Recent language testing research investigates factors other than language proficiency that may be responsible for systematic variance in language test performance. One such factor is the test takers' cognitive styles. The present study was carried out with the aim of finding the probable effects of Iranian EFL learners' cognitive styles on their performance on communicative tests. For purposes ...

Combinatorial rigidity theory seeks to describe the rigidity or flexibility of bar-joint frameworks in R in terms of the structure of the underlying graph G. The goal of this article is to broaden the foundations of combinatorial rigidity theory by replacing G with an arbitrary representable matroid M . The ideas of rigidity independence and parallel independence, as well as Laman’s and Recski’...

To investigate whether visual field dependence-independence changed after unilateral vestibular loss, Menière's patients were tested before and after unilateral vestibular neurotomy and compared with controls. Using the rod and frame test, visual vertical perception was tested under four visual contexts (with a frame tilted either clockwise or counterclockwise, with a vertical frame, and withou...

The study investigated the extent to which two types of instructional materials and learner field dependence–independence affected learners’ cognitive load, time spent on task, and problem-solving performance in a complex system with a computer-modeling tool. One hundred and one primary student teachers were initially categorized into field dependent, field mixed, and field-independent learners...

Interpolating fields, used to excite hadrons from the QCD vacuum in nonperturbative field-theoretic investigations of hadron properties, are explored with an emphasis on unconventional nucleon interpolators. The QCD continuum model for excited state contributions to QCD correlation functions is a central element in extracting the physics contained in these alternate correlation functions. The a...

Gaussian random field on general ultrametric space is introduced as a solution of pseudodifferential stochastic equation. Covariation of the introduced random field is computed with the help of wavelet analysis on ultrametric spaces. Notion of ultrametric Markovianity, which describes independence of contributions to random field from different ultrametric balls is introduced. We show that the ...

Forty unpaid normal volunteers (20 men and 20 women) were given the Autokinetic Test, the Embedded-Figures Test, and the Rod-and-Frame Test prior to instruction in the Transcendental Meditation technique. After three months of regular meditation subjects were retested and demonstrated increased ego-distance and field independence, as compared with controls, on all of the above tests. These rema...
