What is defined as one’s tendency to react to stimuli in a consistent emotional manner?

The definition provided refers specifically to affectivity, which encompasses an individual's consistent emotional responses to various stimuli. Affectivity is a broad term that captures the range of feelings and emotions an individual can experience, including both positive and negative emotions. This term is often used in psychology to examine how these emotions can influence behavior, motivation, and interactions with others.

Positive affectivity and negative affectivity, while components of affectivity, refer to specific dimensions of emotional response. Positive affectivity relates to the tendency to experience positive emotions and engage with the environment in an optimistic way, whereas negative affectivity is associated with a propensity to experience negative emotions and react to situations with negativity or distress.

The term motivator does not fit within the context of emotional tendencies, as it is more related to the driving factors behind an individual's behaviors and goals rather than their emotional responses to stimuli. Thus, affectivity captures the broader concept of consistent emotional responses, making it the most accurate choice.
