The effect of personality characteristics combined with behavioral activation system (BAS) / behavioral inhibition system (BIS) and sport emotional induction on working memory

Abstract Study aim: To investigate the interactive effects of behavioral activation or behavioral inhibition and induced pleasant or unpleasant emotions on working memory performance among young adults. Material and methods: Eighty participants (age 18–32 years) were randomly classified into 2 groups behavioral activation or inhibition and then sub-divided further via whether they received inductions in either pleasant emotions or unpleasant emotions. A pre-test measure of the working memory test was recorded and repeated after emotional induction. Results: The ANOVA analysis indicated significant effect of PERSONALITY factor (F1,76 = 4.760, p = 0.0322, ηp 2 = 0.059) on results of the working memory test. The memory performance of the behavioral activation group that received positive emotion was better than the other groups, and the working memory performance of the behavioral inhibition group that received positive emotion was poorer than the other groups. Furthermore, the working memory performance of the behavioral activation group (positive emotion) was better than the other groups. Also, the working memory performance of the behavioral inhibition group (positive emotion) was poorer than the other groups. Conclusions: Finally, the findings support the different effects of the brain behavioral systems and sport emotional induction on working memory.

Information on Covid-19 and Effortful Control Level: Increasing or Decreasing Anxiety?

Anxiety has increased with more information about the COVID-19 outbreak. The COVID-19 information can make people more aware and care about this pandemic. However, it also can make people feel panic and anxious. Emotional induction in the information is referring to how the emotion carried by the information can affect early adult’s anxiety, but the differences in effortful control level that each person has also define the level of anxiety someone experiences. The anxiety level related to effortful control is one dimension of temperament. This study is conducted in concern of the effect of emotional induction in COVID-19 information towards anxiety in high and low effortful control groups. This study used a quantitative method with quasi-experimental research. This study involves 218 early adults in an age range of 20-40 years old. This study used pictures from content information about COVID-19, Self-Assessment Manikin (SAM), Beck Anxiety Inventory (BAI), and Effortful Control Questionnaire (ECQ) as the measuring tools. The results of the significance test show p <0.005. This means that there is an effect of emotional induction on anxiety at both high and low effortful control levels. This study shows that emotional induction in the form of COVID-19 information reduces anxiety in the respondent group with a high level of effortful control, but increases anxiety in the respondent group with a low level of effortful control. The effect of COVID-19 information on anxiety based on effortful control in the late adult (over 65 years old) group, in this study cannot be explained.

Predicting the effectiveness of engagement and disengagement emotion regulation based on emotional reactivity in borderline personality disorder

ABSTRACT Improving emotion regulation is central to borderline personality disorder (BPD) treatment, but little research indicates which emotion regulation strategies are optimally effective and when. Basic emotion science suggests that engagement emotion regulation strategies that process emotional content become less effective as emotional intensity increases, whereas disengagement strategies that disengage from it do not. This study examined whether emotional reactivity to emotional stimuli predicts the effectiveness of engagement and disengagement emotion regulation across self-report, general physiologic (heart rate), sympathetic (skin conductance responses), and parasympathetic (respiratory sinus arrythmia) emotion in BPD, healthy, and clinical control (i.e. generalized anxiety disorder; GAD) groups. 120 participants (40 per group) were exposed to emotion inductions and then instructed to implement engagement (mindful awareness) and disengagement (distraction) strategies while self-report and physiological emotion measurements were taken. In the BPD and GAD groups, higher heart rate or respiratory sinus arrythmia reactivity, respectively, predicted improved mindful awareness effectiveness. Higher skin conductance reactivity predicted worsened distraction effectiveness in BPD. Higher reactivity may potentiate engagement emotion regulation, and exacerbate disengagement from emotional content, in BPD. Future research should examine other domains of emotion regulation that may be influenced by emotional intensity, and other forms of emotional intensity that may influence them.

Learning from gain and loss: Links to suicide risk

Despite preliminary evidence that people with suicide attempt histories demonstrate deficits in processing feedback, no studies have examined the interrelations of learning from feedback and emotional state on suicide risk. This study examined the influence of suicide risk and negative emotions on learning accuracy and rates among individuals with a range of borderline personality features (N = 145). Participants completed a reinforcement learning task after neutral and negative emotion inductions. Results revealed interactions between suicide risk and emotion condition, with elevated risk linked to greater increases in loss learning rate (training phase models) and gain learning rate (test phase models) post-negative emotion induction. Emotion-dependent fluctuations in learning performance may be markers of decision-making that are associated with greater suicide risk. This line of work has the potential to identify the contexts that confer greater risk for suicidal behaviors.

