Working Memory: Evaluates the ability to hold and manipulate data in mind for short periods. Typical tasks involve digit span and letter-number sequencing.
Processing Speed: Assesses how immediately and accurately 1 can carry out basic or routine cognitive tasks. Tasks frequently contain symbol search and coding.


Advantages of IQ Testing
IQ tests present a number of positive aspects, such as:


Educational Placement: IQ tests can help determine students who want unique educational solutions or advanced applications. Schools generally use IQ test outcomes to place students in gifted programs or to supply added assistance for those with understanding difficulties.
