Vitamin D deficiency has been associated with schizophrenia and cognitive decline, particularly in executive functions.Objective: To evaluate the relationship between vitamin D levels and performance in executive functions, processing speed, accuracy, and concentration in patients with schizophrenia and other organic mental disorders.Method: Retrospective, cross-sectional study with convenience sampling. The sample consisted of 113 adults (66 with schizophrenia and 47 with other organic mental conditions) admitted to the Institute of Neurosciences of Guayaquil, aged between 22 and 85 years.Results: The findings indicate a significant correlation between vitamin D levels and executive function performance. Higher levels of vitamin D were associated with less decline in executive functions in patients with schizophrenia and organ damage. Processing speed was higher in patients with optimal vitamin D levels compared to those with deficiency. In patients with organ damage, low vitamin D levels were associated with lower accuracy and concentration.Conclusions: This study suggests that adequate vitamin D levels may help preserve executive functions in people with schizophrenia and other organic mental disorders. Vitamin D supplementation is recommended in treatments to improve clinical outcomes and quality of life for these patients. Early detection and intervention are crucial to prevent further cognitive decline.","PeriodicalId":46542,"journal":{"name":"International Journal of Psychological Research","volume":"18 1","pages":"106-114"},"PeriodicalIF":0.8,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12410227/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145151307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Artifact-free EEG epochs were selected for further analysis between conditions. The higher cognitive load affected accuracy, which decreased, while frontal and parietal theta power increased. We also found greater absolute theta power magnitudes for the left-frontocentral locations and a significant interaction between cognitive load and recording site, reflecting the greater increase in left-central parietal locations. Alpha increased in left-frontocentral locations. Although fasting did not consider- ably vary EEG power, there was a relevant fasting-related increase in theta power over frontal areas, probably reflecting transient changes in cognitive control mechanisms.","PeriodicalId":46542,"journal":{"name":"International Journal of Psychological Research","volume":"18 1","pages":"59-68"},"PeriodicalIF":0.8,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12410206/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145151389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The capacity to love involves the ability to engage in, invest in, and sustain a committed romantic relationship, arising from complex developmental processes beginning in childhood and evolving throughout life. Although it may appear as a dispositional attribute, limited evidence exists regarding its association with personality traits.Method: A total of 839 participants aged 18 to 74 were included. Data were gathered using a Sociodemographic Questionnaire, the Big Five Inventory (BFI), and the Capacity to Love Inventory (CTL-I). These instruments were adapted for digital formats and disseminated online.Results: A positive association was found between the personality traits and the CTL dimensions. Four traits -agreeableness, openness to experience, extraversion, and emotional stability- showed a modest contribution to predicting the CTL, with agreeableness emerging as the strongest predictor and most correlated trait. Statistically significant differences also appeared in all the sociodemographic variables examined.Conclusions: These findings indicate a relationship between personality and the capacity to love, thereby enhancing our understanding of personal functioning systems and certain individual difficulties. The results underscore practical implications for tailoring personalized interventions in relationship counseling, emotional regulation, and the development of social skills and empathy, ultimately promoting individual mental health and healthier relationships.","PeriodicalId":46542,"journal":{"name":"International Journal of Psychological Research","volume":"18 1","pages":"69-81"},"PeriodicalIF":0.8,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12410218/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145151369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, it was found that only withdrawal (β = -.49), active coping (β = -.21), and ignoring the problem (β = .24) are statistically significant predictors of depression.

Similarly, 81.7% of Norwegians in the age group 16 to 79 have drunk alcohol in 2021 (Bye, 2018). Driving after the consumption of alcohol is a worldwide problem, causing a large number of deaths and injuries a year. This work proposes the first steps towards developing an electroencephalography (EEG)-based alcohol detector conceived with the idea to prevent people from driving under the influence of alcohol. This includes the design of an experimental protocol for EEG data collection, during which participants performed the Flanker task, and their blood alcohol concentration (BAC) was measured. The resulting data set consists of two sessions per participant, both while they are affected and not-affected by alcohol. Statistical analysis of the Flanker task indicated that participants were affected by alcohol and, therefore, their EEG signals were expected to be affected as well. The collected EEG signals were used as input for intra-subject and inter-subject models, both based on the EEGNet architecture. The intra-subject model obtained a mean classification accuracy of 90.7% and the inter-subject model a mean classification accuracy of 62.9%. The result suggest that alcohol can be detected with high accuracy when developing individual models and above the change accuracy when using a general model. Therefore, the work presented here could be used as the first steps towards the development of an EEG-based alcohol detector for drivers.","PeriodicalId":46542,"journal":{"name":"International Journal of Psychological Research","volume":"17 2","pages":"91-99"},"PeriodicalIF":1.2,"publicationDate":"2024-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11804120/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143383722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
