Henry Wellman (2020) explores the development of "theory of mind"—our ability to understand and predict others' mental states. He argues that this skill is fundamental to human social life and emerges through a natural, step-by-step process from early childhood. Unlike skills that can be directly taught, such as arithmetic, the development of theory of mind is an intrinsic part of cognitive and social growth. Wellman emphasises that this process is crucial for engaging in social interactions, interpreting narratives, and constructing a coherent life story. A failure to develop these abilities can lead to profound difficulties in navigating the social world. By successfully acquiring a theory of mind, individuals gain insight into human nature, improve their ability to communicate and learn from others, and enhance their overall social competence.
Cultural mind reading
In contrast, Heyes and Frith (2014) present a cultural evolutionary perspective on mind reading, drawing a distinction between implicit and explicit mind reading. Implicit mind reading, which emerges early in infancy, allows individuals to anticipate others' actions based on mental states such as beliefs, even false ones. This form of mind reading operates automatically and relies on basic neurocognitive mechanisms that may be genetically inherited. Explicit mind reading, however, develops later and requires cultural transmission, verbal instruction, and practice. The authors compare this process to learning to read print: while implicit recognition of symbols may be innate, full literacy depends on education and exposure.
Heyes and Frith argue that explicit mind reading is not a purely biological adaptation but a culturally shaped cognitive skill. This is supported by evidence from twin studies, research on hearing-impaired individuals, and cross-cultural comparisons, all of which indicate that explicit mind reading varies based on cultural background and experiences. Unlike innate perceptual abilities such as colour vision, which are biologically hardwired, explicit mind reading is shaped by social learning and cultural inheritance.
A key insight from their research is that cultural influences do not merely refine an existing biological mechanism but fundamentally transform how humans engage in mind reading. While the neurocognitive foundations for understanding mental states may be present from birth, their full expression into a sophisticated, explicit skill depends on social and linguistic inputs. This perspective challenges the notion that mind reading is purely an evolutionary adaptation and instead highlights the dynamic interplay between biology and culture in cognitive development, emphasising its cultural transmission and variability.
Both Wellman and Heyes & Frith contribute to our understanding of mind reading, but from different angles. Wellman underscores the natural, stepwise development of theory of mind as an essential part of human growth, whereas Heyes and Frith emphasise the role of cultural learning and social transmission in shaping explicit mind reading as a skill that is acquired rather than purely biologically determined. Together, these perspectives provide a nuanced view of how we come to understand others' minds, balancing innate neurocognitive capacities with the profound influence of culture and learning.
