Post-traumatic Stress Disorder In Children And Adolescents
Post-traumatic stress disorder (PTSD) in children and adolescents or pediatric PTSD refers to pediatric cases of post-traumatic stress disorder. Children and adolescents may encounter highly stressful experiences that can significantly impact their thoughts and emotions. While most children recover effectively from such events, some who experience severe stress can be affected long-term. This prolonged impact can stem from direct exposure to trauma or from witnessing traumatic events involving others. When children develop persistent symptoms (lasting over one month) due to such stress, which cause significant distress or interfere with their daily functioning and relationships, they may be diagnosed with PTSD. Signs and Symptoms Children experiencing PTSD may exhibit a range of signs and symptoms, which vary depending on their age and developmental stage. These commonly include: * Re-experiencing the traumatic event: This can manifest as intrusive thoughts, flashbacks, or re ...

Pediatric
Pediatrics (American English) also spelled paediatrics (British English), is the branch of medicine that involves the medical care of infants, children, adolescents, and young adults. In the United Kingdom, pediatrics covers many of their youth until the age of 18. The American Academy of Pediatrics recommends people seek pediatric care through the age of 21, but some pediatric subspecialists continue to care for adults up to 25. Worldwide age limits of pediatrics have been trending upward year after year. A medical doctor who specializes in this area is known as a pediatrician, or paediatrician. The word ''pediatrics'' and its cognates mean "healer of children", derived from the two Greek words: (''pais'' "child") and (''iatros'' "doctor, healer"). Pediatricians work in clinics, research centers, universities, general hospitals and children's hospitals, including those who practice pediatric subspecialties (e.g. neonatology requires resources available in a NICU).

Irritability
Irritability is the excitatory ability that living organisms have to respond to changes in their environment. The term is used for both the physiological reaction to stimuli and for the pathological, abnormal or excessive sensitivity to stimuli. When reflecting human emotion and behavior, it is commonly defined as the tendency to react to stimuli with negative affective states (especially anger) and temper outbursts, which can be aggressive. Distressing or impairing irritability is important from a mental health perspective as a common symptom of concern and predictor of clinical outcomes. Definition Irritability is the excitatory ability that living organisms have to respond to changes in their environment. The term is used for both the physiological reaction to stimuli and for the pathological, abnormal or excessive sensitivity to stimuli. Irritability can be demonstrated in behavioral responses to both physiological and behavioral stimuli, including environmental, situ ...

Depersonalization
Depersonalization is a dissociative phenomenon characterized by a subjective feeling of detachment from oneself, manifesting as a sense of disconnection from one's thoughts, emotions, sensations, or actions, and often accompanied by a feeling of observing oneself from an external perspective. Subjects perceive that the world has become vague, dreamlike, surreal, or strange, leading to a diminished sense of individuality or identity. Those affected often feel as though they are observing the world from a distance, as if separated by a barrier "behind glass". They maintain insight into the subjective nature of their experience, recognizing that it pertains to their own perception rather than altering objective reality. This distinction between subjective experience and objective reality distinguishes depersonalization from delusions, where individuals firmly believe in false perceptions as genuine truths. Depersonalization is also distinct from derealization, which involves a sense ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dissociative Disorder
Dissociative disorders (DDs) are a range of conditions characterized by significant disruptions or fragmentation "in the normal integration of consciousness, memory, identity, emotion, perception, body representation, motor control, and behavior." Dissociative disorders involve involuntary Dissociation (psychology), dissociation as an unconscious Defence mechanism, defense mechanism, wherein the individual with a dissociative disorder experiences separation in these areas as a means to protect against traumatic stress. Some dissociative disorders are caused by major psychological trauma, though the onset of depersonalization-derealization disorder may be preceded by less severe stress, by the influence of psychoactive substances, or occur without any discernible trigger. The dissociative disorders listed in the American Psychiatric Association's ''Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition'' (DSM-5) are as follows: * Dissociative identity disorder (DID, ...

Metacognition
Metacognition is an awareness of one's thought processes and an understanding of the patterns behind them. The term comes from the root word ''Meta (prefix), meta'', meaning "beyond", or "on top of".Metcalfe, J., & Shimamura, A. P. (1994). ''Metacognition: knowing about knowing''. Cambridge, MA: MIT Press. Metacognition can take many forms, such as reflecting on one's ways of thinking, and knowing when and how oneself and others use particular strategies for Problem solving, problem-solving. There are generally two components of metacognition: (1) cognitive conceptions and (2) cognitive regulation system.Hartelt, T. & Martens, H. (2024). Influence of self-assessment and conditional metaconceptual knowledge on students' self-regulation of intuitive and scientific conceptions of evolution. Journal of Research in Science Teaching, 61(5), 1134–1180. https://doi.org/10.1002/tea.21938 Research has shown that both components of metacognition play key roles in metaconceptual knowledge and ...

Insight
Insight is the understanding of a specific causality, cause and effect within a particular context. The term insight can have several related meanings: *a piece of information *the act or result of understanding the inner nature of things or of seeing Intuition (knowledge), intuitively (called in Greek) *an introspection *the power of acute observation and Deductive reasoning, deduction, discernment, and perception, called intellection or *an understanding of cause and effect based on the identification of relationships and behaviors within a model, system, context, or scenario (see artificial intelligence) An insight that manifests itself suddenly, such as understanding how to solve a difficult problem, is sometimes called by the German language, German word . The term was coined by the German psychologist and theoretical linguist Karl Bühler. It is also known as an epiphany (feeling), epiphany, Eureka effect, eureka moment, or (for crossword solvers) the penny dropping moment ...

