Positive Autobiographical Memories Research Articles

Life narratives in the context of war trauma

The article is devoted to the analysis of life narratives in the context of war trauma. One of the most important tasks of social cognition is to predict the intentions of others towards us and people we care about, this information is best conveyed by a person's moral character, not sociability, and it is also important to predict the probability that a person will do what he is going to do, especially as it relates to the trauma of war and suicidal intentions common in our time. However, we assume that sociability and memories of the self before the war or before the traumatic event determine how effectively a person uses his skills to support his moral or immoral intentions, in fact this information is important from the point of view of adaptation. The purpose of the research is to study the peculiarities of life narratives, in particular those determined by morality, positive or negative attitude towards oneself in the context of war trauma. The objectives of the study are to define the concept of moral trauma, its connection with positive or negative self-attitude, PTSD, autobiographical memories of the events preceding the trauma, including the war in general. Research results: A positive attitude towards morality promotes the emergence of such phenomena as mutual altruism, encouraging cooperation for the common good. A negative attitude toward immorality promotes phenomena such as punishment, discouraging destructive behavior such as cheating, stealing, and free-riding. Therefore, it is critical to determine whether the influence of moral traits on liking and positive attitudes toward self and others is dominant and how it is related to positive autobiographical memories and life narratives, particularly in wartime, when immoral and moral actions are often closely related. and moral trauma has become a common phenomenon not only for the military, but also for civilians in Ukraine.

Posttraumatic stress symptoms and positive autobiographical memory characteristics in everyday life.

Individuals with posttraumatic stress symptoms (PTSS) report difficulties engaging with positive autobiographical memories. Extending this line of research, we examined daily-level concurrent and lagged associations between PTSS severity and positive memory characteristics (vividness, coherence, accessibility, time perspective, sensory details, visual perspective, emotional intensity, sharing, distancing, and valence). The sample included 88 trauma survivors (Mage = 39.89 years, 59.1% female) who completed seven daily measures of PTSS and positive memory characteristics. Multilevel models examined concurrent and lagged associations between PTSS severity and positive memory characteristics. The results indicated that days with higher PTSS severity were associated with less accessibility, β = -.21, p <.001; less visual perspective, β = -0.13, p =.034; and lower positive valence of the memory, β = -.19, p =.003, as well as more emotional intensity associated with, β =.13, p =.041, and more distancing from, β =.21, p <.001, the memory. Supplemental lagged analyses indicated that higher previous-day PTSS severity was associated with more next-day distancing from, β =.15, p =.042, and sensory details of, β =.17, p =.016, the memory. Findings suggest that individuals with more severe PTSS have difficulties accessing positively valenced memories from a first-person perspective, are more distant from the recalled positive memory, and report more emotional intensity when retrieving the memory. Thus, improving access to and reducing distance from positive autobiographical memories, as well as addressing emotional intensity surrounding the retrieval of these memories, may be potential clinical targets for PTSS interventions.

Do childhood experiences influence associations between posttraumatic stress disorder symptoms and positive autobiographical memories among military veteran students? An exploratory study

ABSTRACT Background Evidence links posttraumatic stress disorder (PTSD) symptoms and features of positive autobiographical memories (accessibility, vividness, coherence, sharing, emotional intensity, distancing). There is a knowledge gap on how adverse childhood experiences (ACEs) and benevolent childhood experiences (BCEs) may influence these relationships. Objectives The current study explored whether the number ACEs or BCEs moderated associations between PTSD symptom severity and features of positive autobiographical memories. Design and Methods The sample included 124 student military veterans who had experienced a trauma (M age = 33.90; 77.4% male; 75.0% White). Results Path analyses showed more PTSD symptom severity was significantly associated with less positive autobiographical memory vividness (β = −0.26, p = .019, R2 = 0.06). Further, the number of ACEs moderated the relationship between PTSD symptom severity and positive autobiographical memory accessibility (β = −0.25, p = .023, R2 = 0.10) and vividness (β = −0.20, p = .024, R2 = 0.10). Among individuals with more ACEs (1 SD above the mean) compared to those with fewer ACEs (1 SD below the mean), less accessibility and vividness of positive autobiographical memories was associated with greater PTSD symptom severity. The number of BCEs was not a significant moderator. Conclusions Positive memory-based interventions may be particularly useful to address PTSD symptoms among military veterans with a history of childhood adversity.

