How is the AHA done?

Play is used as the basis for the observation and toys from the AHA test-kit are presented playfully and without instructions as to which hand to grasp or hold with. The AHA is performed as an enjoyable, approximately 15 minutes play-session. The toys in the AHA test kit are attractive and elicit bimanual use. The session is video recorded and the scoring is done as a second step from viewing the video. This makes it possible for the play conductor to interact with the child and make the play session a fun and pleasant experience. The play itself is the focus for the child, the objects are interesting and exciting and the play conductor can assist, if needed, to make the performance successful. This makes the test situation attractive to children and parents, and also to therapists. It also promotes typical use of the two hands.

The AHA test kit consists of a number of specific toys gathered in a children's suitcase. A detailed manual includes the rationale and the purpose of the test, test procedures, psychometric properties, scoring criteria and score forms.

There are two versions of the test:

-Small Kids AHA: The test session consists of play involving handling and exploring objects from the AHA test kit for children 18 months to 5 years of age.

-School Kids AHA: The same objects are used but in an age appropriate context using board games for children 6-12 years of age.

Criteria for scoring are the same for both versions and are described in the manual.
