Working Memory: Evaluates the ability to hold and manipulate information and facts in mind for quick periods. Typical tasks consist of digit span and letter-number sequencing.
Processing Speed: Assesses how swiftly and accurately one can carry out easy or routine cognitive tasks. Tasks usually include things like symbol search and coding.


Positive aspects of IQ Testing
IQ tests supply quite a few added benefits, including:


Educational Placement: IQ tests can enable recognize students who need particular educational solutions or sophisticated programs. Schools frequently use IQ test final results to place students in gifted applications or to deliver further assistance for these with mastering difficulties.
