(2011). (of waves) the state of being coherent. The afferent pathways from the heart and blood vessels are given more relevance in this model because of the significant degree of afferent cardiovascular input to the brain and the consistent generation of dynamic patterns generated by the heart. Stay in touch with us on our social media pages where we regularly post our latest news, free webinars, tips, exclusive offers and more! 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. Recent independent work has verified this by demonstrating a 75% accuracy rate in detection of discrete emotional states from the HRV signal using a neural network approach for pattern recognition. Although physiological coherence is a natural human state that can occur spontaneously, sustained episodes generally are rare. sine wave). [165] It can appear at one level of scale that a given system is operating autonomously, yet it is perfectly coordinated within the whole. 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. "’ (p. [1448][1]) observed coherence—prolonged persistence of a quantum mechanical phase relationship—at the single-molecule level in light-harvesting complexes from purple bacteria. Entrainment is an example of a physiological state in which there is increased coherence between multiple oscillating systems and also within each system. E-mail: m_salsali@hotmail.com, Print ISSN: 2383-3750Electronic ISSN: 2383-3769. vaismoradi, M., & Salsal, D. mahvash. Meaning, pronunciation, picture, example sentences, grammar, usage notes, synonyms and more. 1 April 2011 PhD candidate, Faculty of Nursing and Midwifery, Tehran University of Medical Sciences, Tehran. Simply stated, our body and brain work better , we feel better, and we perform better. 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. 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. The coherence ratio is formulated as (peak power/[total power – peak power]). Group coherence involves the same principles of global coherence described earlier, but in this context it refers to the synchronized and harmonious order in the relationships between and among the individuals rather than the systems within the body. 1. Our research is based on spoken narratives to which speakers have additionally provided written versions. coherence a cognitive approach leadership research and practice now is not type of challenging means. Order within a singular oscillatory waveform. Another aspect of coherence relates to the dynamic rhythms produced by a single oscillatory system. For any system to produce a meaningful function, it must have the property of global coherence. This gives your essay coherence. Patterns in the activity of cardiovascular afferent neuronal traffic can significantly influence cognitive performance, emotional experience and selfregulatory capacity via inputs to the thalamus, amygdala and other subcortical structures. Leadership and coherence : a cognitive approach / "Leadership and Coherence investigates how leaders justify their decisions, and how they bring about This review study aimed to elucidate one of the important qualitative methodology issues entitled coherence, which is usually undermined during a qualitative study. A detailed discussion on the nature of coherence can be found in two seminal articles. Different factors may cause incoherence in qualitative research, which reduce the rigor and credibility of it. congruity; consistency. In this mode, the body’s systems function with a high degree of efficiency and harmony and natural regenerative processes are facilitated. Thus, the concept of coherence is vitally important for understanding optimal function. 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. of our new e-Booklet: The concept of personality coherence refers to the extent of psychological unity and wholeness embodied within each individual. The Times Literary Supplement (2010) British policing lacks consistency and coherence, with different forces buying different equipment, failing to share information and engaging in petty geographical rivalries. 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. It is important to note, however, these associations are not merely metaphorical. A brief summary of the psychophysiological coherence model is provided below. It is unclear how energy absorbed by pigments in antenna proteins is transferred to the central site of chemical catalysis during photosynthesis. The term autocoherence describes coherent activity within a single system. [163, 168]. It means there will be more than one supporting sentence. Now coherence in quantum mechanics is due to the nature of the wave functions, which describe the underlying stratum of particles and molecules. 1 February 2011, Vaismoradi, M.1 (MSN); Salsali, M.2* (PhD). 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. Get valuable info for free… NEWS & TOOLS Newsletter! a : systematic or logical connection or consistency The essay as a whole lacks coherence. In physics, coherence also is used to describe the coupling and degree of synchronization between different oscillating systems. The oscillatory activity in the heart’s rhythms reflects the status of a network of flexible relationships among dynamic interconnected neural structures in the central and autonomic nervous systems. 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. 12 HeartMath® Tools for Reducing Stress and Staying Balanced Receive your Free copy When functioning in a coherent mode, the heart pulls other biological oscillators into synchronization with its rhythms, thus leading to entrainment of these systems (Figure 4.1). Chat has been a topic of academic research for decades, with early studies dating back to the 1970s [10]. The graphs on the right show how all three systems are entrained at the same frequency after Freeze-Framing. Coherence means a sense of comprehensibility and one’s life making sense. 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. Page 2/34. This is an agreed simple means to specifically acquire guide by on-line. Specifically, heart coherence (also referred to as cardiac coherence or resonance) can be measured by HRV analysis wherein a person’s heartrhythm pattern becomes more ordered and sine wavelike at a frequency of around 0.1 hertz (10 seconds). Vol. a coherent sentence). *Corresponding Author: Mahvash, Salsali. Definition of coherence noun in Oxford Advanced Learner's Dictionary. [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. Coherence is a term of text linguistics used to refer to sense relations between single units (sentences or propositions) of a text. Figure 1: Massive chat (TrumpSC’s stream); 13 messages / 4 seconds. 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. 