摘要

Adversity in childhood, which includes adverse life experiences such as abuse and neglect, but can also be more broadly understood to encompass household dysfunction and uncertainty, has been widely linked to poorer cognitive and mental health outcomes and is often interpreted within a deficit-model framework. However, emerging evidence suggests that certain forms of early adversity, particularly exposure to uncertainty, may also foster context-specific cognitive adaptations. Drawing on the specialisation–sensitisation framework, the present study examined whether exposure to childhood uncertainty and adverse life experiences is associated with enhanced executive function (EF) performance under uncertainty-primed conditions in adulthood. In a quasi-representative UK sample (N = 435), participants completed validated measures of childhood uncertainty and childhood adversity alongside EF tasks assessing cognitive flexibility, inhibitory control, and working memory, following random assignment to either uncertainty or control priming. Higher childhood uncertainty and adversity exposure were associated with significantly better cognitive flexibility and inhibitory control performance under uncertainty priming, with no significant disadvantage under control conditions. An examination of the timing of adversity showed that early childhood exposure was associated with lower adult EF performance, regardless of priming context. Exposure to adversity in middle childhood was associated with a performance advantage under uncertainty priming conditions. Regarding adversity type, peer and family adversity were associated with overall cognitive flexibility performance disadvantages, whereas neglect exposure was associated with a cognitive flexibility performance advantage under uncertainty priming conditions. These findings add nuance to the discussion of impairments following childhood adversity and highlight the potential for adaptive calibration of cognitive systems. This work supports the need for context-sensitive assessments and interventions that acknowledge both the risks and the functional adaptations associated with early life adversity.

Public Relevance

Adults who experienced childhood adversity or uncertainty may perform better on executive function tasks when thinking about uncertain situations, suggesting potential hidden strengths shaped by early life experiences.

Key Findings

1. When primed for uncertainty, participants with exposure to childhood adversity and uncertainty perform better in executive function tasks.

2. Early-life adversity or uncertainty may thus enhance adults’ executive function performance in unpredictable task contexts, revealing adaptive strengths shaped by challenging childhoods.

3. The long-term effects of childhood adversity may be more nuanced than dose-response models (i.e., higher adversity = higher impairment) suggest, with results indicating that both type and timing shape cognitive functioning in adulthood.
