A study about how stress and sleep affects the episodic memory and working memory (English)
Abstract [sv]

Många människor upplever stress och sömnsvårigheter till en viss grad vilket ger underlag för frågan: Hur påverkar dessa aspekter minnesfunktionerna? Studiens syfte handlar om att få en bredare förståelse för hur stress och sömn påverkar det episodiska minnet samt arbetsminnet. Studiens hypotes var att det episodiska minnet kommer att påverkas mer än arbetsminnet av stress och sömn. Forskning visar att stress och sömn har en stor påverkan på dessa minnesfunktioner. Studien använder sig av Perceived stress scale-10 och Karolinska sleep questionnaire som behandlar frågor om upplevda stress och sömnvanor och inkluderade 24 deltagare, 20 kvinnliga och 4 manliga studenter mellan 18-30 år på Örebro universitet. Data samlades även in med hjälp av två datoriserade minnestest som testar både det episodiska minnet och arbetsminnet. En experimentell design utfördes med resultaten som undersöktes med hjälp av fyra regressionsanalyser. Resultatet visade att det inte var statistiskt signifikant mellan det episodiska minnet och arbetsminnet gentemot stress och sömn. Alltså fanns det inga skillnader i minnesprestation för personer som var mer stressade och som sov sämre.

Abstract [en]

Many people experiences more or less stress and sleep deprivation to a certain extent which gives ground for the question: How do these aspects affect memory functions? The purpose of this study is therefore to gain a broader understanding of how stress and sleep affect the episodic memory and working memory. Research shows that stress and sleep have an affect on memory functions. The studys hypothesis was that the episodic memory will be affected more than the working memory by stress and sleep. The study is using Perceived stress scale-10 and Karolinska sleep questionnaire that entail questions about perceived stress and sleep, and included 24 participants, 20 female and 4 male students between the ages 18-30 years at Örebro university. The data was also collected using two database memory tests that examines both episodic memory and working memory. The study used an experimental design and obtained the results by performing four regression analysis. The results showed that there were no statistically significant differences between the episodic memory and workimg memory when it comes to stress and sleep. Thus, there were no differences between memory functions for people who were more stressed and who slept less.
