摘要

“如今在俄罗斯,关于医学生和毕业生与非典型发育(AD)儿童互动的准备程度的系统数据不足。我们开发了一种方法学方法来评估医学生与AD儿童的相互作用。这项工作使用了一个感知实验,在这个实验中,学生们被展示了包含典型发育(TD)和AD(唐氏综合症,自闭症谱系障碍)儿童语音信号的测试序列。在感知实验中,听众的行为被同时录像下来,用FaceReader软件通过他们的面部表情来确定他们的真实情绪状态,从而验证他们的答案。在知觉实验前后,采用一系列的心理测试来评估学生的心理情绪状况。此外,还测定了受试者的心理生理和生理参数。在第一阶段的工作中,使用了16名TD和AD儿童(11名男孩,5名女孩)的言语,听者是25名一年级儿科学生和5名儿童言语领域的专家。通过统计分析发现,听者(俄语为母语者)的心理生理特征:功能性侧不对称特征、音位听觉形成指标、言语侧偏好系数与AD儿童性别、年龄、心理神经状态(TD -发育障碍)和障碍严重程度的成功识别存在相关性。确定了专家分类为“易读”和“难读”的单词的声学参数。本研究由俄罗斯科学基金资助(项目19-78-00057)。

DETERMINATION OF CORRELATIONS BETWEEN SUBJECTS’ PSYCHOPHYSIOLOGICAL PARAMETERS AND THE RESULTS OF THE PERCEPTUAL EXPERIMENT
"Nowadays in Russia, there are insufficient systematized data on the degree of preparedness of medical students and graduates to interact with children with atypical development (AD). We have developed a methodological approach to assess the interaction of medical students with AD children. The work uses a perceptual experiment during which students are presented with test sequences containing speech signals of children with typical development (TD) and AD (Down syndrome, autism spectrum disorders). During the perceptual experiment, the listeners’ behavior was being video-recorded in parallel to verify their answers using the FaceReader software determining the true emotional state by their facial expression. The students’ psycho-emotional status was evaluated using a battery of psychological tests before and after the perceptual experiment. Additionally, the subjects’ psychophysiological and physiological parameters were determined. At the first stage of the work, the speech of 16 TD and AD children (11 boys and 5 girls) was used, the listeners were 25 1st-year pediatric students and 5 experts in the field of child speech. The statistical analysis revealed correlations between the listeners’ psychophysiological characteristics (Russian-native speakers): the profile of functional lateral asymmetry, formation indicators of the phonemic hearing, the coefficient of lateral preference by speech and the success in recognizing the children’s gender, age, psychoneurological state (TD – developmental disorders), and the severity of disorders in AD children. The acoustic parameters of words classified by experts as “legible” and “illegible” were determined. The work is financially supported by the Russian Science Foundation (project 19–78–00057)."
