Final answer:
A questioning attitude towards psychologists' assumptions aligns best with critical thinking, which is a key skill developed in psychology education.
Step-by-step explanation:
A questioning attitude regarding psychologists' assumptions and hidden values best illustrates critical thinking. This skill involves the informed skepticism and the ability to recognize the presence of bias or underlying assumptions in psychological theories or in the interpretation of data. A strong undergraduate education in psychology often includes exposure to critical thinking, the use of the scientific method, and the critical evaluation of sources of information, as these are crucial for engaging in rigorous scientific inquiry. It is essential in psychology to avoid common cognitive biases such as the confirmation bias, the tendency to seek information that supports pre-existing beliefs while ignoring contradictory evidence, and illusory correlations, mistakenly perceiving a relationship between two variables when none exists. Understanding and practicing critical thinking can help prevent these errors in judgment.
