  2. 11. FEAR - A process influenced by concurrent processing demands

    Author : Anna Bjärtå; Örjan Sundin; Elaine Fox; Mittuniversitetet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Attention; Fear; Performance; Processing resources;

    Abstract : Fear is a central aspect in mammalian evolution, prompting escape from and avoidance of threat and dangers. Therefore, it is reasonable to believe that we have a well developed system to detect dangers and quickly respond to them. READ MORE

  4. 12. Erasing Fear : Effect of Disrupting Fear Memory Reconsolidation on Central and Peripheral Nervous System Activity

    Author : Thomas Ågren; Mats Fredrikson; Tomas Furmark; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Memory reconsolidation; fear conditioning; serotonin; dopamine; polymorphism; gene; exposure therapy; fMRI; amygdala;

    Abstract : Fear memories, here defined as learned associations between a stimulus and a physiological fear reaction, are formed through fear conditioning. In animals, fear memories, present in the lateral amygdala, undergo reconsolidation after recall. READ MORE

  5. 13. Deflating selection : On the interpretation and application of evolutionary theory

    Author : Björn Brunnander; Sören Häggqvist; Paul Needham; Denis Walsh; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; ambiguity; causal factor; drift; evolutionary theory; force; function; intentional psychology; interpretation; multiple realisation; natural selection; philosophical method; pre-theoretical influence; redundancy; Theoretical Philosophy; teoretisk filosofi;

    Abstract : Although the theory of evolution is well-established it nevertheless presents us with a few unresolved matters of interpretation. One key task is to get clear about what exactly one should take the term 'natural selection' to denote. READ MORE

  6. 14. Mind in Motion: The utilization of noise in the cognitive process

    Author : Robert Pallbo; Data Vetenskap; []
    Keywords : HUMANIORA; HUMANITIES; AI; image processing; spontaneous activity; motion detection; knowledge acquisition; homunculus; evolutionary epistemology; evolution; cognition; noise; neural networks; Psychology; Psykologi;

    Abstract : The brain is not silent. Even in the absence of stimuli are the neurons activated every now and then in what is called "spontaneous" or "background activity" which provides a noisy background to the operation of the brain. This work shows how this noise can be utilized in the cognitive process. READ MORE

  7. 15. Predator psychology and mimicry evolution - a theoretical analysis

    Author : Alexandra Balogh; Olof Leimar; Michael Speed; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Müllerian mimicry; two-step evolution; gradual evolution; mutualism; predator psychology; Ethology and behavioural ecology; Etologi och beteendeekologi; etologi; Ethology;

    Abstract : The evolution of Müllerian mimicry depends on many factors, among which predator psychology is the most important one. Predator avoidance learning, generalization and discrimination are primary selective agents during the evolutionary process. READ MORE
