Brendan’s Masters’ thesis:

Click to read thesis: ‘Clarifying Metacognition’

This thesis presents a novel method of modelling metacognition computationally.

Metacognition is  described as cognition acting on itself, and can improve memory, reasoning, emotional regulation, and motor skills. How it does this remains unclear. The two major barriers are: its high abstraction and disputed terminology.

To overcome these barriers this thesis employs a computational cognitive architecture to define the base units of cognition, and how they come to act on themselves. Well-defined computational units are built upon to form increasing complex metacognitive processes. These computational forms of metacognition are then connected to the research literature and built into working models in ACT-R.

The intention of this thesis is to help clarify the nature of metacognition and its underlying mechanisms.

Spring Conference

The Spring Conference was a great success! It was a fantastic experience helping to organize the event, along with presenting my work in a 15 minute lecture to faculty and colleagues.

Thesis Proposal is Go!

Thesis prospectus approved!  

Metacognitive Modeling now has the green light.

I propose to synthesize the literature on metacognition, and connect it to the cognitive ‘Common Model’ : 


Really, metacognition is just “thinking about thinking.” It’s part of daily life, when we ask ourselves “Did I forget anything? Did I understand that?” Have you ever noticed a thought or emotion? That’s meta. It’s ordinary.

Metacognition also allows for higher thinking. It’s the number one predictor of learning and an indicator of business success. Hey, science itself is metacognitive. Directing our thoughts is how we uncover the secrets of the universe.

Now we’re trying to understand how. How does the mind understand itself? How can we benefit?

The problem is that it’s abstract. Metacognition remains a lonely mountain peak shrouded in fog. Yet we can shine a light onto it with cognitive modeling. This is how I aim to help research on metacognition, in a way not yet done – metacognitive modeling.

HED Research Program + Blog

(By Jen Schellinck)

As mentioned in So Many Summer Projects, Ken and I spent the summer getting the Human Exploitation Dynamics (HED) Research Program off the ground. Things have been going well and we had our first user-test of the simulated environment mid-August.

To avoid cluttering up the Cognitive Modeling Lab blog with too many simulation mechanics related posts, I’ll direct folks to the HED Research Program blog if you would like more technical details about what’s happening with that project, but I’ll also cross-post relevant articles here from time to time, in case people want to follow along.

Thank You







Another update, I am honoured to be receiving the Institute of Cognitive Science departmental Teaching Assistant Excellence Award.

It’s been an incredibly rewarding experience helping so many enthusiastic students. Thank you to all my supportive and dedicated colleagues!

A Thesis for Brendan







After an unusually warm summer full of more work than play, I have finally settled on my thesis topic (cue trumpets). This thesis involves a life long interest of mine – metacognition.

My thesis will involve modelling metacognition within the cognitive architecture ACT-R (as developed by Robert L. West). The thesis will discuss the philosophical properties of metacognition using the cognitive architecture.  This will make for a broad and yet strong foundation for the topic, well affirmed from my discussions with Dr. West.

The applications of a metacognitive model holds many exciting possibilities, both for human and artificial agents. While this topic extends far beyond my humble thesis, I intend to help lay some of the necessary philosophical groundwork. After all, a blueprint is needed before building in stone – or silicon, anyway.

So Many Summer Projects

(By Jen Schellinck)

Summer project work is in full swing in the cognitive modelling lab. In brief…

  • Kate is working to submit multiple abstracts and papers on Rachel, her A.I. model of human cognition,
  • David is updating and rejuvenating his wikimergic/wikisilo site and working on his book on open vs closed thought forms,
  • Brendan is putting the finishing touches on his paper on cognitive history,
  • Phoebe is undertaking the massive task of bringing us into the modern world of citation and paper management and taking psych courses,
  • Liz is beta-testing a new cognitive task app that will be used to collect data for upcoming experiments,
  • Chad submitted a conference paper,
  • Ken and I are rocketing along in developing the Islands game, which will be used to study exploitation dynamics,
  • Emily is gearing up to enter the world of cognitive science (via the Master’s program),
  • Adam is preparing to plow through a massive reading list of articles,
  • AND everyone else is so busy they didn’t have a chance to update us this week!
  • So much for a quiet summer!
