The influence of induced dysphoria on autobiographical memory specificity and social problem solving: Examining the role of executive function.

Negative mood induction leads to reductions in autobiographical memory specificity (AMS) and social problem-solving (SPS). The aim was to establish if executive function contributes to changes in AMS and SPS following negative mood induction. Forty-four participants (study 1) completed the autobiographical memory test and measures of executive function (letter & category fluency) before and after a positive or negative mood induction (MI). Forty participants (study 2) completed the means-end problem solving task (MEPS) and (letter & category) fluency tasks before and after a positive or negative MI. In study 1, participants exhibited impaired AMS and fluency performance following a sad MI. Decrease in memory specificity pre-to post-MI was related to reductions in happy mood and letter fluency. In study 2, participants exhibited poorer performance on the MEPS and fluency tasks following a sad MI. Decreases in the number of relevant solutions generated on the MEPS pre-to post-MI was linked to increases in sad mood and decreases in letter fluency. In both studies, the influence of mood became non-significant once the effect of executive function was accounted for, which suggests that changes in AMS and SPS in response to induced mood were related to concomitant changes in executive function.

Thinking about the consequences: The detrimental role of future thinking on intrapersonal problem-solving in depression.

Despite the fact that depressed individuals encounter a multitude of social problems in daily life, research on social problem-solving has largely been dominated by research on interpersonal problems and there is a paucity of research on intrapersonal problems. Intrapersonal problems are linked to one's subjective psychological functioning and involve managing one's own feelings and emotions pertaining to the self. Given that depressed individuals exhibit impaired emotion regulation, it is possible that their ability to solve intrapersonal problems may be impaired, especially in relation to future thinking. The aim of this study was to investigate whether future thinking, in the form of thinking about the consequences of a problem being resolved or remaining unresolved has an impact on intrapersonal problem-solving in depression. Forty-five depressed and fifty-four non-depressed participants completed a modified version of the means end problem-solving task (MEPS). In the task, participants were presented with a series of intrapersonal problems and were asked to generate consequences of the problems being resolved or remaining unresolved. Participants were then presented with a positive resolution to each of the problems and were asked to solve the problem to achieve the positive resolution. Following a delay, participants were asked to recall all of the consequences initially generated. Overall, depressed individuals generated fewer-relevant means and less effective solutions to problems than non-depressed participants. Depressed individuals also demonstrated impaired intrapersonal problem-solving following the generation of resolved and unresolved consequences, compared to a baseline condition, where no consequences were generated. These findings suggest that future thinking impairs intrapersonal problem-solving and indicates that a more nuanced approach to future thinking and social problem-solving in depression is needed across different real-life problem-solving contexts.

Autobiographical memory specificity and restrained eating: examining the influence of priming with images of healthy and unhealthy foods.

BACKGROUND: Dietary restraint has been linked to deficits in the ability to recall detailed memories of personally experienced events (referred to as autobiographical memory specificity). As priming with healthy foods increases the salience of restraint it would be expected to lead to greater deficits in memory specificity. OBJECTIVE: To determine if priming word cues with images of healthy or unhealthy foods would influence the specificity of memory retrieval, and if deficits in memory specificity would be more evident in those reporting higher levels of dietary restraint, or currently dieting. METHODS: Sixty female undergraduates self-reported if they were currently dieting and completed measures of mood, restraint, and disinhibition, and a modified version of the autobiographical memory task. Participants were presented with positive and negative words (unrelated to eating concerns) and asked to retrieve a specific memory in response to each cue. A food image was shown prior to each word cue; half of the participants were primed with images of healthy foods and half with images of unhealthy foods. RESULTS: As expected, participants primed with healthy foods retrieved fewer specific memories than did those primed with unhealthy foods. However, neither restraint nor current dieting behaviour was associated with memory specificity. CONCLUSIONS: Differences in memory specificity between the priming conditions cannot be explained in terms of increased salience of restraint. However, it is plausible that unhealthy images led to an increase in positive affect, which in turn improved memory specificity. LEVEL OF EVIDENCE: Level I: Evidence obtained from: at least one properly designed experimental study.

