Episode notes
Think-Aloud Method Sparked Research Path
- Anders used think-aloud protocols in his dissertation to study problem solving in adults.
- That method led him to investigate training effects with Herbert Simon and Bill Chase.
Purposeful Practice Beats Casual Repetition
- Deliberate practice targets specific weaknesses with teacher-guided goals and repeatable activities.
- Focused practice on a chosen improvement yields far greater gains than casual play or repetition.
Autonomy Trumps Forced Early Talent
- Independence in learning matters more than early technical proficiency pushed by parents.
- Early control over training generalizes to self-directed mastery in later domains.
