Figure 7. Mixed-effects response estimates.
The bars depict estimated average magnitudes (mixed-effects least squares means and their SEs) of reappearance-related overshoots (upper panels) and disappearance-related activation-dips (lower panels) for gaps, voluntary blinks and spontaneous blinks, occurring during face trials (left panels) and during non-face trials (right panels). Asterisks mark significant within-ROI simple effects (pFDR < 0.05 – *, pFDR < 0.01 – **, pFDR < 0.001 – ***). (a) Average reappearance-related overshoot magnitudes (face trials). (b) The same measurement for events occurring during non-face trials. (c) Disappearance-related activation-dips magnitudes (deeper activation-dips are more negative) during face-trials. (d) The same measurement for events occurring during non-face trials.

Figure 7—source data 1. Mixed-effect model outputs used to create Figure 7.
This excel workbook includes parameter estimates for each experimental condition and ROI as well as within-ROI simple effects, both calculated by lsmeans R package. Simple effects are accompanied with FDR-corrected p-values. Data for overshoot (Figure 7a,b) and dip components (Figure 7c,d) are provided in different excel spreadsheets.

Figure 7—figure supplement 1. Mixed-effects group analysis of gap and blink events matched for onset latency.
Only events occurring during face-trials were used. Asterisks mark significant FDR-corrected within-ROI simple effects (p<0.05 – *, p<0.01 – **, p<0.001 – ***, FDR-corrected). (a) Individual onset latency histograms of matched gaps and voluntary blinks. (b) The equivalent data for matched gaps and spontaneous blinks. (c) Average HFB reappearance-related overshoot magnitudes for the matched gaps and voluntary blinks (mixed-effects least-square means and their standard errors). Compare with Figure 7a – the same diminishing of the responses for voluntary blinks but not gaps is evident. (d) HFB reappearance-related overshoot magnitudes for the matched gaps and spontaneous blinks. Compare with Figure 7b. (e) Disappearance-related activation-dip magnitudes for matched gaps and voluntary blinks. Compare with Figure 7c. (f) Disappearance-related activation-dip for matched gaps and voluntary blinks. Compare with Figure 7d.
Figure 7—figure supplement 2. Mixed-effects group analysis of gap and blink events matched for duration.
Asterisks mark significant FDR-corrected within-ROI simple effects (p<.05 – *, p<.01 – **, p<.001 – ***, FDR-corrected). (a) Individual duration histograms of matched gaps and voluntary blinks. (b) The equivalent data for matched gaps and spontaneous blinks. (c) Average HFB reappearance-related overshoot magnitudes for the matched gaps and voluntary blinks (mixed-effects least-squares means and their standard errors). Compare with Figure 7a. (d) HFB reappearance-related overshoot magnitudes for the duration matched gaps and spontaneous blinks. Compare with Figure 7B. (e) Disappearance-related activation-dip magnitudes for the duration matched gaps and voluntary blinks. Compare with Figure 7c. (f) Disappearance-related activation-dip for the duration matched gaps and voluntary blinks. Compare with Figure 7d.
Figure 7—figure supplement 3. Controls for gap low-level properties.
The panels depict mixed-effects group analysis of responses to gap and spontaneous blink events, with control of the gap luminance (black or gray, panels a-b) or the gap temporal gradient (gradual or sharp, panels c-d). The values shown are mixed-effects least-square means and their standard errors. Asterisks mark significant FDR-corrected within-ROI simple effects (p<0.05 - *, p<0.01 - **, p<0.001 - ***, FDR-corrected). (a) Reappearance-related overshoot magnitudes for gray gaps, black gaps and spontaneous blinks (face-trials). Note how the gray gaps caused less low-level impact than blinks yet they still triggered a significantly greater response than blinks in high-level visual areas. (b) Reappearance-related overshoot magnitudes for gray gaps, black gaps and spontaneous blinks (non-face trials). (c) Reappearance-related overshoot magnitudes for gradual gaps (fading-in and out), sharp gaps (abruptly appearing) and spontaneous blinks (face-trials). (d) Reappearance-related overshoot magnitudes for gradual gaps (fading-in and out), sharp gaps (abruptly appearing) and spontaneous blinks (non-face trials).
