To understand how individuals adapt to and anticipate each other in joint tasks, we employ a bidirectional delay–coupled dynamical system that allows for mutual adaptation and anticipation. In delay–coupled systems, anticipation is achieved when one system compares its own time‐delayed behavior, which implicitly includes past information about the other system’s behavior, with the other system’s instantaneous behavior. Applied to joint music performance, the model allows each system to adapt its behavior to the dynamics of the other. Model predictions of asynchrony between two simultaneously produced musical voices were compared with duet pianists’ behavior; each partner performed one voice while auditory feedback perturbations occurred at unpredictable times during live performance. As the model predicted, when auditory feedback from one musical voice was removed, the asynchrony changed: The pianist’s voice that was removed anticipated (preceded) the actions of their partner. When the auditory feedback returned and both musicians could hear each other, they rapidly returned to baseline levels of asynchrony. To understand how the pianists anticipated each other, their performances were fitted by the model to examine change in model parameters (coupling strength, time‐delay). When auditory feedback for one or both voices was removed, the fits showed the expected decrease in coupling strength and time‐delay between the systems. When feedback about the voice(s) returned, the coupling strength and time‐delay returned to baseline. These findings support the idea that when people perform actions together, they do so as a coupled bidirectional anticipatory system. 相似文献

ABSTRACTIn keeping with the dominant view that skills are largely automatic, the standard view of memory systems distinguishes between a representational declarative system associated with cognitive processes and a performance-based procedural system. The procedural system is thought to be largely responsible for the performance of well-learned skilled actions. Here we argue that most skills do not fully automate, which entails that the declarative system should make a substantial contribution to skilled performance. To support this view, we review evidence showing that the declarative system does indeed play a number of roles in skilled action. 相似文献

ABSTRACTMarital sexual violence is a serious problem in India. However, marital rape and most other forms of marital sexual violence are not criminalized in the country. This qualitative study with healthcare providers (physicians and nurses), lawyers, members of a non-profit organization that offers domestic violence support services out of a hospital, a journalist and two lawyers suggest that the majority of care providers recognize that marital sexual violence is a serious concern, and agree that health systems can play a vital role in addressing both the immediate biomedical concerns of survivors, and also overall well-being. The study reveals several systemic and internal factors that hinder responsiveness of Indian health institutions. These include, the absence of a protocol or uniform internal guidelines in most hospitals, a lack of screening programs to capture the presence of violence occurring when patients visit hospitals for other reasons, a large patient load, a lack of gender sensitivity in providers’ education, an absence of domestic violence shelters, and poor interlinkages between support services such as counseling and legal services. Notwithstanding these challenges, some exemplar physicians and nurses assist survivors of sexual violence, sometimes risking their own safety. The Indian health system can be made more responsive, provided these factors are addressed, and crucially budgets are allocated for interventions. 相似文献

ABSTRACTThe prevalence of trauma and its negative impact on humankind has created a burgeoning awareness of the need for systems that are trauma-informed across the lifespan. A collaborative project with the National Partnership to End Interpersonal Violence (NPEIV) sought out research as a call-to-action to mitigate the impact of trauma. The following is an introduction to a special double-issue focused on theoretical and applied approaches to using trauma-informed care in multi-disciplinary, mental and physical health, criminal justice, school-based, and community settings. Consideration is given to essential issues such as resilience, self-care, and cultural awareness. 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

