Event boundary judgements depend on schema activation
and subsequently affect encoding of perceptual action sequences.
Past work has either focused on process level descriptions (Neisser)
without computational implications or on knowledge structure
level descriptions (Schank's "scripts") without also providing
process level descriptions at a computational level.
The present work combines both process level descriptions and
learned knowledge structures in a simple recurrent connectionist
network.

The recurrent connectionist network is used to model human's
event parsing judgements of two kinds of video-taped
event sequences.  The network can accomodate the complex
event boundary judgement time-series and makes predictions
about the basis of how schemata are activated, what role
they play during encoding and how they develop during learning.
