2. 1. Individual Differences in Multitasking : Support for Spatiotemporal Offloading

   Author : Ivo Todorov; Timo Mäntylä; Fredrik Jönsson; Patrik Sörqvist; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; multitasking; cognitive offloading; cognitive functions; individual differences; executive functions; spatial ability; sex differences; Psychology; psykologi;

   Abstract : In both the private and work spheres, multitasking among three or more activities has become and is continuing to evolve as a pervasive element of everyday life, and recent technological advances only seem to be exacerbating the process. Despite attempts to understand the mental processes that let humans successfully multitask, little is known about the functional cognitive level at which these mental processes take place. READ MORE

4. 2. The aging brain and changes in cognitive performance : Findings from morphometry and quantitative susceptibility mapping of iron

   Author : Ninni Persson; Håkan Fischser; Kristine B. Walhovd; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; brain aging; volumes; ndividual differences; QSM; cognitive aging; iron; episodic memory; fluid-; crystalized abilities; sex differences; gender differences; Psychology; psykologi;

   Abstract : Brain aging is a heterogeneous phenomenon, and this thesis illustrates how the course of aging can vary within individuals over time and between individuals as a function of age, sex, and genetic variability. We used two contrasts from magnetic resonance imaging (MRI), namely spin-lattice T1-weighted imaging, and quantitative susceptibility mapping (QSM) from gradient-echo images, to picture the aging brain, by means of morphometric measures and brain-iron concentrations.

6. 4. The genetics of schizophrenia : sex, drugs, and cognition

   Author : Elise Koch; Karolina Kauppi; Lars Nyberg; Anders Lundquist; Alessandro Serretti; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; schizophrenia; genetics; cognition; sex differences; polygenic risk; fMRI; network medicine; drug repurposing; precision medicine;

   Abstract : Cognitive impairment constitutes an important predictor of general functional outcomes in schizophrenia. Polygenic risk for schizophrenia has been linked to cognitive ability as well as brain activation during cognitive processing. READ MORE

7. 5. 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.
