     In 1890 William James, the American philosopher and physician and one of the founders of modern

psychology, defined psychology as"the science of mental life" and this definition provides a good starting

point for our understanding even today. We all have a mental life and therefore have some idea about what

this means, even though it can be studied in rats or monkeys as well as in people and the concept remains

difficult to understand.

     Like most psychologists, William James was particularly interested in human psychology, which he

thought consisted of certain basic elements: thoughts and feelings, a physical world which exists in time

and space, and a way of knowing about these things. For each of us, this knowledge is primarily personal

and private" It comes from our own thoughts, feelings and experience of the world, and may or may not

be influenced by scientific facts about things. For this reason, it is easy for us to make judgments about

psychological matters using our own experience as a standard. We behave as amateur psychologists when

we offer opinions on complex psychological phenomena. However, problems arise when two people

understand these things differently. Formal psychology attempts to provide methods for deciding which

explanations are most likely to be correct, or for determining the circumstances under which each applies.

The work of psychologists helps us distinguish between inside information, which is subjective, and may

be prejudiced and unreliable, and the facts: between our predictions and what is"true" in scientific terms.

     Psychology, as defined by William James, is about the mind or brain, but although psychologists do study

the brain, we do not understand nearly enough about its workings to be able to comprehend the part that it

plays in the experience and expression of our hopes, fears, and wishes, or in our behaviour during experiences

as varied as giving birth or watching a football match. Indeed, it is rarely possible to study the brain directly.

So, psychologists have discovered more by studying our behaviour, and by using their observations to obtain

hypotheses (假设) about what is going on inside us.

3. According to the passage, psychologists study the brain mainly _____.

A. in a direct way

B. with their own experience

A. Psychology is also about the ways people use their mental abilities to operate in the world around them.

B. William James is considered to be the greatest psychologist in the 1890s.

D. It is important for psychologists, as well as ordinary people, to be aware of the reasons.