Positive autobiographical memory recall does not influence temporal discounting: An internal meta-analysis of experimental studies

People tend to discount the value of future rewards as the delay to receiving them increases. This phenomenon, known as temporal discounting, may underlie many impulsive behaviors, such as drug abuse and overeating. Given the potential role of temporal discounting in maladaptive behaviors, many efforts have been made to find experimental manipulations that reduce temporal discounting. One class of manipulations that has held some promise involves recalling positive autobiographical memories prior to making intertemporal choices. Just as imagining positive future events has been shown to reduce temporal discounting, a few studies have shown that recalling positive past events reduces temporal discounting, especially if memory retrieval evokes positive affective states, such as gratitude and nostalgia. However, we failed to replicate these findings. Here we present an internal meta-analysis combining data from 14 studies (n = 758) that involved within-subjects positive memory recall-based manipulations. In each study, temporal discounting was assessed using a monetary intertemporal choice task. The average effect size was not significantly different from zero. This finding helps elucidate the neurocognitive mechanisms of temporal discounting; whereas engaging the episodic memory system to imagine future events might promote more patience, engaging the episodic memory system to imagine past events does not.

Guided recall of positive autobiographical memories increases anticipated pleasure and psychological resources, and reduces depressive symptoms: a replication and extension of a randomised controlled trial of brief positive cognitive-reminiscence therapy

ABSTRACT Reminiscence-based interventions focus on recalling autobiographical memories and reflective reasoning to develop a healthy and adaptive view of oneself and one’s life. This study aimed to replicate the effects of a three-session, group-based, positive-memory version of cognitive-reminiscence therapy (CRT) on psychological resources and mental well-being and extend the findings to anticipated pleasure. The participants (N = 75, M age = 43.7 (SD = 16.7), 60% females) were randomised to CRT or control group. Anticipated pleasure, psychological resources (schemas of positive self-esteem, self-efficacy, meaning in life, optimism), mental well-being (depression, anxiety, and stress symptoms) and theorised change processes (automatic negative thoughts, awareness of narrative identity) were assessed. Relative to the control group, the CRT group reported significantly higher anticipated pleasure (d = 0.76–0.93) and psychological resources of self-esteem, self-efficacy, and optimism (d’s = 0.58–0.99) at post-CRT and follow-up, and lower depressive symptoms post-CRT and at follow-up (d = 0.56–0.67). Findings on meaning in life and negative automatic thinking were partially replicated. This study replicates findings of the effectiveness of this intervention for improving psychological resources such as self-worth, confidence and optimism and depressive symptoms, and indicates additional effects on anticipated pleasure. CRT may serve as a standalone intervention, or as an adjunct “memory booster” for interventions focused on future thinking and related anticipated reward.

The retrieval of neutral and positive autobiographical memories: a pilot study

The retrieval of neutral and positive autobiographical memories: a pilot study

Recalling and anticipating positive events to improve the positive affect and mental health of adolescents: A cluster randomized controlled trial in secondary schools

This cluster randomized controlled trial examined the effectiveness of Positive Events Training (PET), a combined group training aimed at simultaneously improving positive autobiographical memory (AM) and episodic future thinking (EFT) among adolescents (12–16 years). Delivered as a universal school-based program, PET was compared with an active (creative writing) control group (CREAT). Effects on resilience, wellbeing, positive emotions, emotional response styles towards positive emotions (savoring, dampening), anhedonia, depressive symptoms, and multiple AM and EFT indices were examined. Adolescents (NPET = 95, NCREAT = 93) completed self-report scales at baseline, post-training and two-month follow-up. Multilevel models revealed that PET led to significant improvements in certain AM and EFT skills. Moreover, a decrease in anhedonia was observed at post-training. However, this effect did not withstand correction for multiple testing. Absence of changes in the other outcomes should be interpreted within the context of the universal school-based approach and the potential limited scope for detectable changes. Exploratory analyses suggest the importance of further investigating PET's potential in addressing positive affect dysregulations in indicated samples, and exploring perceived likelihood of generated future events and dampening as potential underlying mechanisms. Study limitations and future directions to maximize the demonstrated potential of PET are discussed.

The Functional Neuroimaging of Autobiographical Memory for Happy Events: A Coordinate-Based Meta-Analysis.