The effects of subliminal or supraliminal sadness induction on the sense of body ownership and the role of dissociative symptoms

Previous research has shown that emotions can alter our sense of ownership. Whether this relationship is modulated by differences in emotion experience and awareness, however, remains unclear. We investigated this by comparing the susceptibility to the rubber hand illusion (RHI) between participants who were either exposed to a low-arousing emotion induction (sadness) or placed in a neutral control group. Several factors that might influence this relationship were considered: dissociative symptoms were included to observe if a sadness induction led to a higher RHI score in participants scoring high in dissociation, as a result of detached emotion experience. Whether the level of awareness of the emotion mattered was also tested, as subliminal processing was shown to require less focal attention. Therefore, our sample (N = 122) was divided into three experimental groups: Sad pictures were presented to two of the three groups differing in presentation mode (subliminal: n = 40, supraliminal: n = 41), neutral pictures were presented supraliminally to the control group (n = 41). Additionally, the effects of slow (3 cm/s) and fast (30 cm/s) stroking, applied either synchronously or asynchronously, were examined as the comforting effects of stroking might interfere with the emotion induction. Results showed that the supraliminal sadness induction was associated with a stronger subjective illusion, but not with a higher proprioceptive drift compared to the subliminal induction. In addition, a stronger subjective illusion after fast and synchronous stroking was found compared to slow and asynchronous stroking. A significant proprioceptive drift was detected independent of group and stroking style. Both slow and synchronous stroking were perceived as more comforting than their respective counterparts. Participants with higher dissociative symptoms were more susceptible to the subjective illusion, especially in the supraliminal group in the synchronous condition. We concluded that individual differences in emotion experience are likely to play a role in body ownership. However, we cannot clarify at this stage whether differences in proprioception and the subjective illusion depend on the type of emotion experienced (e.g. different levels of arousal) and on concomitant changes in multisensory integration processes.

Long-range correlation analysis of high frequency prefrontal electroencephalogram oscillations for dynamic emotion recognition

Numerous previous studies have proved the enormous potential of high frequency EEG in emotion recognition, however, the current existing EEG analytic methods are not so effective when dealing with high frequency oscillations. Therefore, a novel refined-detrended fluctuation analysis method multi-order detrended fluctuation analysis (MODFA) was proposed. The best fitting order is selected according to the inflection point in the dependence degree curve of high frequency EEG and multi-order polynomial. MODFA measures the power-law long-range correlation of high frequency nonlinear signals. Prefrontal EEG signals were recorded during six emotion-inducing tasks (neutral, fear, sad, happy, anger, and disgust). To confirm the susceptibility and efficiency of MODFA indices, including hurst-exponent MODFA-h1 and intercept MODFA-a1, on emotion recognition, we compared MODFA with original detrended fluctuation analysis, as well as the conventionally used fuzzy entropy (FE) and power spectral density (PSD) on high frequency EEG oscillations (62.50–93.75 Hz). The results showed that MODFA achieved the best performance in binary emotion classification (positive and negative, accuracy = 96.81%), ternary classification (neutral, positive, and negative, accuracy = 76.39%), and six-classification (accuracy = 42.17%). Moreover, along with inducing time, the cumulative effects of the four negative emotions (fear, sad, anger, and disgust) were observed by MODFA-a1, FE, and PSD, which demonstrated that the accumulation of negative emotions are associated with the prefrontal lobe and could be measured via high frequency gamma rhythms. These findings indicated the nonlinear dynamics of high frequency brain activity during emotion induction, and the prefrontal EEG-based emotion recognition might have great application prospect in real-life practice.

