Step 1: Identifying the Author of a Key Psychological Work:
The question asks to identify the author of the 1971 book "Beyond Freedom and Dignity".
Step 2: Detailed Explanation of Authors:
B.F. Skinner: Burrhus Frederic Skinner was a highly influential American psychologist, behaviorist, author, inventor, and social philosopher. He was a proponent of behaviorism, which holds that behavior is determined by its consequences (reinforcements or punishments). His 1971 book, "Beyond Freedom and Dignity", argues that concepts like "freedom" and "dignity" are outdated and that human behavior can be engineered for the better through a scientific approach. This is the correct answer. (Note the typo "Skinnes" in the question).
Georg F.W. Hegel: A German philosopher and a major figure in German idealism. His work is in philosophy, not behaviorist psychology.
J. Krishnamurti: An Indian philosopher, speaker, and writer. His concerns were primarily spiritual and philosophical.
Amartya Sen: A Nobel laureate in economics and a philosopher, known for his work on welfare economics and the capability approach.
Step 3: Final Answer:
The author of "Beyond Freedom and Dignity" is B.F. Skinner.
