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

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 …


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 …