Impact of emotionally-charged images and trial order on downstream cognitive processing: An ERP study

Theories of emotion-cognition interactions suggest that emotional valence can both facilitate or limit cognitive performance. One cause for the mixed findings may be the order (random versus non-random presentation) in which emotional stimuli are presented. To investigate the impact of stimuli order on cognitive control processing, EEG data were recorded as 130 undergraduate students (M age = 22.2, SD = 5.4; 79 female) completed a modified version of the AX-Continuous Performance Task in which the cue was followed by an emotionally-valenced image (positive, negative, and neutral). Specifically, the task was designed so that valenced images were presented in either a block or random order, prior to probe presentation. We examined two event-related potentials (ERPs), the N2, which reflects aspects of cognitive control, and the late positive potential (LPP), which reflects attention allocation to emotional stimuli. We assessed the impact of emotionally oriented attention (LPP) on downstream cognitive control (N2) and how this relationship might differ for a block versus random (order of emotional image) task design. Consistent with the LPP literature, we found a main effect of image valence with the negative trials showing larger LPPs than the positive and neutral trials. For N2s, we found that the negative trials were associated with smaller N2s than both the positive and neutral trials. We observed that as LPP amplitude increased, subsequent N2 amplitude was reduced, specifically for negative trials in the random design. These results suggest an emotion-related depletion of neural cognitive resources. Lastly, we found larger N2s for the block design versus the random design. Together, these results indicate the importance of paying attention to both trial order (block versus random) and within trial stimulus sequence when designing emotion induction tasks.

Animal Signals, Music and Emotional Well-Being.

Simple SummaryAnimal signals can convey information about the animal’s state, but these signals can also be used to influence the behavior of others through emotional contagion. Music can influence the emotional state of human listeners and has also been used therapeutically with a variety of captive species including pets. However, the successful use of music to influence the well-being of animals must be based on an understanding of the natural communication signals of the species including the frequency range and tempos of its own communication signals. Furthermore, different types of music can induce different emotional states. In this paper, I review work using music to influence animal emotion, physiology and behavior, and I outline a theory of emotional induction that predicts what types of music stimuli are likely to influence different emotions and behavior. I will illustrate this with some examples of animal-based music. The use of music to influence the emotional well-being of our pets, farm animals and in zoological parks depends on our understanding the communication system of other species and the variety of emotional states that can be induced through different types of music. My goal is to help those managing animal facilities or advising pet owners to be more aware of the issues involved in using music with animals, as well as provide advice to researchers investigating effects of music on animals.Playing music or natural sounds to animals in human care is thought to have beneficial effects. An analysis of published papers on the use of human-based music with animals demonstrates a variety of different results even within the same species. These mixed results suggest the value of tailoring music to the sensory systems of the species involved and in selecting musical structures that are likely to produce the desired effects. I provide a conceptual framework based on the combined knowledge of the natural communication system of a species coupled with musical structures known to differentially influence emotional states, e.g., calming an agitated animal versus stimulating a lethargic animal. This new concept of animal-based music, which is based on understanding animal communication, will lead to more consistent and specific effects of music. Knowledge and appropriate use of animal-based music are important in future research and applications if we are to improve the well-being of animals that are dependent upon human care for their survival.

Autonomic factors do not underlie the elevated self-disgust levels in Parkinson's disease.

IntroductionParkinson’s disease (PD) is manifested along with non-motor symptoms such as impairments in basic emotion regulation, recognition and expression. Yet, self-conscious emotion (SCEs) such as self-disgust, guilt and shame are under-investigated. Our previous research indicated that Parkinson patients have elevated levels of self-reported and induced self-disgust. However, the cause of that elevation–whether lower level biophysiological factors, or higher level cognitive factors, is unknown.MethodsTo explore the former, we analysed Skin Conductance Response (SCR, measuring sympathetic activity) amplitude and high frequency Heart Rate Variability (HRV, measuring parasympathetic activity) across two emotion induction paradigms, one involving narrations of personal experiences of self-disgust, shame and guilt, and one targeting self-disgust selectively via images of the self. Both paradigms had a neutral condition.ResultsPhoto paradigm elicited significant changes in physiological responses in patients relative to controls—higher percentages of HRV in the high frequency range but lower SCR amplitudes, with patients to present lower responses compared to controls. In the narration paradigm, only guilt condition elicited significant SCR differences between groups.ConclusionsConsequently, lower level biophysiological factors are unlikely to cause elevated self-disgust levels in Parkinson’s disease, which by implication suggests that higher level cognitive factors may be responsible.

