Накратко на български

Двуезичният контрол върху превключването между езици се анализира чрез сравнение между младите и възрастните хора в различни ситуации. Това помага да се разбере как възрастта влияе върху когнитивните процеси и невронните механизми при използването на повече от един език.

Cognition, ageing, and bilingualism: Investigating age-related changes in bilingual language switching and use.

Over half of the European population speaks a second language. In an ageing society, it is thus important to understand how younger and older adults use multiple languages. The main aim of this project was to assess bilingual language control and switching in younger and older adults. Bilinguals need to monitor their surroundings to choose a language, ensure that they speak that language and not their other language, and sometimes switch between languages. Exactly how they achieve this, however, depends on the language context. Most previous work on bilingual language control has focused on more demanding contexts, for example by instructing bilinguals which language to use and when to switch. In bilingual societies such as the Basque Country (where this research was carried out), however, it is common for bilinguals to freely switch between their languages. The current research therefore focused on the role of context. The main questions assessed in this project were: 1. How do bilinguals use their languages in different interactional contexts? 2. How does age affect bilingual language control? 3. How does bilingual language control relate to cognitive control? 4. What are the neural mechanisms underlying bilingual language control?

Цел на проекта

Older adults show difficulties with bilingual language processing and switching compared to younger adults. For example, they need more time to switch between languages and show more cross-language intrusions. Language problems have not only been found for healthy older adults, but also in patients with dementia and Parkinson’s disease. Language deterioration could be used as an early disease marker to improve diagnosis. However, the exact nature of bilingual language problems in healthy older adults needs to be studied first. Besides language deficits, older age has also been associated with deficits on executive control tasks (e.g., inhibition and switching tasks). While executive control is argued to be needed during (bilingual) language production, it is unclear how the two relate in older adults. Although some studies have found similarities between language and cognitive control, others found deviating patterns. The proposed project therefore has two main aims:1.Examine language switching and use in younger and older adults.2.Investigate the relation between language and cognitive control.We will investigate these questions in multiple experiments using behavioural and neuroimaging techniques. Language switching will be measured in picture-naming tasks eliciting switching in a cued or voluntary manner. Cross-language intrusions will be examined in a verbal fluency task. Participants will furthermore complete several executive control tasks (e.g., colour-shape switching task and Simon task). Besides comparing younger and older adults, we will also examine effects of language proficiency and switching context. In an fMRI study, we will investigate whether effects of age on neuronal mechanisms are similar for language and executive control. Together, these experiments will allow us to assess the mechanisms behind bilingual language switching and executive control in younger and older adults.
