  1. 1. Odor identification in aging and dementia : Influences of cognition and the ApoE gene

    Författare :Jonas Olofsson; Steven Nordin; Maria Larsson; Richard Doty; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Aging; olfaction; identification; dementia; Alzheimer; genetics; ApoE; population based; cognition; demographics; Psychology; Psykologi;

    Sammanfattning : Olfactory function is impaired in aging and dementia. The general aim of this thesis was to identify variables that predict olfactory function and dysfunction (assessed with an odor identification test) in middle-aged and elderly adults. LÄS MER

  3. 2. Olfactory Metacognition : A Metamemory Perspective on Odor Naming

    Författare :Fredrik Jönsson; Mats Olsson; Henrik Olsson; Egon P. Köster; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; odor identification; odor naming; metamemory; confidence; tip of the tongue experience; tip of the nose experience; feeling of knowing; Psykologi; Psychology; Psykologi;

    Sammanfattning : Although many aspects of odor naming have received attention during the years, the participants' own cognitions (metamemory) about their naming attempts have not. (i) We showed that feeling of knowing (FOK) judgments accompanying odor naming failures are predictive of later recognition (Study I) or retrieval (Study III) of the missing name, but to a lesser degree than equivalent judgments about names of persons.

  4. 3. Olfactory Cognition : The Case of Olfactory Imagery

    Författare :Artin Arshamian; Maria Larsson; Jane Plailly; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Olfactory imagery; sniffing; olfactory awareness; odor threshold; episodic odor memory; odor identification; odor evoked autobiographical memory; fMRI; Psychology; psykologi;

    Sammanfattning : The capacity to form olfactory images has received less attention than the formation of visual and auditory images. The evidence in favor of such ability is also inconsistent. This thesis explored some of the characteristics of olfactory imagery through three empirical studies. LÄS MER

  5. 4. The alluring nature of episodic odor memory : Sensory and cognitive correlates across age and sex

    Författare :Christina Blåvarg; Peter Juslin; Mats J. Olsson; Steven Nordin; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Olfaction; Age; Sex; Episodic odor memory; Odor identification; Recollective experience; Hedonic; Healthy; Adults; Psychology; Psykologi;

    Sammanfattning : Episodic memory for olfactory information is still relatively uncharted. The overall purpose of this thesis is to investigate the sensory and cognitive causes of the well-established age-related decline in olfactory episodic odor memory and of the age-independent sex difference in olfactory episodic memory.

  7. 5. Olfactory Function : The Influence of Demographic, Cognitive, and Genetic Factors

    Författare :Margareta Hedner; Maria Larsson; Lars-Göran Nilsson; Claire Murphy; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Olfaction; odor identification; odor threshold; odor discrimination; aging; gender; ApoE; BDNF; val66met; association study; population-based; Psychology; psykologi;

    Sammanfattning : Olfactory function is affected by demographic, cognitive, and genetic factors. In the present thesis, three empirical studies investigated individual differences in olfactory ability. Study I explored demographic and cognitive correlates in common olfactory tasks; odor detection, odor discrimination, and odor identification. LÄS MER