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, analysis and evaluation undertaken by the researcher. Published Linguistics. Coherence in qualitative research. Coherence definition: Coherence is a state or situation in which all the parts or ideas fit together well so... | Meaning, pronunciation, translations and examples 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. In the present research, we examined the extent to which the narrative, functional, and organismic conceptualizations of personality coherence interrelate, as well as their associations with psychological abilities and personal adjustment. 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, … There are two main strategies that will make your writing coherent: organizing your ideas in a logical order , and connecting them effectively by using transition words and phrases . Information is encoded in the time between intervals (action potentials, pulsatile release of hormones, etc.). These two types are explained below. Synchronization or entrainment between multiple waveforms. Self-induced positive emotions can shift psychophysiological systems into more globally coherent and harmonious orders that are associated with improved performance and overall well-being. question of the paper (identify or carve out your niche: convince the reader that it … 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. Keywords: Coherence, Rigor, Qualitative methodology. Notice how each pattern looks quite different from the others. Scientific Foundation of the HeartMath System, HeartMath Institute is a 501(c)(3) nonprofit, Be a HeartMath Interventions Practitioner. Coherence is when your brain (thoughts and decisions) work hand-in-hand with your heart (emotions) and body (actions you take). Sociologist Raymond Bradley, in collaboration with eminent brain researcher, neurosurgeon and neuroscientist Dr. Karl Pribram, developed a general theory of social communication to explain the patterns of social organization common to most groups and independent of size, culture, degree of formal organization, length of existence or member characteristics. Increased entrainment and synchronization between physiological systems. 3. identification of a knowledge gap; formulation of purpose, hypothesis or research. Global coherence does not mean everyone or all parts of a system are doing the same thing simultaneously. RTD info is our quarterly magazine keeping you in touch with main developments (results, programmes, events, etc). An ordered or constructive distribution of power content within a single waveform; autocoherence (e.g. Cohere definition, to stick together; be united; hold fast, as parts of the same mass: The particles of wet flour cohered to form a paste. The quality of being orderly, consistent and intelligible (e.g. during coherent states increases vagal afferent neuronal traffic, which inhibits thalamic pain pathways at the level of the spinal cord. 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). the property of unity in a written text or a segment of spoken discourse that stems from the links among its … Thus, coherence refers to wholeness and global order, where the whole is greater than the sum of its individual parts. Internal Coherence simply means that consciousness is in control. Several studies in healthy subjects, which helped inform the model, show that during the experience of positive emotions, a sine-wavelike pattern naturally emerges in the heart’s rhythms without any conscious changes in breathing. A growing body of evidence suggests that an energetic field is formed between individuals in groups through which communication among all the group members occurs simultaneously. 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. 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. Put simply, then: cohesion is a formal feature of texts (it gives them their texture), while coherence is "in the eye of the beholder" - that is to say, it is the extent to which the reader (or listener) is able to infer the writer's (or speaker's) communicative intentions. It seems as though the players are in sync and communicating on an unseen energetic level. Hildner et al. A: Good. The search resulted in 95 articles and 20 textbooks. Thus, coherence refers to wholeness and global order, where the whole is greater than the sum of its individual parts. 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. In physics, coherence also is used to describe the coupling and degree of synchronization between different oscillating systems. A constructive waveform produced by two or more waves that are phase- or frequency-locked. Interested in European research? Physiologically, the coherence state is marked by the development of a smooth, sine-wave-like pattern in the heart rate variability trace. Clarity of thought, speech and emotional composure. High heart-rhythm coherence (sine-wavelike rhythmic pattern). how its single constituentsare connected so that the text becomes meaningful for the addressee rather than being a random sequence of unrelated sentences an… Purpose means a sense of core goals, aims, and direction in life. Healthy physiological variability, feedback systems and inhibition are key elements of the complex system for maintaining stability and capacity to appropriately respond to and adapt to changing environments and social demands. By coherence, we simply mean that the chat makes sense to participants and is not experienced as a breakdown, overload, or other difficulty. Professor, Faculty of Nursing and Midwifery, Tehran University of Medical Sciences, Tehran, Iran. 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. b : integration of diverse elements, relationships, or values "The various parts of this … , Physiological or cardiac coherence is reflected in a more ordered sine-wavelike heart-rhythm pattern associated with increased vagally mediated HRV, entrainment between respiration, blood pressure and heart rhythms and increased synchronization between various rhythms in the EEG and cardiac cycle. This means that learning to generate ... and we also have increased mental clarity and improved cognitive function. 2. 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. The authors logged on to some general and specialized search engines as well as conducted a library research in healthcare and social science textbooks to perform an in-depth study regarding coherence in qualitative research. Professor, Faculty of Nursing and Midwifery, Tehran University of Medical Sciences, Tehran, Iran. State-specific emotions are reflected in the patterns of the heart’s rhythms independent of changes in the amount of heart rate variability. [163] This harmonious order signifies a coherent system, whose efficient or optimal function is directly related to the ease and flow in life processes. The left-hand side is the spectral analysis before Freeze-Framing. Text analysis focussing on coherence is primarily concerned with the construction and configuration of sense in the text i.e. The bottom graphs show the spectrum analysis view of the same data. [142, 143]. In addition, in the long run, it results in uncontrolled methodological diversities and inability to define criteria to judge qualitative research reports. 