- [FROM Dennis Delprato (920813)]
-
- I have been enjoying the discussion of disturbances and simplifying
- assumptions. For those who wish to talk to non PCT experimental
- psychologists, I suggest you have an excellent "hook" here.
-
- Start at the beginning. What is the raison d'etre of the much
- acclaimed experimental method? Control over so-called extraneous
- variables that are the source of unaccounted-for (error) variance
- in events of interest. How successful is the IV-DV strategy?
- Citation, citation, .... Not very, even when statistical control in
- the form of factorial designs and multivariate statistics is
- incorporated into the manipulative strategy. Furthermore, aren't
- we aware of a fundamental problem with highly controlled
- experimental research, even when (or if) its application permits
- impressively confirmed predictions? Yes, we find the actual
- world controlled away such that results are applicable to only
- a very restricted set of conditions. We end up not knowing any more
- than before the rigorous experimentation was conduct--with the
- exception of what applies to an extremely narrow range of conditions.
- Tied in here are ceteris paribus assumptions in an attempt to salvage
- the experimenter-as-manipulator methodology.
-
- Thirdly, what is one implicitly assuming when control over
- extraneous variables is placed in the hands of the experimenter?
- Aren't we assuming that the individual is pushed and pulled around
- by external forces, that they are not active participants in their
- world?
-
- Well, here's a suggestion from an area that is based on the
- fundamental proposition that the psychologically-active
- individual always participates fully in all actions. First,
- consider this notion of extraneous variables; this idea that
- there are variables that often operate insidiously to befuddle
- well-intentioned researchers. An alternative is not to deny
- that something like extraneous variables is found in psychological
- events, but to re-conceptualize them as disturbances. With
- the idea of disturbances and the conceptual framework in which
- they are found as formal constructs, we (a) need not rely on
- a wind-weather vane conceptualization of psychological behavior,
- (b) can methodologically handle all variables of whatever number
- and however classified by the classical experimental model....
-
- Get the point? KISS (Keep It Simple ...)
-
- Basically, I am suggesting a critical look at the classic
- experimental framework (CEF), a set of assumptions not questioned by
- adherents to otherwise divergent theories and approaches. CEF-thinking
- is taught to all psychologists. It is possibly one of the very few
- points of general agreement in the fractured field of psychology.
- Not a pleasant thought for those who are not impressed with it.
- However, it does seem that there may be enough of an undercurrent
- of dissatisfaction to lead some, at least, to consider an alternative.
