Because of attentional limitations, the human visual system can process for awareness and response only a fraction input received. Lesion functional imaging studies have identified frontal, temporal, parietal areas as playing major role in control processing, but very little is known about how these interact to form dynamic network. We hypothesized that network communicates by means neural phase synchronization, we used magnetoencephalography study transient long-range interarea coupling...
We set out to distinguish level 1 (VPT-1) and 2 (VPT-2) perspective taking with respect the embodied nature of underlying processes as well investigate their dependence or independence response modality (motor vs. verbal). While VPT-1 reflects understanding what lies within someone else's line sight, VPT-2 involves mentally adopting spatial point view. Perspective is a high-level conscious deliberate mental transformation that crucially placed at convergence perception, imagery,...

Abstract We re-analysed visuo-spatial perspective taking data from CitationKessler and Thomson (2010) plus a previously unpublished pilot with respect to individual- sex differences in embodied processing (defined as body-posture congruence effects). found that so-called 'systemisers' (males/low-social-skills) showed weaker embodiment than 'embodiers' (females/high-social-skills). conclude either have difficulties or, alternatively, they strategic advantage selecting different mechanisms or...
Abstract TEST is a novel taxonomy of knowledge representations based on three distinct hierarchically organized representational features: Tropism, Embodiment , and Situatedness. Tropic features reflect constraints the physical world agent's ability to form, reactivate, enrich embodied (i.e., resulting from bodily constraints) conceptual embedded in situated contexts. The proposed hierarchy entails that can, principle, have tropic without necessarily having and/or features. On other hand,...
Autism Spectrum Disorder is often accompanied by sensory symptoms. Using magnetoencephalography to measure gamma and alpha band cortical activity in affected individuals, Seymour et al. corroborate the hypothesis that aberrant processing linked atypical functional connectivity within between areas of visual system.
There is increasing interest in understanding how the phase and amplitude of distinct neural oscillations might interact to support dynamic communication within brain. In particular, previous work has demonstrated a coupling between low frequency (or power) high during certain tasks, termed (PAC). For instance, visual processing humans, PAC been reliably observed ongoing alpha (8-13Hz) gamma-band (>40Hz) activity. However, application metrics electrophysiological data can be challenging due...
Abstract Background Auditory steady state responses (ASSRs) are elicited by clicktrains or amplitude-modulated tones, which entrain auditory cortex at their specific modulation rate. Previous research has reported reductions in ASSRs 40 Hz for autism spectrum disorder (ASD) participants and first-degree relatives of people diagnosed with ASD (Mol Autism. 2011;2:11, Biol Psychiatry. 2007;62:192–197). Methods Using a 1.5 s-long clicktrain stimulus, designed to elicit an ASSR Hz, this study...
A prominent theory claims that the right temporoparietal junction (rTPJ) is especially associated with embodied processes relevant to perspective-taking. In present study, we use high-definition transcranial direct current stimulation provide evidence rTPJ causally underpinning Eighty-eight young human adults were stratified receive either or dorsomedial PFC anodal in a sham-controlled, double-blind, repeated-measures design. Perspective-tracking (line-of-sight) and perspective-taking...
During search of the environment, inhibition return (IOR) attention to already-examined information ensures that target will ultimately be detected. Until now, was assumed support during one processing episode. However, in some situations may have completed long after it begun. We therefore propose can associated with an episode encoded into memory such later retrieval reinstates inhibitory and encourages examination new information. In two experiments which drawn face stimuli exogenous cue,...
Visual attention studies often rely on response time measures to show the impact of attentional facilitation and inhibition. Here we extend investigation effects behavior that prior states associated with unfamiliar faces can influence subsequent social-emotional judgments about those faces. Participants were shown pairs face images asked withhold a if transparent stop-signal cue appeared over one This served associate cued an inhibitory state. Later, when make choices these pairs,...
Humans are especially good at taking another's perspective—representing what others might be thinking or experiencing. This "mentalizing" capacity is apparent in everyday human interactions and conversations. We investigated its neural basis using magnetoencephalography. focused on whether mentalizing was engaged spontaneously routinely to understand an utterance's meaning largely on-demand, restore "common ground" when expectations were violated. Participants conversed with 1 of 2...
Being able to judge another person's visuo-spatial perspective is an essential social skill, hence we investigated the generalizability of involved mechanisms across cultures and genders. Developmental, cross-species, our own previous research suggest that two different forms taking can be distinguished, which are subserved by distinct mechanisms. The simpler form relies on inferring another's line-of-sight, whereas more complex depends embodied transformation into other's orientation in a...
Abstract Embodied processing is crucial for visual perspective taking (VPT), with evidence from non-invasive transcranial direct current stimulation (tDCS) suggesting a causal role of the right temporoparietal junction (rTPJ). However, it not known whether such embodied factors are maintained in older adults or rTPJ-tDCS has comparable effects advanced age. We employed balanced and sham-tDCS controlled, double-blinded, cross-over design, including two randomized experimental groups healthy...
To identify the neurocognitive mechanisms underpinning social difficulties that characterize autism, we performed functional magnetic resonance imaging on pairs of autistic and non-autistic adults simultaneously whilst they interacted with one another iterated Ultimatum Game (iUG)-an interactive task emulates reciprocal characteristic naturalistic interpersonal exchanges. Two age-matched sets male-male dyads were investigated: 16 comprised an Responder a Proposer, 19 Proposer. Players'...
The article explores the possibilities of formalizing and explaining mechanisms that support spatial social perspective alignment sustained over duration a interaction. basic proposed principle is in contexts for sensorimotor transformations multisensory integration (learn to) incorporate information relative to other actor(s), similar "re-calibration" visual receptive fields response repeated tool use. This process aligns or merges co-actors' representations creates "Shared Action Space"...
