 Momentary time sampling is an observational technique that is used just kidding. I do actually know what momentary time sampling is It's just that sometimes the discriminative stimulus of a camera causes my brain to do nothing Anyway, so a momentary time sampling a measurement method in which the presence or absence of a particular behavior is recorded on a particular schedule and Not over a duration or counting a particular frequency you're just saying isn't happening at this moment And then so a momentary time sample, so maybe every 30 seconds you look up and go oh look my cameraman's being snarky And 30 seconds later I look back look he's being snarky and I record behavior or not Is he snarky is he not that sort of thing? Very useful in the classroom for teachers because they don't have time to record tons of behavior So you set up a momentary time sample with a kiddo that's got a problem behavior And you say all right every three minutes I want you to look at little Billy and see if he's on task or off task and make a note and that's it
