Symbols will flash by. Count only the ⭐ 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.
Pair with the Stroop Test and Go/No-Go Test for a full executive attention profile.
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.
