Though some studies suggest that older adults are not differentially impacted by foreign-accented speech relative to younger adults, other studies indicate that older adults are poorer at perceiving foreign-accented speech than younger adults. The present study sought, first, to clarify the extent to which older and younger adults differed in their perception of foreign-accented speech. The secondary aim was to elucidate the extent to which the cognitive mechanisms supporting accented speech perception differ for older and younger adults. The data indicated that older adults were poorer at perceiving accented speech than younger adults. Older adults' speech perception accuracy was associated with a significant main effect of working memory as well as significant interactions between hearing acuity and cognitive flexibility and between hearing acuity and inhibitory control. Younger adults' speech perception accuracy, in contrast, was associated with a significant interaction between hearing acuity and processing speed. It therefore appears that the differences in performance between younger and older adults observed here may be attributable to differences in the cognitive mechanisms that support accented speech perception.
Although older and younger adults had equivalent performance identifying words produced by talkers with dysarthria, older adults appear to utilize more cognitive support to identify those words.
В статье на основании авторских эмпирических исследований, проведенных в 2017 г. и 2021 г., рассматривается динамика удовлетворенности молодежи г. Казани экологическими и социальными аспектами качества городской среды. Полученные данные свидетельствуют о том, что экологическая обстановка и состояние городской инфраструктуры сохраняют для молодого поколения свою значимость. При сохранении позитивных тенденций относительно большинства показателей, характеризующих экологическую ситуацию, выявлено снижение доли удовлетворенных состоянием водных объектов и санитарным состоянием города. Что касается городской инфраструктуры, то выявлено снижение удовлетворенности ее общим состоянием, а также такими составляющими как количество организованных автостоянок и количество спортивных объектов. Кроме того, в работе анализируются факторы, определяющие привлекательность для молодежи районов города, и выделяются наиболее важные мероприятия, направленные на улучшение качества городской среды. Based on the author's empirical research carried out in 2017 and 2021, the article examines the dynamics of satisfaction of young people in Kazan with the ecological and social aspects of the quality of the urban environment. The data obtained indicate that the ecological situation and the state of the urban infrastructure retain their importance for the younger generation. While maintaining positive trends in relation to most of the indicators characterizing the ecological situation, a decrease in the share of those satisfied with the state of water bodies and the sanitary state of the city was revealed. As for the state of the urban infrastructure, a decrease in satisfaction with its general state, as well as with such components as the number of organized parking lots and the number of sports facilities, was revealed. The work also analyzes the factors that determine the attractiveness of city districts for young people and highlights the most important measures aimed at improving the quality of the urban environment.
