Visual cognition is of significant importance in certain imaging applications, such as security and surveillance. In these applications, an important issue is to determine the cognition threshold, which is the maximum distortion level that can be applied to the images while still ensuring that enough information is conveyed to recognize the scene. The cognition task is usually studied with imag...

In the present study, two different models of task complexity; namely, limited attentional capacity model and cognition hypothesis were examined. To this end, the manipulation of cognitive task complexity along +/- single task dimension on Iranian EFL learners’ production in terms of fluency was explored. Based on the results of the writing test of TOFEL (2004), 48 learners were selected as the...

the purpose of the present study was to provide empirical support for the construct of the involvement load hypothesis (ilh ) in an efl context. to fulfill the purpose of the study, 4 intact groups consisting of 126 intermediate-level students participated in this experiment. in order to ensure that the participants were at the same level of english language proficiency, the nelson test was adm...

Our hypothesis is that reflective cognition is necessary to achieve expert level performance in certain skills, and that reflective cognition can be seen as a secondary task in skill acquisition. To investigate to what extent people use and acquire complex skills and strategies in the domains of reasoning about others and natural language use, an experiment was conducted in which it was benefic...

The social brain hypothesis assumes the evolution of social behaviour changes animals' ecological environments, and predicts evolutionary shifts in social structure will be associated with changes in brain investment. Most social brain models to date assume social behaviour imposes additional cognitive challenges to animals, favouring the evolution of increased brain investment. Here, we presen...

We provide an axiomatic foundation of the expected utility preferences over lotteries on roles in simple superadditive games represented by the two main power indices, the Shapley-Shubik index and the Banzhaf index, when they are interpreted as von NeumannMorgenstern utility functions. Our axioms admit meaningful interpretations in the setting proposed by Roth in terms of di®erent attitudes tow...
