Executive function (EF) is an umbrella term of cognitive processes (working memory, inhibition, mental set shifting), which are important for achieving goal-directed behaviors. Several contextual and child factors influence EF development. Poverty is a risk factor for EF skills; however, the effects of urban and rural poverty might be different. The current study examined the differences in urban and rural poverty in terms of living conditions and parenting, EF differences in urban and rural poverty, and predictors of EF. The participants were 241 children and their mothers living in poverty. Children’s EF was assessed via Corsi block tapping (visuospatial WM), forward and backward digit span (verbal WM), day-and-night (inhibition), and dimensional change card sort (mental set-shifting) tasks. The results indicated that urban and rural poverty differed in terms of the poverty level (i.e., income, education), home stimulation, neighborhood quality, and mothers’ expectations about children’s educational attainment, whereas they were similar in terms of parenting, conversations with children and mothers’ beliefs about child development. The comparison of urban- rural poverty in terms of EF showed that children living in urban and rural poverty were not significantly different in their EF skills. Moreover, children’s age, duration of attending kindergarten, receptive vocabulary, and children’s perceptual sensitivity were associated with children’s EF; and urban-rural poverty interacted with mothers’ positive parenting predicting children’s verbal WM and mental set-shifting. The findings of the study are important for describing urban-rural poverty differences in Turkey, and the findings have implications for future studies.

Syntactic Recursion Facilitates and Working Memory Predicts Recursive Theory of Mind
Arslan, Burcu; Verbrugge, Rineke (2017-01-10)
In this study, we focus on the possible roles of second-order syntactic recursion and working memory in terms of simple and complex span tasks in the development of second-order false belief reasoning. We tested 89 Turkish children in two age groups, one younger (4;6-6;5 years) and one older (6;7-8;10 years). Although second-order syntactic recursion is significantly correlated with the second-order false belief task, results of ordinal logistic regressions revealed that the main predictor of second-order f...
Patterns of Depression in Medical Patients and Their Relationship with Causal Attrihutions for Illness
Karanci, Nuray A. (S. Karger AG, 1988)
he present study investigated the factor structure of the Beck Depression Inventory (BDI), and causal attributions for the development of illness in a sample of 102 inpatients of a thoracic surgery department, with the main objective of examining the power of causal attributions and functional support in predicting different factors derived from the BDI. The results revealed that the BDI clusters into affective/motivational, somatic/vegetative, self-blame and self-punitiveness dimensions. Causal attribution...
Statistical Approaches for the Analysis of Dependency Among Neurons Under Noise
Gençağa, Deniz; Ayan, Sevgi Şengül; Farnoudkia, Hajar; Okuyucu, Serdar (MDPI AG, 2020-3-28)
Neuronal noise is a major factor affecting the communication between coupled neurons. In this work, we propose a statistical toolset to infer the coupling between two neurons under noise. We estimate these statistical dependencies from data which are generated by a coupled Hodgkin–Huxley (HH) model with additive noise. To infer the coupling using observation data, we employ copulas and information-theoretic quantities, such as the mutual information (MI) and the transfer entropy (TE). Copulas and MI between...
Neuroprotective Efficacy of the Peroxisome Proliferator-Activated Receptor-gamma Ligand in Chronic Cerebral Hypoperfusion
SAYAN ÖZAÇMAK, HALE; SAYAN, Hale; BARUT, FİGEN; Jakubowska-Dogru, Ewa (Bentham Science Publishers Ltd., 2011-08-01)
Chronic cerebral hypoperfusion can cause learning and memory impairment and neuronal damage resembling the effects observed in vascular dementia. PPAR-gamma agonists were shown to modulate inflammatory response and neuronal death following cerebral ischemia. The present study was designed to evaluate possible neuroprotective effects of rosiglitazone, a PPAR-gamma agonist, in rat model of chronic cerebral hypoperfusion. Cerebral hypoperfusion was induced by permanent bilateral occlusion of the common carotid...
Differential modulation of STN-cortical and cortico-muscular coherence by movement and levodopa in Parkinson's disease
Hirschmann, J.; Özkurt, Tolga Esat; Butz, M.; Homburger, M.; Elben, S.; Hartmann, C. J.; Vesper, J.; Wojtecki, L.; Schnitzler, A. (2013-03-01)
Previous research suggests that oscillatory coupling between cortex, basal ganglia and muscles plays an important role in motor behavior. Furthermore, there is evidence that oscillatory coupling is altered in patients with movement disorders such as Parkinson's disease (PD).
