Expressive vs Instrumental: What are the differences?

# Introduction
When it comes to understanding human behavior, two key concepts that are often discussed are expressive and instrumental behaviors. While they may seem similar at first glance, there are distinct differences that set them apart.

1. **Motivation**: Expressive behaviors are driven by a desire to communicate emotions, thoughts, or feelings, whereas instrumental behaviors are driven by a goal-oriented outcome or specific purpose. In expressive behavior, the focus is on the expression itself, while instrumental behavior is focused on achieving a desired result.

2. **Communication**: Expressive behaviors serve as a form of self-expression and communication of internal states, whereas instrumental behaviors are more about achieving a task or goal. Expressive behaviors may not always have a clear objective other than to express emotions, while instrumental behaviors are more task-oriented and aim to fulfill a specific purpose.

3. **Emotional Expression**: Expressive behaviors are closely linked to emotional expression and are often used to convey feelings or thoughts, while instrumental behaviors may not necessarily involve the expression of emotions and are more about completing a task efficiently.

4. **Timing**: Expressive behaviors are often spontaneous and can occur in various situations without a specific trigger, while instrumental behaviors are more likely to be planned or executed in response to a specific need or goal.

5. **Focus**: Expressive behaviors are centered around the self and the need to express internal states, while instrumental behaviors are focused on external factors and achieving external goals or outcomes.

6. **Impact**: Expressive behaviors may have a more subjective impact on individuals, as they are often perceived differently by observers based on their interpretation of the expression, whereas instrumental behaviors have a more objective impact that can be measured based on the achievement of the desired outcome.

In Summary, expressive behaviors are driven by the need for emotional expression and communication, while instrumental behaviors are goal-oriented and focused on achieving specific outcomes.
