The first stage in the perceptual process is called and refers to the process of bringing some stimulus within the proximity of a consumer so that it can be sensed by one of the five human senses.

selection

Explanation:

Selection is the mechanism that we have , for knowing what things to put our attention and focus while ignoring the rest or regarding them as irrelevant.

Every person has its own perception but in any case a selection makes some stimuli relevant while disregarding the many others present in the environment.

It would be otherwise impossible for brains , and we also have an amazing unconscious capacity that pick and cooses what is deemed relevant for us.

While picking some stimuli , selection is influenced heavily by our  motives, incentives, inner drives or basic instincts.

This often is why we are "predisposed" to see things in such a way, and it also makes us most eager to act based on specific stimuli.

Of course this has a long history since we as human species have adapted mechanisms in our effort to survive.

uses : -

1.aneroid barometers primarily measure whether pressure is rising or falling.

2.aneroid barometers are often used for reading pressure in homes and recreational boats.  

3.other uses may include barographs in meteorology and altimeters in modern aircraft.  

4.this type of barometer can announce whether a high or low pressure system is coming or whether it is becoming more intense.  

5.there are different types of aneroid barometers, such as the altimeter, which measures altitude, or distance above sea level.  

6.another example is a barograph, which is a modified aneroid barometer that provides constant readings of atmospheric pressure on graph paper.  

7.when used in this capacity, the aneroid barometer can store a week's worth of data.

android diameter a device for measuring atmospheric pressure , often specially calibrated for use as an altimeter ,consisting of a box or chamber partially exhaused of air, having an elastic top and a pointer to indicate the degree of compression of the top caused by the external air
