Increased "rate of change" in cardiac sensory neurons (transducing BP, rhythm, etc.) Page 45-53 A: Good. Vagally mediated efferent HRV provides an index of the cognitive and emotional resources needed for efficient functioning in challenging environments in which delayed responding and behavioral inhibition are critical. (2011). Physiologically, the coherence state is marked by the development of a smooth, sine-wave-like pattern in the heart rate variability trace. Purpose means a sense of core goals, aims, and direction in life. *Corresponding Author: Mahvash, Salsali. Notice how each pattern looks quite different from the others. These two types are explained below. , Coherence means a sense of comprehensibility and one’s life making sense. Although physiological coherence is a natural human state that can occur spontaneously, sustained episodes generally are rare. Efficient and harmonious functioning of the cardiovascular, nervous, hormonal and immune systems. Coherence requires that group members are attuned and emotionally aligned and that the group’s energy is globally organized and regulated by the group as a whole. We also suggest that rhythmic activity in living systems reflects the regulation of interconnected biological, social and environmental networks and that important biologically relevant information is encoded in the dynamic patterns of physiological activity. Physics, Optics. In humans, this includes our physical, mental, emotional and social systems. Thus, our findings essentially underscore what people have intuitively known for some time: Positive emotions not only "feel better," they actually tend to increase synchronization of the body’s systems, thereby enhancing energy and enabling us to function with greater efficiency and effectiveness. The concept of sense of coherence (SOC) was put forward by Aaron Antonovsky in 1979 to explain why some people become ill under stress and others stay healthy. [163, 168]. Professor, Faculty of Nursing and Midwifery, Tehran University of Medical Sciences, Tehran, Iran. Coherence is a statistical measure that shows the degree that two ergodic signals are related through a linear process (non-linearities and additional noise sources will decrease coherence). Page 2/34. The left-hand side is the spectral analysis before Freeze-Framing. A detailed discussion on the nature of coherence can be found in two seminal articles. Text analysis focussing on coherence is primarily concerned with the construction and configuration of sense in the text i.e. This means that learning to generate ... and we also have increased mental clarity and improved cognitive function. Coherence A Cognitive Approach Leadership Research And Practice community so both leader and led are guided by a mutual purpose. coherence a cognitive approach leadership research and practice now is not type of challenging means. In such cases, we will simply assume the identity of the entities referred to, in what might be called a "petty conversational implica- ture," thereby solving the coherence and coreference problems simultaneously.

The quality of being orderly, consistent and intelligible (e.g. An ideal example is a system that exhibits sine-wavelike oscillations; the more stable the frequency, amplitude and shape, the higher the degree of coherence. In terms of heart and brain diagnostics and biofeedback, it means working with biology's own system of harmonically fusing emotional and mental waves or vibrations into a single, self-enforcing flow. Due to these relations, the text appears to be logically and semantically consistent for the reader-hearer. In some cases, when two or more oscillatory systems operate at the same basic frequency, they can become either phase- or frequency-locked, as occurs between the photons in a laser. Subcortical structures constantly compare information from internal and external sensory systems via a match/mismatch process that evaluates current inputs against past experience to appraise the environment for risk or comfort and safety. We have observed this association between emotions and heart-rhythm patterns in studies conducted in both laboratory and natural settings and for both spontaneous and intentionally generated emotions. Coherence describes the fit between the aim, the philosophical perspective adopted, and the researcher role in the study as well as the methods of investigation, … b : integration of diverse elements, relationships, or values "The various parts of this … Biologist Mae-Won Ho has suggested that coherence is the defining quality of living systems and accounts for their most characteristic properties, such as long-range order and coordination, rapid and efficient energy transfer and extreme sensitivity to specific signals.[165]. A constructive waveform produced by two or more waves that are phase- or frequency-locked. 