    High School and University Students' Reasoning About Decision-Making Autonomy and Parental Authority Legitimacy in Child–Mother Conflicts
    (WILEY, 2025-05-02) Kuyel, N.; Acar, M.
    This study investigated youths' reasoning about personal autonomy and maternal authority in hypothetical emerging adult child–mother conflicts in Türkiye. High school and university students (N = 138, Mage = 19.72 years) from secular and religious schools completed a self-report questionnaire including eight conflict scenarios where the mother opposes her child's decision to marry a non-Muslim or get a tattoo. Maternal opposition in hypothetical scenarios was presented in the forms of maternal advice and maternal use of haram opposition. Haram opposition implies the declaration of maternal accrued rights (a concept deeply rooted in Turkish culture) as haram. The results showed that participants were more likely to subordinate child autonomy to maternal authority when the mother in hypothetical scenarios was depicted as using haram opposition. Authoritative parenting appeared to strengthen this effect. This study has shown that haram opposition is a psychological control mechanism to subordinate child autonomy to maternal authority. © 2025 British Psychological Society.

    Unraveling Neural Pathways of Political Engagement: Bridging Neuromarketing and Political Science for Understanding Voter Behavior and Political Leader Perception
    (Frontiers Media SA, 2023-12-21) Çakar, Tuna; Filiz, Gözde
    Political neuromarketing is an interdisciplinary field that combines marketing, neuroscience, and psychology to understand voter behavior and political leader perception. This interdisciplinary field offers novel techniques to understand complex phenomena such as voter engagement, political leadership, and party branding. This study aims to understand the neural activation patterns of voters when they are exposed to political leaders using functional near-infrared spectroscopy (fNIRS) and machine learning methods. We recruited participants and recorded their brain activity using fNIRS when they were exposed to images of different political leaders. This neuroimaging method (fNIRS) reveals brain regions central to brand perception, including the dorsolateral prefrontal cortex (dlPFC), the dorsomedial prefrontal cortex (dmPFC), and the ventromedial prefrontal cortex (vmPFC). Machine learning methods were used to predict the participants' perceptions of leaders based on their brain activity. The study has identified the brain regions that are involved in processing political stimuli and making judgments about political leaders. Within this study, the best-performing machine learning model, LightGBM, achieved a highest accuracy score of 0.78, underscoring its efficacy in predicting voters' perceptions of political leaders based on the brain activity of the former. The findings from this study provide new insights into the neural basis of political decision-making and the development of effective political marketing campaigns while bridging neuromarketing, political science and machine learning, in turn enabling predictive insights into voter preferences and behavior

    Social Connectedness and Mental Health Before and During the Covid-19 Pandemic in a Community Sample in Korea
    (Public Library of Science, 2023-10-19) You, Sungeun; Moon, Hyejoo; Lee, Sojung; Şahin, Banu Çankaya; Caine, Eric; Ko, Jisu; Cankaya, Banu
    This study compared social connectedness patterns and examined the relationships between objective or subjective social connectedness and mental health before and during the COVID-19 pandemic among community dwelling adults in South Korea. An identical online survey was administered at two time points, in 2019 prior to the onset and again in 2021. Objective (network diversity and network size) and subjective (thwarted belongingness and perceived burdensomeness) social connectedness were measured along with positive and negative indices of mental health (depression, suicidal behavior, happiness, and life satisfaction). The results indicated that among social connectedness indices perceived burdensomeness were significantly higher during the COVID-19 pandemic compared to the prior period, while network size was smaller. Subjective social connectedness was associated with all aspects of mental health consequences, either positive or negative. Among objective social connectedness, only network diversity was significantly associated with increased happiness and life satisfaction, and objective social connectedness was not associated with depression and suicidal behavior. These associations did not differ across the two time periods. The findings, both before and during the pandemic, indicated that network diversity is an important factor for positive indices of mental health and that efforts to increase subjective social connectedness are needed to decrease the risk of depression and suicidal behavior.

