Psychology – Experiment on Stress

Introduction In this experiment we ar going to describe stress and prove how can a lengthen rendering to it make a negative impact on keeping. The r extirpateering of stress use in this experiment is difficulty star suffers that causes worry, excited tension or loss of concentration. The reason why this topic has been elect is because stress is a part of nowadays, hectic society and it has a genuinely noniceable effect on flocks fareance, in either work or daily behavior. The outcome of this experiment could be used in several fields, such as education to help subordinate the amount of stress students deal with, so their grades could be improved.The results could also be used to enhance and boost employers efficiency, in the workplace field. The opening is to test how short-term stressful situations can lead to memory dysfunction. The slide fastener hypothesis, on the different hand, is that stress has no impact on memory whatsoever. The club of this experiment i s to prove how stress produces memory issues. II. Design The nigh efficient and easiest way to carry out this experiment would be victimization repeated measures, use the aforementi integrityd(prenominal) sample of thespians in both sets of conditions, deceiving players to distract any internal rigourousness issue.Allowing a long time first step between conditions or changing the mentioned conditions would obviate participants from finding out the aim of the experiment, or biasing it. Single blind is the best method that can be used in this experiment, opposed to double-blind, which would be meaningless, because if participants are told the aim they skill do better than they would do in a normal life situation, and the study would lose its reliability.Since its a short-term establish experiment and the same sample of participants is used for both conditions, the experimental base would perform a series of memory-ch exclusivelyenging activities, and later on, the control a ggroup would perform the same tasks but under the influence of some source of stress, in this case, loud music. on that point are no ethical concerns involved because no participant would progress with any kind of stress or anger, and they wouldnt be exposed to loud music for a long time. They would also be debriefed at the end of the study.The Independent Variable (IV) is the amount of stress authorized by any mean, and the Dependent Variable (DV) is memory performance. Other variables that sh every last(predicate) be identified, since they are thought to make water an impact on the results are the following(a) previous level of stress of participants, temperature of the way where the experiment is being held, room walls color, participants previous fatigue or mood, amongst separates, which could be advantageously avoided by performing yoga classes and controlling the room were the experiment is being carried out. III. ParticipantsSince the nates population is people livin g in Spain from the age of 16 to people aged 66, both male and female, it includes a very large government issue of people in which the outcomes of this study are going to be focus on, and therefore, a huge target population to choose from in order to get participants for the study. Therefore, the best sampling technique that could be used would be quota sampling, as it allows the researcher to split the target population up into non-homogeneous sub-groups, which in this case would solely be age and gender, because no other variables can affect/bias the outcomes of this experiment.Then, from this preset sub-groups, the researcher would deliberately peck at out how many people is require and what characteristics this people must have. There would be 5 sub-groups based on age and gender ( to each one group ranging 10 years), each group adding up the total number of 25 people (5 per group ). Participants would be asked for consent after using them as the sample. IV. Materials Mat erials needed for this experiment are basically those involving any lab-related experiment.The primary materials would be a laboratory room or a classroom, equipped with tables, desks and chairs, as well as a board. Another room would be needed in order to perform the relax therapy sessions that would be useful for the experiment, so all types of equipment related to yoga is needed, such as mats, light weights, etc. The other type of material that is used is questionnaires on stress participants may have before performing any activity, a list of lyric for participants to hit the books, and a set of speakers, which will be the actual source of stress.V. Procedures * Gather participants in a room and have them do a stress questionnaire to debate what is their current level of stress. * With the results of such questionnaires split participants up into two groups, one including the more stressed people, and the other group the remaining people, participants should remain deceived u ntil the end of the experiment. * Have participants from both groups take yoga classes (or any comparable activity with the same purpose) so their level of stress is reduced and partially equal to one another.These sessions should not last for longer than 30 minutes. * This being done, have a brief group interview with them to see whether the relaxing activity was right-hand and useful, if so, carry on to next step if not, record the participants name in order to use this variables as a benefit when evaluating the results. * Make participants memorize a list of 10 words without any external stimuli such as noise or visual distraction, being given no longer than 10 minutes. Evaluate the capacity of the participants to memorize such words by giving them a test where they have to write bulge out the maximum number of words they can remember. * Afterwards, make participants wait for 15 minutes in a room with a source of stress, in this case, noise coming from speakers, similar to the one produced by whistles. Then, give each participant the second condition, another list of 10 words with similar spelling and same grammar category, but still applying the source of stress.However, participants are not going to be told that researchers are empowering this source of stress. They are given 10 minutes. * Have them write out a quiz testing them on how many words they were able to memorize in this environment. * If any participant was showing any symptom of being stressed or not feeling good, make the participant take some yoga classes so they leave the experiment without any stress debrief participants so that the experiment meets all ethical requirements. VI. AnalysisThe obtained data is quantitative because it is taken from the memory tests performed throughout the experiment, and a good way in which it could be presented visually and effectively would be by using bar graphs, such as the following, filled in with the recorded data. This graph lets us see the relatio nship between participants in both conditions, and easily compare performances. If participants were interviewed after performing the tests, we would also have qualitative data that would make our results more reliable.An area that could be researched on after performing this experiment could be how a prolonged description to stress could affect memory, as a way of looking into contingent starters of psychological illnesses such as Alzheimer, etc. The outcomes of this experiment could be apply in a variety of real life situations because stress is at an increasing rate in our modern societies, and studying how it energy affect peoples life is necessary. With such results, we could discuss how stress may slowly be deteriorating an individuals cognitive capacities, such as memory, or completely disprove our initial hypothesis.The experiment was carried out with the or so possible accuracy and passivity from the researcher in order to avoid any form of researcher bias. Participant s were not told the aim of the study or the hypothesis they were deceived to exclude participants bias, such as exact characteristics or the screw-you effect. However, a potential problem that could suppose using the same sample of participants for both conditions is that the aim of the experiment could be make out and therefore, participants could somehow bias the study.Even though researchers tried to take all possible variables into account to reduce the possible effects on the results, some couldnt be controlled, like the mood of participants or their previous exposition to stress throughout their lives, an important factor that can bias the study. On top of that, theres a lack of ecological validity because the study was performed in a lab and not in the participants natural environment where they are used to, so they might not act normally in a lab environment.
