“…In addition, a large body of research in the field of joint action has shown that individual task performance is affected by performing visual perceptual tasks jointly (Böckler et al, 2012; Karlinsky et al, 2017; Knoblich & Sebanz, 2006; Saunders et al, 2018; Sebanz et al, 2003, 2006; Sellaro et al, 2020; Vesper et al, 2017; Yamaguchi et al, 2018). For instance, Sellaro et al (2020) investigated the effects of joint task performance in a visual picture-word interference task.…”

Our senses are stimulated continuously. Through multisensory integration, different sensory inputs may or may not be combined into a unitary percept. Simultaneous with this stimulation, people are frequently engaged in social interactions, but how multisensory integration and social processing interact is largely unknown. The present study investigated if, and how, the multisensory sound-induced flash illusion is affected by a social manipulation. In the sound-induced flash illusion, a participant typically receives one visual flash and two auditory beeps and she or he is required to indicate the number of flashes that were perceived. Often, the auditory beeps alter the perception of the flashes such that a participant tends to perceive two flashes instead of one flash. We tested whether performing a flash counting task with a partner (confederate), who was required to indicate the number of presented beeps, would modulate this illusion. We found that the sound-induced flash illusion was perceived significantly more often when the flash counting task was performed with the confederate compared with performing it alone. Yet, we no longer find this effect if visual access between the two individuals is prevented. These findings, combined with previous results, suggest that performing a multisensory task jointly—in this case an audiovisual task—lowers the extent to which an individual attends to visual information, which in turn affects the multisensory integration process.
