A throughgoing form of behaviorism that attempts to understand all human behavior, including private events such as thoughts and feelings, in terms of controlling variables in the history of the person (ontogeny) and the species (phylogeny).
(a) Repeating conditions whithing an experiment to determine the reliability of effects and increase internal validity. (See baseline logic, prediction, verification.) (b) Repeating whole experiments to determine the generality of findings of previous experiments to other subjects, settings, and/or behaviors. (See direct replication, external validity, systematic replication.)
A systematic approach to the understanding of natural phenomena (as evidenced by description, prediction, and control) that relies on determinism as its fundamental assumption, empiricism as its primary rule, expermentation as its basic strategy, replication as a requirement for believability, parsimony as a value, and philosopic doubtas its guiding conscience.
