Perseverative cognition [1] [2] is a collective term in psychology for continuous thinking about negative events [3] in the past or in the future (e.g. worry, rumination and brooding, but also mind wandering about negative topics [4] [5] ).
It has been shown to have physiological effects, such as increased heart rate, blood pressure and cortisol, in daily life as well as under controlled laboratory conditions. [6] [7] Because of these physiological effects, the psychological concept of perseverative cognition helps to explain how psychological stress, such as work stress and marital stress, leads to disease, such as cardiovascular disease.
The definition of perseverative cognition is: "the repeated or chronic activation of the cognitive representation of one or more psychological stressors". [2] [8] Worry, rumination and all other forms of thoughts (cognition), about stressful events that have happened or might happen, fall under the definition of perseverative cognition. 'Just thinking about your problems, without calling it worrying or rumination', is also perseverative cognition, as is mind wandering when it concerns negative topics. [4] [5] There is a large body of knowledge about the typical constituents of perseverative cognition, such as worry, rumination, repetitive thinking and (negative) mind wandering (reviewed in Watkins, 2008 [3] ). Perseverative cognition may partly be unconscious. [9] [10] Just as people are not aware of the larger part of their thoughts (cognition), [11] [12] they may also not be aware they continue to think about stressors.
The perseverative cognition hypothesis [2] holds that stressful events begin to affect people's health when they think about them repetitively or continuously (that is, 'perseverate cognitively').
Stressful events and the direct physiological responses to them are often too short in duration to cause bodily harm. But people can have continuing thoughts about events from the past, or about potential future events, and the body reacts to the repeated thoughts (perseverative cognition) with prolonged physiological stress responses. Therefore, it is the perseverative cognition, and not the stressors that can eventually lead to disease. In scientific terms, it is said that perseverative cognition is a mediator of the detrimental effects of stress on one's health. Since its publication scientific evidence for this hypothesis has been accumulating. [8] [13] [14] [15]
Perseverative cognition is involved with a “stress-disease link". [1] Further, it is the thinking about the stress, or rather the obsessing over it, that establishes a link between stress and disease. Perseverative cognition also focuses on the effects that worrying over anticipated events have on the physical body and mind. [2] This could suggest that obsessive worrying over past events or the future could lead to physical issues.
There are some physical evidences of the effects of perseverative cognition, as noted in an analysis article. [7] The article found that cortisol levels, as well as the average heart rates of individuals, were higher when perseverative cognitive processes were present. [7] Another article [8] says that “worrying about stressful events increases the total amount of time that stress has a ‘wear and tear’ effect on the human body.” Studies [16] have been done that show links between cognitive perseverance and increased heart rates. The consistent, ruminating thoughts circulating in one's mind could lead to physical responses.
In another article, it is discussed that perseverative cognition increases heart rate, and also impacts parts of the brain, notably in the prefrontal and amygdala areas. [16] There is a connection between the brain and the heart when it comes to perseverative cognition. When present, it impacts not only mental facilities, but also physical components. [16] One article describes the physical components as a response to the thoughts, “as if the individual were facing an external stressor”. [17] The article also talks about how obsessive thoughts of worry lead to greater depression. Cognitive perseverance leads to multiple issues, ranging from mood to heart rate.
Cognitive perseverance not only impacts mental and physical processing, but it also has the possibility of impacting sleep, as explored in one article. [18] In this article, the impact of obsessive worrying regarding jobs, therefore creating perseverative cognition, on sleep was explored. They found that there was a correlation between excessive job centered perseverative cognition and a lack of good sleep. Perseverative cognition impacts several parts of life. Another article [19] talks about how poor sleep could happen when one had perseverative cognition. The article uses the term mind wandering to talk about “persistent and repetitive” thoughts [20] and correlates with other mental disorders. Perseverative cognition can affect more than physical components, as stated earlier. The same article [21] also talked about how mental rigidity ties in with perseverative cognition and impacts individuals in multiple ways.
In addition, perseverative cognition has potential to make other mental illnesses worse. In another article, on its effect on PTSD, [20] it was found that with severe PTSD and the perseverative cognition, it correlated with less recovery regarding cardiovascular disease.