    A Longitudinal Assessment of Variability in Covid-19 Vaccine Hesitancy and Psychosocial Correlates in a National United States Sample
    (Elsevier Sci Ltd, 2023-02-01) Shook, Natalie J.; Oosterhoff, Benjamin; Sevi, Barış
    Recent evidence suggests that COVID-19 vaccine hesitancy is not static. In order to develop effective vaccine uptake interventions, we need to understand the extent to which vaccine hesitancy fluctuates and identify factors associated with both between- and within-person differences in vaccine hesitancy. The goals of the current study were to assess the extent to which COVID-19 vaccine hesitancy varied at an individual level across time and to determine whether disgust sensitivity and germ aversion were associated with between- and within-person differences in COVID-19 vaccine hesitancy. A national sample of U.S. adults (N = 1025; 516 woman; M-age = 46.34 years, SDage = 16.56, range: 18 to 85 years; 72.6 % White) completed six weekly online surveys (March 20 - May 3, 2020). Between-person mean COVID-19 vaccine hesitancy rates were relatively stable across the six-week period (range: 38-42 %). However, there was considerable within-person variability in COVID-19 vaccine hesitancy. Approximately, 40 % of the sample changed their vaccine hesitancy at least once during the six weeks. There was a significant between-person effect for disgust sensitivity, such that greater disgust sensitivity was associated with a lower likelihood of COVID-19 vaccine hesitance. There was also a significant within-person effect for germ aversion. Participants who experienced greater germ aversion for a given week relative to their own six week average were less likely to be COVID-19 vaccine hesitant that week relative to their own six-week average. This study provides important information on rapidly changing individual variability in COVID-19 vaccine hesitancy on a weekly basis, which should be taken into consideration with any efforts to decrease vaccine hesitancy and increase vaccine uptake. Further, these findings identify-two psychological factors (disgust sensitivity and germ aversion) with malleable components that could be leveraged in developing vaccine uptake interventions.

    But the Poor Needed It More: Children's Judgments on Procedural Justice To Allocate Resources Between Two Candidates Equal in Merit, Different in Need
    (Elsevier Science Inc, 2023-08-01) Sıvış, Özce; Acar, Melike
    The current study investigated children's judgments on procedural justice and its outcomes when the candidates were equal in merit but different in need. A total of 88 children (41 girls and 47 boys) aged 7 to 11 years were individually interviewed (Mage = 8 years 9 months, SD = 14.065 months). Results showed that, regardless of age, children tended to give educational resources to the resource-poor candidates. However, children's welfare considera-tion of the resource-poor candidates increased with age. Children also made differentiated judgments based on the resource type and treated educational materials as more necessary than educa-tional experiences. Children's age and socioeconomic status (SES) were associated with this differentiation. Younger and high-SES children were more likely to view the outcome of procedural jus-tice (i.e., drawing a stick) for allocating an educational experience (i.e., summer camp) as fair when the result favored the resource -rich candidate. Overall, findings revealed that children do not use a unitary form of fairness in the procedural justice context. The shift from strict equality to welfare concerns continues to develop over middle childhood. (c) 2023 Elsevier Inc. All rights reserved.

    Understanding Covid-19 Mobility Through Human Capital: a Unified Causal Framework
    (Springer, 2023-02-21) Bilgel, Fırat; Karahasan, Burhan Can
    This paper seeks to identify the causal impact of educational human capital on social distancing behavior at workplace in Turkey using district-level data for the period of April 2020 - February 2021. We adopt a unified causal framework, predicated on domain knowledge, theory-justified constraints anda data-driven causal structure discovery using causal graphs. We answer our causal query by employing machine learning prediction algorithms; instrumental variables in the presence of latent confounding and Heckman's model in the presence of selection bias. Results show that educated regions are able to distance-work and educational human capital is a key factor in reducing workplace mobility, possibly through its impact on employment. This pattern leads to higher workplace mobility for less educated regions and translates into higher Covid-19 infection rates. The future of the pandemic lies in less educated segments of developing countries and calls for public health action to decrease its unequal and pervasive impact.

    Monitoring of Intracerebral Hemorrhage With a Linear Microwave Imaging Algorithm
    (Springer, 2022-10-29) Dilman, Ismail; Dogu, Semih; Bilgin, Egemen; Akinci, Mehmet Nuri; Cosgun, Sema; Çayören, Mehmet; Akduman, Ibrahim
    Intracerebral hemorrhage is a life-threatening condition where conventional imaging modalities such as CT and MRI are indispensable in diagnosing. Nevertheless, monitoring the evolution of intracerebral hemorrhage still poses a technological challenge. We consider continuous monitoring of intracerebral hemorrhage in this context and present a differential microwave imaging scheme based on a linearized inverse scattering. Our aim is to reconstruct non-anatomical maps that reveal the volumetric evolution of hemorrhage by using the differences between consecutive electric field measurements. This approach can potentially allow the monitoring of intracerebral hemorrhage in a real-time and cost-effective manner. Here, we devise an indicator function, which reveals the position, volumetric growth, and shrinkage of hemorrhage. Later, the method is numerically tested via a 3D anthropomorphic dielectric head model. Through several simulations performed for different locations of intracerebral hemorrhage, the indicator function-based technique is demonstrated to be capable of detecting the changes accurately. Finally, the robustness under noisy conditions is analyzed to assess the feasibility of the method. This analysis suggests that the method can be used to monitor the evolution of intracerebral hemorrhage in real-world scenarios.

