Alternatives to Experimentation: Non-Experimental Designs Flashcards
Non-experimental approaches may have greater _: the generalizability or applicability to people and situations outside the research setting.
external validity
_ are used when an experiment is not practical or desirable, teasing 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.
Non-experimental Approaches
There are two major dimensions in research:
- Degree of manipulation of antecedent conditions
- Degree of imposition of units
_ is a description of an individual’s immediate experience where our source of data are personal experiences.
Phenomenology
Phenomenology has _ degrees, where antecedents are _ and _ are imposed.
Low-low degrees; not manipulated and data may consist of any immediate experiences, no constraints
_ was interested in the physiology of vision, and noticed that colors seemed to change as twilight deepened.
Johannes Purkinje
_ is the understanding of spectral sensitivity to colors of different wavelengths.
Purkinje Effect
_ dealt with basic psychological issues like habits, emotions, consciousness, and stream of thoughts from the phenomenological perspective of his own experiences.
William James
In _, researchers cannot be sure if the process in observing experiences is not altered by attention to it. Researchers may not be able to achieve the degree of accuracy and objectivity if they observe their own behaviors. It will be difficult for others to replicate our experiences and apply scientific criteria to the findings.
Phenomenology
_ cannot be used to understand the causes of behavior. It describes, but it does not explain a behavior. It may lead researchers into areas of discovery that might otherwise go unnoticed.
Phenomenology
_ may lead to the formulation of new hypothesis and have elements that are mostly combined with other research methods. It is a frequent component of qualitative research.
Phenomenology
Case Studies _ and _ degrees, where it involves _ of antecedent conditions and a _ descriptive record of a single individual’s experiences or behaviors, or both, kept by an _ observer.
low-low and low-high;
no manipulation;

Some case studies will _ the kind of info collected, placing it on the low-high category.
severely restrict
According to Kazdin (2003), there are 5 major purposes of case study:
- They are a source of inferences, hypotheses and theories.
- They are a source for developing therapy techniques.
- They allow a study of rare phenomena.
- They provide exceptions, or counter instances to accept ideas, theories or
practices. - They have persuasive and motivational value
In case studies, _ are where cases of deviant and normal individuals are compared for significant differences.
Deviant Case Analysis
Case studies pose the following limitations:
- One or few subjects may not be a representative of the general population.
- We may not be aware of all the relevant aspects of a person’s life if we are not able to directly observe him/her all the time.
- Subjects or other sources of information may neglect to mention important information because it is irrelevant or embarrassing.
- It relies on retrospective data - data collected in the present based on recollections of past events.
- Researchers cannot make cause-and-effect statements about behaviors observed.
In case studies, record made at the _ are always preferred.
time of an event
_ are non-experimental approaches that are used in the field or in real-life settings.
Field Studies
In _, the use of combined types of data gathering to capitalize on the richness and range of behavior found outside the laboratory.
