The Phonological Similarity Effect In Working Memory Psychology Essay

The Phonological Similarity Effect In Working Memory Psychology Essay A considerable amount of cognitive, behavioural research has been conducted on the working memory model and the role of the phonological loop and similarity effects on the serial recall paradigm. The purpose of this study was to extend the existing research available in support of the evidence for Baddeley and Hitch (1974) working memory model and the role of the phonological loop. A group of 18 undergraduate university psychology students were each subjected to two individual visual phonological tests to provide data on recall scores for a set of six similar and dissimilar letters. The data obtained was analysed separately before performing a using a two tailed paired related sample t-test. The results indicated that there was a statistically significant difference in scores obtained on recall of dissimilar and similar letters with higher scores being recorded on recall of dissimilar letters. Introduction The concept of a well-defined form of memory that is able to store information on a temporary basis whilst being utilised in the service of cognitive process is not new idea, but theories regarding the components that make up the short-term storage memory have evolved considerably during the last century (Gross, 2010; Myers, 2005). The proposal of the multi-store model (MSM) by Atkinsons and Shiffrin (1968) introduced the concept that short-term memory (STM) and long-term memory (LTM) had differing and distinct modes of storing information. This led to a considerable amount of research being conducted on how STM operated (Baddeley Hitch, 1974). Particular attention has been given to auditory and visuospatial input along with acoustically similar or dissimilar associations in the information being stored and the affect this may have on information recalled (Conrad, 1964; Wickelgren, 1965; Schulman, 1971; Atkinson Shiffrin, 1968). In Atkinson and Shiffrin (1968) model, the function of STM is said to provide a means of controlling and enhancing information before it makes it into long-term memory. This is done through rehearsal and coding strategies (Atkinson Shiffrin, 1968). In 1974 Baddeley and Hitch introduced their Working Memory (WM) model, a more dynamic system, as opposed to the more passive Atkinson and Shiffrin MSM (Baddeley Hitch, 1974). A definition of working memory can be stated as the collection of cognitive processes that allows information to be held temporarily in an accessible state, whilst in the service of some cognitive task (Baddeley, 2001). One of the important characteristics that differentiate the WM model from the Atkinson-Shiffrin (1968) MS model is the use of two distinct short-term memory buffers, the phonological loop and the visuospatial sketch pad and the argument that the independence of these buffers allow for a greater flexibility in memory storage (Baddeley Hitch, 1974; Baddeley, 1986) These short term memory buffers are two of the four components that make up the WM model (Baddeley, 1986). At the core is the central executive hub, which processes data and cognitive tasks, followed by the two memory subsystems; the visuospatial sketch pad, which processes information received in either visual or spatial form and the  phonological loop  the area within the WM that deals with language information in auditory or visual form. The final component is the episodic buffer, which was introduced 20 years after the model was first proposed, which links all the components of WM with long-term memory to enhance function (Baddeley Hitch, 1974; Baddeley, 1986; Baddeley, 2000) According Baddeley (1986) the phonological loop is comprised of two individual subcomponents; the phonological store, sometimes called the inner ear which holds auditorily presented verbal information and the articulatory control process (ACP), sometimes called the inner voice. Although limits to working memory are easily observed, ever since George Miller (1956) suggested people can recall approximately seven independent, items or chunks of information at a time, it has been more difficult to determine what specific cognitive faculties underlie these observed limits. It has been proposed in several studies (Conrad, 1964; Wickelgren, 1965) that observed limit recall depends upon details of the stimuli. For example, immediate memory retrieval for lists of serial presented verbal information is better when the lists that contain letters or words that are dissimilar as indicated in the experiments performed by Conrad (1959) and Wickelgren (1965). Consequently it is claimed there is a correlation between phonologically similar and dissimilar information input and memory span, specifically that the recall for dissimilar words or letters would be greater than that for the similar ones presented either auiditorable or viusally (Conrad, 1964; Wickelgren, 1965; Muller, Seymour, Kieras, Meyer, 2003; Eysneck Keane, 2010). The aim of this study was to examine the evidence for Baddel and Shiffrins (1974) WM model with the hypothises that there is a greater ability to recall letters that are dissimilar in nature to those that share common phonological similarities. Method Participants A total of 18 participants were recruited from within a group of undergraduate students, enrolled on the Swansea Metropolitan Universitys Psychology Joint Hons degree course. The participants ages ranged between 18 and 51 years, (M =26.89, R=33, SD=10.26). The participant group was comprised of six males whos ages ranged between 24 and 51 years, (M=35.5, R=27, SD=11.47) and 12 females whos ages ranged between 18 and 38 years, (M=22.58, R=20, SD=6.5). Materials The study materials consisted of two sets of six sequence cards one set for the similar letters and one for the dissimilar letters. The similar letter set comprised of the letters P, E, V, T, C and G with the dissimilar letter set comprising of the letters J, H, P, V, X and F. Each participant was given a blank recall sheet to record their answers with researcher using a score sheet to record their individual scores for each set of letters. Design This quantitative within-subject study sought to investigate the scores obtained between two variables using the paradigm of serial verbal recall. The independent variable (IV) being the similar and dissimilar letter sets used and the dependent variable (DV), being that of the recall scores of each participant. Scores were recorded between 0 and 6 for each of the tests; with only letters recalled in their correct positions being positively scored. All the data obtained was analysed using a two tailed paired related sample t-test within a SPSS package. Procedure Both the participants and researchers were all part of the undergraduate psychology course and due to the study being performed as part of their studies, no consent for was required to be signed. Participants were informed of the requirements for the study before each researcher selected two individuals from the participant pool in order to carry out the experiment, with each participant being tested individually and in isolation of the other. The experiment procedure was explained to each individual participant prior to testing, with a test run being conducted in order to assure full understanding was reached. Each set of six similar and dissimilar letters were presented to the participant separately, with each letter card being presented visually for 1 second, with a 2 second delay between the presentations of each new letter. After all of the six letters had been shown a 5 second delay was counted down by the researcher to allow for rehearsal, before the Recall Now card was shown. The participant then attempted to recall the letters shown in their correct sequence of display on the recall sheet. This was repeated for the next set of letters, with the same procedures being repeated. There was no preference of order for the similar or dissimilar letter sets to be shown first. The recall sheets were returned to the researcher who calculated their scores on each of the tests with all scores for each pair of participants collected by the researchers and collated together to give an overall data set of 36 sets of scores. Results Table 1: Comparison of recall scores between similar and dissimilar word sets Test Type Total Score Mean Participants (n) Std Deviation t df Sig. (2-tailed) Similar 130 3.66 36 1.66 2.38 35 0.23 Dissimilar 158 4.39 1.5 Table 1 shows the mean scores obtained for each of the conditions being tested; similar recall test (M=3.61, SD=1.66) and dissimilar recall test (M=4.39, SD=1.5). As the table indicates the participants scored higher on the dissimilar recall test by correctly recalling more letters in the right order of display than when tested on the similar letter set. Analysis of these results show a significant difference in the recall scores, t (35) = 2.38, p Discussion The results obtained in this study has shown that there is a significant difference in the number of letters recalled in correct sequence between similar and dissimilar sets of letters, with dissimilar letters being recalled better than phonologically similar acoustic sounding letters. These results support previous acoustic similarity recall effects in STM research (Conrad, 1964; Wickelgren, 1965; Muller, Seymour, Kieras, Meyer, 2003; Jones, Macken, Nicholls, 2004; Page, Cumming, Norris, Hitch, McNeil, 2006) and in turn support the concept of the phonological loop as proposed by Baddeley and Hitch (1974) WM model. The study also supports the findings of Smith, Wilson, and Reisberg (1995) in that the visual presentation of the letters sets were processed indirectly into the phonological store component of the phonological loop through the ACP allowing the participants to rehearse the letters observed acoustically using the inner voice. However, there are some concerns on the effects of phonological complexity related to word length including the number of syllables or phonemic length of the letters within words, which suggests that the word length effect in the serial recall task may be better explained by differences in linguistic and lexical properties of words (Jalbert, Neath, Bireta, Surprenant, 2011). It can be argued that studies of this nature have a low ecological value, as they dont represent the real world. Baddeley, Gathercole, Papagno (1998), claim that the function of the phonological loop has evolved in order to facilitate the learning of unique phonological forms of new words. They propose that this is its primary purpose, to store unfamiliar acoustic patterns while more permanent memory records are being fabricated. Despite this study supporting the hypothesis that there is a phonological effect that influences the ability to successfully recall more letters that are dissimilar in nature as opposed to those that share common phonological similarities, the use of the phonological loop in retaining sequences of familiar letters/words is, it is argued secondary to its primary function of learning language (Baddeley, Gathercole, Papagno, 1998).

