Abstract

fetched live from OpenAlex

In this psychological refractory period (PRP) experiment, a tone (T1) was presented, followed by a visual target (T2) embedded in a bilateral display, and a speeded response was required for each target. The T1-T2 stimulus onset asynchrony (SOA) was 300, 650, or 1000 ms. Mean response time to T2 increased as SOA was reduced, replicating the well-known PRP effect. Importantly, the N2pc component of the event-related potential was progressively attenuated as SOA was reduced, and the onset latency of the sustained posterior contralateral negativity (SPCN) that follows the N2pc was progressively lengthened. Conditional analysis based on Task1 difficulty corroborated the analyses based on effects of SOA. The results suggest that central processing leading to the PRP effect interferes with the deployment of visual-spatial attention (as indexed by the N2pc) and delays encoding into visual short-term memory (as indexed by the SPCN onset latency).

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
