Influence of Task Content on Writing Productivity in Sensory Agraphia: An Experimental Study

2012. Vol. 9. No. 3. P. 114–121 [issue contents]

The research addresses the mechanisms and change patterns of the psychological structure of written speech in agraphia associated with differences in the content of written tasks. The organization of the psychological processes that underlie writing is considered to be an active process that has adaptive value and takes place in the context of specific tasks set before the person. An empirical research program is proposed combining the traditional approach to agraphia diagnostics with analysis of changes in writing productivity associated with writing tasks of cultural-historic content. There were three special experimental tasks: on communicative, mnestic and regulative functions of writing. People with diagnosed blood stroke in the pool of medium brain artery took part in the study. There were 25 subjects of age range 36 – 70. The number of mistakes made during the written task performance was used as a measure of writing productivity. The results of statistical analysis with the criteria Friedman χ2 and Wilcoxon T-criterion allowed identifying significant differences in performance during traditional and non-traditional tasks in each group of subjects. All the tasks with the exception of dictation that touched the affected in the sensory aphasia part of the acoustic gnosis showed significant differences from the tasks that actualize communicative and mnestic functions. The number of mistakes in the tasks of writing and remembering the narrative pictures significantly exceeded the number of mistakes in the tasks of written naming (z = 2.442, p = .015; z = 3.164, p = .002) and forming sentences (z = 2.386, p = .017; z = 3.700, p = .000). The acquired results allow a conclusion of changes in productivity of writing in dependence to the content of the written speech. It is found that the tasks that actualize culturally determined functions of writing influence differently on the productivity of writing, which is determined by the specifics of psychological content of the given tasks.
