The effect of sad mood on early sensory event-related potentials to task-irrelevant faces

It has been shown that the perceiver’s mood affects the perception of emotional faces, but it is not known how mood affects preattentive brain responses to emotional facial expressions. To examine the question, we experimentally induced sad and neutral mood in healthy adults before presenting them with task-irrelevant pictures of faces while an electroencephalography was recorded. Sad, happy, and neutral faces were presented to the participants in an ignore oddball condition. Differential responses (emotional – neutral) for the P1, N170, and P2 amplitudes were extracted and compared between neutral and sad mood conditions. Emotional facial expressions modulated all the components, and an interaction effect of expression by mood was found for P1: an emotional modulation to happy faces, which was found in neutral mood condition, disappeared in sad mood condition. For N170 and P2, we found larger response amplitudes for both emotional faces, regardless of the mood. The results add to the previous behavioral findings showing that mood already affects low-level cortical feature encoding of task-irrelevant faces.

The effect of sad mood on subjective appraisal of memory performance in older people with and without subjective memory complaints: An experimental study

AbstractBackgroundSubjective memory complaints (SMC) have been identified as a possible precursor to cognitive decline and may indicate a need for an early intervention for at‐risk older adults. However, it is well‐established that low mood is associated with SMC, leading to claims that memory concerns in older people may often reflect primarily psychological symptoms. This study aimed to determine the effect of low mood on subjective memory appraisal in older adults.MethodWe used a film‐based mood induction procedure (MIP) to test the effect of sad vs. neutral mood on subjective appraisal of memory performance in an experimental 2X2 between‐subjects design. Participants were 98 cognitively unimpaired older people (n=45 with SMC), randomised to the sad MIP (n=56) or the neutral MIP (n=42). All participants completed measures of trait SMC and ruminative self‐focused attention (RSFA) as well as perceived performance and metacognitive experience (ME) following the MIP and completion of a face‐name and a maze‐learning task.ResultParticipants in the sad MIP condition (M=42.75, SD=30.97) reported significantly greater sadness than those in the neutral condition following the manipulation (M=11.57, SD=18.44). The association between objective and subjective memory performance was stronger for cued recall on the face‐name task (r=.61, p=.001) and was weaker free recall on the face‐name task (r=.26, p=0.016) as well on the maze‐learning task (r=‐.16, p=.200). Contrary to expectation, there was no significant effect of mood condition on perceived performance on Face‐Name learning task (MD=‐2.43, p=498), but sad mood was associated with better perceived performance on the maze‐learning task (MD=13.34, p=.015). Results also indicated that RSFA and ME were implicated as mechanisms in subjective memory performance appraisal.ConclusionFindings indicate that SMC is a complex multifaceted phenomenon which may be underpinned by maladaptive self‐regulation and attentional systems, suggesting that psychological interventions may be appropriate for many older adults with SMC.

Sad mood, emotion regulation, and response inhibition

ABSTRACT Affect-as-information models, resource allocation models, and arousal biased competition theory predict different effects of mood on cognition. To test these theories, this study examines the effect of sad mood on response inhibition (RI) and whether emotion dysregulation impacts this potential relationship. Participants were 273 undergraduates who wrote about either a typical day or a sad event from their life. They self-reported mood and emotion regulation difficulties, and RI was a composite score of Colour-Word Stroop, Stop-Signal, and go/no-go computerised tasks. The intensity of self-reported sad mood did not affect RI as predicted, but those who wrote about sad events had worse RI. Worse emotion regulation also predicted worse RI. Cognitive loads, rumination, and mind-wandering are discussed as possible mechanisms. Findings are extended from well-established areas such as working memory to the less-established area of RI.

Effects of induced sad mood on facial emotion perception in young and older adults

ABSTRACTOlder adults perceive less intense negative emotion in facial expressions compared to younger counterparts. Prior research has also demonstrated that mood alters facial emotion perception. Nevertheless, there is little evidence which evaluates the interactive effects of age and mood on emotion perception. This study investigated the effects of sad mood on younger and older adults’ perception of emotional and neutral faces. Participants rated the intensity of stimuli while listening to sad music and in silence. Measures of mood were administered. Younger and older participants’ rated sad faces as displaying stronger sadness when they experienced sad mood. While younger participants showed no influence of sad mood on happiness ratings of happy faces, older adults rated happy faces as conveying less happiness when they experienced sad mood. This study demonstrates how emotion perception can change when a controlled mood induction procedure is applied to alter mood in young and older participants.

