“…Additional findings report that the left hemisphere is more involved in processing spatial relations, while the activity of the right parietal lobe relates to coordinate spatial relations (Baciu et al, 1999 ; Suegami and Laeng, 2013 ). Interestingly, Cela-Conde et al ( 2009 ) show that in women there is a lateralized activity in the left parietal areas during the observation of stimuli rated as beautiful.…”

Nowadays there is the hope that neuroscientific findings will contribute to the improvement of building design in order to create environments which satisfy man's demands. This can be achieved through the understanding of neurophysiological correlates of architectural perception. To this aim, the electroencephalographic (EEG) signals of 12 healthy subjects were recorded during the perception of three immersive virtual reality environments (VEs). Afterwards, participants were asked to describe their experience in terms of Familiarity, Novelty, Comfort, Pleasantness, Arousal, and Presence using a rating scale from 1 to 9. These perceptual dimensions are hypothesized to influence the pattern of cerebral spectral activity, while Presence is used to assess the realism of the virtual stimulation. Hence, the collected scores were used to analyze the Power Spectral Density (PSD) of the EEG for each behavioral dimension in the theta, alpha and mu bands by means of time-frequency analysis and topographic statistical maps. Analysis of Presence resulted in the activation of the frontal-midline theta, indicating the involvement of sensorimotor integration mechanisms when subjects expressed to feel more present in the VEs. Similar patterns also characterized the experience of familiar and comfortable VEs. In addition, pleasant VEs increased the theta power across visuomotor circuits and activated the alpha band in areas devoted to visuospatial exploration and processing of categorical spatial relations. Finally, the de-synchronization of the mu rhythm described the perception of pleasant and comfortable VEs, showing the involvement of left motor areas and embodied mechanisms for environment appreciation. Overall, these results show the possibility to measure EEG correlates of architectural perception involving the cerebral circuits of sensorimotor integration, spatial navigation, and embodiment. These observations can help testing architectural hypotheses in order to design environments matching the changing needs of humans.

“…The supramarginal gyrus is a parietal area that has been shown to be involved in phonological word processing [23], but also visual word recognition [68]. Stoeckel et al [70] used TMS to investigate the functional specificity of the supramarginal gyrus during reading. They could show that stimulation of this area facilitated reaction times for both a phonological and a semantic task, concluding that the supramarginal gyrus is involved in visual word recognition independent of specific task demands.…”

“…Furthermore, there is evidence for lateralised category effects that seem unrelated to language. Lateralised category effects with stimuli other than colour can occur independent of verbal labelling and language (Holmes & Wolff, 2012;Suegami & Laeng, 2013;.…”

“…Opposite lateralised category effects in the left visual field occurred in observers who, presumably, lack language processing (Franklin et al, 2008a;Paluy et al, 2011). Studies that tested lateralised category effects with stimuli other than colour found that these effects can be produced independent of verbal labelling and language (Holmes & Wolff, 2012;Suegami & Laeng, 2013;. Hence, the observation of category effects cannot be taken as evidence for the involvement of language, either.…”

We review research on the neural correlates of colour categories, and categorical responses in preverbal infants and animals. Our aim was to address the question of the functional segregation of colour categories from colour perception and colour language, i.e. whether or not colour categorisation shares processing resources with language and perception. Together, the reviewed findings suggest that colour categorisation often involves automatic language processing, but it can also occur in the absence of language or colour naming, as suggested by research on brain-damaged patients, preverbal infants, and non-human animals. Furthermore, there is no compelling evidence coming from human neuroimaging and neuropsychological studies, or from animal studies, that categorisation is inherent to colour perception. Instead, colour categorisation might simply build upon the continuous perception of colour and may interact with perception through the direction of attention to colour differences that are relevant to categorisation. Altogether, the reviewed evidence does not seem to offer a straightforward account of the origin of lexical colour categories. We suggest that future research in all areas (1) requires methodological improvements, in particular in stimulus control, (2) should overcome the universalist-realist debate and go beyond a simple contrast between perception and language, and (3) should consider the link between object colours and colour categories to establish both evolutionary and developmental continuity between categorical responses in animals, infants and adult humans.
