Speech sound disorderA speech sound disorder (SSD) is a speech disorder in which some sounds (phonemes) are not produced or used correctly. The term "protracted phonological development" is sometimes preferred when describing children's speech, to emphasize the continuing development while acknowledging the delay. Speech sound disorders may be subdivided into two primary types, articulation disorders (also called phonetic disorders) and phonemic disorders (also called phonological disorders).
Philosophical skepticismPhilosophical skepticism (UK spelling: scepticism; from Greek σκέψις skepsis, "inquiry") is a family of philosophical views that question the possibility of knowledge. It differs from other forms of skepticism in that it even rejects very plausible knowledge claims that belong to basic common sense. Philosophical skeptics are often classified into two general categories: Those who deny all possibility of knowledge, and those who advocate for the suspension of judgment due to the inadequacy of evidence.
Neurodevelopmental disorderNeurodevelopmental disorders are a group of neurological disorders that affect the development of the nervous system, leading to abnormal brain function which may affect emotion, learning ability, self-control, and memory. The effects of neurodevelopmental disorders tend to last for a person's lifetime. Neurodevelopmental disorders are impairments of the growth and development of the brain and/or central nervous system.
Pervasive developmental disorderThe diagnostic category pervasive developmental disorders (PDD), as opposed to specific developmental disorders (SDD), was a group of disorders characterized by delays in the development of multiple basic functions including socialization and communication. It was defined by the Diagnostic and Statistical Manual of Mental Disorders (DSM) (from 1980 to 2013), and the International Classification of Diseases (ICD) (until 2022).
Communication disorderA communication disorder is any disorder that affects an individual's ability to comprehend, detect, or apply language and speech to engage in dialogue effectively with others. The delays and disorders can range from simple sound substitution to the inability to understand or use one's native language. Disorders and tendencies included and excluded under the category of communication disorders may vary by source. For example, the definitions offered by the American Speech–Language–Hearing Association differ from those of the Diagnostic Statistical Manual 4th edition (DSM-IV).
Body dysmorphic disorderBody dysmorphic disorder (BDD), occasionally still called dysmorphophobia, is a mental disorder characterized by the obsessive idea that some aspect of one's own body part or appearance is severely flawed and therefore warrants exceptional measures to hide or fix it. In BDD's delusional variant, the flaw is imagined. If the flaw is actual, its importance is severely exaggerated. Whether the physical imperfection is real or not, thoughts about it are pervasive and intrusive and may occupy the mind of the sufferer for many hours every day, causing severe distress and impairing otherwise normal activities.
Outline of selfThe following outline is provided as an overview of and topical guide to the human self: Self – individuality, from one's own perspective. To each person, self is that person. Oneself can be a subject of philosophy, psychology and developmental psychology; religion and spirituality, social science and neuroscience. Human Human condition Individuality (selfhood) – state or quality of being an individual; particularly of being a person separate from other persons and possessing his or her own needs or goals, rights and responsibilities.
Self-disorderA self-disorder, also called ipseity disturbance, is a psychological phenomenon of disruption or diminishing of a person's minimal self – the fundamental sense that one's experiences are truly one's own. People with self-disorder feel that their internal experiences are actually external; for example, they may experience their own thoughts as coming from outside themselves, whether in the form of true auditory hallucinations or merely as a vague sense that their thoughts do not belong to them.
True self and false selfThe true self (also known as real self, authentic self, original self and vulnerable self) and the false self (also known as fake self, idealized self, superficial self and pseudo self) are a psychological dualism conceptualized by English psychoanalyst Donald Winnicott. Winnicott used "true self" to denote a sense of self based on spontaneous authentic experience and a feeling of being alive, having a real self with little to no contradiction.
Self-perception theorySelf-perception theory (SPT) is an account of attitude formation developed by psychologist Daryl Bem. It asserts that people develop their attitudes (when there is no previous attitude due to a lack of experience, etc.—and the emotional response is ambiguous) by observing their own behavior and concluding what attitudes must have caused it. The theory is counterintuitive in nature, as the conventional wisdom is that attitudes determine behaviors. Furthermore, the theory suggests that people induce attitudes without accessing internal cognition and mood states.
