Welcome to the Pelli lab
How does the brain recognize objects, like letters,
words, and faces? We've shown that the first step is independent detection
of simple features by channels (PDF).
But how do we put those features together? We've discovered that crowding
is the failure of this binding, when too many features are included (HTML).
This insight has enabled fast progress on old problems: Faces are recognized
like words (HTML); Crowding
determines reading rate (PDF).
We are currently using a new feature-counting technique to analyze the
feature-integration process underlying object recognition and reading.
Our approach is mostly psychophysical. We measure thresholds on human
observers. We are gearing up to do more brain imaging of the object recognition
process. The pace is fast. Our experiments are simple. Our software is
flexible. More often than not, we answer the question in a week. Many
of these questions arise at the weekly lab meeting, where everyone participates
in a free-for-all discussion of each person's project. We welcome visitors.
