Implicit approach-avoidance tendencies can be measured by the approach-avoidance task (AAT). The emergence of mobile variants of the AAT enable its use for both in-the-lab and in-the-field experiments. Within the food domain, use of the AAT is concentrated in research on eating disorders or healthy eating and is seldom used as an implicit...

Background. A Head Mounted Display (HMD) is unlike all other displays fixed to the head, making eye movements the sole option to scan the display. While the largest saccades easily exceed 50 deg (Collewijn et al., 1988), naturally occurring saccades typically stay within 15 degrees (Adler & Stark, 1975). While attractive for many applications, a...

Background: Botulinum neurotoxin A (BoNT-A) is a highly neurotoxic drug and frequently used in patients. Knowledge on the optimal way of administration of BoNT-A and its subsequent distribution is still rather limited. An accurate method for monitoring these processes might be the use of radiolabelled BoNT-A. In this paper, we report our...

The effect of different workstations, conventional and dynamic, on different types of performance measures for several different office and computer based task was investigated in this research paper. The two dynamic workstations assessed were the Lifespan Treadmill Desk and the RightAngle LifeBalance Station, and the two conventional...

Background. Due to shortcomings in the design, no source-specific exposure-effect relations are as yet available describing the effects of noise on children's cognitive performance. This paper reports on a study investigating the effects of aircraft and road traffic noise exposure on the cognitive performance of primary schoolchildren in both...

The majority of studies investigating interactions between vision and touch have typically explored single events, presenting one object at a time. The present study investigates how tactile-visual interactions affect competition between multiple visual objects in more dynamic cluttered environments. Participants searched for a horizontal or...

Participants performed an attentional blink (AB) task including digits as targets and letters as distractors within the visual and auditory domains. Prior to the rapid serial visual presentation, a visual or auditory prime was presented in the form of a digit that was identical to the second target (T2) on 50% of the trials. In addition to the ...

Searching for an object within a cluttered, continuously changing environment can be a very time-consuming process. The authors show that a simple auditory pip drastically decreases search times for a synchronized visual object that is normally very difficult to find. This effect occurs even though the pip contains no information on the location...

To evaluate the neurobehavioral effects of hydrocarbon solvents and to establish a working model for extrapolating animal test data to humans, studies were conducted which involved inhalation exposure of rats and humans to white spirit (WS). The specific objectives of these studies were to evaluate the behavioral effects of exposure to WS in...

We developed a fast and efficient method to derive and apply a natural colour mapping for night-time imagery from multi-band sensors. The colour mapping is derived from the combination of a multi-band image and a corresponding natural colour reference image. The mapping optimizes the match between the multi-band image and the reference image,...

During night-time driving hazardous objects often appear at mesopic light levels, which are typically measured using light meters with a spectral sensitivity that is only valid for photopic light levels. In order to develop suitable mesopic models a target detection experiment was performed in a driving simulator. While subjects drove along a...

Background: Brain serotonin function is thought to promote sleep regulation and cognitive processes, whereas sleep abnormalities and subsequent behavioral decline are often attributed to deficient brain serotonin activity. Brain uptake of the serotonin precursor tryptophan is dependent on nutrients that influence the availability of tryptophan...

PCBs are known for their neurotoxic properties, especially on the developing brain. To increase insight into the neurotoxic effects of PCB exposure, the authors studied the effects of perinatal exposure to environmental levels of these compounds on different neuropsychological domains. In 9-year-old children of the Rotterdam PCB-dioxin cohort,...

Objective: To test a new method (cross-correlation baroreflex sensitivity, xBRS) for the computation of time-domain baroreflex sensitivity on spontaneous blood pressure and heart interval variability using the EUROBAVAR data set. Methods: We applied xBRS to the 42 records in the EUROBAVAR data set, obtained from 21 patients in the lying and...

Two experiments investigated effects of expectations on eye fixations and responses to expected and unexpected information in a laboratory setting. Stimulus fixation and manual responses to predefined targets among distractors were measured in a dynamic environment shown on a monitor. Participants were part of either a predictable condition ...

Brain serotonin (5-HT) synthesis is controlled by nutrients that influence the availability of plasma tryptophan (Trp) as compared with the sum of the other large neutral amino acids (LNAA; Trp:LNAA). Alcohol consumption is found to change mood and performance and this might well be due to alterations in the plasma Trp:LNAA ratio and brain 5-HT....

This study examined motor control in 61 early and continuously treated patients with phenylketonuria (PKU) and 69 control participants, aged 7 to 14 years. The pursuit task demanded concurrent planning and execution of unpredictable movements, whereas the tracking task required a highly automated circular movement that could be planned in...

Fifty-seven 7-14-year-old early- and continuously treated phenylketonuria (PKU) patients and 65 matched controls performed a sustained attention task. PKU patients with plasma phenylalanine (phe) levels higher than 360 μmol/l at the time of testing exhibited, compared to controls, lower speed of information processing, a lower ability to inhibit...
