The complex and dynamic nature of systems pose a particular challenge to researchers and require the use of a research methodology designed to deal with such systems. The properties of fit, relevance, understandability, generality, control, workability, generalizability, and modifiability make Glaserian grounded theory and grounded action particularly well suited for studying systems. These methods are innovative, systemic, and sophisticated enough to reveal the underlying complexities of systems and plan actions that address their complex, dynamic nature while remaining grounded in what is occurring within the systems as they change over time.  相似文献

Understanding families as systems   总被引:2,自引:0,他引:2  
In this article, we discuss recent research that has arisen from theoretical and conceptual models that use a systems metaphor for understanding families. We suggest that research stimulated by such models leads social scientists in new and important directions in understanding the social and emotional development of children in their families. These models view development as resulting from the dynamic transactions across multiple levels of family systems, which regulate a child's behavior. Thus, these models are important in considering multiple influences on development and adaptation.  相似文献

The author discusses the contributions of grounded theory and grounded action to the development of a new, and evolutionary, theoretical framework for understanding diversity as a complex phenomenon. She discusses the work of Thomas and Gregory as pioneers in expanding the conceptualization of diversity, arguing that this new understanding increases the potential for creative action in systems.  相似文献

My response to Engelmann (2008) will be based on several questions that will allow both its author and the general reader to determine whether the assumptions I make as an interpreter of this complex paper are congruent or incongruent with their own interpretations of the text. The interpretations by the writer, by any commentator, and the diverse interpretations of a general audience together with my own interpretations will, I hope, facilitate some fruitful ‘comparative evaluations.’ I articulate my inferences of the most dense part of the paper, namely the ‘concrete immediate Consciousness and the developing absent outside.’ My hope is to address Engelmann’s question: “Am I in a better disposition to judge modern theories of consciousness?” The last section of my response spells out more personal comments to my all too brief and single encounter with Arno Engelmann. It is there that Arno Engelmann’s fascinating statement “I am a citizen of the world” is addressed through its counterparts in my life.  相似文献

The biological foundations of cognitive science   总被引:1,自引:0,他引:1  
Cognitive Science originated in reactions against behaviorism that were motivated in significant part by the example of the computer. The computer raised the exciting possibility that mind could be understood almost entirely independently of brain: if the operations of the mind are akin to the execution of a program, then almost all the relevant aspects of mind would be captured by that program, independently of whatever was running it, be it transistors or neurons. This presumed independence of cognitive science from biology has waned considerably in recent decades, but in this paper, I argue that there is at least one crucial aspect of biology that has yet to be appreciated for its relevance to mental and other normative processes—the thermodynamics of living systems. In particular, I argue that the emergence of normativity in general—and normative function and representation in particular—depends on special systems that are far from thermodynamic equilibrium; these form the interface between the factual world of atoms and molecules and the normative world of mind. The nature of that emergence, in turn, imposes strong constraints on how the central nervous system functions, and, therefore, on how cognition is realized.  相似文献

The aim of this paper is twofold. First, we provide a methodological pathway from theories of situated, embodied cognition to simulations with an eye to empirical evidence, and suggest a possible cross-fertilization between cognitive robotics and psychology. Psychological theories, in particular those formulated at an abstract level, include models which are often severely underspecified at the level of mechanisms. This is true in the synchronic, constructive perspective (how can the effects observed in experiments be concretely generated by the model's mechanisms?) and in the diachronic, developmental perspective (how can such mechanisms be learned and developed?). The synthetic method of artificial cognitive systems research, and in particular of cognitive robotics, can complement research in psychology (and neurosciences) by exploring the constructive and developmental aspects of theories. Our second aim is to provide an example of such a methodology by describing simulations aiming at developing a perceptual symbol system (PSS) (Barsalou, 1999). We then describe the two main theoretical constructs of the PSS, perceptual symbols and simulators, illustrate their development in an artificial system, and test the system in prediction, categorization, and abstraction tasks.  相似文献

The purpose of this paper was to discover the relationships among 22 relevant psychological features in semi-professional football players in order to study team’s performance and collective efficacy via a Bayesian network (BN). The paper includes optimization of team’s performance and collective efficacy using intercausal reasoning pattern which constitutes a very common pattern in human reasoning. The BN is used to make inferences regarding our problem, and therefore we obtain some conclusions; among them: maximizing the team’s performance causes a decrease in collective efficacy and when team’s performance achieves the minimum value it causes an increase in moderate/high values of collective efficacy. Similarly, we may reason optimizing team collective efficacy instead. It also allows us to determine the features that have the strongest influence on performance and which on collective efficacy. From the BN two different coaching styles were differentiated taking into account the local Markov property: training leadership and autocratic leadership.  相似文献

