ACT-R workshop 2026 - Session on Music Cognition

This is the list of speakers for an ACT-R workshop session on music cognition I have organized. Music cognition is a particularly challenging domain area for the ACT-R cognitive architectures. The session will address issues related to the motor control of hands and fingers at the piano, models of figured bass and melodic improvisation, as well as modelling memory in relation to AI and humans in the world of music.

Bruno Emond (Independent researcher) Two Hands, Ten Fingers: Extending ACT-R's Motor Capabilities for Bimanual Piano Modelling.
Wolfgang Schoppek (University of Bayreuth) Further Forays into Music Psychology: ACT-R Learns to Improvise Figured Bass.
Panos Mavromatis (New York University, Steinhardt) Building an ACT-R Model of Melodic Improvisation from a Corpus-Driven Grammar.
Mark Orr (Institute for Human-Machine Cognition The Aesthetics of Declarative Memory.

Type checking on Common Lisp Object System slots (updated)

In September I posted some code to add type checking to CLOS class slots that does not seem to be handled by LispWorks. The code below is simpler and was designed to run without errors and warnings with Steel Bank Common Lisp (SBCL). As the compiler directives show, most of the code is to make  […]

Type checking on Common Lisp Object System slots

The Common Lisp standard specifies that "The consequences of attempting to store in a slot a value that does not satisfy the type of the slot are undefined.” CLHS: Macro DEFCLASS. However, type checking prevents making simple mistakes, makes code easier to understand, and ultimately leads to  […]
