Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? During a Go-Stop task, the indirect frontal-basal ganglia pathway was involved in response inhibition in controls but not in Internet-addicted adolescents, who instead activated the left superior frontal gyrus. → Marciano Laura 2021
Evidence¶
Marciano Laura 2021¶
Marciano Laura, Camerini Anne-Linda, Morese Rosalba. (2021). The Developing Brain in the Digital Era: A Scoping Review of Structural and Functional Correlates of Screen Time in Adolescence. Frontiers in Psychology. https://doi.org/10.3389/fpsyg.2021.671817
q3 · i? · review · r3
Task-based fMRI Go-Stop study of 18 Internet-addicted and 23 control adolescents aged 15; the review reports the authors' conclusion that Internet-addicted adolescents "showed a deficient response in inhibition because they most likely failed to recruit the neural correlates." No effect size printed.
"the comparison of their fMRI results indicated that the indirect frontal-basal ganglia pathway was involved by response inhibition in the control group, but not in the Internet-addicted group. The latter group showed instead activation of the left superior frontal gyrus."
Discussion¶
Related Claims¶
- Excessive smartphone use in adolescents is associated with reduced frontostriatal connectivity and greater cortisol-related withdrawal symptoms
- Adolescents with Internet addiction show structural and resting-state functional brain alterations, including reduced gray matter density, reduced white matter FA, and decreased connectivity in DMN and CEN
- Frequent and longer screen-based media use, including Internet-related addictive behaviors, is related to a less efficient cognitive control system in adolescence — a broader claim this one bears on
