Elena and Clara are highly competitive twin sisters. To prepare for a major national youth orchestra audition, they practice scales and difficult concertos late into the night. Their music academy teacher rewards high performance in weekly assessments by giving them premier solo slots in upcoming concerts, and also waives their chore of cleaning the rehearsal rooms if they score above 95%.
Outside of music, both sisters compete in track sprint races at a regional club. Their coach heaps public praise on them when they win. In a recent championship 100m sprint, Elena won first place and Clara came second. Elena was cheered enthusiastically and hugged by a group of popular male peers from their school. Clara flew into a rage, violently threw her running spikes at the ground, and screamed insults at Elena before storming off.
Evaluate how far operant conditioning and the role of hormones could explain Clara's and Elena's behaviour.
