This stimulus set is similar to that used in an adult fMRI study of communicative auditory signals (Shultz et al., 2012) and a preferential looking paradigm assessing infant preferences for speech (Shultz & Vouloumanos, 2010) and has been well characterized in terms of its acoustic features.
"But the human brain shows no preference for speech.
In the Lasso procedure, it is difficult - if not impossible - to enforce a preference for speech atoms over noise atoms.
Such a strong response preference for speech over music (exactly that found in actors in the present study) is entirely absent in our group of violinists who showed equivalently robust activation for music as well as speech.
Interestingly, however, neonates do not show a preference for speech compared with rhesus monkey vocalizations, suggesting that neonates' listening biases may be relatively broadly tuned, encompassing a range of biological sounds, including conspecific and heterospecific vocalizations.
Although behavioral findings indicate that neonates' listening biases are sharpened over the first months of life, with a species-specific preference for speech emerging by 3 months, the neural substrates underlying this developmental change are unknown.
In individuals with DS a left-ear right-hemisphere preference for speech sounds (Hartley, 1981; Pipe, 1983; Bowler et al., 1985; Elliott and Weeks, 1993) or no ear advantage (Sommer and Starkey, 1977; Tannock et al., 1984) has been observed, instead of the typical right-ear left-hemisphere preference found in healthy controls.
In addition, brain processing of complex sounds is hierachical (for a review, see e.g., Griffiths 2001), and the well-known LH preference in speech processing is related to higher-order processing steps whereas steady-state responses reflect lower-level processing in the primary auditory cortex and its vicinity (Mäkelä & Hari 1987; Hari et al. 1989; Gutschalk et al. 1999).
Some differences based on the level of visual impairment were apparent for some of the output preferences such as speech type, speech format, obstacle warnings, etc.
