Table 3.

Proportion ‘valid’ responses for Experiment 1. Mean proportions ‘valid’ responses as a function of inference type (valid or invalid), presence of NPI (+ for present, − for absent) and NPI type (ever or any). Standard deviations (SDs) in parentheses. Proportions correct for (a) and (b) are equal to the tabulated value, but proportions correct for (c) and (d) are equal to 1 minus the tabulated value

	(a)Valid, NPI+	(b)Valid, NPI−	(c)Invalid, NPI+	(d)Invalid, NPI−
any	0.89 (0.17)	0.87 (0.14)	0.51 (0.31)	0.38 (0.31)
ever	0.85 (0.18)	0.87 (0.20)	0.46 (0.31)	0.44 (0.37)
Total	0.87 (0.13)	0.87 (0.14)	0.49 (0.29)	0.42 (0.33)
