Abstract

Significance: Childhood poverty has been linked to emotion dysregulation, which is further associated with negative physical and psychological health in adulthood. The current study provides evidence of prospective associations between childhood poverty and adult neural activity during effortful attempts to regulate negative emotion. Adults with lower family income at age 9 exhibited reduced ventrolateral and dorsolateral prefrontal cortex activity and failure to suppress amygdala activation at age 24. Chronic stressor exposure across childhood mediated the relations between family income at age 9 and prefrontal cortex activity. The concurrent adult income, on the other hand, was not associated with neural activity. The information on the developmental timing of poverty effects and neural mechanisms may inform early interventions aimed at reducing health disparities.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Chronic stress has also been shown to weaken PFC functional connectivity and PFC regulation of the amygdala, and to increase the volume of the putamen, thus accentuating the switch from flexible goal-directed to habitual responding.

    “Chronic stress has also been shown to weaken PFC functional connectivity80 and PFC regulation of the amygdala81, and to increase the volume of the putamen, thus accentuating the switch from flexible goal-directed to habitual responding82.”
  • Groups who experienced greater adversity demonstrated greater neural reactivity to negative images in amygdala and different patterns of activation in prefrontal cortex compared to groups experiencing less adversity.

    “In both studies, the groups who had experienced greater adversity demonstrated greater neural reactivity to negative images in amygdala and different patterns of activation in prefrontal cortex compared to the groups experiencing less adversity.”
  • Growing up in poverty can have a negative effect on the developing brain and one's ability to regulate emotions.

    “Growing up in conditions of poverty also can have a negative effect on the developing brain and one's ability to regulate emotions.”
  • Acute stress and chronic stress can have deleterious effects on cognitive abilities.

    “However, acute stress (e.g. test anxiety) and outside factors contributing to chronic stress (e.g. poverty) can have deleterious effects on one's cognitive abilities [4,30,31].”
  • Adults who experienced poverty during childhood show decreased dlPFC and vlPFC activation and increased amygdala activation during a reappraisal task compared to adults with higher childhood family incomes.

    “Kim et al., found decreased dlPFC and vlPFC activation and increased amygdala activation during a reappraisal task in adults who had experienced poverty during childhood compared to adults whose families had higher incomes during childhood [31].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