Older adults' attentional deployment: Differential gaze patterns for different negative mood states

Background and objectivesOlder adults are characterized by an attentional preference for positive over negative information. Since this positivity effect is considered to be an emotion regulation strategy, it should be more pronounced when emotion regulation is needed. In contrast to previous studies that focused on the effects of sad mood on attention, we used a stressor to activate emotion regulation and evaluate the effects of different types of mood state changes. Moreover, we evaluated mood effects on attentional processes using a paradigm that allows disentangling between different attentional engagement and disengagement processes. MethodsSixty older adults were randomly assigned to receive a stressor or a control task. Before and after this manipulation, mood state levels (happy, sad, nervous, calm) were assessed. Next, attentional processing of happy, sad, and angry faces was investigated using an eye-tracking paradigm in which participants had to either engage their attention towards or disengage their attention away from emotional stimuli. ResultsChanges in different mood state levels were associated with different attentional disengagement strategies. As expected, older adults who increased in sad mood level showed a larger positivity effect as evidenced by a longer time to disengage attention from happy faces. However, older adults who received the tension induction and who decreased in calm mood level were characterized by longer times to disengage attention from sad faces. LimitationsThe stressor was only partially effective as it led to changes in calm mood, but not in nervous mood. ConclusionsThese results suggest that older adults may deploy a positivity effect in attention (i.e., longer times to disengage from positive information) in order to regulate sad mood, but that this effect may be hampered during the confrontation with stressors.

Using arterial spin labeling to examine mood states in youth.

IntroductionLittle is known about the neural correlates of mood states and the specific physiological changes associated with their valence and duration, especially in young people. Arterial spin labeling (ASL) imaging is particularly well-suited to study sustained cerebral states in young people, due to its robustness to low-frequency drift, excellent interscan reliability, and noninvasiveness. Yet, it has so far been underutilized for understanding the neural mechanisms underlying mood states in youth.MethodsIn this exploratory study, 21 healthy adolescents aged 16 to 18 took part in a mood induction experiment. Neutral, sad, and happy mood states were induced using film clips and explicit instructions. An ASL scan was obtained following presentation of each film clip.ResultsMood induction led to robust changes in self-reported mood ratings. Compared to neutral, sad mood was associated with increased regional cerebral blood flow (rCBF) in the left middle frontal gyrus and anterior prefrontal cortex, and decreased rCBF in the right middle frontal gyrus and the inferior parietal lobule. A decrease in self-reported mood from neutral to sad condition was associated with increased rCBF in the precuneus. Happy mood was associated with increased rCBF in medial frontal and cingulate gyri, the subgenual anterior cingulate cortex, and ventral striatum, and decreased rCBF in the inferior parietal lobule. The level of current self-reported depressive symptoms was negatively associated with rCBF change in the cerebellum and lingual gyrus following both sad and happy mood inductions.ConclusionsArterial spin labeling is sensitive to experimentally induced mood changes in healthy young people. The effects of happy mood on rCBF patterns were generally stronger than the effects of sad mood.

Effects of sad mood on autobiographical memory in older adults with and without lifetime depression

The main objective of this study was to determine whether reduced autobiographical memory specificity is also a marker for depression in older adults. To answer this question two experiments and a prospective longitudinal clinical study were executed with the autobiographical memory task (AMT) as measure for memory specificity. The objective of the 1st experimental study was to assess the influence of a negative mood induction versus the effect of multiple testing in a neutral condition in 58 never depressed (ND) elderly. In the 2nd experimental study a negative mood was induced in 63 participants remitted from depression (RD) compared to 60 matched ND controls. All participants were 55 and older. Lastly, the predictive value of the AMT for the course of depressive symptoms was assessed in the RD individuals over a 14-17 months follow-up (FU) period. Performance did not improve with repeated testing, but a trend was found suggesting fatigue. There was no difference between the RD and ND group on baseline AMT. The mood induction had no effect on the AMT regardless of clinical history. Changes in the level of depressive symptoms at the 14-month FU were predicted by residual symptoms at baseline and the number of previous depressive episode, but not by baseline AMT, changes in AMT or mood after mood induction. The results of this study suggest that memory specificity on the AMT may not be a useful marker for vulnerability for clinical depression in older adults.