1 February 2011, Vaismoradi, M.1 (MSN); Salsali, M.2* (PhD). In physics, coherence also is used to describe the coupling and degree of synchronization between different oscillating systems. Approach Leadership Research And Practice coherence a cognitive approach leadership research and practice.Most likely you have knowledge that, people have see numerous time for their favorite books bearing in mind this leadership and coherence a cognitive approach leadership research and practice, but stop happening in harmful downloads. Coherence always implies correlations, connectedness, consistency and efficient energy utilization. State-specific emotions are reflected in the patterns of the heart’s rhythms independent of changes in the amount of heart rate variability. Receive your Free copy Keywords: Coherence, Rigor, Qualitative methodology. Coherence in qualitative research. The study of both cohesion and coherence is a favourite field of research among linguists. They found that most groups have a global organization and coherent network of emotional energetic relations interconnecting virtually all members into a single multilevel hierarchy.[170]. Many contemporary scientists believe it is the underlying state of our physiological processes that determines the quality and stability of the feelings and emotions we experience. Anyone who has watched a championship sports team or experienced an exceptional concert knows that something special can happen in groups that transcends their normal performance. Interested in European research? The most common dictionary definition is the quality of being logically integrated, consistent and intelligible, as in a coherent statement. It is available in English, French and German. In addition, in the long run, it results in uncontrolled methodological diversities and inability to define criteria to judge qualitative research reports. If this were not happening, it would be a free-for-all among the body’s independent systems, rather than a coordinated federation of interdependent systems and functions. And what if the highest goal achievable, as a result, is simply the internal coherence of a speculative argument? Both concepts, traditionally connected with the reading process, have become an important tool in order to teach students how to write a text. Coherence in conversations and in texts can be partially characterized by a set of ... phrases to be coreferential. [163] This harmonious order signifies a coherent system, whose efficient or optimal function is directly related to the ease and flow in life processes. After studying three different samples – 680 students, 180 parents and 315 couples – we conclude that family relational and psychopathological variables contribute significantly to the explanation of SOC (explained variance between 10–27 and 26–50 per cent). Order within a singular oscillatory waveform. For example, frequency pulling and entrainment can easily be seen between the heart, respiratory and bloodpressure rhythms as well as between very-low-frequency brain rhythms, craniosacral rhythms and electrical potentials measured across the skin. It is a real quantity with values between 0 and 1 (where 1 means one signal can be completely established from the other through a linear filter). These are sinusoidal functions which means they not only have an amplitude ( a measure) but also a phase. A free sample copy or free subscription can be obtained from: European Commission Directorate-General for Research Information and Communication Unit It is found by the ratio of the cross power spectral density divided by the … 20 No. When a person is in a more coherent state there is a shift in the relative autonomic balance toward increased parasympathetic activity (vagal tone), increased heart-brain synchronization and entrainment between diverse physiological systems. Vol. Internal Coherence simply means that consciousness is in control. This gives your essay coherence. It seems as though the players are in sync and communicating on an unseen energetic level. See more. This is an agreed simple means to specifically acquire guide by on-line. The information contained in the interbeat intervals in the heart’s activity is communicated across multiple systems and helps synchronize the system as a whole. The coherence model takes a dynamic systems approach that focuses on increasing people’s self-regulatory capacity through self-management techniques that induce a physiological shift, which is reflected in the heart’s rhythms. The various centers within the brain also must be able to dynamically synchronize their activity in order for information to be smoothly processed and perceived. Coherence is when your brain (thoughts and decisions) work hand-in-hand with your heart (emotions) and body (actions you take). Using referents and synonyms as we’ve seen will help you achieve cohesion. Linguistics. For the brain and nervous system to function optimally, the neural activity, which encodes and distributes information, must be stable and function in a coordinated and balanced manner. Professor, Faculty of Nursing and Midwifery, Tehran University of Medical Sciences, Tehran, Iran. A brief summary of the psychophysiological coherence model is provided below. In contrast, an erratic, discordant pattern of activity denotes an incoherent system whose function reflects stress and inefficient utilization of energy in life processes. [51, 133] This is likely because of more organized outputs of the subcortical structures involved in processing emotional information, as described by