Cognitive psychology is the scientific study of mental processes such as attention, language use, memory, perception, problem solving, creativity, and reasoning.
Psychology is the scientific study of mind and behavior. Psychology includes the study of conscious and unconscious phenomena, including feelings and thoughts. It is an academic discipline of immense scope, crossing the boundaries between the natural and social sciences. Psychologists seek an understanding of the emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups. Ψ (psi), the first letter of the Greek word psyche from which the term psychology is derived, is commonly associated with the science.
Psychophysiology is the branch of psychology that is concerned with the physiological bases of psychological processes. While psychophysiology was a general broad field of research in the 1960s and 1970s, it has now become quite specialized, based on methods, topic of studies and scientific traditions. Methods vary as combinations of electrophysiological methods, neuroimaging, and neurochemistry. Topics have branched into subspecializations such as social, sport, cognitive, cardiovascular, clinical and other branches of psychophysiology.
In the field of psychology, cognitive dissonance is the perception of contradictory information, and the mental toll of it. Relevant items of information include a person's actions, feelings, ideas, beliefs, values, and things in the environment. Cognitive dissonance is typically experienced as psychological stress when persons participate in an action that goes against one or more of those things. According to this theory, when two actions or ideas are not psychologically consistent with each other, people do all in their power to change them until they become consistent. The discomfort is triggered by the person's belief clashing with new information perceived, wherein the individual tries to find a way to resolve the contradiction to reduce their discomfort.
Introspection is the examination of one's own conscious thoughts and feelings. In psychology, the process of introspection relies on the observation of one's mental state, while in a spiritual context it may refer to the examination of one's soul. Introspection is closely related to human self-reflection and self-discovery and is contrasted with external observation.
Social cognition is a sub-topic of various branches of psychology that focuses on how people process, store, and apply information about other people and social situations. It focuses on the role that cognitive processes play in social interactions.
Daydreaming is the stream of consciousness that detaches from current, external tasks when attention drifts to a more personal and internal direction. This phenomenon is common in people's daily life shown by a large-scale study in which participants spend 47% of their waking time on average on daydreaming. There are various names of this phenomenon including mind wandering, fantasy, spontaneous thoughts, etc. Daydreaming is the term used by Jerome L. Singer whose research laid the foundation for nearly all the subsequent research today. The terminologies assigned by researchers today puts challenges on identifying the common features of daydreaming, and on building collective work among researchers.
Mindfulness is the practice of purposely bringing one's attention to the present-moment experience without evaluation, a skill one develops through meditation or other training. Mindfulness derives from sati, a significant element of Hindu and Buddhist traditions, and is based on Zen, Vipassanā, and Tibetan meditation techniques. Though definitions and techniques of mindfulness are wide-ranging, Buddhist traditions explain what constitutes mindfulness such as how past, present and future moments arise and cease as momentary sense impressions and mental phenomena. Individuals who have contributed to the popularity of mindfulness in the modern Western context include Thích Nhất Hạnh, Herbert Benson, Jon Kabat-Zinn, Richard J. Davidson, and Sam Harris.
Worry refers to the thoughts, images, emotions, and actions of a negative nature in a repetitive, uncontrollable manner that results from a proactive cognitive risk analysis made to avoid or solve anticipated potential threats and their potential consequences.
Music psychology, or the psychology of music, may be regarded as a branch of both psychology and musicology. It aims to explain and understand musical behaviour and experience, including the processes through which music is perceived, created, responded to, and incorporated into everyday life. Modern music psychology is primarily empirical; its knowledge tends to advance on the basis of interpretations of data collected by systematic observation of and interaction with human participants. Music psychology is a field of research with practical relevance for many areas, including music performance, composition, education, criticism, and therapy, as well as investigations of human attitude, skill, performance, intelligence, creativity, and social behavior.
Mindfulness-based cognitive therapy (MBCT) is an approach to psychotherapy that uses cognitive behavioral therapy (CBT) methods in collaboration with mindfulness meditative practices and similar psychological strategies. The origins to its conception and creation can be traced back to the traditional approaches from East Asian formative and functional medicine, philosophy and spirituality, birthed from the basic underlying tenets from classical Taoist, Buddhist and Traditional Chinese medical texts, doctrine and teachings.
