Cross-cultural psychologists seek to understand the nature of culture, a concept that can only be understood at the collective, supra-individual level. In most areas of psychology, researchers treat each individual as a separate source of data. Crosscultural psychologists therefore need a clear understanding of the relationship between individual-level and group or collective-level analysis. Se...

The processing of fluent speech involves complex computational steps that begin with the segmentation of the continuous flow of speech sounds into syllables and words. One question that naturally arises pertains to the type of syllabic information that speech processes act upon. Here, we used functional magnetic resonance imaging to profile regions, using a combination of whole-brain and explor...

This study aims at examining the accentual and phrasing properties of a variety of L2 French commonly called “Français Fédéral”, a variety of French spoken in Switzerland by speakers who have a Swiss-German dialect as a mother tongue. For this, we compared the data of 4 groups of 4 speakers: 2 groups of 4 native French speakers from Neuchâtel and from Paris, and 2 groups of 4 Swiss-German Frenc...

Anatomical studies of primate prefrontal cortex show strong and spatially modulated lateral excitatory connections among pyramidal neurons in the supra-granular layers. We study the role of patchy lateral excitatory connections in generating spatially localized pulses of sustained activity. When the patchy connections drive the "ring no spatially localized sustained activity is possible. When t...

It has been suggested that the human ability to process number and time both rely on common magnitude mechanisms, yet for time this commonality has mainly been investigated in the sub-second rather than longer time ranges. Here we examined whether number processing is associated with timing in time ranges greater than a second. Specifically,we tested longduration estimation abilities in adultsw...