Effects of Mindfulness Meditation Duration and Type on Well-being: an Online Dose-Ranging Randomized Controlled Trial.

Objectives: This multi-arm randomized controlled online trial explored the effects of two key mindfulness characteristics (dose and type) over 2 weeks on mental well-being, along with psychological distress and dispositional mindfulness, in a healthy community sample. Method: Participants were randomly assigned to one of four mindfulness interventions (~ 10 min or ~ 30 min of sitting or movement meditation) to practice daily for 2 weeks; 161 participants fully completed the study and were included in the final sample. We also explored self-reported adherence through how often participants practiced, along with dropout rate via how many participants fully completed the study. Results: Well-being and mindfulness scores increased-and distress scores decreased-within all four conditions. However, most importantly, there were no significant differences between the conditions as a function of meditation dose or type. There were also no differences between the conditions on how regularly the meditations were practiced irrespective of type or dose. Additionally, there was no difference on dropout rate regarding meditation dose. However, meditation type had an effect, with a significantly higher dropout rate for participants allocated to a movement meditation irrespective of the dose. Conclusions: Brief mindfulness meditation may offer some benefit to well-being regardless of the meditation type and dose but, fundamentally, no differences in effects were detected between short/long sitting meditations and short/long movement meditations. Moreover, the results indicate that movement meditations may possibly be harder to adhere to, potentially informing the tailoring of mindfulness-based self-help programs. Limitations and future directions are also discussed. Preregistration: This study was retrospectively registered with the Australian New Zealand Clinical Trials Registry (ACTRN12619000422123).

Increasing autobiographical memory specificity: Using kindness meditation to impact features of memory retrieval.

Individuals with a history of depression have an increased risk for future episodes. This risk has been linked with impaired features of autobiographical memory retrieval that remain when depressive symptoms abate, including memory specificity, remoteness, valence, and vantage perspective. Rumination has been shown to influence these impairments and can be reduced via compassion training. We therefore investigated the effects of a self-compassion meditation on autobiographical memory retrieval in remitted depression. Baseline data were collected (n = 50) using an extended version of the Autobiographical Memory Test where participants with remitted depression retrieved specific memories from a remote time period (10 cues) and from any time period (10 cues). Valence and vantage perspective were rated. Participants were then randomly allocated to a self-compassion meditation or (control) colouring intervention group. Baseline measures were reassessed after four weeks of the intervention. Results revealed increased retrieval of specific memories in the self-compassion group in comparison to the colouring group, and an increase in positive and field memories across groups while no remoteness changes were observed. This self-compassion meditation demonstrated initial promise as an intervention to influence features of autobiographical memory retrieval in remitted depression. Improvements were shown in specificity, valence, and vantage perspective. Addressing these features with this type of intervention might reduce a cognitive vulnerability to depression and should be investigated in future studies.

Sad reflections of happy times: depression vulnerability and experiences of sadness and happiness upon retrieval of positive autobiographical memories.

Instructed retrieval of positive autobiographical memories typically improves mood for healthy individuals, but not always for depressed individuals. No mood improvement may occur when depressed individuals retrieve positive memories that are self-incongruent, or when they ruminate upon positive memory retrieval. Mindfulness is associated with lower self-incongruency and rumination. The present study examined whether recurrent depression predicted emotional experience upon involuntary and voluntary retrieval of positive memories, and whether recurrent depression and trait mindfulness were associated with emotional experience upon positive memory retrieval through state rumination and self-incongruency. Recurrently and never-depressed individuals completed measures of depression, trait mindfulness, and a diary for reporting on everyday positive memories. Recurrently depressed individuals reported diminished happiness upon retrieving involuntary and voluntary positive memories compared to never-depressed individuals; and greater sadness upon involuntary positive memory retrieval, independent of current depression. Recurrent depression was associated with diminished happiness upon involuntary memory retrieval and greater sadness upon involuntary and voluntary positive memory retrieval, through state brooding, self-incongruency, or both. Higher trait mindfulness was associated with lower sadness upon involuntary and voluntary positive memory retrieval through state brooding and reflection. These findings highlight potential mechanisms in the relationship between depression vulnerability and emotional processing of positive autobiographical memories.

