Multisensory integration (MSI) is the integration by the brain of environmental information acquired through more than one sense. Accurate MSI has been shown to be a key component of successful aging and to be crucial for processes underlying activities of daily living (ADLs). Problems in MSI could prevent older adults (OA) to age in place and...

In this cross-sectional study associations were examined between eight shift schedule characteristics with shift-specific sleep complaints and need for recovery and generic health and performance measures. It was hypothesized that shift schedule characteristics meeting ergonomic recommendations are associated with better sleep, need for recovery...

High heart rate variability (HRV) and low skin conductance level (SCL) have been associated with low levels of stress. Biofeedback - providing an individual with online information about his or her own physiological state – may help to change these signals in the desired direction and therewith improve an individual’s physical or mental...

In driver behaviour research there is considerable focus on distraction caused by specific external systems, such as navigation systems or mobile telephones. However, it is not clear whether self-paced actions such as daydreaming have the same negative effects on driving behaviour. In a driving simulator study, the effects of an internal...

When using brain–computer interfaces (BCIs) to control a game, the BCI may have to compete with gaming tasks for the same perceptual and cognitive resources.We investigated: 1) if and to what extent event-related potentials (ERPs) and ERP–BCI performance are affected in a dual-task situation; and 2) if these effects are an area function of the...

While a BCI usually aims to provide an alternative communication channel for disabled users who have difficulties to move or to speak, we focused on BCIs as a way to retrieve and use information about an individual’s cognitive or affective state without requiring any effort or intention of the user to convey this information. Providing only an...

We here introduce a new experimental paradigm to induce mental stress in a quick and easy way while adhering to ethical standards and controlling for potential confounds resulting from sensory input, body movements and behavior of people involved in conducting the experiment. In our Sing-a-Song Stress Test, participants are presented with...

We examined to what extent we can distinguish between ‘real-life’ stressed and relaxed participants on the basis of heart rate (HR), heart rate variability (HRV) and skin conductance level (SCL) as measured during rest. Physiological and subjective measures were compared between individuals that were to undergo eye laser surgery and a control...

Low neuroticism and high extraversion seem to be predictors for people performing well during and after extremely stressful circumstances. Here we investigate whether these personality factors are linked to stress sensitivity. Stress was induced through negative feedback on gaming performance and stress sensitivity was determined as the...

User-adaptive visualization aims to adapt visualized information to the needs and characteristics of the individual user. Current approaches deploy user personality factors, user behavior and preferences, and visual scanning behavior to achieve this goal. We argue that neurophysiological data provide valuable additional input for user-adaptive...

The defense is confronted with a high competition on the labor market and a substantial scarcity of personnel. If we are able to enhance and maintain resilience and performance of personnel by proper selection procedures or mental training we expect to increase the return on investment of military education, training and operation, that is:...

Event-related potential (ERP) based brain-computer interfaces (BCIs) employ differences in brain responses to attended and ignored stimuli. When using a tactile ERP-BCI for navigation, mapping is required between navigation directions on a visual display and unambiguously corresponding tactile stimuli (tactors) from a tactile control device:...

The ability to continuously monitor workload in a real-world environment would have important implications for the offline design of human machine interfaces as well as the real-time online improvement of interaction between humans and machines. The present study explored the usefulness of combining electroencephalography (EEG) with the newer...

De publicatie is een combinatie van de resultaten van TNO projecten over crisiscommunicatie en zelfredzaameheid van burgers. Wat doe je als er in je omgeving iets gebeurt? Een overstroming, een opstootje of een ongeluk? Of als de stroom langdurig uitvalt, gas of water afgesloten raken in een strenge winter? En wat als er in je huis of kantoor...

Background The purpose was, first, to evaluate changes in health-related quality of life (HRQL) in a cohort of very low birth weight (VLBW; <1500 g.) or very preterm (< 32 weeks of gestation) children between ages 14 and 19, and second, to identify correlates of HRQL at age 19. Methods HRQL was assessed using the Health Utilities Index Mark 3 ...

How can you tell whether someone working or gaming is mentally taxed too high or too low? In collaboration with Noldus IT (Wageningen) and the FC Donders Institute (Nijmegen), TNO designed and conducted an experiment to measure mental load through brain signals. 35 participants performed a computer task that varied in difficulty. Our classifiers...

Previous studies indicate that both EEG spectral power (in particular the alpha and theta band) and ERPs (in particular the P300) can be used as a measure of mental work or memory load. We compare their ability to estimate workload level in a well-controlled task. In addition, we combine both types of measures in a single classification model to...

Giving direct feedback on a mental state is common practice in motor imagery based brain-computer interfaces (BCI), but has not been reported for those based on eventrelated potentials (ERP). Potentially, such feedback could allow the user to adjust his strategy during a running trial to obtain the required response. In order to test the...
