Effects of dysphoria and induced negative mood on the processes underlying hindsight bias

Hindsight bias is the tendency to overestimate one’s prior knowledge of facts or events once the actual facts or events are known. Several theoretical frameworks suggest that affective states might influence hindsight bias. Nondysphoric participants (n?=?123, BDI?≤?13) in negative or neutral mood, and dysphoric participants (n?=?19, BDI?>?13) generated and recalled answers to difficult knowledge questions. All groups showed hindsight bias, that is, their recalled estimates were closer to the correct answer when this answer was shown at recall. Multinomial modelling revealed, however, that under dysphoria and induced negative mood different processes contributed to hindsight bias. Dysphoria, but not induced negative mood, was associated with a stronger reconstruction bias, compared with neutral mood. A recollection bias appeared in neutral, but neither in induced negative nor dysphoric mood. These findings highlight differences between the cognitive consequences of dysphoria and induced negative mood.     

Mood-related self-schemata and mood-congruity effects in autobiographical memory: A study of women with premenstrual syndrome

Everyday autobiographical memory and mood interactions were explored in a small clinical sample of women with premenstrual syndrome (PMS) and a matched control group. Subjects kept daily records of memorable events for two consecutive menstrual cycles. Two recognition memory tests were given after a one-cycle delay. Mood, or affect, was self-assessed retrospectively over a week, at the end of each day during data collection and at testing, and when events occurred. Women with PMS were more depressed and more negative (angry) than positive (experiencing bursts of energy) in their daily moods than controls. Memory accuracy was poorer overall for PMS than control subjects, although no direct effects of menstrual cycle phase on memory were found. Instead, mood affected memory indirectly through moodrelated self-schemata which subsequently mediated mood-congruity effects. Memory accuracy for events experienced in negative mood states and associated with negative affective reactions was higher for PMS subjects when tested in negative mood states than for controls. No group differences were found on events associated with positive affect or positive daily moods when mood state at the time of testing was also positive. Women with PMS processed information selectively from negative events and events experienced in negative moods compared to controls. Negative events and negative moods appeared to interfere with remembering for control subjects. Women in the control group appeared to be biased towards selectively remembering positive events and events experienced on days when their mood states were relatively positive.     

Mood Regulation and Memory: Repairing Sad Moods with Happy Memories

A total of 106 undergraduates participated in a study examining how individuals retrieve memories to repair negative moods. Participants first completed a measure of depression. Two weeks later, participants were assigned to either a sad or neutral mood induction. After mood induction, they recalled two memories, rated their affective responses to the memories, and indicated why they chose the valence and order of the memories. Consistent with mood-congruent recall, participants in the sad condition reported sadder memories than those in the neutral condition. However, participants with prior low depression scores tended to recall more positive second memories, whereas participants with higher prior depression scores recalled consecutive negative memories. Sixty-eight per cent of sad participants who retrieved a negative first and positive second memory mentioned mood repair as motivating the recruitment of the more positive second memory.     

Cognitive consequences of timeframe bias. On the link between working memory,cognitive switching,and time perspective

The present study examined how time perspective is associated with working memory updating and cognitive switching. Additionally, stress states and mood as potential mediators of the relationship between time perspective and cognitive performance were analysed. During two sessions participants (n = 200) completed a set of questionnaires measuring time perspective, task-related stress states, and mood. Moreover, in two separate sessions they performed working memory updating and switching tasks. The results indicated that two time perspectives, i.e. Present Fatalism and Past Positive, were associated with updating. Furthermore, mediation analysis showed that positive mood accounted for these relationships. Specifically, Present Fatalism was correlated with low positive mood and in turn, worse working memory scores, whereas Past Positive was associated with high positive mood leading to better performance on the working memory task. None of the time perspective dimensions correlated with cognitive switching. These findings shed more light on the cognitive consequences of timeframe bias and suggest new approaches in research on time perspective and cognitive functioning.

     

Decision mechanisms underlying mood-congruent emotional classification

There is great interest in understanding whether and how mood influences affective processing. Results in the literature have been mixed: some studies show mood-congruent processing but others do not. One limitation of previous work is that decision components for affective processing and responses biases are not dissociated. The present study explored the roles of affective processing and response biases using a drift-diffusion model (DDM) of simple choice. In two experiments, participants decided if words were emotionally positive or negative while listening to music that induced positive or negative mood. The behavioural results showed weak, inconsistent mood-congruency effects. In contrast, the DDM showed consistent effects that were selectively driven by an a-priori bias in response expectation, suggesting that music-induced mood influences expectations about the emotionality of upcoming stimuli, but not the emotionality of the stimuli themselves. Implications for future studies of emotional classification and mood are subsequently discussed.

