The mechanism of inhibition control in mathematical reasoning: a functional near-infrared spectroscopy study.

BACKGROUND AND OBJECTIVES: The ability to comprehend and engage in mathematical reasoning is a fundamental cognitive skill, central to problem-solving and critical thinking. However, the intricate cognitive processes underlying mathematical reasoning, particularly in relation to inhibitory control, have garnered increasing attention in recent research. While previous studies have explored this connection, there remains a need for a more comprehensive understanding of the interplay between inhibitory control and mathematical reasoning. This study explored the contribution of response inhibition and semantic inhibition to scientific reasoning by comparing the brain activation of the speeded-reasoning task of mathematical subdomain concepts with that of the Go/Nogo and Stroop tasks. METHOD: Using functional near-infrared spectroscopy, oxygenated hemoglobin (oxy-Hb) was recorded in 28 subjects performing Go/Nogo tasks, Stroop tasks and speeded-reasoning tasks. The study was divided into two parts. In one part, subjects performed the Go/Nogo task and the Stroop task, and in the other part, subjects performed speeded-reasoning tasks. RESULTS: The results showed that the subjects had slower responses and lower accuracy when judging incongruent statements. The concentration of oxy-Hb in the brain region related to inhibition was increased. In addition, the oxy-Hb in reasoning incongruent nonmathematical statements was correlated to the Go/Nogo task, whereas the oxy-Hb in reasoning incongruent mathematical statements was correlated to the Stroop task. CONCLUSION: This result supports the hypothesis that inhibitory control plays a role in the scientific reasoning of mathematical subdomain concepts, and both response inhibition and semantic inhibition are involved in suppressing the interference of mathematical misconceptions.Supplementary Video Abstract, Supplemental digital content 1, http://links.lww.com/WNR/A732.

Neural Mechanisms of Inhibition in Scientific Reasoning: Insights from fNIRS.

This study examines the impact of response and semantic inhibition on scientific reasoning using fNIRS data from 30 students (15 male, 15 female). Utilizing Go/Nogo and Stroop-like tasks within a modified speeded-reasoning task, it was found that inhibition significantly influences scientific reasoning. Specifically, slower responses and lower accuracy on incongruent statements were linked to increased activity in bilateral dorsolateral prefrontal cortex (DLPFC) and pre-supplementary motor area (pre-SMA). The research shows that both DLPFC and pre-SMA are associated with overcoming misconceptions in scientific reasoning. The findings suggest that understanding inhibitory mechanisms can enhance educational strategies to improve critical thinking and scientific literacy.

Hypnobirthing Training for First-Time Mothers: Pain, Anxiety and Postpartum Wellbeing.

Purpose: Childbirth represents a significant life event, bringing about both physical and emotional transformations in a woman's life. Among other psychological aspects associated with childbirth, labor pain, death anxiety, and postpartum depression have garnered significant attention in the field of maternal and reproductive health. This study is intended to evaluate how the effectiveness of hypnobirthing training alleviates labor pain, mitigates death anxiety enhances postpartum well-being reduces labor hours, and how anxiety exacerbates the duration of labor. Methods: Data were collected from (N = 50) young and middle-aged postpartum women in the outpatient obstetrics and gynecology departments of the Civil Hospital, Waseer Gynecology Hospital and Basic Health Unit Jalal Ballagan in Gujranwala, Pakistan, by using the convenience sampling technique. Out of 50, women were divided into a control (N = 25) and an experimental group (N = 25). They were recruited during their 33 weeks of pregnancy until childbirth for hypnobirthing training. Numerical Pain Rating Scale (NPRS), Templer Death Anxiety Scale (TDAS), and Edinburgh Postnatal Depression Scale (EPDS) were used to collect participants' responses. Results: Findings proved hypnobirthing training as a catalyst in significantly reducing labor pain, death anxiety, and postpartum depression. Furthermore, the analysis indicated that death anxiety exacerbates the labor duration hours and hypnobirthing decreases the labor hours in the experimental group of women. Conclusion: It sheds light on the effectiveness of hypnobirthing training to enhance the birthing process. Findings underscore the significance of collaboration between obstetricians, psychologists, and mental health professionals to develop integrated care plans that address both physical and psychological aspects of childbirth.

Postpartum Depression and Health: Role of Perceived Social Support among Pakistani Women.

