PLEASE, TURN THAT CELL PHONE OFF! : A quantitative study regarding the effect of cell phone noise on memory retention in classroom environment (English)
Abstract [sv]

I den föreliggande studien undersöktes mobilljudens effekt på minnesbehållning i klassrumsmiljö. I Studien undersöktes även vilken teori – unitary teorin eller duplex-mekanism teorin – som lämpligast förklarade mobilljudens eventuella effekter på kognitiva mekanismer. Metoden bestod i att deltagarna tittade på en kort dokumentär och därefter utförde ett minnestest, som berörde dokumentärens innehåll. Experimentgruppen fick titta på dokumentären, samtidigt som ringsignaler och aviseringsljud spelades upp under fyra perioder i dokumentären, medan kontrollgruppen inte utsattes FÖR buller. Deltagarnas hågkomst av innehållet av dessa fyra perioder prövades genom testfrågor. 27 försökspersoner deltog i experimentet, varav 11 personer var i kontrollgruppen och resten i experimentgruppen. Resultatet visade inte någon effekt av mobilljud på deltagarnas minnesbehållning. Resultatet stödjer dock duplex-mekanism teorin, vilket betyder att unitary teorin inte stöds i den föreliggande studien. Däremot, försvårar metodologiska brister och lågt antal deltagare tolkningen av resultatet. Förslag för framtida forskning inbegriper metodologiska förbättringar och undersökningsområden.

Abstract [en]

The aim of the present study was to investigate the effect of cell phone noise on memory retention in classroom environment. A second purpose of the study was to determine which theory – unitary account or duplex-mechanism account – would best explain the effect of cell phone noise on cognitive mechanisms. The method required the participants to watch a short documentary and afterwards complete a memory test, consisting of gist questions. The experiment group was simultaneously being exposed to ringtones and text message signals of a cell phone during four episodes of the documentary, whereas the control group was not exposed to noise. The participants’ memory retention of the content of those four episodes was tested via so called test items. 27 participants participated in the experiment, where 11 of them were in the control group and the rest in the experiment group. The results failed to find an effect of cell phone noise on participants’ memory retention. The results support the duplex-mechanism account, which means that the unitary account is not supported in the present study. However, methodological flaws and the small sample complicate the interpretation of the results. Recommendations for future research involve methodological improvements and research areas.
