Preadolescence

Preadolescence, also commonly known as pre-teen, is a stage of human development following early childhood and preceding adolescence.^[1] It commonly ends with the beginning of puberty^[2] but may also be defined as ending with the start of the teenage years.^[3] For example, the age range is commonly designated as 10–13 years.^[4] Preadolescence can bring its own challenges and anxieties.

Terminology

Other slang and terminology used to refer to the preadolescent stage include tween, as a combination of the words "teen" and "between." ^[5][6] While known as preadolescent in psychology, the terms preteen, preteenager, or tween are common in everyday use. A preteen or preteenager^[1] is a person 12 and under.^[7] Generally, the term is restricted to those close to reaching age 12,^[1] especially age 11.^[8] Tween is an American neologism and marketing term^[9] for preteen, which is a blend of between and teen.^[7][8] People within this age range are variously described as tweens, preadolescents, tweenies, preteens, pubescents, junior highschoolers, middle schoolers,^[10] or tweenagers.^[11][12]

Prepubescence, puberty, and age range

Being prepubescent is not the same thing as being preadolescent. Instead, prepubescent (and sometimes child) is a term for boys and girls who have not developed secondary sex characteristics,^[13] while preadolescent is generally defined as those ranging from age 10 to 13 years.^[4][14] Preadolescence may also be defined as the period from 9 to 14 years.^[15][16]

The point at which a child becomes an adolescent is defined by the onset of puberty or the beginning of the teenage stage.^[2][3][13] However, in some individuals (particularly females), puberty begins in the preadolescence years.^[17][18] Studies indicate that the onset of puberty has been one year earlier with each generation since the 1950s.^[19]

One can also distinguish middle childhood and preadolescence^[15] – middle childhood from approximately 5–8 years, as opposed to the time children are generally considered to reach preadolescence.^[16] There is no exact agreement as to when preadolescence starts and ends.

Hormonal development and the development of sex characteristics

Early puberty begins as the result of the initiation of the pulsatile gonadotropin-releasing hormone (GnRH) secretion by the hypothalamus; the exact mechanism of this initiation is currently unknown and remains under investigation.^[20] Pulsatile GnRH secretion results in the pulsatile secretions of gonadotropins Luteinizing Hormone (LH) and Follicle Stimulating Hormone (FSH), which act on the gonads (ovaries or testicles) to cause increase secretion of sex steroids. In individuals with ovaries, the predominant sex steroid released is estrogen and in individuals with testicles, the predominant sex steroid released is testosterone. These sex hormones then lead to the development of secondary sex characteristics.^[21]

The stages of puberty can be described with the Tanner scale, also known as the Sexual Maturity Rating, which incorporates measurements and characteristics of primary and secondary sex characteristics, for example genital and breast development, as well as pubic hair growth. Pubertal development is regulated by the hypothalamic-pituitary-gonadal (HPG) axis.^[22] Tanner staging ranges from 1 through 5 (with 5 being the most developed).^[23] With regards to pubic hair development, the scale goes as follows: Stage 1-no hair; 2-downy hair; 3-scant terminal hair; 4-terminal hair overlying the pubic triangle; 5-terminal hair extending to the thigh. With regards to male genitalia development, the scale goes as follows: 1-testes at the same size and proportion of early childhood; 2-enlargement of the scrotum/change in texture of scrotal skin; 3-growth of the penis length-wise; 4-growth of the penis in terms of length and circumference; 5-adult-sized genitalia. With regards to female breast development, the scale is as follows: 1-no palpable gland tissue; 2-palpable breast bud under areola; 3-breast tissue palpable outside of areola; 4-areola elevated above breast contour; 5-areolar mound recedes into single breast contour. The average age in which both males and females reach Tanner stage 5 of pubertal development is around 15-16.^[24]

Neurological development

There are significant neurological changes that are expressed during preadolescence. White matter refers to the region of the nervous system corresponding to neuronal axons, which form fibers that convey information across different regions of the brain. In contrast, grey matter refers to the region of the nervous system corresponding to neuronal cell bodies, which process and relay neuronal signals. White matter volume increases at a relatively linear rate from ages 4 through 22, at a rate of about 12%, specifically focused in the frontal, parietal, and occipital lobes.^[25] Increases in white matter volume may be correlated to improvements of fine motor performance, auditory processing, as well as sensory information transfer between language areas of the brain. In contrast, cortical gray matter increases in early life, peaks in preadolescence, and declines through adulthood, with the exception of occipital lobe gray matter. For example, parietal lobe gray matter peaks at age 10 in girls and 12 in boys, while frontal lobe gray matter peaks at age 11 in girls and 12 in boys. Such changes might reflect overproduction of synapses in the preadolescent years; in subsequent years, there seems to be pruning dependent on environmental context, corresponding to increased synchronicity of neuron firing. A key caveat from these imaging studies, however, is that there exists significant variability in the timing and characteristics of neurological change in preadolescents. Neurological changes, particularly in the prefrontal cortex, appear to be highly dependent on environmental input.^[26] Toxins, hormones, and lifestyle factors including stress and nutrition impact neurological maturation, demonstrating the importance of early lifestyle health interventions in preadolescence with regards to neurological and psychological development.  

