Symbols will flash by. Count only the โญ Stars - ignore everything else. Enter your count at the end. Tests selective and sustained attention.
Selective attention is the ability to focus on relevant information while ignoring distractors. Sustained attention is maintaining focus over time. Both are crucial for academic learning, driving, and professional performance. Attention control is a core human benchmark in cognitive psychology research.
Pair with the Stroop Test and Go/No-Go Test for a full executive attention profile.
ReflexBenchmark offers a free human benchmark for attention that rivals what you'd find in clinical research settings โ no appointment needed.
Attention is not a single ability but a family of distinct capacities. This test measures two: selective attention - focusing on the relevant target (the star symbol) while filtering distractors - and sustained attention - maintaining this focus across the full duration of the stream without mind-wandering. Both are controlled by overlapping but distinct fronto-parietal networks and both are essential for academic and professional performance.
The key challenge is that distractors compete for attentional resources. When you see a salient symbol that resembles the target, bottom-up attentional capture can briefly redirect focus - causing a count error. Avoiding this while maintaining vigilance over the entire stream requires the interplay of top-down control (what I'm looking for) and bottom-up filtering (what I'm ignoring). This is exactly the cognitive challenge faced in real-world tasks like proofreading, air traffic control, and surgical monitoring.
Even a silent phone on the desk reduces attention capacity by capturing background processing resources.
Sustained attention is disproportionately sensitive to sleep loss - the first cognitive function to degrade after even mild sleep restriction.
8 weeks of mindfulness meditation practice produces measurable improvements in sustained attention and reduced mind-wandering.
Selective attention is focusing on a relevant target while filtering out distractors, while sustained attention is maintaining that focus over the entire duration of a task without mind-wandering. This test measures both simultaneously.
Even a silent phone on the desk reduces available attention capacity by consuming background cognitive processing resources, a well-documented effect sometimes called "brain drain."
Yes. Eight weeks of regular mindfulness meditation practice produces measurable improvements in sustained attention and reduces mind-wandering, according to multiple controlled studies.
Frequent task-switching doesn't damage attention permanently, but habitual multitasking can make it feel harder to sustain focus on a single task, since your brain becomes used to shifting frequently.
Most adults can maintain deep, focused attention for roughly 20-40 minutes before performance and accuracy start to decline, depending on the task's difficulty and personal factors like sleep.
Moderate caffeine can improve alertness and attention in the short term for many people, though excessive intake can increase anxiety and actually impair sustained focus.
They're closely related but not identical - attention is the broader ability to selectively process information, while concentration refers more specifically to sustaining that focus over time on one task.
Yes, sleep deprivation is one of the most well-documented factors that impairs sustained and selective attention, often producing effects comparable to mild alcohol intoxication.
Sustained attention tends to remain relatively stable through adulthood but can decline somewhat with age, particularly in tasks requiring rapid shifts between competing stimuli.
Proofreading, air traffic control, and surgical monitoring all require the same interplay of top-down focus and bottom-up distractor filtering that this test measures.
