One hundred and forty two undergraduate students participated in a levels-of-processing experiment on the basis of Craik & Tulving’s (1975) famous model. Participants were presented with shallow, intermediate or semantic words within 60 judgment trials, followed by a recognition test of 120 trials containing half of the original words. The findings suggest that participants recognized the semantic words better compared to the shallow and intermediate words; this proposes that by the use of attention, semantic processing leads to a stronger memory trace. Possible explanations and future research regarding levels of processing are discussed.
The levels of processing have become a central phenomenon in cognitive psychology in the last several decades. In everyday tasks, one may not realize that he or she is using the semantic processing for deeper analysis of the story. For example, when reading a novel, it comes naturally and is most likely stored into long-term memory for recall (Craik& Lockhart, 1972, p. 680); that way when the person is discussing about that novel in conversation, it is easy to remember important facts or characters without having to go back and confirm. Craik and Lockhart (1972), as cited in Glanzer, 1972, p. 680) highlighted that in free recall, variables such as presentation rate, and word frequency, affect long-term but not short-term retention. In a positive and negative recall in both incidental and intentional learning environments performed by Craik & Tulving (1975, pg.276), it was concluded that deeper level processing requires more time, but the qualitative nature of the task determines the level of recall. As a result attention is required when focusing on a certain task.

...Baddeley (1966) study of encoding in the short term memory and long term memory supports the MSM model on the mode of processing such that words are processed on recall and both models share the same opinion that processing does influence recall. Finally, the MSM model of memory states that all information is stored in the long term memory, however, this interpretation contrasts with that of Baddeley (1974) who argue that we store different types of memories and it is unlikely that they occur only in the LTM store. Additionally, other theories have recognised different types of memories that we experience, therefore it is debatable that all these different memories occur only in the long-term memory as presumed by the multi-store model which states the long term memory store as with unlimited capacity, in addition it also fails to explain how we recall information.
Ebbinghaus’ work on memory performance contributed astonishing knowledge to the field of scientific psychology and enthralled several succeeding researchers and psychologists (Fuchs, 1997; Slamecka, 1985; Young, 1985). Ebbinghaus was precisely known for conducting memory experiments by using nonsense syllables, and from the results of those experiments, he postulated a unitary view of learning and memory. However, Endel Tulving, provided evidence from Ebbinghaus’ original research that there existed discernible kinds of learning and memory. Prior to his experiment, Tulving received some scathing criticism on his stance regarding Ebbinghaus’ research, but he averred that there was no intention to derogate its concept (Slamecka, 1985; Tulving, 1985). Rather, Tulving’s experiment emanated from Ebbinghaus’ original research to address implications that would supplement knowledge about the psychological science of memory.
In the experimental group the middle four average scores were not significantly different (M = 0.70, SD = 0.04) from the last four average scores (M = 0.50, SD = 0.00), t(4) = 2.06, p < ns . In the control group, the middle four average scores were also not significantly different (M = 0.68, SD = 0.02) from the last four average scores (M = 0.56 , SD = 0.00), t(4) = 1.89, p < ns.The serial position curve of recall of the warned group and the control group showed a similar pattern as to the one found in previous studies on the same topic. Both groups were able to recall about 90% of the words in the beginning of the list and the end of the list (See Figure 1). The warned group had slightly more false memories, but the difference was not at all significant (see Figure 2). The control group recalled more critical and studied words than the warned group (see Table
Human memory is flexible and prone to suggestion. “Human memory, while remarkable in many ways, does not operate like a video camera” (Walker, 2013). In fact, human memory is quite the opposite of a video camera; it can be greatly influenced and even often distorted by interactions with its surroundings (Walker, 2013). Memory is separated into three different phases. The first phase is acquisition, which is when information is first entered into memory or the perception of an event (Samaha, 2011). The next phase is retention. Retention is the process of storing information during the period of time between the event and the recollection of a piece of information from that event (Samaha, 2011). The last stage is retrieval. Retrieval is recalling stored information about an event with the purpose of making an identification of a person in that event (Samaha, 2011).
Similarly, even when an individual’s attention is supposedly devoted to a target item, subsequent memory can suffer when the initial coding of the item takes place at shallow level. This effect has been suggested in studies examining the “depth of processing effect” (Cr...

