Eligibility

Inclusion criteria

Inclusion criteria: 1. Adults with age group of 18 to 25 year. 2. People living in delhi ncr area more than 3 years. 3. No past history of any neurological disorder. 4. Have normal or corrected-to-normal vision and hearing. 5. Are able to understand and follow test instructions in English.

Exclusion criteria

Exclusion criteria: 1. Have a history of neurological disorders (e.g., epilepsy, stroke, traumatic brain injury) that may affect reaction time and short term memory 2. Have chronic respiratory diseases (e.g., asthma, COPD) that may alter response to air pollution exposure. 3. Have visual or auditory impairments not corrected by aids, which could influence reaction measurement. 4. Have prior training or repeated exposure to reaction time tests, which could bias results. 5. Have consumed alcohol, caffeine, or psychoactive substances within 12 24 hours prior to assessment.

Design outcomes

Primary

MeasureTime frame
Short-term memory performance among young adults, measured using the Rey Auditory Verbal Learning Test (RAVLT) score in relation to Air Quality Index (AQI) exposure.Timepoint: Short-term memory performance will be assessed once during the study visit, immediately after administration of the Rey Auditory Verbal Learning Test (RAVLT)

Secondary

MeasureTime frame
Relationship between AQI levels & reaction time among young adultsTimepoint: Reaction time will be assessed once during the study visit after completion of the Choice Ruler Drop Test trials.