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. Our research also suggests that the time intervals between heartbeats (HRV) also encode information, which is communicated across multiple systems and helps synchronize the system as whole. [5, 59], The coherence model includes specific approaches for quantifying the various types of physiological coherence measures, such as cross-coherence (frequency entrainment between respiration, BP and heart rhythms), or synchronization among systems (e.g., synchronization between various EEG rhythms and the cardiac cycle), autocoherence (stability of a single waveform such as respiration or HRV patterns) and system resonance. [165], The coherent state has been correlated with a general sense of well-being and improvements in cognitive, social and physical performance. The most common dictionary definition is the quality of being logically integrated, consistent and intelligible, as in a coherent statement. These are sinusoidal functions which means they not only have an amplitude ( a measure) but also a phase. For example, information is encoded in the time interval between action potentials in the nervous system and patterns in the pulsatile release of hormones. 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. 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. Figure 4.1 The top graphs show an individual’s heart rate variability, pulse transit time and respiration patterns for 10 minutes. 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. It is available in English, French and German. In other words, there is a literal group "field" that connects all the members. The present study is one of a few that have used ‘sense of coherence’ (SOC) as a dependent variable in an explanatory model. [5] A coherent heart rhythm is defined as a relatively harmonic, sine-wavelike signal with a very narrow, high-amplitude peak in the lowfrequency (LF) region of the HRV power spectrum with no major peaks in the very-low-frequency (VLF) or high-frequency (HF) regions. “Coherence is the state when the heart, mind, and emotions are in energetic alignment and cooperation,” HeartMath Institute Research Director Dr. Rollin McCraty says. [159] A related meaning is the logical, orderly and aesthetically consistent relationship among parts. Synonyms for coherence include rationality, logicality, intelligibility, soundness, clarity, comprehensibility, logic, articulacy, lucidity and reason. Coherence A Cognitive Approach Leadership Research And Practice community so both leader and led are guided by a mutual purpose. [159] Coherence always implies correlations, connectedness, consistency and efficient energy utilization. It is a state of unity between your mind, body, and spirit. [160] This type of coherence is called cross-coherence and is the type of coherence that most scientists think of when they use the term. The functional status of the underlying psychophysiological system determines the range of one’s ability to adapt to challenges, self-regulate and engage in harmonious social relationships. ‘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. 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. 20 No. Definition of coherence. teaching and research institutions in France or abroad, or from public or private research centers. The template of this website is designed by, Shahid Beheshti University of Medical Science, Publication Ethics and Research Misconduct, Ethical Considerations for Human Subjects. The principles, however, remain the same: In a coherent team, there is freedom for the individual members to do their part and thrive while maintaining cohesion and resonance within the group’s intent and goals. 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]. 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 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. In humans, this includes our physical, mental, emotional and social systems. In spite of the importance of coherence in qualitative methodology, 23 articles and 7 textbooks had more content regarding the subject, which were employed to write this paper. However, the energy efficiency and degree of coordinated action of any given system can vary widely and does not necessarily result in a coherent output or flow of behavior.

In physiology, cross-coherence occurs when two or more of the body’s oscillatory systems, such as respiration and heart rhythms, become entrained and operate at the same frequency. Purpose means a sense of core goals, aims, and direction in life. 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. Coherence always implies correlations, connectedness, consistency and efficient energy utilization. Researchers seem to have two main ways to understand what meaning in life means: coherence and pur-pose, with a third way, significance, gaining increasing attention. 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]. clear communication: coherence The term coherence refers to the smooth flow of ideas in a text. 70 (2011), In contrast, an erratic, discordant pattern of activity denotes an incoherent system whose function reflects stress and inefficient utilization of energy in life processes. 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. Coherence in conversations and in texts can be partially characterized by a set of ... phrases to be coreferential. It is found by the ratio of the cross power spectral density divided by the … Due to these relations, the text appears to be logically and semantically consistent for the reader-hearer. And what if the highest goal achievable, as a result, is simply the internal coherence of a speculative argument? 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). 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. 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. There are two types of coherence namely, temporal coherence and spatial coherence. Advances in Nursing & Midwifery, The study of both cohesion and coherence is a favourite field of research among linguists. Increased "rate of change" in cardiac sensory neurons (transducing BP, rhythm, etc.) Page 45-53 See more. When coherence is increased in a system that is coupled to other systems, it can pull the other systems into increased synchronization and more efficient function. Physiological coherence is assessed by identifying the maximum peak in the 0.04 to 0.26 hertz range of the HRV power spectrum, calculating the integral in a window 0.030 hertzwide, centered on the highest peak in that region and then calculating the total power of the entire spectrum. [59] Coherence has several related definitions, all of which are applicable to the study of human physiology, social interactions and global affairs. Physics, Optics. Coherence means a sense of comprehensibility and one’s life making sense. 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.
