______________indicated that infants and children may be particularly sensitive to good environments; so much so that kids with attention deficit disorder (ADD) or attention deficit disorder with hyperactivity (ADHD), ( and other subgroups of kids) may excel beyond other age mates (just like orchids) if they experience a positive environment. In the wrong environment, however, these children may be significantly impaired and really harmed (more than others). Children who do relatively well in most environments may not have as many sensitivity genes (like dandelions).
