About Me

I am primarily a learning psychologist, also interested in neural networks and cognitive control. Some of my specific research interests include human contingency learning, temporal contiguity, temporal learning, the Stroop effect, computational modelling, cognitive control, conflict monitoring and adaptation, attention, episodic memory, unconscious processes, learning goals, habits, music cognition, evaluative learning, stimulus-response binding, switch costs, human reasoning ability, logic, and bilingualism. I completed my B.A. with high honours in psychology and a minor in philosophy at the University of Saskatchewan in 2005, supervised by Jim Cheesman. I obtained my Master’s in 2007 and my Ph.D. in 2009 in cognitive psychology at the University of Waterloo, supervised by Derek Besner. I then worked as a postdoc at Ghent University with Jan De Houwer. I am currently a full professor of the Université de Bourgogne working in the Laboratoire d’Etude de l’Apprentissage et du Développement (LEAD). You can see my full CV here. Outside the office, I spend an embarrassing amount of time speedsolving twisty puzzles (mostly poorly). My current collection here.

Learning Psychology

My main program of research focuses on basic processes in human contingency learning, binding, and temporal learning. In this work, I answer questions such as whether contingency awareness is required for contingency learning, how fast learning occurs, and the role of goals on learning. More generally, I am interested in determining how experienced stimuli, responses, and temporal (timing) information are bound together into episodes (i.e., mental representations of events), and how this trial information is stored in and retrieved from episodic memory. Contingency learning, temporal learning, binding, etc. are proposed to be the incidental result of such memory processes.

Another side of this research program is exploring how the ability of participants to easily pick up on regularities (whether consciously or unconsciously) and use this information to maximize performance often produces confounds in experiments aimed at studying wholly-unrelated mental processes. Quite frequently, experimenters introduce unintentional regularities into the task structure of experiments (e.g., covariations between stimuli and responses or differences in task pace across conditions). Participants are extremely adept at picking up on such regularities (often implicitly) and exploiting them. My goal is to understand the automatic influences of this memory retrieval on behaviour.

Related to this line of research, I developed the Parallel Episodic Processing (PEP) computational model. For more information, see the Code tab.

Music Cognition

In recent work, I have been applying some of my work on basic learning and timing processes to early music learning. Globally, the idea is that to master certain musical skills, a lot of repetition is needed to automatize performance. Incidental learning is particularly efficient in learning rapidly. One key skill that we are aiming to improve is sightreading ability.

Music is typically written in standard notation. Standard notation represents various different types of information, such as the note pitches and timings. Note pitch (e.g., do, ré, mi; or C, D, E in the North American system) is represented by the vertical placement of the note on the musical staff. Sightreading is the ability to look at a musical staff and play the notes while reading. This is an important skill, but one that takes a while to master (e.g., several semesters of music training). Using incidental learning procedures, however, we have been able to show that learning to sightread can occur substantially faster.

Cognitive Control

One of my main programs of research focuses on the cognitive and attentional control literatures. For instance, I have conducted considerable research on the proportion congruent and congruency sequence (aka Gratton) effects. These two phenomena are typically interpreted in terms of conflict adaptation (or conflict monitoring). The conflict adaptation account proposes that when participants experience conflict between stimuli (e.g., between the distracting word “blue” and the target colour red in a Stroop task), they dynamically adjust attention away from the distracting word and/or toward the target colour. However, effects such as the proportion congruent and congruency sequence effects might also be explained by the learning of task regularities unrelated to conflict. In particular, I have investigated the role of episodic memory biases (e.g., feature repetition, contingency learning, and temporal learning effects) that represent confounds in these tasks. Controlling for such confounds seems to eliminate the effects, suggesting that the supposed conflict adaptation is illusory.

I have recently expanded this research out to switch costs, that is, the finding that there is a performance cost when switching from one task to another. Switch effects, too, are generally interpretted in terms of higher-order control processes, such as task set reconfiguration or task set inertia. However, some of my recent work has demonstrated that feature integration biases explain the bulk of the switch cost. As such, higher-order cognitive control processes might play a substantially smaller role in switch costs than previously assumed.

Related to this line of research, I developed the Parallel Episodic Processing (PEP) computational model. For more information, see the Code tab.

Conflict Tasks

In one line of research, I explore basic processes in conflict tasks. This work often uses the colour-word Stroop task or conceptually similar tasks. In the Stroop task, participants identify the colour of a colour word. This creates conflict when the word and colour are incongruent (e.g., the word “orange” printed in blue) relative to when they are congruent (e.g., “orange” printed in orange). This indicates a partial failure of selective attention, as the word influences colour identification even though participants are trying to ignore it. My research in this domain explores what cognitive mechanisms are responsible for this conflict effect. For instance, is this congruency effect due to a conflict in meaning between the word or colour (semantic or stimulus conflict) or to a conflict in the responses that that are suggested by the two (response conflict)?

In more recent years, we have been using the same task to better understand bilingual memory. For instance, do early language learners learn new words in a foreign language as lexical translations of the corresponding word in their first language (e.g., chien = dog) or are foreign language words strongly connected to semantic knowledge?

Data Merging

I programmed a free-to-use Java program for concatenating together CSV data files (e.g., created by programs like PsychoPy). The program also resorts columns if the program does not order the columns in the same way for all participants. For more information, see this page.

Neural Networks

I have done a lot of work with neural networks, particularly with the Parallel Episodic Processing (PEP) model that I programmed. The PEP model learns via the storage and retrieval of episodic memories. At a conceptual level, it is similar to other episodic (or instance or exemplar) models (e.g., GCM, MINERVA 2, etc.), but the PEP model is designed for simulating performance in a variety of different tasks in which reaction times (in addition to error rates) are the typical dependent variable of interest, rather than for simulating memory effects proper (e.g., item recall or recognition).

On each trial, the model stores a memory of the stimuli that were presented, the response that was made, and the time it took to respond. On subsequent trials, memories are retrieved to the extent that they are similar to the input (e.g., the same stimulus). So far, the published version of the model can engage in both contingency learning (i.e., learning what to respond) and temporal learning (i.e., learning when to respond). These mechanisms were shown to account for practice curves, decreasing Stroop effects across blocks, contingency learning effects and acquisition curves, stimulus-response binding effects, mixing costs, and word reading and colour naming asymmetries. In addition, the model also successfully simulates several findings in the cognitive control literature, including item-specific proportion congruent effects, list-level proportion congruent effects, congruency sequence effects, asymmetric list shifting effects, and context-specific proportion congruent effects. Critically, the basic learning mechanisms in the model produce these effects without appealing to the notion of conflict adaptation. More recently, we have been applying the model to instruction following and task switching.
