Executive Dysfunction
In psychology and neuroscience, executive dysfunction, or executive function deficit, is a disruption to the efficacy of the executive functions, which is a group of cognitive processes that regulate, control, and manage other cognitive processes. Executive dysfunction can refer to both neurocognitive deficits and behavioural symptoms. It is implicated in numerous neurological and mental disorders, as well as short-term and long-term changes in non-clinical executive control. It can encompass other cognitive difficulties like planning, organizing, initiating tasks, and regulating emotions. It is a core characteristic of attention deficit hyperactivity disorder (ADHD) and can elucidate numerous other recognized symptoms. Extreme executive dysfunction is the cardinal feature of dysexecutive syndrome. Overview Executive functioning is a theoretical construct representing a domain of cognitive processes that regulate, control, and manage other cognitive processes. Executive fun ...

Psychology
Psychology is the scientific study of mind and behavior. Its subject matter includes the behavior of humans and nonhumans, both consciousness, conscious and Unconscious mind, unconscious phenomena, and mental processes such as thoughts, feelings, and motivation, motives. Psychology is an academic discipline of immense scope, crossing the boundaries between the Natural science, natural and social sciences. Biological psychologists seek an understanding of the Emergence, emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups.Hockenbury & Hockenbury. Psychology. Worth Publishers, 2010. A professional practitioner or researcher involved in the discipline is called a psychologist. Some psychologists can also be classified as Behavioural sciences, behavioral or Cognitive science, cognitive scientists. Some psychologists attempt to understand the role of mental functions in i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Set Shifting
Cognitive flexibility is an intrinsic property of a cognitive system often associated with the mental ability to adjust its activity and content, switch between different task rules and corresponding behavioral responses, maintain multiple concepts simultaneously and shift internal attention between them. The term ''cognitive flexibility'' is traditionally used to refer to one of the executive functions. In this sense, it can be seen as neural underpinnings of adaptive and flexible behavior. Most flexibility tests were developed under this assumption several decades ago. Nowadays, cognitive flexibility can also be referred to as a set of properties of the brain that facilitate flexible yet relevant switching between functional brain states. Cognitive flexibility varies during the lifespan of an individual. In addition, certain conditions such as obsessive–compulsive disorder are associated with reduced cognitive flexibility. Since cognitive flexibility is a vital component of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Episodic Memory
Episodic memory is the memory of everyday events (such as times, location geography, associated emotions, and other contextual information) that can be explicitly stated or conjured. It is the collection of past personal experiences that occurred at particular times and places; for example, the party on one's 7th birthday. Along with semantic memory, it comprises the category of explicit memory, one of the two major divisions of long-term memory (the other being implicit memory). The term "episodic memory" was coined by Endel Tulving in 1972, referring to the distinction between knowing and remembering: ''knowing'' is factual recollection (semantic) whereas ''remembering'' is a feeling that is located in the past (episodic). One of the main components of episodic memory is the process of recollection, which elicits the retrieval of contextual information pertaining to a specific event or experience that has occurred. Tulving seminally defined three key properties of episodi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Social Interaction
A social relation is the fundamental unit of analysis within the social sciences, and describes any voluntary or involuntary interpersonal relationship between two or more conspecifics within and/or between groups. The group can be a language or kinship group, a social institution or organization, an economic class, a nation, or gender. Social relations are derived from human behavioral ecology, and, as an aggregate, form a coherent social structure whose constituent parts are best understood relative to each other and to the social ecosystem as a whole. History Early inquiries into the nature of social relations featured in the work of sociologists such as Max Weber in his theory of social action, where social relationships composed of both positive (affiliative) and negative (agonistic) interactions represented opposing effects. Categorizing social interactions enables observational and other social research, such as Gemeinschaft and Gesellschaft (), collective conscio ...

