Description: This study introduces normative ratings for 550 Spanish word pairs across six theoretically motivated semantic dimensions: category membership, synonymy, antonymy, functional relatedness, perceptual similarity, and concept–property relation. Each dimension was independently rated by 100 native Spanish speakers using a 7-point Likert-type scale. Word pairs were derived from a graded backward-association corpus originally developed for false-memory research in the DRM paradigm. To ensure comprehensive coverage, each pair was evaluated in both possible word orders across balanced sub-blocks. For every semantic dimension, detailed ratings are reported per pair and participant, alongside demographic data.
