Table 1.

Mean diagnostic accuracy scores and standard deviations.

Condition	First impression	Strict (correct final diagnosis)	Lenient (correct diagnosis included in alternatives)
	M (SD)	M (SD)	M (SD)
Control (n = 64)	0.47 (0.26)	0.47 (0.26)*	0.47 (0.26)*
Short (n = 55)	0.49 (0.24)	0.42 (0.24)	0.70 (0.23)
Long (n = 57)	0.45 (0.24)	0.41 (0.26)	0.72 (0.25)

^*Under the control condition, the first impression diagnosis also constitutes the final diagnosis and no alternative diagnoses are offered. Therefore, the scores for the control condition under first impression, strict scoring and lenient scoring are all equal.
