Minimum audible angle (MAA) thresholds are compared for several studies. Panel A includes data from children. Triangles show data from 5-year old normal-hearing children (modified from Litovsky, 1997). In addition, there are two sets of data from studies in which BiCI users were tested in bilateral (filled circle) vs unilateral listening modes (open circle). In one study children ranged in age from 3.5 to 16 (modified from Litovsky et al., 2006), and in a second study children ranged in age from 5-10 years (modified from Godar and Litovsky, 2010) Panel B includes MAA threshold data from toddlers who were approximately age 2.5 years at the time of testing. Triangle show data from normal-hearing children, filled circles show data from BiCI users who fell into two groups, and open circles how data from unilateral CI users (modified from Grieco-Calub et al., 2008).
