Q

Adolescent cognition

A

middle childhood (6-11)

  • shift from “preoperational “ to “concrete logical operations” (Piaget)
  • apply rules based on observations, factor in multiple points of view, and interpret their perceptions using physical laws

early adolescence (10-13)

  • transition from concrete operational thinking to formal logical thinking
  • reason from principles, weigh many opinions, and think about the process of thinking

middle adolescence (14-16)

  • question and analyze extensively
  • understand the intricacy of the world, see beyond themselves, and use moral and legal context

classified as penetrating or nonpenetrating

nonpenetrating: minor trauma to external genitalia: lacerations or abrasions of the labia in girls

penetrating injuries: more serious/extensive and often indicative of sexual assault .

findings concerning for sexual abuse:

  • safe but boring environment
  • 1 min/yr of age (up to 5 mins)
  • if he comes out, he goes straight back in
  • usually works in 1-2 months
  • if > 5 yrs – more effective to use removal of privledges

  • walk away/ distract themselves/ separate room

4. praise for good behaviours

  • be specific
  • immediate
  • sticker charts
