Neurotic people tend to upload more photos on Facebook to feel noticed and earn more "likes," study says.

Researchers have found out how Facebook profiles can be used to identify certain personality traits, such as neuroticism and extroversion.

Although both upload a significant number, neurotics are known to upload more pictures per album while extroverts apt to change their profile cover photos, according to the recent study reported in a news website Live Science.

A team of researchers from England's University of Wolverhampton recruited 100 people between ages 17 and 55 to complete questionnaires about their personality and demographics.

The sample group was randomly chosen but it has little over 70 percent women participants. The team then observed each individual's behavior, concentrating on photo uploading activities and interactions.

The connection between extroversion and the tendency to upload more photos may be predictable. But how can the same idea be applied in neurotics, who are "prone to stress and anxiety" as described by the researchers?

The results show that neurotics search for acceptance to look more attractive and popular online by intensive photo uploads, the author of the study Azar Eftekhar told Live Science.

She added that neurotics strongly desire strong approval granting that they may not communicate well and may lack social skills. Being socially anxious, they may perceive Facebook as a safe place to express themselves and to compensate for their offline deficiencies.

Moreover, the research also figured out that conscientious people upload more videos and created more "self-generated" albums, which are defined as any collection of photos that are not automatically created by Facebook.

Conscientious individuals are self-disciplined and goal-oriented, which will likely make them use online visual tools to organize and document their photos and videos, Eftekhar said.

The study was published in the August issue of Computers in Human Behavior, a journal that specializes in examining the psychological effects of computers on people.
