Fig. 1.

2 × 2 dimensional structure of interoception, distinguishing between different measurement types (beliefs or performance) and interoceptive abilities (accuracy or attention). Metacognitive ability (referred to as interoceptive awareness; Garfinkel and Critchley, 2013, or interoceptive insight; Khalsa et al., 2018) is shown by the black arrows, reflecting the extent to which beliefs and performance are related, either within the accuracy or attention ability. Figure adapted from Murphy, Catmur, and Bird (2018) and Murphy, Catmur, and Bird (2019).
