It has recently been proposed that measures of the perception of the state of one’s own body
(‘interoception’) can be categorized as one of several types depending on both how an
assessment is obtained (objective measurement vs. self-report) and what is assessed (degree
of interoceptive attention vs accuracy of interoceptive perception). Under this model, a
distinction is made between beliefs regarding the degree to which interoceptive signals are
the object of attention, and beliefs regarding one’s ability to perceive accurately interoceptive
signals. This distinction is difficult to test, however, because of the paucity of measures
designed to assess self-reported perception of one’s own interoceptive accuracy. This paper
therefore reports on the development of such a measure, the Interoceptive Accuracy Scale
(IAS). Use of this measure enables assessment of the proposed distinction between beliefs
regarding attention to, and accuracy in perceiving, interoceptive signals. Across six studies
we report on the development of the IAS and, importantly, its relationship with measures of
trait self-reported interoceptive attention, objective interoceptive accuracy, confidence in the
accuracy of specific interoceptive percepts, and metacognition with respect to interoceptive
accuracy. Results support the distinction between individual differences in perceived
attention towards interoceptive information and the accuracy of interoceptive perception.

Interoception, Contemplative Practice, and Health
Farb, N; Daubenmier, J; Price, CJ; et al. (Frontiers, 22 May 2015)Interoception can be broadly defined as the sense of signals originating within the body. As such, interoception is critical for our sense of embodiment, motivation and well-being. And yet, despite its importance, interoception ... -