... learning, stuck in time hypothesis and usage of semantic memory. A problem we encounter in coming up with one solution is that most of cognitive psychological research is based on humans. For instance the duration of short term memory and long term memory. Some species may have short term memory which is long till few hours. thus first this should be confirmed before we determine is episodic emory used or working memory as episodic memory is long term memory. There is a thin line between explicit and implicit memory which is further complicated by the lack of language use. Further Advances in biotechnology can tell is explicit memory being used or implicit, depending on the type of region used in the brain during testing. There are currently such barriers in research of episodic like memory in animals which leads to ambiguity and other explanations may be true.
This research tests the memory theories of levels of processing proposed by Craik and Lockhart (1972) and encoding specificity presented by Wiseman and Tulving (1976). Craik and Lockhart (1972) assert that stimuli that are semantically related are encoded more deeply than stimuli that are related physically. Wiseman and Tulving (1976) state that encoded information must be retrieved in the same way in which it was encoded. These two theories come together in the current experiment where the subjects rate the relatedness of word pairs on either rhyming or categorization. Then the subjects complete a free recall or cued recall from the word list. It is hypothesized that the category encoded words will be easier to retrieve in both the cued and free recalls and that the congruently encoded and retrieved words (e.g., category encode and category recall) will be easier to retrieve. The results affirm the hypotheses resulting in a significant interaction between encoding and retrieval, and a significant difference between the means for the category and rhyming words.

Craik and Tulving did a series of experiments on the depth of processing model. They had participants use a series of processing methods to encode words at different levels; shallow, moderate, and deep. The subjects were shown a series of words and ask questions about the words that would provide a "yes" or "no" response. At the shallow level they were asked questions about whether or not the word was written in capital letters. At the moderate level of processing, the subject was asked questions as to whether or not two words rhymed. Finally, the subjects were asked about words in sentences and whether or not they fit. This was the deep level of processing. After participants had completed the task they were then given a surprise recognition test with the words that they were just asked questions on (target words) and then words that they have never seen before (distraction words). The results of the experiment showed that people remembered the words better that were at deeper level of processing (Craik and Tulving 1975).

In this experiment we replicated a study done by Bransford and Johnson (1972). They conducted research on memory using schemas. All human beings possess categorical rules or scripts that they use to interpret the world. New information is processed according to how it fits into these rules, called schemas. Bransford and Johnson did research on memory for text passages that had been well comprehended or poorly comprehended. Their major finding was that memory was superior for passages that were made easy to comprehend. For our experiment we used two different groups of students. We gave them different titles and read them a passage with the intentions of finding out how many ideas they were able to recall. Since our first experiment found no significant difference, we conducted a second experiment except this time we gave the title either before or after the passage was read. We found no significant difference between the title types, but we did find a significant difference between before and after. We also found a significant title type x presentation interaction. We then performed a third experiment involving showing objects before and after the passage was read. There we did encountersome significant findings. The importance and lack of findings is discussed and we also discuss suggestions for future studies, and how to improve our results.

In this experiment, the effect of chunking on memory retrieval will be explored. The aim of this research is to see how chunking in well-known terms would affect the way we encode information into our memory. The experiment investigated the effects of chunking on the capacity of STM (shot term memory) on cognition. The cognitive process involves the encoding, storage, and recall of information. Through this reason we can store newly acquired information and use prior knowledge.This experiment will be a based on research made by George Miller (1956). Miller demonstrated his theory in Short term store being limited by space, however, allows increase in capacity with smart methods such as chunking. He further looked upon studies relevant to chunking. By using Claude Shannon’s mathematical theory of information being measurable, Miller’s calculations showed that on average people could remember a string of plus or minus seven figures (letters or numbers) and only four or five words. Chunking is a technique where numbers and letters are grouped into units, more effective when meaningful.
According to Sweller (1998) human information processing has three parts: sensory memory, working memory and long-term memory. Information from the sensory memory passes into the working memory where it is processed or forgotten, the working memory can retain limited chunks of information at one time (Sweller, Merrienboer & Paas, 1998). Sweller et al. (1998) state that once the brain processes the information in the working memory it is then categorized and passed into the long-term memory whereby the knowledge is constructed into schemas. Consequently, the schemas organize the processed information which is dependent on how we use it. The more we use schemas the better the results are when trying to recall that piece of information (Sweller, Merriënboer & Paas,
