1再认、思维和学习的信息过程显示文摘心理学史上的重大进展往往是通过从自然科学其它分支借用来的理论和概念的结合而产生的。自从心理学的“派别”之争逐渐平息,研究转向事实的积累,并采用多学科的研究方法以加强心理学的科学性以来,情况更是如此(荆其诚,1962,1982)。过去三十年中,在解释认知过程作为由物理符号系统实现的过程方面已经取得很大的进展。这些进展导致了现在通常称为认知科学的新学科的诞生,Herbert A.Simon 荆其诚 罗春荣 1989心理科学通讯1989,12,3:2

6计算机科学的某些方向显示文摘最近我们收到美国卡内基-梅隆大学(CMU)计算机学院的一份研究指南(Fa-culty Research Guide1989—1990),其中有不少是世界著名计算机科学家所写。我们作了摘译,介绍该学院部分学者的研究方向以供国内同行参考。Herbert A.Simon 李波 康建初 罗玉龙 1991计算机科学1991,18,1:0
7再认、思维和学习的信息过程(续)显示文摘三、思维与推理在历史上,思维,特别是“逻辑”思维和数学思维一直是与形式逻辑和数学的严密性联系在一起的。这种观点代表如此不完善的真理,不如说根本就不是真理。这一错误是把逻辑学和数学的形式推论规则,其本身的功能是检验已作出的推论是否有效,与发现可以从已有定律推论出来的新定律的过程相混淆而产生的。Herbert A.Simon 荆其诚 1989心理科学通讯1989,12,4:0
8Magnetotactic bacteria from the human gut microbiome associated with orientation and navigation regions of the brain显示文摘Magnetotactic bacteria(MTB),ubiquitous in soil and fresh and saltwater sources have been identified in the microbiome of humans and many animals.MTB endogenously produce magnetic nanocrystals enabling them to orient and navigate along geomagnetic fields.Similar magnetite deposits have been found throughout the tissues of the human brain,including brain regions associated with orientation such as the cerebellum and hippocampus,the origins of which remain unknown.Speculation over the role and source of MTB in humans,as well as any association with the brain,remain unanswered.We performed a metagenomic analysis of the gut microbiome of 34 healthy females as well as grey matter volume analysis in magnetite-rich brain regions associated with orientation and navigation with the goal of identifying specific MTB that could be associated with brain structure in orientation and navigation regions.We identified seven MTB in the human gut microbiome:Magnetococcus marinus,Magnetospira sp.QH-2,Magnetospirillum magneticum,Magnetospirillum sp.ME-1,Magnetospirillum sp.XM-1,Magnetospirillum gryphiswaldense,and Desulfovibrio magneticus.Our preliminary results show significant negative associations between multiple MTB with bilateral flocculonodular lobes of the cerebellum and hippocampus(adjusted for total intracranial volume,uncorrected P<0.05).These findings indicate that MTB in the gut are associated with grey matter volume in magnetite-rich brain regions related to orientation and navigation.These preliminary findings support MTB as a potential biogenic source for brain magnetite in humans.Further studies will be necessary to validate and elucidate the relationship between these bacteria,magnetite concentrations,and brain function.Rozalyn A.SIMON Purnika Damindi RANASINGHE Nawroz BARAZANJI Malin Bergman JUNGESTRÖM Jie XU Olga BEDNARSKA Lena SERRANDER Maria ENGSTRÖM Dennis A.BAZYLINSKI Åsa V.KEITA Susanna WALTER 2021Journal of Oceanology and Limnology2021,39,6:0
