Mass trial
A procedure in discrete-trial teaching during which the same learning trial (SD) for an acquisition skill is presented several times in a row.
Massed practice
A self-management procedure that aims to decrease challenging behavior by having an individual engage in the repeated performance of the challenging behavior.

Matching law
A behavioral concept that maintains that behavior is produced in direct proportion to the reinforcement that is available for that behavior. Hint: We make behavior choices at every moment, and
Matching-to-sample
A conditional discrimination procedure in which a stimulus is presented and taught to match a secondary stimulus. Reinforcement is delivered for correctly matching the two antecedent stimuli. Matches can include
Maturation
Refers to the changes in a subject over the course of the study that result from natural growth and development.
Mean level line
A horizontal line on a line graph established by calculating the average of the graphed data points; used to signify the degree to which data points converge on the y-axis.

Measurement artifact
Data that represents an unwarranted and misleading picture of behavior because of how it was measured, typically a product of time-sampling, limiting measurement scales, or poorly scheduled measurement periods.
Measurement bias
When an observer’s measurement is influenced by an expectation or belief they hold rather than what actually occurred.
Measurement confounds
Uncontrolled variables related to the environment, the measurement tools, or a data collector’s behavior that may interfere with the measurement of behavior and therefore impact the outcomes and/or the effectiveness
Median level line
A horizontal line on a line graph established by calculating the median of the graphed data points, used to signify the degree to which data points converge on the y-axis.
