Influence of Dual Activity on Ram Recall Performance

The capability to multi-task proves to be always a necessary component of everyday life when considering the multiple roles that must perform efficiently in today's society. With many individuals routinely participating themselves in responsibilities that needs attention, it becomes circumspect for individuals to employ various ways of achieve reliable results. When contemplating the large amounts of stimuli that are being prepared during multi-tasking, having a higher capacity to multi-task could confirm advantageous. The concern is that these individuals may be limited in the beginning in overall ability to multi-task. The purpose of this test is to ascertain if dual-tasking influences memory performance. Men and female college students in a Psychology course at the School of Tx at Arlington (N=19) performed within an experiment that required these to memorize a set of words while in two conditions. The first condition (control) consisted of no activity performance when offered words. The next condition (experimental) consisted of performing sudoko while being presented with words. An impact was observed in memory performance for members between the two conditions. In addition deficits in performance were observed for participants which were placed in the dual task group in comparison with the control group.

Reading a cookbook while planning a meal, driving a vehicle your vehicle while texting, hoping to study while listening to the radio--multitasking can be an ability that lots of make an effort to perform. However, the capability to multitask is often difficult and sometimes impossible. Due to the fact many responsibilities can go unfinished, this can become quite irritating when an individual endeavors to do a couple of things at once. The need for studies evaluating the influences on multi-tasking action is necessary, if there is to be understanding to the actual factors that are participating. When considering past research many parameters have been investigated to ascertain possible factors of affect.

Over the years research affecting multi-tasking has suggested many ideas as to the predictors of performance in this field. Konig, Buhner, & Murling (2005), recommended that working storage area, fluid intellect, and attention are important predictors of multitasking performance. Although the previous research has investigated polychronicity and extraversion affects, no relation was found. Further, Konig et al. reported that out of the assumed predictors researched, "working recollection yielded the highest correlation". Additionally other studies (Buhner, Konig, & Krumm) have implicated that the rate and error found in multitasking may be attributed to aspects of working memory. Within their experiment the research workers stated to obtain implemented "a newly developed and well elaborated multidimensional model of working memory". The dimensions known in the test were, storage area in the context of control, coordination, and supervision. Buhner et al. also incorporate the constructs of attention and reasoning to their style of working memory for the purpose of determining other possible influences. They state "if attention and reasoning are disregarded when analyzing the predictive power of working storage area, then the model is underspecified" (pg 256).

Considering that many occupations require the capability to perform multiple responsibilities quickly and simultaneously, it is no real surprise that many employers have become more critical of potential individuals multitasking skills when employing employees. Person needs not only the ability of velocity in multitasking, but precision becomes an additional aspect that employers look for. Third, reasoning, Buhner et al. stated that "the goal for their study was to explore how specific differences in both of these areas of multitasking performance-speed and error-can be expected by other constructs, in particular working memory dimensions". Their results indicated that the constructs and measurements examined in their model became determinants in the predicting of multitasking speed and errors. If found to be valid, these results may lead to far better strategies that would increase creation and efficiency at work.

Acknowledging that cognitive constructs and abilities required for productive multitasking performance are not yet conclusive, the above mentioned research tests have at least increased our knowledge for some of the possible factors involved with multitasking, although no conclusive results has yet been proposed. The nervous about several theories is the fact that working memory space has been proposed to have limited capacity (Miller, 1956). Miller's research has determined that the capacity of short term memory is bound to plus or minus seven items of information. When contemplating the large amounts of stimuli that are being processed during multi-tasking, this may lead to the conclusions that results of people examined should perform quite similar. The issue lies in that this hardly shows to be the case. Stressing the constraints within current research a far more thorough procedure is then needed that regularly predicts the significance of possible influences involved. Utilizing and growing on previous ideas this research proposes that working memory can play a role in process efficiency and if deficits happen in working recollection during multitasking, then results could represent in real world applications considering multitasking works a sizable role in many occupations and everyday routine tasks. Interpreting the previous research discussed, the existing research hypothesizes the following:

Ho: It is expected that phrase recall on recollection performance test will not be affected by dual tasking.

H1: It is expected that term recall on recollection performance test will be influenced by dual tasking.



