Apego ansioso y evitativo de los padres como predictor de ansiedad y eficacia académica de los hijos en la niñez media

Previous work has documented that attachment security is systematically linked with child adjustment and academic competence. This study aims to examine the associations between parents\u27 own report of anxious and avoidant attachment and their children\u27s report of trait anxiety and academic self-efficacy in math and Turkish literature courses. Mothers (N=1539) and fathers (N=1436) from four cities in Turkey, separately completed the measures of attachment orientations, and their children (N=1877), attending 4th and 5th grades, completed the measures of trait anxiety and academic self-concept on math and literature courses in their school. Regression analyses showed that whereas mother attachment anxiety predicted boys\u27 trait anxiety, father attachment avoidance predicted girls\u27 anxiety. In predicting academic self-efficacy, mother attachment avoidance predicted their son\u27s and father attachment anxiety predicted their daughter\u27s academic self-efficacy in both math and literature courses. Our results confirmed the importance of having a warm and secure romantic attachment between spouses in marriage, not only for their relationship satisfaction and happiness, but also for their children\u27s emotional adjustment and academic competence.El trabajo anterior documentó que el apego seguro está sistemáticamente relacionado con la adaptación y las competencias académicas de los hijos. Este estudio pretende investigar la relación entre el informe de los padres sobre el apego ansioso y evitativo y el informe de sus hijos sobre la ansiedad rasgo y la autoeficacia académica en matemáticas y literatura turca. Madres (N=1539) y padres (N=1436) de cuatro ciudades en Turquía completaron por separado medidas de orientaciones de apego y sus hijos (N=1877) que frecuentan la 4ª y la 5ª clase completaron medidas de ansiedad rasgo y autoconcepto académico en matemáticas y literatura turca en su escuela. El análisis regresivo ha mostrado que el apego ansioso de las madres predecía la ansiedad rasgo de los niños, y el apego evitativo predecía la ansiedad de las niñas. Cuando se trata de la autoeficacia académica, el apego evitativo de las madres predecía la autoeficacia académica de sus hijos, y el apego ansioso de los padres predecía la autoeficacia de sus hijas, tanto en matemáticas como en la literatura turca. Nuestros resultados confirman la importancia que tiene una relación romántica segura entre los cónyuges, no sólo para la satisfacción y felicidad en su relación, sino también para la adaptación emocional y la competencia académica de sus hijos

Interaction between varying social ties on health : Perceived partner responsiveness and institutional trust

Publisher Copyright: © 2023 The Authors. International Journal of Psychology published by John Wiley & Sons Ltd on behalf of International Union of Psychological Science.The interplay between different forms of social relationships, that is, perceived partner responsiveness and institutional trust, on subjective health evaluations was examined for the first time. There were 1241 respondents who had a romantic relationship. After adjusting for the covariates, findings suggested that greater perceived partner responsiveness and institutional trust led respondents to report better subjective health. The positive link between perceived partner responsiveness and subjective health was more pronounced among the respondents reporting a lower level of institutional trust. Such an interaction could be an indicator pointing out the compensatory role of close relationship dynamics. Given that finding, public health authorities and practitioners could be encouraged to be aware of the adaptive function of social ties on health and focus on maintaining the strength of intimate social ties and building trust between authority gradients. This suggestion could especially be adaptive not only during “normal” times but also during post-disaster circumstances (e.g., COVID-19).Peer reviewe

Is negativity bias intuitive for liberals and conservatives?

Previous research suggests that conservatives (right-wingers) tend to show more negativity bias than liberals (left-wingers) in several tasks. However, the majority of these studies are based on correlational findings and do not provide information on the cognitive underpinnings of this tendency. The current research investigated whether intuition promotes negativity bias and mitigates the ideological asymmetry in this domain in three underrepresented, non-western samples (Turkey). In line with the previous literature, we defined negativity bias as the tendency to interpret ambiguous faces as threatening. The results of the lab experiment revealed that negativity bias increases under high-cognitive load overall. In addition, this effect was moderated by the participants’ political orientation (Experiment 1). In other words, when their cognitive resources were depleted, liberals became more like conservatives in terms of negativity bias. However, we failed to conceptually replicate this effect using time-limit manipulations in two online preregistered experiments during the COVID-19 pandemic, where the baseline negativity bias is thought to be already at peak. Thus, the findings provide no strong evidence for the idea that intuition promotes negativity bias and that liberals use cognitive effort to avoid this perceptual bias

