HAPPILY, WE ATE OF THE TREE AND CRUCIFIED OUR SAVIOR...:

Guilt and Atonement on the Path to Adulthood (JOHN TIERNEY, 8/28/09, NY Times)

Guilt in its many varieties — Puritan, Catholic, Jewish, etc. — has often gotten a bad rap, but psychologists keep finding evidence of its usefulness. Too little guilt clearly has a downside — most obviously in sociopaths who feel no remorse, but also in kindergartners who smack other children and snatch their toys. Children typically start to feel guilt in their second year of life, says Grazyna Kochanska, who has been tracking children’s development for two decades in her laboratory at the University of Iowa. Some children’s temperament makes them prone to guilt, she said, and some become more guilt-prone thanks to parents and other early influences.

“Children respond with acute and intense tension and negative emotions when they are tempted to misbehave, or even anticipate violating norms and rules,” Dr. Kochanska said. “They remember, often subconsciously, how awful they have felt in the past.”

In Dr. Kochanska’s latest studies, published in the August issue of The Journal of Personality and Social Psychology, she and colleagues found that 2-year-olds who showed more chagrin during the broken-toy experiment went on to have fewer behavioral problems over the next five years. That was true even for the ones who scored low on tests measuring their ability to focus on tasks and suppress strong desires to act impulsively.

“If you have high guilt,” Dr. Kochanska said, “it’s such a rapid response system, and the sensation is so incredibly unpleasant, that effortful control doesn’t much matter.”
