Introduction & Overview

Research Methods, what's the deal with them?

Why is it that we spend so much time developing, talking about,
 and examining the methods we use to conduct research?

Cozby indicates that there are many uses of research methods:
    1) Making sense of News and Scientific Reports in everyday life
    2) Limitations to other sources of knowledge (i.e. intuition and Authority).
    these include skepticism in empiricism and the principle of falsifiability

Background to Research Methods

Starting with an interest to know something about someone (else) and
trying to make sense of their behaviour or possibly even to predict and control it.

In the simplest sense the ways in which we get to known someone can be considered
 to be the "methods" that we use to "research" or gather facts about other people.

How do you know someone?

Historically this has been going on for a very long time, however
it became systematized in the 19th century, as psychology moved philosophy
to its own separate discipline.

The scope of Human Knowledge  

The sciences each have their own assumptions and methods

It was largely the use of "scientific" methods that made the difference;
that "constructed the subject", the discipline of psychology.

According to Kurt Danziger (1990) early psychologists turned to methodology
 as a way to make their knowledge claims more legitimate, more respectable,
and ultimately more marketable.

He points out that making use of aggregate data (group data) and how individuals
vary (like the bell curve) with respect to group norms (means), these methods became
 a tool for psychologists to gain respect and be considered a "real" science. 

As a result, Danziger identifies this "methodolotry" as coming to dominate
disciplinary discourse in psychology in trying to become a real science.  

What this means is that we have come to idolize, almost pray to the sacred methods.

Along side of this strong emphasis on becoming  "Real Science", 
this has also lead to the ongoing debate over whether or not psychology
 is a  "pure" or "basic" research discipline or merely an "applied" professional practice.

All of this begs the question: what is "Real Science"?


Introduction to Scientific Research Methods in Psychology

Consideration of the history of research methods requires a look at the history of science and the philosophy of science.

What is science?

A basic question asked by many and answered in almost as many ways. Early roots of science (as with much of western thought) begin with Plato and his search for everlasting truth and reality.

The Philosophy of Science

Many diverse view on the nature of science exist today, generally the biggest division lies in the Natural Science - Human Science division. Initially articulated by Wilhelm Dilthey, this distinction plays a major role in the understanding of science and the practical use of scientific methods for psychology. (see world-views for more detail)
 
  What is the Philosophy of Science?

Harre (1986) The aim of the philosophy of science
is to make manifest the principles used in the practice of science.

Two kinds of accounts: Descriptive and Prescriptive
   

Descriptive Accounts: What science is.

Rom Harre (1986): Four traditional branches to Philosophy

i) Epistemology: The theory of knowledge
(sources and methods for validation, including theories of truth)
-Examples: Empiricism and Rationalism;
correspondence and coherence

ii) Logic: The study of correct reasoning
-Examples: Deduction and Induction

iii) Metaphysics: The careful study of concepts or first principles
such as: Substance, Quality, Causal Relations
-Examples: (Ontology) Idealism and Materialism

iv) Ethics: The theory of (moral) evaluation.
Not traditionally a part of science, although many
current philosophers of science suggest that it cannot be avoided

Thomas Kuhn (1970): Paradigmatic Revolutions

Science is based on Paradigms or "worldviews" (Weltanschauungen) which are perspectives shared by the members of scientific communities

Historical development of Sciences:
Pre-paradigm, Normal Science, Crisis, Revolution . . .

Paradigm: an accepted model or pattern, perspective.
It serves to organise our perceptions or ways of thinking about the world

Disciplinary Matrix: The set of fundamental (unstated)
assumptions underlying the paradigm. Usually unconscious,
and not subject to empirical testing

Shared Exemplars: Models of good research through which
students "learn to see" the world through the paradigm's
perspective

Implicit Hermeneutics: interpretation, dialectic between "observer"
and "the world", value sensitive and critical of paradigm choice.

Methods in Science are built into a paradigm. Just as reality & knowledge are understood from within the paradigm, so too are methods specific to the model of science that is defined.

 

Prescriptive Accounts: What science should be.

Logical Positivism (Logical Empiricism)

Vienna Circle (1930) Drawing from Auguste Comte and Ernst Mach
Emphasis on logic and objective observation.
Description, prediction and control are goals of science.

Verification of generalizations (Laws) is central to methods

Much of the methods of psychology are built upon this model of science. Thus the bulk of what we know through our text and others like it are part of this positivist view of science that comes out of behaviourism and the rise of operationism in psychology.
 
  Cozby indicates that science involves: Description, Prediction and explanation (at least good enough)
    Predictions involves attempts to establish causation through:
        1) Temporal precedence, 2) covariation, 3) no alternative explanations

Sir Karl Popper (1902-1994): Falsificationism

(1933) Demarcation Criteria: Science is divided from pseudo-science or "myth" by making statements which are potentially falsifiable

Bold conjectures and refutations ought to be the methods of science

Two contexts of activity: Discovery and justification. It does not matter where your theories and hypotheses come from, it is the method of falsification that makes it scientific.

Margaret Benston (1989):
Feminist Critique of Scientific Values!

Critical of the sex roles and stereotypes of scientists, presumptions of objectivity in methods, and power imbalances associated with typically masculine science's "impoverishment of reality" to "anti-human ends"