The development in the interface of smart devices has lead to voice interactive systems. An additional step in this direction is to enable the devices to recognize the speaker. But this is a challenging task because the interaction involves short duration speech utterances. The traditional Gaussian mixture models (GMM) based systems have achieved satisfactory results for speaker recognition only when the speech lengths are sufficiently long. The current state-of-the-art method utilizes i-vector based approach using a GMM based universal background model (GMM-UBM). It prepares an i-vector speaker model from a speaker’s enrollment data and uses it to recognize any new test speech. In this work, we propose a multi-model i-vector system for short speech lengths. We use an open database THUYG-20 for the analysis and development of short speech speaker verification and identification system. By using an optimum set of mel-frequency cepstrum coefficients (MFCC) based features we are able to achieve an equal error rate (EER) of 3.21% as compared to the previous benchmark score of EER 4.01% on the THUYG-20 database. Experiments are conducted for speech lengths as short as 0.25 s and the results are presented. The proposed method shows improvement as compared to the current i-vector based approach for shorter speech lengths. We are able to achieve improvement of around 28% even for 0.25 s speech samples. We also prepared and tested the proposed approach on our own database with 2500 speech recordings in English language consisting of actual short speech commands used in any voice interactive system. 相似文献

This paper describes the new security solutions based on cognitive approaches and new computing paradigm called cognitive cryptography. This new security area establish a new generation of computational methods and security systems, focused on creation intelligent cryptographic algorithms and security protocols using cognitive information processing approaches. Such systems are designed for semantic evaluation of encrypted data, and allow to select the most appropriate techniques of its encryption. This paper presents a possible application of such techniques for different security tasks like authentication, secret sharing, secure data management etc. Additionally, some cryptographic solutions inspired by biological models will be presented. 相似文献

Character virtues are morally based actions that enable and individual and his or her social world to thrive across time and place. The morally valanced relation between individual and context involved in character virtue development may be studied productively by research and program evaluation focused on four facets of virtues: (a) Character virtue development involves mutually beneficial relations between the individual and the context (individual ⇔ context relations); (b) Coherence, reflecting the Aristotelian concept of phronesis, enables understanding of the specific ways in which an individual may contribute positively to the context that, in turn, supports him or her; (c) Specific character virtues develop in specific places at specific times through specific individual ⇔ context relations; and 4. Idiographic analysis is a useful first step in the study of character virtue development. Implications of these ideas for research and the evaluation of character education programs are discussed. 相似文献

The aim of this paper is to examine feeling‐toned complexes from a developmental psychological perspective. From this perspective feeling‐toned complexes emerge when basic needs are not met. A very similar theory is put forward by Jeffery Young in his Schema Therapy (Young, Klosko, & Weishaar 2005). His basic needs concept, developed on the basis of empirical research, covers four basic needs which are: attachment, autonomy, and self‐worth, as well as play and spontaneity. My proposition is to deal with this conceptual view from a Jungian perspective insofar as we can integrate the four basic needs, however adding a fifth: the basic need for meaning in the theory of feeling‐toned complexes. Emotional schemas and feeling‐toned complexes are then comparable patterns. The strengths and weaknesses of Analytic Psychology compared to Jeffrey Young's schema therapy are further discussed. The foundation of the feeling‐toned complexes on unmet basic needs lends itself to including a further reference, namely Jaak Panksepp’s neuroscientific findings. Panksepp formulates seven basic affective systems which I discuss first, then I focus on what could be gained from the basic needs concept and finally I turn to the feeling‐complex in an attempt to integrate neuroscientific findings into complex theory. 相似文献

The paper reviews the course of the controversy surrounding Jung's theory of archetypes beginning in the mid 1990s and continuing to the present. Much of this controversy was concerned with the debate between the essentialism of the evolutionary position of Anthony Stevens as found in his 1983 book Archetypes: A Natural History of the Self, and the emergence model of the archetypes proposed in various publications by Hogenson, Knox and Merchant, among others. The paper then moves on to a consideration of more recent developments in theory, particularly as derived from an examination of the philosopher Gilles Deleuze, who introduces Bergson's somnambulistic unconscious into the discussion of Jung's theories. It is suggested that this largely unexamined influence on Jung may provide answers to some of the unanswered questions surrounding his theorizing. The paper concludes by suggesting that the notion of the somnambulistic unconscious may resemble Atmanspacher's argument for a dual‐aspect monism interpretation of Jung. 相似文献
