Positive emotion modulates cognitive control: An event‐related potentials study

There is substantial evidence to indicate that negative emotion can modulate cognitive control processing. However, only a few studies have investigated this effect with positive emotion. Therefore, the present study explored the electrophysiological correlates of the impact of positive emotional stimuli on cognitive control, using event‐related potentials (ERPs). Sixteen healthy young adults completed a modified Simon task (Simon, 1969). Behavioral data indicated that reaction times were faster for positive emotional stimuli than for neutral emotional stimuli in the incongruent condition, but not in the congruent condition, which suggested that positive emotion expedited conflict resolution. The ERP data showed that two negative ERP components (N300–400 and N450–550) were associated with the positive emotional stimuli in the incongruent minus congruent condition. It is suggested that these components may respectively be related to the conflict monitoring (N300–400) and response selection (N450–550) stages of cognitive control processing. Overall, our results indicated that positive emotion could facilitate cognitive control processing. These results are in line with the neuropsychological theory, according to which, positive emotion could modulate cognitive control mediated by increased dopamine levels in frontal brain areas.     

Cognitive control in belief‐laden reasoning during conclusion processing: An ERP study

Belief bias is the tendency to accept conclusions that are compatible with existing beliefs more frequently than those that contradict beliefs. It is one of the most replicated behavioral findings in the reasoning literature. Recently, neuroimaging studies using functional magnetic resonance imaging (fMRI) and event‐related potentials (ERPs) have provided a new perspective and have demonstrated neural correlates of belief bias that have been viewed as supportive of dual‐process theories of belief bias. However, fMRI studies have tended to focus on conclusion processing, while ERPs studies have been concerned with the processing of premises. In the present research, the electrophysiological correlates of cognitive control were studied among 12 subjects using high‐density ERPs. The analysis was focused on the conclusion presentation phase and was limited to normatively sanctioned responses to valid–believable and valid–unbelievable problems. Results showed that when participants gave normatively sanctioned responses to problems where belief and logic conflicted, a more positive ERP deflection was elicited than for normatively sanctioned responses to nonconflict problems. This was observed from ?400 to ?200 ms prior to the correct response being given. The positive component is argued to be analogous to the late positive component (LPC) involved in cognitive control processes. This is consistent with the inhibition of empirically anomalous information when conclusions are unbelievable. These data are important in elucidating the neural correlates of belief bias by providing evidence for electrophysiological correlates of conflict resolution during conclusion processing. Moreover, they are supportive of dual‐process theories of belief bias that propose conflict detection and resolution processes as central to the explanation of belief bias.

Resilience as the ability to bounce back from stress: A neglected personal resource?

The purpose of this study was to examine resilience, as the ability to bounce back from stress, in predicting health-related measures when controlling for other positive characteristics and resources. We assessed resilience, optimism, social support, mood clarity, spirituality, purpose in life, and health-related measures in two large undergraduate samples. In Study 1, resilience was related to both health-related measures (less negative affect and more positive affect) when controlling for demographics and other positive characteristics. In Study 2, resilience was related to all four health-related measures (less negative affect, more positive affect, less physical symptoms, and less perceived stress) when controlling for the other variables. None of the other positive characteristics were related to more than three of the six possible health-related measures when controlling for the other variables. Resilience, as the ability to bounce back, may be an important personal resource to examine in future studies and target in interventions.     

In search of durable positive psychology interventions: Predictors and consequences of long-term positive behavior change

A number of positive psychology interventions have successfully helped people learn skills for improving mood and building personal resources (e.g., psychological resilience and social support). However, little is known about whether intervention activities remain effective in the long term, or whether new resources are maintained after the intervention ends. We address these issues in a 15-month follow-up survey of participants from a loving-kindness meditation intervention. Many participants continued to practice meditation, and they reported more positive emotions (PEs) than those who had stopped meditating or had never meditated. All participants maintained gains in resources made during the initial intervention, whether or not they continued meditating. Continuing meditators did not differ on resources at baseline, but they did show more PE and a more rapid PE response to the intervention. Overall, our results suggest that positive psychology interventions are not just efficacious but of significant value in participants’ real lives.     

