The Hippocampus and Working Memory and
Their Effects on Object Location and Recognition

I.Discuss one cognitive process that is crucial to you as part of an everyday activity. A. Introduce the everyday activity
I have noticed over the years through conversations, observation, and experiences that I am very poor at remembering directions and where objects are located. This has always troubled me and quite frankly, annoyed me as my friends and peers have no issues regarding the matter. I have always wondered what the problem was, if it meant anything, and why it even existed. This problem exists on a small scale and a large scale. Whether it is remembering where I last put my keys, or where my pencil is; I just seem to have a greater amount of difficulty than those around me. On a larger scale, I also seem to always need to ask for directions to places that I have been numerous times and lack the ability to recognize objects that should be familiar due to the amount of exposure I have had to them. This exists when I am physically attempting to complete a task (finding a pencil, or locating the local bank) and when I am trying to picture the solution in my mind. B. Identify one major component cognitive process

This topic involves what has become a widely studied and extremely important cognitive process: working memory. This is our brains ability to momentarily preserve mental depictions that are significant to the execution of a cognitive task at hand. In order for information to be stored in our long-term memory, it usually but not always passes through our working memory first. Our working memory consists of three basic compartments which are called: the central executive, the phonological loop the visuo-spatial sketchpad and the episodic buffer (Kellogg, 2012, p.119). When attention is given to a particular object or set of information, the central executive governs this process. This information is then guided through the phonological loop, the visuo-spatial sketchpad, and the episodic buffer. The phonological loop is an extremely important component in this process of memory. It involves soundlessly repeating information by the means of words and sounds in a loop. Hence the term phonological “loop”. Then we have an area special for storing visual and spatial information, which has been named the visuo-spatial sketchpad. You might think of a blank tablet on which we create our own images or visual and/or spatial information that we wish to store and remember; hence “sketchpad.” To be blunt, it holds information about what we see and wish to store or remember. This visuo-spatial sketchpad involves much of the issues in which I have struggled with regarding directions and object locations. Lastly, in working memory we have a component called the episodic buffer, which connects all of this information that we wish to store, throughout areas of visual, spatial and auditory information. C. Information relevant to understanding the process

Due to the issue at hand, I will focus mostly on the visuo-spatial sketchpad. Because it involves painting a picture within our memory of where objects are located we can also recognize that it has a lot to do with our cognizance of where we are located in relation to things around us. An example and potential personal application of this concept might include asking yourself certain questions like: How many apples were left in the fridge last time you looked? How many drawers does your dresser have? Or which cupboard are the glasses in? We all find ourselves picturing the inside of the fridge, or the dresser in our bedroom, or our kitchen cabinets in order to find an answer to these visually and spatially oriented questions. We must find the images on our sketchpad to ultimately provide an accurate answer. II.Summarize and Critique a relevant research article
