Assumption
This philosophy guides our practices – without a belief in this philosophy, there would not be a point to our practices
Determinism
Human behaviour obeys the laws of nature
Behaviour acts as other natural events do
All events are related to other events in the past
Subject to scientific exploration and investigation
Determinism
There is order in the universe
Order allows scientific exploration
Scientific inquiry comes from…
The opposite of accidentalism
Determinism
One event is caused by another
Links in a chain
Determinism
Things do not happen by chance
example: an explosion is caused by gas expanding and chemical mixing
Determinism
A prime directive
Empiricism
Observation, measurement, gathering objective facts
Empiricism
Relying on observable facts and not opinions
Direct observation and measurement
Empiricism
To understand something we must describe, predict, and control it
Empiricism
Free from bias
In the sense of saying something is or isn’t true based upon personal prejudice or opinion
Multiple people can observe the same event
Empiricism
Requires clear description of the phenomena so that observation can occur unbiased
Empiricism
Yields qualification of the results
Crosses over all 3 levels of scientific understanding: Description, Prediction, Control
Empiricism
A basic strategy
Experimentation
Conduct experiments, systematically measuring aspects of the phenomena of interest
Experimentation
Used to determine functional relations
Required in scientific inquiry
Systematic and controlled
Experimentation
Manipulate one (environmental) variable and keep other variables constant
Experimentation
What is manipulated in a scientific experiment; variables that are typically thought to have some effect on the dependent variable
Independent Variable
The measured variable; the variable that is affected/dependent upon the IV; not manipulated but observed
In behaviour analysis, this is usually the “behaviour”
Dependent Variable
A necessary requirement for believability
Replication
Not the infallibility or inherent honesty of scientists – is the primary reason science is a self-correcting enterprise that eventually gets it right
Replication
Repeating an experiment as many times as necessary to show same/similar results
Successful results of one experiment = great!
However, value is placed on repeated application yielding same results
Replication
Within one experiment (e.g. a design repeating each condition/intervention twice)
Across many experiments (e.g. across different participants, behaviours etc.)
Replication
Manipulation of variables
Experimentation
Change in one variable to see how it effects the other variable
Experimentation
