Abstract

Sposobnost mirisa da pobude autobiografska sjećanja kod osobe dobro je dokumentiran i poznat fenomen. Međutim, malo je istraživanja koja se bave odnosom njušnih podražaja i drugih vrsta pamćenja te mehanizme u podlozi tih odnosa treba bolje istražiti. Cilj ovog rada je bio pridonijeti razumijevanju odnosa između njušnih informacija i semantičkog pamćenja te provjeriti ovisi li taj odnos o rodu. Korišten je složen eksperimentalni nacrt s dvije nezavisne varijable: rod i prisutnost njušnih podražaja. Istraživanje smo proveli na uzorku učenika 2. i 3. razreda gimnazije (N = 60), koji su bili ravnomjerno podijeljeni u tri eksperimentalne grupe (prva grupa bila je bez prisutnosti njušnih podražaja; druga grupa imala je njušni podražaj prisutan i tijekom učenja i tijekom dosjećanja; treća grupa imala je njušni podražaj prisutan prilikom učenja, ali ne i prilikom dosjećanja), s jednakom rodnom zastupljenošću u svim grupama. Sudionici su učili kratak novinski članak nakon kojeg su rješavali distraktorske zadatke te su na kraju rješavali zadatak dosjećanja. U istraživanju su korištene dvije zavisne varijable: ukupni rezultat koji je uključivao i bodove dane za bliske sinonime (kvantiteta dosjećanja) i rezultat ostvaren zbrajanjem samo cjelovito reproduciranih cjelina (kvaliteta dosjećanja). Rezultati su pokazali neznačajan glavni efekt njušnih podražaja na dosjećanje i neznačajnu interakciju roda i njušnih podražaja. Utvrđen je značajan glavni efekt roda, no samo za zavisnu varijablu kvalitete dosjećanja.

Abstract (english)

The ability of smells to awake autobiographical memories in people is a well known and documented phenomenon. However, research on the relationship between olfactory stimuli and other types of memory are few and the mechanisms involved need to be better explored. The aim of this study was to add to the understanding of the relationship between olfactory information and semantic memory and to examine that relationship in regard to gender. Factorial design with two independent variables was used: gender and presence of olfactory stimuli. The sample consisted of high school students in second and third class (N = 60) that were equally distributed in three experimental groups with regard to gender (in the first group there was no olfactory stimuli; in the second group olfactory stimuli were present during both learning and recall; the third group had olfactory stimuli present during learning, but not during recall). The participants learned a short newspaper article after which they were solving distractor tasks, and at the end a recall task. Two dependent variables were the total score, which also included points given for close synonyms (recall quantity), and perfectly reproduced units (recall quality).The results have shown an insignificant main effect of olfactory stimuli on recall and an insignificant interaction between gender and olfactory stimuli. Main effect of gender was significant for the dependent variable recall quality.
