Adolescence
A period of the life course between the time puberty begins and the time adult status is approached, when young people are in the process of preparing to take on the roles and responsibilities of adulthood in their culture.
Life-cycle Service
A period in their late teens and 20s in which young people from the 16th to 19th century engaged in domestic service, farm service, or apprenticeships in various trades and crafts
Child Study Movement
Late 19th century group, led by G. Stanley Hall, that advocated research on child and adolescent development and the improvement of conditions for children and adolescents in the family, school, and workplace.
Recapitulation
Now-discredited theory that held that the development of each individual recapitulates the evolutionary development of the human species as a whole.
Storm and Stress

Survey
A questionnaire study that involves asking a large number of people questions about their opinions, or behavior.
Stratified Sampling
Sampling technique in which researchers select participants so that various categories of people are represented in proportions equal to their presence in the population.
Random Sample
Sampling technique in which the people selected for participation in a study are chosen randomly, meaning that no one in the population has a better or worse chance of being selected than anyone else.
Menarche

Reliability
Characteristic of a measure that refers to the extent to which results of the measure on one occasion are similar to results of the measure on a separate occasion
Validity
The truthfulness of a measure, that is, the extent to which it measures what it claims to measure.
Experimental Research Method
A research method that entails assigning participants randomly to an experimental group that received a treatment and a control group that does not receive the treatment, then comparing the two groups in a posttest.

Monozygotic (MZ) Twins
Twins with exactly the same genotype. Also known as identical twins.
Dizygotic (DZ) Twins
Twins with about half their genotype in common, the same as for other siblings. Also known as fraternal twins.
Correlation Versus Causation
A correlation is a predictable relationship between two variables, such that knowing one of the variables makes it possible to predict the other. However, just because two variables are correlated does not mean that one causes the other.
Longitudinal Study
A study in which data is collected from the participants on more than one occasion.
Patriarchal Authority
Cultural beliefs in the absolute authority of the father over his wife and children
Filial Piety
Confucian belief, common in many Asian societies, that children are obligated to respect, obey, and revere their parents, especially the father.
Caste System
Hindu belief that people are born into particular caste based on their moral and spiritual conduct in their previous life. A person’s caste then determines their status in Indian society.
Globalization
Increasing worldwide technological and economic integration, which is making different parts of the world increasingly connected and increasingly similar culturally.
Bicultural
Having an identity that includes aspects of two different cultures.
Resilience
Overcoming adverse environmental circumstances to achieve healthy development.
Puberty
The changes in physiology, anatomy, and physical functioning that develop a person into a mature adult biologically and prepare the body for sexual reproduction.
Endocrine System
A network of glands in the body. Through hormones, the glands coordinate their functioning and affect the development and functioning of the body.
Hormones
Chemicals, released by the glands of the endocrine system, that affect the development and functioning of the body, including development during puberty.
Hypothalamus
The “master gland,” located in the lower part of the brain beneath the cortex, that affects a wide range of physiological and psychological functioning that stimulates and regulates the production of hormones by other glands, including the ones involved in the initiation of puberty.
Gonadotropin-releasing hormone (GnRH)
Hormone released by the hypothalamus that causes gonadotropins to be released by the pituitary
Leptin
A protein, produced by fat cells, that signals the hypothalamus to initiate the hormonal changes of puberty.
Pituitary Gland
A gland about half an inch long located at the base of the brain that releases gonadotropins as part of the body’s preparation for reproduction.
Gonadotropins
Hormones (FSH and LH) that stimulate the development of gametes.
Follicle-stimulating hormone (FSH)
Along with LH, stimulates the development of gametes and sex hormones in the ovaries and testicles.
Luteinizing Hormone (LH)
Along with FSH, stimulates the development of gametes and sex hormones in the ovaries and testicles
Gametes
Cells, distinctive to each sex, that are involved in reproduction (egg cells in the ovaries of the female and sperm in the testes of the male).
Gonads
The ovaries and testicles. Also known as the sex glands.
Sex Hormones
Androgens and estrogens that cause the development of primary and secondary sex characteristics.
Estrogens
The sex hormones that have especially high levels in females from puberty onward and are mostly responsible for female primary and secondary sex characteristics
Androgens
The sex hormones that have especially high levels in males from puberty onward and are mostly responsible for male primary and secondary sex characterstics.
Estradiol
The estrogen most important in pubertal development among girls.
Testosterone
The androgen most important in pubertal development among boys.
Adrenocorticotropic Hormone
The hormone that causes the adrenal glands to increase androgen production.
Feedback Loop
System of hormones involving the hypothalamus, the pituitary gland, and the gonads, which monitors and adjusts the levels of the sex hormones.
Set Point
Optimal level of sex hormones in the body. When this point is reached, responses in the glands of the feedback loop cause the production of sex hormones can be reduced.
Adolescent Growth Spurt
The rapid increase in height that takes place at the beginning of puberty.
Peak Height Velocity
The point at which the adolescent growth spurt is at its maximum rate
Asynchronicity
Uneven growth of different parts of the body during puberty
Extremities
The feet, hands, and head.
Vital Capacity
The amount of air that can be exhaled after a deep breath, which increases rapidly during puberty, especially for boys
Maximum Oxygen Uptake (VO2 max)
A measure of the ability of the body to take in oxygen and transport it to various organs; peaks in the early 20s.
Cardiac Output
A measure of the quantity of blood pumped by the heart.

Labia minora
Part of vulva; latin for “small lips”
Clitoris
Part of vulva in which females’ sexual sensations are concentrated
Breast Buds
The first slight enlargement of the breast in girls at puberty
Areola
Area surrounding the nipple on the breast; enlarges at puberty
Secular Trend
A change in the characteristics of a population over time
Reaction Range
Term meaning that genes establish a range of possible development and environment determines where development takes place within that range.
Incest Taboo
The prohibition on sexual relations between family members. Believed to be biologically based, as children born to closely related parents are at higher risk for genetic disorders.
Premenstrual Syndrome (PMS)
The combination of behavioral, emotional, and physical symptoms that occur in some females the week before menstruation
Semenarche
A male’s first ejaculation
Age-graded
Organized by age, for example in schools
Nature-Nurture Debate
Debate over the relative importance of biology and the environment in human development
Theory of Genotype–> Environment Effects
Theory that both genetics and environment make essential contributions to human development but are difficult to unravel because our genes actually influence the kind of environment we experience.
Passive Genotype–>Environmental effects
Situation in biological families that parents provide both genes and environment for their children, making genes and environment difficult to separate in their effects on children’s development.
