Eighteen schizophrenia patients and 15 healthy participants undertook a recognition memory task. The stimuli consisted of pairs of words either semantically related or unrelated to a given category name (context). During encoding, both groups exhibited an N400 external semantic coherence effect. Healthy controls also showed an N400 internal semantic coherence effect, but this effect was not present in patients. At test, related stimuli were accompanied by an FN400 old/new effect in both groups and by a parietal old/new effect in the control group alone. In the patient group, external semantic coherence effect was associated with FN400, while, in the control group, it was correlated to the parietal old/new effect. Our results indicate that schizophrenia patients can process the contextual information at encoding to enhance familiarity process for related stimuli at test. Therefore, cognitive rehabilitation therapies targeting the implementation of semantic encoding strategies can mobilize familiarity which in turn can overcome the recollection deficit, promoting successful episodic memory performance in schizophrenia patients.</p>","PeriodicalId":45388,"journal":{"name":"Schizophrenia Research and Treatment","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1155/2018/8501973","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"35911749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The questions were, what are the experiences around parents' informal care activities and responsibilities and how do parents construct and manage their caring responsibility and with what consequences? Semistructured in-depth interviews were conducted (16 hours of recorded material) with eight parents who were all members of the Interest Association for Schizophrenia (Intresseföreningen för Schizofreni (IFS)) in Sweden. A mixed hermeneutic deductive and inductive method was used for the interpretation of the material. The parents endow their informal caring responsibility with meaning of being a good, responsible, and accountable parent with respect to their social context and social relationships as well as with respect to the psychiatric care representatives. In this tense situation, parents compromise between elements of struggle, cooperation, avoidance, and adaption in their interaction with the world outside, meaning the world beyond the care provision for their child, as well as with the world inside themselves.","PeriodicalId":45388,"journal":{"name":"Schizophrenia Research and Treatment","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2016-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86381886","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}
