After reading it out loud, you should then decide whether the given answer is correct or incorrect.

The math problem will be something like: "Is 10/2 + 2 = 7 ?" and you will be asked to read it out loud (i.e., you should say "Is ten divided by two plus two equal to seven?"). On each trial, a sequence of math problems and words will alternate.

Make sure that you can see the full area before you begin the lab. If you have logged in, you'll see a rectangle below. This demonstration allows you to measure your operation span using the procedure of Conway & Engle (1996). Performance on simple span tasks usually correlate very highly with complex span tasks, but complex span tasks often correlate with a wider variety of tasks, including those that tap attention, than simple span. The primary difference is the presence (complex span) or absence (simple span) of a secondary task (e.g., the math problems). This type of task is often called a complex span task, and can be contrasted with a simple span task, such as
Engle and his colleagues have argued that this implies a general pool of resources that is used in every type of working memory situation. Operation span measures predict verbal abilities and reading comprehension even though the subjects are solving mathematical problems. The number of operation-word strings in a sequence is increased and decreased to measure the participant's operation span. After a series of problems and words has been presented, the participants recall the words that followed each operation. In this task, participants are asked to read and verify a simple math problem (such as "Is (4/2)-1=1 ?) and then read a word after the operation (such as SNOW). To determine whether there is a general capacity for all working memory tasks, Turner and Engle (1989) developed a task called operation-word-span or OSPAN. One question that has been posed is whether the capacity is specific to verbal tasks or if there is a general pool of resources that is used in every working memory task. This active process, however, seems to have a limited amount of resources to work with. Working memory is often viewed as a flexible workspace that not only stores information but also plays an active role in processing and manipulating information.
