Some things we need to discuss next meeting:

• [x] vanilla trials and stimuli are a bit of a mess (groups variable can give clue?)
• [x] cdi data has columns that could be referring to something different (probably not though)
• [x] should we implement a cutoff for timepoints/frames after which very little hancoded data exists?
• [x] should NA values in the "aoi" column translate to "missing", NA, or should they be filtered out?
• [x] are there images for this?

[mzettersten]

• don't worry about images (non-trivial to dig up)
• trials are pretty much consistent with how we guessed in our meeting:
  • 18 months:
    • whole: vanilla (just regular trials)
    • yfill: also vanilla
    • gated: these are the "cut off" words, non-vanilla
    • zteach: this is a teaching trial in which a novel object is mapped to a novel label (nonce or kreeb) - non-vanilla
    • (a)learn: this is a test trial for the novel labels - non-vanilla
  • 21 months:
    • xfacil: these are trials in which the verb facilitates the recognition of the label ("eat the cookie") - non-vanilla
    • whole: regular vanilla trials
    • look: these are matched to the xfacil trials, e.g. "Look at the cookie" instead of the xfacil trial "eat the cookie". These are vanilla, with the caveat that I'm not entirely sure where F0 is set within the trial (beginning of the trial or onset of cookie?). We should look carefully at these specific trials to clear this up.
    • gated: as before, non-vanilla (truncated words)
    • new: these are mutual exclusivity-style trials, non-vanilla
    • ylearn: novel word trials, non-vanilla
  • 25 months: all as before, with the following changes:
    • losse: this is like "gated", non-vanilla
    • hard: vanilla - this just means that the specific words were "harder"
    • nice/super/pretty/none - all vanilla; these just mean that an additional adjective was shown (except for the none trials, these are just paired with the pretty trials e.g.), but I think it is safe to consider these all vanilla for our purposes. Let's also have a close eye on the timing of the curve inflection for these, just to make sure the points of disambiguation are right

[mzettersten]

• NA in the aoi column should typically be "missing"
• some kind of percentage cutoff (<1%?) would be reasonable to standardize
• I think the CDI data should be straightforward:
  • und12new, und15new: comprehension for CDI W&G at 12 months and 15 months
  • said12, vocab15: production for CDI W&G at 12 months and 15 months
  • vocab18, vocab21, vocab25: CDI words and sentences (production) at 18, 21 and 25 months
  • vocper18/21/25: corresponding percentile scores
  • compl18, complx21, complx25: grammatical complexity measure at 18, 21, 25 months (see paper for details)

[adriansteffan]

• [x] what is a "toma"? a novel word?
• [x] same as with adams marchman: The timing of the looking score time graph looks off both before AND after the resampling/rezeroing/norming, being to early and too late respectively. A second pair of eyes could help here
• [x] check the outlier conditions (super, yfill) - need another set of eyes, there does not seem to be any obvious anomaly other than the scores being abnormally high/low. (shifts/stretching of the time axis was a hypothesis, but all data starts at t=0, so that can probably be ruled out)
• • yfill are 9 18 months old, so that might explain something
• • super are 58 25 month olds, so that one is a headscratcher (decision: filter out super for now until we find an explanation, yfill is likely caused by low n/age)

[mcfrank]

Yes, a toma is definitely a novel word!
