Answer:
d. an approach to gaining knowledge about behavior and mental processes by observation and measurement only
Explanation:
In philosophy, empiricism is a school of psychology that focuses in the way we gain knowledge and it establishes that <u>we can only gain real knowledge by the information we get from our senses and experiences</u>, in other words, empiricism gives importance to the <u>empirical evidence</u> that we gain from our experiences and therefore to the observations and measures we can do (instead of relying on reasoning and what our mind tells us)
Therefore, empiricism is an approach to gaining knowledge about behavior and mental processes by observation and measurement only.
