Question

1. Ethnocentrism is a strong self-identification with one's race or ethnicity, often to the exclusion of other personal characteristics. 
2. Cognitive dissonance is the tension people feel when they are facing or enduring extraordinary demands, constraints, or opportunities and are uncertain about their ability to handle them effectively. 
3. Very low levels of stress lead to the best workplace performance. 
4. Stressors can be both positive and negative. 

Answer 1

1. FALSE
Ethnocentrism is the belief that one's native country, culture, language, abilities, or behavior is superior to those of another culture.
2. FALSE
Stress is the tension people feel when they are facing or enduring extraordinary demands, constraints, or opportunities and are uncertain about their ability to handle them effectively.
3. FALSE
Historically researchers have generally believed that there is an inverted U-shaped relationship between stress and performance. That is, low levels of stress lead to low performance (because people are not "charged up" to perform), but high levels of stress also lead to an energy-sapping fight-or-flight response that produces low performance. Optimal performance, according to this hypothesis, results when people are subjected to moderate levels of stress.
4. TRUE
Stressors can be both negative and positive. That is, one can understand that being fired or being divorced can be a great source of stress but so can being promoted or getting married. As Selye writes, "It is immaterial whether the agent or the situation we face is pleasant or unpleasant; all that counts is the intensity of the demand for adjustment and adaptation."
