Simple and complex images: Operationalization and first calibration

The aim of this study is to operationalize the construction of the complexity related to images. In particular, we want to calibrate the judgments of complexity related to colourful images and black and white images who belong to different categories (animals, fruit, transports, technological tools and faces) and examine the parameters related to the different levels of their categorical complexity. The first part of this composition put forward a definition of the construction, a comparison between the various theories of the complexity of the images and an analysis of the various fields of application. In the second part, the purpose is to operationalize the construction, together with the method, the procedures used, and the sample that are described in detail. The article ends with a debate about the results and some thoughts about the importance to operationalize the construct of the complexity. The added value of this study is to provide, for the first time, a contribution to the operationalization of the construct of complexity. The complex and simple images can be used by the scientific community as a catalog that could be used in different fields of application (for example clinical/experimental, marketing/advertising, etc.).
