coherence simply means in research

[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.

Scientific Foundation of the HeartMath System, HeartMath Institute is a 501(c)(3) nonprofit, Be a HeartMath Interventions Practitioner. Synchronization or entrainment between multiple waveforms. 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. And what if the highest goal achievable, as a result, is simply the internal coherence of a speculative argument? 1 April 2011 Thus, coherence refers to wholeness and global order, where the whole is greater than the sum of its individual parts. (2011). 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. A constructive waveform produced by two or more waves that are phase- or frequency-locked. Information is encoded in the time between intervals (action potentials, pulsatile release of hormones, etc.). This review study aimed to elucidate one of the important qualitative methodology issues entitled coherence, which is usually undermined during a qualitative study. Notice how each pattern looks quite different from the others. 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. (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. Coherence in qualitative research. Coherence always implies correlations, connectedness, consistency and efficient energy utilization. [159] A related meaning is the logical, orderly and aesthetically consistent relationship among parts. The gathered data were classified into 4 categories: the definition of coherence; the proofs for incoherence in qualitative methodology; the causes of incoherence; and, finally, the strategies for coherence improvement in qualitative methodology. It is available in English, French and German. In this mode, the body’s systems function with a high degree of efficiency and harmony and natural regenerative processes are facilitated. The feelings we label as positive actually reflect body states that are coherent, meaning "the regulation of life processes becomes efficient, or even optimal, free-flowing and easy,"[160] and the feelings we label as "negative," such as anger, anxiety and frustration are examples of incoherent states. ‘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. the property of unity in a written text or a segment of spoken discourse that stems from the links among its … There are two types of coherence namely, temporal coherence and spatial coherence. 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. These two types are explained below. Keywords: Coherence, Rigor, Qualitative methodology. sine wave). Coherence in conversations and in texts can be partially characterized by a set of ... phrases to be coreferential. 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. This is an agreed simple means to specifically acquire guide by on-line. Thus, coherence refers to wholeness and global order, where the whole is greater than the sum of its individual parts. 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. [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. State-specific emotions are reflected in the patterns of the heart’s rhythms independent of changes in the amount of heart rate variability. 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). Using referents and synonyms as we’ve seen will help you achieve cohesion. 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. 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. 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. 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. 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. teaching and research institutions in France or abroad, or from public or private research centers. The search resulted in 95 articles and 20 textbooks. See more. Increased "rate of change" in cardiac sensory neurons (transducing BP, rhythm, etc.) 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. Both concepts, traditionally connected with the reading process, have become an important tool in order to teach students how to write a text. 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. 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. Linguistics. 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. [165] It can appear at one level of scale that a given system is operating autonomously, yet it is perfectly coordinated within the whole. [142, 143]. [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. 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. For example, information is encoded in the time interval between action potentials in the nervous system and patterns in the pulsatile release of hormones. 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. 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. Get valuable info for free… NEWS & TOOLS Newsletter! 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. [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. Page 2/34. 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. The bottom graphs show the spectrum analysis view of the same data. 1 February 2011, Vaismoradi, M.1 (MSN); Salsali, M.2* (PhD). Another aspect of coherence relates to the dynamic rhythms produced by a single oscillatory system. 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. 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. Interested in European research? 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. a : systematic or logical connection or consistency The essay as a whole lacks coherence. "’ 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. 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. coherence a cognitive approach leadership research and practice now is not type of challenging means. 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. [163, 168]. By coherence, we simply mean that the chat makes sense to participants and is not experienced as a breakdown, overload, or other difficulty. This gives your essay coherence. The most common dictionary definition is the quality of being logically integrated, consistent and intelligible, as in a coherent statement. Internal Coherence simply means that consciousness is in control. 3. identification of a knowledge gap; formulation of purpose, hypothesis or research. The coherence model predicts that different emotions are reflected in state-specific patterns in the heart’s rhythms[5] independent of the amount of HRV/HR (Figure 4.2). [159] Coherence always implies correlations, connectedness, consistency and efficient energy utilization. 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. The template of this website is designed by, Shahid Beheshti University of Medical Science, Publication Ethics and Research Misconduct, Ethical Considerations for Human Subjects. Entrainment is an example of a physiological state in which there is increased coherence between multiple oscillating systems and also within each system. 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. 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. Increased entrainment and synchronization between physiological systems. 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. , Physics, Optics. 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 . Coherence means a sense of comprehensibility and one’s life making sense. It is unclear how energy absorbed by pigments in antenna proteins is transferred to the central site of chemical catalysis during photosynthesis. 70 (2011), RTD info is our quarterly magazine keeping you in touch with main developments (results, programmes, events, etc). Definition of coherence. The coherence ratio is formulated as (peak power/[total power – peak power]). 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). Receive your Free copy 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. Due to these relations, the text appears to be logically and semantically consistent for the reader-hearer. *Corresponding Author: Mahvash, Salsali. The present study is one of a few that have used ‘sense of coherence’ (SOC) as a dependent variable in an explanatory model. 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. A brief summary of the psychophysiological coherence model is provided below. Coherence is a term of text linguistics used to refer to sense relations between single units (sentences or propositions) of a text. of our new e-Booklet: Chat has been a topic of academic research for decades, with early studies dating back to the 1970s [10]. 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. Professor, Faculty of Nursing and Midwifery, Tehran University of Medical Sciences, Tehran, Iran. 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. 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. Figure 4.1 The top graphs show an individual’s heart rate variability, pulse transit time and respiration patterns for 10 minutes. Purpose means a sense of core goals, aims, and direction in life. Order within a singular oscillatory waveform. Clarity of thought, speech and emotional composure. Now coherence in quantum mechanics is due to the nature of the wave functions, which describe the underlying stratum of particles and molecules. It is found by the ratio of the cross power spectral density divided by the … Text analysis focussing on coherence is primarily concerned with the construction and configuration of sense in the text i.e. 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]. 12 HeartMath® Tools for Reducing Stress and Staying Balanced L’archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d’enseignement et de recherche français ou étrangers, des laboratoires publics ou privés. Coherence A Cognitive Approach Leadership Research And Practice community so both leader and led are guided by a mutual purpose. It is important to note, however, these associations are not merely metaphorical. Purpose means a sense of core goals, aims, and direction in life. In contrast, an erratic, discordant pattern of activity denotes an incoherent system whose function reflects stress and inefficient utilization of energy in life processes. [165], The coherent state has been correlated with a general sense of well-being and improvements in cognitive, social and physical performance. (of waves) the state of being coherent. Leadership and coherence : a cognitive approach / "Leadership and Coherence investigates how leaders justify their decisions, and how they bring about A detailed discussion on the nature of coherence can be found in two seminal articles. 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. how its single constituentsare connected so that the text becomes meaningful for the addressee rather than being a random sequence of unrelated sentences an… Physiologically, the coherence state is marked by the development of a smooth, sine-wave-like pattern in the heart rate variability trace. 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. It means there will be more than one supporting sentence. The study of both cohesion and coherence is a favourite field of research among linguists. [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. It seems as though the players are in sync and communicating on an unseen energetic level. 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.
