Final answer:
Adolescents are the age group that is acquisition oriented.
Step-by-step explanation:
The age group that is acquisition oriented by its very nature is adolescents. Adolescence is a time of rapid cognitive development, and by the age of 15, many adolescents have basic thinking abilities comparable to those of adults. They demonstrate similar levels of attention, memory, processing speed, and organization. Cognitive development may continue into the early 20s as increasing capacity for insight and judgment develops through experience.
