Final answer:
The statement is false because self-esteem usually requires time and ongoing effort to change significantly, not just the experience of a one-day seminar.
Step-by-step explanation:
The statement 'A person's self-esteem can be changed in one day through a self-esteem enhancing seminar' is generally considered false. Self-esteem is a complex and deeply-rooted aspect of an individual's self-concept that typically evolves over longer periods of time through consistent and cumulative experiences and efforts. While a seminar may provide tools and insights that can contribute to the process of enhancing self-esteem, it is unlikely to result in immediate and lasting change in just one day. It is more accurate to say that a self-esteem enhancing seminar can start a person on the path to improving their self-esteem, but it would require ongoing effort to see substantial change.
