Dr. Ian G. Mackenzie serves as a Wissenschaftlicher Mitarbeiter in the Department of Psychology at Eberhard Karls University of Tübingen, part of the Faculty of Science. Affiliated with the Biological Psychology research group, he is based at Schleichstraße 4, Room 4.427. Mackenzie holds a Ph.D. and contributes to the university's Collaborative Research Centre SFB Common Ground. He is also an academic member of the Studienkommission responsible for Bachelor and Master programs in Psychology and School Psychology. His presence in Tübingen publications dates back to at least 2011, indicating a sustained career in experimental Psychology.
Mackenzie's research centers on cognitive control mechanisms within conflict tasks, including the Simon task, Eriksen flanker task, and Stroop task. He applies the Diffusion Model for Conflict tasks (DMC) to investigate proactive control adaptation, temporal cueing of conflict, distractor suppression, target processing, congruency sequence effects, and visual eccentricity influences. Additional interests encompass distributional analyses, model-based parameter estimation, and introspection regarding choice and time estimation. Notable publications include "Temporal cueing of conflict reduces congruency effects in the Eriksen flanker and Simon tasks" (2026); "How Visual Eccentricity Shapes Conflict Via Target and Distractor Processing in the Simon Task" (Psychonomic Bulletin & Review, 2025); "No Congruency Sequence Effect Across Simon and Eriksen Tasks with Aligned Temporal Processing Dynamics: Evidence for Domain-Specific over Domain-General Cognitive Control" (Memory & Cognition, 2025); "Proactive Control Adaptation in Stroop Tasks Reflects Adjustments in the Strength of Distractor Suppression" (Journal of Experimental Psychology: Learning, Memory, and Cognition, 2025); "Introspection about Forced and Free Choice: Accurate Subjective Time Estimation for Externally as well as Self-Determined Actions" with Daniel Bratzke (Consciousness and Cognition, 2024); "The role of temporal order of relevant and irrelevant dimensions in the Simon task" (Psychological Research, 2022); and "Applying the diffusion model for conflict tasks" with Valentin Koob et al. (Psychonomic Bulletin & Review, 2023). These works advance experimental methodologies in cognitive Psychology.
