The present study aimed to examine any possible relevance of perfectionism as a personal trait variable, in moderating the effectiveness of meta-cognitive instruction on bottom-up and top-down sub-processes of listening comprehension with a sample of EFL learners in Iranian context. To this end, 94 female EFL learners were selected from among 136 EFL learners at Andisheh Language Institute in M...

Although a peripheral auditory (bottom-up) deficit is an essential prerequisite for the generation of tinnitus, central cognitive (top-down) impairment has also been shown to be an inherent neuropathological mechanism. Using an auditory oddball paradigm (for top-down analyses) and a passive listening paradigm (for bottom-up analyses) while recording electroencephalograms (EEGs), we investigated...

Simultanagnosia is a visual cognitive disorder following a bilateral lesion in parieto-occipital brain areas. It affects the patients integrative perception so that scenes or hierarchically organized objects cannot be perceived as a whole but just in a piecemeal fashion. Qualitative explanations consider impairments of attentional selection mechanisms, feature binding, or global shape processin...

Introduction: Virtual bronchoscopy is a reliable and efficient diagnostic method for primary symptoms of lung cancer. The segmentation of airways from CT images is a critical step for numerous virtual bronchoscopy applications. Materials and Methods: To overcome the limitations of the fuzzy connectedness method, the proposed technique, called fuzzy connectivity - fuzzy C-mean (FC-FCM), utilized...

Evidence suggests that the neural system associated with face processing is a distributed cortical network containing both bottom-up and top-down mechanisms. While bottom-up face processing has been the focus of many studies, the neural areas involved in the top-down face processing have not been extensively investigated due to difficulty in isolating top-down influences from the bottom-up resp...

In PEPA, the calculation of the transitions enabled by a process accounts for a large part of the time for the state space exploration of the underlying Markov chain. Unlike other approaches based on recursion, we present a new technique that is iterative—it traverses the process’ binary tree from the sequential components at the leaves up to the root. Empirical results shows that this algorith...

ÐGeometric structure analysis is a prerequisite to create electronic documents from logical components extracted from document images. This paper presents a knowledge-based method for sophisticated geometric structure analysis of technical journal pages. The proposed knowledge base encodes geometric characteristics that are not only common in technical journals but also publication-specific in ...

background and aim: aging is accompanied with changes in cognitive capacities. in spite of advances in neural imaging technologies, there is not a straightforward method to observe cognitive functions. for assessing brain functions, researchers mainly use psychometric tests. the aim of this study was using consonant-vowel (cv) dichotic test as a non-invasive behavioral test for auditory attenti...
