Background:

Attentional deficits significantly impact daily functioning.
Current methods for assessing attention are often time-consuming and complex.
There is a need for rapid and accessible tools to evaluate attentional capabilities.

Purpose of the Study:

To investigate electroencephalography (EEG) patterns during attention tasks.
To gather foundational data for developing a novel EEG-based attention assessment tool.
To explore the relationship between EEG features and attentional performance.

Main Methods:

Twenty healthy young adults underwent EEG monitoring during attention-based tasks (digit-forward and digit-backward).
Portable EEG devices were utilized for cerebral activity examination.
Statistical analysis (Mann-Whitney U test) compared EEG power levels between low- and high-attention groups.

Main Results:

The high-attention group exhibited higher δ wave power (L-temporal, bilateral parietal) and β/γ wave power (R-occipital) during digit-forward tasks.
During digit-backward tasks, the high-attention group showed higher θ wave power (R-frontal) and α wave power (bilateral frontal).
Lower θ, α, and β wave power in the right hemisphere was associated with the low-attention group.

Conclusions:

Specific EEG wave patterns in distinct brain regions differentiate individuals with high and low attentional function.
Reduced right-hemisphere θ, α, and β band activity may serve as potential biomarkers for attentional deficits.
EEG holds promise as a tool for developing a quick and easy evaluation of attentional function.
