“…Research has shown that these errors are not dependent on surface properties such as proximity (Bock & Cutting, 1992;Franck et al, 2002;Solomon & Pearlmutter, 2004;Vigliocco & Nicol, 1998) or phonological properties of the plural (Bock & Eberhard, 1993). Instead, these errors are particularly sensitive to syntactic manipulations (Bock & Eberhard, 1993;Franck et al, 2002;Vigliocco & Nicol, 1998), although they can also be affected by other more conceptual or semantic factors (e.g., Lorimor, Jackson, Spalek, & van Hell, 2016;Thornton & MacDonald, 2003;Vigliocco, Hartsuiker, Jarema, & Kolk, 1996). A critical characteristic of these errors is their asymmetry: They occur more often when the subject head is singular and the attractor noun is plural (e.g., "the key to the cabinets") than when both nouns have the same number (e.g., "the key to the cabinet" and "the keys to the cabinets") or when the head is plural and the attractor noun singular (e.g., "the keys to the cabinet").…”
