Dissociations between psychobiologic reactivity and emotional expression in children
Abstract
Asymmetries in the surface temperature of the fingertips of the right and left hands were gathered on four independent samples of children ranging in age from 4 to 8 years (N = 398) while watching film clips in order to determine if the direction or magnitude of asymmetry was related to behavioral signs of fear or inhibition. The left index finger was cooler than the right index finger for all four groups. The right ring finger was cooler than the left ring finger for two of the four groups, and of similar temperature for the other two groups. There was no relation between direction of asymmetry and behavior and only a modest relation between a large temperature asymmetry between the index fingers and behavioral signs of very high fear or inhibition. There was no relation between asymmetry and fear or inhibition across all children, suggesting the utility of examining extreme scores.

In the citing paper
“a number of studies have hinted to the provocative possibility that ANS-associated somatic signs may not be as strongly linked to emotional expression (e.g., Quas et al, 2000; Stroud et al, 2009) or to optimizing risky decision-making (e.g., Crone & van der Molen, 2007) during development as in adulthood.”

“children that showed greater cardiac reactivity to a needle puncture for blood draw even tending to exhibit less behavioral evidence of negative affect and emotional distress to the procedure (Quas et al, 2000).”

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.
