1. 11. Food hoarding: Memory and social conditions - an evolutionary approach

   Författare :Ken Lundborg; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Djurekologi; Animal ecology; Corvidae; Paridae; dominance rank; memory; food hoarding; foraging; hippocampus; birds; behavioural ecology;

   Sammanfattning : Food hoarding is a widespread behavior among a large number of animals, and it exists in several different varieties, all of them used by the animals as a method of having a steady supply of food during periods of low food abundance such as the winter. This thesis concentrates mainly on two aspects of scatter food hoarding behavior, using small birds as study and model animals. LÄS MER

3. 12. Contours of Cognition

   Författare :Trond A. Tjøstheim; Kognitiv modellering; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; computational; cognitive; neuroscience; perception; memory; spatial cognition; trust; pupil dynamics; reflection; thinking; intelligence; reinforcement learning; foraging; allostasis; decision making;

   Sammanfattning : This thesis concerns the nature of cognition. It posits that cognitive processes primarily are means to maintain allostasis in organisms whose ecological niches require movement to approach food-resources and avoid predation. LÄS MER

   Sammanfattning : In recent years the number of connected devices and the demand for high data-rates have been significantly increased. This enormous growth is more pronounced by the introduction of the Internet of things (IoT) in which several devices are interconnected to exchange data for various applications like smart homes and smart cities.

5. 14. Föreställningar om den urbana världen : Identitetsaspekter i svensk stadsbild med exemplet Helsingborg 1903-1955

   Författare :Henrik Widmark; Hedvig Brander Jonsson; Ola Wetterberg; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Art history; Architecture; City planning; Heritage; Preservation; Spatial practices; Visual practices; Representations of Space; Urban culture; History; Memory; Modernity; Dominant urban identity; City space; Public art; Konstvetenskap; Gregor Paulsson; Helsingborg;

   Sammanfattning : This thesis examines the subject of dominant local identities and the construction of urban representations in Sweden 1903-1955, as articulated in the city Helsingborg. The main focus falls on architecture, city planning and visual practices as means of establishing an urban identity. LÄS MER

7. 15. Tracking the Mind's Eye : Eye movements during mental imagery and memory retrieval

   Författare :Roger Johansson; Kognitionsvetenskap; []
   Nyckelord :HUMANIORA; HUMANITIES; Mental Imagery; Eye Movements; Eye-tracking; Encoding; Recall; Memory Retrieval; Episodic Memory;

   Sammanfattning : This thesis investigates the relationship between eye movements, mental imagery and memory retrieval in four studies based on eye-tracking experiments. The first study is an investigation of eye movements during mental imagery elicited both visually and verbally. LÄS MER
