“…Finally, one study examined the development of material property perception for grasping and reaching in early childhood for objects with different rigidity using a 3D motion capture system ( Preißler et al, 2021 ). The task consisted in lifting objects with one of two handles that varied in rigidity (soft and hard) after visual and visual-haptic exploration.…”

The perception of material properties, which refers to the way in which individuals perceive and interpret materials through their sensory experiences, plays a crucial role in our interaction with the environment. Affordance, on the other hand, refers to the potential actions and uses that materials offer to users. In turn, the perception of the affordances is modulated by the aesthetic appreciation that individuals experience when interacting with the environment. Although material perception, affordances, and aesthetic appreciation are recognized as essential to fostering sustainability in society, only a few studies have investigated this subject matter systematically and their reciprocal influences. This scarcity is partially due to the challenges offered by the complexity of combining interdisciplinary topics that explore interactions between various disciplines, such as psychophysics, neurophysiology, affective science, aesthetics, and social and environmental sciences. Outlining the main findings across disciplines, this review highlights the pivotal role of material perception in shaping sustainable behaviors. It establishes connections between material perception, affordance, aesthetics, and sustainability, emphasizing the need for interdisciplinary research and integrated approaches in environmental psychology. This integration is essential as it can provide insight into how to foster sustainable and durable changes.

“…Another important material property in visual perception is the rigidity and softness of materials. Rigidity refers to the material property of resistance to bending, while softness is a material's deformability [19]. These characteristics are strongly linked to the strength of the material, but they differ in that soft, malleable metals can be strong but not rigid, while brittle materials can be rigid but not strong.…”

Unsupervised Learning Can Predict Object Properties of Non-Rigid Mirror Objects in Ambiguous Conditions

Although ‘glossiness’ is an optical property of materials, while ‘softness’ is a mechanical property, there is an intriguing perceptual connection between the two as both specular reflections and shape deformations produce distinctive motion patterns. Observers are generally excellent at determining properties of moving surfaces. However, under certain circumstances, reflections and deformations can actually be confused, with rigidly transforming mirrors appearing non-rigid and deforming matte-textured objects occasionally appearing somewhat shiny. Here, we investigated whether similar broad successes and specific confusions also arise in an unsupervised recurrent neural network (PixelRNN) trained to predict video sequences. We previously found that such networks reproduce several key gloss perception phenomena, including the ‘sticky-reflection’ effect (Doerschner et al., 2011, Current Biology), wherein reflections that move with the surface (instead of sliding across it) appear like matte texture markings. We generated 8,000 20-frame movies of objects with diverse appearances and motions by varying the shape, glossiness, soft-body properties (including rigid objects), illumination environments, texture maps, and various rotational directions and speeds. After training, the PixelRNN could synthesize accurate video predictions up to 10 frames into the future. T-SNE visualization of the embedding of new stimuli in the network’s internal representation revealed a clear clustering and disentanglement of the different object types by the network, as confirmed by logistic linear classification according to their surface glossiness and deformability. Over the course of just the first three frames, classification of softness increased dramatically from chance to 99% accuracy. When participants compared the glossiness and rigidity of pairs of stimuli from the test set, we found that human judgements correlated with predictions derived from the embedding of stimuli in the network’s representation. These findings demonstrate that unsupervised predictive learning can disentangle softness and glossiness properties of objects, much like humans, without any explicit training about the distal object properties.
