Charles W. Eriksen

Charles W. Eriksen (February 4, 1923 – February 16, 2018) was a pioneering American psychologist renowned for his extensive research in visual attention and cognitive control. His most notable contribution is the development of the Eriksen Flanker Task, a widely used experimental paradigm in cognitive psychology that assesses an individual's ability to manage conflicting information and maintain focus on relevant stimuli.

🧠 Early Life and Education

Born in Omaha, Nebraska, Eriksen pursued his undergraduate studies at the University of Nebraska. He later earned his Ph.D. in clinical psychology from Stanford University. His academic journey laid the foundation for a career dedicated to exploring the intricacies of human cognition and attention.

🔬 Contributions to Cognitive Psychology

In collaboration with his wife, Barbara A. Eriksen, Charles W. Eriksen introduced the Eriksen Flanker Task in 1974. This task measures an individual's selective attention and the ability to suppress responses to irrelevant stimuli. Participants are required to focus on a central target stimulus while ignoring flanking stimuli that may be congruent or incongruent with the target. The task assesses how quickly and accurately individuals can respond to the target stimulus amidst potential distractions.

The Flanker Task has become a standard tool in cognitive psychology and neuroscience for studying attention, response inhibition, and the effects of interference on cognitive processing. It has been applied in various research areas, including developmental studies, clinical assessments, and investigations into neurological conditions.

🏛️ Academic Career and Editorial Work

Eriksen held academic positions at several institutions, including Johns Hopkins University and the University of Illinois at Urbana-Champaign. He was deeply involved in research on visual perception and attention. From 1971 to 1993, he served as the editor of Perception & Psychophysics, a leading journal in the field, where he influenced the direction of research in experimental psychology.
