Yayın Turkish sign language adaptation of the Turkish Health Literacy Scale-32(NLM (Medline), 2022-09-15) Ataseven Bulun, Mehtap; Çepni, Selden; Ermez, YusufSign language speakers are at a disadvantage in terms of health literacy due to the lack of health education materials in sign languages. Deaf and hard of hearing (DHH) individuals are excluded from health literacy research due to the lack of measurement tools in their language of excellent f luency. This study aims to provide the literature with a tool that allows the measurement of health literacy among DHH individuals. The Turkish Health Literacy Scale (THLS)-32 was translated into Turkish Sign Language (TSL). After the THLS-32 was translated into TSL in video format, it was tested for validity and reliability. The translated version of the scale was administered to participants from a DHH association in Turkey who are f luent in TSL. Subsequently, a study was conducted with 207 DHH individuals. The study group was assessed in terms of their mean index scores and evaluated to have “limited health literacy” according to the THLS-32 classification. We conclude that the THLS-32 in TSL is suitable to measure health literacy in DHH individuals and to assess the impact of the health education system.Yayın The function of regressions in reading: Backward eye movements allow rereading(Springer, 2013-01) Booth, Robert William; Weger, Ulrich W.Standard text reading involves frequent eye movements that go against normal reading order. The function of these "regressions" is still largely unknown. The most obvious explanation is that regressions allow for the rereading of previously fixated words. Alternatively, physically returning the eyes to a word's location could cue the reader's memory for that word, effectively aiding the comprehension process via location priming (the "deictic pointer hypothesis"). In Experiment 1, regression frequency was reduced when readers knew that information was no longer available for rereading. In Experiment 2, readers listened to auditorily presented text while moving their eyes across visual placeholders on the screen. Here, rereading was impossible, but deictic pointers remained available, yet the readers did not make targeted regressions in this experiment. In Experiment 3, target words in normal sentences were changed after reading. Where the eyes later regressed to these words, participants generally remained unaware of the change, and their answers to comprehension questions indicated that the new meaning of the changed word was what determined their sentence representations. These results suggest that readers use regressions to reread words and not to cue their memory for previously read words.Yayın Analyzing language ability in first-episode psychosis and their unaffected siblings: a diffusion tensor imaging tract-based spatial statistics analysis study(Elsevier Ltd, 2024-11) Çabuk, Tuğçe; Şahin Çevik, Didenur; Çakmak, Işık Batuhan; Yılmaz Kafalı, Helin; Şenol, Bedirhan; Avcı, Hanife; Karlı Oğuz, Kader; Toulopoulou, TimotheaSchizophrenia (SZ) is a highly heritable mental disorder, and language dysfunctions play a crucial role in diagnosing it. Although language-related symptoms such as disorganized speech were predicted by the polygenic risk for SZ which emphasized the common genetic liability for the disease, few studies investigated possible white matter integrity abnormalities in the language-related tracts in those at familial high-risk for SZ. Also, their results are not consistent. In this current study, we examined possible aberrations in language-related white matter tracts in patients with first-episode psychosis (FEP, N = 20), their siblings (SIB, N = 20), and healthy controls (CON, N = 20) by applying whole-brain Tract-Based Spatial Statistics and region-of-interest analyses. We also assessed language ability by Thought and Language Index (TLI) using Thematic Apperception Test (TAT) pictures and verbal fluency to see whether the scores of these language tests would predict the differences in these tracts. We found significant alterations in language-related tracts such as inferior longitudinal fasciculus (ILF) and uncinate fasciculus (UF) among three groups and between SIB and CON. We also proved partly their relationship with the language test as indicated by the significant correlation detected between TLI Impoverished thought/language sub-scale and ILF. We could not find any difference between FEP and CON. These results showed that the abnormalities, especially in the ILF and UF, could be important pathophysiological vulnerability indexes of schizophrenia. Further studies are required to understand better the role of language as a possible endophenotype in schizophrenia with larger samples.
