The correlation between the cognitive accessibility of an object and the way of representing this object in the text when retelling a video plot or stories based on a set of pictures has been investigated. The key research method involves eliciting and documenting narratives. Two groups of subjects were tested: a group of schoolchildren 15—17 years old (N: 20) and a group of adults 35—40 years old (N: 21). Cognitive accessibility is understood as a parameter that consists of ontological accessibility (whether the object is accessible to the speaker in direct experience) and lexical accessibility (whether a well-mastered lexicalized way of naming the object is available to the speaker, i.e. a fixed specific word or expression). The following questions were posed: (1) is there a correlation between the cognitive accessibility of an object and the frequency of mentioning this object in the text; and (2) is there is a correlation between the cognitive accessibility of the object and the difficulties experienced by the speaker in naming the object, manifested in the observed symptoms of speech disfluencies. The first question was answered in the negative in both age groups. The second question in both age groups received a convincing positive answer: when mentioning an object with low cognitive accessibility, the subjects significantly more often demonstrated symptoms of speech disfluencies than when mentioning an object with high cognitive accessibility.
