Abstract:
Objective:To explore the cognitive processing characteristics of semantic emotion Stroop and memory recognition in pilots with depression, and to systematically reveal the cognitive processing characteristics of attention and memory.Methods:The semantic emotional Stroop task and memory recognition test were performed in 36 depressed pilots and 36 healthy pilots.The results of attention and memory in cognitive processing were analyzed by repeated measurement analysis of variance using SPSS 18.0 software.Results:In the semantic emotion Stroop, the response time of the depression group was longer than that of the control group ( F(1, 70)=7.03, P=0.008), and the response time of the depression group(579.55±141.62)ms ) was longer than that of the neutral words (565.66±132.60)ms, P=0.003) and positive words (563.09±138.88)ms, P<0.01). In memory recognition, the accuracy of response to emotion words in the depressed group was higher than that in the control group ( F(1, 70)=23.15, P<0.01). The accuracy of response to negative words was higher in the depressed group than that to positive words ((0.50±0.32) vs (0.32±0.21), P=0.006) and neutral words ((0.50±0.32) vs (0.33±0.23), P=0.007). The depression group showed a conservative bias towards negative words ((1.46±0.40), P<0.01), and negative words compared with neutral words ((0.63±0.24), P<0.01) and positive words ((0.57±0.27), P<0.01) were cautious and conservative. Conclusion:Patients with depression have attention bias toward the negative information in semantic information processing, and negative memory bias in memory recognition.
