Axes de recherche
COLOUR EXPERIENCE has been born out of common interests of La MAESTRIA and the Colour Psychology team headed by Prof. Christine Mohr at the University of Lausanne in Switzerland. After several encounters and exchanges with the public, we realized how important and urgent it is to share empirically-based knowledge on the subjective experience of colour. The current collaboration unifies competences from academic, scientific, artistic and communication fields to valorize the scientific approach to understand how colour affects us.
We aim to contribute our experiences by creating a public platform on which recent findings, projects, and services can be communicated. This platform represents an online interface on which interested people can find information, participate in psychological research on colour, ask questions, look for potential services (seminars for the general public, training of professionals working with colour), or ask for collaborations.
COLOUR EXPERIENCE will exclusively focus on how colours are experienced and how such experiences interact with our behaviour. Our major approach is based on results gathered from scientifically controlled studies. We wish to provide knowledge on evidence-based studies testing the manifold questions and assumptions we can regularly encounter in the scientific and popular literature.

Experiencing the impossible and its effect on beliefs and cognition

Causal links between magical belief and adult cognitive functioningIt is generally assumed that magical beliefs become established in childhood and endure into adulthood. Magical beliefs keep influencing adult behavior , but we know little about whether cognitive tendencies that co-occur with magical beliefs foster or result from these beliefs. The current project will shed some light on this question.

This research project focused on mechanisms underlying hemispheric specialization in human. It was evoked by the fact that the traditional views of hemispheric specialization only holds true for cerebral lesions and for split brain patients, but that it is difficult to reliably show it in individual healthy subjects. We hypothesized that intra- and inter-individual differences in brain lateralization might be sustained by differences in the electric neural state before the incoming of the stimulus. Our 2nd hypothesis was that this momentary functional state of the brain varies over time, and also between men and women. Finally, we hypothesized that it varies over the different phases of the menstrual cycle within women. To test these hypotheses, we performed several behavioral, electrophysiological and clinical studies. Our main aim was to further elucidate and understand hemispheric specialization in the healthy and pathological brain. We developed a bilateral lexical decision task with simultaneously presented words and non-words. Subjects had to indicate by button press on which side a word appeared. Words are presented very briefly and subjects were not aware that some of the words were of emotional connotation. Behavioral results showed a general better detection of emotional words. Most striking was the difference for words presented to the left visual field, i.e. to the non-dominant hemisphere, where neutral words were detected at chance level. The analysis of the electrophysiological data showed that this emotional word advantage depended on the momentary state of the brain just before stimulus presentation. This state dependency was more pronounced in men. Women showed most man-like behavior during the menstrual phase. The analysis of the event-related potential showed early differences between emotional and neutral words. Again, this was more pronounced in men than women. Women show more bilateral activation after word presentation than men in the time period where language processing takes place.

Humans like some colours and dislike others, but which particular colours and why remains to be understood. Empirical studies on colour preferences generally targeted most preferred colours, but rarely least preferred (disliked) colours. In addition, findings are often based on general colour preferences leaving open the question whether results generalise to specific objects. Here, 88 participants selected the colours they preferred most and least for three context conditions (general, interior walls, t-shirt) using a high-precision colour picker. Participants also indicated whether they associated their colour choice to a valenced object or concept. The chosen colours varied widely between individuals and contexts and so did the reasons for their choices. Consistent patterns also emerged, as most preferred colours in general were more chromatic, while for walls they were lighter and for t-shirts they were darker and less chromatic compared to least preferred colours. This meant that general colour preferences could not explain object specific colour preferences. Measures of the selection process further revealed that, compared to most preferred colours, least preferred colours were chosen more quickly and were less often linked to valenced objects or concepts. The high intra- and inter-individual variability in this and previous reports furthers our understanding that colour preferences are determined by subjective experiences and that most and least preferred colours are not processed equally.
Numériser l'art visuel - Est-ce qu'une visualisation enrichie par la perception multimodale augmente notre expérience esthétique ?
2016 - 2016
Organisme subventionnaire: UNIL-EPFL (Suisse)
Requérant·e: Christine Mohr
Les oeuvres d'art telles que des peintures sont visuellement riches et sont le lieu d'une interaction hautement complexe entre la lumière et le medium. La numérisation standard consiste à prendre une photographie de l'oeuvre. Cependant, la richesse perceptive de l'oeuvre est irrémédiablement perdue durant cette opération. Dans le projet actuel, nous proposons d'investiguer comment les personnes utilisent et répondent (partenaire UNIL, SSP-IP) à de nouvelles solutions perceptives (partenaire EPFL, projet eFacsimileI, IC-LCAV) qui permettent la visualisation et la manipulation d'oeuvres d'art visuelles au travers d'une interface interactive multimodale. Deux études prévues auront lieu à la Fondation Martin Bodmer et à l'EPFL.
