Used not only within clinical and educational settings, it is also used within the pharmaceutical and transport sectors, and finds further application in areas such as sports psychology.

Product Description

The d2 consists of 14 test lines with 47 characters in each line. Each character consists of a letter, 'd' or 'p' marked with one, two, three or four small dashes. The test taker is required to scan the lines and cross out all occurrences of the letter 'd' with two dashes while ignoring all other characters.
