Why is face recognition so interesting? Within the realm of visual cognition, faces have been afforded a degree of analysis that surpasses most other object categories. There are several reasons for this intense scrutiny. First, faces are critical to us as social beings. Thus, we are inherently interested the mental and neural processes responsible for our ability to recognize, interpret, and r...

Multidimensional Scaling

Overview From a non-technical point of view, the purpose of multidimensional scaling (MDS) is to provide a visual representation of the pattern of proximities (i.e., similarities or distances) among a set of objects. For example, given a matrix of perceived similarities between various brands of air fresheners, MDS plots the brands on a map such that those brands that are perceived to be very s...

Multidimensional Scaling

The term ‘Multidimensional Scaling’ or MDS is used in two essentially different ways in statistics (de Leeuw & Heiser 1980a). MDS in the wide sense refers to any technique that produces a multidimensional geometric representation of data, where quantitative or qualitative relationships in the data are made to correspond with geometric relationships in the representation. MDS in the narrow sense...
