For millions of Facebook users, choosing which photo to use for an online profile is an important decision. According to a study by researchers at the UT Dallas Center, the photos we select may reflect individual preferences, but they also appear to reflect more deeply rooted, unconscious cultural differences. Previous research has shown that culture can affect not only language and custom, but also how we experience the world and process information. Western cultures, for example, condition people to think of themselves as highly independent entities （实体）, whereas East Asian cultures stress collectivism and interdependence.

Dr. Denise Park, co-director of the Center at UT Dallas, and former graduate student Dr. Chih-Mao Huang of the University of Illinois, were curious about whether these patterns of cultural influence extend to cyberspace. In a paper published in the International Journal of Psychology, they examined the profile photographs of more than 500 active Facebook users from the United States and East Asia. Overall, they found that profile photos of Americans are more likely to focus on the individual's face, while the profiles of East Asians tend to less emphasize the face and include more background features. Americans also show greater smile intensity compared to East Asian Facebook users.

The findings show marked cultural differences in the focus of attention among East Asian and American Facebook users. Moreover, they echo previous research on cultural influences on visual perception（感知）, attention, and reasoning in the offline world.

"We believe these findings relate to a cultural bias to be more individualistic and independent in the US and more communal and interdependent in Asia," said Park.

The research also found that cultural influences over our self-presentation online can shift over time and from place to place. In one of the study samples, Americans studying in Japan and Japanese studying in the United States both showed a tendency to adjust their profile photos to the general preferences of their host country.

"Facebook constitutes an extended social context in which personal profiles mirror various individual characteristics, private thoughts, and social behaviors," noted Huang. "As such, the study presents a new approach to investigate cognition and behaviors across cultures by using Facebook as a data collection platform."

In one of the study samples, Americans studying in Japan showed a tendency to adjust their profile photos to the general preferences of their host country because they want to maintain a good relationship with their Japanese friends.

6 . In many cultures, it is considered unlucky to spill salt. Fortunately, many cultures also have a solution to the problem, which usually involves throwing a pinch of salt over your shoulder. It may seem confusing to modern humans, but knowing that salt was once incredibly valuable can change this perspective.

For thousands of years, salt was an extremely rare commodity. It was difficult to obtain so that the price was very high. Many trading routes were set up to carry salt, people were paid in salt, and salt was sometimes worth more than its weight in gold. Therefore, spilling salt was considered wasteful.

Because of its high value, salt was also associated with friendship and good fortune. Offerings of salt were included in many religious ceremonies, and people might bring salt to a new home for good luck. These associations would have suggested that it would be bad luck to spill salt, since it would seem to violate salt’s fortunate properties.

Salt is also an excellent preservative. It prevents food from going bad. As such, it came to be linked with health and longevity. In some cultures, spilling salt was thought to reduce one's well-being. In Britain, for example, each spilled grain was said to represent a tear, while in Germany spilled salt awakened the devil, bringing misfortune.

The fear of spilling salt was also adopted into the Christian faith. It is said that Judas spilled salt at the Last Supper, and since he later turned out to be the betrayer of Christ, spilled salt is considered unlucky by many Christians.

Should you be unfortunate enough to spill salt, you might throw a pinch over your left shoulder to blind the Devil.