Dynamic measures of anxiety-related threat bias: Links to stress reactivity

Exaggerated attention to threatening information, or the threat bias, has been implicated in the development and maintenance of anxiety disorders. Recent research has highlighted methodological limitations in threat bias measures, such as temporal insensitivity, leading to the development of novel metrics that capture change and variability in threat bias over time. These metrics, however, have rarely been examined in non-clinical samples. The present study aimed to explore the utility of these trial-level metrics in predicting anxiety-related stress reactivity (stress-induced negative mood state) in trait anxious adults (N?=?52). Following a stressor, participants completed the dot probe task to generate threat bias scores. Stress reactivity was measured via stress-induced changes in subjective mood state. More variability in trial-level bias scores (TL-BSs) and greater bias away from threat (both mean and peak negative TL-BSs) predicted increased stress reactivity. The temporal characteristics of threat bias and implications for clinically-relevant measurement are discussed.     

The role of rumination,attentional biases and stress in psychological distress

This experimental study examines the relationship between rumination and attentional bias. Additionally, the study aims to determine, within a diathesis‐stress framework, whether rumination or attentional bias (or both) can prospectively predict psychological distress. Eighty‐one participants completed selected measures of rumination and psychological distress at time one, in addition to experimental manipulations of rumination and mood, and measures of mood and attentional bias at time two. Seventy‐three participants (90% follow‐up) completed final measures of stress and psychological distress approximately 3 weeks later. In combination with negative mood, inducing rumination decreased positive attentional bias, whilst inducing distraction increased positive attentional bias. Rumination and stress interacted to predict change in psychological distress. Negative attentional bias showed a trend towards interacting with rumination and stress to predict dysphoria. The findings supported the proposed diathesis‐stress models. In addition, a causal relationship between rumination and positive attentional bias has been empirically established for the first time.     

Cognitive bias in acute stress disorder

Cognitive bias was investigated in survivors of motor vehicle accidents with either acute stress disorder (ASD; n=17) or no ASD (n=17). Participants completed the acute stress disorder interview, the Beck depression inventory, the Beck anxiety inventory, the impact of event scale, and a probability questionnaire (PQ) and a cost questionnaire (CQ) within four weeks of their accident. ASD participants exaggerated both the probability of negative events occurring, and the adverse cost of those events more than non-ASD participants. IES-Avoidance scores were the only significant predictors of both PQ and CQ scores. Findings are discussed in terms of the role of cognitive errors in posttraumatic adjustment.     

Are mood states bipolar?

Aims were (a) to test whether or not mood state factors are bipolar when response styles are controlled, and (b) to test whether the mood states conform to a circular order Intensity ratings were collected from 204 college students on a 63-adjective scale defining nine moods. Another sample of 127 rated their moods on modified four-category certainty scales. Factor analyses of the 63 adjective correlations disclosed seven monopolar factors. When acquiscence was controlled, the analysis yielded four bipolar and one monopolar mood states. The analyses of the data collected on the modified ratings form, which minimized response bias, disclosed three bipolar moods (composed-anxious, energetic-tired, agreeable-grouchy) and two monopolar states (cheerful and dejected). The hypothesis of a circular order of mood states received some support.     

Current negative mood encourages changes in end-of-life treatment decisions and is associated with false memories

To investigate the effects of mood on people's end-of-life treatment decisions and their false memories of those decisions, participants took part in two sessions. At Time 1, participants were experimentally induced into positive or negative moods. They decided whether they would want to receive or refuse treatments in a range of hypothetical medical scenarios, such as tube feeding while in a coma. Four weeks later, at Time 2, participants were induced into the same or the opposite mood and made these decisions a second time. They also recalled their previous decisions. Participants in negative moods at Time 2 changed more of their current decisions and falsely remembered more of their previous decisions than participants in positive moods. These findings suggest that people's current moods influence whether they change their treatment decisions; current decisions in turn bias recall of past decisions.     

Emotional language processing: how mood affects integration processes during discourse comprehension

This research tests whether mood affects semantic processing during discourse comprehension by facilitating integration of information congruent with moods’ valence. Participants in happy, sad, or neutral moods listened to stories with positive or negative endings during EEG recording. N400 peak amplitudes showed mood congruence for happy and sad participants: endings incongruent with participants’ moods demonstrated larger peaks. Happy and neutral moods exhibited larger peaks for negative endings, thus showing a similarity between negativity bias (neutral mood) and mood congruence (happy mood). Mood congruence resulted in differential processing of negative information: happy mood showed larger amplitudes for negative endings than neutral mood, and sad mood showed smaller amplitudes. N400 peaks were also sensitive to whether ending valence was communicated directly or as a result of inference. This effect was moderately modulated by mood. In conclusion, the notion of context for discourse processing should include comprehenders’ affective states preceding language processing.     

