Child abuse is physical, sexual, and/or psychological maltreatment or neglect of a child or children, especially by a parent or a caregiver. Child abuse may include any act or failure to act by a parent or a caregiver that results in actual or potential harm to a child and can occur in a child's home, or in the organizations, schools, or communities the child interacts with.

Physical abuse is any intentional act causing injury, trauma, bodily harm or other physical suffering to another person or animal by way of bodily contact. Physical abuse is a type of abuse that involves physical violence, such as hitting, kicking, pushing, biting, choking, throwing objects, and using weapons. Physical abuse also includes using restraints or confinement, such as tying someone up, locking them in a room, or restraining them with drugs or alcohol. Physical abuse can also include withholding basic needs, such as food, clothing, or medical care. In addition to the physical injuries caused by physical abuse, it can also lead to psychological trauma, such as fear, anxiety, depression, and post-traumatic stress disorder. Physical abuse can occur in any relationship, including those between family members, partners, and caregivers. It can also occur in institutional settings, such as nursing homes, schools, and prisons. Physical abuse can have long-term physical, psychological, and social consequences, and can even be fatal.

An orphan is a child whose parents have died.

Verdingkinder, "contract children", or "indentured child laborers" were children in Switzerland who were taken from their parents, often due to poverty or moral reasons, and sent to live with new families, often poor farmers who needed cheap labour. In the early 2000s, many of these children, by then adults, publicly stated that they had been severely mistreated by their new families, suffering neglect, beatings and other physical and psychological abuse. The Verdingkinder scheme was common in Switzerland until the 1960s.

Psychiatric hospitals, also known as mental health hospitals, behavioral health hospitals, are hospitals or wards specializing in the treatment of severe mental disorders, such as schizophrenia, bipolar disorder, eating disorders, dissociative identity disorder, major depressive disorder and many others. Psychiatric hospitals vary widely in their size and grading. Some hospitals may specialize only in short-term or outpatient therapy for low-risk patients. Others may specialize in the temporary or permanent containment of patients who need routine assistance, treatment, or a specialized and controlled environment due to a psychiatric disorder. Patients often choose voluntary commitment, but those whom psychiatrists believe to pose significant danger to themselves or others may be subject to involuntary commitment and involuntary treatment. Psychiatric hospitals may also be called psychiatric wards/units when they are a subunit of a regular hospital.

Psychosis is a condition of the mind that results in difficulties determining what is real and what is not real. Symptoms may include delusions and hallucinations, among other features. Additional symptoms are incoherent speech and behavior that is inappropriate for a given situation. There may also be sleep problems, social withdrawal, lack of motivation, and difficulties carrying out daily activities. Psychosis can have serious adverse outcomes.

A hallucination is a perception in the absence of an external stimulus that has the qualities of a real perception. Hallucinations are vivid, substantial, and are perceived to be located in external objective space. Hallucination is a combination of 2 conscious states of brain wakefulness and REM sleep. They are distinguishable from several related phenomena, such as dreaming, which does not involve wakefulness; pseudohallucination, which does not mimic real perception, and is accurately perceived as unreal; illusion, which involves distorted or misinterpreted real perception; and mental imagery, which does not mimic real perception, and is under voluntary control. Hallucinations also differ from "delusional perceptions", in which a correctly sensed and interpreted stimulus is given some additional significance. Many hallucinations happen also during sleep paralyses.

Iconoclasm is the social belief in the importance of the destruction of icons and other images or monuments, most frequently for religious or political reasons. People who engage in or support iconoclasm are called iconoclasts, a term that has come to be figuratively applied to any individual who challenges "cherished beliefs or venerated institutions on the grounds that they are erroneous or pernicious."

Outsider art is art made by self-taught or supposedly naïve artists with typically little or no contact with the conventions of the art worlds. In many cases, their work is discovered only after their deaths. Often, outsider art illustrates extreme mental states, unconventional ideas, or elaborate fantasy worlds.

Jean Philippe Arthur Dubuffet was a French painter and sculptor. His idealistic approach to aesthetics embraced so-called "low art" and eschewed traditional standards of beauty in favor of what he believed to be a more authentic and humanistic approach to image-making. He is perhaps best known for founding the art movement art brut, and for the collection of works—Collection de l'art brut—that this movement spawned. Dubuffet enjoyed a prolific art career, both in France and in America, and was featured in many exhibitions throughout his lifetime.

Christmas is an annual festival commemorating the birth of Jesus Christ, observed primarily on December 25 as a religious and cultural celebration among billions of people around the world. A feast central to the Christian liturgical year, it is preceded by the season of Advent or the Nativity Fast and initiates the season of Christmastide, which historically in the West lasts twelve days and culminates on Twelfth Night. Christmas Day is a public holiday in many countries, is celebrated religiously by a majority of Christians, as well as culturally by many non-Christians, and forms an integral part of the holiday season organized around it.

In visual art, horror vacui, or kenophobia, is a phenomenon in which the entire surface of a space or an artwork is filled with detail and content, leaving as little perceived emptiness as possible. It relates to the antiquated physical idea, horror vacui, proposed by Aristotle who held that "nature abhors an empty space".

Music notation or musical notation is any system used to visually represent aurally perceived music played with instruments or sung by the human voice through the use of written, printed, or otherwise-produced symbols, including notation for durations of absence of sound such as rests.
