New, unusual, and changing events are important environmental cues, and the ability to detect these types of stimuli in the environment constitutes a biologically significant survival skill. We used event-related potentials to examine whether sensory and cognitive neural responses to unattended novel events are modulated by the complexity of a primary visuomotor task. Event-related potentials w...

Introduction: The current study aimed to elucidate the role of preparatory cognitive control in decision making and its neural correlates using functional Magnetic Resonance Imaging (fMRI). To this effect, by employing a series of new cognitive tasks, we assessed the role of preparatory cognitive control in monetary (risky) decision making. Methods: The participants had to decide between a...

while parkinson's disease (pd) has traditionally been defined by motor symptoms, many researches have indicated that mild cognitive impairment is common in non-demented pd patients. the purpose of this study was to compare verbal fluency performance in non-demented parkinson's disease patients with healthy controls.in this cross-sectional study thirty non-demented parkinson's disease patients a...

the optimum fermentation times of black tea manufactured by two systems of orthodox and ctc (cut, tear & curl) were investigated by measuring the quality parameters of black tea, like: theaflavin, thearubigin, highly  polymerized substances and total liquid colour during the fermentation stage. optimum fermentation times from the beginning of fermentation were determined to be 60 min and 15...

This paper follows the scenarios and task models debate by reviewing the contributions of task modelling and scenario based approaches from a cognitive perspective. A framework of cognitive affordances is introduced to discuss the merits and limitations of each approach. An extension of the modelling theme, generic task models, is proposed to augment the contribution of knowledge reuse to the d...

One of the major criticisms leveled at task-based language teaching (TBLT), despite its countless merits, is developing fluency at the cost of accuracy. The post-task stage affords a number of options to counteract this downside through task repetition and task recycling. These two options are considered to positively affect learners' oral performance in terms of fluency, accuracy, and complexi...

In virtual acoustic imaging systems, the perception of a sound source anywhere in space can theoretically be reproduced for one listener by using only two loudspeaker and an appropriate set of filters, called crosstalk cancellation (CTC) filters. However, the ideal position of the loudspeakers in such systems is still a question that is currently addressed by many researchers. Several analytica...

conclusions to our knowledge, this is the first case of ctc that was identified incidentally in the retrocaval position and caused intermittent obstruction of vena cava. case presentation the present study reports on a 66-year-old female with coronary artery disease (cad) who was scheduled for coronary artery bypass grafting (cabg) at our hospital. during mediastinal exploration and pericardiot...

In this research, we use user defined labels from three internet text sources (Reddit, StackExchange, Arxiv) to train 21 different machine learning models for the topic classification task of detecting cybersecurity discussions in natural English text. We analyze false positive and negative rates each model’s cross validation experiments. Then present a Cybersecurity Topic Classification (CTC) ...

Central to any task-based syllabus is the notion of complexity. Proponents of task-based language teaching (TBLT) have argued that tasks be sequenced according to their inherent cognitive complexity, partially because learner performance changes according to the complexity of the task. This exploratory study examines the effect of task complexity on the linguistic complexity of task performance...