Psychological and development

Of the 'two major socializing agents in children's lives: the family environment...and formal educational institutions,'^[27] it is 'the family in its function a primary socializer of the child'^[28] that predominates in the first five years of life: middle childhood by contrast is characterized by 'a child's readiness for school...being self-assured and interested; knowing what kind of behavior is expected...being able to wait, to follow directions, and getting along with other children.'^[29]

Preadolescent children have a different view of the world from younger children in many significant ways. Typically, theirs is a more realistic view of life than the intense, fantasy-oriented world of earliest childhood. Preadolescents have more mature, sensible, realistic thoughts and actions: 'the most "sensible" stage of development...the child is a much less emotional being now.'^[30] They will often have developed a sense of ' intentionality. The wish and capacity to have an impact, and to act upon that with persistence';^[31] and will have a more developed sense of looking into the future and seeing effects of their actions (as opposed to early childhood where children often do not worry about their future). This can include more realistic job expectations ("I want to be an engineer when I grow up", as opposed to "I want to be a wizard"). Middle children generally show more investment 'in control over external reality through the acquisition of knowledge and competence':^[32] where they do have worries, these may be more a fear of kidnappings, rapes, and scary media events, as opposed to fantasy things (e.g., witches, monsters, ghosts).

Preadolescents may well view human relationships differently (e.g. they may notice the flawed, human side of authority figures). Alongside that, they may begin to develop a sense of self-identity, and to have increased feelings of independence: 'may feel an individual, no longer "just one of the family."'^[33] A different view on morality can emerge; and the middle child will also show more cooperativeness. The ability to balance one's own needs with those of others in group activities'.^[34] Many preadolescents will often start to question their home life and surroundings around this time and they may also start to form opinions that may differ from their upbringing in regards to issues such as politics, religion, sexuality, and gender roles.

Greater responsibility within the family can also appear, as middle children become responsible for younger siblings and relatives, as with babysitting; while preadolescents may start caring about what they look like and what they are wearing.

Middle children often begin to experience infatuation, limerence, puppy love, or love itself, though arguably at least with 'girls carrying out all the romantic interest....preadolescent girls' romantic pursuits often seem to be more aggressive than affectionate.'^[35]

Preadolescents may still suffer tantrums at the age of 13, sometimes leading to rash decisions regarding risky actions.^{[citation needed]}

Home from home

Where development has been optimal, preadolescents 'come to school for something to be added to their lives; they want to learn lessons...which can lead to their eventually working in a job like their parents.'^[36] When earlier developmental stages have gone astray, however, then, on the principle that 'if you miss a stage, you can always go through it later,'^[37] some middle children 'come to school for another purpose...[not] to learn but to find a home from home...a stable emotional situation in which they can exercise their own emotional liability, a group of which they can gradually become a part.'^[38]

Divorce

Children at the threshold of adolescence in the nine-to-twelve-year-old group^[39] would seem to have particular vulnerabilities to parental separation. Among such problems were the very "eagerness of these youngsters to be co-opted into the parental battling; their willingness to take sides...and the intense, compassionate, caretaking relations which led these youngsters to attempt to rescue a distressed parent often to their own detriment".^[40]

Media

Preadolescents may well be more exposed to popular culture than younger children and have interests based on internet trends, television shows and movies (no longer just cartoons), fashion, technology, music and social media. Preadolescents generally prefer certain brands, and are a heavily targeted market of many advertisers. Their tendency to buy brand-name items may be due to a desire to fit in, although the desire is not as strong as it is with teenagers.

Some scholars suggest that 'pre-adolescents ... reported frequent encounters with sexual material in the media, valued the information received from it, and used it as a learning resource ... and evaluated such content through what they perceived to be sexual morality.'^[41] However, other research has suggested that sexual media influences on preadolescent and adolescent sexual behavior is minimal.^[42]

Freud

Freud called this stage the latency period to indicate that sexual feelings and interest went underground.^[43] Erik H. Erikson noted that latency period children in middle childhood can then direct more of their energy into asexual pursuits such as school, athletics, and same-sex friendships.^[44] Nevertheless, recent research contradicts these notions—suggesting that sexual development, interest, and behavior among latent period children does not cease. Instead, the apparent lack of sexual interest is due to children not sharing their sexual interests/emotions with adults.^[45]
