Change Effects, i.e., Frequency Jumps & Celeration Turns

NOTE 4/21/07--this information is currently being edited and is subject to correction


Roughly speaking change effects describe the effect of introducing

an intervention or change to intervention which constitutes a phase change

or a DOES in response to the IS conditions.(IS/DOES)


Jump is a change of frequency:increase or decrease that does not return to the previous frequency.

Turn is a change of celeration: increase or decrease that does not return to the previous celeration.


These changes are relatively stable, unlike Outliers or Bounce.

John W. Eshleman, Ed.D, BCBA has put together a nice description of

frequency jumps and celeration turns in his Blog,

NOTE: I found it helpful while listening to the presentation to open the blog entry in a SEPARATE window so that I could see the video, and have the larger chart blowup from the blog to examine while Rick was giving the video.
