Figure 6

Shows neural dynamics in DNF model underlying looking behavior during familiarization phase. Top row shows sum of PF activity while looking on each trial across the familiarization phase for the 5-month-old model (A), 7-month-old model (B), and 10-month-old model (C). PF activity was stronger for the 5-month-old model than the 7- or 10-month-old models. Error bars show +/− .5 SD.

Bottom row shows the state of PF and WM during the inter-stimulus interval after each familiarization trial, averaged across simulations. Neural interactions were weaker in the 5-month-old model (D), leading to stronger PF activity than in the 7- (E) and 10-month-old models (F) with stronger neural interactions. The stronger neural interactions of the older models gave rise to less total looking, higher shift rates, shorter look durations, and shorter peak looks relative to the weaker neural interactions in the younger model.
