Journal article (peer-reviewed)abstract
- Few studies have investigated long-term odor recognition memory, although some early observations suggested that the forgetting rate of olfactory representations is slower than for other sensory modalities. This study investigated recognition memory across 64 days for high and low familiar odors and faces. Memory was assessed in 83 young participants at 4 occasions; immediate, 4, 16, and 64 days after encoding. The results indicated significant forgetting for odors and faces across the 64 days. The forgetting functions for the 2 modalities were not fundamentally different. Moreover, high familiar odors and faces were better remembered than low familiar ones, indicating an important role of semantic knowledge on recognition proficiency for both modalities. Although odor recognition was significantly better than chance at the 64 days testing, memory for the low familiar odors was relatively poor. Also, the results indicated that odor identification consistency across sessions, irrespective of accuracy, was positively related to successful recognition.

Autobiographical Memory : Depending on sensory retrieval cue and gender
- 2019
-
Doctoral thesis (other academic/artistic)abstract
- In my thesis I raised two questions: Does autobiographical memory differ i) depending on the sensory retrieval cue (Study I and II)? and ii) depending on gender (Study III)?Concerning retrieval cues, three unimodal cues (i.e., photographs, naturalistic sounds and odors) and one multimodal cue (i.e., the three unimodal cues presented simultaneously) were used to evoke autobiographical memories. The results demonstrated that the memories differed depending on retrieval cue. In particular, the olfactory-cued memories differed in semantic content and were from an earlier age in contrast to the other modalities. The visually and auditory-evoked memories differed less than expected in their semantic content and age distribution in relation to the multimodal condition. The multimodally cued memories could be described as being a combination of the three unimodalities, as illustrated by the semantic content and age distribution, though they were more similar to the visually and auditory-cued memories than to the olfactory-cued memories. One possible explanation for these results could be that we attend more to visual and auditory perceptions than to olfactory.With regard to gender, previous research has found gender differences in the manifest content (i.e., the actual words used) of autobiographical memories. However, to my knowledge none has investigated gender differences in the latent content (i.e., the underlying meaning in the expressed words). The results indicated that there was no difference between the genders in the manifest content. However, the females latently described their memories in more communal terms than males did, which supports the assumption that females are more communally oriented than are males.

Gender differences in autobiographical memory : females latently express communality more than do males

Journal article (peer-reviewed)abstract
- Gender differences have been found in several aspects of autobiographical memory (i.e. personally experienced events). For example, previous studies have shown that females’ autobiographical memories contain more communal and emotional expressions than do males. However, an important question concerns whether these differences can be observed both in the manifest content (i.e. what is actually said) and in the latent content (i.e. the underlying meaning of what is said). In the present exploratory study, we extended the current knowledge concerning gender differences in autobiographical memory by investigating the manifestly expressed words, as well as the latently expressed words in autobiographical memory descriptions. We observed an overall gender difference in the latent content of the autobiographical memories. Furthermore, females latently described their memories in more communal terms than males did. No other gender differences were found. Our results indicate that females’ autobiographical memories are more communally oriented than male's.
