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. …


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

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

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 …


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

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 …


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

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 …
