- Dissociating self reported interoceptive accuracy and attention: Evidence from a Portuguese community samplePublication . Campos, Carlos; Rocha, Nuno; Barbosa, FernandoThe 2x2 factorial model has been recently proposed as a promising framework to measure individual differences in interoception. The first factor addresses which domain is being measured (interoceptive accuracy vs. attention), while the second distinguishes how it is being measured (self-report beliefs vs. objective performance). The current study examined the association between self-reported interoceptive accuracy and attention. We hypothesized no linear association between these constructs, although a quadratic U-shaped association was expected. Furthermore, alexithymia should be differentially related to interoceptive accuracy and attention. An online community sample (*n *= 515) completed the Interoceptive Accuracy Scale (IAS), the Body Perception Questionnaire (BPQ) *ndexing self-reported interoceptive attention, and the Toronto Alexithymia Scale (TAS). Pearson correlations, Steiger’s Z-test, polynomial regression analysis, and two-lines testing were used for statistical analysis. IAS was positively correlated with BPQ, r = .204, p < .001. In the polynomial regression analysis, the linear model indicated a positive association between IAS and BPQ (4.2%), but the quadratic term explained an additional 12.7% of the variance. Two-lines testing indicated a U-shaped association between self-report interoceptive accuracy and attention. IAS was negatively correlated with TAS, r = -.291, p < .001, while there was no significant association between BPQ and TAS, r = -.030, p = .500, as these correlations were statistically different. These results suggest that interoceptive accuracy and attention can be dissociated using self-report measures and may display a quadratic U-shaped association, providing further evidence for the 2x2 factorial model. Future studies should explore the non-linear relationship between interoceptive accuracy and attention using alternative questionnaires and performance-based measures.
- Self-other distinction and individual differences in interoception, empathy, and alexithymiaPublication . Campos, Carlos; Silva, Cláudia; Rocha, Nuno; Barbosa, FernandoTheoretical models have argued for a complex interaction between self-other distinction, interoception, and social cognition, despite inconsistent evidence. To examine the associations between self-other distinction and individual differences in interoception, empathy, and alexithymia. 51 college students (21.82 years; 47.1% male) completed the Imitation-Inhibition Task to assess self-other distinction and an online survey with questionnaires to evaluate empathy (Questionnaire of Cognitive and Affective Empathy), alexithymia (Toronto Alexithymia Scale), interoceptive attention (Body Perception Questionnaire - BPQ) and accuracy (Interoceptive Accuracy Scale). Zero-order correlations, t-tests, and hierarchical linear regressions were implemented for statistical analysis (preregistered at https://osf.io/w4qt6). Self-other distinction (indexed by imitation-inhibition scores) was marginally related to affective empathy, although this association was not significant when controlling for sex (male subjects displayed enhanced self-other distinction and worst affective empathy) and baseline reaction times. Imitation-inhibition was not associated with any other variable of interest. Findings regarding interoceptive attention should be interpreted with caution as only 18 subjects correctly interpreted the BPQ. Despite the reduced sample size, the current findings suggest that self-other distinction, as measured by the Imitation-Inhibition Task, is not associated with individual differences in interoception, empathy, or alexithymia.