Neuroimaging studies using autobiographical recall methods investigated the neural correlates of happy autobiographical memories (AMs). The scope of the present activation likelihood estimation (ALE) meta-analysis was to quantitatively analyze neuroimaging studies of happy AMs conducted with autobiographical recall paradigms. A total of 17 studies (12 fMRI; 5 PET) on healthy individuals were included in this meta-analysis. During recall of happy life events, consistent activation foci were found in the frontal gyrus, the cingulate cortex, the basal ganglia, the parahippocampus/hippocampus, the hypothalamus, and the thalamus. The result of this quantitative coordinate-based ALE meta-analysis provides an objective view of brain responses associated with AM recollection of happy events, thus identifying brain areas consistently activated across studies. This extended brain network included frontal and limbic regions involved in remembering emotionally relevant positive events. The frontal gyrus and the cingulate cortex may be responsible for cognitive appraisal processes during recollection of happy AMs, while the subthalamic nucleus and globus pallidus may be involved in pleasure reactions associated with recollection of happy life events. These findings shed light on the neural network involved in recalling positive AMs in healthy individuals, opening further avenues for future research in clinical populations with mood disorders.

How remembering positive and negative events affects intimacy in romantic relationships

Previous studies provide some evidence that recalling positive autobiographical memories can foster feelings of intimacy in social relationships. The present research aimed to extend this finding by examining the effects of negative relationship memories on current feelings of intimacy. In Study 1, 71 adults recalled either two positive or two negative events experienced with their partner. Intimacy (feelings of warmth, relationship closeness) was measured before and after remembering. Relationship closeness increased after recalling positive relationship memories, whereas feelings of warmth were reduced after the recall of negative relationship memories. In Study 2, 187 adults recalled two relationship conflicts and rated intimacy toward their partner (feelings of warmth, relationship closeness) before and after remembering. Replicating the findings of Study 1, we found feelings of warmth to be reduced after the recall of relationship conflicts. Relationship closeness was likely to decrease the more conflicts were considered personally significant and the more a person had used self-distraction to regulate their emotions during the conflict. Future research may identify personal characteristics that could explain why, for some people, the recall of negative relationship memories is hurtful, whereas it brings others closer to their partner.

Daily-level associations between posttraumatic stress disorder symptoms and reactions to retrieving positive autobiographical memories

Trauma survivors with posttraumatic stress disorder (PTSD) report difficulties accessing and describing positive memories. To understand these patterns, we examined daily-level relations of PTSD symptoms with affective, cognitive (dwelling/rumination; pushing memory out of one’s mind; suppression; avoidance; distraction; thinking about something else; remembering negative or positive memories/events; negative or positive thoughts; accepting or disapproving memory; reinterpreting memory), and behavioral (using alcohol/drugs; smoking cigarettes; cravings for or seeking out cigarettes/alcohol/drugs; craving, seeking out, or consuming large amounts of food; dissociation; engaging in risky behaviors; sharing memories; interference with ongoing task; arousal) reactions to retrieving positive memories. Eighty-eight trauma survivors (Mage= 39.89 years; 59.1% female) completed 7 daily measures of PTSD and reactions to retrieving positive memories. Days with more PTSD severity were associated with higher odds of same-day suppression, avoidance, distraction, thinking about something else, smoking cigarettes, craving substances, craving, seeking out, or consuming large amounts of food, dissociation, remembering negative memories/events/thoughts, engaging in risky behaviors, interference with ongoing tasks, and arousal (ORs=1.10–1.22); and greater negative affect (β = 0.27). Supplemental lagged analyses indicated some associations between previous-day reactions to positive memory retrieval and next-day PTSD severity and vice versa. Trauma survivors with PTSD symptoms report negative and avoidance-oriented reactions to retrieving positive memories.

The Effects of the Processing of Positive Memories Technique on Posttrauma Affect and Cognitions Among Survivors of Trauma: Protocol for a Daily Diary Study.

