LEARNING OBJECTIVES
• By the end of this session, you should be
able to:
– Analyze the main components of qualitative
and quantitative research
– Discuss the philosophical assumptions (and
logic) of various scientific paradigms
– Analyze how philosophical paradigms
influence research method and substance
– Articulate a personal stance
POST-MODERNISM
• Definition
– Intellectual movement that challenges modernist
conceptions (“grand narratives”) of science, truth, and
objectivity (Gergen, 2000; Patton, 2002)
– Language can not fully capture truth or reality (Crisis
of Representation)
– Argues that truth is constructed through language,
and language constructed through cultural processes
(language games, consensus, power)
– Science is social constructed
– Values multiple truths
POST-MODERNISM
• Methodological/Theoretical Significance
– Influential in social sciences and humanities
(Psychology slower to adopt than other disciplines)
(Gergen, 2000)
– Research focuses on social construction of reality
through language, symbols, metaphors, etc.
– Phenomena treated as text
– Analysis through deconstruction (take apart text to
expose hidden assumptions, contradictions,
ideological interests) (Patton, 2002)
POST-MODERNISM
• Methodological/Theoretical Significance
– Conclusions are localized, tentative, tolerate
dissensus (Johnson & Cassell, 2001)
– Reflexivity (esp. Epistemological)
– Influenced discourse analysis and narrative
methodological orientations
– Risk of extreme moral or epistemological
relativism, which can justify oppression or
undermine value of all knowledge
POST-MODERNISM
• Example
– Examines implications of post-modernism for the discipline of
work psychology
– Work psychology dominated by positivism, excludes subjectivity
(Qualitative approaches still based on positivist understanding)
– Limits what is known about work, limits reflexivity in psychology
research and practice
– Postmodernists erode apparently self-evident meta-narratives
through:
• Identifying particular ways of seeing and acting that a discourse
takes and excludes;
• Analysing social processes that make it possible for such a
discourse to be historically constituted
• Analysing how it is reconstituted into new discursive formations
• Identifying the effects of such a discourse upon people.
POST-MODERNISM
• Example
– Discipline and sub-disciplines of work psychology
seen as discourses that are constructed to define
legitimate work psychology that exclude non-qualified
members and restrict acceptable forms of knowledge
– Phenomena such as stress, personality, motivation
not seen as real objects, but as linguistic constructs
taken to be real and produced by discipline
• Examine how constructs stress come about (stressologists
industry)
– Human Resource discourse found to reflect
masculine regimes of rationality that exclude and
suppress women as irrational (management selection
tests based on masculine norms)

PHILOSOPHY OF SCIENCE
• What is philosophy of science?
– Conceptual roots undergirding the quest for
knowledge
– Fundamental beliefs or assumptions about
•
•
•
•
•
Ontology (the nature of reality and being)
Epistemology (the study of knowledge)
Axiology (the role of values in the research process)
Methodology (the process and procedures of research)
Rhetorical structure (the language of the research) and
presentation of the research)
PHILOSOPHY OF SCIENCE
• Why think about philosophy of science?
– Increases clarity of research purpose
– Enhances reflexivity
– Broadens and deepens theoretical sensitivity
– Increases quality and rigor
PHILOSOPHY OF SCIENCE
• Science
– Definition
• Systematic collection and analysis of data
• Create knowledge and solve problems
– Empiricism
PHILOSOPHY OF SCIENCE
• Paradigms
– Set of interrelated assumptions about the world which
provides a philosophical and conceptual framework
for the organized study of that world (Filstead, 1979 in
Patton, 2002)
• Ontology, Epistemology, Methodology, Axiology, Rhetorical
Structure
– Major Paradigms
• Reality-oriented
• Social Constructionist
• Critical-Ideological
PHILOSOPHY OF SCIENCE
• Reality-oriented Paradigms
– Belief in external reality, where events result from underlying
mechanisms or structures
– Objectivity is desirable
– Goals are explanation, laws, prediction, control
– Variations
• Positivism (Comte)
– Real knowledge based on claims that are verifiable by direct experience
(mathematical formulas); distinguish “positive knowledge” (empirically based) from
theology and metaphysics (based on fallible human reason and belief)
• Post-positivist (Popper)
– Human ability to gain real knowledge is limited. Falsification over verification as
criteria for assessing claims
• Realism
– Similar to post-positivism. Recognize subjectivity and takes pragmatic rather
formalistic approach to research. No difference between qualitative and
quantitative methods.
PHILOSOPHY OF SCIENCE
• Social Constructionist Paradigms
– Believe in multiple, equally valid realities
(subjective and socially constructed)
– Goals are understanding lived experience
(verstehen)
– Heisenberg Uncertainty Principle
PHILOSOPHY OF SCIENCE
• Critical Paradigms
- Believe that reality mediated by power
relations within social, historical contexts
– Goals are emancipation and transformation

universal laws, can be known with some certainty

know)
• Relationship between Knower and Known
