Neuropsychological analysis in a case of Global Aphasia [Análisis neuropsicológico en un caso de Afasia Global]

2023 , Ramos Galarza, Carlos , Gaibor-Estévez J.

Acquired brain damage generates a series of neuropsychological alterations, among which we can highlight aphasia. This syndrome is characterized by language impairment, with its main features being deficits in fluency, comprehension, repetition, naming, reading, writing and calculation. In this article we present the case of a patient suffering from global aphasia, who presents severe linguistic alterations. The state of the disease and its neuropsychological condition are analyzed. Finally, we close this analysis, highlighting the need for a correct neuropsychological approach at the level of diagnosis and rehabilitation which can help the patient. © 2023 Fundacion para la difusion neurologica en Ecuador - FUNDINE.

Neuropsychological evaluation of inhibitory control and interference control: Validation of experimental tasks in the ecuadorian context

2017 , Ramos Galarza, Carlos , Jadán Guerrero, Janio , Ramos D. , Bolaños M. , Ramos V. , Fiallo-Karolys M.X.

This article reports a study in which three experimental tasks (SIMON, Go / No-Go and Stroop Victoria) were adapted and validated to evaluate the inhibitory control and interference control in a sample of Ecuadorian students. The sample consisted of 100 students between 6 and 15 years old (M = 10.13 years, SD = 2.48) belonging to the public education system of Ecuador. The process followed in the adaptation and validation was through the linguistic translation of the experiments, followed by an expert judgment and a pilot study. In the results it was found that there are no statistically significant differences in the measures that assess the inhibitory control and the interference considering the sociodemographic variables of the participants as comparison factors. In the correlation analysis we found a statistically significant association between the measurements of the experiments. We conclude by analyzing the associations found and underlining the need to continue providing evidence in the research line of adaptation and validation of test for using in neuropsychological evaluation.

Scale of clinical observation to valuate the third functional unit of the Luria theory: EOCL-1. [Escala de Observación Clínica Para Valorar la Tercera Unidad Funcional de la Teoría de Luria: EOCL-1.]

2019 , Ramos Galarza, Carlos , Benavides-Endara P. , Bolaños-Pasquel M. , Fonseca-Bautista S. , Ramos D.

Luria's brain organization model proposes the interaction of three functional units to understand the work performed by the human brain. The first of them is responsible for the regulation of tone and wakefulness. The second one to receive, process and store the information. The third, and of central interest of the investigation, is responsible for programming, executing and verifying mental activity. To evaluate this theory, a series of experimental neuropsychological tests have been developed, however, a scale has not been proposed that, based on the theoretical precepts on the third functional unit, allows to assess it based on the behaviors of the daily life of the human being. This research proposes a scale that will allow the clinician to assess the mental abilities associated with the ability to program, execute and verify the most complex form of mental activity; integrated in the third functional unit of Luria. The proposal is discussed, based on the benefit that is generated by having a scale that will allow to assess this theory, in the different environments where the individual develops through the action of the cerebral abilities of the third functional unit. © 2019 Fundacion para la difusion neurologica en Ecuador - FUNDINE.

Virtual Tours of Museums to Promote Tourism

2024 , Cóndor-Herrera, Omar , Ramos Galarza, Carlos , Bolaños-Pasquel, Mónica

Museums represent a collection of ancient and modern knowledge which must be protected, disseminated, and transmitted in the best viable way. Digital development and technology in recent years have made it possible to transform the way of interacting with museums through virtual tours (Palmieri et al in Springer Series in Design and Innovation, pp 71–82, 2023 [1]), which gained strength in times of pandemic, the products generated for virtual tours range from physical reproductions/faithful virtual images of historical artifacts to digital libraries that can be used by experts and others, in addition to 360º technology which allows a 360° viewing angle to be covered in two axes. That is, we can see everything around the point where it was made the photo or video. In this article, the virtual tours offered by some museums are analyzed, as well as the use of these tours as a tourism marketing strategy, giving the user the opportunity to interact with the place they plan to visit in a new way (Cóndor-Herrera and Ramos-Galarza in Marketing and smart technologies.

Factorial structure of the sense of coherence and its relation with attachment [Estructura factorial del sentido de coherencia y su relación de apego]

2020 , Ortiz-Granja D. , Jayo-Suquillo L. , Ramos Galarza, Carlos

The Sense of Coherence is formed by three factors: comprehensibility, manageability and meaningfulness. In this study, its factorial structure was analyzed through assessment with the SOC-29 scale and its relationship with attachment. Three hypotheses were proposed to assess the reliability, convergent validity and factorial structure, using a sample of 445 participants. Statistical analysis was based on descriptive techniques, Cronbach's alpha, Pearson's correlation and confirmatory factor analysis. The results obtained provide evidence in favor of the hypotheses, with an internal consistency of α=.82, a significant correlation with attachment r=.27 to. 83 and an acceptable fit of the model χ2=1275.88, CFI=.85, RMSEA=.07 [.06-.07], SRMR=.04. The study highlights the importance of the linguistic changes made to adapt the scale to the Ecuadorian context. Two important limitations are mentioned regarding its application as a self-report and the geographical location, which need to be taken into consideration in subsequent studies. © 2020 Instituto Brasileiro de Avaliacao Psicologica.

