|| (2011-07-29) Cognitive distortions as predictor of antisocial behaviour in children|
Cate, E.A. ten
The aim of this study was to investigate the reliability and validity of the How I think Questionnaire (HIT- Q), adapted to children in the age of 7 to 9 years old. The main hypothesis was that children between 7 and 9 years old demonstrate some cognitive distortions and that these distortions are predictive of antisocial behaviour. A group of 156 children from the second (N= 75) and the third grade (N= 88) participated in the study. The results showed that the children showed on average a low p....................
|| (2013-01-01) Cognitive flexibility in Obsessive-Compulsive Disorder and Body Dysmorphic Disorder|
Research suggests that obsessive-compulsive disorder (OCD) and body dysmorphic disorder (BDD) share important characteristics. This has led to the proposition to add both disorders to a new DSM-5 category: ‘Obsessive-Compulsive Spectrum Disorders’. Although clinical and demographic characteristics suggest this overlap, neuropsychological theories explaining the obsessions and compulsions associated with both disorders are barely studied. One theory originating from OCD research is the cognit....................
|| (2010-01-01) Cognitive flexibility in pathological gamblers, an fMRI study|
Pathological gambling (PG) is a disorder in which people become preoccupied with gambling behaviour, despite the negative consequences. There is a high relapse rate under pathological gamblers and today’s treatment seems to be effective in only a small part of the population. Pathological gamblers show impairments on tasks that measure cognitive flexibility, which is the ability to switch between two rules. We assessed a task that measures cognitive flexibility, the switch task, on pathologica....................
|| (2013-01-01) Cognitive flexibility training for elderly : the effects on task switching.|
Healthy elderly show a decline in executive functioning. Executive functioning predicts quality of
daily living. Therefore, enhancement of executive control functions is desirable, e.g. by training.
Prior research suggests that executive function training that relies on cognitive flexibility by
switching between tasks induces transfer to executive function tasks. This study examined
whether 1) cognitive flexibility training (number of times switching during training) induced
improvement of ....................
|| (2014-01-01) Cognitive flexibility training in children with an autism spectrum disorder : short-term effects and rRelationship to tTheory of mMind|
Deficits in executive functioning (EF), including cognitive flexibility deficits, have been
suggested to be important in children with Autism spectrum disorders (ASDs). The main
goal of the study was to investigate the short-term effects of a computerized cognitive
flexibility training in children with ASD. Since previous studies showed that cognitive
flexibility and Theory of Mind (ToM) are related in children with ASD, this study also
investigated the role of ToM with respect to the cogni....................
|| (2016-02-09) Cognitive function in amyotrophic lateral sclerosis: Is the ECAS a valid instrument for screening cognitive function in ALS?|
The main goal of this study was to validate the Edinburg cognitive and behavioural ALS screen (ECAS) in a Dutch sample. The ECAS is a cognitive instrument developed especially for patients with Amyotrophic lateral sclerosis (ALS) that measures executive function, language, verbal fluency, memory and visuospatial functions (Abrahams et al., 2015). Up to 50% of ALS patients suffer from cognitive impairment, which is associated with a lower quality of life. In order to validate the ECAS, three goal....................
|| (2008-07-31) Cognitive functioning deficits in Borderline personality disorder|
Borderline Personality disorder (BPD) is characterized by unstable affect, behaviour, mood, interpersonal relationships and self-image. Several cognition deficits have been found in BPD patients, but the cognitive functioning profile is far from complete. This meta-analysis compares and discusses the results of neuropsychological studies of BPD and integrates them with neuroimaging/biological findings. A total of 16 studies compromising 809 participants on cognitive functioning in BPD patients w....................
|| (2015-05-01) Cognitive functioning in patients with auditory Charles Bonnet Syndrome|
Background: Hallucinations are related to impaired cognitive functioning in patients with Alzheimer’s disease, Parkinson’s disease, schizophrenia, but also in controls (patients without a neurologic or psychiatric diagnosis). The current study examined the difference in cognitive functioning between patients with hearing loss experiencing auditory hallucinations (auditory Charles Bonnet Syndrome) and patients with hearing loss without hallucinations (controls). Methods: 31 patients from depa....................