Emotional Distraction by Constant Finger Tapping

Abstract. This study examined the effects of emotional distraction in the context of recalling stressful interpersonal events in daily life. Previous studies have revealed that distraction decreases unpleasant emotions. In this study, we examined whether distraction tasks decrease unpleasant task-related thoughts in addition to unpleasant emotions. Furthermore, to investigate the implicit effects of emotional changes, we examined changes in pupil size in relation to unpleasant emotions and task-unrelated thoughts (TUT). The behavioral tasks were administered to 21 university students ( Mage = 21.24 ± 2.93 years; range: 18–30 years). After excluding participants for poor data quality, 16 (21.31 ± 3.34 years; 18–30 years) were included for further pupil data analysis. As an emotion induction procedure, participants were asked to freely recall memories of stressful interpersonal events in their daily lives and were given a series of questions about their recalled memories, which were presented on the monitor. In the following distraction experiment, questions during the emotion induction procedure were represented as emotional stimulation; a distraction task (non-constant or constant finger tapping) or rest condition was then performed; subsequently, ratings were given for attentional state, thought types conceived during the tasks, and emotional state. Upon analysis, differences in the ratings for unpleasant emotion and TUT were non-significant between all conditions. Nevertheless, pupil dilation in the non-constant and constant conditions was associated with decreased unpleasant emotions ( p < .05; p < .05 to .01). More importantly, pupil dilation was associated with decreased unpleasant TUT ( p < .05) only in the constant condition. Although the observed effects were subtle, we found that constant finger tapping decreased unpleasant emotions and TUT. It is expected for a future emotion regulation study to further investigate the effects in the relationships among emotions, thoughts, and physiological states, which can help in coping with unpleasant emotions.

The Effects of Emotional Design on Multimedia Learning and Appreciation of Chinese Poetry

Painting, music, literature, and other art forms embody the essence of human wisdom and induce esthetic experience, among which poetry is inherently creative, because it contains a wealth of symbols, imageries, insights, and so forth. The appreciation and learning of Chinese poetry is an important part of the curriculum in secondary schools. However, studies have mainly focused on textual characters of poetry, with little literature focusing on esthetic appreciation and in-depth learning of poetry. In this vein, we ask whether emotional designs will promote the appreciation and learning of Chinese poetry. To answer this question, we explored the influence of the combination of external emotion induction (positive and neutral movie clips) and internal colorful design (chromatic and achromatic) on esthetic preference and learning of poetry. One hundred and sixty-six participants (14–15 years old) were randomly assigned to one of four conditions created by two factors (external emotion induction and internal colorful design). The results showed that the combination of external emotion induction and internal colorful design promoted positive emotions, retention, and transfer performances of learners. Furthermore, perceived difficulty of learners decreased significantly when external emotional induction and internal colorful design were both positive. Consequently, these findings indicated that emotional designs in multimedia facilitated the learning performance of middle school students in Chinese poetry, and supported the cognitive-affective theory of learning with media. This research was a preliminary exploration of emotional design in humanities.

The Impact of Homeostatic and Circadian Sleep Processes on Non-Suicidal Self-Injury and Suicide Urges in Borderline Personality Disorder

Objective Borderline personality disorder (BPD) involves high rates of non-suicidal self-injury (NSSI) and suicidal behaviors, which are often preceded by urges. Disrupted sleep processes have been linked to NSSI and suicidal behaviors. However, it is unclear which specific sleep processes influence NSSI and suicide urges at rest (i.e., baseline) or in response to distress (i.e., reactivity) in BPD, and thus require targeting in BPD-specific interventions. This study examined whether two distinct homeostatic sleep processes (i.e., total sleep time [TST] and time in bed [TIB]), and one circadian sleep process (i.e., chronotype, or tendencies toward early versus late bed and rise times) predict baseline NSSI and suicide urges and urge reactivity in BPD. Methods Forty adults with BPD completed a seven-day sleep diary to measure average TST and TIB. They then completed a questionnaire to measure chronotype and underwent an experiment wherein they rated NSSI and suicide urges at baseline and following an emotion induction. Results Generalized estimating equations revealed that higher TST was associated with lower baseline NSSI urges, and lower suicide urge reactivity. Additionally, higher TIB predicted higher NSSI urge reactivity. Conclusions Sleep deprivation and extended time in bed may increase proclivity toward NSSI and/or suicide. Targeting these variables in BPD interventions may ultimately facilitate the reduction of NSSI and suicidal acts. Highlights Higher total sleep time predicts lower baseline NSSI urges, suicide urge reactivity Higher time in bed predicts higher NSSI urge reactivity Reducing sleep deprivation in BPD may facilitate reductions in suicide, NSSI urges

Deontological Guilt and Disgust Sensitivity Modulate Moral Behaviour.

