Some people hate change and so cling desperately to what they know. They find comfort in routines, even if those routines no longer produce what is needed. Instead, according to Price Pritchett and Ron Pound in The Employee Handbook For Organizational Change , some employees merely want to hang on to the familiar, to snuggle into the comfort of what they already know.

People like to feel in control. And generally they dig in their heels because they're afraid of the unknown, rather than being in love with the way things have been.

But in this day and age of seemingly constant change it's a good thing to consider how you react to change. Does ambiguity make you nervous? If so, you're probably going to have to do some work to let go of your grip on the past.

We've all scratched an itch and felt better for it. But why do we get relief?

Scientists uncovered an answer with magnetic resonance imaging (MRI) in a study where participants were scratched with a small brush – 30 seconds on and 30 seconds off – for a total of about five minutes. Researchers were surprised when areas of the brain that are associated with unpleasant or aversive emotions and memories became less active when participants were being scratched.

Asking your kids about their school day is a good idea. Why? Researchers who study how kids learn already knew that children learn best with their parents or a peer, but it wasn't clear whether this was because the children were getting feedback and help, or merely because they were explaining their solutions to someone. In a recent study, researchers had mothers simply listen to their children without providing any assistance.
