Objective: Many studies have suggested that there is a relationship between coherence and cognitive processes. This study aims at investigating this hypothesis through assessing the relationship between cognitive variables and coherence in the discourse of two groups of Persian-speaking younger and older adults. Methods: In order to evaluate our participants' cognitive capabilities, we recrui...

The objective of the study was to measure the interactions between visual thresholds for a simple light (the secondary task) presented peripherally and a simultaneously performed cognitive task (the primary task) presented foveally The primary task was highly visible but varied according to its cognitive complexity. Interactions between the tasks were determined by measuring detection threshold...

The present study investigated the effects of task type (cognitive vs. sensory) and source complexity (number of displays to be monitored) of the performance, workload, and stress associated with vigilance. Results affirmed the utility of the cognitive-sensory task distinction of the vigilance taxonomy, although in contrast to previous research the cognitive task was associated with lower perfo...

with regard to the impossibility of preparing learners for each situation that they might encounter in their life, it is more logical to teach them how to cope with unexpected challenges. helping learners ‘learn how to help themselves’ can be facilitated by means of tasks and activities in the classroom context. this paper presents some of the find- ings of a study on iranian young learners bet...

Task variation is an integrative method aiming at the importance of learner-to-learner interactions in a wide range of learning contexts and fostering authentic use of language and meaningful communication. This study investigated the impact of task variation on the accuracy and complexity of Iranian EFL learners’ oral speech. In so doing, 80 intermediate EFL learners, majoring English at the I...

OBJECTIVES While computed tomography colonography (CTC) has become a non-invasive alternative to traditional colonoscopy, superficial lesions tend be harder detect, with reports of <2 mm in height being missed. Therefore, for the evaluation lesion detectability using CTC, optimizing scan parameters becomes important. In this study, we investigate effect reconstructed matrix size from CTC on con...

Introduction: To study sentence comprehension in Persian-speaking Patients with Aphasia considering the factors of complexity. Methods: In this cross-sectional study, the performance of 6 non-fluent aphasic patients were tested and their performance was compared to 15 matched control group. Comprehension of semantically reversible sentences was assessed using a binary sentence-picture matching...
