My current research focuses on the way spatial context influences people´s evaluation of objects. I study how people evaluate objects located in an “affective force field” where objects influence other objects as a function of distance. For instance, I blend evaluative judgment theories from social cognition (assimilation and contrast) and psychophysics (range effects) with artificial neural network techniques to understand how locations that elicit strong affective reactions, i.e., « hotspots » like an unsafe housing block or a nice public park – influence people´s evaluation of the surroundings. The resulting model can predict people’s preferred location in a geographical area containing multiple hotspots with an encouraging accuracy. I will present some of my previous empirical findings with the experimental method and the validation of the more recent model based on artificial neural networks.
