Visual Short-Term Memory Analysis

Research effort in the past decade has focused primarily on the representation of a single visual display (Jiang et al., 2005). In this article, researchers were trying to compare how good humans are at integrating sequential displays in visual short-term memory. The task was conducted by using trials of sequential arrays on a computer. The first array was a cell with seven black dots on random squares in which the participants would have to memorize the location of the black dots. In addition, they would then be given an empty matrix where they would need to click on the box corresponding to those black dots from the previous matrix that they were looking at. Same goes for the second array, but with more black dots. The third and final procedure was based on 16 letters in where the participant would memorize it and then type the letter in the box where it belonged based …show more content…
This article is an example of an experimental research which also had a controlled variable. The key variables that were found in this research were as follows: VSTM, limited capacity, image-perception integration, and limited integration. How good humans are of integrating sequential arrays would be known as the independent variable. As for the dependent variable, it would be visual short-term memory. It was proposed that although VSTM supports effective comparison between simple representations, it does not support the creation of an entirely new representation on the basis of two separate images (Jiang et al., 2005).
The target population was based on eight college students from the ages 19-28. According to the article, these students chose to participate in this study because of some form of payment that was arranged, in which the article does not go into details with. The sample was based on simple random sampling since it was a very small population from a college. Sampling procedures can be improved by selecting random sampling with a larger population to receive more accurate
