Memory and text comprehension for text spoken by two talkers alternatingly – examining the potential roles of talkers’ spatial location

Zusammenfassung:When listening to a conversation of several talkers in real-world, the heard audio signal has inherent spatial information of the different talkers’ positions, whereas this holds not true in, e.g. telephone conferences. The aim of the study was to investigate, whether the auditory-perceptive availability of spatial information helps or hinders cognitive performance in terms of remembering of heard information. To this end, we investigated short-term memory for text spoken by two talkers alternatingly. These talkers were either auralized binaurally at two different positions in space (60° relative to the listener) or were colocated (0°). Additionally to performance in the listening task (primary task), participants worked also on a visually presented secondary task (cross-modal dual-tasking). Performance in this secondary task served as an indicator of cognitive spare capacity: The higher the cognitive burden in the listening task (primary task), the more performance decline on the secondary task . With this, memory and text comprehension measures in the listening task as well as secondary task performance allowed us to gain insight into the cognitive affordances of listening to two alternating talkers auralized at different spatial locations or colocated.