Individuals often hold beliefs in religion and in science, but how they mutually function is not well-understood. We examined these conjoint influences by examining their relative contributions to individuals' global meaning systems. We also examined whether subgroups of participants could be identified in terms of relative influence of religious or science beliefs on their meaning systems. A nationally representative sample of 300 American adults completed online surveys. Results suggested that science beliefs and religion beliefs comprise separate but only modestly negatively correlated dimensions. Both contributed similarly to the explanation of world assumptions, but only religious beliefs generally predicted goals, values and sense of meaning in life. Latent profile analysis produced a three-profile solution: one profile of moderate science and religious beliefs represented half the sample while the remainder split evenly between predominantly religious and predominantly science beliefs. In general, across most aspects of global meaning, the religious beliefs group was higher than the science beliefs and moderate beliefs in both groups. Results of this first systematic investigation of the separate effects of beliefs in religion and in science on meaning systems suggest that the balance of these beliefs is a potentially important individual difference warranting further investigation and elaboration.  相似文献

Introduction: Constructivism and social constructionism in the career field   总被引:1,自引:0,他引:1  
The impact of constructivism and social constructionism upon vocational psychology has often been through the use of the more generic “constructivism.” In this article constructivism is distinguished by its focus on how the individual cognitively engages in the construction of knowledge from social construction which claims that knowledge and meaning are historically and culturally constructed through social processes and action. The considerable ambiguity in the use of these terms is also discussed. Their contributions, challenges, and opportunities to the career field’s dominant discourses are examined: the dispositions discourse, the contextualizing discourse, the subjectivity and narrative discourse, and the process discourse. Broader challenges and opportunities for the field are also noted. The historical construction of knowledge, concern with language, action, and process problematize traditional understandings of career. They raise opportunities to question fundamental assumptions, focus on context, culture, the person-environment interaction, and practice.  相似文献

In this article the author maintains that complexity theory relies on reductionist assumptions, showing itself not to be completely convincing in dealing with the issue of novelty. First, an outline of Mark C. Taylor's The Moment of Complexity is presented as an exemplary case, particularly for his attempt to import complexity theory into the social sciences. Then, the connection between complexity theory and evolutionism is considered, arguing that this connection prevents complexity theory from giving a convincing account of the emergence of novelty. A provisional conclusion is offered by arguing that novelty should be conceived as arising from a “widening” of reduction at the individual level.  相似文献

Complex systems are pervasive in the world around us. Making sense of a complex system should require that a person construct a network of concepts and principles about some domain that represents key (often dynamic) phenomena and their interrelationships. This raises the question of how expert understanding of complex systems differs from novice understanding. In this study we examined individuals’ representations of an aquatic system from the perspective of structural (elements of a system), behavioral (mechanisms), and functional aspects of a system. Structure-Behavior-Function (SBF) theory was used as a framework for analysis. The study included participants from middle school children to preservice teachers to aquarium experts. Individual interviews were conducted to elicit participants’ mental models of aquaria. Their verbal responses and pictorial representations were analyzed using an SBF-based coding scheme. The results indicated that representations ranged from focusing on structures with minimal understanding of behaviors and functions to representations that included behaviors and functions. Novices’ representations focused on perceptually available, static components of the system, whereas experts integrated structural, functional, and behavioral elements. This study suggests that the SBF framework can be one useful formalism for understanding complex systems.  相似文献

The meaning maintenance model (MMM) maintains that violations of expectations can elicit compensatory behavior. When anomalies are encountered, people may compensate either by affirming an intact schema or by abstracting new, meaningful connections. Past research has shown that implicitly perceived events can be threatening, and can cause changes to behavior that were not consciously intended. However, no research has yet explored whether fluid compensation responses can occur implicitly, in response to an implicit threat. This paper introduces a novel meaning threat and provides evidence that both threat and response can happen entirely outside conscious awareness. Two studies present participants with subliminally incoherent word pairs (e.g., turn-frog). Study 1 finds that these subliminal presentations enhance the ability to implicitly learn new patterns. Study 2 finds that these same presentations lead to the affirmation of an unrelated moral schema, and to the same extent as a subliminal mortality salience manipulation.  相似文献

In this essay, I explore how cognitive science could illuminate the concept of beauty. Two results from the extensive literature on aesthetics guide my discussion. As the term “beauty” is overextended in general usage, I choose as my starting point the notion of “perfect form.” Aesthetic theorists are in reasonable agreement about the criteria for perfect form. What do these criteria imply for mental representations that are experienced as beautiful? Complexity theory can be used to specify constraints on mental representations abstractly formulated as vectors in a high‐dimensional space. A central feature of the proposed model is that perfect form depends both on features of the objects or events perceived and on the nature of the encoding strategies or model of the observer. A simple example illustrates the proposed calculations. A number of interesting implications that arise as a consequence of reformulating beauty in this way are noted.  相似文献

