Eriksen Flanker Task: Measuring Attention and Cognitive Control
Attention is a key component of our cognitive processes. It enables us to stay focused on specific tasks and maintain concentration over extended periods. One of the most popular and effective methods for assessing these abilities is the Eriksen Flanker Task.
Initially, visual search tasks were often used to gauge attention levels. However, these methods had several shortcomings, such as difficulty in distinguishing distractibility from the main outcome. The Eriksen Flanker Task addresses this issue by creating conditions in which distracting elements are an integral part of the task that must be ignored to succeed.
At its core, the Eriksen Flanker Task evaluates attention, selectivity, and cognitive control. It involves performing a series of actions that require high accuracy and minimal delays. For example, you might be asked to identify the direction of a central arrow among distracting arrows pointing in other directions or to determine the color of a central object amid other distracting color signals. Imagine seeing a sequence of arrows like this: “→→←→→”. Your job would be to identify the direction of the central arrow, which necessitates ignoring the surrounding distractions.
Interestingly, the Flanker Task is not the only method for assessing attention and cognitive control. The Stroop Task, where the color of a word may not match its meaning, and the n-back tasks, which evaluate working memory through sequences of numbers or letters, are also commonly used. However, the Eriksen Flanker Task remains one of the most widely recognized and effective due to its precision and efficacy.
By taking on Eriksen’s flanker task, you’ll gain precise insights into your cognitive abilities. Plus, you’ll have a clearer understanding of how well you manage attention control and maintain focus during extended, challenging tasks.
The Flanker Task of Charles Eriksen and Its Significance
First proposed in 1974, Charles Eriksen’s flanker task has become a cornerstone in studies focused on diagnosing attention under the influence of distractors. Charles Eriksen, a distinguished scientist and one of the pioneers in the theory of visual analysis, made invaluable contributions to our understanding of how the brain processes visual information. His experiments often involved alphabetic characters, where participants were required to identify a specific letter among similar symbols, significantly increasing the task’s complexity.
A key characteristic of human attention is the ability to focus on a single object, even when there is limited space between similar objects. Eriksen tested this hypothesis repeatedly, and in 1979, alongside his colleagues, he delved deeper into the specifics of visual tests. For example, in one experiment, participants needed to identify a target letter amidst distracting symbols, which revealed how distractors affect reaction speed and accuracy.

Eriksen proposed the continuous flow model of perception, suggesting that the brain processes different aspects of stimuli simultaneously, accumulating information over time to form a final response. This model has become fundamental for numerous studies and developments in cognitive psychology and neurobiology.
Eriksen’s observations and discoveries laid the groundwork for the creation of modern games and training programs aimed at enhancing cognitive abilities. An example of such programs is the online “Neurobics,” which helps train attention, memory, and thinking in an interactive and engaging manner. These games often use principles derived from the flanker task, giving users the opportunity to improve their cognitive skills through a series of entertaining tasks and puzzles.
Flanker Task and Logical Thinking: Testing Your Attention and Analytical Skills
The flanker task is a fascinating cognitive exercise designed to gauge how quickly and accurately a person processes visual information. The core idea is to evaluate how well the eyes and brain can simultaneously fixate on and recognize multiple similar objects. Participants must analyze seven elements, with the central one being key, and determine its direction or orientation.
Stimuli in the flanker task can be either congruent or incongruent. In congruent stimuli, the goals of the central element and the flankers align; for example, all the arrows pointing in the same direction: → → → → → → →. Here, all arrows point to the right, making the task easier. However, incongruent stimuli pose a true challenge to logical thinking. In this case, the central element points in the opposite direction of the flankers, like this: → → ← → →. This requires additional brainpower to determine the correct response.
Flankers can include more than just arrows; they might also be graphical objects such as colored spots, numbers, or even words. Picture a row of colored spots where all but the central one are the same color. The task would be to identify, for example, the brightest color while ignoring the less bright surroundings.
The ability to successfully tackle the flanker task heavily relies on active engagement of logical thinking. When logical reasoning is engaged, the brain meticulously analyzes all elements, considering even the tiniest details to arrive at the correct answer. Conversely, if logical thinking isn’t activated, the brain might overlook discrepancies or connections between the task elements and the depicted objects, leading to incorrect outcomes.
To illustrate, let’s consider two scenarios:
- Scenario 1: All the arrows in a row point in the same direction: ↑ ↑ ↑ ↓ ↑ ↑ ↑. In this case, you need to pay attention to the middle arrow and notice that it points down, even though its neighbors point up.
- Scenario 2: Color spots where the middle spot is different: red, red, blue, red, red. The task is to identify the color of the central spot while ignoring the rest.
The Flanker Task is especially useful for studying cognitive flexibility and attention, as it requires the brain to work at full capacity to solve such a complex task.
Brain-Boosting Exercise: The Flanker Task
The flanker task is a unique diagnostic method used to identify psychological and neurological conditions, such as Parkinson’s disease. This approach becomes particularly effective when used in conjunction with the Stroop test, creating a powerful tool to assess concentration and attention deficits in patients.
However, the potential applications of the flanker task extend well beyond medical diagnostics. It’s an excellent brain-training and personal development tool. For instance, in childhood psychology, the flanker task is widely used to evaluate attention span and focus distribution in children. By studying a child’s responses, psychologists can pinpoint areas of cognitive weakness and turn them into opportunities for enhancement. Imagine a group of young explorers eagerly tackling these tasks, learning to concentrate and block out distractions. Such experiences are invaluable for developing cognitive skills.
But don’t think the flanker task is just for kids. Adults can reap numerous benefits as well. It sharpens logical thinking and improves focus, even amidst constant distractions. Additionally, it enhances peripheral vision, which is useful in everyday life. Games and exercises based on the flanker task serve as tools for intellectual skill development and help form new neural connections. These advancements enable adults to maintain a high level of mental activity and flexibility.
Some companies are actively integrating the flanker task into their programs to nurture cognitive thinking. For instance, Eriksen offers a free “Neurobics” course based on the principles of the flanker task. This course is designed to enhance attention, concentration, thinking, and memory. Just imagine how, by utilizing such a course, you can boost your cognitive abilities, acquire new skills, and notice a significant increase in your productivity both at work and in your personal life. These kinds of exercises can be a major breakthrough in personal development, opening up new opportunities for professional and personal growth.