ObjectiveDeontological Guilt (DG), and Altruistic Guilt (AG) emerge from the appraisal of violating an internalized rule or an altruistic principle, respectively. DG is strictly connected with Disgust Sensitivity and plays a key role in the development and maintenance of Obsessive-Compulsive Disorder (OCD). Previous studies investigated how DG affects responses to hypothetical moral dilemmas, however how DG and Disgust Sensitivity interact modulating moral behavior is still unknown.MethodsSTUDY 1. 46 healthy participants performed an ecological paradigm in which people can spontaneously decide to lie to obtain a reward (egoistic lie) or give it away (altruistic lie) after three emotional inductions: DG, AG or neutral. Furthermore, OCD traits, Morality, Guilt Propensity and Disgust Sensitivity were assessed by means of questionnaires. STUDY 2. 27 participants from the original sample were retested during the COVID-19 lockdown in Italy to ascertain whether the pandemic modified traits related to morality, disgust, guilt or OCD symptoms and whether these changes modulated moral behavior (measured by a task in which cheating was associated to higher pay-offs).ResultsSTUDY 1. Compared to the neutral, after the DG induction participants produced less altruistic and more egoistic lies. This effect was stronger in participants with high Disgust Sensitivity. STUDY 2. During the COVID-19 lockdown participants became more sensitive to the Authority pillar of the Moral Foundations and more sensitive to Disgust: this increment in deontological morality affected (im) moral behavior depending on changes in Disgust Sensitivity.ConclusionsOur data suggest that people with high Disgust Sensitivity are more affected by deontological inductions which translate to higher immorality, supposedly by lowering their moral self-image. These results might have important clinical implications as they suggest that addressing Disgust Sensitivity in therapy, might also decrease the effect of guilt on patients’ behavior.

Augmented Reality Textbook: A Classroom Quasi-Experimental Study

Augmented Reality (AR) has evolved considerably over the last ten years, having been implemented in several areas, including education. Multiple AR systems have been developed and tested in the laboratory dissociated from the reality of the classroom and without considering the pedagogical material used by students and teachers. We developed an AR prototype based on a natural sciences sixth-grade textbook. This prototype allows the use of the traditional textbook without changes, admitting the creation of new layers of virtual information. We describe the comparative analysis of using the augmented textbook versus the textbook without AR. This research was developed with a quasi-experimental study with 50 students in an elementary school. The results show that the AR textbook prototype can have a positive impact on the perception of understanding, the perception of innovation, satisfaction, emotional induction, and student learning. These results, also allow us to generate guidelines that could help to design future augmented textbooks.

Tax compliance is not fundamentally influenced by incidental emotions: An experiment

The present study investigates the impact of incidental emotions on tax compliance behavior in an experimental setting. Different theories are divided about how experiencing incidental emotions should influence tax decisions and the few existing studies yield inconsistent results. Our aim was to investigate differences between three specific emotions, namely anger, fear, and happiness. This allowed a comparison in compliance behavior as a function of differences in emotional valence as well as in specific emotional qualities. For this purpose, a sample of 264 individuals participated in a tax experiment. After a baseline treatment, one of the three emotions was induced using video-clips with background music. Moreover, emotional arousal was assessed by measuring electrodermal activity. Manipulation check items as well as elevated arousal levels after the emotion induction provided support for a successful emotion induction. Nevertheless, we did not observe any tax compliance differences between the anger, fear, and happiness conditions. Our results speak against a fundamental role of incidental emotions for tax compliance decisions.

Effect of mental resilience of left-behind children on self-esteem and emotional processing bias and social coping styles.

The long-term separation of parents and children as well as the incomplete family structure affect the mental health development of left-behind children and the formation of healthy personality, good interpersonal relationships and positive coping styles in adulthood. At present, there is insufficient empirical investigations on the mental resilience of left-behind children. It is aimed to understand the mental health of left-behind children and explore the characteristics of mental resilience, self-esteem and emotional processing bias, as well as social coping styles. The random sampling method is used to select the left-behind children as the research subject. The general demographic information questionnaire, RSCA (Resilience Scale for Chinese Adolescent), emotional self-rating scale, SES (Self-Esteem Scale), and coping style questionnaire are used for the survey. Also, the experiments on cognitive processing bias effects of self-esteem and emotion are further carried out. There are differences in demographic variables in mental resilience, self-esteem level, emotional level, and social coping styles. The low mental resilience group shows a processing bias towards low praise words, while the high mental resilience group shows a processing bias towards high praise words. At a low level of self-esteem, there is an interaction between mental resilience and self-esteem on low praise words. Mental resilience has a significant effect on the cognitive processing bias of emotion. Under the induction of positive emotions, the high mental resilience group responds significantly more slowly to the negative words than the low mental resilience group. Under the induction of negative emotions, the high mental resilience group responds significantly faster to the negative words than the low mental resilience group. Promoting the mental health education of left-behind children can start from enhancing positive emotions, reducing negative emotions, developing high self-esteem, and improving mature coping styles.

