مقايسه يادگيري حركتي ضمني و يادگيري حركتي صريح در بيماران مبتلا به اسكيزوفرني

Comparison of implicit motor learning and explicit motor learning in patients with schizophrenia

مقدمه و اهداف نقص در حوزه هاي مختلف شناختي و اجرايي همچون مسيرهاي دخيل در يادگيري حركتي در بيماران اسكيزوفرني تا حدودي مشهود است. هدف از پژوهش حاضر بررسي مقايسه دو نوع يادگيري حركتي ضمني و يادگيري حركتي صريح در بيماران اسكيزوفرني بود. مواد و روش ها مطالعه حاضر از نوع پس رويدادي (مقايسه اي) است. جامعه پژوهش حاضر شامل بيماراني با تشخيص اسكيزوفرنيا (بين سنين 25 تا 40 سال) در مركز توانبخشي بهروان و بيمارستان شهيد زارع شهر ساري بودند. نمونه پژوهش حاضر شامل 35 فرد مبتلا به اسكيزوفرني در دو گروه يادگيري صريح (18 نفر) و يادگيري ضمني (17 نفر) بودند كه به صورت نمونه گيري در دسترس (آسان) انتخاب شدند. جمع آوري داده ها با استفاده از نرم افزار سنجش SRT (Serial Reaction Time Task) صورت گرفت. براي تجزيه و تحليل داده ها از نرم افزار SPSSنسخه 16 و آزمون هاي كالموگروف اسميرنوف و يومان ويتني استفاده شده است.    يافته ها نتايج حاصل از پژوهش حاضر نشان داد كهبين دو گروه از بيماران اسكيزوفرنيا يادگيري حركتي ضمني و حركتي صريح از نظر زمان پاسخ در روز اول در دو بلاك اول و هشتم تفاوت معناداري وجود نداشت (05/0

Background and Aim: Deficits in various areas such as pathways involved in motor learning and cognitive performance in schizophrenia patients is somewhat evident. The aim of the present study was to compare two types of implicit motor learning and explicit motor learning in patients with schizophrenia.Materials and methods: This study was retrospective (comparison). The present research community, including those with a diagnosis of schizophrenia (aged 25 to 40 years) by a psychiatrist at a rehabilitation center and hospital Behravan martyr farmers in Sari City. The study sample consisted of 35 patients with schizophrenia in explicit learning group (n = 18) and implicit learning (n = 17) who were selected by convenience sampling. Software for data collection to measure the SRT (serial reaction time task) was used. To analyze the data using SPSS version 16 and Whitney U test with Kalmvgraf and Smirnov were used.Results: The results of this study showed that the two groups of patients with schizophrenia implicit and explicit motor learning the response time for the first day and the eighth was not statistically different in the two first blog (P> 0/05).Also, the number of errors on the first day and changes in responsetime were not significantly different between the two groups of patients with implicit motor learning and explicit motor learning schizophrenia (P> 0/05). But the number of errors in blogs, the blog eighth of first day and the second blog of second day, there weresignificantly different between explicit and implicit motor learning schizophrenia (P= 0/04).Conclusion: The study found that patients with schizophrenia implicit motor learning in terms of learning were a little weaker than their counterparts did in explicit motor learning.
