PerceptionPerception () is the organization, identification, and interpretation of sensory information in order to represent and understand the presented information or environment. All perception involves signals that go through the nervous system, which in turn result from physical or chemical stimulation of the sensory system. Vision involves light striking the retina of the eye; smell is mediated by odor molecules; and hearing involves pressure waves.
Cognitive distortionA cognitive distortion is an exaggerated or irrational thought pattern involved in the onset or perpetuation of psychopathological states, such as depression and anxiety. Cognitive distortions are thoughts that cause individuals to perceive reality inaccurately. According to Aaron Beck's cognitive model, a negative outlook on reality, sometimes called negative schemas (or schemata), is a factor in symptoms of emotional dysfunction and poorer subjective well-being. Specifically, negative thinking patterns reinforce negative emotions and thoughts.
Disruptive mood dysregulation disorderDisruptive mood dysregulation disorder (DMDD) is a mental disorder in children and adolescents characterized by a persistently irritable or angry mood and frequent temper outbursts that are disproportionate to the situation and significantly more severe than the typical reaction of same-aged peers. DMDD was added to the DSM-5 as a type of depressive disorder diagnosis for youths. The symptoms of DMDD resemble those of attention deficit hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), anxiety disorders, and childhood bipolar disorder .
Suicide preventionSuicide prevention is a collection of efforts to reduce the risk of suicide. Suicide is often preventable, and the efforts to prevent it may occur at the individual, relationship, community, and society level. Suicide is a serious public health problem that can have long-lasting effects on individuals, families, and communities. Preventing suicide requires strategies at all levels of society. This includes prevention and protective strategies for individuals, families, and communities.
Self-neglectSelf-neglect is a behavioral condition in which an individual neglects to attend to their basic needs, such as personal hygiene, appropriate clothing, feeding, or tending appropriately to any medical conditions they have. More generally, any lack of self-care in terms of personal health, hygiene and living conditions can be referred to as self-neglect. Extreme self-neglect can be known as Diogenes syndrome. There are two types of self-neglect: intentional (active), and non-intentional (passive).
Dementia caregivingAs populations age, caring for people with dementia has become more common. Elderly caregiving may consist of formal care and informal care. Formal care involves the services of community and medical partners, while informal care involves the support of family, friends, and local communities. In most mild-to-medium cases of dementia, the caregiver is a spouse or an adult child. Over the period of time, more professional care in the form of nursing and other supportive care may be required medically, whether at home or in a long-term care facility.
Dementia praecoxDementia praecox (meaning a "premature dementia" or "precocious madness") is a disused psychiatric diagnosis that originally designated a chronic, deteriorating psychotic disorder characterized by rapid cognitive disintegration, usually beginning in the late teens or early adulthood. Over the years, the term dementia praecox was gradually replaced by the term schizophrenia, which initially had a meaning that included what is today considered the autism spectrum. The term dementia praecox was first used by German psychiatrist Heinrich Schüle in 1880.
Piaget's theory of cognitive developmentPiaget's theory of cognitive development is a comprehensive theory about the nature and development of human intelligence. It was originated by the Swiss developmental psychologist Jean Piaget (1896–1980). The theory deals with the nature of knowledge itself and how humans gradually come to acquire, construct, and use it. Piaget's theory is mainly known as a developmental stage theory. In 1919, while working at the Alfred Binet Laboratory School in Paris, Piaget "was intrigued by the fact that children of different ages made different kinds of mistakes while solving problems".
The Bell CurveThe Bell Curve: Intelligence and Class Structure in American Life is a 1994 book by psychologist Richard J. Herrnstein and political scientist Charles Murray, in which the authors argue that human intelligence is substantially influenced by both inherited and environmental factors and that it is a better predictor of many personal outcomes, including financial income, job performance, birth out of wedlock, and involvement in crime than are an individual's parental socioeconomic status.
