Presentation time shapes perceived room size in visual and auditory modalities

Area of Science:

• Cognitive Neuroscience
• Psychology
• Auditory Perception

Background:

• Cross-dimensional interference between spatial and temporal processing offers insights into neuronal representations of space and time.
• Previous studies often show asymmetric interference, with temporal judgments more influenced by spatial information, potentially due to visual paradigms.
• This asymmetry has been hypothesized to diminish or reverse with auditory stimuli.

Purpose of the Study:

• To investigate the modality-specific effects on cross-dimensional interference between spatial and temporal processing.
• To test the assumption that auditory stimuli might alter the typical asymmetric interference patterns observed with visual stimuli.
• To explore the flexibility of space-time interference and its implications for the representation of time.

Main Methods:

• Participants judged either room size or duration using visual (virtual reality rooms) or auditory (reverberation-based sounds) stimuli.
• Acoustic reverberation was used to convey information about room size in the auditory modality.
• Interference patterns were analyzed by assessing how irrelevant temporal information affected spatial judgments and vice versa.

Main Results:

• In both visual and auditory modalities, judgments of room size were influenced by irrelevant temporal information.
• Judgments of duration remained unaffected by irrelevant spatial information across both modalities.
• The observed pattern of interference was not attributable to differences in task difficulty, as time judgments were consistently harder.

Conclusions:

• Space-time interference demonstrates significant flexibility, adapting to different sensory modalities.
• The findings challenge the long-held assumption that temporal representations are necessarily dependent on spatial representations.
• Auditory processing of spatial cues does not necessarily lead to a reversal of the typical interference asymmetry observed in visual paradigms.
