Abstract
The accurate measurement of the cognitive load a learner encounters in a given task is critical to the understanding and application of Cognitive Load Theory (CLT). However, as a covert psychological construct, cognitive load represents a challenging measurement issue. To date, this challenge has been met mostly by subjective self-reports of cognitive load experienced in a learning situation. In this paper, we find that a valid and reliable index of cognitive load can be obtained through item response modeling of student performance. Specifically, estimates derived from item response modeling of relative difficulty (i.e., the difference between item difficulty and person ability locations) can function as a linear measure that combines the key components of cognitive load (i.e., mental load, mental effort, and performance). This index of cognitive load (relative difficulty) was tested for criterion (concurrent) validity in Year 2 learners (N = 91) performance on standardize

Volvo Cars brought a new safety standard to the small premium SUV segment with the launch of the new Volvo XC40 in 2018. Being the first car to be built on Volvo’s new Compact Modular Architecture (CMA) platform, the Volvo XC40 is one of the safest cars in its segment thanks to its inheritance of safety and support technologies from the brand’s S90/V90 and XC60 models.
‘Cognitive Load’ Reduction
Modern city life presents complex challenges for drivers, pedestrians, cyclists and other road users. This is why the new Volvo XC40 was designed to reduce driver distraction and the so-called ‘cognitive load’ on the driver. With safety and driver assistance systems actively identifying and mitigating potential conflicts, the driving becomes more relaxed and enjoyable.
particularly malicious and malignant figure in the american political land and really in american history. i want to bring in now cnn political commentator scott jennings to join the group. scott, thanks for joining us. we re talking about propaganda and lies here. and i just want to read something. this is politico magazine. it published an article and it s called trump s lies versus your brain. it says certainly after the president took office the writer maria konikova describes research on how people sort out what s true and what s a lie in their brains. first they have to accept any statement as true to understand it and then reject a lie with true facts. but i want you to listen to np here s what it says. when we are overwhelmed with false or potentially false statements our brains pretty quickly become so overworked that we stop trying to sift through everything. it s called cognitive load, our limited cognitive resources are overburdened. it doesn t matter how implausible