The Processing of Positive Memories Technique (PPMT) is a promising new treatment approach for posttraumatic stress disorder (PTSD), which involves detailed narration and processing of specific positive autobiographical memories. Indeed, preliminary case-series studies have found reductions in PTSD symptoms, negative affect, and negative cognitions among survivors of trauma who have received PPMT. However, PPMT's effects have not been investigated at the daily level. In this study, we describe the protocol for a study that will examine the daily-level impacts of PPMT in a trauma-exposed, nonclinical community sample. This study uses an innovative research protocol that combines case-series design and daily diary approaches to examine changes in daily affect, daily cognitions, and daily PTSD symptoms pre- and post-PPMT. We hypothesize that at the daily level, in comparison to their own pre-PPMT levels, following the PPMT intervention, participants will report (1) a lower count of endorsed daily PTSD symptoms, (2) increases in daily positive affect and decreases in daily negative affect, (3) increases in positive affect reactivity to daily positive events, and (4) decreases in daily posttrauma cognitions. We are currently recruiting participants (target n=70) from a metroplex in the southwest United States. Following a screening survey, eligible participants complete a preintervention baseline survey, followed by 21 daily surveys in their natural environments. Then, they receive 4 PPMT sessions on a weekly basis. After the conclusion of the PPMT intervention, participants complete a postintervention outcome survey and 21 daily surveys. To compare daily affect, daily cognitions, and daily PTSD symptoms before and after PPMT, we will use the daily diary report data and conduct multilevel random intercepts and slopes linear regression models. Data collection was initiated in March 2022 and is expected to end by June 2024. As of November 28, 2023, a total of 515 participants had consented to the study in the screening phase. No analyses will be conducted until data collection has been completed. Study findings could clarify whether deficits in positive autobiographical memory processes may also characterize PTSD alongside deficits in traumatic memory processes. Furthermore, PPMT could be an additional therapeutic tool for clinicians to help clients reduce posttraumatic distress in their everyday lives. DERR1-10.2196/51838.

Hooking the Self Onto the Past: How Positive Autobiographical Memory Retrieval Benefits People With Social Anxiety

Do people with social anxiety (SA) benefit from positive memory retrieval that heightens self-relevant meaning? In this preregistered study, an analog sample of 255 participants with self-reported clinically significant symptoms of SA were randomly assigned to retrieve and process a positive social-autobiographical memory by focusing on either its self-relevant meaning (deep processing) or its perceptual features (superficial processing). Participants were then socially excluded and instructed to reimagine their positive memory. Analyses revealed that participants assigned to the deep processing condition experienced significantly greater improvements than participants in the superficial processing condition in positive affect, social safeness, and positive beliefs about others during initial memory retrieval and in negative and positive beliefs about the self following memory reactivation during recovery from exclusion. These novel findings highlight the potential utility of memory-based interventions for SA that work by “hooking” self-meaning onto recollections of positive interpersonal experiences that elicit feelings of social acceptance.

Neurofeedback and Affect Regulation Circuitry in Depressed and Healthy Adolescents.

Neurodevelopmental psychopathology seeks to understand higher-order emotion regulation circuitry to develop new therapies for adolescents with depression. Depressed (N = 34) and healthy youth (N = 19) completed neurofeedback (NF) training and exhibited increased bilateral amygdala and hippocampus activity in the region of interest (ROI) analyses by recalling positive autobiographical memories. We tested factors supportive of the engagement of emotion regulation's neural areas during NF (i.e., parental support, medication, and gender effects upon anterior cingulate cortex (ACC) engagement). Whole-brain analyses yielded effects of NF vs. control condition and effects of diagnosis. Youth showed higher amygdala and hippocampus (AMYHIPPO) activity during the NF vs. control condition, particularly in the left hippocampus. ACC's activity was also higher during NF vs. control. Higher average ACC activity was linked to better parental support, absent depression, female gender, and absent medication. Control youth showed higher average AMYHIPPO and ACC activity throughout the task and a faster decline in activity vs. depressed youths. Whole-brain level analyses showed higher activity in the frontotemporal network during the NF vs. control conditions, suggesting targeting their connectivity in future neurofeedback trials.

Aberrant neural network activation during reliving of autobiographical memories in adolescent depression

BackgroundAdolescents with depression exhibit negative biases in autobiographical memory with detrimental consequences for their self-concept and well-being. Investigating how adolescents relive positive autobiographical memories and activate the underlying neural networks could reveal mechanisms that drive such biases. This study investigated neural networks when reliving positive and neutral memories, and how neural activity is modulated by valence and vividness in adolescents with and without depression. MethodsAdolescents (N = 69; n = 17 with depression) retrieved positive and neutral autobiographical memories. On a separate day, they relived these memories during fMRI scanning, and reported on pleasantness and vividness after reliving each memory. We used a multivariate, data-driven approach – event-related independent component analysis (eICA) – to characterize neural networks supporting autobiographical recollection. ResultsAdolescents with depression reported their positive memories as significantly less pleasant compared to healthy controls, while subjective vividness was unaffected. Using eICA, we identified a broad autobiographical memory network, and subnetworks related to reliving positive vs neutral memories. These subnetworks comprised a ‘self-referential processing network’ including medial prefrontal cortex, posterior cingulate cortex/precuneus, and temporoparietal junction, anti-correlating with parts of the central executive network and salience network. Adolescents with depression exhibited aberrant activation in this self-referential network, but only when reliving relatively ‘low’ pleasant memories. ConclusionsOur findings provide first insights into how the quality of reliving autobiographical memories in adolescents with depression may relate to aberrant self-referential neural network activation, and underscore the potential of targeting memory reliving in therapeutic interventions to foster self-esteem and diminish depressive symptoms.

