Especially, the cognitive symptoms offer useful methodological approach for comparative studies using spatial navigation tasks in both, schizophrenia patients and animal models of cognitive deficit in schizophrenia. In order to demonstrate the deficit of spatial cognition in schizophrenia and to test the validity of pharmacological model, we designed two virtual tasks inspired by previous animal research: the virtual Morris water maze and Carousel maze. The newly-designed tasks require the tested subject to navigate toward several hidden goal positions placed on the floor of an enclosed stable arena or on a rotating arena. Data obtained in a group of schizophrenia patients and matched group of healthy volunteers show cognitive impairment in first episodes of schizophrenia using both, standardized neurocognitive methods and newly-developed virtual tests. The virtual test batteries show different involvement of navigation strategies and different level of impairment in schizophrenia patients. These findings indicate usefulness of these virtual methods in future cognitive remediation. Despite the fact, that both virtual tasks test spatial navigation towards hidden goal, obtained results are divided into partly different clusters using PCA, while performance parameters measured in the stable arena form a cluster mostly with tests of memory and executive functions; the rotating arena seems to be more related to performance tests dependent on timing, psychomotor speed and mental flexibility.","PeriodicalId":194703,"journal":{"name":"2015 International Conference on Virtual Rehabilitation (ICVR)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130349672","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}

Benefits of using a virtual environment can range from increasing the participant's motivation to the ease of adapting extrinsic feedback for optimizing motor learning. In the proposed research, children with CP will be randomly allocated to one of three groups: no additional feedback, continuous feedback and faded feedback. For all groups, upper-limb motor training will be done in a virtual environment using the Jintronix virtual reality system. Motor improvements will be evaluated after an 8 hour training intervention and motor learning will be evaluated after one month. Transfer of motor gains to performance of a similar upper-limb task will also be used to assess learning. Findings from this research will provide crucial information on which frequency of feedback should be used to optimize motor learning and upper-limb rehabilitation in children with CP.","PeriodicalId":194703,"journal":{"name":"2015 International Conference on Virtual Rehabilitation (ICVR)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134574204","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}

{"title":"The benefits of emotional stimuli in a virtual reality cognitive and motor rehabilitation task: Assessing the impact of positive, negative and neutral stimuli with stroke patients","authors":"A. L. Faria, M. Cameirão, T. Paulino, S. Bermúdez i Badia","doi":"10.1109/ICVR.2015.7358584","DOIUrl":"https://doi.org/10.1109/ICVR.2015.7358584","url":null,"abstract":"VR-based methods for stroke rehabilitation have mainly focused on motor rehabilitation, but there is increasing interest towards the integration of cognitive training for providing more ecologically valid solutions. However, more studies are needed, especially in the definition of which type of content should be used in the design of these tools. One possibility is the use of emotional stimuli, which are known to enhance attentional processes. According to the Socio-emotional Selectivity Theory, as people age, this emotional salience arises for positive and neutral, but not for negative stimuli. Conversely, negative stimuli can be better remembered. In this study, we investigated the impact of using emotional stimuli with positive, negative and neutral valence in a VR cognitive and motor attention task. Ten stroke patients participated in a within-subjects experiment with four conditions based on the type of stimuli: abstract (control condition), positive, negative and neutral. The main task consisted of finding a target stimulus, shown for only two seconds, among fourteen neutral distractors. Eye movements were recorded with an eye-tracking system to investigate differences between conditions and in search patterns. Subsequently, a recall task took place and the patients had to identify all the target images among a valence-matched number of distractors. Our results corroborate the attention salience effect of positive and neutral stimuli in the VR task performance. Although we found no statistically significant differences between conditions in the recall task, there was a trend for recalling more negative images. This negative advantage comes at the expense of significantly more wrongly identified images/false memories for negative stimuli. Finally, we performed an analysis in which we relate performance scores with well-established cognitive assessment instruments, which supportsG the use of this approach both for assessment and rehabilitation purposes.","PeriodicalId":194703,"journal":{"name":"2015 International Conference on Virtual Rehabilitation (ICVR)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131907686","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}
