The research objective for the study by Brockmole and Logie was to determine whether Visual Working Memory (VWM) is age-related. The hypothesis of the research was that visual working memory decreases with advancing age. There are different properties whose presence enables visual cognition including luminance, shape, color, orientation, size, and texture. The association of these features in memory is critical to retaining information regarding the objects observed. Increasingly. The amount of information that an individual acquires from an item is also key to creating a memory of the same object. Therefore, concerns have been raised as to whether the binding abilities of the components of an item are age-related. As the stages of development advance, the ability to observe the properties of an object and integrate the information into a working memory also decreases (Brockmole & Logie, 2013). Individuals at the extremes of age including children and the elderly have challenges that involve the visual working memory (VMW). However, teenagers and young adults who are in their twenties have better VWM.
To test the hypothesis, the researchers collected data from 55,753 volunteers from 138 different countries who were aged between 8 years to 75 years. The participants were provided with four different shapes ranging from animal forms to geometrical figures of different colors and sizes. The objects were blue, green, yellow, and red (Brockmole & Logie, 2013). The colors and shapes were also randomly combined to form customized test materials. The modified test materials were displayed using a computer screen, and the participants were required to recall the color and shape of the items. The test was stopped once the respondents failed to remember the features of the test samples. The performance was graded from 1-20 based on the number of correct objects that the participants had identified. Graphs were drawn using the statistics collected after the analysis of the responses and scores of the participants.
Using the ANOVA score script, the results showed that object retention fluctuated as a variable of advancing maturity. Memory improved from the age of 8 to 20 years and then a steady decline was observed from 20-75 years. Visual working memory for participants aged from 8-9years was similar to that of participants aged from 45-55 years (Brockmole & Logie, 2013). However, there were differences in mental retention between the male and the female participants. Color examinations showed that more memory was retained when color was involved compared to the use of shapes. The findings were similar to the existing literature on color perceptions. Moreover, the ability to detect color decreased with advancing age. Memory increased with advancing age until the middle age where there was a decline in the amount of recall by the participants. Adults displayed a decreased trend in visual working memory.
