The field of psychology that concerns itself with issues of human dignity, free will, and self-reflection is humanistic psychology.

The field of psychology that concerns itself with issues of human dignity, free will, and self-reflection is option 3) humanistic psychology. To arrive at this answer, you can use a combination of knowledge about the different branches of psychology and process of elimination:

1) Cognitive psychology focuses on mental processes such as thinking, memory, perception, and problem-solving. It does not primarily deal with issues of human dignity, free will, and self-reflection, so it can be eliminated as an option.

2) Behaviorist psychology focuses on observable behaviors and the environmental factors that influence them. While it recognizes the importance of understanding human behavior, it does not specifically address human dignity, free will, and self-reflection. Hence, it can also be eliminated.

3) Humanistic psychology places emphasis on human dignity, personal growth, and self-reflection. It considers individuals as having free will and the ability to make choices that shape their lives. These aspects align with the description provided in the question, making it the most suitable option.

4) Psychobiology, also known as biopsychology or neuroscience, focuses on the biological basis of behavior and mental processes. It predominantly explores the relationship between the brain and behavior rather than human dignity, free will, and self-reflection. Therefore, it can be eliminated as well.

In conclusion, after considering the characteristics of each branch of psychology, option 3) humanistic psychology is the field that concerns itself with issues of human dignity, free will, and self-reflection.
