Psychologist joanne wood and her colleagues recruited people with high and low self-esteem to participate in a study of positive self-statements (wood, perunovic, & lee, 2009). they asked participants to write their thoughts and feelings down for 4 minutes. they randomly assigned half the participants to repeat to themselves a positive self-statement, "i am a lovable person", at 15-second intervals (cued by a bell sound). the other half did not repeat this phrase. after the 4-minute session, all participants rated their mood on a subtle mood questionnaire. here are the results: [see table above]

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
