| 背景 前瞻记忆是指在未来某个时间执行某个计划的能力，前瞻记忆的改善有助于抑郁症患者回归社会，因此本研究以目标特征（情绪效价和凸显性）为自变量，探讨其对抑郁症患者前瞻记忆的影响，为临床治疗提供借鉴。方法 招募45名抑郁症患者和45名健康者为被试，采用2（被试类型:抑郁组、健康组）×2（目标凸显性:凸显、不凸显）×3（情绪效价:正性、中性、负性）三因素混合实验设计，采用双任务实验范式，记录不同目标特征前瞻记忆的反应时和正确率。结果 ①被试类型主效应有统计学意义，抑郁组正确率低于健康组（F=14.89，P＜0.01），抑郁组前瞻记忆反应时慢于健康组（F=10.64，P＜0.01）。②目标情绪效价正确率（F=7.58，P＜0.01）和反应时（F=3.19，P＜0.05）主效应有统计学意义，简单效应显示抑郁组负性目标的反应时快于正性目标（F=17.20，P＜0.01）、正确率高于正性目标（F=12.97，P＜0.01），健康组正性目标的反应时快于负性目标（F=7.84，P＜0.01）。③目标凸显特征主效应有统计学意义，凸显目标的正确率高于不凸显目标（F=6.66，P＜0.05）、反应时快于不凸显目标（F=10.11，P＜0.01）。结论 抑郁症患者对负性前瞻记忆目标优先注意和优势加工；目标凸显性促进抑郁症患者对前瞻记忆任务的自动化加工。 |

| Background Prospective memory refers to the ability to carry out a plan at a certain time in the future, and the improvement of prospective memory can help depressed patients return to society. Previous studies have not reached a consensus on the influence of target characteristics on prospective memory, so the impact of target characteristics (emotional titer and salience) on prospective memory of depressed patients is discussed. Methods 45 depressed patients and 45 healthy subjects were recruited as subjects. A three-factor mixed experimental design of 2 (subjects type: depressed group, healthy group) ×2 (target prominence: prominent, not prominent) ×3 (emotional titer: positive, neutral, negative) was adopted, and the response time and accuracy of prospective memory with different target characteristics were recorded by double-task experimental paradigm. Results ① The main effect of the subject type was statistically significant. The correct rate of the depressed group was lower than that of the healthy group (F=14.89, P < 0.01), and the prospective memory response of the depressed group was slower than that of the healthy group (F=10.64, P < 0.01). ②The main effect was statistically significant (F=7.58, P < 0.01) and reaction time (F=3.19, P < 0.05). Simple effect showed that the reaction time of negative target was faster than that of positive target (F=17.20, P < 0.01), and the correct rate was higher than that of positive target (F=12.97, P < 0.01). In the healthy group, the response time of positive target was faster than that of negative target (F=7.84, P < 0.01). ③ The main effect of target prominence features was statistically significant, and the correct rate of target prominence was higher than that of unhighlighted target (F=6.66, P < 0.05), and the response time was faster than that of unhighlighted target (F=10.11, P < 0.01). Conclusion The patients with depression give priority attention to the negative prospective memory goals and process them preferentially. Target salience promotes automatic processing of prospective memory tasks in depressed patients. |
