- Abstract
- A growing number of studies report relations between memory and smell. The present study aimed to identify differential effects of same and different smells on word learning and recognition memory, in addition to investigate the difference between pleasant and unpleasant smells. An old / new recognition task was used as a memory test, whereby participants (N = 32) studied 20 words in the first phase of the test and then in the second phase were presented with the same 20 words for identification intermixed with 20 new-words. Over 4 counterbalanced conditions, either the same (i.e., vanilla, vanilla) or different (i.e., vanilla, pepper) smells were sniffed in the first and second phases of the recognition task. The experiment failed to... (More)

The experiment failed to reveal any statistically significant differences between the different conditions. Neither the hypothesis that when the same smells are sniffed memory performance would be improved, or the hypothesis that pleasant smells would benefit memory performance, were statistically supported on the basis of conventional levels of statistically significant. In conclusion, it is argued that the hypotheses may be true, but the present experiment lacked sufficient sensitivity to reject the null hypotheses of no such effects. (Less)

- Ett växande antal studier rapporterar ett samband mellan minne och lukter. Den här studien ämnade identifiera effekter av samma och olika lukter vid inlärning och återkallande av minne samt undersöka skillnaden mellan goda och inte goda lukter. En så kallad old / new recognition task användes som minnestest där deltagarna (N = 32) tränade in 20 ord i testets första fas, för att sedan i en andra fas identifiera dessa ord bland en utökad serie på ytterligare 20 ord. Försöksdeltagarna fick samtidigt lukta på vaniljsocker och vitpeppar ur muggar. Fyra jämnt balanserade betingelser, antingen samma lukter (t.ex. vanilj, vanilj) eller olika lukter (t.ex. vanilj, peppar) användes som stimulus vid den första respektive den andra testfasen....

Fyra jämnt balanserade betingelser, antingen samma lukter (t.ex. vanilj, vanilj) eller olika lukter (t.ex. vanilj, peppar) användes som stimulus vid den första respektive den andra testfasen. Resultatet av experimentet visade inga statistiskt signifikanta skillnader mellan de olika betingelserna. Varken hypotesen att samma lukt vid inlärning och förhör ökar prestationen vid ett minnestest eller hypotesen, att en god lukt leder till förbättrad prestation på ett minnestest jämfört med en mindre god lukt, kunde därför bekräftas. Däremot visades en viss variation i medelvärden mellan samma och olika lukter, men ej tillräckligt stor för att ge ett signifikant resultat. (Less)
