USING ARM CUES TO ASSESS FOR

MOOD OR FEELINGS

If you establish an adequate baseline by observing a specific individual’s
arm behaviors over a period of time, you can detect how he is feeling by his
arm movements. For instance, arm movements can let you know how

to look around a lot. Second, they tended to use fewer arm movements

than regular shoppers. It was as though they were trying to make them-

selves smaller targets as they moved about the store. However, their lack

of arm movements actually made them stand out more prominently—and

essentially allowed me to better focus on them as they went about their

larcenous ways.
