This paper proposes an account of the self as a multilevel system consisting of social, individual, neural, and molecular mechanisms. It argues that the functioning of the self depends on causal relations between mechanisms operating at different levels. In place of reductionist and holistic approaches to cognitive science, I advocate a method of multilevel interacting mechanisms. This method is illustrated by showing how self-concepts operate at several different levels.  相似文献

During the last millennium the world economic and geopolitical conflicts were to a great extent connected: different crises in the World System's evolution stimulated geopolitical shifts and vice versa. This article argues that in the 15th century different geopolitical events and conflicts in Central Asia initiated the fall of the previous World System and the rise of the new one. This transformation resulted in the fall of overland and river trade routes, including the Great Silk Route, which passed through Central Asia. World trade shifted to sea and ocean routes, and European countries became the center of the new World System. Now, in the beginning of the 21st century a new transformation of the World System is underway. The center of economic and political development is migrating gradually to the East: this is why the geopolitical role of the Central Asian states is increasing. Central Asian states are a very important part of the New Silk Route; this route is to connect Eastern Asia with Europe and the Middle East. The United States, China, Russia, and other states are ardently competing to control the New Silk Route. Hence, different geopolitical, social, and military conflicts are probable in Central Asia. So economic and political integration in Eurasia between Russia, China, the United States and Central Asian states is very important for the geopolitical stabilization of the region. The article evaluates the main scenarios of geopolitical changes in Central Asia.  相似文献

Like all natural sciences, behavior science has much to offer toward an understanding of the world. The extent to which the promise of behavior science is realized, though, depends upon the extent to which we keep what we know before us. This paper considers fundamental concepts in behavior science, including the concepts of behavior, stimulation, setting conditions, and language. In considering these concepts, we revisit comments from B. F. Skinner and J. R. Kantor and also consider some areas of behavior analytic research and the implications they have for reconsidering long-held assumptions about the analysis of behavior. We hope that, in considering our foundations, the vitality and strength of the discipline might be enhanced, our impact on science improved, and our future secured.  相似文献

The aim of this study was to compare three different psychotechnical test batteries in Turkey (Act and React Test system – ART2020, TRAFIKENT, and Vienna Test System) which are used to evaluate safe driving-related ability traits and to evaluate the construct validity of the tests included in these three test systems that claim to measure the same cognitive structures. Therefore, 176 drivers (19–63 years old), who owned a driving license for at least one year and had driven at least 5000 km, were tested in all three systems. Both professional and amateur drivers as well as drivers whose licenses were detained due to speeding, DWI or other violations were included in order to form a heterogeneous and representative sample for the Turkish driver population. Participants completed the three psychotechnical batteries which tested their cognitive and psychomotor skills in a period of two or three days. The analysis of the findings revealed that the three batteries were more compatible for some cognitive abilities whereas they were less compatible for other abilities. For instance, there were higher similarities among the systems in skills such as reasoning, visual memory, and attention, while there were lower similarities in terms of reaction speed, visual continuity, coordination, speed distance estimation, and visual field. The results were discussed and evaluated so as to improve traffic safety in Turkey, and further suggestions for enhancement in traffic situations followed.  相似文献

This study explored how skills in one region of a perceptual-motor landscape of performance, created in part by previous experience in rock climbing, can shape those that emerge in another region (ice climbing). Ten novices in rock climbing and five intermediate rock climbers were observed climbing an icefall. Locations of right and left ice tools and crampons were videotaped from a frontal camera. Inter-individual variability of upper and lower limb couplings and types of action regarding icefall properties were assessed by cluster hierarchical analysis, distinguishing three clusters. Pelvis vertical displacement, duration and number of pelvis pauses were also analyzed. Experienced rock climbers were grouped in the same cluster and showed the highest range and variability of limb angular locations and coordination patterns, the highest vertical displacement and the shortest pelvis plateaux durations. Non-fluent climbers (clusters 2 and 3) showed low range and variability of limb angular locations and coordination patterns. In particular, climbers of cluster 3 exhibited the lowest vertical displacement, the longest plateaux durations and the greatest ratio between tool swinging and definitive anchorage. Our results exemplified the positive influence of skills in rock climbing on ice climbing performance, facilitated by the detection of affordances from environmental properties.  相似文献

