Although some studies have shown that individuals with early-onset blindness do not perform differently from those who are sighted in odor-threshold and simple chemosensory tasks, such as the discrimination of odors (Diekmann, Walger, & Von Wedel, 1994; Schwenn, Hundorf, Moll, Pitz, & Mann, 2002; Smith, Doty, Burlingame, & McKeown, 1993), other studies have provided evidence that persons with early-onset blindness outperform age-matched sighted persons in more complex tasks of olfactory identification, such as free identification (Cuevas, Plaza, Rombaux, De Voider, & Renier, 2009; Murphy & Cain, 1986; Rosenbluth, Grossman, & Kaitz, 2000), particularly when semantic aspects are involved (Wakefield, Homewood, & Taylor, 2004).
