Habituation

PreviousJUMPNextSetting habituation criteria

Last updated 4 years ago

Habituation studies are ones in which an experiment or phase continues until the child no longer attends (or attends less) to a particular stimulus.

In BITTSy, habituation phases terminate based on your protocol's set termination criteria - a decrease in looking relative to baseline. This, in turn, is based on the following factors:

  • How many trials should be included in the baseline measure and in judging whether habituation has occurred (e.g., 3 trials, 4 trials, etc.). Note that the window SIZE (in terms of number of trials) is the same for both.

  • Which trials are included in the baseline (e.g,. the FIRST three trials, or the 3 trials with LONGEST looking overall...)

  • Percentage drop (e.g., the phase should end when looking has reduced by a certain percentage of baseline, such as 50% of baseline looking)

See the other pages in this section for specifics on how to , and proceed to another phase of the experiment, or that do not meet desired criteria.
