Abstract
Dual-process models of recognition memory typically assume that independent familiarity and recollec-tion signals with distinct temporal profiles can each lead to recognition (enabling 2 routes to recognition),whereas single-process models posit a unitary “memory strength” signal.

| Abstract: |
Dual-process models of recognition memory typically assume that independent familiarity and recollec-tion signals with distinct temporal profiles can each lead to recognition (enabling 2 routes to recognition),whereas single-process models posit a unitary “memory strength” signal. Using multivariate classifierstrained on spectral electroencephalogram (EEG) features, we quantified neural evidence for recognitiondecisions as a function of time. Classifiers trained on a small portion of the decision period performedsimilarly to those also incorporating information from previous time points indicating that neural activityreflects an integrated evidence signal. We propose a single-route account of recognition memory that iscompatible with contributions from familiarity and recollection signals, but relies on a unitary evidencesignal that integrates all available evidence. |
