2. 1. Virtual reality exposure therapy for spider phobia

   Author : Alexander Miloff; Per Carlbring; Lena (Lotta) Reuterskiöld; Nexhmedin Morina; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Specific phobia; spider phobia; spider; fear; anxiety; virtual reality; exposure therapy; automated; alliance; psychometric; factor analysis; virtual therapist; RCT; randomized; non-inferiority; clinical trial; dissemination; 12-month follow-up; Psychology; psykologi;

   Abstract : Exposure therapy for specific phobia involving systematic and repeated presentation of an aversive stimuli or situation is a highly effective treatment for reducing fear and anxiety. Dissemination of this evidence-based treatment has proved challenging, however, and for over 20 years an alternative method of delivery using virtual reality technology has been explored with positive results.

4. 2. Fearful attention : Investigating event-related potentials in spider phobia

   Author : Joakim Norberg; Stefan Wiens; Jonas Persson; Harald Schupp; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; attention; phobia; event-related potential; Psychology; psykologi;

   Abstract : Previous studies showed that emotional pictures capture attention. Further, this effect was decreased by manipulating spatial attention. In contrast, studies produced mixed findings for effects of perceptual load on attention to emotional pictures. Emotional pictures can be phobic or nonphobic. READ MORE

5. 3. The Amygdala, Fear and Reconsolidation : Neural and Behavioral Effects of Retrieval-Extinction in Fear Conditioning and Spider Phobia

   Author : Johannes Björkstrand; Mats Fredrikson; Emily Holmes; Uppsala universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Fear conditioning; phobia; memory reconsolidation; retrieval-extinction; exposure therapy; amygdala; fMRI; Psychology; Psykologi;

   Abstract : The amygdala is crucially involved in the acquisition and retention of fear memories. Experimental research on fear conditioning has shown that memory retrieval shortly followed by pharmacological manipulations or extinction, thereby interfering with memory reconsolidation, decreases later fear expression.

   Abstract : Anxiety disorders are very common and the primary feature is abnormal or inappropriate anxiety. Fear and anxiety is often mediated by the amygdala, a brain structure rich in substance P (SP) and neurokinin 1 (NK1) receptors. READ MORE

7. 5. The Amygdala, Arousal and Memory: From Lesions to Neuroimaging

   Author : Fredrik Åhs; Mats Fredrikson; Dieter Vaitl; Uppsala universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Psykologi; Psychology; Psykologi;

   Abstract : Emotional events are better remembered than neutral events. But what are the mechanisms behind this memory enhancing effect? It seems that they depend on the arousal level at the moment we experience the event to be remembered. READ MORE
