Although some reasons for it might be ideological, variability in sampling procedures and experimental design represent potential sources of inconsistency among studies. In this paper, we contend that bilingualism renders the extra-years of life of an increasingly long-lived population cognitively healthy, but only under specific conditions such as continuous practice and immersion in bilingual environments. We thus disagree with some authors’ recommendation that bilingualism be removed from consideration as a neuroprotective factor. We suggest, at the same time, that bilingualism should not be treated as axiologically superior to other environmental measures that promise to contrast the progressive loss of functional independence with increasing age. We conclude by emphasizing the need to evaluate the protective effects of L2-learning on the aging brain in a multimodal intervention perspective, thereby dissociating the effects of bilingualism from those of other cognitively stimulating factors.","PeriodicalId":187438,"journal":{"name":"Bi-/Multilingualism and the Declining Brain","volume":"51 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128872541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this\u0000 aim, the study explored the performance of pre-symptomatic and early-stage HD patients in two experimental tasks meant to elicit\u0000 cross-language interference and language inhibition, including a Stroop task and a language switching task. The results revealed\u0000 dissociations between these two mechanisms, indicating that language activation or inhibition is related to HD pathology while\u0000 cross-language interference is not. Switch costs in HD patients were greater than controls in low-demand control conditions of\u0000 language switching (longer preparation time), while Stroop effects were similar between the two groups of participants. This\u0000 result was interpreted as a difficulty in overcoming the excessive inhibition applied to non-target language. The BLC processes\u0000 related to the striatum and subcortical structures are discussed.","PeriodicalId":187438,"journal":{"name":"Bi-/Multilingualism and the Declining Brain","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124623804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
