Abstract

Adolescence is an evolutionarily conserved developmental phase characterized by hormonal, physiological, neural and behavioral alterations evident widely across mammalian species. For instance, adolescent rats, like their human counterparts, exhibit elevations in peer-directed social interactions, risk-taking/novelty seeking and drug and alcohol use relative to adults, along with notable changes in motivational and reward-related brain regions. After reviewing these topics, the present paper discusses conditioned preference and aversion data showing adolescents to be more sensitive than adults to positive rewarding properties of various drugs and natural stimuli, while less sensitive to the aversive properties of these stimuli. Additional experiments designed to parse specific components of reward-related processing using natural rewards have yielded more mixed findings, with reports of accentuated positive hedonic sensitivity during adolescence contrasting with studies showing less positive hedonic affect and reduced incentive salience at this age. Implications of these findings for adolescent substance abuse will be discussed.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Reward circuitry includes the dopamine neurotransmitter system and its projections to reward-relevant subcortical regions such as the ventral striatum.

    “This reward circuitry includes the DA neurotransmitter system and its projections to reward-relevant subcortical regions such as the ventral striatum (38).”

    From Adolescent Neurodevelopment (2013) · cites this paper as [38]

  • Adolescent rats are often more sensitive than adults to the rewarding properties of stimuli ranging from desirable tastes, social peers, and novelty to drugs of abuse including cocaine, amphetamine, nicotine, and alcohol.

    “Data supporting a strong biological component to this enhanced reward responsivity have been obtained using simple animal models, with adolescent rats likewise often more sensitive than adults to the rewarding properties of stimuli that range from desirable tastes, social peers, and novelty, to drugs of abuse including cocaine, amphetamine, nicotine, and alcohol (for review, see 38).”

    From Adolescent Neurodevelopment (2013) · cites this paper as [38]

  • Adolescent rats are often less sensitive than adults to aversive properties of both non-drug and drug stimuli, with drug effects emerging at higher doses of the same drugs that at lower doses they find more reinforcing than adults.

    “For instance, adolescent rats are often less sensitive than adults to aversive properties of both non-drug and drug stimuli, with the latter emerging at higher doses of the same drugs that, at lower doses, they conversely find more reinforcing than adults (cocaine, amphetamine, nicotine and alcohol)(38; 60; 61).”

    From Adolescent Neurodevelopment (2013) · cites this paper as [38]

  • Non-deprived adolescent rats consistently show notably less sign-tracking than adults.

    “We have found non-deprived adolescents to consistently exhibit notably less sign-tracking than adults (Doremus-Fitzwater et al, 2010; Anderson & Spear, 2011; Ung et al, 2010).”
  • The exact nature of changes in affective processing, the relation with gonadal hormones, and how they affect motivational behavior in adolescents is not yet well understood.

    “However, the exact nature of these changes, the relation with gonadal hormones, and how they affect motivational behavior in adolescents is not yet well understood (Doremus-Fitzwater et al., 2010).”

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.

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.