Proposal for an evaluation scale of executive functions in university students [Propuesta de una escala de valoración de las funciones ejecutivas en universitarios]

2021 , López-Cárdenas M.J. , Ramos Galarza, Carlos

Introduction. The executive functions constitute a set of cognitive, affective and motivational processes, which allow the conscious control of thought, development of highly complex tasks, that is going to facilitate the adaptation to new situations, it is therefore necessary the contribution of new evaluation methodologies of executive functions centered on the university population, this is going to facilitate the access to check the cognitive processes of the pre-frontal cortex. Objective. Evaluate executive functions in university students between 18 and 25 years of age using a self-report scale. Subjects and method. 752 university students from Quito-Ecuador participated, aged between 18 and 25 years old, of whom 498 (66.2%) were female and 254 (33.8%) were male. As measuring reagent, the scale used to evaluate the executive functions in self-report was proposed in the project: Neuropsychological Systems for Supervision of Cognition and Behavior for the Benefit of Managing the Learning of Higher Education Students. Results. Exploratory factor analysis reported an organization of 8 executive functions that explain 57% of the variance of the construct (p = <.001). An adequate level of reliability was obtained between α =.70 and.86, a factor was eliminated since its level of reliability was very low and did not improve under any statistical procedure. The correlation between the proposed factors was adequate at a median magnitude r =.67 and.39. Conclusion. The results show that the proposed scale is based on situations in the student's daily life, this scale design allows identifying both pathological situations and conditions that affect the quality of life and development in the university environment. Furthermore, psychometric indicators provide evidence in favor of their reliable use in the university context. © 2020 Fundacion para la difusion neurologica en Ecuador - FUNDINE.

Scale reduced to value the sense of coherence: SOC 15 [Escala Reducida Para Valorar el Sentido de Coherencia: SOC 15]

2019 , Ortiz-Granja D. , Acosta-Rodas P. , Lepe-Martínez N. , Valle M.D. , Ramos Galarza, Carlos

Introduction: The sense of coherence is a construct of health that allows the individual to face difficult situations of life. It is configured by three factors: meaning, understanding and management. As a method of assessment of this construct, has been proposed the SOC scale with 29 items in its original version. Objective: The objective of this study is to propose a reduced SOC scale. Methods: We worked with a sample of 445 healthy participants from Quito-Ecuador, 145 men (32.5%) and 300 women (67.4%). Results: It was obtained that the reduced scale of 15 items presents an adequate internal consistency in its three factors: understanding α= .74, management α= .82 and meaning α= .82. In the confirmatory factor analysis, an acceptable adjustment of the reduced model was found (SOC-15) x2= 317.90, DF= 87, p= &lt;. 001, CFI= .92, RMSEA= .07 (.06-.08) and SRMR= .04. Conclusions: The data is discussed in relation to the benefits of counting with a reduced scale for its future application in the clinical and health scientific context. © 2019 Fundacion para la difusion neurologica en Ecuador - FUNDINE.

From Face-to-Face Learning to Virtual Learning: Students’ Perspective

2023 , Cóndor-Herrera, Omar , Bolaños-Pasquel, Mónica , Ramos Galarza, Carlos , Cruz Cárdenas, Jorge

This article reports the results found in an investigation which analyzed the perception that students have regarding the virtual learning process developed during the COVID-19 pandemic. The study involved 38 students from a Latin American institution whose age ranged from 13 to 15 years of age, who carried out their academic activities virtually for a school year, once the school period ended, a survey was applied to collect information on the experience in virtual classes, once the results have been analyzed, it is evident that the vast majority of students issued responses in favor of virtual teaching and that virtual classes served to develop their skills in managing technological resources, on the other hand a number of participants They did not indicate the learning experience as positive or negative. This may be related to the fact that a group of participants did not have good quality internet. In the same way, the results reflect that the students consider that not having adequate equipment and good quality internet quality are a limitation in the learning process virtual lift. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Systematic Review of Technological Methods of Evaluation of Executive Functions

2024 , Ramos Galarza, Carlos , García-Cruz P. , Bolaños-Pasquel M.

Executive functions are a set of high-level skills that allow humans to consciously regulate their cognition and behavior. The main executive functions are inhibitory control, planning, working memory, cognitive flexibility, emotional regulation, among others. The use of technological resources is key to evaluate executive functions, since, in today’s society; technological resources are part of the daily life of the human being and must be present in the evaluation processes of these mental abilities. In this context, this article presents a systematic review study that has sought to identify the main technological developments that are used in the evaluation of executive functions. For this study, articles published in the Scopus database were analyzed, finding 350 studies and after the inclusion and exclusion process, we worked with eight studies that developed technological devices to evaluate executive functions. The developed devices have the benefit of assessing executive functions such as inhibition, working memory, decision making, among others. Finally, it is important to mention that technological development in neuropsychological evaluation is still in its beginnings and it is necessary to work on this line of research to have more devices to achieve this goal. © 2024, The Author(s), under exclusive license to Springer Nature Switzerland AG.
