In daily life, humans are bombarded with visual input.
Yet, their perceptual capacities for processing this input are severely limited.
Several studies have investigated factors that influence these limitations and have identified methods to circumvent them.
In this talk, I present studies in multisensory research that have explored whether visual processing limitations can be circumvented by distributing processing across several sensory modalities.
Moreover, I discuss research from the field of joint action that has investigated how visual processing limitations can be circumvented by distributing task demands across co-actors. With regard to tasks that are performed alone, I will conclude that limitations can be circumvented by distributing processing across sensory modalities when tasks involve spatial as well as object-based perceptual processing.
Yet, if only spatial processing is required, processing limitations cannot be circumvented by distributing information processing across sensory modalities.
With regard to joint tasks, I will conclude that the benefits of distributing task demands across co-actors depend on the efficiency of collaborative strategies, the similarity between the co-actors’ individual performance capabilities, and the group size.
Taken together, the present work provides insights into how humans may process perceptual information more effectively in daily life and suggestions for several professions (e.g., air-traffic controllers) to optimize performance and reduce the risk of errors.
