Plasticity for Affective Neurocircuitry: How the Environment Affects Gene Expression

Fox, Nathan A., Hane, Amie A., Pine, Daniel S.·2007·Current Directions in Psychological Science

Abstract

We ( Fox et al., 2005 ) recently described a gene-by-environment interaction involving child temperament and maternal social support, finding heightened behavioral inhibition in children homozygous or heterozygous for the serotonin transporter (5HTTLPR) gene short allele whose mothers reported low social support. Here, we propose a model, Plasticity for Affective Neurocircuitry, that describes the manner in which genetic disposition and environmental circumstances may interact. Children with a persistently fearful temperament (and the 5HTTLPR short allele) are more likely to experience caregiving environments in which threat is highlighted. This in turn will exacerbate an attention bias that alters critical affective neurocircuitry to threat and enhances and maintains anxious behavior in the child.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • Certain genes can confer environmentally sensitive plasticity, so the same genetic variant may increase risk under harmful conditions but provide benefit under favorable conditions.

    “It is also possible for certain genes to confer environmentally sensitive “plasticity” such that the same genetic variant may confer risk under harmful environmental circumstances but provide benefit under auspicious conditions”

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.
