In one experiment, participants primed with words related to money were less likely to help another person who asked for their help.

Money is a commodity that is generally accepted as an economic medium of exchange. It is a medium for expressing prices and values. It circulates from person to person and country to country, facilitating trade and becoming a major measure of wealth.

Money is an item or verifiable record that is generally accepted in a particular country or socio-economic situation as payment for goods and services and to repay debts such as taxes.

The four different types of money that economists classify are commercial money, fiduciary money, legal tender, and commodity money. Money whose value is derived from the commodities that make it up is known as commodity money.
