1. 11. Volitional and strategic retrieval-orientation adoption in reality monitoring: an ERP study

   Kandidat-uppsats, Lunds universitet/Institutionen för psykologi

   Författare :Nils Nyberg; [2016]
   Nyckelord :recognition memory; retrieval orientation; reality monitoring; event-related potentials; multinomial processing tree models; Social Sciences;

   Sammanfattning : Retrieval orientations refer to cognitive states that, if adopted, tonically orients episodic retrieval attempts towards the sought-after type of information. Such orientations can enhance episodic retrieval by modulating the processing and effectiveness of retrieval cues. LÄS MER

3. 12. BRAIN ACTIVITY EFFECTS OF AWARENESS FOR EVOLUTIONARILY THREATENING STIMULI INVESTIGATING THE SNAKE DECTECTION HYPOTHESIS : INVESTIGATING THE SNAKE DETECTION HYPOTHESIS

   Magister-uppsats, Umeå universitet/Institutionen för psykologi

   Författare :Simone Grassini; [2016]
   Nyckelord :Evolution; ERP; EPN; Snake Detection Hipothesis;

   Sammanfattning : Snakes are probably the best example of evolutionarily life-threatening stimulus as they have been one of the first predators of primates and mammals in general. In recent years, it has been shown that snake images produce specific behavioral and electrophysiological reactions in humans, provoking enhanced brain activity over the occipital cortex compared with pictures of other animals.

4. 13. Is Visual Stimuli Neighboring Attended Stimuli Suppressedin High Perceptual Load? : A Steady State Evoked Potential Study

   Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

   Författare :Linn Bergström; [2016]
   Nyckelord :;

   Sammanfattning : Perceptual load theory, together with the surround-suppression model suggest that stimulus surrounding attended stimuli is suppressed, especially if perceptual load is high. This study attempts to map surround-suppression using electroencephalography to measure neural activity related to suppression at four surrounding locations (2°, 3°, 4° and 6° from fixation).

5. 14. Qualitative differences in L3 learners' neurophysiological response to L1 versus L2 transfer

   Magister-uppsats, Stockholms universitet/Institutionen för lingvistik

   Författare :Alejandra Keidel Fernández; [2016]
   Nyckelord :EEG; Language acquisition; Morphosyntax; TLA; grammar; P300;

   Sammanfattning : In the present study, the influence of morphosyntactic aspects of L1 and L2 on L3 comprehension is investigated using ERP (Event-Related Brain Potentials). The study examines the processing of verb and gender agreement incongruences in Spanish by native Swedish speakers that are fluent in English and learning Spanish, in comparison to a control group of native Spanish speakers.

7. 15. Content dependence of the neural correlates of recollection: ERP old/new effects for faces, objects and words

   Kandidat-uppsats, Lunds universitet/Institutionen för psykologi

   Författare :Emma De Graaf; Anna Karlsson; [2014]
   Nyckelord :recollection; old new effects; material specificity; event-related potentials; Recognition memory; Social Sciences;

   Sammanfattning : As previous research on content-specificity of the neural correlates of recollection is inconclusive, event-related potentials were used to assess old/new effects for faces, objects and words. The data demonstrate temporal differences in ERP old/new effects as a function of item type, supporting the notion that material-dependent processes underlie recollection-related neural activity.