Imitation
Imitation (from Latin ''imitatio'', "a copying, imitation") is a behavior whereby an individual observes and replicates another's behavior. Imitation is also a form of learning that leads to the "development of traditions, and ultimately our culture. It allows for the transfer of information (behaviors, customs, etc.) between individuals and down generations without the need for genetic inheritance." The word ''imitation'' can be applied in many contexts, ranging from animal training to politics. The term generally refers to conscious behavior; subconscious imitation is termed mirroring. Anthropology and social sciences In anthropology, some theories hold that all cultures imitate ideas from one of a few original cultures or several cultures whose influence overlaps geographically. Evolutionary diffusion theory holds that cultures influence one another, but that similar ideas can be developed in isolation. Scholars as well as popular authors have argued that the role of imitati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Utilization Behavior
Utilization behavior (UB) is a type of neurobehavioral phenomena that involves someone grabbing objects in view and starting the 'appropriate' behavior associated with it at an 'inappropriate' time.Ishihara, K., Nishino, H., Maki, T., Kawamura, M., & Murayama, S. (2012). Utilization behavior as a white matter disconnection syndrome. Cortex, 38(3), 379-387. Patients exhibiting utilization behavior have difficulty resisting the impulse to operate or manipulate objects which are in their visual field and within reach. Characteristics of UB include unintentional, unconscious actions triggered by the immediate environment. The unpreventable excessive behavior has been linked to lesions in the frontal lobe. UB has also been referred to as "bilateral magnetic apraxia" and "hypermetamorphosis".Eslinger, P. (2002). The Anatomic Basis Of Utilization: A Shift From Frontal-Parietal To Intra-Frontal Mechanisms. Division of Neurology, 1-4. Background Individuals who display utilization behavior ...

ADHD
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 diffic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Emotional Dysregulation
Emotional dysregulation is characterized by an inability to flexibly respond to and manage emotional states, resulting in intense and prolonged emotional reactions that deviate from social norms, given the nature of the environmental stimuli encountered. Such reactions not only deviate from accepted social norms but also surpass what is informally deemed appropriate or proportional to the encountered stimuli. It is often linked to physical factors such as brain injury, or psychological factors such as adverse childhood experiences, and ongoing maltreatment, including child abuse, neglect, or institutional abuse. Emotional dysregulation may be present in people with psychiatric and neurodevelopmental disorders such as attention deficit hyperactivity disorder, autism spectrum disorder, bipolar disorder, borderline personality disorder, complex post-traumatic stress disorder, and fetal alcohol spectrum disorders. The dysregulation of emotions is also present in individuals w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anxiety
Anxiety is an emotion characterised by an unpleasant state of inner wikt:turmoil, turmoil and includes feelings of dread over Anticipation, anticipated events. Anxiety is different from fear in that fear is defined as the emotional response to a present threat, whereas anxiety is the anticipation of a future one. It is often accompanied by nervous behavior such as pacing back and forth, Somatic anxiety, somatic complaints, and Rumination (psychology), rumination. Anxiety is a feeling of uneasiness and worry, usually generalized and unfocused as an overreaction to a situation that is only subjectively seen as menacing. It is often accompanied by muscular tension, restlessness, Fatigue (medical), fatigue, inability to catch one's breath, tightness in the abdominal region, nausea, and problems in concentration. Anxiety is closely related to fear, which is a response to a real or perceived immediate threat (fight-or-flight response); anxiety involves the expectation of a future t ...

Depression (mood)
Depression is a mental state of low Mood (psychology), mood and aversion to activity. It affects about 3.5% of the global population, or about 280 million people worldwide, as of 2020. Depression affects a person's thoughts, behavior, feelings, and subjective well-being, sense of well-being. The pleasure or joy that a person gets from certain experiences is reduced, and the afflicted person often experiences a loss of motivation or interest in those activities. People with depression may experience sadness, feelings of dejection or hopelessness, difficulty in thinking and concentration, or a significant change in appetite or time spent sleeping; Suicidal ideation, suicidal thoughts can also be experienced. Depression can have multiple, sometimes overlapping, origins. Depression can be a symptom of some mood disorders, some of which are also commonly called ''depression'', such as major depressive disorder, bipolar disorder and dysthymia. Additionally, depression can be a norm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
