TL;DR: In this paper, a foreign language was presented over earphones while subjects performed a serial recall task with visual presentations and written recall, and the presence of the irrelevant foreign language noise reduced recall performance on phonologically different lists but it did not reduce performance on similar lists.

TL;DR: A key size of 20 mm was found to be sufficiently large for land-on key entry and preferred 20 mm keys to smaller keys, and participants were indifferent between 20 and 25 mm keys.

TL;DR: In four experiments, both the spatial location of speech noise and its intensity were systematically varied to determine how they influenced recall, and the results were consistent with the assumption that primary memory masking takes place in the preperceptual auditory store, which has been inferred from backward recognition masking studies, but were inconsistent from modality and suffix studies.

TL;DR: A dual mode model was proposed that assumes that survey knowledge may be quickly acquired for local regions and accurate metric spatial information was available for objects in the same room, supporting an early acquisition assumption.

TL;DR: It is recommended that methods for standardizing context, such as providing experience with the complete difficulty range, be developed for subjective mental workload evaluations to increase the validity of subjective measures.
