RESUMO

Levels of COVID-19 stress have soared worldwide as a result of the pandemic. Given the pernicious psychological and physiological effects of stress, there is an urgent need for us to protect populations against the pandemic's psychological impact. While there exists literature documenting the prevalence of COVID-19 stress among various populations, insufficient research has investigated psychological factors that might mitigate this worrying trend. To address this gap in the literature, the current study seeks to examine executive functions as a potential cognitive buffer against COVID-19 stress. To do so, the study adopted a latent variable approach to examine three latent factors of executive functions and their relation to COVID-19 stress among a sample of 243 young adults. Structural equation models showed differential associations between COVID-19 stress and the latent factors of executive functions. While the latent factor of updating working memory was associated with attenuated COVID-19 stress, task switching and inhibitory control were not significantly associated with COVID-19 stress. These results further our understanding of the critical processes of executive functions and highlight the nuanced link between executive functions and pandemic-related stress.

RESUMO

With postmodern societies placing a strong emphasis on making full use of one's time, it is increasingly common to extol busy individuals as more achieving. In this context, although feeling a social expectation to be busy might imply that individuals are regarded as competent and desirable, its accompanying stressors may also detrimentally impact their mental health. Utilising data from a seven-day diary study, the current research examined the relationship between people's daily perceived pressure to be busy and their daily emotional wellbeing. Multilevel modelling revealed that daily social pressure to be busy was a significant predictor of daily negative affect, anxiety, and depressive symptoms at the within-person level. Of import, individuals' trait emotional complexity acceptance moderated these relationships, with those lower on emotional complexity acceptance reporting significantly higher negative affect, anxiety, and depressive symptoms on days they felt greater social pressure to be busy. These effects were not observed among those higher on emotional complexity acceptance. Together, the current findings suggest that social pressure to feel busy is generally related to poorer daily emotional wellbeing, and that those with higher trait emotional complexity acceptance have an advantage of maintaining their emotional wellbeing in the face of such a social pressure.

RESUMO

Social media, one of the most pervasive forms of technology, has been widely studied in relation to the mental health and well-being of individuals. However, the current literature on social media and well-being has provided mixed and inconclusive findings, thus creating a polarizing view of social media. These mixed findings continue to extend into the pandemic, with researchers debating over the effects of social media in the new norms of social isolation. In light of these inconclusive findings, the aim of our meta-analysis was to synthesize previous research data in order to have a holistic understanding of the association between social media and well-being, particularly in the present context of COVID-19. The current meta-analysis systematically investigated 155 effect sizes from 42 samples drawn from 38 studies published during the COVID-19 pandemic (N = 43,387) and examined the potential moderators in the relationship between social media and well-being, such as the different operationalizations of social media usage and demographics. Overall, our study found that the relationship between social media usage and well-being was not significant in the context of COVID-19. Additionally, the impact of various moderators on the relationship between social media and well-being was found to vary. We discuss the various theoretical, methodological and practical implications of these findings and highlight areas where further research is necessary to shed light on the complex and nuanced relationship between social media and well-being.

RESUMO

Despite difficulties in reading and writing, some research suggests that dyslexia may be related to higher levels of creativity. However, this pattern is not consistently observed. The current research sought to ascertain whether individuals with clinically diagnosed dyslexia exhibit higher creativity than controls through a meta-analysis. Fourteen studies that assessed the creativity of 397 individuals with clinically diagnosed dyslexia and 453 controls were reviewed. Random-effects meta-analysis revealed an overall non-significant difference in creativity scores between those with dyslexia and controls. Additionally, method factors such as the type of creativity task and whether intelligence was controlled for, as well as sample-related factors such as gender, did not explain differences in the dyslexia-creativity relationship. Nonetheless, individuals with dyslexia significantly outperformed controls in creativity scores in adult samples, but not in younger child/adolescent samples. Overall, the current findings provide limited support for the idea that individuals with dyslexia are more creative, and that past evidence of this relationship may be limited to adult samples.