    Estimated Probabilities of Positive, Vs. Negative, Events Show Separable Correlations With Covid-19 Preventive Behaviours
    (Elsevier, 2022-06-01) Aksu, Ayça; Booth, Robert W.; Yavuz, Burak Baran; Peker, Müjde
    Research has associated optimism with better health-protective behaviours, but few studies have measured optimism or pessimism directly, by asking participants to estimate probabilities of events. We used these probability estimates to examine how optimism and/or pessimism relate to protecting oneself from COVID-19. When COVID-19 first reached Turkey, we asked a snowball sample of 494 Istanbul adults how much they engaged in various COVID-protective behaviours. They also estimated the probabilities of their catching COVID-19, and of other positive and negative events happening to them. Estimated probability of general positive events (optimism) correlated positively with officially-recommended helpful behaviours (e.g. wearing masks), but not with less-helpful behaviours (e.g. sharing ‘alternative’ COVID-related information online). Estimated probabilities of general negative events (pessimism), or of catching COVID, did not correlate significantly with helpful COVID-related behaviours; but they did correlate with psychopathological symptoms, as did less-helpful COVID-related behaviours. This shows important nuances can be revealed by measuring optimism and pessimism, as separate variables, using probability estimates.

    Adaptive Human Force Scaling Via Admittance Control for Physical Human-Robot Interaction
    (IEEE, 2021-10-01) Başdoğan, Çağatay; Aydın, Yusuf; Hamad, Yahya M.
    The goal of this article is to design an admittance controller for a robot to adaptively change its contribution to a collaborative manipulation task executed with a human partner to improve the task performance. This has been achieved by adaptive scaling of human force based on her/his movement intention while paying attention to the requirements of different task phases. In our approach, movement intentions of human are estimated from measured human force and velocity of manipulated object, and converted to a quantitative value using a fuzzy logic scheme. This value is then utilized as a variable gain in an admittance controller to adaptively adjust the contribution of robot to the task without changing the admittance time constant. We demonstrate the benefits of the proposed approach by a pHRI experiment utilizing Fitts’ reaching movement task. The results of the experiment show that there is a) an optimum admittance time constant maximizing the human force amplification and b) a desirable admittance gain profile which leads to a more effective co-manipulation in terms of overall task performance.

    Culturally Shared and Unique Meanings and Expressions of Maternal Control Across Four Cultures
    (American Psychological Association, 2021-02-01) Selçuk, Bilge; Cheah, Charissa S L; Şen, Hilal H.; Park, Seong-Yeon; Vu, Kathy T T; Cho, Hyun Su; Yavuz, H Melis
    Maternal control is a major dimension of parenting and has different meanings, practices, and potential consequences across cultures. The present study aimed to identify and compare mothers' conceptualizations of parenting control across four cultures to reveal a more nuanced understanding regarding the meaning and practices of control: European American, Chinese immigrant, Korean immigrant, and Turkish. Using a semistructured open-ended interview, 100 European American, 102 U.S. Chinese immigrant, 103 U.S. Korean immigrant, and 109 Turkish mothers of preschool-aged children reported the ratings of importance, specific reasons, and strategies for exerting control over their children in daily life. Results revealed both shared and unique conceptualizations of maternal control across four cultures. Specifically, all mothers reported that it is important to express maternal control over their children in order to set behavioral norms/standards, maintain child safety, support social relations and respect for others, provide guidance, and guide moral development. Moreover, mothers discussed utilizing nonphysical punishment, setting and maintaining rules, reasoning/negotiating, consistency, physical punishment and verbal control, showing parents' serious/stern attitude, correction, and psychological control forms of control. However, the levels at which mothers emphasize the different reasons and strategies varied across cultures, reflecting culturally emphasized values. The findings of the present study further enrich our understanding of the complexities of maternal control across cultures. (PsycInfo Database Record
