Music and no music condition Essay

The expenditure of music seems to be a steady-going way of operationalising the IV as many people do learn to the sound of music so at that placefore the difference between the music and no music break should be marked. Also, getting the role players to write down the words is a good way of measuring the DV as it means it is easy to collect and contemplate the data.The subscribe to itself was sooner simple and it seemed to measure what effects music has on attainment. The independent variable was manipulated in such a way that it was tough for there to be anyway the results could submit been affected significantly. Also because the bill method was very simple there isnt a run a risk that the results could be interpreted in the wrong way.As the study was a research lab experiment it doesnt sop up as high stiffness as a field experiment. Although the participants were not in a funny environment, the situation that they knew they were being analyze may lower the ecolog ic rigourousness of the study.Leading on from the fact that the study might throw pernicious ecological validity, there is also the problem of the study having bad participant reactivity. Seeing as they have they are being studied and they know they have to learn the list of words given to them, they may demonstrate much harder than they norm in ally would in their everyday life. There is the factor of well-disposed desirability and how some participants may deliberately try to recall few words.Improving ValidityAlthough it would be very surd and expensive it could be possible to take the study outside the laboratory to increment the ecological validity of the study. You could monitor the participants while they are learning for something at firm and while they are playing their own music in their agencys. They could past be tested unknowingly at school by 1 of their reachers.However, even if these exchanges were made, the results would probably still stay the same. It has been proved before by numerous studies accepte by assorted scientists that music does help when move to learn. This is why students are encouraged to listen to wordless music when revise for exams.These changes would also help improve participant reactivity if they are studied in a familiar environment. It would give them a sense of trade protection and the need to look cool is not needed anymore and there is no extra pressure put on them to learn because they dont have the feeling they are being examined.So, these changes could actually change the results slightly if only with a few participants. It might be implant that there is higher recall in both cracks though moreover the difference may still stay the same.ReliabilityThe study is very easy to replicate as there is many references to other studies alike to it. Also because the study is quite simple in itself and very brassy to do there are very rarely any problems in recreating it for different purposes.One poss ible confounding variable was introduced by the fact that there were four researchers in the room at the time of the study and they all knew the hypotheses. They may have tried give the participants help in recalling the words by giving hints and clues so that the results were more conclusive. This may have led to unreliable comparisons between shapes.As the study was a laboratory experiment it meant the researchers had good control over the study. The words that were chosen were all unambiguous so the participants would not have interpreted them in different ways. Also the test had been severely standardised. The words were shown on an over item projector so they were all looking at the same thing when learning was taking place. Also the testing was completed in the same room and at the same time of day for each condition so the participants were not feeling more tired in one condition than the other.Improving reliablenessThe only possible way to improve reliability was to keep r esearcher contact to a minimum or have a person in the room that was unaware of the hypothesis so they couldnt alter the study in any way. This would be difficult though because once they are in the room it does become quite obvious what the study is about.This could be controlled for by using an outside noncombatant to be the one person giving the participants instructions on what they have to do. There could be one person chosen for each condition so that they dont guess what the study is about.Even if these changes did increase the reliability of the study the only difference they might make to the results is to step-down the differences found between the two conditions.