The turban effect: The influence of Muslim headgear and induced affect on aggressive responses in the shooter bias paradigm

Does Islamic appearance increase aggressive tendencies, and what role does affect play in such responses? In a computer game, participants made rapid decisions to shoot at armed people, some of whom wore Islamic head dress. We predicted and found a significant bias for participants to shoot more at Muslim targets. We also predicted and found that positive mood selectively increased aggressive tendencies towards Muslims, consistent with affect-cognition theories that predict a more top-down, stereotypical processing style in positive mood. In contrast, induced anger increased the propensity to shoot at all targets. The relevance of these results for our understanding of real-life negative reactions towards Muslims is discussed, and the influence of affective states on rapid aggressive responses is considered.     

Delineating potential mechanisms of implicit alcohol cognitions: drinking restraint, negative affect, and their relationship with approach alcohol associations

Problem drinkers may use alcohol to avoid negative mood states and may develop implicit cognitive associations between negative emotional states and reinforcing properties of drinking. It is paradoxical that attempts to control drinking, such as among those high in drinking restraint, may inadvertently increase desire to drink and subsequent alcohol consumption, and this may be exaggerated under times of emotional distress when urges to drink are high. We examined whether individuals who are high on drinking restraint would demonstrate stronger alcohol-related thoughts elicited by stimuli that represent the desire to use alcohol, in response to stronger versus weaker negative mood arousal. Seventy hazardous drinkers completed measurements of drinking restraint, alcohol consumption, and consequences of use. After being randomized to view negative or positive pictures sets, participants completed an Implicit Association Task (IAT) to test differences in the strength of the association between desire to approach or avoid alcohol or water cues, and then a measurement of subjective craving following the IAT. Regression analyses showed that trait restriction not temptation was positively related to IAT scores, after controlling for relevant covariates and explained 7% of the total variance. Trait temptation not IAT predicted subjective craving. Negative affect was unrelated to IAT scores, singly or in conjunction with measures of drinking restraint, contrary to predictions. In sum, implicit alcohol cognitions are related to attempts to restrict drinking not temptation to drink and are less strongly influenced by mood state.     

Developing a measure of interpretation bias for depressed mood: An ambiguous scenarios test

The tendency to interpret ambiguous everyday situations in a relatively negative manner (negative interpretation bias) is central to cognitive models of depression. Limited tools are available to measure this bias, either experimentally or in the clinic. This study aimed to develop a pragmatic interpretation bias measure using an ambiguous scenarios test relevant to depressed mood (the AST-D).¹ In Study 1, after a pilot phase (N = 53), the AST-D was presented via a web-based survey (N = 208). Participants imagined and rated each AST-D ambiguous scenario. As predicted, higher dysphoric mood was associated with lower pleasantness ratings (more negative bias), independent of mental imagery measures. In Study 2, self-report ratings were compared with objective ratings of participants’ imagined outcomes of the ambiguous scenarios (N = 41). Data were collected in the experimental context of a functional Magnetic Resonance Imaging scanner. Consistent with subjective bias scores, independent judges rated more sentences as negatively valenced for the high versus low dysphoric group. Overall, results suggest the potential utility of the AST-D in assessing interpretation bias associated with depressed mood.

Psychological changes over the course of pregnancy: a study of attitudes toward the fetus/neonate

Pregnant women's attitudes towards their fetus over the course of the pregnancy were studied in relation to physiological events of pregnancy, namely seeing the fetus via ultrasound and experiencing fetal movement. A consecutive series of primiparae (n = 129) was randomly assigned, at recruitment between 10 and 14 weeks menstrual age, to conditions of high (n = 67) or low (n = 62) feedback real time ultrasound. Thereafter, women were assessed at 16 and 32 weeks gestation, within 24 hours of delivery and by questionnaire at 3 months postpartum. On each occasion women completed attitude rating scales concerning their pregnancy and their fetus or neonate. These scales were subjected to principal components analysis and two main dimensions were derived for ratings of both attitudes towards the pregnancy and the fetus/neonate. No relationship was found between factor scores and ultrasound feedback condition, although scores on the fetal attachment dimension showed a significant linear increase over the pregnancy. Women reporting fetal movement at 16 weeks displayed significantly higher scores on the fetal-attachment dimension at all three assessment points. Multiple regression analyses were utilized to identify predictors of initial reactions to the neonate and attachment ratings at 3 months postpartum. At delivery, ratings of attachment to the neonate were related to drug requirements in labor and attachment ratings at 32 weeks. Reactions to the neonate at delivery and ratings of postpartum mood emerged as significant predictors of maternal attachment at 3 months postpartum. These results are discussed in the context of research attempting to establish the importance of postpartum bonding.
