Impaired cognitive control may be an important vulnerability factor for depression. Moreover, impairments in cognitive control have been proposed as a crucial process underlying ruminative thinking. The present study investigates the influence of impaired cognitive control for emotional information on rumination and depressive symptoms in a prospective design with a 1 year follow up in a clinical sample. Thirty remitted depressed adults completed the Internal Shift Task (IST), a measure of cognitive control of emotional information, at baseline. Moreover, questionnaires measuring rumination (RRS) and depressive symptoms (BDI-II) were administered. One year later participants were contacted again and asked to complete the BDI-II and RRS. Mediation analyses showed a significant influence of impaired cognitive control for emotional information at baseline on depressive symptoms one year later, which was fully mediated by rumination. These findings underscore the importance of cognitive control abilities as a process underlying rumination and as a vulnerability factor for depression. They can stimulate translational research to improve the effectiveness of interventions that aim to decrease vulnerability by targeting cognitive control.

Cognitive control impairments have been identified as an underlying mechanism for rumination, a key predictor of depression. Literature suggests that cognitive control training (CCT) targeting working memory functioning can increase effectiveness of existing antidepressant treatments to reduce rumination. However, it remains unclear whether CCT can also be implemented as a preventive intervention for depression, increasing resilience. For this purpose, at-risk undergraduate students (high trait ruminators) were allocated to a CCT or active control condition, consisting of 10 online training sessions. Working memory functioning was assessed preceding and following the training and reactivity to a lab stressor was assessed directly following training. Finally, at four weeks follow-up, brooding--the maladaptive form of rumination--was re-assessed in response to a naturalistic stressor (examination period). Although we did not find direct transfer effects of CCT on working memory functioning, increase in working memory functioning following CCT was related to post-training brooding and resilience levels. Moreover, participants receiving CCT demonstrated lower stress reactivity in the lab and a decrease in brooding following a naturalistic stressor at follow-up, indicating temporal stability of our findings. These findings suggest that CCT can be considered a promising preventive intervention to reduce stress reactivity and rumination.

Attentional bias for emotional information in older adults: the role of emotion and future time perspective.

Ineke Demeyer; Rudi De Raedt

Objectives Research suggests that older adults display a positivity bias at the level of information processing. However, because studies investigating attentional bias for emotional information in older adults have produced mixed findings, research identifying inter-individual differences that may explain these inconsistent results is necessary. Therefore, we investigated whether mood, symptoms of depression, symptoms of anxiety and future time perspective are related to attentional bias in older adults. Method Thirty-seven healthy older adults and 25 healthy middle-aged adults completed questionnaires to assess mood, symptoms of depression, symptoms of anxiety and future time perspective. Attentional bias towards happy, sad and neutral information was measured using a modified exogenous cueing paradigm with long cue presentations, to measure maintained attention versus avoidance of emotional stimuli. Results Older adults showed attentional avoidance for all emotional faces, whereas no attentional biases were found in the middle-aged group. Moreover, in the older adult group, avoidance for negative information was related to anxiety. Future time perspective was unrelated to attentional bias. Discussion These findings suggest that anxiety may lead to inter-individual differences in attentional bias in older adults, and that avoidance from negative information may be an emotion regulation strategy.

Cognitive control plays a key role in both adaptive emotion regulation, such as positive reappraisal, and maladaptive emotion regulation, such as rumination, with both strategies playing a major role in resilience and well-being. As a result, cognitive control training (CCT) targeting working memory functioning may have the potential to reduce maladaptive emotion regulation and increase adaptive emotion regulation. The current study explored the effects of CCT on positive reappraisal ability in a lab context, and deployment and efficacy of positive appraisal and rumination in daily life. A sample of undergraduates (n = 83) was allocated to CCT or an active control condition, performing 10 online training sessions over a period of 14 days. Effects on regulation of affective states in daily life were assessed using experience sampling over a 7-day posttraining period. Results revealed a positive association between baseline cognitive control and self-reported use of adaptive emotion regulation strategies, whereas maladaptive emotion regulation strategies showed a negative association. CCT showed transfer to working memory functioning on the dual n-back task. Overall, effects of CCT on emotion regulation were limited to reducing deployment of rumination in low positive affective states. However, we did not find beneficial effects on indicators of adaptive emotion regulation. These findings are in line with previous studies targeting maladaptive emotion regulation but suggest limited use in enhancing adaptive emotion regulation in a healthy sample.

The Effect of Future Time Perspective Manipulation on Affect and Attentional Bias

Ineke Demeyer; Rudi De Raedt

Socioemotional selectivity theory proposes that decreased future time perspective would lead to an emphasis on goals of well-being, with attentional preference for positive information. We developed a procedure to manipulate future time perspective, based on mental imagery, to experimentally investigate its effects on attention and affect. In experiment 1, we tested a new measure of future time perspective, the scrambled sentence test. In experiment 2, 41 undergraduates were randomly assigned to the imagery procedure with either short-term or long-term future scenarios. Attentional bias was measured by an exogenous cueing task. Between-group differences were found on the scrambled sentence test, indicating that the manipulation induced a different future time perspective in the long-term future imagery group compared to the short-term future imagery group. Although there were no differences in attentional bias at group level, a more expansive future time perspective after the manipulation correlated with more avoidance of negative information. These results indicate that future time perspective is related to information processing, which may point to an affect regulation strategy.

