Depth of Processing and the Self Reference Effect
There have been many experiments done on depth of processing and the self reference effect. The Depth of Processing model of memory maintains that how deep something is encoded into a person's memory depends on using certain types of processing. This relates to the self reference effect because it is believed that people have the tendency to remember something better when they can relate it to themselves. People who can personally relate to something have the tendency to embed it deeper into their memory.
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).
Although there was some criticisms about the above experiment, Craik and Tulving performed more experiments each time refining the D.O.P. model. There were thoughts that the structural tasks were easier and not as much time had to be spent on them therefore people did not have as long to look at those words and could not study them like the other tasks. Craik and Tulving then made the structural task take equally as long as the other tasks. The results remand the same as the previous experiments. Craik and Tulving also originally started with five tasks, but then narrowed it down to three to avoid a ceiling effect. The self-referent task was later added to model by Rogers.
Although correlation does not equal causation, we can conclude that similar cognitive processes, such as interference and automaticity, have influenced the results in our experiment. This can be expressed by the data and in identifying and saying aloud/reading a simple number compared to quantifying simple numbers. The cognitive load of reading familiar or smaller words is lower than that of counting, thus creating perchance a longer reaction time. In the experiment conducted in class as well as the one conducted by Stroop, the issue of divided attention may have been a great factor in interference or prolonged reaction time in the conditions. Psychological refractory period which states that the response to a second stimulus is slowed down by the first stimulus being processed; this can be a cause for the finding of increased reaction time when conflicting information is given. Attention may unconsciously be given to the less complex task, which is reading/identifying, and counting the main and more complex task may be interfered by the simpler stimulus. The expectation of having a longer reaction time when conducting the incongruent task was referenced back to the Stroop effect due to the similar implications of identifying and saying aloud the color presented in the print of the color descriptive word (Stroop,
...ffect. This theory suggests that recognizing and naming colors is not an “automatic process”. The attention need to be shifted from word to recognition of color; and there is hesitancy to respond; whereas, reading a word is habitual. The brain automatically understands the meaning and the phonetics of the word. The habituation of the reading task does not require controlled attention. Hence it is easier to read a word than to recognize the color of the word. More than theorizing on the phenomenon of Stroop effect, there is application value to this study. The experimental data and observations in the current study are very vital that it can be applied in many situations where the correctness is important than the speed. This information has the widest application in selection of individuals in occupations requiring instance data processing and correct responses.
“Too black for the white kids, too white for the black kids.” “Where do I fit in?” These are common question one may ask himself if he is struggling with double consciousness. Many people struggle with double consciousness every day without even realizing the effects it has on themselves or even the people around them. Double consciousness was discovered in 1903 by W.E.B. Du Bois which he referenced the internal conflict experienced by subordinated groups in an oppressive society. He relayed his message in his writing “The Souls of Black Folk”. Like stated before, double consciousness has many different effects on a person such as them trying to fit in, them having to feel like they have to pick a side (black side or white side), or eventually losing himself.
The Effects of Levels of Processing on Memory PB1: Identify the aim of the research and state the experimental/alternative hypothesis/es. (credited in the report mark scheme) To show how different levels of processing affects the memory. “People who process information deeply (i.e. semantic processing) tend to remember more than those who process information shallowly (i.e. visual processing). ” PB2: Explain why a directional or non-directional experimental/alternative hypothesis/es has been selected. (I mark) I have used a directional experimental hypothesis because past research, such as that by Craik and Tulving (1975) has proved this. PB3:
Over the years, memory have been researched and debated, however there are two theories that have explained extensively and are highly recognised by psychologist in the cognitive field of psychology and scientist alike, on how we process experiences and turn them into memories. These theories include the Atkinson and Shiffrin (1968) Multi-store Model of Memory and Baddeley and Hitch (1974) Phonological Loop Model of Memory. This essay aims to compare, contrast and evaluate these models of memory, with supporting evidence and empirical research.
The Extended Mind Hypothesis does exactly what it says on the tin. It is a theory suggesting that the human mind is not necessarily limited to a mental capacity. According to Clark and Chalmers the mind can extend to include information storage devices (such as computers, diaries, or even other peoples minds) to which we can have ready access, can rely on and trust as we would our own minds. These devices would be in a similar mode or state as the subconscious mind, that is; they would embody dispositional beliefs. This is known as active externalism.
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).
Dehaene provides many studies within the book to explain how the unconscious is capable of processing semantic information. In the 1970s Anthony Marcel produced a study in which participants were flashed the word red or blue under the threshold of consciousness, then asked to pick a corresponding color, even though the participant stated that he/she was not able to perceive any word being shown. The study showed that participants were able to choose a corresponding color one-twentieth of a second faster when the word flashed ahead of time was red or blue, instead of an unrelated word. Since the participant was better able to pick the color patch based on the congruent primed word, it can be suggested that the brain is able to unconsciously process
Similar studies were done to a different set of college students and they tended to have the same results. After giving as much detail about each memory, the students were interviewed about what they may have written done about what they had remembered. During the last part of the experiment, each of the students were debriefed and asked to guess which memory they believed was false.
The serial position effect has been studied extensively for many years. Researchers have designed a variety of different studies in order to analyze and explain both, the primacy and the recency effect. The primacy effect is the tendency for the first items presented in a series of words to be recalled more easily, or to be more influential than those presented at the end of the list. On the other end, there is also the recency effect. The recency effect is the tendency to recall the items located at the end of the list. Many studies have been designed to analyze how the primacy effect works and its accuracy. For instance, research compared the primacy and the recency effect (Jahnke, 1965). Forty-eight college students read lists of 6, 10, and 15 English words in a counterbalanced order. Twenty-four of the students were given instructions for the immediate serial recall of the list; while the other half of students were not aware that they would need to recall words from a list. Both groups received a total of 12 different lists. The words were read at a rate of one word per sec without any emphasis on specific word. In addition to that, the participants’ responses were recorded in an interval of 30 seconds. Results showed that the recency effect is stronger for free serial recall and for a longer interval than primacy effect (Jahnke, 1965). When instructions were given for a serial recall, primacy effects were stronger and recency effect weaker than when instructions were given for free recall. As the length of lists increased, the recency effect became stronger and more accurate.

Flowers would show a color word like “yellow” and “blue” on a colored background. There was a pause with a blank screen, then the subjects were shown a two different colors that were half and half on the page, like yellow or blue. The subjects then had to indicate which color word initially was presented to them. “He did not investigate the influence of this paradigm on normal Stroop interference, however, and his task differs from traditional tasks in having a delayed, binary response”
Question # 2: Identify similarities and differences among Theory X and Theory Y, the Pygmalion effect, and self-concept.
“Consciousness is defined as everything of which we are aware at any given time - our thoughts, feelings, sensations, and perceptions of the external environment. Physiological researchers have returned to the study of consciousness, in examining physiological rhythms, sleep, and altered states of consciousness (changes in awareness produced by sleep, meditation, hypnosis, and drugs)” (Wood, 2011, 169). There are five levels of consciousness; Conscious (sensing, perceiving, and choosing), Preconscious (memories that we can access), Unconscious ( memories that we can not access), Non-conscious ( bodily functions without sensation), and Subconscious ( “inner child,” self image formed in early childhood).
