Abstract
This study used a visual search task created in PsychoPy to examine the effects of brief guided meditation on cognitive function under time constraints. The test was done in two phases, before and after a 5-day meditation intervention, by ten individuals with normal or corrected vision, both with and without a time-based stressor. In order to target the brain regions involved in stress regulation and attention—specifically, the hypothalamus, thalamus, and hippocampus—the meditation routine combined Nadi Shodhana (alternate nostril breathing), yogic postures (Vrikshasana, Paschimottanasana, Sarvangasana), Trataka, or mindfulness meditation, and Bhramari (humming breath). According to pre-test data, during stress, reaction times were slower, which may indicate cognitive strain and attentional overload. Even under pressure, participants' reaction times were faster or more stable, according to post-intervention data, indicating increased attentional control, emotional control, and cognitive flexibility. These modifications are consistent with the INLM concept (Information, Need, Limitations, Mechanisms), which describes how adaptive mechanisms and internal regulation might improve cognitive function in the face of limitations. In order to enhance mental effectiveness and stress resilience in cognitively taxing circumstances, this study advocates the incorporation of holistic, not pharmaceutical in nature practices such as yoga and mindfulness.
