iPhone separation may affect cognitive skills
When you separate someone from their cell phones, it can have a negative effect on them both psychologically and physiologically, including lowering their performance on cognitive tests, concludes a new study.
Scientists from the University of Missouri focused specifically on the effects on iPhone users of cell phone separation. The iPhone users were asked to sit at a computer cubicle and told that the purpose of the study was to test a new wireless blood pressure tool.
The participants completed two word search puzzles--one during which their iPhone stayed in their possession and the second during which they did not have their phones. The participants' phones were also called once during the second word search puzzle. While the volunteers took the puzzles, the researchers monitored their heart rates and blood pressure levels.
The researchers found several differences between results from the first test and those from the second test. When they didn't have their iPhones, the participants demonstrated elevated heart rates and blood pressure levels, and they reported increased feelings of anxiety and unpleasantness. Performance also dropped during the second test, meaning that the participants were unable to find as may words in the puzzle when their phones were taken from them.
The findings suggest that cell phone separation may have a negative impact when their owners are performing mental tasks, researchers said. They added that iPhone users may benefit from keeping their phones in their possession during demanding daily tasks, such as giving a presentation, taking a test or completing an important project.