Pribram,[169] Porges,[82] Oppenheimer and Hopkins[117] and Thayer,[89] in which the subcortical structures influence the oscillatory output of the cardiorespiratory control system in the medulla oblongata. Figure 1: Massive chat (TrumpSC’s stream); 13 messages / 4 seconds. (of waves) the state of being coherent. [164] In a study of the effects of playing violent and nonviolent video games, it was found that when playing violent video games, the players had lower cardiac coherence levels and higher aggression levels than did nonviolent game players and that higher levels of coherence were negatively related to aggression. We introduced the term physiological coherence to describe the degree of order, harmony and stability in the various rhythmic activities within living systems over any given time period. The various concepts and measurements embraced under the term coherence have become central to fields as diverse as quantum physics, cosmology, physiology and brain and consciousness research. In living systems, there are microlevel systems, molecular machines, protons and electrons, organs and glands, each functioning autonomously, doing very different things at different rates, yet all working together in a complex harmoniously coordinated and synchronized manner. The bottom graphs show the spectrum analysis view of the same data. Simply stated, our body and brain work better , we feel better, and we perform better. Social coherence is reflected as a stable, harmonious alignment of relationships that allow for the efficient flow and utilization of energy and communication required for optimal collective cohesion and action. The search resulted in 95 articles and 20 textbooks. Leadership and coherence : a cognitive approach / "Leadership and Coherence investigates how leaders justify their decisions, and how they bring about Means of Coherence and Cohesion in Spoken and Written Discourse Petra Martinková This paper deals with a linguistic experiment which has been conveyed following the research of coherence and cohesion in authentic written texts and spoken dialogues and monologues. 1 April 2011 Advances in Nursing & Midwifery, “Coherence is the state when the heart, mind, and emotions are in energetic alignment and cooperation,” HeartMath Institute Research Director Dr. Rollin McCraty says. Published While some rhythmic-breathing methods may induce coherence for brief periods, our research indicates that people can achieve extended periods of physiological coherence by actively self-generating positive emotions. Another aspect of coherence relates to the dynamic rhythms produced by a single oscillatory system. Learn More, Exploring the Role of the Heart in Human Performance, An Overview of Research Conducted by the HeartMath Institute. sine wave). In complex globally coherent systems, such as human beings, there is a vast amount of activity at every level of magnification or scale that spans more than two-thirds of the 73 known octaves of the electromagnetic spectrum. Global coherence does not mean everyone or all parts of a system are doing the same thing simultaneously. [165], The coherent state has been correlated with a general sense of well-being and improvements in cognitive, social and physical performance. Thus, the concept of coherence is vitally important for understanding optimal function. Increased entrainment and synchronization between physiological systems. Definition of coherence. Our research is based on spoken narratives to which speakers have additionally provided written versions. Thus, coherence refers to wholeness and global order, where the whole is greater than the sum of its individual parts. [165] It can appear at one level of scale that a given system is operating autonomously, yet it is perfectly coordinated within the whole. At the 300-second mark, the individual did HeartMath’s Freeze Frame Technique and all three systems came into entrainment, meaning the patterns were harmonious instead of scattered and out of sync. PhD candidate, Faculty of Nursing and Midwifery, Tehran University of Medical Sciences, Tehran. clear communication: coherence The term coherence refers to the smooth flow of ideas in a text. "’ Synonyms for coherence include rationality, logicality, intelligibility, soundness, clarity, comprehensibility, logic, articulacy, lucidity and reason. Our perspective is that positive emotions in general, including self-induced positive emotions, shift the entire system into a more globally coherent and harmonious physiological mode, one that is associated with improved system performance, ability to self-regulate and overall wellbeing. ‘Its coherence is helped by the fact that this is also an album with a message.’ ‘But the insurgency lacks the ideological coherence or organization it would need to grow into a more formidable force.’ ‘"We are working towards systemic coherence rather than negating the value of the new certificate. An ordered or constructive distribution of power content within a single waveform; autocoherence (e.g. [5], Social coherence relates to pairs, family units, groups or larger organizations in which a network of relationships exists among individuals who share common interests and objectives.
