摘要

$$\rightleftharpoonup{xx}$$ $$\longleftharp{xx}$$, $$\longrightharp{xx}$$,

Functional near-infrared spectroscopy (fNIRS) is a noninvasive method particularly suitable for measuring cerebral cortex activation in multiple subjects, which is relevant for studying group interpersonal interactions in ecological settings. Although many fNIRS systems technically offer the possibility to monitor more than two individuals simultaneously, establishing easy-to-implement setup procedures and reliable paradigms to track hemodynamic and behavioral responses in group interaction is still required. The present protocol combines fNIRS and video-based observation to measure interpersonal synchronization in quartets during a cooperative task.This protocol provides practical recommendations for data acquisition and paradigm design, as well as guiding principles for an illustrative data analysis example. The procedure is designed to assess differences in brain and behavior interpersonal responses between social and non-social conditions inspired by a well-known ice-breaker activity, the Collaborative Face Drawing Task. The described procedures can guide future studies to adapt group naturalistic social interaction activities to the fNIRS environment.

引言

$$\rightleftharpoonup{xx}$$ $$\longleftharp{xx}$$, $$\longrightharp{xx}$$,

Interpersonal interaction behavior is an important component of the process of connecting and creating empathic bonds. Previous research indicates that this behavior can be expressed in the occurrence of synchronicity, when biological and behavioral signals align during social contact. Evidence shows that synchronicity can occur between people interacting for the first time1,2,3. Most studies on social interactions and their underlying neural mechanisms use a single person or second person approach2,4<....

方案

$$\rightleftharpoonup{xx}$$ $$\longleftharp{xx}$$, $$\longrightharp{xx}$$,

The methodology was approved by the Hospital Israelita Albert Einstein (HIAE) Ethics Committee and is based on a procedure for collecting neural data (fNIRS), as well as gaze behavior data, with young adults during a collaborative drawing experience. All collected data were managed on the Redcap platform (see Table of Materials). The project was audited by the Scientific Integrity Committee of the Hospital Israelita Albert Einstein (HIAE). Young adults, 18-30 years old, were selected as subjects for the present study. Written informed consent was obtained from all participants.

结果

$$\rightleftharpoonup{xx}$$ $$\longleftharp{xx}$$, $$\longrightharp{xx}$$,

The protocol was applied to a quartet composed of young women (24-27 years old), all of them students on postgraduate programs (Hospital Israelita Albert Einstein, São Paulo, Brasil), with master's or doctorate level education. All participants were right-handed, and only one reported having previous drawing experience. No participants had a reported history of neurological disorders.

For the scales and psychological test results, two participants (2 and 4) showed high scores for anxiety (17 a.......

讨论

$$\rightleftharpoonup{xx}$$ $$\longleftharp{xx}$$, $$\longrightharp{xx}$$,

This study aimed to create a protocol using hyperscanning on four brains concurrently under naturalistic conditions. The experimental paradigm used different drawing tasks and the correlation of multiple outcome measures, drawing metrics, behaviors, and brain signals. The critical steps within this protocol are the consideration of the challenges arising from its high complexity and the maintenance of its ecological and naturalistic conditions.

Video observation was key to this study. It .......
