    Aim. The Verbal Fluency task is one of the naming tasks and it is generally used in clinical neuropsychology and logopedics to investigate for example word retrieval strategies and cognitive flexibility. Previous studies have shown that fluency skills increase strongly as the child grows. So far little is known about the quantitative fluency skills in children under six years of age. The aim of this study is to examine how Finnish-speaking healthy and typically developed children perform a semantic verbal fluency task. The task was divided into six different semantic categories. The aim of the study is to find out whether there is a difference between the performance of 3-year-old, 4-year-old and 5-year-old children, and whether gender has an effect on performance. In addition, the children's performance of the fluency task is compared to their performance in Boston Naming Test and Rapid Automatized Naming Test of pictures and colours to find out whether there is any congruence between the fluency task and the naming tests. Methods. The data was gathered in three different day-care centers in Helsinki from 30 children ages 3 to 5. The children were tested at the day-care centers and their performance was recorded with a dictation machine. Testing was divided into two sections of which the first included the naming tests and the second all the fluency categories. The data was analysed using mainly statistical methods. Results. The results show that age has a significant impact on fluency skills. The largest amounts of correct words were produced by the 5-year-old and the smallest amounts by the 3-year-old children. The older children also made fewer errors than the younger children. All children produced more nouns than verbs. The gender had no impact on the performance in the semantic fluency task, the Boston Naming Test or the Rapid Automatized Naming Test. The results also show some connections between fluency task and naming tests.

    Semantic fluency task is often used as part of an assesment to investigate children’s lexical development. Semantic fluency task measures the ability to generate words within a certain category and within a restricted amount of time. In previous studies, children’s semantic fluency skills have increased as the child grows. In addition, word retrieval strategies have been found to enhance word recall in the semantic fluency task with school-aged children and adults. However, there is only little knowledge regarding the use of word retrieval strategies in the semantic fluency task with preschool aged children. So far, in previous studies word retrieval strategies in the task have not been investigated with children under the age of 4. The aim of this study was to examine whether there are differences in 2 to 5 year old children’s performance in the semantic fluency task and whether children’s gender or their parent’s socioeconomic status had an impact on their performance. In addition, the children’s ability of using word retrieval strategies were explored and the relation between the use of word retrieval strategies and the number of correct words were evaluated. The study sample included 79 children. Children completed two semantic fluency tasks guided by their parents in an online questionnaire. During the tasks, the children generated words belonging to the semantic category of animals and clothes within a minute. The performance was evaluated on the basis of the number of correct words, errors and error types. Word retrieval strategies were studied by examining clusters, semantic subcategories and switches between subcategories. The results of this study showed that age had a strong relation to performance on fluency tasks as measured with a number of correct words, clusters, semantic subcategories and switches. The new result was that even 2 year old children could generate correct words for the task and utilize word retrieval strategies in the tasks. The children’s gender or parents’ socioeconomic status had no effect on performance in the semantic fluency tasks. Number of clusters, semantic subcategories and switches had a positive relation to the number of correct words which indicated that successful word retrieval required use of fluency strategies even with preschool aged children. However, due to the lack of previous research data, more research regarding children’s word retrieval strategies is necessary. This study is the first in which the children’s word fluency task was guided by their parents. Clinical practice and further studies could benefit from these results that such a research design would appear to be suitable for assessing children’s semantic fluency.
