Studying emotion theories through connectivity analysis: Evidence from generalized psychophysiological interactions and graph theory

Studying Graph Connectivity

Language, Emotion and Metapragmatics: A Theory Based on Typological Evidence

Humans are equipped with some universal or language-specific abilities to recognize emotions. However, because of the different emotional contents in diverse languages and the relevant cultural differences, humans with different cultural backgrounds own different metapragmatical abilities to recognize and express emotions. A hypothesis concerning emotional effects about intonation and particle ...

Tools of the trade: psychophysiological interactions and functional connectivity.

Psychophysiological interactions (PPIs) analysis is a method for investigating task-specific changes in the relationship between activity in different brain areas, using functional magnetic resonance imaging (fMRI) data. Specifically, PPI analyses identify voxels in which activity is more related to activity in a seed region of interest (seed ROI) in a given psychological context, such as durin...

Direct versus Representational Theory of Perception: Evidence from psychophysiological data

Die Komponenten der ereigniskorrelierten Hirnpotentiale (EKP) werden in zahlreichen Untersuchungen als Manifestationen bestimmter Stufen bzw. Mechanismen in der Informationsverarbeitung betrachtet. Aus der Sicht der ökologischen Wahrnehmungstheorie könnten sie aber alternativ als Korrelate der Informationsextrahierung aus dem (experimentellen) Umfeld angesehen werden. In einer Reihe von hier be...

Boundary-connectivity via Graph Theory

We generalize theorems of Kesten and Deuschel-Pisztora about the connectedness of the exterior boundary of a connected subset of Zd, where “connectedness” and “boundary” are understood with respect to various graphs on the vertices of Zd. These theorems are widely used in statistical physics and related areas of probability. We provide simple and elementary proofs of their results. It turns out...
