As smartphones have become portable and immersive devices that afford social, informational, and recreational conveniences unbounded by physical restrictions, most daily activities have become closely intertwined with the presence of smartphones. This constant presence of smartphones in daily activities, however, may be concerning as some studies have suggested that smartphones—even their mere presence—can be distracting and can impair cognitive outcomes. However, such findings have not been consistently observed. To reconcile mixed findings, the current meta-analysis synthesized 166 effect sizes drawn from 53 samples and 33 studies including 4,368 participants on the effect of mere presence of smartphone on cognitive functions. …

Intensive mindfulness practices have been shown to improve cognitive abilities such as executive functions. However, most of these mindfulness-based practices require the participants to be involved either an extended immersive experience or repeated daily practice that may span over multiple weeks or months. Extending from the promising effect of intensive mindfulness training, recent studies have also suggested that a single session of brief mindfulness training is sufficient to temporarily enhance cognitive functions. However, the positive effect of brief mindfulness was not always consistent. In view of the inconsistent findings, the current study aims to critically examine the effectiveness of a …


Relationship Between Contentment And Working Memory Capacity: Experimental And Naturalistic Evidence, Khai Qing Chua, Rachel Ng, Clarissa L. Q. Sung, Andree Hartanto, Vincent Y. S. Oh, Eddie M. W. Tong Oct 2023

Relationship Between Contentment And Working Memory Capacity: Experimental And Naturalistic Evidence, Khai Qing Chua, Rachel Ng, Clarissa L. Q. Sung, Andree Hartanto, Vincent Y. S. Oh, Eddie M. W. Tong

Research Collection School of Social Sciences

Contentment is a positive emotion characterized by perceived goal attainment, a sense of having or being enough, and a focus on the present. Research on this new construct is thin, and no studies have examined its cognitive properties, particularly whether it facilitates or impairs controlled cognitive processes. We hypothesize that contentment positively predicts working memory. We found support for this hypothesis in two experimental studies (Studies 1 and 2) which showed that induced contentment improved working memory in the operation span task, and in one non-experimental study (Study 3) which showed that measured contentment positively correlated with working memory on …


Problematic Smartphone Usage, Objective Smartphone Engagement, And Executive Functions: A Latent Variable Analysis, Andree Hartanto, Yi Jing Chua, Frosch Yi Xuan Quek, Joax Wong, Wei Ming Ooi May 2023

Problematic Smartphone Usage, Objective Smartphone Engagement, And Executive Functions: A Latent Variable Analysis, Andree Hartanto, Yi Jing Chua, Frosch Yi Xuan Quek, Joax Wong, Wei Ming Ooi

Research Collection School of Social Sciences

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 …


Do Executive Functions Buffer Against Covid-19 Fear And Stress? A Latent Variable Approach, Tina Li Yi Ng, Nadyanna M. Majeed, Verity Yu Qing Lua, Andree Hartanto May 2023

Do Executive Functions Buffer Against Covid-19 Fear And Stress? A Latent Variable Approach, Tina Li Yi Ng, Nadyanna M. Majeed, Verity Yu Qing Lua, Andree Hartanto

Research Collection School of Social Sciences

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 …


Anxiety Disorders And Executive Functions: A Three-Level Meta-Analysis Of Reaction Time And Accuracy, Nadyanna M. Majeed, Yi Jing Chua, Meenakshi Kothari, Manmeet Kaur, Frosch Y. X. Quek, Matthew H. S. Ng, Wee Qin Ng, Andree Hartanto Feb 2023

Anxiety disorders, one of the most common classes of psychological disorders, have been shown to result in a decreased quality of life. Although some research suggests that anxiety disorders are linked to impairments in executive functioning, the inconsistency in the current literature yields an unclear conclusion on the relationship between the two. The current meta-analysis systematically investigated 55 records (N = 4601; kReactionTime = 44, kAccuracy = 79) that compared various groups with anxiety disorders to healthy controls on executive function tasks. Overall, our meta-analysis showed that individuals with anxiety disorders exhibited significant deficits in performance efficiency (reaction times) on …


Executive Functions Predict The Trajectories Of Rumination In Middle-Aged And Older Adults: A Latent Growth Curve Analysis, Gilaine Rui Ng, Wee Qin Ng, Hwajin Yang Jan 2023

Executive Functions Predict The Trajectories Of Rumination In Middle-Aged And Older Adults: A Latent Growth Curve Analysis, Gilaine Rui Ng, Wee Qin Ng, Hwajin Yang

