Juan Carlos Castro-Palacio, Pedro Fernández-de-Córdoba, J. M. Isidro, Sarira Sahu, Esperanza Navarro-Pardo
2021 Symmetry  
Based on the recent evidence of correlations between the reaction time series to visual stimuli produced by different individuals within a group, we go beyond and propose a Physics-inspired model to represent  ...  the reaction time data of a coetaneous group of individuals.  ...  We sincerely acknowledge the psychologists from the Interdisciplinary Modelling Group InterTech (, accessed on 25 October 2020) who participated in the collection of experimental data  ...

Brain reaction times: Linking individual and collective behaviour through Physics modelling [article]

Juan Carlos Castro-Palacio, Pedro Fernández de Córdoba, J. M. Isidro, Esperanza Navarro-Pardo
2019 arXiv   pre-print
Thus, we are able to know about the behaviour of a single individual in relation to the coetaneous group to which they belong and through the application of a physical law.  ...  We will focus on interpreting the reaction times (RTs) of a group of individuals rather than a single person's RT, which is relevant for the different contexts of social sciences.  ...  The psychologists from the Interdisciplinary Modelling Group InterTech ( who participated in the collection of the experimental data are acknowledged in this work.  ...

Organisational wellness: Human reaction to change

Tonja Blom
2018 South African Journal of Business Management  
Thus, human reactions to change are discussed, as the organisational challenge seems to be how to find workable methods to reduce fear, anxiety and stress.  ...  These concepts depict the negative characteristics of leadership and management which invariably increase individuals' fear, anxiety and stress levels.  ...  The researcher developed Figure 2 , by applying the research findings on human reactions to change and stress and human niches, combined with literature on the brain.  ...

Neurophysiological interpretation of human visual reaction times: effect of contrast, spatial frequency and luminance

S Plainis, I.J Murray
2000 Neuropsychologia  
Reaction Times (RTs) can be used to study supra-threshold contrast coding in humans over the same range of stimulus parameters.  ...  The slope of these functions reveals how contrast is linked to RT and can, therefore, be referred to as the RT-contrast factor with units of msec ×contrast.  ...  Acknowledgements This research is part of a LINK TIO EPSRC-sponsored programme (GR/K56957). We gratefully acknowledge the support of the Department of Transport and Urbis Lighting Ltd.  ...

Serotonin Depletion Induces 'Waiting Impulsivity' on the Human Four-Choice Serial Reaction Time Task: Cross-Species Translational Significance

Yulia Worbe, George Savulich, Valerie Voon, Emilio Fernandez-Egea, Trevor W Robbins
2014 Neuropsychopharmacology  
We used a novel translational analog of a rodent 5-choice serial reaction time task (5-CSRTT)-the human 4-CSRTT-and a reward delay-discounting questionnaire to measure effects on these different forms  ...  Convergent results from animal and human studies suggest that reducing serotonin neurotransmission promotes impulsive behavior.  ...  The Behavioural and Clinical Neuroscience Institute is jointly funded by the MRC and the Wellcome Trust (G00001354).  ...

Obstacles and catalysts of cooperation in humans, bonobos, and chimpanzees: behavioural reaction norms can help explain variation in sex roles, inequality, war and peace

Adrian V. Jaeggi, Michael Gurven, Frances J. White, Klaree J. Boose
2016 Behaviour  
In the logic of behavioural ecology, individuals have been selected to adjust their behaviour along evolved reaction norms that maximize fitness given current socio-ecological conditions.  ...  These socio-ecological conditions therefore constitute key catalysts and obstacles of cooperation. We conclude that human nature should be seen as consisting of evolved reaction norms.  ...  Acknowledgements We thank Peter Verbeek and Douglas Fry for the invitation to the workshop on "catalysts and obstacles of peaceful behaviour" and the opportunity to contribute to this special issue.  ...

Exercise and Time Perception: An Exploration of the Impact of High Intensity Cardio Exercise (Zumba) on Human Timing

2016 Timing & Time Perception  
The current study aims to investigate human interval timing after completion of one of two tasks: listening to an audiobook, or engaging in a Zumba workout.  ...  It was hypothesised that individuals in the Zumba condition would experience a distortion in their timing post workout consistent with an increase in pacemaker speed.  ...  Many stimuli have been linked to distortions in accuracy of timing and some specific features of stimuli have also been shown to impact on human time perception.  ...

Neural activity patterns evoked by a spouse's incongruent emotional reactions when recalling marriage-relevant experiences

Raluca Petrican, Rachel Shayna Rosenbaum, Cheryl Grady
2015 Human Brain Mapping  
The spouse's positive (rather than negative) nonverbal behaviour evoked greater activity in putative mirror neuron areas, such as the bilateral IPL.  ...  Nevertheless, sensitivity to potential incongruities between one's own and an intimate partner's subjective experience is reportedly also important for close relationship quality.  ...  This work was supported by the Canadian Institutes of Health Research (MOP14036), the Canada Research Chairs program, the Ontario Research Fund, the Canadian Foundation for Innovation, and the Heart and  ...
