(CNN)Being glued to your smartphone could be causing you to make impulsive decisions and crave immediate gratification.
In fact, people who spend more time on their phones are more likely to reject larger, delayed rewards in favor of smaller, immediate rewards, according to a study published Wednesday in the academic journal PLOS ONE.
Research has long shown that a preference for smaller, immediate rewards -- what researchers call delay discounting -- is an indicator for various negative behaviors, such as drug addiction, excessive gambling, and alcohol abuse. Now, new research from Freie Universität in Berlin reveals that excessive smartphone use is also linked to impulsivity.
"Our findings provide further evidence that smartphone use and impulsive decision-making go hand in hand," said researchers Tim Schulz van Endert and Peter Mohr in a statement.