In the here and now: Future thinking and social problem-solving in depression.

This research investigates whether thinking about the consequences of a problem being resolved can improve social problem-solving in clinical depression. We also explore whether impaired social problem solving is related to inhibitory control. Thirty-six depressed and 43 non-depressed participants were presented with six social problems and were asked to generate consequences for the problems being resolved or remaining unresolved. Participants were then asked to solve the problems and recall all the consequences initially generated. Participants also completed the Emotional Stroop and Flanker tasks. We found that whilst depressed participants were impaired at social problem-solving after generating unresolved consequences, they were successful at generating solutions for problems for which they previously generated resolved consequences. Depressed participants were also impaired on the Stroop task, providing support for an impaired inhibitory control account of social problem-solving. These findings advance our understanding of the mechanisms underpinning social problem-solving in depression and may contribute to the development of new therapeutic interventions to improve social-problem solving in depression.

Using Visual Representations to Demonstrate Complexity in Mixed Emotional Development Across Childhood.

Previous studies have shown a developmental trend in mixed emotional understanding. As children develop throughout childhood, they begin to recognise simultaneity of positive and negative emotions. However, previous studies have limited ecological validity as they assessed emotion choice using only a single positive and single negative emotion. Therefore, the present study aims to broaden the understanding of mixed emotional development by allowing a wider emotion choice. Mixed emotions were measured using the analogue emotions scale (AES) which allows both intensity of the emotional responses and time to be captured. In the present study, 211 children aged 4-10 were divided into one of three protagonist conditions (self, peer and adult) and read a vignette about the protagonist moving house. Choosing from seven emotions (happy, calm, surprise, sad, worry, fear and anger), they plotted the intensity and duration of each emotion they thought was represented in the vignette. The present study replicated the developmental trend that younger children are more likely than older children to choose a single emotion, and older children are more likely to perceive more simultaneity of emotion than younger children. This trend was demonstrated in the number of emotions chosen, and also the complexity of the AES pattern plotted. Additionally, the present study extended previous research by demonstrating that by broadening the emotion choice, the emotion interaction is more complex than previous studies were able to show.

The shield of self-compassion: A buffer against disordered eating risk from physical appearance perfectionism.

General perfectionistic tendencies as well as perfectionism focussed specifically on one's physical appearance have been implicated as risk factors for disordered eating. This study extends previous research on protective factors by investigating self-compassion as a moderator of the relationship between both general and physical-appearance-perfectionism and disordered eating. A cross-sectional online survey assessed general perfectionism, physical-appearance-perfectionism, disordered eating symptoms, self-compassion and negative affect in female UK university students (N = 421). Results showed physical-appearance-perfectionism explained variance (15%) in disordered eating symptoms above general perfectionism and negative affect. Both perfectionistic concerns about and strivings for appearance perfection were significant unique predictors of disordered eating. Self-compassion moderated the relationship between both perfectionistic concerns and strivings of physical-appearance-perfectionism, but not general perfectionism, and disordered eating. This study suggests both perfectionistic concerns about and strivings for appearance perfection represent potential risk factors for disordered eating among female university students and that self-compassion may reduce their impact.

Mood Disorders in High-Functioning Autism: The Importance of Alexithymia and Emotional Regulation.

Individuals with autism spectrum disorder (ASD) often have co-morbid anxiety and depression. Alexithymia and emotion regulation difficulties are commonly seen in individuals with ASD and in mood disorders. We hypothesized that alexithymia and emotional regulation would mediate the relationship between autistic features and anxiety/depression symptom severity. We collected data about emotional regulation, alexithymia, autistic symptoms and depression/anxiety in a sample of 64 young adults with ASD. We constructed two serial multiple mediator models, using autistic features as the independent variable and anxiety/depression symptoms as outcome variables. The serial relationship between alexithymia and emotional regulation mediated associations between autistic features and depression and anxiety, separately. The findings suggest that targeting alexithymia may benefit therapies designed to alleviate mood disorders in ASD.

Misremembrance of Things Past: Depression Is Associated With Difficulties in the Recollection of Both Specific and Categoric Autobiographical Memories.

