Laboratory of functional neuroelectrical imaging and brain–computer interfacing at Fondazione Santa Lucia

The laboratory of functional neuroelectrical imaging and brain–computer interfacing at Fondazione Santa Lucia is based on the joint work of researchers with a bioengineering and clinical neurophysiology background. The activity is mainly devoted to two aims: the non-invasive investigation of the motor cortical function under physiological and pathological conditions, through the development of advanced processing methods of the electroencephalographic signals; the development of a real-time EEG-based brain–computer interface (BCI) and the study of its use as an aid to enhance (or even to allow) the functional independence of persons with different degrees of motor disability.     

Communicative factors,conflict progression,and use of reconciliatory strategies in pre‐school boys‐a series of random events or a sequential process?

Affiliative interactions between former opponents soon after a conflict, in non‐human primates and pre‐school children, have been documented to be followed by a reduction of future aggression and stress reactions, and to promote tolerance between individuals. The phenomenon has, therefore, been called reconciliation. Studies of non‐human primates have shown that the conflict cause can influence the reconciliatory outcome, and whether the aggressor or the victim of the aggression is more likely to take the initiative to reconcile, can differ between species. Few studies in pre‐school children have addressed how factors preceding the post‐conflict period, such as social interactions before the conflict outbreak, or the cause of the conflict, may be related to the likelihood of reconciliation, conflict progression, and conflict outcome in the form of possible continuation or initiation of interactions. Twenty boys were video‐recorded during free‐play at six pre‐schools. The existence of social interaction between the opponents in the upcoming conflict was examined in the pre‐conflict period. The observed causes of conflict were determined and classified into five categories. The affiliative behaviors identified in the post‐conflict period were classified into six categories. Finally, whether or not conflicts were followed by communicative exchanges in the succeeding non‐conflict period was documented. The results revealed that the cause of the conflict is associated with whether opponents had established social interaction prior to conflict in the pre‐conflict period. Acceptance rates (for the various categories of affiliative behaviors) appeared to differ. A non‐random pattern of conflict progression was apparent, suggesting the conflict cause was related to the category of reconciliatory strategy shown by the individuals. The aggressor and the victim initiated reconciliation at similar rates, with the exception of verbal apologies, which were initiated most often by the aggressor. Finally, the data also showed that higher frequencies of social interaction between former opponents in the succeeding non‐conflict period were associated both with whether or not social interaction had occurred in the pre‐conflict period, and whether or not the conflict was reconciled. In conclusion, communicative factors preceding conflicts, and conflict cause, are distinctively correlated with both the use and the outcome of post‐conflict affiliation in pre‐school boys. Aggr.

空间情境模型的更新：认知方式的影响

采用前照应解决(anaphora resolution)与学习探测相结合的实验范式以及移动窗口技术探讨不同认知方式个体的空间情境模型更新能力的差异。实验1发现, 场依存性被试在高预见性条件下表现出空间距离效应, 低预见性条件下则没有; 而场独立性被试刚好相反。实验2通过在关键句中提示路径房间的一个物品深入探讨更新过程中不同认知方式个体更新模式的差异, 结果发现, 两类被试在低预见性记叙文中都表现出了明显的空间距离效应。这表明, 场独立性个体的空间情境模型更新能力高于场依存性个体的更新能力。     

初级视觉皮层在注意振荡中的作用

注意离散性是注意间歇性地采集外界信息的特性, 这种特性在行为中的表现被称为注意振荡。尽管有研究使用经典的线索靶子范式和视觉搜索范式发现行为数据中存在注意振荡, 证明了注意是离散的, 但其相应的神经机制, 即注意离散性与哪些脑区有关, 尚不明确。研究采用高时间分辨率的线索靶子范式和双眼分视技术, 基于人眼视觉通路的解剖学特性, 比较了线索靶子出现在双眼(实验1)、同眼和异眼(实验2)条件下的注意振荡, 考察初级视觉皮层对注意振荡的影响。结果发现：1)双眼分视会对注意振荡发生的频段产生影响, 非双眼分视条件下, 注意振荡出现在低频(2 Hz和8 Hz)。而双眼分视条件下, 注意振荡则出现在更高的频段(12.5 Hz)。2)无论线索靶子出现在同眼还是异眼, 注意振荡的频段无显著差异。结果表明V1区双眼视觉通路或者更高级的视觉区可能参与注意振荡, 为探明注意振荡的神经机制提供了重要的行为学证据。     

Conflict resolution and procedural fairness in Japanese work organizations

Abstract: The purpose of this study was to examine short‐term and long‐term effects of perceived fairness, and to examine relational factors’ effects of procedural fairness in organizational conflicts between employees and supervisors among the Japanese. We asked 154 Japanese employees working in companies to rate their perception of conflicts as well as attitudes towards their own companies. We found that both perception of procedural and distributive fairness produced short‐term effects (satisfaction with outcome of conflicts) and long‐term effects (positive organizational attitudes). Perceived procedural fairness was increased by appropriate treatment of the supervisors, but our prediction that this effect would be moderated by the employees’ identification with organizations was not supported.     

In Search of Bandhood: Consultation with Original Music Groups

Original music groups present a unique and under-explored example of self-initiated task groups. The intragroup life and negotiation of creative differences in three diverse original music groups from New York City were explored. Establishment of a shared group ideology and management of organizational tensions, identified in Murnighan and Conlon's study of professional string quartets, appeared central in the bands' cohesion. The role of group therapist, as a band consultant, was examined.     

Initial goals,goal trajectories,and changes in perceived resolvability during serial arguments

This study examined how dyadic patterns of goal importance during a serial argument interaction predict changes in perceptions of argument resolvability over the course of a specific episode. Seventy romantic couples engaged in a 7‐min discussion of a current serial argument and used a video‐assisted recall method to report their goals at each minute. Although arguers' initial goals did not predict changes in perceptions of resolvability, increases in a partner's endorsement of partner‐identity goals predicted increases in individuals' own perceptions of resolvability. Conversely, increases in a partner's endorsement of self‐identity goals predicted declines in individuals' perceived resolvability. Results suggest that trajectories of identity‐focused goals during serial argument episodes may shape the progress of argument perceptions toward or away from resolvability.     

Exploring Conflict Resolution and Psychological Abuse Across Romantic Relationships

Although strengthening skills is recommended to improve the effectiveness of programs to prevent dating violence, little research has analyzed how conflict resolution strategies relate to victimization/perpetration trajectories. This study explores retrospectively self-reported conflict resolution strategies (positive problem-solving, engagement, and withdrawal) across 2 romantic relationships, paying special attention to possible changes. Participants were 309 college students who had been involved in 1, 2, or no abusive relationships. Based on these experiences, they were first classified into 4 groups according to their psychological victimization (non-victimized, pre-victimized, newly-victimized, and re-victimized) in each of their 2 relationships. Subsequently, they were also classified into 4 different groups according to their perpetration (non-perpetrators, pre-perpetrators, new perpetrators, and re-perpetrators). Changes in conflict resolution strategies were self-reported by both the victims and the perpetrators with a single abusive relationship, whereas persistence was detected in those involved in either 2 abusive relationships (re-victimized and re-perpetrators) or none at all. The results can help prevent dating violence across relationships and its negative consequences for health.
