  Starting in the 1990s, psychological research on culture influence began to grow and challenge the universality assumed in general psychology. Culture psychologists began to try to explore the relationship between emotions and culture, and answer whether the human mind is independent from culture. For example, people from collectivistic cultures, such as the Japanese, suppress their positive emotions more than their American counterparts. Culture may affect the way that people experience and express emotions. On the other hand, some researchers try to look for differences between people's personalities across cultures. As different cultures dictate distinctive norms, culture shock is also studied to understand how people react when they are confronted with other cultures. LGBT culture is displayed with significantly different levels of tolerance within different cultures and nations. Cognitive tools may not be accessible or they may function differently cross culture. For example, people who are raised in a culture with an abacus are trained with distinctive reasoning style. Cultural lenses may also make people view the same outcome of events differently. Westerners are more motivated by their successes than their failures, while East Asians are better motivated by the avoidance of failure. Culture is important for psychologists to consider when understanding the human mental operation. The notion of the anxious, unstable, and rebellious adolescent has been criticized by experts, such as Robert Epstein, who state that an undeveloped brain is not the main cause of teenagers' turmoils. Some have criticized this understanding of adolescence, classifying it as a relatively recent phenomenon in human history created by modern society, and have been highly critical of what they view as the infantilization of young adults in American society. According to Robert Epstein and Jennifer, "American-style teen turmoil is absent in more than 100 cultures around the world, suggesting that such mayhem is not biologically inevitable. Second, the brain itself changes in response to experiences, raising the question of whether adolescent brain characteristics are the cause of teen tumult or rather the result of lifestyle and experiences." David Moshman has also stated in regards to adolescence that brain research "is crucial for a full picture, but it does not provide an ultimate explanation."
