2. 1. 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

4. 2. 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.

5. 3. Gas discrimination for mobile robots

   Author : Marco Trincavelli; Amy Loutfi; Silvia Coradeschi; Alcherio Martinoli; Örebro universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TECHNOLOGY; TEKNIKVETENSKAP; Information technology; Informationsteknik; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

   Abstract : The problem addressed in this thesis is discrimination of gases with an array of partially selective gas sensors. Metal oxide gas sensors are the most common gas sensing technology since they have, compared to other gas sensing technologies, a high sensitivity to the target compounds, a fast response time,they show a good stability of the response over time and they are commercially available.

6. 4. Learning and memory in moths - plasticity in behaviour and neurophysiology

   Author : Ruey-Jane Fan; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; proboscis extension reflex PER ; LTM; MTM; STM; memory; inter-trial-interval ITI ; inter-stimulus interval ISI ; US; CS; olfaction; Associative learning; classical conditioning; discrimination; the US pathway; Ecology; Ekologi; Animal physiology; Djurfysiologi;

   Abstract : The moth, Spodoptera littoralis, was demonstrated to be a new model system for studying mechanisms underlying odour conditioning. In the experiments a restrained moth was trained to learn an association between a conditioned stimulus (CS) and an unconditioned stimulus (US). READ MORE

7. 5. Auditory and Olfactory Abilities in Blind and Sighted Individuals : More Similarities than Differences

   Author : Stina Cornell Kärnekull; Maria Larsson; Mats E Nilsson; Johan Willander; Fredrik U Jönsson; Johannes Frasnelli; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; absolute threshold; audition; autobiographical memory; blindness; discrimination; episodic recognition; identification; imagery; judgments of learning; memory; metacognition; olfaction; onset age of blindness; reminiscence bump; sensory compensation; Psychology; psykologi;

   Abstract : Blind individuals face various challenges in everyday life because of the lack of visual input. However, since they need to rely on the non-visual senses for everyday tasks, for instance, when navigating the environment, the question has been raised as to whether perceptual and cognitive abilities in these senses may be enhanced.
