Abstract
The task aims to test how the response time of people was affected by the number of items and color of the item. Researchers examined the response times of a group of people in a visual search task against the color and quantity of items. The participants were students at different levels of university education. The students’ responsibility was to identify an upright orange letter T among blue and orange ones. The researcher recorded their responses and analyzed the data obtained using one way ANOVA with repeated measures in SPSS software. The scholar presented their results in tables and graphs. The findings of the test showed that the particular hypothesis tested did not match.

Introduction
Generally, the more crowded a place is, the more difficult it is to spot someone. However, as people move away, one can locate the person in a less crowded area. An increase in the number of items results in an increased length in response times. The recorded data showed that every time the screen displayed more orange and blue T’s in 5,10,15, and 20’s (whether upright or up-side-down), the more each participant spent more time searching for an orange vertical T. The analysis performed was to verify if the response times were affected by color and number of items.
Psychologists suggest through various trials that it’s possible to perform an overt search if items are visibly large enough for identification. The situation is impossible without fixation (Pereira & Castelhano, 2014, p. 2058). Shifts in attention, alias covert attention, enables successful performance of numerous tasks. 3-4 times per second is approximately enough for selecting a new point of fixation. Numerous supporting studies aver that stimuli help in the selection of 4-8 items per fixation. The choice can occur in parallel or many shifts in attention per fixation.
The intended target is what determines the efficiency of a search task. Target refers to the item being searched for while its opposite is known as non-target. Beesley, Vadillo, Pearson, and Shanks (2015) enquired whether learning distractor configuration would confer a benefit on the later visual search. Participants searched for a target (T) among distractors (L) (p. 349). Distinguishing features, such as size, shape, color, orientation, number, etc. are vital in the completion of a search task. For example, red dots among yellow ones on a white paper are easy to spot out for their color. Preferably, if they happen to be bigger than the rest and fewer, a participant would have an easy task for identification. The response to such a job would increase as the number of dots increases. The above attributes are called guiding attributes because they guide attention. Jeremy and Horowitz (2008, p. 3325) came up with a modified list of characteristics and their likelihood to support a search.
The term preattentive is controversially pragmatic in many dimensions. For ...
