Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The study parameters per testing moment and per participant are the parameters of the word frequency distribution; the parameters of the AoA distribution; and the parameters of the distribution of number of WordNet-connections. Combined, these parameters will provide a good estimate of the number of lexical connections per word. | — |
Secondary
| Measure | Time frame |
|---|---|
| The second objective of this study is to predict differences in score on (part of) the AAT between early and later stages of aphasia on the basis of the parameters that are examined as a first objective. The secundary study parameters are thus identical to the primary study parameters. | — |