The study individuals included 20 undergraduate students from a cognitive psychology course at the University of Texas at Arlington. Participants consisted of 2 male and 18 feminine students ranging in time from 20 to 34 (M = 24. 9). Participants were randomly given to the single task (n = 10) or dual process condition (n = 10). The experimenters made every work to maintain the very best level of moral standards established by UTA's Institutional Review Board (IRB).


The current analysis employed a self-survey comprising questions regarding demographic information, including age group and gender. Microsoft Office Electric power Point Audience 2007 was used for the music recording and sound presentation of words. Words used through the presentation were arbitrarily chosen from the Kent-Rosanoff Word-Association List (Kent & Rosnaoff, 1910). A standard Sudoku puzzle, classified as effortless on a difficulty level that included easy, challenging, and difficult (http://pdfpad. com/sudoku/ ), was also used. Participants were provided with pencils and paper during administered duties. A stopwatch was used for the word recall testing phase.


Data was gathered from a cognitive processes laboratory in the springtime semester of 2010 on the University of Tx at Arlington. Before beginning the experiment members were asked to complete a demographic study and to hint an informed consent form.

After the participants were randomly split into the experimental (dual activity) and control (solitary task) communities, the experimental group was instructed to leave the area. Participants were up to date that they might be presented with an audio saving of words given at 4 second intervals. They were also instructed that immediately following the presentation they would be asked to remember all the words they could remember from the list. The ram phase contains a 1 tiny demonstration of 15 words adopted immediately by the assessment phase. In the testing phase members received 45 secs to recall in some recoverable format as many words from the list as is feasible. The single activity group was then debriefed, thanked for their time, and instructed to leave the room.

The dual job group was then helped bring in to the room. These were given a Sudoku puzzle and the same instructions for the music part of the experiment; however, they were instructed that they might be assessed on their performance of both the memory process and their capability to complete the puzzle. The storage area phase was similar to the solitary task group apart from the extra job. The Sudoku puzzle had not been evaluated but used as a distraction for the dual job. The testing phase was the same; members received 45 a few moments to recall on paper as much words from the list as is possible. The dual activity group was then debriefed of the real purpose of the study and thanked because of their time.


On the question of whether divided attention affects memory performance imply number of words recalled were analyzed for both conditions. The prediction was that there would be a significant decline in the performance of the divided attention group. The effects of divided attention were analyzed using an unbiased sample one tail t-test. Word recall for the divided attention group (M = 4. 889, SD = 1. 453) was found to be significantly less than the control group (M = 8. 900, SD = 1. 370), t(17) = -6. 192, p <. 001.


The focus of this study is to examine the influences of your dual job on storage area performance. It had been predicted by the studies that during the performance of a dual task, individuals' performance would be damaged. The results for this study do support this hypothesis. Furthermore deficits in performance were witnessed for participants that were located in the dual job group in comparison with the control group. Studying the data and relating it to past research, the analysts have determined that these deficits could be influenced by the limited capacity that working ram is considered to obtain. As discussed prior, prior research (Miller, 1956) suggest that task requiring similar cognitive processes can overlap lowering the available resources needed to perform each process efficiently. Using the participants using the available resources, those in the control group performed better when contemplating cognitive demands for their task do not have to be distributed as those in the dual process condition. As expected, deficits took place if the members' resources were taxed as observed in the experimental group.

Although evaluation of the data performed support the hypothesis, there's a matter for the generalization of the results to the overall human population. The participants employed in this particular study were all school student (Mindset Majors) and the relative size of the test group may well not be enough to be representative for the population. Furthermore only two test organizations were initiated because of this experiment. A far more feasible application of this study would be to implement multiple numerous groupings in each condition to produce more valid results. Replicating this analysis, researchers could also consider implementing different kinds of task to be able to examine the dissimilarities in cognitive resources that applied during specific activity.

In summary, the current research reflects the theory that there surely is yet an obvious answer to the influences of dual tasking on storage area. Although this specific study does provide proof recollection performance being damaged when a person engages them self cognitively with multiple roles, there's a peculiar aspect when contemplating that some participants outperformed others in the dual task condition. Could this observation be the consequence of some individuals having the ability to disperse their available resources more efficiently or will this suggest differences in working recollection capacities? Considering that we are in a diverse and demanding world, our potential to multitask is set to be a necessary element for survival. Even more so it becomes discouraging sensing that constraints in multi-tasking could be credited to available cognitive resources with some individuals having more than others.
