Donald Broadbent’s theory claims that every person has a filter device which is used to register information or stimuli and which is located between the storage of short-term memory and the incoming sensory register. Based on Broadbent’s theory, this filter works hand-in-hand with a buffer, and allows one to manage two types of stimuli. One stimuli input passes through the filter while the other input is held in the buffer to be processed later. Basically, the key role of the filter is to prevent the overloading of the short-term memory as it has limited capacity.In short, this device mainly functions in order for humans to focus their attention on a single information, thing, or stimulus while the others are stored in the short-term memory. On the other hand, the modified filter theory which was proposed by Anne Treisman. According to Treisman’s theory, instead of only one filter, there are several filters or tests, which include one that handles grammar, patterns of syllables and semantic meaning of words.When the various information and stimuli fail to get through these filters or tests, they become attenuated or weakened so that there would be less interference with the selected information or messages, but these would not be discarded until it passes through the final filter, which overall examines the semantic meaning of the inputs. Generally, the main difference between the two is that Broadbent’s theory used only a single filter which chooses the information that would register while Treisman’s theory used several filters and a final filter which would decipher the overall meaning of the inputted message.In this regard, it is Treisman’s theory that best accounts for people’s methods of selecting what particular types of information they would focus their attention to because it is very broad compared to Broadbent’s theory, which is limited to only a single filter. The modified filter theory explains how multiple types of stimuli are handled as it goes through the sensory registers while Broadbent’s theory fails to do so because of its several limitations. In addition, Broadbent’s theory also cannot explain how emotionally charged words are registered.

City o Choice: Gilbert in the state of Arizona (do not use any other city)
For this discussion, you will use a census website that posts information on variables observed in the city where you live. Here is the website address. https://www.census.gov/acs/www/data/data-tables-and-tools/data-profiles/2017/ (Links to an external site.)
(Links to an external site.)After you open the website, you can enter the name of my state of Arizona on the left at the bottom and the name of my city of Gilbert on the right of the landing page. You will see links to 4 sets of information on your area: social, education, housing, and demographic. You will be assessing the change in one variable you select for two different years. For example, data from the entire United States could be used to compare the percentage of women never married for the years 2010 and 2017.
Once you have selected your variable and obtained the information, answer the following questions:
Was there a difference in the values of your variable?
How would you write the null hypothesis if you wanted to test the differences statistically?
Does the difference appear to be a significant one? How would you substantiate that?
Is the difference important?
What are the consequences of the change in your values for your community? For example, a significant increase in the number of women never married could affect the birth rate. It could also mean more women are attending college and becoming self-sufficient.