RESUMO

Background: Childhood emotional abuse and neglect is linked with a host of adverse outcomes later in life, including depression. However, potential psychological resources that may mitigate the adverse outcomes of childhood emotional abuse and neglect are not well-understood.Aims: Drawing from the insight that having a sense of purpose can help individuals deal with setbacks and difficulties better, we propose that purpose in life can also help sufferers of childhood maltreatment cope more effectively and reduce the onset of depressive symptoms.Methods: Participants were drawn from two large, nationally representative studies comprising a total of 3664 respondents. Purpose in life, childhood emotional abuse and neglect, and depressive symptoms were measured with validated scales.Results: We found convergent evidence that purpose in life attenuates the effect of childhood emotional abuse and neglect on subsequent depressive symptoms across a range of measures of mood and depression.Conclusions: The current study highlights the important role played by purpose in life in building resilience, coping against adverse life events, and psychological well-being.

RESUMO

Socioeconomic status (SES) and bilingualism have been shown to influence executive functioning during early childhood. Less is known, however, about how the two factors interact within an individual. By analyzing a nationally representative sample of approximately 18,200 children who were tracked from ages 5 to 7 across four waves, both higher SES and bilingualism were found to account for greater performance on the inhibition and shifting aspects of executive functions (EF) and self-regulatory behaviors in classroom. However, only SES reliably predicted verbal working memory. Furthermore, bilingualism moderated the effects of SES by ameliorating the detrimental consequences of low-SES on EF and self-regulatory behaviors. These findings underscore bilingualism's power to enrich executive functioning and self-regulatory behaviors, especially among underprivileged children.

RESUMO

This study investigated conceptual representations changes in bilinguals. Participants were Indonesian-English bilinguals (dominant in Indonesian, with different levels of English proficiency) and a control group composed of English-dominant bilinguals. All completed a gender decision task, in which participants decided whether English words referred to a male or female person or animal. In order to explore conceptual representations, we divided the words into gender-specific and gender-ambiguous words. Gender-specific words were words in which conceptual representations contained gender as a defining feature, in both English and Indonesian (e.g., uncle). In contrast, gender-ambiguous words were words in which gender was a defining feature in English but not a necessary feature in Indonesian (e.g., nephew and niece are both subsumed under the same word, keponakan, in Indonesian). The experiment was conducted exclusively in English. Indonesian-English bilinguals responded faster to gender-specific words than gender-ambiguous words, but the difference was smaller for the most proficient bilinguals. As expected, English-dominant speakers' response latencies were similar across these two types of words. The results suggest that English concepts are dynamic and that proficiency leads to native-like conceptual representations.

RESUMO

Given elevated depression rates since the onset of the pandemic and potential downstream implications, this research examined the association between activity engagement and depression among middle-aged and older adults postlockdown. This study aimed to (a) identify activity engagement profiles among middle-aged and older adults, (b) understand factors associated with profile memberships, and (c) compare depression trajectories across profiles as COVID-19 restrictions eased over 16 months in Singapore. This longitudinal study involved 6,568 middle-aged and older adults. Latent growth analysis was first conducted to obtain estimates of depression trajectories for each individual. Latent profile analysis was then conducted to identify different activity profiles. Finally, profile characteristics and depression trajectories across these different profiles were compared. Results indicated four profiles that varied in social and physical activity. Although digital activity was negatively associated with depression at baseline, it did not explain depression trajectories as restrictions eased. Over time, depression decreased for all profiles; however, those who were inactive on all activities except digital contact tended to experience more persistent symptoms, compared with those who were highly engaged in physical and outdoor activities. Individuals who were only active digitally tended to experience more prepandemic negative affect, were more introverted and neurotic, less open, agreeable, and conscientious, and had worse health and mobility, lower income, and lower education. Findings highlight how imprecise conceptualizations of activity engagement may obscure subtle activity engagement-depression relations. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

