The retention of newly-acquired brushing and flossing skills
1Los Angeles VA Outpatient Clinic, California.
Abstract:
Brushing and flossing ability increased dramatically 3 weeks following 2 sessions of oral hygiene instructions. At the same time, the plaque index for these patients decreased significantly. 1 year after the oral hygiene instruction, the plaque index for these patients returned to the pre-intervention levels. However, these patients were able to maintain their 3-week post-intervention brushing and flossing scores. We conclude that increased levels of plaque 1 year later, was not due to loss of brushing and flossing skills.

Steps in the Modeling Process
Attention is the first necessary component for observational learning. It involves focusing on what the model is doing and saying. For example, if you decide to take a drawing class to enhance your skills, you need to pay close attention to the instructor's words and hand movements. The characteristics of the model significantly...