Impaired retrieval of specific, autobiographical memories of personally experienced events is characteristic of major depressive disorder (MDD). However, findings in subclinical samples suggest that the reduced specificity phenomenon may reflect a broader impairment in the deliberate retrieval of all autobiographical memory types. This experiment (N = 68) explored this possibility by requiring individuals with and without MDD to complete a cued-recall task that required retrieval of specific, single-incident memories to a block of cues; retrieval of categoric, general memories to a block of cues; and to alternate between retrieval of specific and general memories for a block of cues. Results demonstrated that relative to never-depressed controls, individuals with MDD experience reduced recall of both specific (d = 0.48) and general memories (d = 1.00) along with reduced flexibility in alternating between specific and general memories (d = 0.90). Findings support further development of autobiographical memory-based interventions that target a range of retrieval deficits rather than specificity alone.

The influence of mood and attitudes towards eating on cognitive and autobiographical memory flexibility in female university students.

Cognitive flexibility, as measured through set-shifting ability, appears to be impaired in patients with eating disorders (EDs). Thus, it is important to determine if the switching deficit seen in clinical eating disorders generalizes to participants with a subclinical disordered eating. Another deficit manifested by clinical and subclinical disordered eating is the ability to retrieve specific autobiographical memories. It is possible that deficits in autobiographical memory retrieval extends to the ability to shift between retrieving specific versus general autobiographical memory information, a function important for problem -solving and emotion regulation. Therefore, the aims of the present study were to determine whether deficits in set-shifting are evident in a non-clinical sample of female university students with eating concerns, and whether inflexibility is also manifested in autobiographical memory retrieval. Sixty-nine female undergraduate students completed a measure of autobiographical memory flexibility, a set-shifting task (Brixton Spatial Anticipation Test) and measures of mood, ruminative thinking, and eating habits. After controlling for mood and rumination, bulimic traits predicted set-shifting ability and flexibility in autobiographical memory retrieval. Thus, flexibility deficits appear to manifest at the subclinical level, are evident in different domains, and appear to be related to bulimic traits, such as binge eating.

Understanding the relationship between suicidality, current depressed mood, personality, and cognitive factors.

OBJECTIVES: Links between suicidality and depressed mood are well established. There is, however, little information about the emotional regulation processes that underlie the relationship between suicidality and current low mood, and how these processes differ between groups of never-suicidal (NS), suicidal ideators, and suicide attempters. As suicidality and depression are heterogeneous constructs, this study aimed to conduct within- and between-group comparisons of known suicide risk factors that are associated with emotion regulation (neuroticism, trait aggression, brooding, impulsivity, and overgeneral autobiographical memories). DESIGN: Correlational design using between- and within-group comparisons from self-report measures. METHODS: Inter- and intragroup differences were identified using Pearson's correlation coefficients and tests of difference. An analysis of indirect effects was used to investigate whether the relationship between suicidality and current low mood was mediated by neuroticism, trait aggression, brooding, impulsivity, and overgeneral autobiographical memories, and if this relationship varied according to group type. RESULTS: Brooding appeared to be a consistent feature of all three groups and was closely related to current low mood. Compared to the NS group, the relationship between suicide attempts and current low mood showed greater associations with brooding, trait aggression, and overgeneral autobiographical memories. Compared to the NS group, the suicidal ideation group showed stronger associations with neuroticism and impulsivity, but these factors did not correlate with low mood. CONCLUSION: These results suggest a need for larger studies to focus on heterogeneity within suicidal populations and consider how different combinations of risk factors may heighten or reduce suicide risk. PRACTITIONER POINTS: It is well known that the severity and intensity of suicide and depressed presentations vary because of underlying dispositional and contextual factors (Fried & Nesse, ) which, in turn, affect how events are interpreted and responded to. Despite this, there is little research about how these mechanisms operate in different types of suicide groups, and their influence on the relationship between suicidality and current low mood. Understanding interrelationships that affect current low mood is of clinical significance because past suicidal history and deteriorations in already negative mood are linked to repeated suicide attempts and completion. Our findings show that ruminative brooding, defined as a tendency to repeatedly think about emotional aspects of an event, consistently correlates with current low mood across different types of suicidal groups (NS, suicidal ideators, and suicide attempters), and across analyses. Findings also show that suicidal ideation and attempt groups were associated with specific personality characteristics that increased the propensity of emotional responding and interpretation compared to the NS group. The relationship between suicide attempt and current low mood had a higher propensity to be influenced by trait aggression, brooding, and overgenerality compared to the NS group. In contrast, although the suicidal ideation group correlated more strongly with neuroticism and impulsivity, these factors did not influence current low mood. In terms of clinical practice, these findings imply that specific styles of interpretation and thinking may maintain the relationship between suicidality and current low mood. Given the cross-sectional nature of the study, however, it is not possible to imply causality. Nevertheless, the findings obtained provide some support for transdiagnostic models of cognitive-behavioural processes that could be developed further.

