Twisting Tongues and Twisting Arms: The Power of Political Rhetoric

Twisting tongues to test for conflict-monitoring in speech production

A number of recent studies have hypothesized that monitoring in speech production may occur via domain-general mechanisms responsible for the detection of response conflict. Outside of language, two ERP components have consistently been elicited in conflict-inducing tasks (e.g., the flanker task): the stimulus-locked N2 on correct trials, and the response-locked error-related negativity (ERN). ...

Helical twisting power and scaled chiral indices

Chirality of optically active liquid crystal molecules has become an important research topic and the subject of a number of theoretical and experimental studies. We present here the results of the application of a newly developed scaling method of a chiral index to a range of chiral molecules. Good agreement is found between the scaled chiral index and the helical twisting power for relatively...

Twisting tongues and memories: Explorations of the relationship between language production and verbal working memory.

Many accounts of working memory posit specialized storage mechanisms for the maintenance of serial order. We explore an alternative, that maintenance is achieved through temporary activation in the language production architecture. Four experiments examined the extent to which the phonological similarity effect can be explained as a sublexical speech error. Phonologically similar nonword stimul...

Calculating the helical twisting power of chiral dopants{

This paper describes a Monte Carlo simulation technique designed to predict the sign and magnitude of the helical twisting power, bM, of a chiral material. The method calculates the chemical potential difference, Dm, between a chiral dopant and its enantiomer when they are placed in a twisted nematic solvent. In the low concentration limit, Dm is directly proportional to bM. In the simulations ...