Research Collection School of Social Sciences

Previous studies suggest that executive functions (EF)—a set of domain-general cognitive control processes that contribute to the regulation of emotion—are generally associated with ruminative tendencies. However, there is a dearth of research that examines how EF influences changes in rumination over time, especially in middle-aged and older adults who typically experience a decline in EF. To fill this gap in the literature, we analyzed a large-scale combined dataset from the MIDUS Refresher, Daily Diary, and Cognitive Projects. We examined the impact of EF on the trajectory of rumination across 8 days using latent growth curve analysis. We also examined age …


Executive Function Deficits And Borderline Personality Disorder Symptomatology In A Nonclinical Adult Sample: A Latent Variable Analysis, Keisha Divya Veerapandian, Gabriel X. D. Tan, Nadyanna M. Majeed, Andree Hartanto Jan 2023

Executive Function Deficits And Borderline Personality Disorder Symptomatology In A Nonclinical Adult Sample: A Latent Variable Analysis, Keisha Divya Veerapandian, Gabriel X. D. Tan, Nadyanna M. Majeed, Andree Hartanto

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 …


The Influence Of Subjective Socioeconomic Status On Executive Functions In Middle-Aged And Older Adults, Yu Ping Wong, Hwajin Yang Mar 2022

The Influence Of Subjective Socioeconomic Status On Executive Functions In Middle-Aged And Older Adults, Yu Ping Wong, Hwajin Yang

Research Collection School of Social Sciences

Subjective socioeconomic status (SES) has been shown to influence both psychological and biological outcomes. However, less is known about whether its influence extends to cognitive outcomes. We examined the relation between subjective SES and executive functions (EF)—a set of cognitive control processes—and its underlying mechanisms. By analyzing a nationally representative cohort of middle-aged and older adults (age 40–80) from the MIDUS 2 National Survey and Cognitive Project, we tested a serial mediation model with sense of control and health as sequential mediators. Using structural equation modeling, we found that subjective SES is indirectly related to EF via sense of control …


Social Media Use Improves Executive Functions In Middle-Aged And Older Adults: A Structural Equation Modeling Analysis, Shi Ann Shuna Khoo, Hwajin Yang Oct 2020

Social Media Use Improves Executive Functions In Middle-Aged And Older Adults: A Structural Equation Modeling Analysis, Shi Ann Shuna Khoo, Hwajin Yang

Research Collection School of Social Sciences

Given the paucity of research on the cognitive implications of social media use in middle and late adulthood, we sought to understand the relations between middle-aged and older adults' social media use and their executive functions (EF)—a set of domain-general cognitive control processes—and the underlying mechanism. By analyzing a nationally representative cohort ranging from ages 40s–70s from the MIDUS Refresher Survey and Cognitive Project, we tested a serial mediation model with perception of social support and sense of control (i.e., personal mastery and perceived constraints) as sequential mediators in a structural equation modeling analysis. We found that perceived social support …


Cognitive, Social, Emotional, And Subjective Health Benefits Of Computer Use In Adults: A 9-Year Longitudinal Study From The Midlife In The United States (Midus), Andree Hartanto, Jose C. Yong, Wei Xing (Zhuo Weixing) Toh, Sean Teck Hao Lee, Yue Qi Germaine Tng, William Tov Mar 2020

Cognitive, Social, Emotional, And Subjective Health Benefits Of Computer Use In Adults: A 9-Year Longitudinal Study From The Midlife In The United States (Midus), Andree Hartanto, Jose C. Yong, Wei Xing (Zhuo Weixing) Toh, Sean Teck Hao Lee, Yue Qi Germaine Tng, William Tov

Research Collection School of Social Sciences

Computer use has been proposed to carry a host of benefits for cognitive function and socioemotional well-beingin older adults. However, the literature on computer use remains equivocal as extant research suffers from mixedfindings as well as methodological limitations, such as overreliance on cross-sectional designs, small samplesizes, and use of narrow criterions. The current studies (NStudy 1 ¼ 3,294, NStudy 2 ¼ 2,683) sought to address theselimitations through the use of a large-scale, nationally representative, and longitudinal dataset. We found thatfrequency of computer use—over a period of approximately 9 years—longitudinally predicted positive changesin executive functioning, hedonic well-being, eudaimonic well-being, sense of …


The Role Of Bilingual Interactional Contexts In Predicting Interindividual Variability In Executive Functions: A Latent Variable Analysis, Andree Hartanto, Hwajin Yang Sep 2019

The Role Of Bilingual Interactional Contexts In Predicting Interindividual Variability In Executive Functions: A Latent Variable Analysis, Andree Hartanto, Hwajin Yang