|| (2012-01-01) Cognitive functioning related to health-related quality of life in tumor patients.|
There is a paucity in research assessing the relation between cognitive status and health-related quality of life (HRQOL) of tumor patients. In this study cognitive functioning was measured by a neuropsychological testing battery and HRQOL was assessed by the SF-36 questionnaire in five tumor patient groups: high-grade glioma (N= 120), low-grade glioma (N= 221), meningioma (N= 90), non-small cell lung cancer (N= 150), and hematological malignancies (N= 100). Healthy controls were individually ma....................
|| (2013-08-30) Cognitive Load Measurement: Different instruments for different types of load?|
This study focused on the measurement of two types of cognitive load: intrinsic and extraneous load. In the past, a variety of measurement instruments have been used to indicate the overall cognitive load, but distinguishing between intrinsic and extraneous load remains difficult. Three different kinds of instruments to measure cognitive load were compared on what type of cognitive load they were able to measure: a subjective rating scale, a thinking aloud dual task and an eye tracker. Participa....................
|| (2013-01-01) COGNITIVE LOAD WHILE HAVING THE INTENTION TO DECEIVE|
A lot of research has been done on deception- and deception detection. We state that deception cannot be seen as a process of just a few moments, and thus cannot be reduced to just the lie(s) itself. We do weight the importance on another concept in deceptive behavior: the intention to deceive. It is likely that the intention to deceive characterize liars, but very few studies do actually attend to this likely process. We did examine this ‘intention to deceive’ in an experimental setting. Th....................
|| (2008-01-01) Cognitive models of strategy shifts in interactive behavior|
In this study, we use cognitive models to investigate how humans develop preferences for specific strategies in interactive behavior. In our case study, subjects show a shift in strategy, to strategies that are mostly based either on interaction with the environment or on memory. ACT-R 5 models are unable to show this effect. This is ascribed to its utility learning mechanism. We use ACT-R 6, which has a new utility learning mechanism. Results indicate that regular ACT-R 6 models (i.e., models w....................
|| (2002-01-01) Cognitive navigation modeling in robots|
This thesis addresses the problem of SLAM: simultaneous localization and mapping by robots in a dynamic environment. A multimodal approach using single-camera images and ultrasone range detectors on Pioneer-II robots is used. Kohonen self-organized maps are used to learn salient landmarks in the environment. Using odometry, it could be shown that the essential layout of the landmarks in the 2D plane can be reconstructed approximately using principal-component analysis on the odometry-distance ma....................
|| (2008-07-07) Cognitive poetics: hype or hope? A critical overview of cognitive approaches and their practical applications to literature|
Reijmersdal, Cécile van
In de scriptie wordt een overzicht gegeven van verschillende cognitieve benaderingen van literatuur. Er wordt kritisch gekeken naar de bruikbaarheid van de besproken theorieën en gezocht naar een manier om de empirische werkwijze van de cognitiewetenschap te verenigen met de dialectiek van de geesteswetenschappen. Theorieën van o.a. Reuven Tsur, Mark Turner, Richard Gerrig en Lisa Zunshine worden niet alleen kort uiteengezet, maar toegepast op een korte tekst, om zo het verschil met een hermen....................
|| (2013-01-01) Cognitive processes causing pupil dilation in a sequential multitasking experiment|
Certain cognitive processes are reflected in dilation of the human eye pupil. In ongoing research, it was found that the eye pupil dilated just before participants made a decision to switch between tasks during a sequential multitasking experiment. There are several possible explanations for this phenomenon. Two of these explanations involve making a decision. The pupil size increase could be caused by a `pure' decision, or by a decision which involves deliberate planning. The current research i....................
