2. 1. Valence-Level Dependent Presentation-Order Effects in Preference Judgments

   Author : Mats P. Englund; Åke Hellström; William M. Petrusic; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Preference judgment; order effects; stimulus valence; sensation weighting; feature matching; comparison direction; Psychology; Psykologi; Psychology; psykologi;

   Abstract : Reversal of the stimulus-presentation order often affects the outcome in paired stimulus comparison. Psychophysicists have found that the size and direction of the order effects depend on the compared stimuli’s magnitudes, but this magnitude dependence does not seem to have been recognized previously in cognitive research on preference judgment.

4. 2. Fear commands attention : snakes as the archetypal fear stimulus?

   Author : Sandra C Soares; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Information regarding successful solutions to environmental hazards has accumulated in the gene pools of species, as a result of evolution. Therefore, from an evolutionary viewpoint, fear has played a central role in shaping mammalian genotypes. READ MORE

5. 3. Partial Discharge Analysis of Stator Insulation at Arbitrary Voltage Waveform Stimulus

   Author : Xiaolei Wang; Hans Edin; Joachim Holböll; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Partial discharge (PD) detection is a powerful tool to diagnose the defects and degradation in high voltage electrical insulation systems. It can be performed in both on-line and off-line conditions. READ MORE

6. 4. Chemical and stimulus-induced NMDA-dependent plasticity and the possible involved mechanisms

   Author : Rui Li; Göteborgs universitet; []
   Keywords : synaptic plasticity; hippocampus; LTP; LTD; AMPA; NMDA; NR2A; NR2B;

   Abstract : Long-term potentiation (LTP) and long-term depression (LTD) are considered as the most important forms of synaptic plasticity involved in learning and memory. The traditional way to induce LTP and LTD is by electric stimulation leading to activation of NMDA-R. READ MORE

7. 5. Electrophysiological correlates of consciousness

   Author : Rasmus Eklund; Stefan Wiens; Mats Nilsson; Antti Revonsuo; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; neural correlates of consciousness; electroencephalography; event-related potentials; visual awareness negativity; auditory awareness negativity; recurrent processing; phenomenal consciousness; access consciousness; Psychology; psykologi;

   Abstract : How does the brain enable us to experience seeing or hearing a stimulus? If a stimulus is repeatedly presented at the awareness threshold, subjects will report that they are aware of the stimulus on half of the presentations. Electroencephalography (EEG) can be used to non-invasively record neural activity as event-related potentials (ERPs). READ MORE
