A new study has suggested that separation from iPhone can have serious psychological and physiological effects on their users.
University of Missouri researchers say these findings suggest that iPhone users should avoid parting with their phones during daily situations that involve a great deal of attention, such as taking tests, sitting in conferences or meetings, or completing important work assignments, as it could result in poorer cognitive performance on those tasks.
Lead author of the study Russell Clayton, a doctoral candidate at the MU School of Journalism said that their findings also suggest that "iPhones are capable of becoming an extension of our selves such that when separated, we experience a lessening of 'self' and a negative physiological state."
Clayton, along with Glenn Leshner, found that when iPhone users were unable to answer their ringing iPhones while solving simple word search puzzles, their heart rates and blood pressure levels increased, as did feelings of anxiety and unpleasantness. Also, performance (number of words found on word search puzzles) decreased as compared to when iPhone users completed similar word search puzzles while in possession of their iPhones.
The researchers found a significant increase in anxiety, heart rate and blood pressure levels, and a significant decrease in puzzle performance when the participants were separated from their iPhones as compared to when iPhone users completed similar word search puzzles while in possession of their iPhones.