Mind-wandering is a broad term with no currently universal definition. According to McMillan, Kaufmann and Singer (2013) mind-wandering consists of 3 different subtypes: positive constructive daydreaming, guilty fear of failure, and poor attentional control. Whereas Smallwood and Schooler (2015) suggest that mind-wandering consists of thoughts that are task-unrelated and stimulus-independent. In general, a folk explanation of mind-wandering could be described as the experience of thoughts not remaining on a single topic for a long period of time, particularly when people are engaged in an attention-demanding task.
Test anxiety is a combination of physiological over-arousal, tension and somatic symptoms, along with worry, dread, fear of failure, and catastrophizing, that occur before or during test situations. It is a physiological condition in which people experience extreme stress, anxiety, and discomfort during and/or before taking a test. This anxiety creates significant barriers to learning and performance. Research suggests that high levels of emotional distress have a direct correlation to reduced academic performance and higher overall student drop-out rates. Test anxiety can have broader consequences, negatively affecting a student's social, emotional and behavioural development, as well as their feelings about themselves and school.
The psychological and physiological effects of meditation have been studied. In recent years, studies of meditation have increasingly involved the use of modern instruments, such as fMRI and EEG, which are able to observe brain physiology and neural activity in living subjects, either during the act of meditation itself or before and after meditation. Correlations can thus be established between meditative practices and brain structure or function.
Chronic stress is the physiological or psychological response induced by a long-term internal or external stressor. The stressor, either physically present or recollected, will produce the same effect and trigger a chronic stress response. There is a wide range of chronic stressors, but most entail relatively prolonged problems, conflicts and threats that people encounter on a daily basis. And several chronic stressors, including "neighbourhood environment, financial strain, interpersonal stress, work stress and caregiving.", have been identified as associated with disease and mortality.
Emotional self-regulation or emotion regulation is the ability to respond to the ongoing demands of experience with the range of emotions in a manner that is socially tolerable and sufficiently flexible to permit spontaneous reactions as well as the ability to delay spontaneous reactions as needed. It can also be defined as extrinsic and intrinsic processes responsible for monitoring, evaluating, and modifying emotional reactions. Emotional self-regulation belongs to the broader set of emotion regulation processes, which includes both the regulation of one's own feelings and the regulation of other people's feelings.
Rumination is the focused attention on the symptoms of one's distress, and on its possible causes and consequences, as opposed to its solutions, according to the Response Styles Theory proposed by Nolen-Hoeksema (1998).
Mindfulness-based stress reduction (MBSR) is an eight-week evidence-based program that offers secular, intensive mindfulness training to assist people with stress, anxiety, depression and pain. Developed at the University of Massachusetts Medical Center in the 1970s by Professor Jon Kabat-Zinn, MBSR uses a combination of mindfulness meditation, body awareness, yoga and exploration of patterns of behaviour, thinking, feeling and action. Mindfulness can be understood as the non-judgmental acceptance and investigation of present experience, including body sensations, internal mental states, thoughts, emotions, impulses and memories, in order to reduce suffering or distress and to increase well-being. Mindfulness meditation is a method by which attention skills are cultivated, emotional regulation is developed, and rumination and worry are significantly reduced. During the past decades, mindfulness meditation has been the subject of more controlled clinical research, which suggests its potential beneficial effects for mental health, as well as physical health. While MBSR has its roots in Buddhist wisdom teachings, the program itself is secular. The MBSR program is described in detail in Kabat-Zinn's 1990 book Full Catastrophe Living.
In psychology, stress is a feeling of emotional strain and pressure. Stress is a type of psychological pain. Small amounts of stress may be beneficial, as it can improve athletic performance, motivation and reaction to the environment. Excessive amounts of stress, however, can increase the risk of strokes, heart attacks, ulcers, and mental illnesses such as depression and also aggravation of a pre-existing condition.
Metacognitive therapy (MCT) is a psychotherapy focused on modifying metacognitive beliefs that perpetuate states of worry, rumination and attention fixation. It was created by Adrian Wells based on an information processing model by Wells and Gerald Matthews. It is supported by scientific evidence from a large number of studies.
