Table 2

Matching variables for LT and NLT stimuli (means and standard deviation, in brackets).

	LT	NLT
AoA	4.2 (1.3)	4.5 (1.5)	.5
Fam.	3.1 (0.9)	3.1 (1.1)	.9
LF	14.7 (1.2)	14.7 (2.5)	.9
NA	0.5 (0.3)	0.6 (0.3)	.6
Prot.	3.5 (0.9)	3.3 (1.1)	.4
VC	2.7 (0.7)	2.9 (0.8)	.2

Note. AoA = age of acquisition, fam. = familiarity, LF = lexical frequency, NA = name agreement, prot. = prototypicality, VC = visual complexity, LT = living things, and NLT = nonliving things.
