12|AULA cd Interior lighting and emotions My motivation behind this work is to comprehend the emotional reactions that a person has when occupying a space, depending on the interior lighting of said space. Also, to observe how the different ways of lighting a space can have an effect, with attention to aspects like the formal relation of the luminaries and the space, or the chromatic relation of materials and light. To study and understand why people react to certain shapes, and to verify if there are common patterns of emotional responses. The starting point hypothesis is: Does interior lighting have an influence in the behavior and in the emotional state of a person? T o discover the emotions felt by a person when present in an interior space, illuminated in a certain way, I selected fifteen images of different interiors and elaborated a questionnaire related to the images. The questionnaire distinguished the sex, age, and education of the person answering. For every image, six specific questions were asked: Three questions were measured in a range of 1 to 5. There was one question that specified the emotions by the selection of 4 types of pleasant emotions and 4 unpleasant. And finally an open ended question to elaborate on any other emotion not covered in the questionnaire. The questionnaire handed out and evaluated was the following: In total, 21 people answered the questionnaire, among them 11 females and 10 males.

CONTENT OF THE RESEARCH WORK First, I will show the images and the graphics, with the answers to the survey. Secondly, I will explain, with scientific concepts, my assessments for every image, completed prior to the survey. Finally, I expound a general conclusion for every image, comparing the results obtained in the questionnaire with my preliminary results. Preliminary conclusions (image 1) The emotion I get from Image number 1 is inspiration, because of the predominant green color and the feeling of relaxation created by the coherence between the luminaries and the space. Final conclusions After administering the questionnaire, I came to the conclusion that my preliminary opinions were consistent with the final results of the people surveyed. We coincided in topics such as the relation between the luminaries and the space, which obtained an adequate value; color temperature, emphasis on cool tones; the relation between color of light and materials, an adequate relation, etc. Both males and females, emphasized a pleasant sensation, with a predominance of the emotion of inspiration for women and a tie between inspiration and fascination for men. Other emotions that were associated with this image, in the questionnaire, were: tranquility, relax, etc. Preliminary conclusions (image 2) The emotion that image number 2 evoked in me was intimate, due to the predominance of the color red in combination with the warm light, the rough texture of the materials and the space where they are located. Final conclusions After administering the questionnaire I had the same results of the previous photograph. My preliminary conclusions coincide very closely with the final results
