<p><b>New page</b></p><div>This is a compiled timeline of insights, rated mental effort, and interactions from the Eric Fields observation. The timestamps are odd because the face video was running slightly faster than real time (due to me trying to do extended play on the camera). I had to manually sync the two videos up by comparing the screen visible in the face video with the screen capture. So when you see two timestamps, the first is the screen capture video and the second is the face video. After each five-minute timestamp is a self-reported mental effort rating from 0 to 9. Insights are timestamped using the face video.<br />

INSIGHT 03:57 - little smaller than predicted, not sure if stat sig<br />
<br />
INSIGHT 04:32 - main finding of the study<br />

INSIGHT 4:57 - no difference for the neutral phrases, not surprising.<br />
<br />
INSIGHT 5:00 - no difference for negative, which is a little surprising.<br />
<br />
INSIGHT 8:20 - something sig, what we were hoping for; confirm visual findings<br />
<br />
INSIGHT 8:39 - results are good because not a million different interactions being significant. (clean)<br />
<br />
INSIGHT 8:47 - effect is stronger in front than back... that's unexpected<br />

INSIGHT 13:15 same basic thing... front/back confusion.<br />
<br />
INSIGHT 14:55 something about late positivity.<br />
<br />
INSIGHT 15:53 difference in late positivity in emotions conditions (?) has a hypothesis, finds this interesting. sounds like a new interpretation of study<br />

INSIGHT 20:25 - effect is complicated because it differs across the scalp.<br />
<br />
'''38:00 / 20:52 - 7.5'''<br />
<br />
<br />
he's not actually staring at all, he's constantly changing parameters... even in the excel sheet he tends to scroll or click around when he's thinking hard.<br />
<br />
okay, so ~4 minutes EP to 5 minutes real world. <br />
<br />
mental effort as self rated steadily increases... even when he gets mired in SPSS errors<br />
<br />
lessons learned: need finer grained effort rating. post-hoc might help.<br />
<br />
stops interaction while thinking hard. what does that mean for this kind of study? <br />
<br />
meaningless interactions are common even tho his system isn't interactive. scroll, stare. <br />
<br />
got used to the mental effort rating after 3 iterations<br />
<br />
switching back and forth to answer questions... reminds me of jaime and dalia. <br />
<br />
swtiches views when he isn't sure about something.<br />
<br />
does rate higher in times of frustration... five-6 looked like a sweet spot. <br />
<br />
however, 15:53 ( at 7.5 or whatev) sounds like the meatiest insight so far. sounds like a research question for his followup study...<br />
<br />
how do i square stops interaction vs. switching intuition.. gotta check the screen cap.<br />
<br />
making the assumption that mental effort is pretty continuous, which is not a good assumption. ultimately fnirs might be a better idea...<br />
<br />
actually, here's a thing: whatever the absolute values are, the times of most insights are clearly associated with eric upping his mental effort rating. 1 insight, no change. 3+, it increases.</div>Caroline Ziemkiewicz
