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. In most cases, children are the victims of physical abuse, but adults can also be victims, as in cases of domestic violence or workplace aggression. Alternative terms sometimes used include physical assault or physical violence, and may also include sexual abuse. Physical abuse may involve more than one abuser, and more than one victim.
Harry Frederick Harlow was an American psychologist best known for his maternal-separation, dependency needs, and social isolation experiments on rhesus monkeys, which manifested the importance of caregiving and companionship to social and cognitive development. He conducted most of his research at the University of Wisconsin–Madison, where humanistic psychologist Abraham Maslow worked with him for a short period of time.
The Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) is one of the National Institutes of Health (NIH) in the United States Department of Health and Human Services. It supports and conducts research aimed at improving the health of children, adults, families, and communities, including:
A form of child abuse, child neglect is an act of caregivers that results in depriving a child of their basic needs, such as the failure to provide adequate supervision, health care, clothing, or housing, as well as other physical, emotional, social, educational, and safety needs. All societies have established that there are necessary behaviours a caregiver must provide for a child to develop physically, socially, and emotionally. Causes of neglect may result from several parenting problems including mental disorders, unplanned pregnancy, substance use disorder, unemployment, over employment, domestic violence, and, in special cases, poverty.
Developmental disability is a diverse group of chronic conditions, comprising mental or physical impairments that arise before adulthood. Developmental disabilities cause individuals living with them many difficulties in certain areas of life, especially in "language, mobility, learning, self-help, and independent living". Developmental disabilities can be detected early on and persist throughout an individual's lifespan. Developmental disability that affects all areas of a child's development is sometimes referred to as global developmental delay.
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.
Human bonding is the process of development of a close, interpersonal relationship between two or more people. It most commonly takes place between family members or friends, but can also develop among groups, such as sporting teams and whenever people spend time together. Bonding is a mutual, interactive process, and is different from simple liking. It is the process of nurturing social connection.
In sociology and psychology, poisonous pedagogy, also called black pedagogy, is any traditional child-raising methods which modern pedagogy considers repressive and harmful. It includes behaviours and communication that theorists consider to be manipulative or violent, such as corporal punishment.
Sibling abuse includes the physical, psychological, or sexual abuse of one sibling by another. More often than not, the younger sibling is abused by the older sibling, however this is not always the case. Sibling abuse is the most common of family violence in the US, but the least reported. As opposed to sibling rivalry, sibling abuse is characterized by the one-sided treatment of one sibling to another.
Stephen J. Suomi is chief of the Laboratory of Comparative Ethology at the National Institute of Child Health and Human Development (NICHD) in Bethesda, Maryland. He is also a research professor at the University of Virginia, the University of Maryland, and Johns Hopkins University. He is involved with the Experience-based Brain & Biological Development Program, launched in 2003 by the Canadian Institute for Advanced Research.
Childhood trauma is often described as serious adverse childhood experiences (ACEs). Children may go through a range of experiences that classify as psychological trauma; these might include neglect, abandonment, sexual abuse, emotional abuse, and physical abuse, witnessing abuse of a sibling or parent, or having a mentally ill parent. These events have profound psychological, physiological, and sociological impacts and can have negative, lasting effects on health and well-being such as unsocial behaviors, attention deficit hyperactivity disorder (ADHD), and sleep disturbances. Similarly, children with mothers who have experienced traumatic or stressful events during pregnancy can increase the child's risk of mental health disorders and other neurodevelopmental disorders. Kaiser Permanente and the Centers for Disease Control and Prevention's 1998 study on adverse childhood experiences determined that traumatic experiences during childhood are a root cause of many social, emotional, and cognitive impairments that lead to increased risk of unhealthy self-destructive behaviors, risk of violence or re-victimization, chronic health conditions, low life potential and premature mortality. As the number of adverse experiences increases, the risk of problems from childhood through adulthood also rises. Nearly 30 years of study following the initial study has confirmed this. Many states, health providers, and other groups now routinely screen parents and children for ACEs.
Maternal deprivation is a scientific term summarising the early work of psychiatrist and psychoanalyst John Bowlby on the effects of separating infants and young children from their mother. Although the effect of loss of the mother on the developing child had been considered earlier by Freud and other theorists, Bowlby's work on delinquent and affectionless children and the effects of hospital and institutional care led to his being commissioned to write the World Health Organization's report on the mental health of homeless children in post-war Europe whilst he was head of the Department for Children and Parents at the Tavistock Clinic in London after World War II. The result was the monograph Maternal Care and Mental Health published in 1951, which sets out the maternal deprivation hypothesis.
The differential susceptibility theory proposed by Jay Belsky is another interpretation of psychological findings that are usually discussed according to the diathesis-stress model. Both models suggest that people's development and emotional affect are differentially affected by experiences or qualities of the environment. Where the Diathesis-stress model suggests a group that is sensitive to negative environments only, the differential susceptibility hypothesis suggests a group that is sensitive to both negative and positive environments. A third model, the vantage-sensitivity model, suggests a group that is sensitive to positive environments only. All three models may be considered complementary, and have been combined into a general environmental sensitivity framework.
In the context of caregiving, neglect is a form of abuse where the perpetrator, who is responsible for caring for someone who is unable to care for themselves, fails to do so. It can be a result of carelessness, indifference, or unwillingness and abuse.
Trauma bonds is a term developed by Patrick Carnes to describe emotional bonds with an individual that arise from a recurring, cyclical pattern of abuse perpetuated by intermittent reinforcement through rewards and punishments. The process of forming trauma bonds is referred to as trauma bonding or traumatic bonding. A trauma bond usually involves a victim and a perpetrator in a uni-directional relationship wherein the victim forms an emotional bond with the perpetrator. This can also be conceptualized as a dominated-dominator or an abused-abuser dynamic. Two main factors are involved in the establishment of a trauma bond: a power imbalance and intermittent reinforcement of good and bad treatment, or reward and punishment. Trauma bonding can occur in the realms of romantic relationships, platonic friendships, parent-child relationships, incestuous relationships, cults, hostage situations, manager vs their direct reports, sex trafficking, or tours of duty among military personnel.
The effects of domestic violence on children have a tremendous impact on the well-being and developmental growth of children witnessing it. Children who witness domestic violence in the home often believe that they are to blame, live in a constant state of fear, and are 15 times more likely to be victims of child abuse. Close observation during an interaction can alert providers to the need for further investigation and intervention, such as dysfunctions in the physical, behavioral, emotional, and social areas of life, and can aid in early intervention and assistance for child victims.
Developmental homeostasis is a process in which animals develop more or less normally, despite defective genes and deficient environments. It is an organisms ability to overcome certain circumstances in order to develop normally. This can be either a physical or mental circumstance that interferes with either a physical or mental trait. Many species have a specific norm, where those who fit that norm prosper while those who don't are killed or find it difficult to thrive. It is important that the animal be able to interact with the other group members effectively. Animals must learn their species' norms early to live a normal, successful life for that species.
