11. history - CORRECT ANSWERS.✔️✔️refers to events that occur during an experiment, but are not
related to planned procedural changes that may influence the outcome
12. maturation - CORRECT ANSWERS.✔️✔c️ hanges in behavior due to passage of time
13. testing - CORRECT ANSWERS.✔️✔️threat in any study that requires participants to respond to
the same test repeatedly

baseline or probe testing or observation sessions
15. inhibitive effect - CORRECT ANSWERS.✔️✔️a deterioration in performance over successive
baseline or probe testing or observation sessions

behavior is influenced by more than one planned "treatments" or interventions during the
course of a study
17. sequential confounding - CORRECT ANSWERS.✔️✔w ️ hen the order in which experimental
conditions are introduced to participants influences their behavior
18. carryover effect - CORRECT ANSWERS.✔️✔️the effect when a procedure used in one
experimental condition influences behavior in an adjacent condition
