Abstract

This study investigated dopamine receptor genes (DRD2 and DRD4) and maternal sensitivity as predictors of infant respiratory sinus arrhythmia (RSA) and RSA reactivity, purported indices of vagal tone and vagal regulation, in a challenge task at 3, 6, and 12 months in 173 infant–mother dyads. Hierarchical linear modeling (HLM) revealed that at 3 and 6 months, RSA withdrawal in response to maternal separation was greater (suggesting expected physiological regulation) in infants without the DRD2 risk allele than those with the risk allele. At 12 months, infants with the risk allele who were also exposed to maternal sensitivity showed levels of RSA withdrawal comparable to infants who were not at genetic risk. Findings demonstrate the importance of developmental analysis of gene–environment interaction.

Claims other papers make about this one

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

  • Many genes that can affect stress response system functioning show widespread allelic variation.

    “widespread allelic variation exists in many genes that can affect SRS functioning”

    From The Adaptive Calibration Model of stress responsivity (2011) · cites this paper as Propper et al., 2008

  • This developmental shift is likely marked by increased parasympathetic tone and responsivity.

    “At the physiological level, this shift is likely to be marked by increased parasympathetic tone and responsivity (e.g., Propper et al., 2008).”

    From The Adaptive Calibration Model of stress responsivity (2011) · cites this paper as Propper et al., 2008

  • Maternal sensitivity moderates the relation between purported genetic risk for behavior problems and development of infants' vagal regulation.

    “In a separate published report of the same study from which participants were drawn for the current article, maternal sensitivity was found to moderate the relation between purported genetic risk for behavior problems and development of infants' vagal regulation (Propper et al., 2008).”
  • Infants carrying the risk A1+ allele failed to show expected RSA withdrawal in response to mothers' disengagement in the still-face episode at 3 and 6 months of age.

    “Infants carrying the risk A 1 + allele of the dopamine receptor D2 gene, which has been associated with novelty seeking, aggressiveness, and impulse control disorders in adolescents and adults, failed to show expected RSA withdrawal in response to mothers' disengagement in the still-face episode of the FFSFP at 3 and 6 months of age.”
  • Infants at genetic risk whose mothers were rated lower in sensitivity continued to show a failure to withdraw RSA.

    “Infants at genetic risk whose mothers were rated lower in sensitivity continued to show a failure to withdraw RSA.”

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.
