Numerous studies have found better memory for multimodal than unimodal stimuli. In these studies, however, multimodal stimuli consist not only of multiple modalities, but also of more varied information than unimodal. Therefore, in the present study, we investigated encoding variability as an explanation for the multisensory benefit. Written words…

The modality effect refers to the robust finding that memory performance differs for items presented aurally, as compared with visually. Whereas auditory presentation leads to stronger recency performance in immediate recall, visual presentation often produces better primacy performance (the inverse modality effect). To investigate and model these…

Three source-memory experiments were conducted with Spanish-English bilinguals and monolingual English speakers matched on age, education, nonverbal cognitive ability and socioeconomic status. Bilingual language proficiency and dominance were assessed using standardized objective measures. In Experiment 1, source was manipulated visuo-spatially,…

Three experiments examined the immediate free recall (IFR) of auditory-verbal and visuospatial materials from single-modality and dual-modality lists. In Experiment 1, we presented participants with between 1 and 16 spoken words, with between 1 and 16 visuospatial dot locations, or with between 1 and 16 words "and" dots with synchronized…

In 5 experiments, a Hebb repetition effect, that is, improved immediate serial recall of an (unannounced) repeating list, was demonstrated in the immediate serial recall of visual materials, even when use of phonological short-term memory was blocked by concurrent articulation. The learning of a repeatedly presented letter list in one modality…

In 2 experiments, the authors tested whether the classical modality effect--that is, the stronger recency effect for auditory items relative to visual items--can be extended to the spatial domain. An order reconstruction task was undertaken with four types of material: visual-spatial, auditory-spatial, visual-verbal, and auditory-verbal.…
