there are biases in the way they
acquire Tetris skills that reflects differences in the relative robustness
of different cognitive systems. More |

The animation project is concerned with determining for which sorts
of data relations and for which sorts of data analytical tasks animation
is an effective and an expressive means of display. Towards an understanding
of these issues, an experiment by Kaiser, Proffitt, Whelan, and Hecht
is being replicated and extended. More |

We are currently running a series of experiments in which we study
how people select different strategies for counting various arrangements
of coins. We compare speed and accuracy as different levels of interactivity
are allowed, such as permitting subjects to use their hands to point,
count, move the coins, etc. More |

A further topic of interest in the lab is how people come to agree
on a common action when they have competing interests. Are there general
cognitive biases in the way we reason, classify, and build recursive
expectations of each other that push us toward stable agreements?
How do we frame our negotiations? Such questions are important in
understanding how people structure their environment when there are
other agents they share their workplace with. More |
