However, it remains unclear whether such effects are driven by the chemical properties of odorants or by mood\u2010related associations, especially under conditions of high cognitive demand. This study examined whether limonene, a key citrus odorous compound, modulates cognitive processing during a visual 2\u2010back task under different levels of perceptual load.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We developed a 2\u2010back working memory task using color lightness discrimination. The task included both low\u2010load (orange) and high\u2010load (gray) conditions. Participants wore a non\u2010woven mask impregnated with the odor solution and performed the task under two odor conditions: limonene exposure and no odor.

The observed P300 suppression suggests that this component may be sensitive to decreases in attentional allocation that behavioral measures failed to detect. Moreover, these results replicate and extend previous findings of limonene\u2010induced P300 suppression, supporting the reproducibility of limonene's modulatory effect on neural markers of cross\u2010modal attentional processing.<\/jats:p>\n
