adolescent adjudicative competence
A substantial proportion of juveniles, especially those age 15 and younger, have impairments in adjudicative competence — the capacities to understand legal proceedings, reason about legal decisions, and assist counsel — at rates comparable to adults found incompetent to stand trial; developmental immaturity itself, apart from mental illness, can diminish trial competence.

adolescent legal competence / Miranda waiver
Juveniles, especially those age 15 and younger, frequently do not adequately comprehend or appreciate the Miranda warnings they waive: as a group they understand the words of the warnings, and the function and significance of the rights to silence and counsel, less well than adults — raising doubt about whether a juvenile's waiver is knowing and intelligent.
