Not all people will notice you and some do it intentionally.

A new study published in the Journal of the Association for Psychological Science has revealed that members of the higher class of the society tend to neglect people more compared to those who belong to the lower class.

Social psychology student Pia Dietze argues that social classes influence the differences in people's behavior around others.

"Motivational relevance" was considered in the study which describes humans as motivated to be attentive to something that they consider valuable.

The research work is composed of three individual studies involving 61 respondents whose task was to walk across the street and record the scenes with their Google Glass. The volunteers were identified according to their social classes including the upper class, upper middle class, middle class, working class and on the poverty line.

An independent team examined the recorded footages. The findings tell that class identification determines the length of time they look at individuals passing by them.

Dietze elaborated that they "usually see the most extreme differences in attention towards humans between people from the working class and the middle class, such as the working class participants pay significantly more attention to humans than their middle-class counterparts."

Another study involved the tracking of the participants' eye movements. This revealed that members of the higher class have reduced attention span.

The last experiment indicates that the behavior of the volunteers could be highly influenced by how their brain works. As part of the experiment, 400 volunteers answered an online test where they were asked to look at pairs of photos with five objects and different faces.

It was found out that members of the higher class spent more time noticing the differences in the presented faces compared to their counterparts from the lower class.

The study concluded that the interest of the members of the higher class in general public is less compared to those who belong to the lower class.
