- Working Memory: Evaluates the ability to hold and manipulate facts in thoughts for quick periods. Prevalent tasks include things like digit span and letter-number sequencing.
- Processing Speed: Assesses how speedily and accurately one particular can execute simple or routine cognitive tasks. Tasks typically include symbol search and coding.
Added benefits of IQ Testing
