Der Einfluß somatischer und psychosozialer Faktoren auf Entstehung und Verlauf chronisch-entzündlicher Darmerkrankungen

Zusammenfassung Chronisch-entzündliche Darmerkrankungen (Morbus Crohn, Colitis ulcerosa) werden traditionellerweise zu den psychosomatischen Erkrankungen gez?hlt. In jüngster Zeit wurde diese Zuordnung aber mehrfach in Frage gestellt; zugleich wurden biomedizinische Faktoren beschrieben, die in der Entstehung und im Verlauf der Erkrankungen eine Rolle spielen k?nnten. Die vorliegende übersichtsarbeit hat das Ziel, den aktuellen Stand der biomedizinischen und psychosomatischen Forschung zur ?tiologie und Verlaufsgestaltung bei chronisch-entzündlichen Darmerkrankungen darzustellen und unter methodischen Gesichtspunkten kritisch zu bewerten. Forschungsergebnisse zu folgenden Themenbereichen werden referiert: Epidemiologie; soziodemographische Merkmale; Genetik; di?tetische Faktoren und Zigarettenrauchen; Medikamente; Permeabilit?tsst?rung der Darmepithelien; immunologische Faktoren; mikrobiologische Faktoren; psychiatrische St?rung; emotionale Symptomatik, Pers?nlichkeitsmerkmale; kritische Lebensereignisse und psychosozialer Stre?; Lebensqualit?t und Krankheitsbew?ltigung.      

The problem of moral absolutes in the ethics of Vladimir Solov'ëv

Conclusion Moral absolutes were perceived, by Solov'?v, in a dual manner: a) from the side of content, of psychology, as when we speak of feelings, emotions, etc.; and b) under a formal aspect, as “ideas,” i.e. logically. Neither of these can be treated without relating to moral absolutes astrue, and without a rationalbelief in their truth, a truth that cannot be logically proved. In my opinion, our time has become keenly aware of the universally human value of Vladimir Solov'?v's ethics, of its humanist nature, oriented towards the everyday and the ideal tasks of man, and of the concrete direction of his philosophy of “practical idealism”.     

Die Bindungstheorie und ihre Relevanz für die Psychotherapie

Zusammenfassung Die ursprünglich von John Bowlby entwickelte Bindungstheorie gewinnt zunehmend an Relevanz im Bereich der Psychotherapie(forschung). Diese übersicht beginnt mit einer Kl?rung der zentralen Begriffe und Annahmen dieser Theorie und fa?t einige Befunde zur Entwicklung und den Korrelaten von Bindung zusammen, die vornehmlich aus entwicklungspsychologischen Untersuchungen stammen. übertragen auf Erwachsene, bedürfen die Konzepte der Bindungstheorie einer Revision, die in dieser Arbeit skizziert wird. Schlie?lich werden auf dieser Basis einige heute übliche Methoden zur Erfassung von Bindungsstilen und Bindungsverhalten im Erwachsenenalter dargestellt, die bei Untersuchungen im klinischen Feld (Inhalt des 2. Teils der übersichtsarbeit) eine wichtige Rolle spielen.      

Serial learning in the pigeon.

Three pigeons learned to peck four colors in a particular sequence, regardless of how these colors were positioned on four response keys and without feedback following each response. This demonstrates that serial learning is possible in subprimate animals.     

Antiwomen But Proquota: Disaggregating Sexism and Support for Gender Quota Policies

Previous research on support for gender quotas focuses on attitudes toward gender equality and government intervention as explanations. We argue the role of attitudes toward women in understanding support for policies aiming to increase the presence of women in politics is ambivalent—both hostile and benevolent forms of sexism contribute in understanding support, albeit in different ways. Using original data from a survey conducted on a probability-based sample of Australian respondents, our findings demonstrate that hostile sexists are more likely to oppose increasing of women's presence in politics through the adoption of gender quotas. Benevolent sexists, on the other hand, are more likely to support these policies than respondents exhibiting low levels of benevolent sexism. We argue this is because benevolent sexism holds that women are pure and need protection; they do not have what it takes to succeed in politics without the assistance of quotas. Finally, we show that while women are more likely to support quotas, ambivalent sexism has the same relationship with support among both women and men. These findings suggest that aggregate levels of public support for gender quotas do not necessarily represent greater acceptance of gender equality generally.     

Can infants use video to update mental representations of absent objects?

