In this chapter we discuss to which extent the GRID instrument allows to study the meaning of emotion terms from multidisciplinary perspectives and multiple theoretical approaches. First the GRID instrument is evaluated as an assessment tool in terms of reliability and validity. Then the consequences of the findings for the componential, the dimensional, and the basic emotion approaches in psychology are considered. Subsequently we examine how the overall structural similarities across cultural and linguistic groups can function as a tertium comparationis to study differences in specific emotion terms and features. Furthermore we show how the GRID instrument can be used for both semasiological and onomasiological studies in linguistics. We also discuss the further development of the GRID instrument to facilitate the study of specific hypotheses and issues emerging from each of these perspectives and approaches. We end with a discussion of the implications of the results presented in this book for the lexical sedimentation hypothesis.
