2. 1. Olfactory Cognition : The Case of Olfactory Imagery

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

   Abstract : 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. READ MORE

4. 2. Olfactory Function : The Influence of Demographic, Cognitive, and Genetic Factors

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

   Abstract : 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. READ MORE

5. 3. The Role of Odor and Sensory Irritation in Human Chemical Sensitivity

   Author : Li Zheng; Birgitta Berglund; Staffan Hygge; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Odor and irritation detection; recognition; threshold; choice theory; intensity; chemical sensitivity; threshold; and sensitivity index.; Psychology; Psykologi; Psychology; psykologi;

   Abstract : The main objective of this thesis is to apply complimentary psychophysical theories and methods to investigate human perception of odor and sensory irritation of chemical compounds present in indoor air. Three psychophysical theories: Signal Detection Theory (SDT), Threshold Theory and Luce’s Choice Theory (CT) were applied to measure detection and recognition of odor and sensory irritation of two odorous irritants (pyridine and formaldehyde) by using the method of constant stimuli.

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

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

   Abstract : 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.
