Investigates the effect of instruction to improve the reasoning skills of undergraduates majoring in education. Results indicate the lack of proficiency in formal reasoning by undergraduate education majors in the areas of proportional, probabilistic, and correlational reasoning. Also indicates that deficiencies in reasoning ability in these areas can be successfully addressed. (Contains 30 references.) (Author/YDS)

Introduction: Psychiatric care faces a significant challenge in the regular monitoring of patient states, predicting relapses, and ensuring treatment adherence. To address this, we aim to develop a mobile application tailored to individual patient needs. This application will revolutionize mental health care by offering real-time monitoring, education, evidence-based interventions, and enhanced communication between patients and clinicians. Objectives: This ongoing study seeks to develop and evaluate a mobile application for individuals with schizophrenia spectrum disorders, aiming to transform personalized mental health care by addressing critical challenges in psychiatric care. Methods: The study follows a multi-phase approach, incorporating prototype development, a proof-of-concept trial, and a Randomized Controlled Efficacy Study (RCT). Each phase is informed by iterative stakeholder feedback, ensuring responsiveness to real-world needs and experiences. The research was approved by the Semmelweis University Regional and Institutional Committee of Science and Research Ethics (SE RKEB: 85/2023). Results: In the pilot phase, we have effectively tracked the daily well-being of participating patients through interactive activities and structured questionnaires. Our experiences in this phase promise to offer valuable insights for the psychiatric community, shedding light on the potential of personalized mental health care interventions. Conclusions: This ongoing study represents a pivotal step towards redefining interventions for individuals with schizophrenia spectrum disorders. Early results signal a transformative potential in enhancing symptom management. As the study advances, deeper insights will emerge, emphasizing the profound impact of leveraging mobile technology in personalized mental health care.

Introduction: First episode psychosis (FEP) is the first manifestation of psychotic disorders lasting at least one week, but not longer than 2 years, causing personal suffering and decreased functional outcome of patients. The early intervention in FEP is crucial. Published results on early intervention programmes indicate that during the first 5-10 years relapse prevention and functional outcomes can be improved and mental health care costs can be reduced, compared to treatment as usual. Objectives: Our objective was to examine FEP patients at the Department of Psychiatry and Psychotherapy. Our aim was to create a homogeneous sample and identify factors that can help in early differential diagnosis and therapy. Our goal was to compare the neuropsychological performance and MRI results of patients and healthy controls. Methods: Male and female inpatients hospitalized at our department due to a first psychotic episode and consenting to participate were included, since 2019 October. Cases with drug induced psychosis and organic background in the etiology of the psychotic episode were excluded. Male and female healthy controls were matched by age and education. Including healthy controls is still in progress. The duration of the project is 36 months, 24 months for recruiting patients and healthy controls, 12 month for analyzing data. The investigation includes detailed clinical, neuropsychological examination (baseline, 6th, 12th, 18th, 24th month) and MRI (baseline and in the 24th month). Results: Forty patients and sixteen healthy controls were included. 60% of the patients were rehospitalized due to relapses. Neuropsychological tests (RBANS, faux pas, Baron-Cohen eyes test) indicate cognitive dysfunction compared to healthy subjects. Using resting state fMRI second level analysis we found alterations in thalamo-cortical connectivity. We found significant differences in the connectivity of the thalamus and frontal lobe, postcentral gyrus, insula and cerebellum. Conclusions: Our FEP research, although limited by the COVID-19 pandemic, shows promising results that can help in better understanding of the underlying factors of psychotic disorders.

The exchange bias field dependence on the Mn-oxide and its microstructure in NiFe/Mn-oxide bilayers was investigated. Transmission electron microscopy results have shown that the bilayer bottom consisted of either α-Mn, rocksalt MnO, or a composite of tetragonal Mn3O4+MnO, depending on the ratio of O2/Ar used during dual ion-beam deposition. Magnetometry results at 5 K indicate that the exchange bias field (Hex∼-300 Oe) is largest in a NiFe/Mn (0%O2/Ar) bilayer. The MnO formation by in situ Mn oxidation results in a decrease in Hex in a NiFe/Mn-oxide (21%O2/Ar) bilayer. In contrast, a further increase in the O2/Ar ratio during deposition results in larger Hex and Hc. This is attributed to the oxidation of MnO into a harder ferrimagnet, Mn3O4. Our results indicate that the antiferromagnetic Mn enabled stronger coupling with NiFe than MnO. In addition, we find that the MnO–Mn3O4 coupling dominates the exchange bias effects at high oxygen concentrations. [ABSTRACT FROM AUTHOR]