|| (2013-01-01) Cognitive processes causing pupil dilation in a sequential multitasking experiment|
Zwan, P.T. van der
Changes in the size of the human eye pupil can be caused by various cognitive processes. Recent studies have revealed that the eye pupil dilates just before switching to a secondary task during a sequential multitasking experiment. One way to explain the pupil dilation is the planning involved in the decision to switch. In the experiment, participants were asked to play several games of Concentration, consisting of cards with linear equations to be solved. Participants had to switch to the secon....................
|| (2012-10-01) Cognitive Processes in Reading Comprehension: An ERP study on the maintenance of global coherence in discourses|
Reading comprehension is a dynamic process which is influenced by a range of text characteristics and individual characteristics (Van den Broek, 1994). An important text characteristic is coherence, a measure of the interconnectedness of information within a text, which can be assessed locally and globally. This study was intended to conceptually replicate previous research using event-related potentials (ERPs) to investigate the maintenance of global coherence. ERPs were computed for critical w....................
|| (2007-01-01) Cognitive Profile in Rubinstein-Taybi Syndrome.|
Molen, M.J.W. van der
Mutations in the gene encoding CREB-binding protein (CBP) or the related P300 gene cause Rubinstein-Taybi syndrome (RTS), a rare form of MR with distinctive physical signs. CBP is involved in transcriptional regulation through CREB (cAMP response element-binding), which plays an important role in long-term synaptic plasticity, as well as in epigenetic regulation of gene expression. Several genetically modified mouse-models, mimicking the mutations seen in RTS, show deficiencies in synaptic plast....................
|| (2010-01-01) Cognitive profile of children with Frontal Lobe Epilepsy|
Introduction: Epilepsy is the most common neurological disorder in childhood. Frontal Lobe Epilepsy (FLE) is the second most common type of partial epilepsy. Comorbid disorders such as cognitive impairment and educational underachievement are frequently described in epilepsy.
Method: To explore whether a characteristic cognitive profile exist for FLE, the performance of 79 children with FLE on intelligence and neuropsychological tests and scores on behavioural questionnaires were analysed. Age....................

This study examined cognitive profiles in a 2-wave study, two and three years of age,
consisting of 1340 preschoolers. The cognitive profiles consisted of a constellation of four
cognitive components; phoneme detection, vocabulary, visual working memory and visual
attention.Four separate cognitive profiles were found; the high ability profile, the high/low
ability profiles characterized by high ability on all but visual working memory, the medium
ability cognitive profile, and the low ability co....................
|| (2009-06-30) Cognitive Radio Design: An SDR Approach: |
Doost Mohammady, R.
Cognitive Radios are currently a big challenge for the telecommunications industry. Many efforts are in progress to make communication radio systems as adaptive as possible such that they are aware of their environment and they are self configurable. An ultimate adaptive radio with the specified features is used to be called a Cognitive Radio. A cognitive radio can sense its operating environment's conditions and it is able to reconfigure itself and to communicate with other counterparts based o....................
|| (2009-07-15) Cognitive Radio in a Regulatory Environment: |
It has been widely recognized that the valuable, yet finite radio spectrum is being underutilized by licensed systems both spatially and temporally. To realize a more efficient use of this valuable resource, secondary spectrum usage by cognitive radios is being considered. Cognitive Radio is a paradigm for wireless communication in which either a network or a wireless node changes its transmission or reception parameters to communicate effectively while avoiding interference to licensed users. T....................
|| (2013-01-01) Cognitive radio: comparing cross-correlators|
Because the free bands in the electromagnetic spectrum are
becoming scarce, numerous techniques have been developed
throughout the years to increase capacity. But studies have shown
that when the activity on the band is measured a lot of the segments
are unused. The concept of Cognitive Radio is that it
can intelligently detect and utilize the unused segments when
available, without interfering primary users.
Sensing the spectrum for spectrum holes is one of the key
function of a cogniti....................