Emotion induction in young and old persons on watching movie segments: Facial expressions reflect subjective ratings.

Film clips are established to induce or intensify mood states in young persons. Fewer studies address induction of mood states in old persons. Analysis of facial expression provides an opportunity to substantiate subjective mood states with a psychophysiological variable. We investigated healthy young (YA; n = 29; age 24.4 ± 2.3) and old (OA; n = 28; age 69.2 ± 7.4) participants. Subjects were exposed to film segments validated in young adults to induce four basic emotions (anger, disgust, happiness, sadness). We analyzed subjective mood states with a 7-step Likert scale and facial expressions with an automated system for analysis of facial expressions (FaceReader™ 7.0, Noldus Information Technology b.v.) for both the four target emotions as well as concomitant emotions. Mood expressivity was analysed with the Berkeley Expressivity Questionnaire (BEQ) and the Short Suggestibility Scale (SSS). Subjective mood intensified in all target emotions in the whole group and both YA and OA subgroups. Facial expressions of mood intensified in the whole group for all target emotions except sadness. Induction of happiness was associated with a decrease of sadness in both subjective and objective assessment. Induction of sadness was observed with subjective assessment and accompanied by a decrease of happiness in both subjective and objective assessment. Regression analysis demonstrated pre-exposure facial expressions and personality factors (BEQ, SSS) to be associated with the intensity of facial expression on mood induction. We conclude that mood induction is successful regardless of age. Analysis of facial expressions complement self-assessment of mood and may serve as a means of objectification of mood change. The concordance between self-assessment of mood change and facial expression is modulated by personality factors.

Remotely Perceived: Investigating the Influence of Valence on Self-Perception and Social Experience for Dyadic Video-Conferencing With Personalized Avatars

Avatar use on video-conference platforms has found dual purpose in recent times as a potential method for ensuring privacy and improving subjective engagement with remote meeting, provided one can also ensure a minimal loss in the quality of social interaction and sense of personal presence. This work focuses on interactions of this sort through real-time motion captured 3D personalized virtual avatars in a 2D video-conferencing context. Our experiments were designed with the intention of exploring previously defined perceptual illusions that occur with avatar-use in Virtual and Augmented Reality settings, outside of the immersive technological domains where they are normally measured. The research described here was aimed at empirically evaluating three separate dimensions of human-avatar interaction. The first was humans-as-avatars, with experimental conditions that were designed to measure changes to subjective perceptions of self-face ownership and self-concept. The second focus was other-perception, with the unique design of the studies outlined below among the first to measure social presence in a video-call between two human-driven avatars. The third emphasis was on the experiential content involved in avatar use, as there were measurements for emotion induction, fatigue and behavior change included in the data collection. The results describe some evidence for face and body ownership, while participants also reported high levels of social presence with the other avatar, indicating that avatar cameras could be a favorable alternative to non-camera feeds in video conferencing. There were also some useful insights gained regarding emotion elicitation in non-video vs. avatar conditions, as well as avatar-induced behavior change.

Effects of two different emotion-inducing methods on the emotional memory of non-clinically depressed individuals.

In the study of emotional memory bias in depressed individuals, most previous studies have used emotional materials, but there were significant differences in the effects of different emotion-inducing methods on face memory. In the present study, two experiments were conducted to explore the effects of different emotion-inducing methods on memory between healthy participants and non-clinically depressed participants. The results from experiment 1 showed that when feedback was used as induction, the memory performance of the non-clinical depression group was significantly higher than that of the healthy group under the condition of negative feedback. Under positive and neutral feedback, there were no significant differences between the two groups. In experiment 2, when emotional materials were used as a mode of induction, no significantly difference in each emotional condition between the healthy and depressed groups was found. The results of the present study show that different methods of emotional induction have different effects on depressed participants. Compared with the emotion induced by the emotional material, the non-clinical depressed participants had a better memory effect induced by negative emotional events.