It is often claimed that artificial society simulations contribute to the explanation of social phenomena. At the hand of a particular example, this paper argues that artificial societies often cannot provide full explanations, because their models are not or cannot be validated. Despite that, many feel that such simulations somehow contribute to our understanding. This paper tries to clarify this intuition by investigating whether artificial societies provide potential explanations. It is shown that these potential explanations, if they contribute to our understanding, considerably differ from potential causal explanations. Instead of possible causal histories, simulations offer possible functional analyses of the explanandum. The paper discusses how these two kinds explanatory strategies differ, and how potential functional explanations can be appraised.  相似文献

We overview the main historical and technological elements characterising the rise, the fall and the recent renaissance of the cognitive approaches to Artificial Intelligence and provide some insights and suggestions about the future directions and challenges that, in our opinion, this discipline needs to face in the next years.  相似文献

Since the early 1980s, the interdisciplinary field of psychoneuroimmunology has explored the complex bi‐directional interactions between brain, behavior, and the immune system. Taken together, this research has expanded the limits of the questions we can ask about the organism by challenging the biomedical paradigm of the immune system as predominantly “autonomous”. Psychoneuroimmunology has played a key role in establishing a biological basis for the ancient idea that the mind can play a role in health and disease. This article describes the development of psychoneuroimmunology and reviews a number of key findings concerning psychological phenomena of potential relevance to understanding brain‐behavior‐immune interactions, including learning, emotions, stress, and the role of sensory processes.  相似文献

Two studies explored the effects of forget instructions on autobiographical memory at immediate test and following delays of either 12–13 months, or 3–4 months. Using the Autobiographical Think/No-Think procedure (cf., Noreen & MacLeod, 2013), 24 never-depressed participants (Study 1) first generated 12 positive and 12 negative autobiographical memories and associated cues. Participants were then asked to recall the memory associated with some of the cues (i.e., ‘think’ condition), or to avoid saying or thinking about the memory associated with other cues (i.e., ‘no-think’ condition). Participants were then asked to recall the memories associated with all the cues at immediate test and following a delay of 12–13 months. Participants were found to be successful at forgetting both positive and negative autobiographical memories following ‘no-think’ instructions at immediate test but this forgetting effect did not persist following a 12–13 month delay. This pattern of remembering and forgetting was replicated in a second study (using 27 never-depressed participants) following a 3–4 month delay. Participants who had been less successful at forgetting ‘no-think’ memories at immediate test, were more likely to show rebound effects for those memories following a delay compared to memories which received neither ‘think’ nor ‘no-think’ instructions. Individual differences in inhibitory control and the efficacy of potential therapeutic interventions of ‘no-think’ instructions are considered.  相似文献

Terror management theory (TMT) proposes that thoughts of death trigger a concern about self-annihilation that motivates the defense of cultural worldviews. In contrast, uncertainty theorists propose that thoughts of death trigger feelings of uncertainty that motivate worldview defense. University students (N = 414) completed measures of the chronic fear of self-annihilation and existential uncertainty as well as the need for closure. They then evaluated either a meaning threat stimulus or a control stimulus. Consistent with TMT, participants with a high fear of self-annihilation and a high need for closure showed the greatest dislike of the meaning threat stimulus, even after controlling for their existential uncertainty. Contrary to the uncertainty perspective, fear of existential uncertainty showed no significant effects.  相似文献

Human connectome studies suggest that the brain has a modular small world network structure with rich-club effect. Such structure emerges spontaneously in simple model neural networks, (e.g. coupled maps), through adaptive rewiring according to the dynamic functional connectivity. The utility of adaptive rewiring has so far exclusively been demonstrated for unweighted networks; it is anything but guaranteed to work as well for weighted networks. We investigate adaptive rewiring in weighted networks, comparing various right-skewed, symmetrical, and left-skewed fixed weight distributions. We examine how network clustering, path length, modularity, and rich club coefficients develop for weakly, intermediate and strongly coupled networks. At low coupling strength, the weight distribution, as well as episodes of functional synchrony, have a significant effect on network evolution. With increased coupling strengths, all weighted networks robustly develop architectures similar to the unweighted ones. Adaptive rewiring appears relatively ineffective in networks with (biologically implausibly) extreme right-skewed weight distributions but performed most economically in biologically plausible log-normal distributions.  相似文献