Neural modulation enhancement using connectivity-based EEG neurofeedback with simultaneous fMRI for emotion regulation

Emotion regulation plays a key role in human behavior and overall well-being. Neurofeedback is a non-invasive self-brain training technique used for emotion regulation to enhance brain function and treatment of mental disorders through behavioral changes. Previous neurofeedback research often focused on using activity from a single brain region as measured by fMRI or power from one or two EEG electrodes. In a new study, we employed connectivity-based EEG neurofeedback through recalling positive autobiographical memories and simultaneous fMRI to upregulate positive emotion. In our novel approach, the feedback was determined by the coherence of EEG electrodes rather than the power of one or two electrodes. We compared the efficiency of this connectivity-based neurofeedback to traditional activity-based neurofeedback through multiple experiments. The results showed that connectivity-based neurofeedback effectively improved BOLD signal change and connectivity in key emotion regulation regions such as the amygdala, thalamus, and insula, and increased EEG frontal asymmetry, which is a biomarker for emotion regulation and treatment of mental disorders such as PTSD, anxiety, and depression and coherence among EEG channels. The psychometric evaluations conducted both before and after the neurofeedback experiments revealed that participants demonstrated improvements in enhancing positive emotions and reducing negative emotions when utilizing connectivity-based neurofeedback, as compared to traditional activity-based and sham neurofeedback approaches. These findings suggest that connectivity-based neurofeedback may be a superior method for regulating emotions and could be a useful alternative therapy for mental disorders, providing individuals with greater control over their brain and mental functions.

Toward a computational understanding of how reminiscing about positive autobiographical memories influences decision-making under risk.

Recent computational psychiatric research has dissected decision-making under risk into different underlying cognitive computational constructs and identified disease-specific changes in these constructs. Studies are underway to investigate what kind of behavioral or psychological interventions can restore these cognitive, computational constructs. In our previous study, we showed that reminiscing about positive autobiographical memories reduced risk aversion and affected probability weighting in the opposite direction from that observed in psychiatric disorders. However, in that study, we compared positive versus neutral memory retrieval by using a within-subjects crossover posttest design. Therefore, the change of decision-making from baseline is unclear. Furthermore, we used a hypothetical decision-making task and did not include monetary incentives. We attempt to address these limitations and investigated how reminiscing about positive autobiographical memories influences decision-making under risk using a between-subjects pretest posttest comparison design with performance-contingent monetary incentives. In thirty-eight healthy, young adults, we found that reminiscing about positive memories reinforced the commonly observed inverted S-shaped nonlinear probability weighting (f = 0.345, medium to large in effect size). In contrast, reminiscing about positive memories did not affect risk aversion in general. Given that the change in probability weighting after reminiscing about positive memories is in the opposite direction from that observed in psychiatric disorders, our results indicate that positive autobiographical memory retrieval might be a useful behavioral intervention strategy for amending the altered decision-making under risk in psychiatric diseases.

Reducing the stickiness of negative memory retrieval through positive memory training in adolescents

Background and objectivesIndividuals at risk for depression exhibit a decreased ability to disengage from negative memory retrieval during times of mental distress, partly because they have difficulty retrieving positive memories to repair sad mood. In this study, we tested whether this persistent tendency for negative memory retrieval could be reduced in adolescents through repeated practice to retrieve positive autobiographical memories, namely Positive Memory Specificity Training (PMST). Further, we examined the impact of this intervention on secondary outcomes, including depressive symptoms, emotion regulation strategies, and fear of positive emotions. MethodsAdolescents (n = 68) between 16 and 18 years old were randomly allocated to either PMST or bogus control training. Persistent negative memory retrieval was assessed following the training using a behavioral decision-making task (Emotional Reversal Learning Task). Additionally, participants completed self-report measurements (e.g., depressive symptoms) before and two weeks after the training. ResultsWe found preliminary supportive evidence for a significant training effect such that adolescents following PMST showed less persistence in negative memory retrieval compared to those in the control group. Only for anhedonia a significant training effect was found, indicating a possible adverse effect of the intervention. LimitationsThe primary outcome was assessed only at post-intervention to prevent a potential learning effect due to repeated measurements. We cannot exclude the possibility that baseline individual differences contaminated our results. To examine possible adverse effects of PMST, larger sample are needed. ConclusionsPMST may help to reduce persistent negative memory retrieval in adolescents. Recommendations for future studies are addressed.

