Praising Without Standing

Kapitza-Dirac diffraction without standing waves: diffraction without a grating?

We discuss electron diffraction from two counterpropagating light waves with two different frequencies. We show that, even though these waves do not form a standing wave, electron diffraction similar to the conventional Kapitza-Dirac effect, i.e., scattering on a standing wave, is still possible. The nonlinear response of the electron to the laser fields creates a stationary diffraction grating...

Praising Young Children for Being Smart Promotes Cheating.

Witnessing excellence in action: the 'other-praising' emotions of elevation, gratitude, and admiration.

People are often profoundly moved by the virtue or skill of others, yet psychology has little to say about the 'other-praising' family of emotions. Here we demonstrate that emotions such as elevation, gratitude, and admiration differ from more commonly studied forms of positive affect (joy and amusement) in many ways, and from each other in a few ways. The results of studies using recall, video...

Standing balance in persistent whiplash: a comparison between subjects with and without dizziness.

OBJECTIVE Dizziness and unsteadiness, associated with altered balance, are frequent complaints in subjects suffering persistent whiplash associated disorders. Research has been inconclusive with respect to possible aetiology. This study assessed balance responses in subjects with whiplash associated disorders, taking into account several possible causes. DESIGN A prospective, 3 group, observa...
