Chapter 2 Flashcards
As most researchers in the multicultural arena would agree whereas our methods may aim for objectivity, our results and interpretations are
laden with subjective values
Internal validity refers to
causal inference. It suggests that our changes make a difference
The reason researchers randomly assign potential research participants to experimental and control groups is to have
more confidence that the changes in procedures cause differences in the behavior
external validity refers to
generalizability of the result we obtain. External validity may be - and often is - at odds with internal validity. Increasing one may jeopardize the other
Even though psychologists have recognized that both internal and external validity are important, the notions that internal validity is indispensable in experimental design and that external validity is never completely answerable have influenced the field to markedly
favor internal validity over external validity. Sue called this selective enforcement of scientific principles
quantitative study
research that involves turning questions into meaningful numbers that can be compared with other numbers. Our entire system of statistics is based on comparing numbers to make inferences about differences between groups and individuals
logical positivism
a scientific approach that attempts to measure truth or real phenomena through methods of numbers and statistical analyses
collecting only numerical data may result in the loss of some important information and/or may ignore contextual variables that could affect how we respond
Qualitative approach to research can be employed when a researcher determines that gathering strictly numerical answers to questions results in the loss of essential information
Intersubjective approach
treats individuals within societies as quasirational arbiters, so there collective wisdom is most likely close to the norm of society. This approach has 3 premises:
a) people often act based on their perception of the beliefs and values of the wider society; b) the immediate environment plays a role in one’s perception of the broader society’s beliefs and values, so not everyone in a society has the same intersubjective perception; and c) intersubjective perceptions are sometimes distinct from one’s personal beliefs and values
Two reasons why qualitative methods have not been widely employed:
- They typically use far fewer research participants and require more time to gather information because of the interview format of data collection.
- there is no agreement on the best ways to interpret the information we receive
functional equivalence
the equating of items on a test or a survey functionally. For example, if we were to inquire about a child’s knowledge of and conclusions about fairy tales, we might select Beauty and the Beast if we were testing children in this country, whereas we were testing children from a different background we might select a well-known fairy tale from the child’s country of origin
conceptual equivalence
refers to the term or phrase that is culturally meaningful equivalent of the term being examined. For example, the term depression does not exist in some cultures, but if one were to describe a condition wherein an individual experiences fatigue and slowness of thought, the symptoms could be identified by those cultures. Thus, although the term depression does not exist in those cultures, the condition of depression does
linguistic equavilence
the translation of a term that carries with it similar meaning from one language to another. Most people have accepted the standard that measures must be back-translated instead of merely translated
Back translation
is a procedure whereby the measure is translated into the target language and then translated back to the original language. If the back translation is the same or nearly the same as the original, then the translation is acceptable for the study. However, sometimes a back translation is very different from the original phrasing, so a different translation must be sought.
metric equivalence
numeric scores that are generally equivalent from one culture to another. Some cultures may be risk-averse and not select the extremes of the possible answers. For example, in a culture that tends to be risk-averse, research participants presented with a 7-point scale may select 6 as the highest score, so the researcher may have to make 6 in that culture the equivalent of 7 in a culture that uses the full range of the scale