The implicit memory of individual depression in percept-driven process under the influence of sad mood induction

Objective To investigate the effect of sad mood to implicit memory of depressed individuals under the condition of percept-driven process. Methods Using the percept-driven implicit paradigm improved by Paller,26 depression subjects and 25 normal subjects completed study-test task and reported the gender of different emotional faces. Results ①There were main effects of time(F = 4.61, P<0.05)and mood state(F= 21.61, P <0.05) ,significant interaction of time and emotion(F = 4. 13, P<0. 05) ,no significant difference of group on visual analogue scale(VAS) mood ratings. ②Among the accuracy rate of subjects' gender judging to different emotional faces,there were significant main effects on time(F = 4.12, P<0.05)and experiment type (F = 20.55, P < 0.05) , and there was significant interaction of time and experiment type (F=31.72,P<0.05). ③Further simple effects analysis showed that the positive((80 ± 13)%vs(92 ± 10)% , F=65.06, P<0.05) ,negative((58 ± 12)%vs(91 ±10)%,F=10.00,P<0.05),neutral((84±16)%vs(88±9)%, F= 12.49, P < 0. 05) faces when the presentation time was 3600ms in experiment type had significant simple effects; the positive ((76 ± 12)%vs(85±10)%,F=54.72, P<0.05) ,neutral((82 ± 10)% vs(80 ± 10)% , F = 54.57, P<0.05)faces when the presentation time was 300 ms in experiment types had significant simple effects, while the accuracy of neutral faces had significant simple effect between the two groups. Conclusion Sad mood enhance the implicit memory of both depressed and normal subjects to positive and negative faces,and the accuracy rate in implicit processing to neutral faces of depressed group were lower than that of normal group.

Effects of sad mood on facial emotion recognition in Chinese people

This study examined the influence of sad mood on the judgment of ambiguous facial emotion expressions among 47 healthy volunteers who had been induced to feel sad ( n = 13), neutral ( n = 15), or happy ( n = 19) emotions by watching video clips. The findings suggest that when the targets were ambiguous, participants who were in a sad mood tended to classify them in the negative emotional categories rather than the positive emotional categories. Also, this observation indicates that emotion-specific negative bias in the judgment of facial expressions is associated with a sad mood. The finding argues against a general impairment in decoding facial expressions. Furthermore, the observed mood-congruent negative bias was best predicted by spatial perception. The findings of this study provide insights into the cognitive processes underlying the interpersonal difficulties experienced by people in a sad mood, which may be predisposing factors in the development of clinical depression.

The Effects of Sad Mood on Reports of Parents’ Caregiving Behaviors

Two studies examined the hypothesis that recollections of parents’ child-rearing behaviors on the Parental Bonding Instrument (PBI: Parker, Tupling, & Brown, 1979) are influenced by current mood. Study 1 investigated the effects of sad versus neutral mood induction on PBI scores in 50 college students. Participants rated their parents as less caring following the sad mood induction than following the neutral induction. Study 2 investigated the effects of naturally occurring changes in depressive symptoms on PBI scores over a two month period. Changes in depressive symptoms correlated with changes in father care scores and tended to correlate with changes in mother care scores. Findings from both studies suggest that retrospective reports of parenting are susceptible to mood bias and highlight the limits of using cross sectional designs to explore the relationship between parenting and depression.

Effects of sad mood on time-based prospective memory

Very little is known about the influence of emotional factors on prospective memory (PM) performance. We used a mood induction (neutral or sad) to examine the effects of sad mood on time-based PM performance. Based on Ellis and Ashbrook's (1988) resource allocation model, we hypothesised an adverse effect of sad mood on PM performance. Results revealed that participants who responded to the sad mood induction procedure showed reduced PM performance that mainly resulted from a decreased timeliness of PM responses, but only in the first half of the task. Mood effects on PM could be explained in terms of reduced and less accurate monitoring. Implications for concepts of PM and the assessment of emotional after-effects are discussed.

Insights from sadness: A three-step model of the development of altruism as hedonism

Research into the effects of sad mood on prosocial action is reviewed and is used as a vehicle for examining the transformation of altruism from a punishing to a gratifying event. A three-step model of the socialization of altruism as a reinforcer is proposed. The model argues for (a) an initial stage (presocialization) in which altruism occurs rarely among young children because of its punishing function, (b) a second stage (awareness of norms) in which altruism functions as a mechanism for the receipt of positive sanctions, and (c) a final stage (internalization) in which, by adulthood, altruism has acquired a gratifying function through its status as a conditioned reinforcer. Evidence for the functional equivalence of self-gratification and adult altruism is also presented.
