This chapter will focus on the antecedents, or precursors, to motivating language that work to establish a leader’s credibility, believability, and understandability. The greater a leader’s credibility, believability, and understandability, the stronger the foundation for motivating language to occur and influence employees and organizations. The weaker a leader’s credibility, believability, and understandability, the weaker the foundation for motivating language to occur, and the less likely the leader will influence employees and organizations. This chapter will examine antecedents such as behavioral integrity, source credibility, and dynamism that form a leader’s image, as well as the pre-antecedents that comprise a leader’s vocal image, such as the willingness to communicate, oral delivery, filler words, and vocabulary. Finally, this chapter will conclude with a discussion of implications and provide guidance on future research areas.