Increased oxidative stress associated with the severity of the liver disease in various forms of hepatitis B virus infection

BACKGROUND: Oxidative stress can be defined as an increase in oxidants and/or a decrease in antioxidant capacity. There is limited information about the oxidative status in subjects with hepatitis B virus infection. We aimed to evaluate the oxidative status in patients with various clinical forms of chronic hepatitis B infection. METHODS: Seventy-six patients with hepatitis B virus infection, in whom 33 with chronic hepatitis, 31 inactive carriers and 12 with cirrhosis, and 16 healthy subjects were enrolled. Total antioxidant response and total peroxide level measurement, and calculation of oxidative stress index were performed in all participants. RESULTS: Total antioxidant response was significantly lower in cirrhotics than inactive HbsAg carriers and controls (p = 0.008 and p = 0.008, respectively). Total peroxide level and oxidative stress index was significantly higher in cirrhotic (p < 0.001, both) and chronic hepatitis B subjects (p < 0.001, both) than inactive HbsAg carriers and controls. Total antioxidant response was comparable in chronic hepatitis B subjects, inactive HbsAg carriers and controls (both, p > 0.05/6). Total peroxide level and oxidative stress index were also comparable in inactive HBsAg carriers and controls (both, p > 0.05/6). Serum alanine amino transferase level was positively correlated with total peroxide level and oxidative stress index only in chronic hepatitis B subjects (p = 0.002, r = 0.519 and p = 0.008, r = 0.453, respectively). CONCLUSION: Oxidative stress occurs secondarily to increased total lipid peroxidation and inadequate total antioxidant response and is related to severity of the disease and replication status of virus in hepatitis B infection

Effects of Preoperative Anxiety and General Anesthetic Administration on Intraoperative Awareness in Patients Undergoing Cesarean Section

Aim:The aim was to investigate the effects of preoperative anxiety and general anesthetic administrations on intraoperative awareness among patients undergoing cesarean section.Methods:This prospective randomized study included 90 pregnant subjects. Preoperative anxiety was assessed using the Beck Anxiety Inventory. The patients were divided into three groups: group P received propofol 2.5 mg/kg, group T thiopental 5 mg/kg and group K received ketamine 1 mg/kg. Data on intraoperative hemodynamics, isolated forearm (IFA) responses and time to first pain and to first analgesic requirement evaluated using postoperative numerical rating scale were recorded. The Modified Brice Scale (MBS) was used to assess awareness.Results:The preoperative anxiety levels in the groups were low and demographic data were similar (p>0.05). There was no statistically significant difference in IFA response between the groups (p>0.05). Group T had higher MAP at all times and NRS values at hour 0 compared to the other groups (p<0.05), and had shorter time to first analgesic requirement (p<0.05). MBS responses were evaluated as recall in 12 cases in group K, four in group P and three in group T.Conclusion:As the anxiety levels in pregnants were low, the superiority of agents used in induction over each other regarding awareness could not be shown

Intrauterine growth restriction and placental angiogenesis

Background: Vascular endothelial growth factor (VEGF), basic-fibroblast growth factor (b-FGF), and endothelial nitric oxide synthase (eNOS) are factors that take part in placental angiogenesis. They are highly expressed during embryonic and fetal development, especially in the first trimester. In this study, we aimed to investigate the role of placental angiogenesis in the development of intrauterine growth restriction (IUGR) by comparing the levels of expression of VEGF-A, b-FGF, and eNOS in normal-term pregnancy and IUGR placentas.Methods: The expression of VEGF-A, b-FGF, and eNOS was studied using the avidin-biotin-peroxidase method in placental tissues diagnosed as normal (n = 55) and IUGR (n = 55). Results were evaluated in a semi-quantitative manner.Results: The expression of all the markers was significantly higher (p < 0.001) in cytotrophoblasts, syncytiotrophoblasts, extravillous trophoblasts, vascular smooth muscle cells, chorionic villous stromal cells, and villous vascular endothelial cells of the IUGR placentas when compared with those collected from normal-term pregnancies.Conclusion: Increased expression of VEGF-A, b-FGF, and eNOS may be the result of inadequate uteroplacental perfusion, supporting the proposal that abnormal angiogenesis plays a role in the pathophysiology of IUGR. © 2010 Barut et al; licensee BioMed Central Ltd

Measurement of the total antioxidant response using a novel automated method in subjects with nonalcoholic steatohepatitis