Effect of the emotional valence of autobiographical memory and parental bonding on depressive symptoms in a community sample

Retrospective perceptions of parental bonding may be a protective factor for emotional health. These perceptions are grounded in autobiographical memory, which plays a key role in the onset and maintenance of depressive symptomatology. The aim of the present study was to explore whether the emotional valence of autobiographical memories (positive and negative) and the dimensions of parental bonding (care and protection) have an impact on depressive symptomatology, examining the role of depressive rumination and possible age-related differences. A total of 139 young adults (18–28 years) and 124 older adults (65–88 years) completed the Parental Bonding Instrument, the Beck Depression Inventory (BDI-II), the Autobiographical Memory Test and the Short Depressive Rumination Scale. Our results show that positive autobiographical memories serve as a protective factor for depressive symptoms in both young and older adults. Additionally, in young adults, high paternal care and protection scores are associated with increased negative autobiographical memories, although this association has no effect on depressive symptomatology. In older adults, high maternal protection scores are directly related to greater depressive symptomatology. Depressive rumination significantly increases depressive symptoms in both young and older adults, with an increase in negative autobiographical memories in young adults, and a decrease in such memories in older adults. Our findings progress the understanding of the relationships between parental bonding and autobiographical memory with respect to emotional disorders, which, in turn, will help in the design of effective prevention measures.

The role of the personal relevance of images in retrieving autobiographical memories for emotion regulation: A randomized controlled trial study

Little is known about what types of positive specific autobiographical memory-inducing images are most effective in regulating emotions. This study analyses the effectiveness of personal relevance of images associated with specific positive autobiographical memories as a method of emotional regulation. The sample comprised 263 participants (179 women), divided into a group of young adults (N = 139) aged 18–28 years and a group of older persons (N = 124) aged 65 years and over. In a randomized controlled trial study, participants were randomly assigned to three experimental conditions based on the type of image used (images of International Affective Picture System (IAPS), images of places and personal photographs). Negative mood was induced by viewing a film clip. Positive mood induction was subsequently conducted through the presentation of six images (according to the group) associated with specific positive autobiographical memories. Changes in mood state were measured using the Positive and Negative Affect Schedule (PANAS) before and after each induction. SPSS 28.0 (IBM) statistical software was used for the data analysis. The positive mood induction procedure repaired participants’ mood state, increasing positive affect and decreasing negative affect. The older adults showed a greater increase in positive affect while their younger counterparts recorded a greater decrease in negative affect. The three types of images were equally effective in augmenting positive affect. Regarding the reduction in negative affect, the personal photographs scored highest in the group of young adults, while, in the older group, the IAPS images were the most effective. The findings of this study show that using images associated with positive specific autobiographical memories is an effective mood induction method. Consequently, the use of such images might be effective in interventions designed to enhance emotion regulation and reduce depressive symptomatology.

Investigating features that contribute to evaluations of intrusiveness for thoughts and memories

What makes a thought feel intrusive? One possibility is that traumatic experiences are the primary cause of intrusive thoughts and memories. Another possibility is that experiences of intrusiveness arise from the features involved with re-experiencing. We investigated several features that may lead a thought to feel intrusive: task-congruence, repetition, and affective content. In Experiment 1, participants listened to popular song clips expected to become stuck in one’s head. In Experiment 2, participants were cued to recall their own autobiographical memories. We found that both songs and autobiographical memories replaying mentally felt more intrusive when they were incongruent with the current task, cued repeatedly, and had negative emotional content. Additionally, even liked songs and positive autobiographical memories were evaluated as highly intrusive under some conditions. Based on these findings, we argue that intrusiveness is not limited to traumatic thoughts, but rather is a context-dependent evaluation influenced by a variety of features.
