“…Its limitation is that there was only limited power in detecting differences between the patient group and the HC group. Although similar sample sizes have been used in other studies [17,50], studies with larger samples characterized by a greater severity of symptoms could reveal stronger group differences in emotional experience and emotional working memory with regards to positive and negative emotional information. A further limitation of this study is that our results are based on cross-sectional data; therefore, we are unable to draw conclusions about causality.…”

“…Depressive patients have formed a negative cognitive schema in a chronic stress [44] or learned helplessness [45] environment, leading depressive patients to have a psychological conflict between processing positive external information stimuli and negative cognition, thereby affecting memory performance on positive information. Third, depressive patients have impaired attention, manifesting as insufficient attention to positive information and an attention bias for negative information [17,46]. Some studies have thought that non-depressed individuals have an attention preference for positive information as a "protective bias, " but depressive patients lack this "protective bias" [47,48].…”

“…Cognitive schema is a deep cognitive structure formed by an individual' s past experiences that dominates the individual' s information processing process (attention, selection, storage, and processing of information), which is to say that an individual tends to pay attention to, choose, and process information consistent with his own cognitive schema. According to the cognitive schema theory, depressive patients who are naturally depressed have a negative cognitive schema and prefer to pay attention to, choose, and perform refined processing on negative information [17], thus maintaining and developing their depressed mood. In this way, more focus is placed on mood-congruent information, and such information can better receive refined processing, thereby improving memory performance.…”

Journal of Psychiatry AbstractUsing an improved Sternberg working memory paradigm and affective pictures of different valences, this study investigates the emotional experience capability of 22 first-onset and untreated major depressive disorder patients (MDD) compared with the matching 22 healthy control participants (HC) and whether there is a moodcongruent working memory effect. We employed a general linear model analysis of variance (ANOVA) with two-factor repeated measures analysis on the emotional experience capability (pupil diameter changes) and the working memory performance (accuracy). The results show that the pupil diameter changes of positive emotions are significantly greater in MDD than those in HC (p<0.001), and the pupil diameter changes of negative emotions are not significantly different between two groups (p=0.055), which suggest that MDD have a significantly decrease in the ability to experience pleasure (anhedonia). In addition, the results only present that the working memory performances of negative emotions are significantly greater in MDD than those of positive emotions (p<0.05), which indicates that there is a mood-congruent memory effect. Moreover, in MDD, a positive correlation is found between the pupil diameter changes and working memory performances of positive emotions, however there is no correlation between those of negative emotions. Taken together, these results suggest that MDD have a moodcongruent memory effect and anhedonia, and the mood-congruent memory effect may be due to the decreased memory performances of positive emotions (a decrease in the ability to experience pleasure), but not those of negative emotions increased. This study not only illustrates that the core symptoms of depressive patients may be a mood-congruent memory effect and anhedonia but also enriches the connotation of anhedonia as an endophenotype indicator.

ResumenLos sesgos cognitivos juegan un papel importante como factores de vulnerabilidad en los trastornos emocionales. Recientemente se han empezado a desarrollar intervenciones para la Modificación de Sesgos Cognitivos (MSC), con el objetivo final de mejorar los síntomas clínicos. Aunque estos procedimientos innovadores se han utilizado más en los problemas de ansiedad, existe una investigación creciente sobre su uso en la depresión. En este trabajo efectuamos una revisión del marco teórico, los procedimientos utilizados y los principales resultados de la MSC en la depresión, en especial en la corrección de sesgos atencionales y de interpretación. Finalmente se analizan las limitaciones conceptuales y metodológicas de estas nuevas intervenciones y se discuten sus implicaciones clínicas, teóricas y aplicadas. Palabras clave: Modificación de sesgos cognitivos (MSC), sesgos cognitivos, intervenciones cognitivas y depresión. AbstractCognitive biases play an important role as vulnerability factors in emotional disorders. Interventions for Cognitive Bias Modification (CBM) have recently begun to be developed with the ultimate goal of improving clinical symptoms. Although these innovative procedures have been applied mainly in anxiety problems, there is increasing research on the application in depression. This work reviews the theoretical framework, the procedures used, and the main results of CBM in depression, especially in the modification of attention and interpretative bias. Finally the conceptual and methodological limitations of these promising interventions procedures are analyzed as well as the clinical, theoretical and applied implications.

“…Therefore, the changing of pupil is a sign of the activity of central nervous system. Data shows that the patients of depression with the features of gazing the positive emotional information (such as happy expression) less and gazing negative emotional information (such as sad expression) frequently [5]. Accordingly, we can know people's emotional state by tracking the attention of a person's bias attention, the rate of pupil diameter, the saccadic slope and other visual information.…”

Abstract. At present, the clinical diagnosis of depression is mainly through structured interviews by psychiatrists, which is lack of objective diagnostic methods, so it causes the higher rate of misdiagnosis. In this paper, a method of depression recognition based on SVM and particle swarm optimization algorithm mutation is proposed. To address on the problem that particle swarm optimization (PSO) algorithm easily trap in local optima, we propose a feedback mutation PSO algorithm (FBPSO) to balance the local search and global exploration ability, so that the parameters of the classification model is optimal. We compared different PSO mutation algorithms about classification accuracy for depression, and found the classification accuracy of support vector machine (SVM) classifier based on feedback mutation PSO algorithm is the highest. Our study promotes important reference value for establishing auxiliary diagnostic used in depression recognition of clinical diagnosis.
