The Effect of Task-Irrelevant Fearful-Face Distractor on Working Memory Processing in Mild Cognitive Impairment versus Healthy Controls: An Exploratory fMRI Study in Female Participants

Table 2

Summary of behavioral data related to accuracy of response and reaction time (RT).

Condition	Performance	MCI		HC
		Mean	SD	Mean	SD
4-letter fearful	Accuracy	87.9%	14.7	95.2%	5.6
	RT	1450	204	1357	239
4-letter neutral	Accuracy	90.7%	10.7	93.5%	7.1
	RT	1456	169	1357	270
2-letter fearful	Accuracy	92.9%	13.1	92.9%	13
	RT	1304	281	1153	222
2-letter neutral	Accuracy	90%	9.7	96%	4.9
	RT	1277	219	1144	218

Data was expressed in percentage of accurate responses and milliseconds for RT. A mixed model ANOVA did not identify any significant effects of group, emotion, or loading on accuracy of response while RT was affected only with loading in both groups but with no significant effect of group or emotion.
