Categorical priming of famous person recognition: a hitherto overlooked methodological factor can resolve a long-standing debate

The Burton, Bruce and Johnston [Burton, A. M., Bruce, V., & Johnston, R. A. (1990). Understanding face recognition with an interactive activation model. British Journal of Psychology, 81, 361-380] model of person recognition proposes that representations of known persons are connected by shared semantic attributes. This predicts that priming should be observed between persons from the same category, e.g. famous persons with the same occupation. Empirical investigations to date have produced mixed results, and comparison of methods suggests that priming based on shared occupation may have been suppressed by the presence of prime-target pairs representing a stronger relationship of close association. In the present experiment, 72 participants performed a familiarity decision to famous names preceded by close associates or members of the same occupational category. As predicted, categorical priming was observed in the group of participants for whom the same occupation prime-target pairs were presented before the close-associate pairs, but not in the group for whom the two types of relationship were intermixed. Associate priming was significant in both groups. These results are attributed to differing levels of processing of the primes, invoked by participants' observation of the most salient prime-target relationship.     

Faceted Thesauri

The basic elements of faceted thesauri are described, together with a review of their origins and some prominent examples. Their use in browsing and searching applications is discussed. Faceted thesauri are distinguished from faceted classification schemes, while acknowledging the close similarities. The paper concludes by comparing faceted thesauri and related knowledge organization systems to ontologies and discussing appropriate areas of use.     

Salvaging and secularizing the semantic contents of religion: the limitations of Habermas’s postmetaphysical proposal

The article considers Jürgen Habermas’s views on the relationship between postmetaphysical philosophy and religion. It outlines Habermas’s shift from his earlier, apparently dismissive attitude towards religion to his presently more receptive stance. This more receptive stance is evident in his recent emphasis on critical engagement with the semantic contents of religion and may be characterized by two interrelated theses: (a) the view that religious contributions should be included in political deliberations in the informally organized public spheres of contemporary democracies, though translated into a secular language for the purposes of legislation and formal decision making and (b) the view that postmetaphysical philosophy should seek to salvage the semantic contents of religious traditions in order to supply the evocative images, exemplary figures, and inspirational narratives it needs for its social and political projects. With regard to (a), it argues that the translation requirement impairs the political autonomy of religious believers and other metaphysically inclined citizens, suggesting that this difficulty could be alleviated by making a distinction between epistemologically authoritarian and non-authoritarian religious beliefs. With regard to (b), it argues that the salvaging operation is not as straightforward as Habermas seems to suppose and that social and political philosophy may not be able to tap the semantic power of religious traditions without relying on metaphysical assumptions; it concludes that, here, too, a distinction between authoritarian and non-authoritarian approaches to knowledge and validity may be useful.     

Semantic boost on episodic associations: an empirically-based computational model

Words become associated following repeated co-occurrence episodes. This process might be further determined by the semantic characteristics of the words. The present study focused on how semantic and episodic factors interact in incidental formation of word associations. First, we found that human participants associate semantically related words more easily than unrelated words; this advantage increased linearly with repeated co-occurrence. Second, we developed a computational model, SEMANT, suggesting a possible mechanism for this semantic-episodic interaction. In SEMANT, episodic associations are implemented through lateral connections between nodes in a pre-existent self-organized map of word semantics. These connections are strengthened at each instance of concomitant activation, proportionally with the amount of the overlapping activity waves of activated nodes. In computer simulations SEMANT replicated the dynamics of associative learning in humans and led to testable predictions concerning normal associative learning as well as impaired learning in a diffuse semantic system like that characteristic of schizophrenia.     

Semantic re-interpretation and garden path recovery

Participant's eye-movements were recorded while they read locally ambiguous sentences. Evidence for processing difficulty was found when the interpretation of the initially preferred misanalysis clashed with that of the globally correct analysis, demonstrating the persistence of the earlier interpretation. Processing difficulty associated with the syntactic reanalysis was largely localised to the disambiguating region, with difficulty due to semantic persistence occurring later. The results show that semantic persistence is not limited to extreme cases of parse failure, and can occur even when reanalysis is relatively straightforward.     

From grammatical number to exact numbers: early meanings of 'one', 'two', and 'three' in English, Russian, and Japanese

This study examined whether singular/plural marking in a language helps children learn the meanings of the words 'one,' 'two,' and 'three.' First, CHILDES data in English, Russian (which marks singular/plural), and Japanese (which does not) were compared for frequency, variability, and contexts of number-word use. Then young children in the USA, Russia, and Japan were tested on Counting and Give-N tasks. More English and Russian learners knew the meaning of each number word than Japanese learners, regardless of whether singular/plural cues appeared in the task itself (e.g., "Give two apples" vs. "Give two"). These results suggest that the learning of "one," "two" and "three" is supported by the conceptual framework of grammatical number, rather than that of integers.     

Creating a strategy for progress: a contextual behavioral science approach

Behavior analysis is a field dedicated to the development and application of behavioral principles to the understanding and modification of the psychological actions of organisms. As such, behavior analysis was committed from the beginning to a comprehensive account of behavior, stretching from animal learning to complex human behavior. Despite that lofty goal, basic behavior analysis is having a generally harder time finding academic support, and applied behavior analysis has narrowed its focus. In the present paper we argue that both of these trends relate to the challenge of human language and cognition, and that developments within clinical behavior analysis and the analysis of derived relational responding are providing a way forward. To take full advantage of these developments, however, we argue that behavior analysts need to articulate their unique approach to theory, to develop more flexible language systems for applied workers, and to expand their methodological flexibility. This approach, which we term contextual behavioral science, is meant as an evolutionary step that will allow behavior analysis to better capture the center of modern psychological concerns in both the basic and applied areas. Clinical behavior analysis is showing a way forward for behavior analysis to regain its vision as a comprehensive approach to behavior.     

胃癌根治术中常规放置空肠营养管的博弈思考

规范化的胃癌根治术是我国胃癌治疗的发展方向,本文回顾性分析胃癌根治术中常规放置空肠营养管和术后早期肠内营养在胃癌规范化治疗中的作用。结果表明空肠营养管置入和对照组术后并发症率无显著性差异（P=0.501）,早期联合肠内营养可有效缩短住院时间（P=0.0115）。结合博弈论的观点分析,胃癌根治术中放置空肠营养管在并发症预防和治疗中有重要作用,可能避免不必要的二次开腹手术,因此是一种对于医患双方都最为有利的策略选择。     

经肛直肠癌切除术的应用现状

在严格选择适应证的条件下,经肛直肠癌切除术是治疗早期低位直肠癌的可选术式之一。相比于直肠癌前切除术和经腹会阴切除术,经肛切除术具有创伤小,并发症少等特点。关于经肛切除术后的局部复发率以及综合治疗对经肛切除术治愈能力的影响尚存在争议。本文将对经肛切除术做一系统的回顾。     

牙源性角化囊性瘤治疗的哲学思考

牙源性角化囊性瘤原称牙源性角化囊肿,因其生长缺乏自限性,具有某些肿瘤的特征,术后有较高复发倾向,WHO将其归属为良性牙源性肿瘤,并命名为牙源性角化囊性瘤。其治疗方法主要有保守性和根治性两种,医师应严格掌握两种治疗方法的适应证和禁忌证,以更大的责任心给予牙源性角化囊肿患者最好的治疗和更多的人文关爱。
