This work proposes a parametric model for just noticeable differences of unilateral differences in head-related transfer functions (HRTFs). For seven generic magnitude-based distance metrics, common trends in their response to inter-individual and intra-individual HRTF differences are analyzed, identifying metric subgroups with pseudo-orthogonal be...

Listening to and remembering the content of conversations is a highly demanding task from a cognitive-psychological perspective. Particularly, in adverse listening conditions cognitive resources available for higher-level processing of speech are reduced since increased listening effort consumes more of the overall available cognitive resources. Ap...

Multisensory integration has mostly been studied with focus on perceptual effects. Only few examples exist that demonstrate multisensory enhancement, e.g., for object recognition, based on semantic integration, i.e., the combination of stimulus features to form a coherent perceptual representation of the object. However, it is unclear how these per...

In order to analyze, understand, and remember spoken language, multiple complex cognitive processes are involved. The field of cognitive psychology aims to quantify performance in such settings regarding, e.g., comprehension, listening effort, or verbal short-term memory. A well-established paradigm to examine short-term memory performance is the s...

Binaural hearing is a complex process that is significantly influenced by physical attributes of the listener. These dependencies on the shape of the torso, head, and pinna can be summarized in digital filters, so-called head-related transfer functions (HRTFs). Highly individual HRTFs are crucial for a realistic listening experience. However, in ma...

In the AUDICTIVE project about listening to, and remembering the content of conversations between two talkers we aim to investigate the combined effects of potentially performance-relevant but scarcely addressed audiovisual cues on memory and comprehension for running speech. Our overarching methodological approach is to develop an audiovisual Virt...