Attention-deficit/hyperactivity Disorder
Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterised by symptoms of inattention, hyperactivity, impulsivity, and emotional dysregulation that are excessive and pervasive, impairing in multiple contexts, and developmentally inappropriate. ADHD symptoms arise from executive dysfunction. Impairments resulting from deficits in self-regulation such as time management, inhibition, task initiation, and sustained attention can include poor professional performance, relationship difficulties, and numerous health risks, collectively predisposing to a diminished quality of life and a reduction in life expectancy. As a consequence, the disorder costs society hundreds of billions of US dollars each year, worldwide. It is associated with other mental disorders as well as non-psychiatric disorders, which can cause additional impairment. While ADHD involves a lack of sustained attention to tasks, inhibitory deficits also can lead to difficulty i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Attention
Attention or focus, is the concentration of awareness on some phenomenon to the exclusion of other stimuli. It is the selective concentration on discrete information, either subjectively or objectively. William James (1890) wrote that "Attention is the taking possession by the mind, in clear and vivid form, of one out of what seem several simultaneously possible objects or trains of thought. Focalization, concentration, of consciousness are of its essence." Attention has also been described as the allocation of limited cognitive processing resources. Attention is manifested by an attentional bottleneck, in terms of the amount of data the brain can process each second; for example, in human vision, less than 1% of the visual input data stream of 1MByte/sec can enter the bottleneck, leading to inattentional blindness. Attention remains a crucial area of investigation within education, psychology, neuroscience, cognitive neuroscience, and neuropsychology. Areas of activ ...

Fidgeting
Fidgeting is the act of moving about restlessly in a way that is not ( socially recognized as) essential to ongoing tasks or events. Fidgeting may involve playing with one's fingers, hair, or personal objects (e.g. glasses, pens or items of clothing). In this sense, it may be considered twiddling or fiddling. Fidgeting is commonly used as a label for unexplained or subconscious activities and postural movements that people perform while seated or standing idle. A common act of fidgeting is to bounce one's leg repeatedly. Rings are another common focus of fidgeting; variations include ring spinning, twirling or rolling along a table. Classrooms are sites of fidgeting, and traditionally teachers and students have viewed fidgeting as a sign of diminished attention. Toys have been invented to help with fidgeting. These fidget toys include fidget spinners. Causes and effects Fidgeting may be a result of nervousness, frustration, agitation, boredom, ADHD, excitement, or a combin ...

Avoidance Coping
In psychology, avoidance coping is a coping mechanism and form of experiential avoidance. It is characterized by a person's efforts, conscious or unconscious, to avoid dealing with a stressor in order to protect oneself from the difficulties the stressor presents. Avoidance coping can lead to substance abuse, Solitude, social withdrawal, and other forms of escapism. High levels of avoidance behaviors may lead to a diagnosis of avoidant personality disorder, though not everyone who displays such behaviors meets the definition of having this disorder. Avoidance coping is also a symptom of post-traumatic stress disorder and related to symptoms of depression and anxiety. Additionally, avoidance coping is part of the approach-avoidance conflict theory introduced by psychologist Kurt Lewin. Literature on coping often classifies coping strategies into two broad categories: approach/active coping and avoidance/passive coping. Approach coping includes behaviors that attempt to reduce stress ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Startle Response
In animals, including humans, the startle response is a largely unconscious defensive response to sudden or threatening Stimulus (physiology), stimuli, such as sudden noise or sharp movement, and is associated with negative Affect (psychology), affect.Rammirez-Moreno, David. "A computational model for the modulation of the prepulse inhibition of the acoustic startle reflex". ''Biological Cybernetics'', 2012, p. 169 Usually the onset of the startle response is a startle reflex reaction. The startle reflex is a brainstem reflectory reaction (reflex) that serves to protect vulnerable parts, such as the back of the neck (whole-body startle) and the eyes (eyeblink) and Fight-or-flight response, facilitates escape from sudden stimuli. It is found across many different species, throughout all stages of life. A variety of responses may occur depending on the affected individual's emotional state, body posture, preparation for execution of a motor task, or other activities. The startle respo ...

Vigilance (psychology)
In modern psychology, vigilance, also termed sustained concentration, is defined as the ability to maintain concentrated attention over prolonged periods of time. During this time, the person attempts to detect the appearance of a particular target stimulus. The individual watches for a signal stimulus that may occur at an unknown time. The study of vigilance has expanded since the 1940s mainly due to the increased interaction of people with machines for applications involving monitoring and detection of rare events and weak signals. Such applications include air traffic control, inspection and quality control, automated navigation, military and border surveillance, and lifeguarding. Origins of research The systematic study of vigilance was initiated by Norman Mackworth during World War II. Mackworth authored "The breakdown of vigilance during prolonged visual search" in 1948 and this paper is the seminal publication on vigilance. Mackworth's 1948 study investigated the tendency ...
