Behavioral cusps are pivotal skills (e.g., reading, imitation) that, once acquired, dramatically expand a learner's access to reinforcement and further learning.

Question 4

During which developmental phase does pruning of synaptic connections occur most dramatically, refining neural efficiency?

Accepted Answer

Adolescence

Answer

Synaptic pruning—elimination of unused neural connections—peaks during adolescence, strengthening frequently used pathways.

Question 5

Vygotsky's zone of proximal development (ZPD) is best applied in ABA by:
