Incoherent discourse, with a disjointed flow of ideas, is a cardinal symptom in several psychiatric and neurological conditions. However, measuring incoherence has often been complex and subjective. We sought to validate an objective, intrinsically reliable, computational approach to quantifying speech incoherence. Patients with schizophrenia and healthy control volunteers were administered a v...

The degree of incoherence, when previsions are not made in accordance with a probability measure, is measured by the rate at which an incoherent bookie can be made a sure loser. We consider each bet from three points of view: that of the gambler, that of the bookie, and a neutral viewpoint. From each viewpoint, we de ne an normalization for each bet, and the sure loss for incoherent previsions ...

When affective experiences are inconsistent with activated evaluative concepts, people experience what is called affective incoherence; when affective experiences are consistent with activated evaluative concepts, people experience affective coherence. The present research asked whether incidental feelings of affective coherence and incoherence would regulate persuasion. Experiences of affectiv...

In previously identified forms of remote synchronization between two nodes, the intermediate portion of the network connecting the two nodes is not synchronized with them but generally exhibits some coherent dynamics. Here we report on a network phenomenon we call incoherence-mediated remote synchronization (IMRS), in which two noncontiguous parts of the network are identically synchronized whi...

Rationality is often defined in terms of coherence, assuming that a single syntactical rule such as consistency, transitivity, or Bayes’ rule suffices to evaluate behavior. Many normative claims made in psychological research follow this assumption. We argue that coherence-based norms are of limited value for evaluating behavior as rational. Specifically, we maintain that (a) there is little ev...

We show that averaging eigenvectors of randomly sampled submatrices efficiently approximates the true eigenvectors of the original matrix under certain conditions on the incoherence of the spectral decomposition. This incoherence assumption is typically milder than those made in matrix completion and allows eigenvectors to be sparse. We discuss applications to spectral methods in dimensionality...

Three properties of matrices: the spark, the mutual incoherence and the restricted isometry property have recently been introduced in the context of compressed sensing. We study these properties for matrices that are Kronecker products and show how these properties relate to those of the factors. For the mutual incoherence we also discuss results for sums of Kronecker products.

In “Epistemic Relativism,” Mark Kalderon defends a view that has become increasingly popular across various academic disciplines. He wrote his article in response to Paul Boghossian’s book Fear of Knowledge, in which epistemic relativism is criticized and dismissed as incoherent. Kalderon argues that Boghossian does not accurately characterize epistemic relativism resulting in a hasty dismissal...