Flourishing students: A longitudinal study on positive emotions,personal resources,and study engagement

The aim of this two-wave questionnaire study with a 4-week interval among 391 Dutch university students was to test a gain cycle of positive emotions, personal resources, and study engagement. As a theoretical basis, this study drew on the broaden-and-build (B&B) theory and the conservation of resources (COR) theory. More specifically, it was hypothesized that the experience of positive emotions predicts students’ future personal resources and study engagement. Moreover, it was expected that there is a longitudinal relationship between personal resources and study engagement. Furthermore, we hypothesized that positive emotions, personal resources, and study engagement are reciprocally related. Results, obtained by means of structural equation modeling, confirmed both causal (except for the positive relationship between positive emotions and study engagement) and reciprocal hypotheses, thereby successfully integrating the B&B theory with the COR theory.     

Emotional labor among trainee police officers: The interpersonal role of positive emotions

The aim of this study is to get an insight of the interpersonal process of emotional labor, and the role of positive emotions in the interaction between the sender and receiver, while taking both the perspective of the sender and the receiver into account. We tested the influence of the perceived display of positive emotions of Dutch trainee police officers (N?=?80) during an interaction with offenders on perceived authenticity and perceived performance success, incorporating the senders’ emotion regulation technique (i.e., deep acting and surface acting). Consistent with hypotheses, results of structural equation modeling analyses showed that perceived authenticity mediates the relationship between the perceived display of positive emotions and perceived performance success, while the specific senders’ emotion regulation technique was not related to perceived performance success. Furthermore, results showed that perceived performance success mediated the relationship between the perceived display of positive emotions and senders’ felt positive emotions after the interaction, controlling for senders’ positive affect.     

Mindfulness and positive affect: Cross-sectional,prospective intervention,and real-time relations

This study tested trait- and state-mindfulness and trait- and state-positive affect (PA) relations within a cross-sectional study (Study 1; N?=?174, 76% women, Mean (SD)_age?=?24 (2.7) years) and a randomized controlled 4-session mindfulness intervention study (Study 2; N?=?51, 65.4% women, Mean (SD)_age?=?25 (4.3) years). Study 1 : levels of trait-mindfulness and trait-like PA were related, as theorized, only among participants with meditation experience. Study 2 : Study 2 is a secondary analysis of a mindfulness intervention study [Tanay, Lotan, & Bernstein (2012). Salutary proximal processes and distal mood and anxiety vulnerability outcomes of mindfulness training: A Pilot preventive intervention. Behavior Therapy, 43, 492–505]. Unexpectedly, reduced levels of trait-like PA were observed pre- to post-intervention across conditions. No significant between-group mean differences were observed post-intervention. However, as expected, change in trait-mindfulness from pre- to post-intervention predicted change in trait-like PA among the intervention but not control condition. Second, levels of state-mindfulness during mindfulness meditation were positively related to levels of state-PA. The theoretical and applied implications of these findings for mindfulness and PA are discussed.     

Finding happiness in negative emotions: An experimental test of a novel expressive writing paradigm

Positive emotions are evoked on seeing one's favorite person. To investigate the psychological and physiological responses accompanying these positive emotions, we simultaneously recorded various parameters such as the mood state, heart rate, skin conductance level (SCL), serum levels of catecholamines, and proportions of T cells and natural killer (NK) cells among the lymphocytes while participants viewed films featuring their favorite persons. The participants reported that they felt better and invigorated; in addition, SCL and proportion of NK cells in peripheral blood increased significantly, and these physiological changes were positively correlated. These results suggest that positive emotions elicited on seeing a favorite person may lead to psychological and physiological activation and, more importantly, may promote health.

Self-perceived strengths among people who are homeless

This study examined self-perceived strengths among 116 people who were homeless. Those who had experienced a longer period of current homelessness tended to report fewer personal strengths (r?=??0.23). Nonetheless, in spite of their marginalized position in society, the vast majority of participants (114 out of 116) perceived personal strengths. A prior diagnosis with mental illness was not associated with the number of strengths reported, but self-perception of strengths was associated with altruistic orientation. The Values in Action (VIA) taxonomy of character strengths captured many of the responses generated by this population. The most frequently mentioned character categories included social intelligence, kindness, persistence, authenticity and humour. The most frequently mentioned other strengths included personal skills (e.g. music, sports), job skills, intelligence and education. The results have relevance for efforts to build self-perceptions that facilitate escape from homelessness.
