Robert Plutchik agreed with Ekman's biologically driven perspective but developed the "wheel of emotions", suggesting eight primary emotions grouped on a positive or negative basis: joy versus sadness; anger versus fear; trust versus disgust; and surprise versus anticipation. Some basic emotions can be modified to form complex emotions. The complex emotions could arise from cultural conditioning or association combined with the basic emotions. Alternatively, similar to the way primary colors combine, primary emotions could blend to form the full spectrum of human emotional experience. For example, interpersonal anger and disgust could blend to form contempt. Relationships exist between basic emotions, resulting in positive or negative influences.

What is the name of the theory Plutchik created?
Answer: wheel of emotions

The central government estimates that over 7,000 inadequately engineered schoolrooms collapsed in the earthquake. Chinese citizens have since invented a catch phrase: "tofu-dregs schoolhouses" (Chinese: 豆腐渣校舍), to mock both the quality and the quantity of these inferior constructions that killed so many school children. Due to the one-child policy, many families lost their only child when schools in the region collapsed during the earthquake. Consequently, Sichuan provincial and local officials have lifted the restriction for families whose only child was either killed or severely injured in the disaster. So-called "illegal children" under 18 years of age may be registered as legal replacements for their dead siblings; if the dead child was illegal, no further outstanding fines would apply. Reimbursement would not, however, be offered for fines that were already levied.

What catch-phrase was invented as a result of collapsed schools?
Answer: tofu-dregs schoolhouses
