Indeed, several lines of investigation using fMRI have described a specialized area of the brain mediating maternal love ( Noriuchi et al., 2008 Noriuchi and Kikuchi, 2013) and, fMRI studies have implicated multiple brain systems particularly the reward system in romantic love ( Aron et al., 2005 Fisher et al., 2005, 2010 Beauregard et al., 2009). Research has compared the brain activity of people who were deeply in love while viewing a picture of their partner and friends of the same age using functional magnetic resonance imaging (fMRI) and concluded that there is a specialized network of the brain involved in love ( Bartels and Zeki, 2000). In recent years, the neuropsychological approach to study the nature of love has gained prominence. Other studies have found a poor correlation between these and other love scales with different types of love ( Whitley, 1993 Sternberg, 1997 Masuda, 2003 Graham and Christiansen, 2009).

However, data analysis from the administration of the LAS, Sternberg’s scale and the Passionate Love Scale by Hatfield and Sprecher’s (1986) found a poor association with all forms of love ( Hendrick and Hendrick, 1989).

Robert Sternberg Triangular Theory of Love and Clyde and Susan Hendrick’s Love Attitudes Scale (LAS) are notable attempts to employ the psychometric approach ( Hendrick and Hendrick, 1986 Sternberg, 1986). Some social psychologists have tried to define love using psychometric techniques. However, the application of this approach has been unsuccessful in all forms of love ( Berscheid, 2010). Indeed, it has been described as a propensity to think, feel, and behave positively toward another ( Hendrick and Hendrick, 1986). Scholars across an array of disciplines have tried to define the meaning and nature of love with some success but questions remain.
