In cognitive psychology, cognitive load is the effort being used in the working memory.According to work conducted in the field of instructional design and pedagogy, broadly, there are three types of cognitive load: intrinsic cognitive load is the effort associated with a specific topic; extraneous cognitive load refers to the way information or tasks are presented to a learner; and germane ...
John Sweller (born 1946) is an Australian educational psychologist who is best known for formulating an influential theory of cognitive load. [1] He is currently (i.e., 2020) Professor Emeritus at the University of New South Wales .
The worked-example effect is a learning effect predicted by cognitive load theory. [1] [full citation needed] Specifically, it refers to improved learning observed when worked examples are used as part of instruction, compared to other instructional techniques such as problem-solving [2] [page needed] and discovery learning.

Chandler and Sweller found through empirical study that the integration of text and diagrams reduces cognitive load and facilitates learning. [5] They found that the split-attention effect is evident when learners are required to split their attention between different sources of information (e.g., text and diagrams).
The cognitive perspective focuses on the cognitive processes involved in learning as well as how the brain works. [7] The emotional perspective focuses on the emotional aspects of learning, like motivation, engagement, fun, etc. [8] The behavioural perspective focuses on the skills and behavioural outcomes of the learning process. Role-playing ...
The Scapegoat Theory suggests that dominant groups can position “unfocused aggression” on minorities. [ 8 ] Throughout history, there have been several notable social movements of minorities leading to revolutions; while the revolutions are remembered by the public, those who have been leading the change have often been forgotten.

A minimum systolic value can be roughly estimated by palpation, most often used in emergency situations, but should be used with caution. [10] It has been estimated that, using 50% percentiles, carotid, femoral and radial pulses are present in patients with a systolic blood pressure > 70 mmHg, carotid and femoral pulses alone in patients with systolic blood pressure of > 50 mmHg, and only a ...
