Contrasting linguistic and nonlinguistic processing has been of interest to many researchers with differentscientific, theoretical, or clinical questions. However, previous work on this type of comparativeanalysis and experimentation has been limited. In particular, little is known about the differences andsimilarities between the perceptual, cognitive, and neural processing of nonverbal environmentalsounds and that of speech sounds. With the aim of contrasting verbal and nonverbal processing in theauditory modality, we developed a new on-line measure that can be administered to subjects from differentclinical, neurological, or sociocultural groups. This is an on-line task of sound to picture matching,in which the sounds are either environmental sounds or their linguistic equivalents and which iscontrolled for potential task and item confounds across the two sound types. Here, we describe the designand development of our measure and report norming data for healthy subjects from two differentadult age groups: younger adults (18?24 years of age) and older adults (54?78 years of age). We also outlineother populations to which the test has been or is being administered. In addition to the results reportedhere, the test can be useful to other researchers who are interested in systematically contrastingverbal and nonverbal auditory processing in other populations.