Before their second birthday, infants can update their knowledge based on what someone tells them, but can they do so based on what a video shows them? The current study explored whether infants can update their representation of an absent object’s properties after seeing a video of something happening to it, following seminal work showing that they can update their representation after being told about something happening to it (Ganea et al., 2007). It thus adapted an existing paradigm for testing infants’ understanding of references to absent objects (using language) to investigate a different symbolic medium (video). Twenty-two-month-olds first played with a toy and later saw on video that the toy underwent a change in state while they were out of the room. Infants in the current study did not subsequently identify the toy based on this new information, whereas those in previous research did. Infants this age thus appear less likely to update their representation of an absent object’s properties using video than using language. This result is consistent with the possibility that infants may understand the representational function of symbolic objects later in development than they understand the representational function of language. It also aligns with evidence of the video deficit in which infants learn less effectively from video than from firsthand experience.     

自身得失对朋友博弈结果评价的影响：来自ERPs的证据

本研究通过经典的金钱博弈任务, 以FRN和P300为反应指标, 探讨了自身获益或损失对朋友结果评价分别会产生何种影响, 以及这种影响模式是如何受到个体自我建构方式调节的。结果发现, 在自身获益条件下, 观看朋友损益之间的FRN和P300差异不再存在; 在自身损失条件下, 虽然观看朋友输赢之间的P300差异消失了, 但FRN差异依然显著。不仅如此, 无论自身得失, 独立型自我建构启动组在观看朋友损益上的FRN差异均不再显著, 但在自身获益后看到朋友损失能激发更强的P300波幅。本研究结果表明：(1) 对朋友的结果评价模式并非固定不变, 而是会随个体自身所处得失境遇的不同而有所区别; (2) 相对于互依型自我建构启动组, 独立型自我建构启动组在面对朋友的得失时表现得更为冷漠并更具竞争性。     

Cogmic space for narrative-based world representation

Representing a world or a physical/social environment in an agent’s cognitive system is essential for creating human-like artificial intelligence. This study takes a story-centered approach to this issue. In this context, a story refers to an internal representation involving a narrative structure, which is assumed to be a common form of organizing past, present, future, and fictional events and situations. In the artificial intelligence field, a story or narrative is traditionally treated as a symbolic representation. However, a symbolic story representation is limited in its representational power to construct a rich world. For example, a symbolic story representation is unfit to handle the sensory/bodily dimension of a world. In search of a computational theory for narrative-based world representation, this study proposes the conceptual framework of a Cogmic Space for a comic strip-like representation of a world. In the proposed framework, a story is positioned as a mid-level representation, in which the conceptual and sensory/bodily dimensions of a world are unified. The events and their background situations that constitute a story are unified into a sequence of panels. Based on this structure, a representation (i.e., a story) and the represented environment are connected via an isomorphism of their temporal, spatial, and relational structures. Furthermore, the framework of a Cogmic Space is associated with the generative aspect of representations, which is conceptualized in terms of unconscious- and conscious-level processes/representations. Finally, a proof-of-concept implementation is presented to provide a concrete account of the proposed framework.     

Declarative working memory: A bio-inspired cognitive architecture proposal

Memory is considered one of the most important functions since it allows us to code, store and retrieve knowledge. These qualities make it an indispensable function for a virtual creature. In general, memory can be classified based on the durability of the stored data in working memory and long-term memory. Working memory refers to the capacity to maintain temporarily a limited amount of information in mind, which can then be used to support various abilities, including learning, reasoning, planning and decision-making. Unlike short-term memory, working memory is not only a storage site, but it is also a framework of interacting processes that involve the temporary storage and manipulation of information in the service of performing complex cognitive activities. Declarative memory is a type of long-term memory related with the storage of facts and events. This research focuses on the development of a cognitive architecture for the type of working memory that maintains and manipulates declarative information. The construction of the model was grounded in theoretical evidence taken from cognitive sciences such as neuroscience and psychology, which gave us the components and their processes. The model was evaluated through a case study that covers the encoding, storing, and retrieval stages. Our hypothesis is that a virtual creature endowed with our working memory model will provide faster access to the information needed for the ongoing task. Therefore, it improves the planning and decision-making processes.     

非符号数量表征和符号分数表征的关系

个体学习符号分数的一个关键是能对其数值形成准确表征。现有研究假设符号分数表征的认知基础是人类自婴幼儿期就具有的非符号数量表征(如表征两个集合各自的数量, 或两个数量的比例)。其证据包括表征非符号数量(尤其是非符号数量比例关系)和表征符号分数在行为和大脑神经活动层面上都表现出相关性。然而要说明非符号数量表征是符号分数表征的认知基础, 还需更多研究表明两者在数量概念上的独特相关和因果联系, 并阐明符号分数表征形成的认知机制。
