더위때문에 파일럿 힘들었음 (에어컨 문제)
2nd session 힘들어 하는 아이들 있으나 that's expected

How about doing 2 sessions? -- one week interval, pay 50,000 only when you finish both sessions

ManyBabies 실험에 관해 주의할 점

2) infants who have participated in other studies *on the same day* are called _second session babies_ and they are OK, *but* you need to record that they are second-session AND the other study can’t be on IDS.

• Yes, I get that but I am not quite sure where to stop. E.g., if a baby starts fussing on trial 13, but then finally fusses out on trial 14 and we quit the experiment, do we include 13 and 14 or just stop at 12 when the baby was still behaving?
• We had a lot of discussion around this. Ideally, it would be great to get some level of subjective judgments around marginal trials, and even exclude based on fussiness centrally (to get a handle on what SHOULD be excluded for fussiness), but ultimately it was decided that this was just too difficult since everyone has different standards and protocols and ultimately without going back to the videos, it would be really hard to make the decisions centrally - the one who knows best what trials are useable is the person who ran the study (or coded the data after the fact). It's enough of a digression for some labs to even include partial data at all. So in the main data spreadsheet, JUST mark the point at which the fussiness reached exclusion levels (by which I mean the point that you decided the trial was sufficiently bad to start excluding). All trials from then on will be excluded. So if trial 13 was bad enough that you just the data no good, mark 13 and any subsequent trials you run as discard trials. But if 13 was "ok"/useable but that's when the baby "started" to lose it, then don't mark anything for that trial. Definitely hang onto those additional notes about fussiness in-lab if you have them though - maybe someone will come up with a good plan for a secondary analysis that looks at this in some meaningful way!!!!

• Do we have 'official' suggested wording for describing MB to parents when they're in the lab? as in, "In this study we're looking at..."  The question is whether we want to be fully informative about IDS vs. ADS or just say something more general. Thanks!
• There isn't an official wording. In my lab we say we're looking at how infants respond to the kind of speech that is typically used with babies versus the way we talk to adults. We don't tend to get into the details, but I wouldn't hide the details (including our expected findings) if the caregiver was asking direct questions. Since the caregiver is supposed to be blind (or rather, deaf) it shouldn't matter if they know.
