Emergence from brain architectures: a new cognitive science?

The way in which artificial intelligence has developed over the last 50 years has had a major role in shaping cognitive science as it is today. This has generated computational models of behaviour. The connectionist revival of the 1980s added a tinge of neurodynamics to this. Here I suggest that some post-connectionist work in artificial intelligence is turning towards an understanding and formalisation of the mechanisms of brain architectures which contribute to an emergence of cognition providing a closer link between brain mechanisms and experienced brain states. This even addresses the neurological basis of consciousness.     

A computational cognitive model of syntactic priming

The psycholinguistic literature has identified two syntactic adaptation effects in language production: rapidly decaying short-term priming and long-lasting adaptation. To explain both effects, we present an ACT-R model of syntactic priming based on a wide-coverage, lexicalized syntactic theory that explains priming as facilitation of lexical access. In this model, two well-established ACT-R mechanisms, base-level learning and spreading activation, account for long-term adaptation and short-term priming, respectively. Our model simulates incremental language production and in a series of modeling studies, we show that it accounts for (a) the inverse frequency interaction; (b) the absence of a decay in long-term priming; and (c) the cumulativity of long-term adaptation. The model also explains the lexical boost effect and the fact that it only applies to short-term priming. We also present corpus data that verify a prediction of the model, that is, that the lexical boost affects all lexical material, rather than just heads.     

数量对时间知觉的影响-来自抽象数量和实际数量的证据

本研究采用抽象数量和实际数量叠加的方式呈现刺激,进一步探讨数量对时间知觉的影响。两个实验都运用时间的系列比较任务,以抽象数量和实际数量这两种数量的一致和不一致为条件,将阿拉伯数字和其字体大小叠加及阿拉伯数字和其呈现个数叠加的方式系列呈现在屏幕中央,要求被试比较判断刺激呈现的时间长短。结果显示被试均依靠实际数量的大小判断时间长短,而似乎忽略了抽象数量的存在。这一结果表明实际数量对时间知觉的影响要比抽象数量大,支持并扩展了数量理论。     

Staying or returning: Pre‐migration influences on the migration process of German migrants to New Zealand

Changes in migrants' backgrounds and societies sending and receiving migrants might increase adaptation issues and reduce retention. To enhance migrants' well‐being/health and their likelihood of staying it is necessary to gain an understanding of psychological and social factors that contribute to resilience and adaptation. This paper presents findings from a qualitative study that investigated the experiences, interpretations and actions of German migrant couples to New Zealand throughout the whole migration process to identify these factors. In depth, episodic interviews were conducted with four couples who decided to stay in New Zealand and four couples who decided to return to Germany. Interview data were complemented with participant observation. This paper provides insights into how the pre‐migration experiences, interpretations and actions of German migrants to New Zealand influenced their establishment, their interpretations and actions and consequently adaptation, well‐being/health and the decision whether to stay in New Zealand or to return to Germany. The findings illuminate the influence of psychological and social factors on migration experiences, interpretations and actions throughout the migration process. The paper offers some solutions for addressing the identified barriers to successful migration and integration into host societies. Copyright © 2008 John Wiley & Sons, Ltd.     

Modern racism and neo‐liberal globalization: the discourses of plausible deniability and their multiple functions

Recently, considerable energy has been focused on extending the mandate of anti‐racism. Modern (or symbolic) racism and discursive psychology have argued that racism has taken on more covert forms. A longitudinal examination of newspaper coverage of two important race‐related newsprint stories in New Zealand (involving Winston Peters, Tuku Morgan and New Zealand First) identified discourses of ‘plausible deniability’ involved in warranting or defending statements about minorities against accusations of racism. We discuss implications of symbolic politics for minorities who are perceived to have violated societal norms, and show how nationalism is used as a framework for denying racist intent. Analyses of historical context show how ‘race’ forms only one lens from which to view issues of intergroup relations. While the press was sensitive to issues of racism, they demonstrated little awareness of concurrent issues of neo‐liberal economics, or market fundamentalism. Anti‐racism may be motivated not only by the ideals of egalitarianism, but also by underlying dynamics of economic power in a global economy. Copyright © 2006 John Wiley & Sons, Ltd.     

