The 130–200 ms P7/P8 face–car EEG contrast was more negative for intact than scrambled images in 40 ERP CORE adults
We tested the face versus car EEG contrast in intact and scrambled images from 40 ERP CORE adults. The analysis used stored 250 Hz signals, P7/P8, and a fixed 130 to less than 200 ms window. The intact contrast minus the scrambled contrast was -1.22 microvolts, with an approximate 95% interval of -2.06 to -0.42 microvolts. A 20,000-draw bootstrap sampled persons and image pairs; its interval was 28.6% wider than the person-only interval. P8 alone and the 150–200 ms window had intervals that included zero. The SCI package retains the methods, analysis code, aggregate results, bootstrap draws, and figure. It links the dataset and task source because source event files, epochs, trial-level EEG values, and stimulus images are omitted under the archived source license terms. The result depends on the selected people, images, fixed measurement, and converted signals. It does not isolate a causal face mechanism.

We used its 40 all-stimulus P7/P8 epoch files and source event tables. We also used its source hashes and retrieval and extraction code. These files enabled the four-condition EEG contrast and the bootstrap that samples persons and images. Fresh source extraction checked every preserved array.

- usesWith fixed ERP CORE images, 130–200 ms P7/P8 face–car EEG agreement was lower after scrambled image subtraction within one visit in 39 adults
This work uses the preserved all-stimulus P7/P8 epochs, source event tables, image code mapping, and source audit. It adds first and second occurrence labels and compares paired agreement before and after scrambled image subtraction.
- usesThe early P7/P8 face–car peak time score had uncertain prediction gain in 39 ERP CORE adults from one visit
We used its pinned source manifest, event and channel tables, and original processing script. We retrieved the original 1024 Hz EEG files. We calculated new peak time scores and tested prediction across two parts of one visit.
- usesWith fixed images and one visit, the 95% interval included zero for the gain in P7/P8 face score correlation from shared images at 130–200 ms in 40 ERP CORE adults
We used its 40 all-stimulus P7/P8 EEG epoch files, artifact measures, source event tables, and processing code. We also used its 160 image files, task parameters, code map, and source hashes. These files enabled the comparison of shared-image and separate-image split correlations. Fresh source extraction matched every preserved EEG array.

This intermediate input supplied the inherited epoch processing and source notices through the immediate input package. We retained its metadata and license and used its fixed signal and artifact definitions.
- usesCell residuals gave 46.66% of added bootstrap variance in 40 complete ERP CORE N170 records
This publication supplied the preserved ERP CORE posterior epochs, source retrieval package, stimulus images, and task program. The new analysis retains all complete trials and audits exact bootstrap variance.

Uses the preserved N170 epochs, source event records, signal metadata, and image code map as direct inputs.
- usesStimulus code repetition was equal to a condition exposure step in all 40 ERP CORE N170 records
This source supplied the stored N170 task files, code-to-image map method, and image retrieval hashes. They enabled the source program check and the conditional image interpretation of repeated codes. A new pinned archive download matched the three stored task files exactly.

This work uses all 40 saved P7/P8 epoch records and the preserved task code map. It compares exact subset errors for the full saved contrast. It checks 300 preserved file hashes against this source publication.

This publication supplied the saved P7/P8 epochs, source event tables, image code map, and task program files. We used them to fit and test image models in separate people.

The stored task program, image code map, and image retrieval hashes came through f400e314-d4cd-4da4-92c4-dd8770803aa1. The map defined 160 shared codes and 80 intact and scrambled image families for matching and the split audit.

This publication supplied the preserved N170 task program and its image code mapping method. It also supplied context for the planned four-condition supporting check. We did not reuse its effect estimates.
