Learning disorder, learning disability and learning difficulty are often used interchangeably, they differ in many ways. Learning disability refers to significant learning problems in an academic area. These problems, however, are not enough to warrant an official diagnosis. Learning disorder, on the other hand, is an official clinical diagnosis, whereby the individual meets certain criteria, as determined by a professional (psychologist, pediatrician, etc.) The difference is in degree, frequency, and intensity of reported symptoms and problems, and thus the two should not be confused. When the term "learning disabilities" is used, it describes a group of disorders characterized by inadequate development of specific academic, language, and speech skills. Types of learning disabilities include reading disability (dyslexia), mathematics disability (dyscalculia) and writing disability (dysgraphia). The unknown factor is the disorder that affects the brain's ability to receive and process information. This disorder can make it problematic for a person to learn as quickly or in the same way as someone who is not affected by a learning disability. People with a learning disability have trouble performing specific types of skills or completing tasks if left to figure things out by themselves or if taught in conventional ways. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