Autobiographical memory specificity in response to verbal and pictorial cues in clinical depression.

BACKGROUND: Depressed individuals have been consistently shown to exhibit problems in accessing specific memories of events from their past and instead tend to retrieve categorical summaries of events. The majority of studies examining autobiographical memory changes associated with psychopathology have tended to use word cues, but only one study to date has used images (with PTSD patients). OBJECTIVE: to determine if using images to cue autobiographical memories would reduce the memory specificity deficit exhibited by patients with depression in comparison to healthy controls. METHODS: Twenty-five clinically depressed patients and twenty-five healthy controls were assessed on two versions of the autobiographical memory test; cued with emotional words and images. RESULTS: Depressed patients retrieved significantly fewer specific memories, and a greater number of categorical, than did the controls. Controls retrieved a greater proportion of specific memories to images compared to words, whereas depressed patients retrieved a similar proportion of specific memories to both images and words. LIMITATIONS: no information about the presence and severity of past trauma was collected. CONCLUSIONS: results suggest that the overgeneral memory style in depression generalises from verbal to pictorial cues. This is important because retrieval to images may provide a more ecologically valid test of everyday memory experiences than word-cued retrieval..

Investigating the role of future thinking in social problem solving.

BACKGROUNDS AND OBJECTIVES: There is well-established evidence that both rumination and depressed mood negatively impact the ability to solve social problems. A preliminary stage of the social problem solving process may be the process of catapulting oneself forward in time to think about the consequences of a problem before attempting to solve it. The aim of the present study was to examine how thinking about the consequences of a social problem being resolved or unresolved prior to solving it influences the solution of the problem as a function of levels of rumination and dysphoric mood. METHOD: Eighty six participants initially completed the Beck Depression Inventory- II (BDI-II) and the Ruminative Response Scale (RRS). They were then presented with six social problems and generated consequences for half of the problems being resolved and half of the problems remaining unresolved. Participants then solved some of the problems, and following a delay, were asked to recall all of the consequences previously generated. RESULTS: Participants reporting higher levels of depressed mood and rumination were less effective at generating problem solutions. Specifically, those reporting higher levels of rumination produced less effective solutions for social problems that they had previously generated unresolved than resolved consequences. We also found that individuals higher in rumination, irrespective of depressed mood recalled more of the unresolved consequences in a subsequent memory test. LIMITATIONS: As participants did not solve problems for scenarios where no consequences were generated, no baseline measure of problem solving was obtained. CONCLUSIONS: Our results suggest thinking about the consequences of a problem remaining unresolved may impair the generation of effective solutions in individuals with higher levels of rumination.

A preliminary study of gender differences in autobiographical memory in children with an autism spectrum disorder.

Autobiographical memory was assessed in 24 children (12 male, 12 female, aged between 8 and 16 years) with autism spectrum disorder (ASD) and a comparison group of 24 typically developing (TD) children matched for age, IQ, gender and receptive language. Results suggested that a deficit in specific memory retrieval in the ASD group was more characteristic of male participants. Females in both the TD and ASD groups generated more detailed and emotional memories than males. They also demonstrated superior verbal fluency scores; verbal fluency and autobiographical memory cueing task performance were significantly positively correlated in females. Results are discussed in light of recent research suggesting gender differences in the phenotype of ASD.

