van Baardewijk, J.U. (author), Agarwal, S. (author), Cornelissen, A.S. (author), Joosen, M.J.A. (author), Kentrop, J. (author), Varon, C. (author), Brouwer, A.M. (author)Early detection of exposure to a toxic chemical, e.g., in a military context, can be life-saving. We propose to use machine learning techniques and multiple continuously measured physiological signals to detect exposure, and to identify the chemical agent. Such detection and identification could be used to alert individuals to take appropriate...article 2021

Bottenheft, C. (author), Brouwer, A.M. (author), Stuldreher, I. (author), Groen, E. (author), van Erp, J. (author)Effects of stressors on cognitive task performance have primarily been studied in isolation, and little is known about the combined effects of two or more stressors. This study examined how a metabolic stressor (skipping breakfast) and a sensory stressor (noise) affect cognitive task performance in isolation and combined. In addition to...article 2021

Kaneko, D. (author), Hogervorst, M. (author), Toet, A. (author), Erp. J.B.F. van, (author), Kallen, V. (author), Brouwer, A.M. (author)Probing food experience or liking through verbal ratings has its shortcomings. We compare explicit ratings to a range of (neuro)physiological and behavioral measures with respect to their performance in distinguishing drinks associated with different emotional experience. Seventy participants tasted and rated the valence and arousal of eight...article 2019

Brouwer, A.M. (author), Stuldreher, I.V. (author), Thammasan, N. (author)Monitoring directed auditory attention in groups can be helpful in a range of contexts. Concurrent change in physiological variables across multiple listeners (physiological synchrony – PS) may be a suitable marker of attentional focus as caused by shared affective or cognitive processes. We here determine PS for EEG (electroencephalography),...conference paper 2019

Friedman, D. (author), Brouwer, A.M. (author), Nijholt, A. (author)In principle, brain-computer interfaces (BCIs) hold the promise for being the ultimate intelligent interfaces - what could surpass an interface that is able to interpret your thoughts and preferences, in real time, and behave accordingly? In practice, it is still not quite clear if and how BCIs can contribute to or replace existing interaction...conference paper 2017

Brouwer, A.M. (author), Snelting, A. (author), Jaswa, M. (author), Flascher, O. (author), Krol, L. (author), Zander, T. (author)We examined physiological responses to behavior of an Adaptive Cruise Control (ACC) system during real driving. ACC is an example of automating a task that used to be performed by the user. In order to preserve the link between the user and an automated system such that they work together optimally, physiological signals reflecting mental state...conference paper 2017

(author)While brain signals potentially provide us with valuable information about a user, it is not straightforward to derive and use this information to smooth man-machine interaction in a real life setting. We here propose to predict head rotation on the basis of brain signals in order to improve images presented in a Head Mounted Display (HMD)....conference paper 2017

Brouwer, A.M. (author), van Erp, J.B.F. (author), Heylen, D. (author), Jensen, O. (author), Poel, M. (author)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...conference paper 2013

Coffey, E.B.J. (author), Brouwer, A.M. (author), Wilschut, E.S. (author), van Erp, J.B.F. (author), TNO Defensie en Veiligheid (author)Recent advances in non-invasive brain-machine or brain-computer interfaces (BMIs/BCIs) have demonstrated that humans can control computers or simple robotic devices using only brain signals. These successes have lead to the suggestion that BMIs could significantly improve the safety and efficiency of space operations. Electroencephalography (EEG...article 2010

Raymann, R.J.E.M. (author), Swaab, D.F. (author), Van Someren, E.J.W. (author), TNO Defensie en Veiligheid (author)With ageing, an increasingly disturbed sleep is reported as a significant complaint affecting the health and well-being of many people. The available treatments for sleep disturbance have their limitations, so we have adopted a different approach to the improvement of sleep. Since in animal and human studies skin warming has been found to...article 2008

Markus, C.R. (author), Jonkman, L.M. (author), Lammers, J.H.C.M. (author), Deutz, N.E.P. (author), TNO Kwaliteit van Leven (author)Brain serotonin function has been implicated in the control of sleep and sleep related memory dysfunctions are attributed to deficient brain serotonin activity. Depletion of the serotonin precursor tryptophan reduces brain serotonin function and is found to cause sleep abnormalities and cognitive decline. We hypothesized that enhancing pre-sleep...article 2006

Smulders, F.T.Y. (author), Kenemans, J.L. (author), Schmidt, W.F. (author), Albert, K. (author), TNO Human Factors Research Institute (author)Twelve young and 11 elderly men (mean ages 21.1 and 70.1) performed a choice-reaction time (RT) task in which stimulus degradation and stimulus- response (S-R) compatibility were manipulated. The extant literature has suggested that the effects of age on RT are usually augmented (multiplicative) in more difficult task conditions, but also that...article 1999