RESUMO

Objective: The objective of this scoping review was to map the range of measurement tools used to study the prevalence of common mental health conditions in COVID-19 ICU survivors. Introduction: Increased rates of admission to and survivorship from intensive care units (ICUs) have been observed in recent years, particularly during the global pandemic. ICU patients are at a higher risk of developing depressive, anxiety, and PTSD symptoms. Due to the high burden of disease, an accurate understanding of long-term mental health challenges for this population is key. Unfortunately, there is significant variability in reported prevalence rates. Heterogeneity in measurement tools potentially contribute to this. Inclusion criteria: Studies were eligible if they (a) reported mental health outcomes of adult patients diagnosed with COVID-19 and admitted to an ICU, (b) used standardised mental health outcome measures, and (3) were peer-reviewed. Methods: Searches were conducted in PubMed, PsycInfo, and Scopus. The initial search retrieved 1234 publications. After de-duplication and title and abstract screening, 72 full-text articles were examined for eligibility and 44 articles were excluded, leaving 28 eligible studies. Reference lists of the eligible studies were screened, and four other studies were added. 32 studies were ultimately included in this review. Results: Significant heterogeneity of measurement tools and clinical thresholds were observed. Only 6.25% of the studies compared changes in mental health outcomes to baseline measurements. Between five and nine unique measurement tools were used to study depression, anxiety, and PTSD, respectively. Studies were also observed to use up to 19 different thresholds to establish the prevalence of PTSD. Conclusions: The heterogeneity of measurement tools and thresholds continues to confound prevalence rate estimations of mental health complications post-ICU admission. Future research will benefit from consistency in the use of recommended outcome measures and the use of psychometrically comparable cut-off points between key measures.

RESUMO

BACKGROUND: The present systematic review aimed to synthesize the results of meta-analyses which examine the effects of digital mental health interventions (DMHIs) on post-traumatic stress disorder (PTSD) symptoms, and investigate whether intervention characteristics (i.e., technique, timeframe, and therapeutic guidance) and methodological characteristics including outcome measures and sample inclusion criteria (age, gender, socioeconomic status, country, comorbidity) moderate the efficacy of digital interventions. METHODS: A systematic search of various sources (ECSCOhost PsycInfo, PubMed, Web of Science, Scopus, EBSCOhost ERIC, Google Scholar, ProQuest Dissertations & Theses) including five peer-reviewed journals was conducted to identify relevant meta-analyses up to December 2023, and 11 meta-analyses were included in the final review. RESULTS: Overall, our review elucidates that DMHIs are appropriate for alleviating PTSD symptoms in adults, with more consistent evidence supporting the efficacy of cognitive behavioral therapy (CBT)-based, compared to non-CBT-based, interventions when compared to control conditions. However, we found inconclusive evidence that the efficacy of DMHIs varied according to intervention timeframe, therapeutic guidance, or sample characteristics. LIMITATIONS: A relatively limited number of different populations was sampled across meta-analyses. Further, while our review focused on PTSD symptoms to indicate the efficacy of digital interventions, other indices of effectiveness were not examined. CONCLUSION: Our findings indicate the clinical utility of DMHIs for managing PTSD symptoms particularly when CBT-based intervention techniques are employed.

