How Face Mask Wearing Affects the Sense of Self: Breathing as a Case of Disrupted Bodily Self-Consciousness
No full textThis pioneer study focuses on the feedback effect that the face mask has on its wearer’s sense of Self (i.e. bodily Self-consciousness) caused by its multisensorial components and affordances which are taken into account from a first-person perspective approach. On the grounds of enactivism and Material Engagement Theory, we run qualitative semi-structured interviews recruiting 48 participants: 24 people had no experience using lower face coverings before COVID-19 pandemic (February 2020) and 24 people were hospital workers with such prior experience. Results show that face mask wearing dramatically updates bodily Self-consciousness retroacting on breathing experience, with differences between the two groups. This is consistent with evidence showing that breathing is “transparent” unless bodily, environmental, and/or emotional changes arouse a situated awareness of it. We conclude that the face mask performs a retroactive effect, which we explained as due to a “material performative agency” that significantly modifies the standard balance between the transparency and the opacity of our bodily Self-consciousness

Comprehending body language and mimics: An ERP and neuroimaging study on Italian actors and viewers
Full text linkIn this study, the neural mechanism subserving the ability to understand people's emotional and mental states by observing their body language (facial expression, body posture and mimics) was investigated in healthy volunteers. ERPs were recorded in 30 Italian University students while they evaluated 280 pictures of highly ecological displays of emotional body language that were acted out by 8 male and female Italian actors. Pictures were briefly flashed and preceded by short verbal descriptions (e.g., "What a bore!") that were incongruent half of the time (e.g., a picture of a very attentive and concentrated person shown after the previous example verbal description). ERP data and source reconstruction indicated that the first recognition of incongruent body language occurred 300 ms post-stimulus. swLORETA performed on the N400 identified the strongest generators of this effect in the right rectal gyrus (BA11) of the ventromedial orbitofrontal cortex, the bilateral uncus (limbic system) and the cingulate cortex, the cortical areas devoted to face and body processing (STS, FFA EBA) and the premotor cortex (BA6), which is involved in action understanding. These results indicate that face and body mimics undergo a prioritized processing that is mostly represented in the affective brain and is rapidly compared with verbal information. This process is likely able to regulate social interactions by providing on-line information about the sincerity and trustfulness of others. © 2014 Proverbio et al
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
The effect of Surround sound on embodiment and sense of presence in cinematic experience: a behavioral and HD-EEG study
No full textAlthough many studies have investigated spectators’ cinematic experience,
only a few of them explored the neurophysiological correlates of the sense
of presence evoked by the spatial characteristics of audio delivery devices.
Nevertheless, nowadays both the industrial and the consumer markets have
been saturated by some forms of spatial audio format that enrich the audio-
visual cinematic experience, reducing the gap between the real and the digitally
mediated world. The increase in the immersive capabilities corresponds to the
instauration of both the sense of presence and the psychological sense of
being in the virtual environment and also embodied simulation mechanisms.
While it is well-known that these mechanisms can be activated in the real
world, it is hypothesized that they may be elicited even in a virtual acoustic
spatial environment and could be modulated by the acoustic spatialization cues
reproduced by sound systems. Hence, the present study aims to investigate
the neural basis of the sense of presence evoked by different forms of
mediation by testing different acoustic space sound delivery (Presentation modes:
Monophonic, Stereo, and Surround). To these aims, a behavioral investigation and
a high-density electroencephalographic (HD-EEG) study have been developed.
A large set of ecological and heterogeneous stimuli extracted from feature films
were used. Furthermore, participants were selected following the generalized
listener selection procedure. We found a significantly higher event-related
desynchronization (ERD) in the Surround Presentation mode when compared to
the Monophonic Presentation mode both in Alpha and Low-Beta centro-parietal
clusters. We discuss this result as an index of embodied simulation mechanisms
that could be considered as a possible neurophysiological correlation of the
instauration of the sense of presence
