安全基地启动及其脑机制

近几年,安全基地启动已成为拓展依恋理论的重要实验方法。安全启动能够改善情绪及情绪调节策略、增进人际关系、促进自我实现和利他等。安全启动下,研究者得以考察成人依恋与母婴依恋的神经基础及它们之间的区别与联系。该文分析了安全启动实验的不足,如生态效度和重复率不高,应用范围局限,缺乏启动效应持续性的研究等。未来的安全启动研究应突破现有实验室情境研究局限,拓展应用领域,加强对其心理机制与神经机制的探讨等。

论朱熹对"继善成性"说的规范

"继善成性"是易学哲学的重要问题.朱熹解释"继善成性"总体上不是为字义的通顺,而在为他的理学本体论作论证.理上气下的基本原则通过易学的语言进一步得到贯彻.善与性、天与人、未发与已发、天理流行与人物成性等,虽也体现了天人之间的密切关联,但又不能将一般天理与已具形质的人性混淆起来."继善成性"说的优长,就在于它将由天至人的生成序列,解释为一个以天道为本而构筑本性的思辨逻辑,同时兼顾个体形质生成带来的特殊性.而本性只是"存"而非"成",以卫护本然之性纯善无恶的假定.     

Territorial gain dynamics regulates success in attacking sub-phases of team sports

Background and objective

Field invasion games, such as rugby union, can be conceptualised as dynamic social systems in which the agents continuously interact to contest ball possession and territorial gain. Accordingly, this study aimed to identify the collective system dynamics of rugby union phases-of-play near the try line by investigating whether ball displacement trajectory on the playing field provides insights on successful team performance.

Methods

Five rugby union matches were videotaped involving teams at a national league performance level. From these matches, 22 second phases-of-play were selected and digitized for analysis. The variable “distance gained” was investigated as a potential coordination variable describing functional coordination between players and teams. This variable concerned the distance between ball initial position and ball current position over time and was used to define the degree of territory gained by an attacking team.

Results

Analysis of distance gained dynamics in attacking sub-phases demonstrated the intermittent character of rugby union performers displacement trajectories on the playing field. Amplitude of ball movements was revealed as a distinguishing feature related to attacking effectiveness. Successful attacking phases displayed lower distances of positional retreat, with the maximum retreat distance achieved sooner in successful compared to unsuccessful phases-of-play. Autocorrelation and ApEn analyses suggested low system variability within time series data concerning both performance outcomes. However, evidence of less regularity and more complexity was found in unsuccessful phases-of-play.

Conclusion

Results suggested that distance gained dynamics manifests a characteristic collective behaviour pattern that captures the macroscopic functional order of multi-player attack–defence systems in team sports like rugby union.     

矛盾态度心理机制的理论模型述评

矛盾态度已发展为态度研究领域一个重要方面,在理论和实证研究都取得重要进展,但是对矛盾态度心理机制的探究还处于滞后的态势。本研究试图对矛盾态度心理机制研究做一个较系统的梳理,引入对象与评价的联结模型、态度元认知模型、重复加工模型和表征分布式联结主义模型等四种态度理论模型有关解析,并结合相关实证研究予以阐述和评价。未来该领域的研究应加强矛盾态度研究的元分析、各研究之间的沟通和整合、实证研究范畴的拓展、新技术的引入等问题的研究。     

Neural mechanisms involved in the oral representation of percussion music: An fMRI study

Numerous music cultures use nonsense syllables to represent percussive sounds. Covert reciting of these syllable sequences along with percussion music aids active listeners in keeping track of music. Owing to the acoustic dissimilarity between the representative syllables and the referent percussive sounds, associative learning is necessary for the oral representation of percussion music. We used functional magnetic resonance imaging (fMRI) to explore the neural processes underlying oral rehearsals of music. There were four music conditions in the experiment: (1) passive listening to unlearned percussion music, (2) active listening to learned percussion music, (3) active listening to the syllable representation of (2), and (4) active listening to learned melodic music. Our results specified two neural substrates of the association mechanisms involved in the oral representation of percussion music. First, information integration of heard sounds and the auditory consequences of subvocal rehearsals may engage the right planum temporale during active listening to percussion music. Second, mapping heard sounds to articulatory and laryngeal gestures may engage the left middle premotor cortex.