RESUMO

OBJECTIVES: The current study aimed to investigate the health implications of negative work-to-family spillover on cardiovascular risk biomarkers. METHODS: In a large-scale cross-sectional dataset of working or self-employed midlife and older adults in the United States (N = 1179), we examined five biomarkers linked to cardiovascular risk, including high-density lipoprotein (HDL) cholesterol, low-density lipoprotein cholesterol, triglyceride, interleukin-6, and C-reactive protein. Negative work-to-family spillover, measured using a four-item self-reported questionnaire, was included into our model to study its association with these cardiovascular risk biomarkers. RESULTS: Our findings indicate a significant association between negative work-to-family spillover and cardiovascular risk biomarkers - higher triglycerides (ß = 0.108, p < .001), interleukin-6 (ß = 0.065, p = .026), and C-reactive protein (ß = 0.067, p = .022), and lower HDL cholesterol (ß = -0.104, p < .001). The associations on triglycerides (ß = 0.094, p = .001) and HDL cholesterol (ß = -0.098, p < .001) remained significant even after controlling numerous control variables of demographics, medication, health-status, and health-related behaviors. The findings were also consistent against slight variations in the analytic method and adjustment for multiple comparisons. CONCLUSIONS: The current study supports the premise that spillover of work-related tensions into family life is associated with objective physiological changes that contribute to cardiovascular risk.

RESUMO

The congruency sequence effect (CSE) is one of the most investigated effects in the cognitive control literature. The conflict monitoring theory suggests that the CSE is the result of adjustments in cognitive control based on perceived conflict. A recent paper by Zhang and colleagues, has investigated whether the manipulation of conflict level by changing distractor incompatibility in a flanker task affects the amount of adjustments in cognitive control. Their study produced mixed findings, somewhat supporting the original conflict monitoring theory, but also suggesting other explanations, such as the repetition expectancy account. We replicated the experimental design in a multisite online study (N = 347), with Hungarian, Italian, and Singaporean participants. Our results supported the prediction that changes in the level of conflict trigger conflict adaptation, revealing that increasing conflict levels induced stronger adaptive control. Bayesian hypothesis testing indicated a monotonic reduction in congruency effects as a function of previous conflict strength. This finding is in line with the extension of the traditional conflict monitoring theory, as well as other theories like affective signaling and expected value of control, implying that the relationship between conflict and interference effects is gradual, rather than a binary function.

RESUMO

When someone violates a social norm, others may think that some sanction would be appropriate. We examine how the experience of emotions like anger and disgust relate to the judged appropriateness of sanctions, in a pre-registered analysis of data from a large-scale study in 56 societies. Across the world, we find that individuals who experience anger and disgust over a norm violation are more likely to endorse confrontation, ostracism and, to a smaller extent, gossip. Moreover, we find that the experience of anger is consistently the strongest predictor of judgments of confrontation, compared to other emotions. Although the link between state-based emotions and judgments may seem universal, its strength varies across countries. Aligned with theoretical predictions, this link is stronger in societies, and among individuals, that place higher value on individual autonomy. Thus, autonomy values may increase the role that emotions play in guiding judgments of social sanctions.

RESUMO

While borderline personality disorder (BPD) symptomatology has been studied extensively in clinical populations, the mechanisms underlying its manifestation in nonclinical populations remain largely understudied. One aspect of BPD symptomatology in nonclinical populations that has not been well studied is cognitive mechanisms, especially in relation to executive functions. To explore the cognitive mechanisms underlying BPD symptomatology in nonclinical populations, we analysed a large-scale dataset of 233 young adults that were administered with nine executive function tasks and BPD symptomatology assessments. Our structural equation modelling did not find any significant relations between latent factors of executive functions and the severity of BPD symptomatology. Contrary to our hypothesis, our result suggests that deficits in executive functions were not a risk factor for BPD symptomatology in the nonclinical young adult sample.

RESUMO

Research on self-esteem reactivity has demonstrated that self-esteem fluctuates in response to daily stressor exposure, and the strength of this relationship varies between individuals. Drawing upon the positive link between objective socioeconomic status (SES) and self-esteem, how subjective SES influences self-esteem reactivity to daily stressor exposure was explored. Using a 7-day daily diary study, the current study (Nparticipants = 243, Ndays = 1651) adopted a multilevel analysis to demonstrate that subjective SES attenuated the within-person association between daily stressor exposure and daily self-esteem, even after controlling for demographics and objective indicators of SES. The interactions were also consistent across social stressors and non-social stressors. The findings provide evidence supporting the protective role of subjective SES in self-esteem reactivity to daily stressor exposure.

