The most common cause of heel pain is plantar fasciitis, inflammation where this long ligament attaches to the heel bone. The pain may be sharpest when you first wake up and put pressure on the foot. Arthritis, excessive exercise, and poorly fitting shoes also can cause heel pain, as can tendonitis. Less common causes include a bone spur on the bottom of the heel, a bone infection, tumor, or fracture.
1 Observational learning, or modeling, is a type of learning most associated with the work and social learning theory of psychologist Albert Bandura.  Observational learning is thought to be particularly important during childhood.
Albert Bandura is credited with formulating the theory of observational learning. Bandura proposed that successful observational learning must include: attention, retention, motor reproduction and reinforcement. Understanding the theory of observational learning is not only helpful when it comes to cooking scrambled eggs, but it can be used to efficiently teach and learn a host of new behaviors.
