Abstract

Alexithymia is a personality trait involving deficits in emotional processing. The personality construct has been extensively validated, but the underlying neural and physiological systems remain controversial. One theory suggests that low-level somatosensory mechanisms act as somatic markers of emotion, underpinning cognitive and affective impairments in alexithymia. In two separate samples (total N=100), we used an established Quantitative Sensory Testing (QST) battery to probe multiple neurophysiological submodalities of somatosensation, and investigated their associations with the widely-used Toronto Alexithymia Scale (TAS-20). Experiment one found reduced sensitivity to warmth in people with higher alexithymia scores, compared to individuals with lower scores, without deficits in other somatosensory submodalities. Experiment two replicated this result in a new group of participants using a full-sample correlation between threshold for warm detection and TAS-20 scores. We discuss the relations between low-level thermoceptive function and cognitive processing of emotion.

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?

  • Alexithymia is associated with reduced perception of thermal sensation.

    “another study reported that alexithymia was associated with reduced perception of thermal sensation (Borhani et al., 2017).”

    From Atypical interoception as a common risk factor for psychopathology: A review (2021) · cites this paper as Borhani et al., 2017

    The Discussion reports lower sensitivity to non-noxious warmth in people with high alexithymia. The claim broadens this to thermal sensation generally, whereas the paper says perception of innocuous cold and noxious heat was unaffected. Page numbers were not provided in our copy.

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.