RESUMO

While smartphones have brought many benefits and conveniences to users, there is continuing debate regarding their potential negative consequences on everyday cognition such as daily cognitive failures. A few cross-sectional studies have found positive associations between smartphone use and cognitive failures. However, several research gaps remain, such as the use of cross-sectional designs, confounds related to stable individual differences, the lack of validity in self-report measures of smartphone use, memory biases in retrospective self-reports, and the lack of differentiation between smartphone checking and smartphone screen time. To simultaneously address the aforementioned shortcomings, the current study examined the within-person associations between various objective indicators of smartphone use and daily cognitive failures using a 7-day daily diary study. Multilevel modelling revealed that smartphone checking, but not total smartphone screen time, predicted a greater occurrence of daily cognitive failures at the within-person level. Surprisingly, we also found negative within-person associations between smartphone screen time for social- and tools-related applications and daily cognitive failures, suggesting that some types of smartphone use may temporarily benefit one's cognitive functioning. This finding demonstrates the importance of studying the specific functions of smartphone use and their differential cognitive consequences, as well as highlights the complex relations between smartphone use and cognition.

RESUMO

Existing studies have shown that direct exposure to a real nature environment has a restorative effect on attentional resources after a mentally fatiguing task. However, it remains unclear whether virtual nature simulations can serve as a substitute for real nature experienced in the outdoors to restore executive attention. Given the mixed findings in the literature, the present study sought to examine if viewing videos with natural scenery (vs. a control with urban scenery) restores participants' working memory capacity - measured by an operation span task - in a high-powered pre-registered within-subject experimental study. Overall, our within-subject experiment did not find any evidence to support the benefit of watching videos with natural scenery on restoration of executive attention. Moreover, the results from our Bayesian analyses further showed substantial support for the null hypothesis. Our study suggests that virtual nature simulations, even with the use of videos, may not be able to replicate the experiences of nature in the outdoors and restore attentional resources.

RESUMO

The negative consequences of smartphone usage have seen frequent discourse in popular media. While existing studies seek to resolve these debates in relation to executive functions, findings are still limited and mixed. This is partly due to the lack of conceptual clarity about smartphone usage, the use of self-reported measures, and problems related to task impurity. Addressing these limitations, the current study utilizes a latent variable approach to examine various types of smartphone usage, including objectively measured data-logged screen time and screen-checking, and nine executive function tasks in 260 young adults through a multi-session study. Our structural equation models showed no evidence that self-reported normative smartphone usage, objective screen time, and objective screen-checking are associated with deficits in latent factors of inhibitory control, task-switching, and working memory capacity. Only self-reported problematic smartphone usage was associated with deficits in latent factor task-switching. These findings shed light on the boundary conditions of the link between smartphone usage and executive functions and suggest that smartphone usage in moderation may not have inherent harms on cognitive functions.

RESUMO

Despite the well-documented negative effects of anxiety on task-switching (switch costs), few studies have directly tested major theoretical assumptions about (a) the specific processing component of task-switching that is impaired by anxiety, (b) anxious individuals' strategies during task-switching, and (c) the mediating role of mind wandering in the relation between anxiety and task-switching. We addressed these issues using a stochastic diffusion model analysis and novel thought-probe technique in the task-switching paradigm. Our results suggest that the locus of impaired switch costs under state anxiety lies in the efficiency of task-set reconfiguration and not in proactive interference processing. Moreover, state anxiety was associated with impaired mixing costs, which are another crucial index of task-switching. We found only partial evidence for anxious individuals' proneness to compensatory strategies during task-switching. However, no evidence was found for a mediating role of task-unrelated thoughts and a moderating role of working memory in the relation between anxiety and task-switching. Our findings elucidate theoretical assumptions underlying anxiety and cognitive functioning. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
