Abstract
Objective: Exposure to neighborhood violence may have negative implications for adults' cognitive functioning, but the ecological sensitivity of these effects has yet to be determined. We first evaluated the link between exposure to neighborhood violence and two latent constructs of cognitive function that incorporated laboratory-based and ambulatory, smartphone-based, cognitive assessments. Second, we examined whether the effect of exposure to violence was stronger for ambulatory assessments compared to in-lab assessments.
Methods: We used data from 256 urban-dwelling adults between 25 and 65 years old (M = 46.26, SD = 11.07); 63.18% non-Hispanic Black, 9.21% non-Hispanic White, 18.41% Hispanic White, 5.02% Hispanic Black, and 4.18% other. Participants completed baseline surveys on neighborhood exposures, cognitive assessments in a laboratory/research office, and ambulatory smartphone-based cognitive assessments five-times a day for 14 days.
Results: Exposure to neighborhood violence was associated with poorer performance in a latent working memory construct that incorporated in-lab and ambulatory assessments, but was not associated with the perceptual speed construct. The effect of exposure to neighborhood violence on the working memory construct was explained by its effect on the ambulatory working memory task and not by the in-lab cognitive assessments.
Conclusion: This study shows the negative effect that exposure to neighborhood violence may have on everyday working memory performance in urban-dwelling adults in midlife. Results highlight the need for more research to determine the sensitivity of ambulatory assessments to quantify the effects of neighborhood violence on cognitive function.
