Why Science Matters 
Understanding the Methods of Psychological Research

Why Science Matters: Understanding the Methods of Psychological
Research rises above standard research methods texts by
presenting an up-to-date view of contemporary psychological science
as it is currently understood and practiced.

* * Explores not only the procedural aspects of psychological
research, but also delves into the issue of how to accomplish
effective science.

* * Explicates how hypotheses and theories are to be
evaluated.

* * Suggests that the proper approach to devising and evaluating
theories is by abduction, not by induction or deduction alone.

* * Incorporates new investigatory procedures, current
methodologists, conflicts and issues, implications of the
philosophy of science, and a lively prose style.

* * Provides a picture of science that will engage students and
expand their abilities as both scientists and psychologists.
