Smartphone use may make you wussy, says Harvard study
Harvard study shows that the size of a device, and your body posture using it, influences your behavior and demeanor.
Your reputation as a tough, hard-nosed business go-getter may take a hit if you spend a lot of time using your little smartphone. A study conducted by researchers at Harvard Business School suggests that using devices with small screens can cause people to behave less assertively than those using larger screens.
"Grounded in research showing that adopting expansive body postures increases psychological power, we hypothesized that working on larger devices, which forces people to physically expand, causes users to behave more assertively," reads the abstract of the paper, titled "iPosture: The Size of Electronic Consumer Devices Affects Our Behavior."
The study used 75 participants who were randomly assigned to perform tasks on various devices. The researchers chose to go with Apple products representing a range of sizes, though the results could be extrapolated to other brands. Participants used an iPod Touch, an iPad, a MacBook Pro, or an iMac.
Once the tasks were finished, the researcher told the participant, "I will be back in five minutes to debrief you, and then pay you so that you can leave. If I am not here, please come get me at the front desk." The researcher then waited up to 10 minutes to return. Participants who had been using smaller devices took longer to go fetch the researcher than those using larger devices.
The researchers trace this correlation to the body posture people adopt when using devices. Smartphones and tablet users tend to hunch over their devices and contract their bodies. Desktops users tend to have a more open posture."Participants interacting with smaller devices were less assertive than participants interacting with larger devices," says the study.
The paper concludes with a bit of advice. "Many of us spend hours each day interacting with our electronic devices. In professional settings we often use them to be efficient and productive. We may, however, lose sight of the impact the device itself has on our behavior and as a result be less effective. We suggest that some time before going into a meeting, and obviously also during it, you put your cell phone away."
