Firstly, Dworzynski et al. (2007, 2008) reported that aetiological and phenotypic overlap between autistic traits and validated, in-person expressive vocabulary tests was still low (albeit, with the two measures administered at different ages).
The finger tapping test has shown improvement in performance up to 9 years of age [ 17]. 2. Expressive speech test was administered to rule out speech related deficits.
In the expressive language test, 13 children (16.7%) scored ≥ 1 SD below the norm on grammar and vocabulary.
At post-test, expressive language was standardised assessed with the two production subtests of the SETK-2; in addition, parents completed the ELFRA-2 questionnaire.
At follow-up, expressive language was tested with the two production subtests of the SETK 3 5, a standardised and norm-referenced instrument to examine the language status of German speaking preschool children (reliability coefficients 0.62 0.86).
These domains were assessed by tests of expressive vocabulary and mean length of utterance, two important measures of expressive language competence.
Three children could not be successfully tested on expressive language, and one child could not be tested either on expressive or on receptive language.
In a case control design, 11 community controls (CC) with FLS were compared to 47 CC without FLS on tests of expressive and receptive language, visual motor coordination, full scale intelligence and verbal memory.
Similar results were seen for the tests of expressive language on the EVT-2, with a low mean standard score in the pretest results (M = 78.8, SD = 19.5) and a large increase over 6 months for both treatment and control groups (M = 85.6, SD = 15.0).
Teachers noticed it, and testing revealed that she had a freakishly high score on tests measuring expressive language ability.
