Directed attention is an important process involved in cognitive functioning. Mental fatigue from daily tasks often leaves a persons directed attention depleted. According to Attention Restoration Theory (ART), exposure to natural stimuli can restore directed attention. Although many studies have investigated the ability of natural visual stimuli to restore attention, research exploring the restoration provided by natural auditory stimuli is lacking. With an abundance of sounds found in nature, bird sounds are among the most prevalent. This study aimed to investigate the differences in restoration experienced after listening to sounds from different avian species compared to a control of listening to silence. It was expected that different species would provide varying measurements of attention restoration due to differences in the sounds each species makes. Two species of birds, the common house sparrow (P. domesticus) and the black-billed magpie (P. hudsonia) were selected based on their perceived restoration potential (PRP) score determined by Ratcliffe et al. 2016. All participants first took the sustained Attention to Response Task (SART) to place a demand on attention. Participants then listened to a recording of one of the two species or silence and immediately took the Attention Network Test (ANT) to measure the restorative effects on directed attention. Another group of participants took the ANT to serve as a baseline measure. There was no significant difference of attention interference observed between groups who listened to bird sounds or silence however, the group who only took the ANT exhibited greater interference from distractions that the group who sat in silence. These results indicate that listening to bird sounds may have a positive influence on attention restoration and spending an equal amount of time in silence may have a similar effect.
