Cognitive Flexibility May Shield Latinx Children from the Mental Health Toll of Community Violence

For children growing up in neighborhoods where violence is part of the soundscape, the psychological cost can be enormous. Yet not every child who witnesses a beating or hears gunshots develops anxiety or depression. A new study published in Child Psychiatry & Human Development offers a clue to why: the ability to mentally shift gears, known as cognitive flexibility, appears to buffer Latinx children against the internalizing symptoms that typically follow exposure to community violence. The findings, from psychologists Alexandra Zax of the University of Illinois Chicago and Omar G. Gudiño of the Child Mind Institute, suggest that a measurable executive skill could serve as a marker of resilience and even a target for intervention.

The research team recruited 50 Latinx students in grades three through five from a charter school in the Kansas City metropolitan area that serves a predominantly Latinx student body. The children, whose average age was just under ten, completed a battery of standardized assessments administered by bilingual research staff. Community violence exposure was measured with the Community Experiences Questionnaire, which asks children how often they have been victims of or witnesses to threats, beatings, weapon attacks, and shootings. Mental health symptoms were assessed with the Revised Child Anxiety and Depression Scale, and cognitive flexibility was measured using the computerized Wisconsin Card Sorting Test, a classic neuropsychological task in which sorting rules change without warning and the child must detect and adapt to the new rule.

The Wisconsin Card Sorting Test works by rewarding one sorting principle, such as color, shape, or number, and then silently switching to another. Children who keep sorting by the old rule despite corrective feedback commit what researchers call perseverative errors, and these errors are considered the clearest behavioral signature of reduced cognitive flexibility. In this study, fewer perseverative errors meant greater flexibility. The bilingual component of the study relied on the Woodcock-Muñoz Language Survey III, which yielded separate standard scores for English and Spanish proficiency. Rather than sorting children into bilingual and monolingual categories, the researchers calculated the absolute difference between each child’s English and Spanish scores, treating bilingualism as a continuum of balanced proficiency.

The core results were strikingly clear. Greater exposure to community violence was associated with more symptoms of both anxiety and depression, consistent with a large body of prior research linking violence exposure to internalizing problems. But the strength of that association depended on the child’s cognitive flexibility. Among children with high levels of flexibility, the link between violence exposure and internalizing symptoms was statistically indistinguishable from zero. Among children at the median level, the association was significant, and among children with the lowest flexibility, it was strongest. In the combined anxiety and depression model, the interaction term accounted for an additional 7.1 percent of the variance in symptoms, and a parallel pattern emerged for depressive symptoms specifically, where the interaction added 8.4 percent of explained variance.

The moderation effect for anxiety alone followed the same direction but fell just short of statistical significance, with a p-value of .063. The authors interpret the overall pattern through the lens of emotion regulation. Children with greater cognitive flexibility may be better able to disengage from threat-focused or ruminative thinking and redirect attention toward alternative appraisals and goal-directed coping. Children with lower flexibility, by contrast, may become stuck in perseverative, worried thought loops after witnessing or experiencing violence, a process that gradually builds toward anxiety and depression. This account aligns with cognitive-behavioral theory, in which the ability to generate alternative explanations for distressing events is a cornerstone of adaptive functioning, and with neurobiological evidence that trauma alters fronto-limbic circuits supporting executive control.

Not every hypothesis survived the data, however. The study set out to test the controversial idea of a bilingual advantage, the notion that managing two languages trains domain-general executive abilities. Bilingual speakers must constantly disengage from one linguistic system and select another as conversational partners and settings change, and some studies have found superior performance on switching tasks as a result. But the evidence is deeply mixed. One meta-analysis cited in the paper found support for a bilingual advantage in only 54.3 percent of reviewed studies, with 28.3 percent producing mixed findings and 17.4 percent finding null or contrary effects. In the present sample, the English-Spanish proficiency difference scores did not predict cognitive flexibility at all, and bilingualism was also unrelated to mental health symptoms, whether directly or in combination with flexibility.

The authors offer several possible explanations for these null results. The school’s predominantly Latinx environment may have meant that the cultural contexts children navigate, home versus school, were not distinct enough to demand frequent cognitive switching. A related possibility is that cognitive benefits attributed to bilingualism may actually stem from biculturalism, the demands of navigating two cultural worlds. Supporting this idea, a prior study found that Turkish-German children who identified equally with both cultures outperformed peers on a switching task. The sample also showed limited variability in Spanish proficiency: 76 percent of children scored in the Initial or Early Development range in Spanish, while only 14 percent reached Emerging Proficiency or higher, reflecting the English-dominant profiles typical of children from language-minority households in the United States. With so little balanced bilingualism, detecting an association may have been statistically difficult from the start.

Important caveats temper the headline finding. The sample was small, and a sensitivity analysis showed the study was powered only to detect medium or larger interaction effects. Community violence exposure was also relatively low: half of the children reported no direct victimization and 44 percent reported no witnessed violence, and mean symptom scores fell well below clinical thresholds. The authors caution that the results may not generalize to youth experiencing more frequent or severe violence, and that the significant moderation effect could be unstable given the restricted range. The cross-sectional design also prevents any conclusions about causality or the temporal ordering of exposure, flexibility, and symptoms. Notably, the researchers stress that individual-level factors like cognitive flexibility should not be framed as substitutes for addressing the structural conditions, including residential segregation, discrimination, and immigration-related stressors, that produce unequal exposure to violence in the first place.

Still, the practical implications are compelling. Because cognitive flexibility is modifiable, therapies that train it, such as cognitive behavioral therapy, acceptance and commitment therapy, and dialectical behavior therapy, could help protect vulnerable children. The authors point to recent evidence that trauma-focused cognitive behavioral therapy reduces executive function difficulties in youth exposed to interpersonal violence, with improved executive function tracking reductions in PTSD symptoms among adolescents. Screening for flexibility deficits could also allow clinicians to tailor interventions for children at heightened risk. As the fastest-growing youth subgroup in the United States, Latinx children stand to benefit enormously from such targeted supports, provided they complement rather than replace broader community and systems-level prevention.
