Luisier, Anne-Claude ; Petitpierre, Geneviève ; Ferdenzi, Camille ; Clerc Bérod, Annick ; Giboreau, Agnes ; Rouby, Catherine ; Bensafi, Moustafa

Atypical sensory functioning in Autism Spectrum Disorder (ASD) has been well documented in the last decade for the visual, tactile and auditory systems, but olfaction in ASD is still understudied. The aim of the present study was to examine whether children with ASD and neuro-typically (NT) developed children differed in odor perception, at the cognitive (familiarity and identification...

The importance of input data quality and quantity in climate field reconstructions – results from the assimilation of various tree-ring collections

Franke, Jörg ; Valler, Veronika ; Brönnimann, Stefan ; Neukom, Raphael ; Jaume-Santero, Fernando

Differences between paleoclimatic reconstructions are caused by two factors: the method and the input data. While many studies compare methods, we will focus in this study on the consequences of the input data choice in a state-of-the-art Kalman- filter paleoclimate data assimilation approach. We evaluate reconstruction quality in the 20th century based on three collections of tree-ring...

Striatal responsiveness to reward under threat‐of‐shock and working memory load : A preliminary study

Gaillard, Claudie ; Guillod, Matthias ; Ernst, Monique ; Torrisi, Salvatore ; Federspiel, Andrea ; Schoebi, Dominik ; Recabarren, Romina E. ; Ouyang, Xinyi ; Mueller-Pfeiffer, Christoph ; Horsch, Antje ; Homan, Philipp ; Wiest, Roland ; Hasler, Gregor ; Martin-Soelch, Chantal

Introduction: Reward and stress are important determinants of motivated behaviors. Striatal regions play a crucial role in both motivation and hedonic processes. So far, little is known on how cognitive effort interacts with stress to modulate reward processes. This study examines how cognitive effort (load) interacts with an unpredictable acute stressor (threat-of-shock) to modulate motivational...