Biotechnology in the Japanese media: Comparative analysis of newspaper articles on genetic engineering in Japan and Europe

The present study examined how the representations of biotechnology using genetic engineering have been developed in Japan relying on media analysis. Specifically, using the online database of the Asahi Shimbun , one of the major opinion-forming newspapers in Japan, the annual numbers of articles concerning biotechnology were tallied from 1985 to 2000, and an analysis was conducted of the content of 850 articles from 10 particular years. Specifically, a framework in which a biotechnological issue was presented was focused on; the changes of dominant frames and the relationships between frames and specific biotechnological applications (e.g. medicine, agrifood and cloning) were investigated. The results showed that: (i) the number of articles increased sharply in particular since 1996–1997; (ii) although general attitudes toward biotechnology were persistently positive, a frame of biotechnological article became more diverse (i.e. the prospect frames were considerably dominant in the earlier phases, but the concern frames also became prominent in the later phases); and (iii) several articles were found which reported cloned animals in a frame of emotional attachment, a frame unique to Japan. These results were compared with those of European countries and discussed from a perspective of the theory of collective symbolic coping.     

Parent–Infant Synchrony: Biological Foundations and Developmental Outcomes

ABSTRACT— Synchrony—a construct used across multiple fields to denote the temporal relationship between events—has been applied to the study of mother–infant interaction and is suggested here as a framework for the study of interpersonal relationships. Defined as the temporal coordination of micro-level social behavior, parent–infant synchrony is charted in its development across infancy from the initial consolidation of biological rhythms during pregnancy to the emergence of symbolic exchange between parent and child. Synchrony is shown to depend on physiological mechanisms supporting bond formation in mammals—particularly physiological oscillators and neuroendocrine systems such as those involving the hormone oxytocin. Developmental outcomes of the synchrony experience are observed in the domains of self-regulation, symbol use, and the capacity for empathy across childhood and adolescence. Specific disruptions to the parameters of synchrony that may be observed in various pathological conditions, such as prematurity or maternal affective disorder, are detailed. A time-based, micro-analytic behavioral approach to the study of human relationship may offer new insights on intersubjectivity across the lifespan.     

Creativity and dialectical phenomena From dialectical edge to dialectical space1

The seeds of creativity have the potential to germinate and flourish within the rich, ambiguous and unsettling tapestry of the core dialectical tensions related to the central organizing dialectic, life and death, generated in the patient‐analyst relating. The author introduces the concept of the ‘dialectical edge’ and describes it as the pivotal point in the dialectical struggle within these core dialectical dilemmas. This is a fluid, emotionally evocative threshold, where there is maximum potential for change, as well as for homeostatic stagnation. Drawing on Winnicott, the author illustrates how the presence of an edge within these dialectical dilemmas has the potential to open up into a creative, reflective space. He suggests that this, however, will depend on the therapist's capacity to contain/hold at this edge the arousing and intense affects‐such as anxiety, dread, excitement and passion‐that are inevitably generated at these pivotal relational moments. This will determine whether the patient will move forwards into the light of a creative, reflective, dialectical space, or backwards into collapsed, non‐reflective darkness, where fluid oscillation is transformed into rigid ossification. The author uses a clinical example to illustrate these dialectical phenomena, with a special focus on two clinically relevant dialectics, i.e. ‘ritual versus spontaneity’ and ‘closeness versus separateness’.     

The role of cognitive architectures in general artificial intelligence

The term “Cognitive Architectures” indicates both abstract models of cognition, in natural and artificial agents, and the software instantiations of such models which are then employed in the field of Artificial Intelligence (AI). The main role of Cognitive Architectures in AI is that one of enabling the realization of artificial systems able to exhibit intelligent behavior in a general setting through a detailed analogy with the constitutive and developmental functioning and mechanisms underlying human cognition. We provide a brief overview of the status quo and the potential role that Cognitive Architectures may serve in the fields of Computational Cognitive Science and Artificial Intelligence (AI) research.     

A Review of Experimental Research on Embodied Creativity: Revisiting the Mind–Body Connection

A growing body of experimental work highlights the potential value of unstructured, interactive, or spontaneous motions, including gestures, dance, shifting body postures, physical object-manipulation, drawing, etc. to favorably impact creative performance. However, despite these favorable findings, to our knowledge, no systematic review has been conducted to explore the totality of evidence for embodied activities in this arena. Thus, the objective of this paper was to systematically evaluate the potential effects of embodied experimental manipulations on traditionally assessed creativity outcomes. A systematic review was conducted utilizing PubMed, PsychInfo, Sports Discus, and Google Scholar databases. The 20 studies evaluated employed a variety of methodological approaches regarding study design, embodied manipulation, and selection of specific creativity outcomes. Despite these variations, embodied movement robustly enhanced creativity across nearly all studies (90%), with no studies showing a detrimental effect. Based on the evaluation of the studies reviewed, several common themes emerged. These included the relevance of symbolic metaphors and distributed embodied cognitions, selection of embodied modality, specific measurement considerations, as well as the importance for implementing true, inactive control conditions in embodied creativity research. This review expands on these findings and places them in the context of improving future embodied creativity research.