In psychological measurement, two interpretations of measurement systems have been developed: the reflective interpretation, in which the measured attribute is conceptualized as the common cause of the observables, and the formative interpretation, in which the measured attribute is seen as the common effect of the observables. We advocate a third interpretation, in which attributes are conceptualized as systems of causally coupled (observable) variables. In such a view, a construct like ’depression’ is not seen as a latent variable that underlies symptoms like ’lack of sleep’ or ’fatigue’, and neither as a composite constructed out of these symptoms, but as a system of causal relations between the symptoms themselves (e.g., lack of sleep → fatigue, etc.). We discuss methodological strategies to investigate such systems as well as theoretical consequences that bear on the question in which sense such a construct could be interpreted as real.  相似文献

Human participants and recurrent (“connectionist”) neural networks were both trained on a categorization system abstractly similar to natural language systems involving irregular (“strong”) classes and a default class. Both the humans and the networks exhibited staged learning and a generalization pattern reminiscent of the Elsewhere Condition (Kiparsky, 1973). Previous connectionist accounts of related phenomena have often been vague about the nature of the networks’ encoding systems. We analyzed our network using dynamical systems theory, revealing topological and geometric properties that can be directly compared with the mechanisms of non‐connectionist, rule‐based accounts. The results reveal that the networks “contain” structures related to mechanisms posited by rule‐based models, partly vindicating the insights of these models. On the other hand, they support the one mechanism (OM), as opposed to the more than one mechanism (MOM), view of symbolic abstraction by showing how the appearance of MOM behavior can arise emergently from one underlying set of principles. The key new contribution of this study is to show that dynamical systems theory can allow us to explicitly characterize the relationship between the two perspectives in implemented models.  相似文献

Adolescent career development has predominantly been studied in the context of middle class Eurocentric cultures and there have been calls for greater attention to the career development of non-dominant and disadvantaged groups. Further, there have been calls to explore career development in terms of its context and process. In this regard, the need for research measures and approaches sensitive to adolescents and particular cultures has been recognised. This is particularly the case in South African career psychology. The present study used a qualitative career assessment instrument, My System of Career Influences, to explore influences on the career development of disadvantaged South African adolescents living in a children's home. Consistent with previous international and national studies, parents were shown to be an important influence. Unlike previous studies, the influence of working overseas was also identified as an important influence. The MSCI was shown to be effective in providing insight into both the context and process of career development and as a research instrument that may be used with adolescents. Recommendations for future research are made.  相似文献

Background: Levels of psychological distress appear to be increasing in the workplace, in parallel with the growth of employee assistance programme (EAP) provision offering a range of talking treatments. However, such growth takes place in the absence of a substantive body of supporting research evidence despite a quarter of a decade of research activity. Aims: To analyse a national sample of EAP data and profile relative service quality on a set of key service indicators. Method: CORE System data profiles of over 28,000 clients were voluntarily donated by six EAP service providers. An established benchmarking methodology was used to assess the relative quality of EAP service provision compared with published CORE System benchmarks for NHS primary care and UK higher education student counselling services. Results: High quality data profiled an EAP service clientele who were quantifiably distressed, accessed treatment quickly, with the majority completing treatment and demonstrating high rates of recovery and/or improvement relative to published benchmarks from the NHS and HE comparative sectors. Limitations of the study and implications for practice and further investigation are considered.  相似文献

Anticipatory reactions are hypothesized to affect physiological conditions through multiple processing systems. To determine whether anticipatory reactions include the immune system, immune variables from 73 patients treated with immunomodulating chemotherapy for breast or ovarian cancer were studied in a hospital treatment setting and compared with samples obtained in the patients' homes 2 days earlier. The number of white blood cells increased significantly between samples. Increases were also observed in the counts and proportions of granulocytes, while decreases were observed in the counts and proportions of lymphoyctes. No changes were observed in a healthy control group. The nervous system executes regulatory effects on the formation and distribution of leukocytes. Such mechanisms render psychological influences on blood samples possible, including samples that form the basis for decisions related to cancer treatment. The immune changes observed are discussed in relation to mechanisms and adaptive values of anticipation and neurally mediated impacts on the immune system.  相似文献
