Figures & data
Table 1. Demographic characteristics of participants and group internal comparisons for participant groups.
Table 2. Intraclass correlation coefficients and their 95% confidence intervals for mean cluster sizes and the number of switches.
Table 3. Descriptive statistics of total scores and temporal parameters in semantic and phonemic verbal fluency tasks.
Figure 1. Predicted values of words produced in the four 15-s segments in phonemic and semantic verbal fluency tasks. Error bars represent 95% confidence intervals.
Table 4. Number of participants who generate errors, total number of errors, distribution of error types and in semantic and phonemic verbal fluency tasks.
Figure 2. Estimates for the total score of phonemic and semantic tasks as a function of all predictor variables included in the models. For the sake of clarity, the continuous variable of centered mean cluster size is estimated on three levels. Error bars represent 95% confidence intervals. Note that due to the model selection procedure used, semantic but not phonemic model had education level as a predictor variable.
Table 5. Descriptive statistics of task congruent cluster size, number of task discrepant clusters and switches in semantic and phonemic verbal fluency tasks.
