a r t i c l e i n f o Keywords: HCI Eye-tracking Website complexity Cognitive load Task complexity Online shopping Online shopping is becoming one of the most popular applications on the Internet. Websites are the important interfaces in HCI (Human–Computer Interaction). Website design significantly affects online shopping behavior. This research used eye-tracker to track the eye-movement proce...

Gaming the system, a behavior where students disengage from a learning environment and attempt to succeed by exploiting properties of the system, has been shown to be associated with lower learning. Machine learned and knowledge engineered models have been created to identify gaming behaviors, but few efforts have been made to precisely identify how experts code gaming behaviors. In this paper,...

Based on the established framework of Cognitive Load Theory, the presented research focuses on the inspection of cognitive load factors in an interrupted learning task. The task itself is inspired from basic cognitive research and demands participants to learn abstract symbol combinations of varying complexity. In addition, they have to deal with interruptions while performing the task. Experim...

objectives: the role of cognitive process for postural control was shown in dual task studies. however, there was no definite evidence how verbal instructions influence the allocation of attention to postural control. this study determined whether young and elderly adult are able to deliberately control the resource allocation when performing a sensorimotor and cognitive task simultaneously and...

Research evidence reported to date demonstrates the differential effects of manipulating second language (L2) task conditions on the resultant production as measured in terms of complexity, accuracy, and fluency. The present study was aimed at adding to the available body of findings by exploring the synergistic effects of two task condition variables, namely online planning and immediacy (± He...

The  present  meta-analysis  was  conducted  to  provide  a  quantitative  measure  of  the overall effects of task complexity on Chinese EFL learners’ language  production.  Based  on  the strict inclusion criteria, 12 primary  studies  were synthesized according to key  features.  Eleven of them  were  meta-analyzed  to  investigate  effects  of  raising  the  resource-directing  task  comple...

been defined in various ways, including the level of embedding in a goal–subgoal hierarchy during problem-solving [6], the number of relations being simultaneously processed during reasoning [7], or the number of items held in working memory [8]. Reviews of RLPFC recruitment across multiple domains [2,9] show that activations are more frequent when the complexity of cognitive processing is high...

objective: the present study was aimed to correlate the clinical tests with the laboratory measures under dual task conditions in parkinson's disease (pd). materials and methods: eleven people with idiopathic pd (modified hoehn and yahr scores 1-3) were selected by simple non-probability sampling. center of pressure (cop) data obtained by force platform was used to calculate mean total velocity...

The ability to execute and maintain gait while performing simultaneous cognitive, verbal, or motor tasks ('dual-tasking') is beneficial in many ways. It is well-documented, however, that dual-tasking can result in cognitive or motoric interference that results in diminished gait performance, and impaired secondary task performance. When manipulating cognitive load, it is common to have particip...