Cognitive theories emphasize the importance of attentional biases in the development and maintenance of depression. Noteworthy, recent studies indicate that depression-related biases only occur in later stages of attentional processing. This is consistent with the idea that attention is a multicomponent process, consisting of at least two mechanisms: selection and inhibition. Therefore, this study aims to investigate interference and inhibition toward angry and happy stimuli in dysphoric adolescents compared to nondysphoric adolescents. To examine interference and inhibition of emotional information in 21 dysphoric (17 girls) and 28 nondysphoric adolescents (17 girls), 10–16 years of age, a Negative Affective Priming task was used. In this task, a target has to be evaluated as positive or negative while ignoring a distractor. As expected, dysphoric adolescents showed both higher interference from and higher inhibition of angry stimuli relative to nondysphoric adolescents. In contrast, happy stimuli did not lead to interference and consequently did not have to be inhibited in either group. Finally, a positive relation was found between interference and the subsequent inhibition of emotional stimuli. These observations confirm the existence of a bias toward angry faces in dysphoric adolescents and indicate a higher inhibition of angry faces in dysphoric adolescents compared to nondysphoric adolescents. The obtained results are different from those of similar previous studies in depressed or dysphoric adults using sad faces or negatively valenced words and might reveal important emotion-specific or age-specific inhibitory biases.

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

Ineke Demeyer; Alvaro Sanchez; Rudi De Raedt

BACKGROUND AND OBJECTIVES Older 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. METHODS Sixty 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. RESULTS Changes 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. LIMITATIONS The stressor was only partially effective as it led to changes in calm mood, but not in nervous mood. CONCLUSIONS These 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.

Autonomic regulation in response to stress: The influence of anticipatory emotion regulation strategies and trait rumination.

According to the neurocognitive framework for regulation expectation, adaptively regulating emotions in anticipation of a stressful event should help individuals deal with the stressor itself. The goal of this study was twofold: first, the authors compared the influence of adaptive versus maladaptive anticipatory emotion regulation (ER) on the autonomic system during anticipation of, confrontation with, and recovery from a stressor; second, they explored whether trait rumination moderated this relationship. The authors collected data from 56 healthy female undergraduates during a public speaking task. The task involved 4 phases: baseline, anticipatory ER, stressor, and recovery. Participants were assigned to 1 of 2 anticipatory ER instructions (reappraisal or catastrophizing). Heart rate variability (HRV) indexed autonomic regulation. Results confirmed that HRV was higher in the reappraisal than in the catastrophizing group (over all time points, except for baseline). Trait rumination levels moderated the effect of anticipatory ER strategy on HRV during the stressor phase. Specifically, whereas for low ruminators reappraisal (versus catastrophizing) in the anticipation phase led to higher HRV when confronted to the stressor, high ruminators demonstrated lower HRV in that same condition. To conclude, over all participants, using reappraisal during the anticipation phase allowed participants to better cope with stress. However, only low, but not high ruminators could profit from the beneficial effect of anticipatory reappraisal on autonomic regulation. Even though further research is needed, this study suggests that, in female undergraduates, the tendency to ruminate is associated with abnormal anticipatory ER that might hinder an adaptive response to a stressor.

The role of personality in the assessment of subjective and physiological emotional reactivity : a comparison between younger and older adults

Priska Steenhaut; Ineke Demeyer; Rudi De Raedt; Gina Rossi

This study brings more clarity on the inconsistent findings on emotional reactivity differences between older (OA) and younger (YA) adults, by examining the influence of (mal)adaptive personality traits on emotional reactivity and by applying several assessment methods. We recruited 60 YA (25-50 years) and 60 OA (65+ years) from a nonclinical population. We used Visual Analogue Scales to measure subjective reactivity, and facial electromyography (corrugator and zygomaticus reactivity), heart rate, heart rate variability, and skin conductance level to assess physiological reactivity during happy and sad film clips. Results showed that personality influences on emotional reactivity in OA were largely comparable to YA, although the influence of negative emotionality and neuroticism on subjective reactivity in response to the sad film was significantly stronger in OA. It is thus important to assess both subjective and physiological reactivity when comparing age-related differences in OA and YA given the differential relation with personality features.

Assessment of Implicit Self-Esteem in Older Adults: The Role of Actual and Ideal Self-Esteem in Negative Mood:

Ineke Demeyer; Nuria Romero Martin; Rudi De Raedt

The interplay between actual and ideal self-esteem may be a key component in emotional disorders. Since automatic self-evaluations are not always consciously accessible, assessment through implicit measures is necessary. Given the lack of implicit self-esteem measures in late life, we aimed to identify a reliable measure and to clarify the role of actual and ideal self-esteem in mood and depressive symptoms in older adults. Forty-nine older adults completed two adapted Go/No go Association tasks measuring implicit actual and ideal self-esteem and measures of mood and depressive symptoms. The two Go/No go Association tasks showed satisfactory internal consistency. Moderation analyses revealed that lower actual self-esteem in older adults is related to higher levels of sad mood when ideal self-esteem is high. Moreover, lower actual self-esteem is related to more anxious mood. Given the role of self-esteem in emotional well-being, a reliable measure for older adults is crucial to improve age-appropriate diagnostics and treatment.