Research Collection School of Social Sciences

Despite a growing number of studies on bilingual advantages in executive functions (EF), their findings have been inconsistent. To shed light on this issue, we aimed to address both the conceptual and methodological limitations that have prevailed in the literature: failure to consider diverse bilingual experiences when assessing bilingual advantages or to address the task impurity problems that can arise with EF tasks. Drawing on the adaptive control hypothesis and control process model of code-switching, we adopted theory-driven and latent variable approaches to examine the relations between bilingual interactional contexts and EF. By administering 9 EF tasks to 175 bilingual …


Measurement Matters: Higher Waist-To-Hip Ratio But Not Body Mass Index Is Associated With Deficits In Executive Functions And Episodic Memory, Andree Hartanto, Jose C. Yong Sep 2018

Measurement Matters: Higher Waist-To-Hip Ratio But Not Body Mass Index Is Associated With Deficits In Executive Functions And Episodic Memory, Andree Hartanto, Jose C. Yong

Research Collection School of Social Sciences

Background: The current study aimed to reconcile the inconsistentfindings between obesity, executive functions, and episodic memory byaddressing major limitations of previous studies, including overreliance onbody mass index (BMI), small sample sizes, and failure to control forconfounds.Methods: Participants consisted of 3,712 midlife adults from theCognitive Project of the National Survey of Midlife Development. Executivefunctions and episodic memory were measured by a battery of cognitive functiontests.Results: We found that higher waist-to-hip ratio was associated withdeficits in both executive functions and episodic memory, above and beyond theinfluence of demographics, comorbid health issues, health behaviors,personality traits, and self-perceived obesity. However, higher BMI was notassociated …

We integrate life history (LH) theory with “hot/cool” systems theory of self-regulation to predict sexually and socially coercive behaviors, including intimate partner violence (IPV) and interpersonal aggression (IPA). LH theory predicts that a variety of traits form LH strategies: adaptively coordinated behavioral clusters arrayed on a continuum from slow to fast. We test structural models examining 2 propositions: (a) “hot” cognitive processes, promoted by faster LH strategies, increase the likelihood of sexually/socially coercive behaviors that make up IPV and IPA; (b) “cool” cognitive processes, promoted by slower LH strategies, buffer against the likelihood of sexually/socially coercive behaviors that make up …


Is The Smartphone A Smart Choice? The Effect Of Smartphone Separation On Executive Functions, Andree Hartanto, Hwajin Yang Nov 2016

Is The Smartphone A Smart Choice? The Effect Of Smartphone Separation On Executive Functions, Andree Hartanto, Hwajin Yang

Research Collection School of Social Sciences

Despite a huge spike in smartphone overuse, the cognitive and emotional consequences of smartphone overuse have rarely been examined empirically. In two studies, we investigated whether separation from a smartphone influences state anxiety and impairs higher-order cognitive processes, such as executive functions. We found that smartphone separation causes heightened anxiety, which in turn mediates the adverse effect of smartphone separation on all core aspects of executive functions, including shifting (Experiment 1) and inhibitory control and working-memory capacity (Experiment 2). Interestingly, impaired mental shifting was evident regardless of the extent of smartphone addiction, whereas smartphone addiction significantly moderated the negative effect …


Age Matters: The Effect Of Onset Age Of Video Game Play On Task-Switching Abilities, Andree Hartanto, Wei Xing Toh, Hwajin Yang May 2016

Age Matters: The Effect Of Onset Age Of Video Game Play On Task-Switching Abilities, Andree Hartanto, Wei Xing Toh, Hwajin Yang

Research Collection School of Social Sciences

Although prior research suggests that playing video games can improve cognitive abilities, recent empirical studies cast doubt on such findings (Unsworth et al., 2015). To reconcile these inconsistent findings, we focused on the link between video games and task switching. Furthermore, we conceptualized video-game expertise as the onset age of active video-game play rather than the frequency of recent gameplay, as it captures both how long a person has played video games and whether the individual began playing during periods of high cognitive plasticity. We found that the age of active onset better predicted switch and mixing costs than did …


The Importance Of Bilingual Experience In Assessing Bilingual Advantages In Executive Functions, Hwajin Yang, Andree Hartanto, Sujin Yang Feb 2016

The Importance Of Bilingual Experience In Assessing Bilingual Advantages In Executive Functions, Hwajin Yang, Andree Hartanto, Sujin Yang

Research Collection School of Social Sciences

Paap, Johnson, and Sawi (2015) contend that bilingual advantages in executive functions (EF) do not exist, and that there is no compelling evidence that a certain bilingual experience hones a specific component of EF (p. 272). We believe that this conclusion is premature, because Paap et al.'s approach was not sufficiently refined to effectively capture the real-world complexity of bilingualism. In this commentary, we draw on the adaptive control hypothesis (Green & Abutalebi, 2013) and argue that studies of bilingualism should consider specific bilingual experiences that potentially moderate bilingual advantages through substantial demand for language control (for similar commentaries, see …