The Influence of the Video Game in Children

The influence of the video game in children A. Violence. 1. Criminal behavior. 2. Disrespect for the authority and law. 3. Use and abuse of drugs and alcohol. B. Sex. Content 1. Abuse of toward women 2. Use of foul language and obscene behavior. 3. Category of the Video game C. Murders. 1. Killing people. 2. Killing animals. 3. Emotional effects. Conclusion. ?Did you know that in 1980 the video games transformed in a phenomenon that revolutionized around the world?Not mention has become a popular activity for people of all ages. As a result the video game is a multibillion dollar company and many children spend large amounts of time playing them and these create bad behavior and studies demonstrate that the children imitate the violence that they see. In the last years if has been shown an increase of rebel children due to the content in the video game they play such as violence, sex content and murders.The influence of the video games in the children has effects with the time. The c hildren who are exposed to violent spectacles can manage to be more aggressive and acquire a criminal behavior where they interact and answer with violence in his social environment. Also the video games transmit values that impact and impress the children and this creates rebellious behaviors and they do not respect the authorities and the laws.For this reason, they create bad vices as the abuse of the drugs and the alcohol to an early age. Another important point is the sexual content that these video games have. Many video games are related to sexual activities since they have not been designed for minors of 18-year-old. Often we see that these games insult and abuse to the woman and induce to the mistreatment and to the use of bad words and obscenities and as consequence is altered the normal and emotional ripeness of the children.Without mentioning that each video game in the part of behind of the box describes that we will find in the game and type of content already be of sex ual character. As an example of video game with sexual content are God of War and Assassin Creed. The murder to persons or animals is common in the video games. The only aim is to struggle and to obtain the major punctuation; nevertheless, this affects negatively the physical, mental, emotional development, and the social environment of the children.As result, it borders the time in order that the children and teenagers make other healthy and productive activities. Considering all these things is the responsibility of the parents to form his children in order that they are good persons for the society. Some children can involve so much in the video game and this creates an addiction and brings big consequences as lower qualifications, overweight, they happen less time with his families and finally they create aggressive behaviors.Also it is a duty of the parents in supervise his children and to know the content of the video games and of being informed what this being bought for his children since a market exists with thousands of video games and many of these have a bad content for his age. The most advisable thing is that the parents feel to playing with his children who interact with them, the parents need motivate his children in participate of other activities and the parents will have achieving a better communication and the safety of which his young minds are not corrupt with video games.
