Adolescence: what do transmission, transition and translation have to do with it?

Open access

Abstract

Negotiating the transition from dependence on parents to relative independence is not a unique demand for today's youth but has a long evolutionary history (transmission) and is shared across mammalian species (translation). However, behavioral changes observed during this period are often described as delinquent. This review examines changes in explorative and emotive behaviors during the transition into and out of adolescence and the underlying neurobiological bases in the context of adaptive and maladaptive functions.

TL;DR

This review argues that adolescence is an evolutionarily conserved transition from parental dependence to independence, not simply a period of delinquency. It proposes that heightened limbic responses to motivational and emotional cues, combined with still-maturing prefrontal control, explain both adaptive exploration and increased vulnerability.

Key findings

  • Human adolescent mortality rises by 200% despite better physical and reasoning abilities than children, largely from preventable causes such as accidents, suicide, and homicide.
  • Reward sensitivity and sensation-seeking follow a curvilinear pattern, peaking around ages 13–17 or 10–15 depending on the measure, while impulsivity declines linearly with age; in one study of over 900 individuals aged 10–30, sensation-seeking peaked between 10 and 15 and impulsivity decreased with age.
  • Adolescents show exaggerated ventral striatal responses to reward cues in several imaging studies, but some studies report diminished striatal activity, and amygdala responses to threat are initially elevated in adolescents relative to children and adults.
  • Animal and human work suggests pubertal hormones and chronological age separately influence brain and behavior, with dopamine-rich frontostriatal circuits undergoing marked changes during adolescence.

Methods

  • Narrative review synthesizing human behavioral, human neuroimaging, and comparative animal studies rather than presenting new primary data.
  • Organizes evidence around Tinbergen-style questions: causes/control of adolescent behavior, developmental change, and adaptive function.
  • Proposes a conceptual model in which hormonally sensitive limbic systems mature earlier than age-dependent prefrontal control systems, producing a temporary imbalance.

Limitations

  • The paper states that disentangling age and pubertal effects is difficult because the two are strongly associated and puberty timing varies widely.
  • It notes mixed imaging findings on ventral striatal activity in adolescents and unresolved controversy over whether dopamine systems are hypoactive or hypersensitive.
  • It states that equating the appetitive quality of rewards across ages and species requires more investigation; the text also makes evident that this is a narrative review with many cited works still in press or in review, and the central model is conceptual rather than directly tested.

    Findings from nonhuman animal models of adolescence can be translated to humans.

    Laboratory tasks used in the cited studies validly index the cognitive, motivational, and emotional constructs they are said to measure.

    “Using an anti-saccade task with a promise of financial reward for accurate performance on some trials but not others, they showed that promise of a reward facilitated adolescent performance more than adults.”
  • The paper relies on this without support.

    Measures of puberty such as Tanner staging and hormonal assays validly capture pubertal maturation.

    “Sexual maturation is typically assessed by physical exam or Tanner staging by the individual or parent, but more and more hormonal measures are being assessed, which present challenges given the large fluctuations in early stages of puberty and during the menstrual cycle, yet, move the field forward beyond the use of age as a proxy for pubertal maturation.”
  • The paper relies on this without support.

    During adolescence, amygdala response is heightened relative to children and adults.

    “During adolescence, when the amygdala response is heightened relative to that observed in children and adults (imbalance), more top down control is needed.”

    The brain differs in sensitivity to testosterone levels across development.

    “Consistent with this view, is how the brain differs in sensitivity to testosterone levels across development.”

    The transition from parental dependence to relative independence has a long evolutionary history and is shared across mammalian species.

    “Negotiating the transition from dependence on parents to relative independence is not a unique demand for today’s youth, but has a long evolutionary history and is shared across mammalian species.”

    In western civilization, the transition period has been prolonged for humans because parental independence is increasingly postponed in many individuals.

    “This period of transition has been prolonged in western civilization for humans with the increasingly occurring postponement of parental independence in many individuals.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-10-04, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-04 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Cited sources are checked with a language model’s help (gpt-6-sol).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
