Chapter 7, 8, & 9 1. Compare and contrast the Information Processing Approach, the Parallel Distributed Processing Model, the Levels of Processing Model, and the Traditional Three-stage Memory Model.
Information Processing Approach- states that memory is a process, analogous to a computer, where information goes through three basic processes-encoding, storage, and retrieval
Parallel Distributed Processing Model- states memory is distributed across a wide network of interconnected neurons located throughout the brain. When activated this network works simultaneously to process information
Levels of Processing Approach-states memory depends on the degree or depth of mental processing occurring when material is initially

Identify empirical findings regarding location of memory in the brain. 6. Differentiate between retrograde and anterograde amnesia; and describe the symptoms, causes, and potential treatments for Alzheimer’s disease.
Retrograde is when old memories are lost
Anterograde is when new memories cannot be formed
AD is progressive mental deterioration characterized by severe memory loss- characterized by a build-up of proteins in the brain. - cholinesterase inhibitors 7. Describe theories of forgetting, and differentiate between proactive and retroactive interference.
Decay Theory-Memory degrades with time
Interference Theory-One memory competes with another -Retroactive interference ( new information interfers with old) -Proactive Interference(old information interferes with new)
Motivated Forgetting-motivation to forget unpleasant, painful, threatening, or embrassing moments
Encoding failure-information in STM is encoded in LTM
Retrieval Failure-memories stored in LTM are momentarily inaccesible
8. Discuss forgetting and describe how
Low levels of processing include operations like counting the letters in words and higher levels of processing might include forming semantic relationships such as understanding what the words’ meaning is. According to Craig and Lockhart who formulated this theory memory recall would improve as the information is processed in greater depth. However it has been hard to define exactly what depth is and it has been found that there are other factors that make people remember things. (Zachmeister, E.B., Nyberg 1982)
This had led psychologists within the approach to explain that memory is build up of three stages: encoding (where information is received), storage (where the information is held) and retrieval (where the information is recalled if necessary.)
* Levels of processing theory- proposes that deeper levels of processing results in us remembering information for a longer period of time
Memory refers to the processes that are used to acquire,store,retain and later retrive information. There are three major processes involved in memeory ; encoding,storage,retrieval.
Working Memory is STM. In contrast to the Multi-Store Model, where all the information goes to one single store (Unitary store), there are different systems for the different types of information. Working Memory consists of
Throughout history there have been reports of decreased memory and mental deterioration that accompanied old age. Alzheimer’s disease (AD) was named after Dr. Alois Alzheimer who described the symptoms in a woman in Germany in the 1907 but it was not until the 1970’s that AD was considered to be a major disorder and AD continues to be a major health concern worldwide (Reger, 2002).

B. the central executive directs the flow of information in the cognitive system unconsciously. C. long-term memory is limited in capacity. D. sensory information is represented directly and briefly in the short-term memory without being filtered by attention. Reset Selection
Alzheimer’s disease (AD) is a progressive and fatal form of dementia, frequently seen in the elderly altering their cognition, thought process and behavior. AD is reported in about half of patients that have a dementia diagnosis; one study states that about 10.3% of the population over 65 years is affected by dementia with an increase to almost 50% over the age of 85. (Beattie, 2002) Alzheimer’s disease is not a normal part of the aging process in humans, but rather found in a group of diseases that affect the brain leading to a decline in mental and physical control. AD when diagnosed has a very slow and gradual course, initially affecting the individual’s short term memory. (Beattie, 2002)
Research has shown that there is “greater activation in the left inferior frontal and medial temporal lobes” (Stanford, 2006, p. 208) during the encoding of words which were later remembered as compared to those which were forgotten. The sensations perceived by sensory nerves are decoded in the hippocampus of the brain into a single experience (Mastin, 2010). The hippocampus analyses new information and compares and asssociates it with previously stored memory (Mastin, 2010). Human memory is associative in that new information can be remembered better if it can be associated to previously acquired, firmly consolidated information (Mastin, 2010). The various pieces of information are then stored in different parts of the brain (Mastin, 2010). Though the exact method by which this information is later identified and recalled has yet to be discovered, it is understood that ultra-short term sensory memory is converted into short term memory which can then later be consolidated into long term memory (Mastin, 2010).
Alzheimer’s disease, also referred to as AD, is a form of dementia that affects millions of people worldwide. AD is best known for causing memory loss in those who suffer from it, as well as affecting decision-making, language, and decision making progressively over time (Zou et at, 2014). According to Zou et el (2014), the symptoms of AD are caused by a build of plaques in the neurons of the brain. Alois Alzheimer discovered the disease, which was later named after him, when a woman at the age of 51 presented to him with a case of dementia that was new to him. Alzheimer was able to deduce the behavior of the woman with certain cognitive features, as well as through autopsy proceedings, that the symptoms were caused by “senile plaques” within

The first process of memory is attention. There is much more information around you than you can process at any one time. Thus, you must make choices (conscious and unconscious) regarding the information you will remember. Once information is acknowledged, it needs to be encoded in order to be remembered. Encoding refers to translating incoming information into a trigger
● Information processing - The theory states that at the time information is presented to the
Prior to the early 1970s the prominent idea of how memories were formed and retrieved revolved around the idea of processing memory into specific stores (Francis & Neath, 2014). These memory stores were identified as sensory memory, short-term memory, and long-term memory. In contrast to this idea, two researchers named Fergus Craik and Robert Lockhart proposed an idea linking the type of encoding to retrieval (Goldstein, 2015). This idea is known as the levels of processing theory. According to this theory, memory depends on the depth of processing that a given item is received by an individual (Goldstein, 2015). Craik and Lockhart stressed four points in supporting their theory. First, they argued that memory was the result of a series of analyses, each level of the series forming a deeper level of processing than the preceding level (Francis & Neath, 2014). The shallow levels of processing were believed to hold less importance and are defined as giving little attention to meaning of an item. Examples of which include focusing on how a word sounds or memorizing a phone number by repeating it over and over again (Francis & Neath, 2014) (Goldstein, 2015). The deeper levels processing involve paying close attention to the meaning of an item and relating that meaning to something else, an example of which would be focusing on the meaning of a word rather than just how the word sounds (Francis & Neath, 2014) (Goldstein, 2015). The second point Craik and Lockhart
Memory is defined as "the persistence of learning over time through the storage and retrieval of information." Our memory can be compared to a computer's information processing system. To remember an event we need to get information into our brain which is encoding, store the information and then be able to retrieve it. The three-stage processing model of Richard Atkinson and Richard Shiffrin suggests that we record information that we want to remember first as a fleeting sensory memory and then it is processed into a short term memory bin where we encode it ( pay attention to encode important or novel stimuli) for long-term memory and later retrieval. The premise for the three step process is that we are unable to focus on too much
