2 Non-experimental Designs Flashcards
Used when:
✓ experiment is not practical or desirable
✓ testing a hypothesis in an existing real-life situation is necessary or important
✓ you want to explore unique or rare occurrences, or to sample personal information in natural settings
o All these can provide useful data, either from single individuals or from large groups of people.
NON-EXPERIMENTAL APPROACHES
o A description of an individual’s immediate experience.
o Source of data: personal experience
PHENOMENOLOGY
✓ Was interested in the physiology of vision, and noticed that colours seemed to change as twilight deepened.
✓ Purkinje Effect → understanding of spectral sensitivity to colours of different wavelengths.
Johannes Purkinje (1787-1869)
✓ Dealt with basic psychological issues like habits, emotions, consciousness, and stream of thoughts from the phenomenological perspective of his own experiences.
✓ Resistance of getting up inhibits our movement.
✓ “…we more often than not get up without any struggle or decision at all. We suddenly find that we have got up
William James
cases of deviant and normal individuals are
compared for significant differences.
✓ Differences may have important implications for the etiology, or origin, of the psychopathology in question.
Deviant Case Analysis
o Non-experimental approaches used
in the field or in real-life settings.
o Use of combined types of data
gathering to capitalize on the
richness and range of behaviour
found outside the laboratory.
o There is NO MANIPULATION of
antecedent conditions, but the
DEGREE OF CONTRAINT ON
RESPONSES VARIES considerably
form study to study
FIELD STUDIES
o A descriptive research method in which already EXISTING
RECORDS are being REEXAMINED for a new purpose.
✓ Crime and death rates
✓ Educational levels
✓ Salaries
✓ Housing patterns
✓ Disease rates
o These information can be used to ANALYZE SOCIETAL TRENDS or
to gather information about population subgroups.
ARCHIVAL STUDIES
✓ Studied some controversial issues about African American men — namely, documented discouragement over barriers to employment and problems with family roles — from a positive perspective.
✓ Findings: kinship bonds and religious beliefs were stronger in men who were happy in their family roles.
Bowman (1992)
o Relies on WORDS rather than numbers, for the data being collected.
o Focuses on:
✓ Self-reports
✓ Personal narratives
✓ Expression of ideas, memories, feelings and thoughts
o Appears to be ON THE RISE within psychology.
o Some argue that qualitative research, or the “big-Q”, is a candidate for a PARADIGM SHIFT within psychology.
o Paradigm: the set of attitudes, values, beliefs, methods and procedures that are generally accepted within a particular discipline
QUALITATIVE RESEARCH
✓ Influence of researcher’s own viewpoint in the interpretation of data.
✓ Influence of presence of researcher in the way participants would respond.
✓ Accuracy of self-reports and use of retrospective data.
VALIDITY
a very important measure of its goodness
REPLICABILITY
