Professor Trevor Cox of the University of Salfords Acoustic Research Centre said, "We are pre-programmed to be repulsed by horrible things such as vomiting, as it is fundamental to staying alive to avoid nasty stuff." It is thought that disgust is triggered by the sound of vomiting to protect those nearby from possibly diseased food. Psychology

Cyclical Vomiting Syndrome
"Emetics" . The American Cyclopædia. 1879.
The 2010 Child Maltreatment Report (NCANDS), a yearly United States federal government report based on data supplied by state Child Protective Services (CPS) Agencies in the U.S., found that neglect/neglectful behavior was the "most common form of child maltreatment ".Neglectful acts can be divided into six sub-categories:
Supervisory neglect: characterized by the absence of a parent or guardian which can lead to physical harm, sexual abuse, or criminal behavior;
Physical neglect: characterized by the failure to provide the basic physical necessities, such as a safe and clean home;
Medical neglect: characterized by the lack of providing medical care;
Emotional neglect: characterized by a lack of nurturance, encouragement, and support;
Educational neglect: characterized by the caregivers lack to provide an education and additional resources to actively participate in the school system; and
Abandonment: when the parent or guardian leaves a child alone for a long period of time without a babysitter or caretaker.Neglected children may experience delays in physical and psychosocial development, possibly resulting in psychopathology and impaired neuropsychological functions including executive function, attention, processing speed, language, memory and social skills. Researchers investigating maltreated children have repeatedly found that neglected children in the foster and adoptive populations manifest different emotional and behavioral reactions to regain lost or secure relationships and are frequently reported to have disorganized attachments and a need to control their environment. Such children are not likely to view caregivers as being a source of safety, and instead typically show an increase in aggressive and hyperactive behaviors which may disrupt healthy or secure attachment with their adopted parents.
