OBJECTIVE. Reducing radiation exposure through the use of low-dose protocols during cerebral endovascular procedures is recommended, but evaluation of the impact on the procedure itself is difficult and subjective. A workflow task analysis could provide an objective comparison of two different radiation exposure protocols. SUBJECTS AND METHODS. Twenty endovascular aneurysm ...

In spite of the remarkable progress made in the burgeoning field of social neuroscience, the neural mechanisms that underlie social encounters are only beginning to be studied and could - paradoxically - be seen as representing the "dark matter" of social neuroscience. Recent conceptual and empirical developments consistently indicate the need for investigations that ...

This commentary situates the second person account within a broader framework of ecological validity for experimental paradigms in social cognitive neuroscience. It then considers how individual differences at psychological and genetic levels can be integrated within the proposed framework.
Cummins Fred - - 2013
The target article's approach is applauded, but it is suggested that the "dark matter" may be much larger than even the current authors suspect. Cartesian and mechanistic assumptions infuse not only the discipline of cognitive psychology, but all societal accounts of the person. A switch to dynamical accounts in which ...

As there is "dark matter" in the neuroscience of individuals engaged in dynamic interactions, similar dark matter is present in the domain of interaction between humans and cognitive robots. Progress in second-person neuroscience will contribute to the development of robotic cognitive systems, and such developed robotic systems will be used ...

Through the mental alignment that sustains social interactions, the minds of individuals are shared. One interpretation of shared intentionality involves the ability of individuals to perceive features of the action scene from the perspective of the group (the "we-mode"). This first-person plural approach in social cognition is distinct from and ...

A second-person perspective in neuroscience is particularly appropriate for the study of communication. We describe how the investigation of joint language tasks can contribute to our understanding of the mechanisms underlying interaction.
Lewis Charlie - - 2013
Schilbach et al.'s model assumes that the ability to "experience" minds is already present in human infants and therefore falls foul of the very intellectualist problems it attempts to avoid. We propose an alternative relational, action-based account, which attempts to grasp how the individual's construction of knowledge develops within interactions.
Longo Matthew R - - 2013
Schilbach et al. contrast second-person and third-person approaches to social neuroscience. We discuss relations between second-person and first-person approaches, arguing that they cannot be studied in isolation. Contingency is central for converging first- and second-person approaches. Studies of embodiment show how contingencies scaffold first-person perspective and how the transition from ...

Schilbach et al. contribute to neuroscience methodology through drawing on insights from the second-person approach. We suggest that they could further contribute to social neuroscience by more fully spelling out the ways in which a second-person approach to the nature and origin of thinking could transform neuroscience.
Simpson Elizabeth Ann - - 2013
Based on mirror neurons' properties, viewers are emotionally engaged when observing others - even when not actively interacting; therefore, characterizing non-participatory action-viewing as isolated may be misleading. Instead, we propose a continuum of socio-emotional engagement. We also highlight recent developmental work that uses a second-person perspective, investigating behavioral, physiological, and neural activity ...

Language is a social act. We have previously argued that language remains embedded in sociality because the motivation to communicate exists only within a social context. Schilbach et al. underscore the importance of studying linguistic behavior from within the motivated, socially interactive frame in which it is learnt and used, ...

Psychopathy is a personality disorder associated with a profound lack of empathy. Neuroscientists have associated empathy and its interindividual variation with how strongly participants activate brain regions involved in their own actions, emotions and sensations while viewing those of others. Here we compared brain activity of 18 psychopathic offenders with ...
