5-2 Discussion: Memory Impairment
Memory loss or impairment can be difficult to deal with because it affects many aspects of life. Many factors and conditions can lead to memory loss, including strokes, head injuries, drug use, depression, Parkinson's disease, and dementia. Conduct a little research, and report on two different types of memory loss. Compare and contrast changes in the brain and memory that occur with each type of memory loss. After discussing specific types of memory loss, provide a few suggestions for improving memory based on what you learned about memory systems in this week's readings.

Discussion questions will help you make meaningful connections between the course content and the larger concepts of the course. These discussions give you a chance to express your own thoughts, ask questions, and gain insight from your peers and instructor.
Directions
For each discussion, you must create one initial post and follow up with at least two response posts.
For your initial post, do the following:
- Write a post of 1 to 2 paragraphs.
- In Module One, complete your initial post by Thursday at 11:59 p.m. Eastern.
- In Modules Two through Ten, complete your initial post by Thursday at 11:59 p.m. of your local time zone.
- Consider content from other parts of the course where appropriate. Use proper citation methods for your discipline when referencing scholarly or popular sources.
For your response posts, do the following:
- Reply to at least two classmates outside of your own initial post thread.
- In Module One, complete your two response posts by Sunday at 11:59 p.m. Eastern.
- In Modules Two through Ten, complete your two response posts by Sunday at 11:59 p.m. of your local time zone.
- Demonstrate more depth and thought than saying things like “I agree” or “You are wrong.” Guidance is provided for you in the discussion prompt.

Memory
For most people, memory is an important topic because many of us are interested in finding ways to improve our memory. In cognitive psychology, when we consider memory, we not only want to understand why someone cannot remember where their keys are. We also want to understand the cognitive systems that exist for memory. In looking at memory systems, we see that there are different types of memory. There are also different factors that influence how well each system or type of memory works. The biggest distinction in memory systems is the difference between short- and long-term memory. Short-term memory holds information for a relatively short period of time and has a limited capacity. For example, if you were going to the store, you might be able to keep the items milk, bread, and eggs in your short-term memory while you were shopping. In a classic experiment, Miller (1956) found that the capacity for short-term memory is about seven, plus or minus two items. However, this capacity can be increased by using different strategies. One strategy would be chunking. In chunking, we group items together. For example, if someone told you that his phone number is 859-3658, Miller’s theory would predict that you could keep those seven digits in short-term memory with no trouble. However, if you wanted to remember those seven digits plus additional information, you might group the numbers together as 859, 36, and 58. In contrast to short-term memory, long-term memory has an unlimited capacity. Information can be held in long-term memory for long periods of time—perhaps even forever. Information moves from short-term memory to long-term memory when we rehearse it and use it repeatedly. For example, when learning another language, the more you use the language, the better your memory for the rules of grammar and vocabulary. However, just because we practice using information does not mean that we will successfully store it and recall it later. In the module readings, you will see that long-term memories can be affected by many things. Prior experiences, interference from other learning, sleep, stress, emotion, or the context within which we learn the information may affect long-term memory
Another form of memory important for cognitive psychology is working memory. The term working memory is sometimes used to refer to short-term memory. However, as noted in the module readings, working memory is different from short-term memory. The concept of working memory was introduced by Baddeley and Hitch (1974). According to their model, working memory includes several components that allow memory to respond to incoming information. We then activate information from long-term memory. In this way, we can process incoming information. Then, we can “work” on this information by associating it with information previously stored in long-term memory. For example, if you are completing a math problem, parts of your working memory will be responding to the numbers that you are dealing with. Other parts of it will be accessing stored long-term memories for rules of how to solve that math problem. In the years since this model was created, much research has been conducted related to working memory. Researchers today have been able to identify brain areas that are involved in different aspects of working memory. (See Baddeley 2000 and Baddeley 2003 for a review of the brain areas involved). Research has also identified working memory as a potential predictor of academic success. Alloway and Alloway (2010) found that a child’s working memory capacity predicted his or her skills in reading, spelling, and math. They also found that “working memory at the start of formal education is a more powerful predictor of subsequent academic success than IQ during the early years” (p. 26).
We’ve learned about how memory systems work from examining individuals with amnesia. The famous case is Henry Molaison. He is known more commonly to the world of psychology as simply “H.M.” This case has helped us uncover an incredible amount of information about memory. H.M. underwent a procedure to correct epilepsy. During the procedure, doctors removed part of his temporal lobe, which included the hippocampus. After the procedure, he lost the ability to consolidate new long-term memories. This left him with anterograde amnesia. In anterograde amnesia, an individual can recall events from before the amnesia occurred. For example, H.M. could remember his childhood. But they are unable to create new memories. For H.M., the inability to create new memories seemed to be isolated to events that happened to him and not the learning of new procedures. For example, H.M. could not remember the names of individuals he interacted with, but he was able to learn new motor tasks at a normal rate (Blakemore, 1977). These findings helped researchers understand the difference between explicit and implicit memory. Explicit memory refers to conscious memories for knowledge and experiences. Implicit memory refers to memory for how to do something. Research has made great strides in understanding how memory systems in the brain work. Yet, it is important to note that there are no specific brain areas that store all our memories. Instead, memories are stored throughout the brain, and their storage is in part determined by how they were encoded. For example, if you have a visual experience with something, it is likely to be stored in the visual areas of your brain. A final point to consider about memory is its fallibility. We may be confident about how a certain event occurred. Yet research indicates that memories can be consolidated incorrectly or changed through suggestion. Elizabeth Loftus is a cognitive psychologist. Her research program has illustrated that false memories can be planted in individuals (Braun et al., 2002). Memories can also be altered by misleading information (Loftus, 1977).
Understanding the details of memory will help prepare you for learning about how the information in memory is used for problem solving and decision making in future modules. It can also help you understand your own cognitions and memory. Through the study of memory, you can begin to identify and use strategies that will improve your memory in your daily life and in this course.