BACKGROUND: Oxidative stress, an increase in oxidants and/or a decrease in antioxidant capacity, is one of the potential biochemical mechanisms involved in the pathogenesis of nonalcoholic steatohepatitis. We aimed to investigate the total antioxidant response using a novel automated method in nonalcoholic steatohepatitis subjects. As a reciprocal measure, we also aimed to determine total peroxide level in the same plasma samples. METHODS: Twenty-two subjects with biopsy proven nonalcoholic steatohepatitis and 22 healthy controls were enrolled. Total antioxidant response and total peroxide level measurements were done in all participants. The ratio percentage of total peroxide level to total antioxidant response was regarded as oxidative stress index. RESULTS: Total antioxidant response of subjects with nonalcoholic steatohepatitis was significantly lower than controls (p < 0.05), while mean total peroxide level and mean oxidative stress index were higher (all p < 0.05). In subjects with nonalcoholic steatohepatitis, fibrosis score was significantly correlated with total peroxide level, total antioxidant response and oxidative stress index (p < 0.05, r = 0.607; p < 0.05, r = -0.506; p < 0.05, r = 0.728, respectively). However, no correlation was observed between necroimflamatory grade and those oxidative status parameters (all p > 0.05). CONCLUSION: Nonalcoholic steatohepatitis is associated with increased oxidant capacity, especially in the presence of liver fibrosis. The novel automated assay is a reliable and easily applicable method for total plasma antioxidant response measurement in nonalcoholic steatohepatitis

Oxidative stress in hepatitis C infected end-stage renal disease subjects

BACKGROUND: Both uremia and hepatitis C infection is associated with increased oxidative stress. In the present study, we aimed to find out whether hepatitis C infection has any impact on oxidative stress in hemodialysis subjects. METHODS: Sixteen hepatitis C (+) hemodialysis subjects, 24 hepatitis C negative hemodialysis subjects and 24 healthy subjects were included. Total antioxidant capacity, total peroxide level and oxidative stress index were determined in all subjects. RESULTS: Total antioxidant capacity was significantly higher in controls than hemodialysis subjects with or without hepatitis C infection (all p < 0.05/3), while total peroxide level and oxidative stress index were significantly lower (all p < 0.05/3). Hepatitis C (-) hemodialysis subjects had higher total antioxidant capacity compared to hepatitis C (+) hemodialysis subjects (all p < 0.05/3). Total peroxide level and oxidative stress index was comparable between hemodialysis subjects with or without hepatitis C infection (p > 0.05/3). CONCLUSION: Oxidative stress is increased in both hepatitis C (+) and hepatitis C (-) hemodialysis subjects. However, hepatitis C infection seems to not cause any additional increase in oxidative stress in hemodialysis subjects and it may be partly due to protective effect of dialysis treatment on hepatitis C infection

Yetişkinlikte bağlanma: bir eş-düzenleme göstergesi olarak ses uyumu.

This dissertation aims to explore the concept of coregulation in adulthood based on the analyses of vocal cues in conversations. Moderators which potentially affect vocal coordination between romantic partners were also examined. Twenty-four heterosexual dating couples (Mage = 21.25; SD = 1.03) from Cornell University were recruited for the Study-1. Participants communicated with their romantic and stranger partner in a balanced order. Their conversations were recorded and vocal features were extracted. Granger-causality analyses yielded that close partner conversations were bidirectional, signifying that female participants’ previous F0 responses caused male participants’ subsequent F0 responses and vice versa. In the stranger partner conversations, however, only female participants’ previous F0 responses caused male participants’ subsequent F0 responses, implying that there was unidirectional association between stranger partners. Two-level dyadic HLM analysis demonstrated that there was higher level of synchrony in the conversations of close partners than stranger partners. Furthermore, HLM analysis indicated that the observed synchrony was moderated by attachment-related anxiety and relationship satisfaction. Study-2 examined whether or not the affectionate components of conversations with a close partner could be accurately estimated from intonations only. Participants (N = 156, Mage= 34.75yrs, SD=13.06) were asked to guess whether the pairs of speakers were romantic partners or strangers. They rated 1-minute recordings without verbal content after low-pass filtering applied. The analysis using signal detection theory revealed that close partner vocalizations were recognized above the chance. In sum, findings suggest that coregulation process can be observed at the vocal level using synchronous speech pattern and this process is moderated by attachment anxiety and relationship satisfaction. Implications for attachment-in-the-making between romantic partners and the literature on behavioral mimicry were discussed.Ph.D. - Doctoral Progra
