Language delayA language delay is a language disorder in which a child fails to develop language abilities at the usual age-appropriate period in their developmental timetable. It is most commonly seen in children ages two to seven years-old and can continue into adulthood. The reported prevalence of language delay ranges from 2.3 to 19 percent. Language is a uniquely human form of communication that entails the use of words in a standard and structured way. Language is distinct from communication. Communication is a two-stage process.
EgocentrismEgocentrism is the inability to differentiate between self and other. More specifically, it is the inability to accurately assume or understand any perspective other than one's own. Egocentrism is found across the life span: in infancy, early childhood, adolescence, and adulthood. Although egocentric behaviors are less prominent in adulthood, the existence of some forms of egocentrism in adulthood indicates that overcoming egocentrism may be a lifelong development that never achieves completion.
HypotoniaHypotonia is a state of low muscle tone (the amount of tension or resistance to stretch in a muscle), often involving reduced muscle strength. Hypotonia is not a specific medical disorder, but a potential manifestation of many different diseases and disorders that affect motor nerve control by the brain or muscle strength. Hypotonia is a lack of resistance to passive movement, whereas muscle weakness results in impaired active movement.
PubertyPuberty is the process of physical changes through which a child's body matures into an adult body capable of sexual reproduction. It is initiated by hormonal signals from the brain to the gonads: the ovaries in a girl, the testes in a boy. In response to the signals, the gonads produce hormones that stimulate libido and the growth, function, and transformation of the brain, bones, muscle, blood, skin, hair, breasts, and sex organs. Physical growth—height and weight—accelerates in the first half of puberty and is completed when an adult body has been developed.
PreschoolA preschool, also known as nursery school, pre-primary school, play school or creche, is an educational establishment or learning space offering early childhood education to children before they begin compulsory education at primary school. It may be publicly or privately operated, and may be subsidized from public funds. Terminology varies by country. In some European countries the term "kindergarten" refers to formal education of children classified as ISCED level 0 – with one or several years of such education being compulsory – before children start primary school at ISCED level 1.
Child neglectA form of child abuse, child neglect is an act of caregivers (e.g., parents) 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.
Behavior analysis of child developmentThe behavioral analysis of child development originates from John B. Watson's behaviorism. In 1948, Sidney Bijou took a position as associate professor of psychology at the University of Washington and served as director of the university's Institute of Child Development. Under his leadership, the Institute added a child development clinic and nursery school classrooms where they conducted research that would later accumulate into the area that would be called "Behavior Analysis of Child Development".
Play (activity)Play is a range of intrinsically motivated activities done for recreational pleasure and enjoyment. Play is commonly associated with children and juvenile-level activities, but may be engaged in at any life stage, and among other higher-functioning animals as well, most notably mammals and birds. Many prominent researchers in the field of psychology, including Melanie Klein, Jean Piaget, William James, Sigmund Freud, Carl Jung and Lev Vygotsky have erroneously viewed play as confined to the human species, believing play was important for human development and using different research methods to prove their theories.
Speech repetitionSpeech repetition occurs when individuals speak the sounds that they have heard another person pronounce or say. In other words, it is the saying by one individual of the spoken vocalizations made by another individual. Speech repetition requires the person repeating the utterance to have the ability to map the sounds that they hear from the other person's oral pronunciation to similar places and manners of articulation in their own vocal tract.
Childhood obesityChildhood obesity is a condition where excess body fat negatively affects a child's health or well-being. As methods to determine body fat directly are difficult, the diagnosis of obesity is often based on BMI. Due to the rising prevalence of obesity in children and its many adverse health effects it is being recognized as a serious public health concern. The term 'overweight' rather than 'obese' is often used when discussing childhood obesity, as it is less stigmatizing, although the term 'overweight' can also refer to a different BMI category.
