Changes in acoustic measurements of vowel formants, vowel duration, voicing, manner of articulation, and place of articulation cues are discussed. Listener judgments of target words are presented. The present findings are related to previous case studies of speech changes with a multichannel cochlear implant [Tartter et al., J. Acoust. Soc. Am. 86, 2113–2121 (1989)] and single electrode stimulation [Leder et al., J. Acoust. Soc. Am. 79, 1967–1974 (1986)].

Neurofeedback (NF) is widely used for the treatment of ADHD, thus such ADHD cases will be reviewed in this study. As an introduction, a short overview of the definition of ADHD and Neurofeedback, as well as the history of neurofeedback in ADHD will be given. The main part of the paper will present a literature review of neurofeedback in ADHD while mentioning the effects of this treatment. Results and evaluation of NF applications among other treatments are to be discussed in the conclusion, showing that NF is quite promising on ADHD subjects.

Memory plays an important role, among others, on route planning and traffic signs recognition. In addition, visuospatial skills are crucial for vehicle’s road positioning along with the estimation of distances between vehicles, while attention is necessary for the accurate perception of on-road changes. The role of Neuropsychology is of critical importance for evaluating driving ability in the elderly, especially in the case of drivers with cognitive disorders, such as Mild Cognitive Impairment and Alzheimer’s Dementia. Regarding the driving competence of drivers with Mild Cognitive Impairment, in the majority of cases they are considered capable of driving. Although Alzheimer’s Dementia has a well-recognized and –described negative effec...

Identification of neurologist’s role when assessing fitness to drive of cognitively impaired individuals. We performed a systematic review of the guidelines/recommendations (G/Rs) regarding the evaluation of driving fitness of patients with mild cognitive impairment (MCI) and/or dementia. Emphasis was put on the neurological and neuropsychological aspects of the evaluation. Eighteen G/Rs were included in the review (9 national guidelines, 5 recommendation papers, 3 consensus statements, and 1 position paper). All G/Rs referred to drivers with dementia and 9/18 referred to drivers with MCI. A common approach among G/Rs is the initial trichotomization of patients in safe to drive, unsafe to drive, and undetermined cases, which are referred to a second-line evaluator. First-line evaluators are general practitioners in 10/18 G/Rs; second-line evaluators are neurologists in 7/18 G/Rs. Specific neuropsychological tests are proposed in 11/18 G/Rs and relative cut-off values in 7/18. The most commonly used tests are the MMSE, TMT, and CDT. A thorough neurological examination is proposed in only 1/18 G/R. Although extensive multi-disciplinary research has provided useful information for driving behavior of cognitively impaired individuals, we are still far from a widely accepted approach of driving ability evaluation in this increasing population. A comprehensive assessment from a multi-disciplinary team in which the neurologist plays a critical role seems to be required, although this has not yet been implemented in any G/Rs.

In this paper, we present the cognitive processes that are related to it, such as working memory, attention, inhibitory control, executive function, and processing speed. In addition, we refer to metacognitive skills and their role in controlling and regulating cognitive processes in order to improve children’s performance. Finally, we present a new taxonomy of skills, the pyramid of 8 levels, as well as their gradual development through the appropriate cognitive and metacognitive mechanisms. In this study, a holistic and multi-disciplinary approach is attempted by collecting and utilizing data from sciences such as cognitive psychology, neuropsychology, and philosophy. The research has led us to the 8 layers that underpin metacognition in preschoolers following the model of the hierarchical orga...

Their role is examined according to the educational perspectives that are explored in preschool settings including also their role in special preschool education. The domains of literacy, maths, cognitive & motor skills, creativity, communication and special education are investigated. Also, the beliefs of teachers about using games for teaching and learning are interviewed.

Twenty-seven individuals with amnestic mild cognitive impairment (MCI) and 26 healthy elderly drivers participated in a driving simulator study. After the driving assessment, participants were asked to self-evaluate their performance in comparison with what they considered as average for people of similar age and educational level. According to the applied mixed analysis of variance model, the MCI patients presented increased difficulties in estimating their driving performance to a greater extent in the rural environment in comparison with the urban condition. Our findings suggest that the ability of MCI patients to evaluate their driving performance accurately seems to be enhanced or compromised, depending on the number of cues available in their environment, suggesting that providing feedback may improve their metacognitive...

TC is an advanced cognitive activity that is both situation- and task-specific. The aim of the present study was the development of a brief, specialized instrument for TC assessment in patients with dementia. We developed a short tool consisting of four subtests, assessing the person's core functions which are required for TC: memory (orientation, autobiographical memory and realistic perception of beneficiaries), absence of serious psychopathology, knowledge of financial parameters (value of assets, everyday life products, bills), and intention (vignettes, theory of mind). For its validation, we examined 64 outpatients from the Cognitive Disorders/Dementia Unit, 2nd Department of Behavioral Neurology, University of Athens. The decision of the expert served as the gold standard for the evaluation of TC....

Recent researches support the view that the role of kindergarten in children’s progress is very important, as this age is sensitive for their future academic and social life. The use of mobile learning is recognized as a tool that can foster the knowledge and the experiences for this age and the support of specific areas according to the educational perspective. In this paper we try to give a brief overview of the most representative studies of the last decade (2005-2015), which focus on the skills that are explored in kindergarten and are supported by the mobile applications. The effectiveness of mobile learning in special preschool education is also explored.

Working memory -as one of the most important cognitive skills of human brain- comprises a system with specific functions with which the information from the external environment are being transferred, encoded, stored and retrieved. The present study is an attempt to explore which specific function of working memory is activated in order to decode each linguistic field of analysis. Furthermore, it features the current scientific achievements on the ICTs processes and tools, which exploit the cognitive skill of memory and they are applied in the assessment of difficulties in text comprehension, intervention and training of the language comprehension ability.

Our goal was to cover a gap in the literature and to explore the link between depressive symptoms and driving behavior in individuals with Mild Cognitive Impairment (MCI) through the use of a driving simulator experiment. Twenty-four individuals with MCI (Age: Mean = 67.42, SD = 7.13) and 23 cognitively healthy individuals (Age: Mean = 65.13, SD = 7.21) were introduced in the study. A valid driving license and regular car use served as main inclusion criteria. Data collection included a neurological/neuropsychological assessment and a driving simulator evaluation. Depressive symptomatology was assessed with the Patient Health Questionnaire (PHQ-9). Significant interaction effects indicating a greater negative impact of depressive symptoms in drivers with MCI than in cognitively healthy drivers were observed in the case of various driving indexes, namely average speed, a...

Up to date, few studies have addressed this topic in mild cognitive impairment (MCI) patients. The aim of the present study was to compare objective measures of performance with subjective perception of specific performance on cognitive tests and investigate differences in assessment between MCI patients and healthy elderly. Thirty-five participants diagnosed with MCI (women = 16, men = 19, mean age = 65.09 years ±SD = 7.81, mean education = 12.83 years ±SD = 4.32) and 35 control subjects similar in terms of age and education (women = 20, men = 15, mean age = 62.46 years ± SD = 9.35, mean education = 14.26 ± SD = 2.84) were examined with an extended battery of neuropsychological tests. After every test they were asked to self-evaluate their performance by comparing it to what they considered as average for people of their age and educational level. This self-ev...
