Developmental psychology is the scientific study of how and why humans grow, change, and adapt across the course of their lives. Originally concerned with infants and children, the field has expanded to include adolescence, adult development, aging, and the entire lifespan. Developmental psychologists aim to explain how thinking, feeling, and behaviors change throughout life. This field examines change across three major dimensions, which are physical development, cognitive development, and social emotional development. Within these three dimensions are a broad range of topics including motor skills, executive functions, moral understanding, language acquisition, social change, personality, emotional development, self-concept, and identity formation.
Human sexual activity, human sexual practice or human sexual behaviour is the manner in which humans experience and express their sexuality. People engage in a variety of sexual acts, ranging from activities done alone to acts with another person in varying patterns of frequency, for a wide variety of reasons. Sexual activity usually results in sexual arousal and physiological changes in the aroused person, some of which are pronounced while others are more subtle. Sexual activity may also include conduct and activities which are intended to arouse the sexual interest of another or enhance the sex life of another, such as strategies to find or attract partners, or personal interactions between individuals. Sexual activity may follow sexual arousal.
Orgasm or sexual climax is the sudden discharge of accumulated sexual excitement during the sexual response cycle, resulting in rhythmic, involuntary muscular contractions in the pelvic region characterized by sexual pleasure. Experienced by males and females, orgasms are controlled by the involuntary or autonomic nervous system. They are usually associated with involuntary actions, including muscular spasms in multiple areas of the body, a general euphoric sensation, and, frequently, body movements and vocalizations. The period after orgasm is typically a relaxing experience, attributed to the release of the neurohormones oxytocin and prolactin as well as endorphins.
Sexual intercourse is sexual activity involving the insertion and thrusting of the male penis inside the female vagina for sexual pleasure, reproduction, or both. This is also known as vaginal intercourse or vaginal sex. Sexual penetration has been known by humans since the dawn of time, and has been an instinctive form of sexual behaviour and psychology among humans. Other forms of penetrative sexual intercourse include anal sex, oral sex, fingering and penetration by use of a dildo, and vibrators. These activities involve physical intimacy between two or more people and are usually used among humans solely for physical or emotional pleasure. They can contribute to human bonding.
A child (pl. children) is a human being between the stages of birth and puberty, or between the developmental period of infancy and puberty. It may also refer to an unborn human being. The legal definition of child generally refers to a minor, otherwise known as a person younger than the age of majority. Children generally have fewer rights and responsibilities than adults. They are generally classed as unable to make serious decisions.
Sexual fetishism or erotic fetishism is a sexual fixation on a nonliving object or body part. The object of interest is called the fetish; the person who has a fetish for that object is a fetishist. A sexual fetish may be regarded as a non-pathological aid to sexual excitement, or as a mental disorder if it causes significant psychosocial distress for the person or has detrimental effects on important areas of their life. Sexual arousal from a particular body part can be further classified as partialism.
Preadolescence is a stage of human development following middle childhood and preceding adolescence. It commonly ends with the beginning of puberty. Preadolescence is commonly defined as ages 8–12 ending with the major onset of puberty. It may also be defined as simply the 2-year period before the major onset of puberty. Preadolescence can bring its own challenges and anxieties.
Sexual behaviors in children are common and may range from normal and developmentally appropriate to abusive. These behaviors may include self-stimulation, interest in sex, curiosity towards sex and the opposite gender, exhibitionism, voyeurism, gender role behaviors and engagement in interpersonal sexual acts.
The history of intersex surgery is intertwined with the development of the specialities of pediatric surgery, pediatric urology, and pediatric endocrinology, with our increasingly refined understanding of sexual differentiation, with the development of political advocacy groups united by a human qualified analysis, and in the last decade by doubts as to efficacy, and controversy over when and even whether some procedures should be performed.
In psychoanalysis, psychosexual development is a central element of the sexual drive theory. According to Freud, personality develops through a series of childhood stages in which pleasure seeking energies from the child become focused on certain erogenous areas. An erogenous zone is characterized as an area of the body that is particularly sensitive to stimulation. The five psychosexual stages are the oral, the anal, the phallic, the latent, and the genital. The erogenous zone associated with each stage serves as a source of pleasure. Being unsatisfied at any particular stage can result in fixation. On the other hand, being satisfied can result in a healthy personality. Sigmund Freud proposed that if the child experienced frustration at any of the psychosexual developmental stages, they would experience anxiety that would persist into adulthood as a neurosis, a functional mental disorder.
"Playing doctor" is a phrase used colloquially in the Western world to refer to children examining each other's genitals. It originates from children using the pretend roles of doctor and patient as a pretext for such an examination. However, whether or not such role-playing is involved, the phrase is used to refer to any similar examination.
Child abuse is physical, sexual, emotional and/or psychological maltreatment or neglect of a child, 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 wrongful harm to a child and can occur in a child's home, or in organizations, schools, or communities the child interacts with.
Child development involves the biological, psychological and emotional changes that occur in human beings between birth and the conclusion of adolescence.
Masturbation is a form of autoeroticism in which a person sexually stimulates their own genitals for sexual arousal or other sexual pleasure, usually to the point of orgasm. The stimulation may involve the use of hands, everyday objects, sex toys, or more rarely, the mouth. Masturbation may also be performed with a sex partner, either masturbating together or watching the other partner masturbate.
Human sexuality covers a broad range of topics, including the physiological, psychological, social, cultural, political, philosophical, ethical, moral, theological, legal and spiritual or religious aspects of sex and human sexual behavior.
Human sexuality is the way people experience and express themselves sexually. This involves biological, psychological, physical, erotic, emotional, social, or spiritual feelings and behaviors. Because it is a broad term, which has varied with historical contexts over time, it lacks a precise definition. The biological and physical aspects of sexuality largely concern the human reproductive functions, including the human sexual response cycle.
Gratification disorder is a rare and often misdiagnosed form of masturbatory behavior, or the behavior of stimulating of one's own genitals, seen predominantly in infants and toddlers. Most pediatricians agree that masturbation is both normal and common behavior in children at some point in their childhood. The behavior is labeled a disorder when the child forms a habit, and misdiagnoses of the behavior can lead to unnecessary and invasive testing for other severe health conditions, including multiple neurological or motor disorders.
The following outline is provided as an overview of and topical guide to human sexuality:
Animal non-reproductive sexual behavior encompasses sexual activities that non-human animals participate in which do not lead to the reproduction of the species. Although procreation continues to be the primary explanation for sexual behavior in animals, recent observations on animal behavior have given alternative reasons for the engagement in sexual activities by animals. Animals have been observed to engage in sex for social interaction bonding, exchange for significant materials, affection, mentorship pairings, sexual enjoyment, or as demonstration of social rank. Observed non-procreative sexual activities include non-copulatory mounting, oral sex, genital stimulation, anal stimulation, interspecies mating, and acts of affection, although it is doubted that they have done this since the beginning of their existence. There have also been observations of sex with cub participants, same-sex sexual interaction, as well as sex with dead animals.
Social emotional development represents a specific domain of child development. It is a gradual, integrative process through which children acquire the capacity to understand, experience, express, and manage emotions and to develop meaningful relationships with others. As such, social emotional development encompasses a large range of skills and constructs, including, but not limited to: self-awareness, joint attention, play, theory of mind, self-esteem, emotion regulation, friendships, and identity development.
