The building façade has considerable effects on the aesthetic experience of observers. However, the experience may differ depending on the observers' expertise. This study was conducted to explore the impact of expertise on preference, visual exploration, and cognitive experience during the aesthetic judgment of designed façades. For this purpose, we developed a paradigm in two separate parts: aesthetic judgment (AJ) and eye movement recording (EMR). Thirty-eight participants participated in this experiment in two groups (21 experts/17 nonexperts). The results revealed significant differences between the two groups in terms of the type and number of preferred façades, as well as eye movement indicators. In addition, based on judgment reaction time and fixation duration as proxy measures of cognitive experience, it was found that expertise might be correlated with cognitive load and task demand. The findings indicate the importance of façades for both groups and suggest that their physical attributes could be effectively manipulated to impact aesthetic experiences in relation to architectural designs.

Private, subjective beliefs about uncertainty have been found to have idiosyncratic computational and neural substrates yet, humans share such beliefs seamlessly and cooperate successfully. Bringing together decision making under uncertainty and interpersonal alignment in communication, in a discovery plus pre-registered replication design, we examined the neuro-computational basis of the relationship between privately-held and socially-shared uncertainty. Examining confidence-speed-accuracy trade-off in uncertainty-ridden perceptual decisions under social vs isolated context, we found that shared (i.e., reported confidence) and subjective (inferred from pupillometry) uncertainty dynamically followed social information. An attractor neural network model incorporating social information as top-down additive input captured the observed behaviour and spontaneously demonstrated the emergence of social alignment in virtual dyadic simulations. Electroencephalography showed that social exchange of confidence modulated the neural signature of perceptual evidence accumulation in the central parietal cortex and produced a sustained top-down flow of information from prefrontal to parietal cortex. Our findings offer a neural population model for interpersonal alignment of shared beliefs.
