Speech-free instruction
A language-free instruction is an instruction to act that can be given without using language or understanding language . This means that the content is conveyed with the help of standardized gestures and facial expressions .
The central point is that people who would be disadvantaged by the linguistic instruction and people with disabilities can understand an instruction and can carry out the required action as well as non-impaired people. Impairments include, for example, hearing impairment or fundamental difficulties in understanding speech. Disadvantages include: B. not speaking the original language of the instruction as well as cultural differences that could influence the understanding of the linguistic instruction. In the psychological-diagnostic field, speech-free instructions therefore play an important role. Many psychological test procedures have the option of testing speech-free. This initially expands the test use, which means that the psychological test procedure can be used for a larger target group.
In its practical implementation, speech-free instruction initially enables people with impairments to be compared with one another, as well as a comparison with people without impairments. It also helps ensure that a test procedure meets the “fairness” quality criterion, which is of great practical importance. This means first of all "speaking fairness", which means that the processing of the tasks and the results obtained from them are independent of the vocabulary and the style of speaking of the test person. With "culture fairness" it is important to counteract the disadvantage caused by a different mother tongue and / or cultural differences. Before a language-free instruction of a psychological-diagnostic test procedure is used, its equivalence should be checked using an equivalence test so that it does not produce results that differ from those obtained with language instruction.
