What is the most common first reaction to change, according to the change curve model?

Acceptance occurs later in the change curve after individuals have processed their feelings and acknowledged the change. It represents a positive adaptation to the new situation, but it is not the immediate reaction that people typically experience when faced with change.

Relief may occur after individuals have come to terms with change and recognize that it may lead to positive outcomes. However, it is not a common initial reaction; instead, it often follows a period of adjustment and acceptance of the new reality.

Concern can manifest as individuals begin to understand the implications of change, but it does not typically precede denial. While individuals might feel concerned about a change, it is usually the denial of the situation that initially dominates their emotional response before they can address their concerns.
