What is defined as an individual's characteristic style of behaving, thinking, and feeling?

The term that best describes an individual's characteristic style of behaving, thinking, and feeling is personality. Personality encompasses the unique patterns of thoughts, emotions, and behaviors that define a person and influence how they interact with the world around them. It is a complex interplay of innate traits and learned behaviors that develop over time.

Temperament refers more specifically to the biological and inherent aspects of an individual’s personality, often observable from a very young age, which contributes to how they respond to their environment emotionally and behaviorally. While temperament is an important component of personality, it does not capture the full range of individual behaviors and thought processes that personality does.

Synchronization generally refers to the coordination of processes or actions, and it is not related to the individual behavioral styles, thoughts, or feelings.

Attachment describes the emotional bond that develops between individuals, particularly seen in relationships like that between a child and caregiver. It focuses more on the quality of relationships and emotional security rather than a comprehensive view of an individual's behavior, thoughts, and feelings.

Thus, personality is the most encompassing term for the characteristic style of behaving, thinking, and feeling.