Sex differences in interpretation bias in adolescents.

Interpretation biases, in which ambiguous information is interpreted negatively, have been hypothesized to place adolescent females at greater risk of developing anxiety and mood disorders than same-aged males. We tested the hypothesis that adolescent girls interpret ambiguous scenarios more negatively, and/or less positively, than same-aged males using the Adolescent Interpretation and Belief Questionnaire (N = 67, 11-15 years old). We also tested whether adolescent girls and boys differed in judging positive or negative interpretations to be more believable and whether the scenario content (social vs. non-social) affected any sex difference in interpretation bias. The results showed that girls had higher average negative interpretation scores than boys, with no sex differences in positive interpretation scores. Girls and boys did not differ on which interpretation they found to be most believable. Both sexes reported that positive interpretations were less likely to come to mind, and were less believable, for social than for non-social scenarios. These results provide preliminary evidence for sex differences in interpretation biases in adolescence and support the hypothesis that social scenarios are a specific source of anxiety to this age group. A greater understanding of the aetiology of interpretation biases will potentially enhance sex- and age-specific interventions for anxiety and mood disorders.

An "alternating instructions" version of the Autobiographical Memory Test for assessing autobiographical memory specificity in non-clinical populations.

There is limited research regarding how executive processes contribute to key cognitive deficits in depression, particularly impoverished retrieval of autobiographical memory. This study tested a novel version of the Autobiographical Memory Test (AMT), the "Alternating Instructions" AMT (AMT-AI), to determine how participants could flexibly retrieve specific and categoric autobiographical memories. The AMT-AI consisted of a standard AMT (AMT-S), a categoric version of the AMT (AMT-R), and a section of alternating instructions (AI) in which the rules required the participant to alternate between retrieval of categoric and specific memories. A total of 49 university students completed the AMT-AI, and self-report measures of depressive symptomatology and ruminative thinking. Results showed that the mean proportion of specific memories recalled on the AMT-AI was significantly lower than on the AMT-S. Also, reduced memory specificity on the AMT-AI, but not the AMT-S, was significantly negatively correlated with increased scores on measures of depressive symptomatology and ruminative thinking. Collectively the data suggested that the AMT-AI, relative to the traditional AMT, may be more sensitive to memory specificity in non-clinical populations. Future research is warranted to further determine the psychometric properties and utility of the AMT-AI.

Development of autobiographical memory in children with autism spectrum disorders: deficits, gains, and predictors of performance.

Autobiographical memory (AM) was assessed in 63 children (aged 8-17 years) with an autism spectrum disorder (ASD) and compared with 63 typically developing children matched for age, gender, IQ, and verbal ability. A range of methodologies was employed for eliciting past experience with particular focus on the ability to recall (a) specific events, (b) the recent and remote past, and (c) semantic versus episodic memories across different lifetime periods. Results indicated that the ASD group manifested difficulties in retrieving specific memories to word cues and had poorer access to the remote past. Deficits were found in the context of intact recent memory and preserved general memory abilities, with some impairment of visual memory. Problems in retrieving episodic and semantic AMs across the life span were also evident. Qualitative analysis of memory reports suggested that the ASD group was less likely to refer to emotion in their remote memories but more likely to describe emotions in their recent memories. Important predictors of AM performance in the ASD group were central executive abilities, in particular cognitive flexibility and verbal fluency.

Reduced specificity of negative autobiographical memories in repressive coping.

The current study examined memory specificity of autobiographical memories in individuals with and without a repressive coping style. It seems conceivable that reduced memory specificity may be a way to reduce accessibility of negative experiences, one of the hallmark features of a repressive coping style. It was therefore hypothesized that repressors would show reduced specificity when retrieving negative memories. In order to study memory specificity, participants (N = 103) performed the autobiographical memory test. Results showed that individuals with a repressive coping style were significantly less specific in retrieving negative experiences, relative to control groups of low anxious, high anxious, and defensive high anxious individuals. This result was restricted to negative memory retrieval, as participants did not differ in memory specificity for positive experiences. These results show that repressors retrieve negative autobiographical memories in an overgeneral way, possibly in order to avoid negative affect.