Postpartum depression (PPD) can predispose to physical and mental health problems in Pakistani women. However, PPD is associated with health and perceived social support, yet their causal relationship is unclear. Therefore, this study intended to evaluate the association of PPD with insomnia, mental health, and physical health. The convenience sampling technique was used to collect data from 320 (52.8%) young and middle-aged postpartum women, at the outpatient departments of obstetrics and gynecology of the Government Maula Bakhsh Hospital, District Head Quarter in Sargodha, Pakistan. The Edinburgh Postnatal Depression Scale, Pittsburgh Sleep Quality Index, Warwick-Edinburgh Mental Well-being Scale, patient health questionnaire, and Multidimensional Scale of Perceived Social Support were used to measure study variables. The results revealed a significant positive relationship between PPD and physical health (r = 0.45, p = 0.001), negative relationships with insomnia (r = -0.24, p < 0.001), and perceived social support (r = -0.38, p = 0.001). Results further confirmed that perceived social support played a moderating role (ß = 0.97, p = 0.01) in the relationship between PPD and mental health among Pakistani women. This study concluded that perceived social support has an important role in PPD and the health of Pakistani women. The study also concluded that poor health is a risk indicator for the identification of aid in the early stages of postpartum among Pakistani women.

Pre- and Post-Pandemic (COVID-19) Mental Health of International Students: Data from a Longitudinal Study.

Purpose: International students are highly vulnerable to the risk of mental health worsening before and during the pandemic (COVID-19). This study investigated international students' mental health pre- and post-pandemic (COVID-19). Methods: It is a longitudinal study, and data were collected online, pre-pandemic (N = 470) and during the pandemic (N = 420). Using a random sampling technique, a self-administered questionnaire was used to measure mental health, including depression and anxiety. Results: Findings show that international students' mental health was good in pre-pandemic. Meanwhile, international students were found to be more depressed and anxious during the pandemic. Findings also investigated that in the pre-pandemic phase, young students' and mainly females' mental health was worsened. Conclusion: This study concluded that students' mental problems are alarming, so the university should provide psychological services for the student's mental health. Post-pandemic is leaving long-lasting psychological effects and will require further investigation.

Stigmatization, panic disorder, and death anxiety among patients of Covid-19: Fourth wave of pandemic in Pakistan.

BACKGROUND: In Pakistan, the fourth wave of COVID-19 is causing an increasing number of positive cases. This fourth wave may be a risky aspect of mental health issues for COVID-19 patients. This quantitative study is designed to understand the stigmatization, and panic disorder and to explore the mediating role of death anxiety among patients of COVID-19 during the fourth wave of novel coronavirus. METHODS: The study was conducted using a correlational research design. The survey was carried out by utilizing a questionnaire with a convenient sample technique. The sample of the study was comprised of 139 patients with COVID-19. Data were collected through Stigma Scale for Chronic Illnesses (SSCI), The Panic Disorder Severity Scale (PDSS), and Death Anxiety Inventory. RESULTS: Results show that stigma is significantly positively related to panic disorder and death anxiety. Furthermore, panic disorder is also significantly positively related to death anxiety. Results also indicate that stigmatization is a significant positive predictor for death anxiety and panic disorder. Moreover, results indicate that death anxiety has a mediating role in the relationship between stigmatization and panic disorder with age and gender as covariates. CONCLUSION: This study would be helpful for people around the world to understand this threatening contagious virus so they wouldn't stigmatize infected ones. Additional research is required for the sustainable improvement of anxiety over time.

A Mediation Moderation Model between Self-Evaluative Emotions and Relapse Rate among Polysubstance Users: A Comparative Cross-Sectional Study.

A substantial portion of drug abuse research has concentrated on people with a single-substance-use disorder (SSUD), but many people abuse more than one drug. Studies have yet to examine how those with polysubstance-use disorder (PSUD) differ from those with an SSUD on the risk of relapse, self-evaluative emotions (e.g., shame and guilt), and personality factors (e.g., self-efficacy). Eleven rehab facilities in Lahore city, Pakistan were randomly chosen to provide a sample of 402 males with PSUD. For comparison, 410 age-matched males with SSUD were enlisted using a demographic form with eight questions, the State Shame and Guilt Scale, and the General Self-Efficacy Scale. Mediated moderation analysis was performed using Hayes' process macro. The results demonstrate that shame-proneness is positively associated with relapse rate. Guilt-proneness mediates the relationship between shame-proneness and relapse rate. Self-efficacy buffers the influence of shame-proneness on relapse rate. Although the mediation and moderation effects were found in both study groups, these effects were significantly stronger among people with PSUD than those with SSUD. To be more specific, people with PSUD reported a higher overall score on shame, guilt, and relapse rate. Additionally, people with SSUD indicated a higher score on self-efficacy than those with PSUD. The findings of this study suggest that drug rehab facilities should implement a variety of strategies to raise drug users' levels of self-efficacy, which will help to reduce their risk of relapse.
