A multidimensional approach to the self in non-human animals through the Pattern Theory of Self.

Summary

The self in non-human animals is often studied in a limited, dichotomous way that separates low-level bodily and affective aspects from high-level cognitive ones. A proposed framework based on the Pattern Theory of Self (PTS) treats the self as a dynamic, multidimensional construct with graded, non-hierarchical dimensions—ranging from bodily and affective to intersubjective and normative. This approach accommodates variability within and across species, allowing researchers to investigate how the self emerges in different degrees and forms shaped by ecological niches and adaptive demands, without relying on anthropocentric biases.

Abstract

In the last decades, research on animal consciousness has advanced significantly, fueled by interdisciplinary contributions. However, a critical dimension of animal experience remains underexplored: the self. While traditionally linked to human studies, research focused on the self in animals has often been framed dichotomously, distinguishing low-level, bodily, and affective aspects from high-level, cognitive, and conceptual dimensions. Emerging evidence suggests a broader spectrum of self-related features across species, yet current theoretical approaches often reduce the self to a derivative aspect of consciousness or prioritize narrow high-level dimensions, such as self-recognition or metacognition. To address this gap, we propose an integrated framework grounded in the Pattern Theory of Self (PTS). PTS conceptualizes the self as a dynamic, multidimensional construct arising from a matrix of dimensions, ranging from bodily and affective to intersubjective and normative aspects. We propose adopting this multidimensional perspective for the study of the self in animals, by emphasizing the graded nature of the self within each dimension and the non-hierarchical organization across dimensions. In this sense, PTS may accommodate both inter- and intra-species variability, enabling researchers to investigate the self across diverse organisms without relying on anthropocentric biases. We propose that, by integrating this framework with insights from comparative psychology, neuroscience, and ethology, the application of PTS to animals can show how the self emerges in varying degrees and forms, shaped by ecological niches and adaptive demands.
