“…La integración de las posibilidades con la ergonomía en la investigación de neuroarquitectura permite investigar cómo las propiedades arquitectónicas se alinean con las capacidades incorporadas de los usuarios. Por ejemplo, las variables de la investigación podrían abarcar tanto las dimensiones ambientales (alturas de escaleras, tamaños de aberturas) como las capacidades físicas de los participantes (longitud de las piernas, cambios corporales) para comprender su complementariedad a escala ecológica 79 . En esencia, la psicología ecológica amplía las investigaciones neuroarquitectónicas más allá de la estética, acercándolas hacia una ergonomía integral.…”

“…Numerous studies show that people are able to perceive self-affordances ( Warren and Whang, 1987 ; Mark et al, 1997 ; Creem-Regehr et al, 2013 ) grounded in an egocentric point of view and scaled in terms of one’s body dimensions. Younger children make more errors than elders and adults in estimation for reaching, stepping and ducking.…”

Self-consciousness develops through a long process, from pre-reflexive consciousness relying on body perception, to “meta” self-awareness. It emerges from the imitative experience between children and their peers. This experience linked to the capacity to test structural similarities between oneself and others, is addressed according to the concept of interpersonal affordance. We hypothesize that the opportunity for co-actors to engage in a process of interpersonal coordination is underlined by their similarity in terms of morphological, behavioral and motor features. This experience can sustain the emergence of new affordances for objects for each co-actor, as well as new affordances in terms of joint actions. We apply this idea in the context of peer-mediated interventions (PMI) in autism spectrum disorder (ASD). We argue that, in PMI, an encounter between children with autism and similar peers would foster the opportunity to engage in a spontaneous process of interpersonal coordination. This process would enable the development of self-consciousness and the emergence of perception of interpersonal, self and other’s affordances for children with autism. We conclude that metrics to assess morphological, behavioral and motor similarity should then be defined and used in future studies to test our hypothesis in children with autism versus TD children or between children with autism.

“…size) constrains the perception of objects and the generation of motor responses. For instance, humans evaluate the climbability of steps based on their leg length ( Mark, 1987 ; Warren, 1984 ), and determine the navigability of apertures according to the critical aperture-to-shoulder-width ratio ( Warren and Whang, 1987 ). Additionally, grasping strategies have been shown to be contingent upon object size relative to one’s body ( Cesari and Newell, 2000 ; Newell et al, 1989 ) or hand size ( Castiello et al, 1993 ; Tucker and Ellis, 2004 ).…”

Body size as a metric for the affordable world

The physical body of an organism serves as a vital interface for interactions with its environment. Here we investigated the impact of human body size on the perception of action possibilities (affordances) offered by the environment. We found that the body size delineated a distinct boundary on affordances, dividing objects of continuous real-world sizes into two discrete categories with each affording distinct action sets. Additionally, the boundary shifted with imagined body sizes, suggesting a causal link between body size and affordance perception. Intriguingly, ChatGPT, a large language model lacking physical embodiment, exhibited a modest yet comparable affordance boundary at the scale of human body size, suggesting the boundary is not exclusively derived from organism-environment interactions. A subsequent fMRI experiment showed that only the affordances of objects within the range of body size were represented in the brain, suggesting that objects capable of being manipulated are the only objects capable of offering affordance in the eyes of an organism. In summary, our study suggests a novel definition of object-ness in an affordance-based context, advocating the concept of embodied cognition in understanding the emergence of intelligence constrained by an organismâ€™s physical attributes.
