Seeking Proxies for Internal States as a Possible Alternative for Rationality and Experientiality

Abstract

The Cognitive-Experiential Self-Theory (CEST) proposes rationality and experientiality as independent personality constructs explaining how people process information. Recent empirical studies show that some people have low scores on both of these dimensions (the so-called disengaged profile). Another model, Seeking Proxies for Internal States (SPIS), primarily proposed to explain obsessive-compulsive tendencies, provides a framework under which both rationality and experientiality can be understood as internal resources of a person. Low rationality and experientiality could thus be overcome by seeking external clues. In two subsequent studies on independent nonclinical samples (psychology students N = 268 and technical sciences students N = 549), we examined the relationship between constructs from CEST and SPIS models, and in addition, explored their patterns of interoceptive awareness (IA) in Study 2. A latent profile analysis showed that the disengaged profile was related to high SPIS and OC tendencies in both samples. In addition, rationality and experientiality had similar and more positive correlations with some IA dimensions, compared to SPIS (and OCI)-IA correlations. Thus, impaired connection to internal states together with OC tendencies might contribute to the understanding of the specific thinking style of those who do not primarily rely on either rationality or experientiality.
