The Speeded Processing Tasks require participants to name many stimuli aloud as quickly and accurately as possible. There are four versions, each with different types of stimuli: colours, small quantities (i.e., 1 – 3 dots), letters, and digits. Each version of the Speeded Processing Tasks has two forms, Form A and Form B, in order to ensure reliability. For each form, the experimenter records naming speed in seconds (i.e., how long it takes to name the stimuli) and accuracy (i.e., the number of errors committed). The Speeded Processing Tasks are quick and easy to administer; please see the experimenter instructions for details. 

Speeded Processing of Colours

Speeded Processing of Symbols: Letters

Speeded Processing of Symbols: Digits

Speeded Processing of Small Quantities

Note: The experimenter instructions were designed for use with adults, but these tasks could also be used with young children, assuming the children are familiar with the stimuli they have to name. The practice sheets for each task can help determine whether the children are in fact familiar with the stimuli. Even very young children (3 – 4 years) are aware of their colours. Children have to know the letters A, C, and M, and the digits 1, 2, and 3 to complete the Speeded Processing of Symbols – Letters and Digits.

Young children (around 3 years of age) are also capable of completing the Speeded Processing of Quantities, however the instructions should be modified to inform children that they need to “say the number of dots without counting”.
