The Interpretation of Biological Motion
(1980-12-01)

Towards a Better Definition of Transactions
(1980-12-01)
This paper builds on a technical report written by Carl Hewitt and Henry Baker called "Actors and Continuous Functionals". What is called a "goal-oriented activity" in that paper will be referred to in this paper as a ...

Destructive Reordering of CDR-Coded Lists
(1980-08-01)
Linked list structures can be compactly represented by encoding the CDR ("next") pointer in a two-bit field and linearizing list structures as much as possible. This "CDR-coding" technique can save up to 50% on storage ...
Against Direct Perception
(1980-03-01)
Central to contemporary cognitive science is the notion that mental processes involve computations defined over internal representations. This notion stands in sharp contrast with another prevailing view ??e direct ...
A Session with TINKER: Interleaving Program Testing with Program Design
(1980-09-01)
Tinker is an experimental interactive programming system which integrates program testing with program design. New procedures are created by working out the steps of the procedure in concrete situations. Tinker displays ...
One Child's Learning: Introducing Writing with a Computer
(1980-03-01)
