Childhood maltreatment and its effect on neurocognitive functioning: timing and chronicity matter

Abstract

Childhood maltreatment represents a complex stressor, with the developmental timing, duration, frequency, and type of maltreatment varying with each child (Barnett, Manly, & Cicchetti, 1993; Cicchetti & Manly, 2001). Multiple brain regions and neural circuits are disrupted by the experience of child maltreatment (Cicchetti & Toth, in press; DeBellis et al., 2002; McCrory & Viding, 2010; Teicher, Anderson, & Polcari, 2012). These neurobiological compromises indicate the impairment of a number of important cognitive functions, including working memory and inhibitory control. The present study extends prior research by examining the effect of childhood maltreatment on neurocognitive functioning based on developmental timing of maltreatment, including onset, chronicity, and recency, in a sample of 3- to 9-year-old nonmaltreated (n= 136) and maltreated children (n= 223). Maltreated children performed more poorly on inhibitory control and working-memory tasks than did nonmaltreated children. Group differences between maltreated children based on the timing of maltreatment and the chronicity of maltreatment also were evident. Specifically, children who were maltreated during infancy, and children with a chronic history of maltreatment, exhibited significantly poorer inhibitory control and working-memory performance than did children without a history of maltreatment. The results suggest that maltreatment occurring during infancy, a period of major brain organization, disrupts normative structure and function, and these deficits are further instantiated by the prolonged stress of chronic maltreatment during the early years of life.

TL;DR

This cross-sectional study compared low-SES maltreated and nonmaltreated children aged 3–9 on neurocognitive tasks. Maltreated children showed poorer inhibitory control and working memory, especially when maltreatment began during infancy or persisted across three or more developmental periods.

Key findings

  • Maltreated children had lower inhibitory control/working memory composite scores than nonmaltreated children (M = −0.11, SD = .85 vs. M = .08, SD = .82; F(1, 358) = 9.602, p = .002, η² = .026). No significant group differences appeared for memory, motor control/attention, or the overall cognitive composite.
  • Chronicity mattered: children maltreated across three or more developmental periods scored lower than nonmaltreated children (M = −.42, SD = .96, p = .000) and lower than the one-period group (p = .05). One- and two-period groups did not differ significantly from nonmaltreated children.
  • Onset and recency mattered: infancy-onset maltreatment was associated with lower scores than nonmaltreated status (M = −.32, SD = .91, p = .000) and later onset (p = .036); later onset did not differ from nonmaltreated. Nonmaltreated children outperformed both current-period and past maltreatment groups (p = .004 and p = .05), while current versus past maltreatment did not differ.
  • Subtype count showed both one/two and three/four subtype groups performing worse than nonmaltreated children (p = .021 and p = .002), but the two maltreated groups did not differ from each other (p = .08). At age 4, maltreated children failed the tapping pretest more often (76.3% vs. 40.9%; χ² = 8.174, p = .004).

Methods

  • Cross-sectional comparison of 3- to 9-year-old low-SES children from urban upstate New York. Maltreated children were identified through Department of Human Services/Child Protective Services records and maternal interview; nonmaltreated comparison children were recruited from TANF families with no DHS involvement. The abstract reports 136 nonmaltreated and 223 maltreated children, while the Method section reports 228 maltreated and 142 nonmaltreated children; follow-up analyses use 136 comparison children.
  • Ten neuropsychological tasks assessed inhibitory control/working memory, memory, attention, and motor control. Standardized task variables were combined into inhibitory control/working memory, memory, motor control/attention, and cognitive function composites. ANCOVAs with age in months as a covariate compared groups, and follow-up tests examined maltreatment onset, chronicity, recency, and subtype count on inhibitory control/working memory.

Limitations

  • Stated: the design was cross-sectional with assessment at only one time point, so developmental timing and change could not be directly observed; the author calls for longitudinal and fMRI research.
  • Evident from the text: sample-size figures differ between the abstract/Method and the analysis samples; subtype analyses had a small three-or-more-subtype group (n = 34); the low-SES urban sample may limit generalizability; pretest failures excluded task-specific data; and causal claims cannot be established from the design.

    Maltreatment onset during infancy versus after infancy is a valid index of timing.

    “Onset of maltreatment was examined in relation to the ICWM. Children whose maltreatment onset occurred during infancy (n = 101) were differentiated from those children whose maltreatment onset occurred after infancy (n = 86).”

    Each neurobiological system influences and is influenced by multiple domains of biological and psychological development.

    “Moreover, each of these neurobiological systems influences and is influenced by multiple domains of biological and psychological development.”

    The child-caregiver relationship plays an important role because the precursor of higher cognition during infancy is connecting an act to a consequence.

    “The child-caregiver relationship may also play an important role because the precursor of higher cognition during infancy is connecting an act to a consequence.”

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

  • Childhood trauma exposure during specific phases of development is important to later neurobiological functioning.

    “An emerging literature also suggests childhood trauma exposure during specific phases of development is important to later neurobiological functioning (Andersen et al., 2008; Cowell et al., 2015; Gee and Casey, 2015; Kuhlman et al., 2015)”

Statistics recomputed

Every reported test result, recomputed from its test statistic and degrees of freedom. A result shows as not adding up only once an independent check has confirmed it.

  • Consistentt(354) = 0.78reported n.s. · recomputed p = .436

    “t (354)=.78, ns.”

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Age-four failure percentages cannot come from the stated sample size

    Minor

    With integer group sizes totaling 65, the two failure rates cannot both round to 76.3% and 40.9%. Within that sample-size limit, 76.3% requires a denominator of 38 or 59, while 40.9% requires 22 or 44; no pair totals 65.

  • Motor-control ANCOVA has too many residual degrees of freedom

    Minor

    The initial sample contains 370 children. Even if every child were included, an ANCOVA with a group effect and an age covariate could have at most 367 residual degrees of freedom, rather than 369.

  • Chronicity ANCOVA residual degrees of freedom exceed those allowed by its groups

    Minor

    The three maltreated groups contain 187 children; adding the stated nonmaltreated group of 136 gives 323. An ANCOVA with four groups and an age covariate would have 318 residual degrees of freedom, not 322.

  • Subtype comparison has the wrong numerator degrees of freedom

    Minor

    The reported test compares two maltreatment groups with a nonmaltreated group. An omnibus group effect across three groups has two numerator degrees of freedom, not the reported one.

  • Task categories add up to nine, not ten

    Minor

    The stated categories contain 3 + 4 + 2 = 9 tasks, whereas the sentence says all children were tested on 10.

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.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-06.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-06.

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.
